(Universidade Federal de Goiás, 2019-09-09) Abreu, Morgana Pontes; Santos, Marcos Veiga; http://lattes.cnpq.br/8345833429933187; Cordeiro, Clarice Gebara Muraro Serrate; http://lattes.cnpq.br/5073363015303780; Zacaroni, Ozana de Fátima; http://lattes.cnpq.br/4582215859105753; Zacaroni, Ozana de Fátima; Cunha, Paulo Henrique Jorge da; Carmo, Adriana Santana do
Mastitis is the most prevalent disease in dairy cattle, leading to substantial production losses and having a multifactorial etiology. Its occurrence in herds is associated with the health of the animal, environment, and management practices. Numerous risk factors have been described for the disease, one of which is hyperkeratosis. This condition is characterized by the accumulation of large amounts of keratin and the proliferation of corneal tissue, primarily due to mechanical forces exerted by milking equipment. Thus, the objective of this study was to evaluate teat morphometry, the occurrence of hyperkeratosis, somatic cell counts, and the correlation of these parameters with zootechnical data in 269 dairy cows (47 Gir and 222 1/2 Girolando) from the same farm. Following approval by the Animal Use Ethics Committee (CEUA) under protocol number 054/18, data were compiled on breed, number of lactations, days post-partum, peak milk production in the current lactation, somatic cell count, teat length, width, and hyperkeratosis. Hyperkeratosis was classified in scores, with scores one and two considered mild, and three and four severe. One anterior and one posterior teat of each cow, always contralateral, were evaluated. The data were tabulated in Excel 2010® and analyzed in R® using Analysis of Variance, Binary Logistic Regression, and odds ratio tests, with a significance level of 5%. No difference was found in teat length between Gir and Girolando cows; however, Gir cows had wider teats than Girolando cows. Girolando teats and cows showed a higher likelihood of developing severe hyperkeratosis compared to Gir cows. Anterior teats had a 68% higher chance of developing severe hyperkeratosis. Regarding length, the longer the teat, the greater the chance of severe hyperkeratosis, regardless of breed. Zootechnical data showed differences only for lactation period and number of lactations. Cows with two or more lactations were more likely to develop severe hyperkeratosis than primiparous cows, and the longer the postpartum period, the greater the occurrence of severe hyperkeratosis. In conclusion, on the same farm, 1/2 Girolando cows are more susceptible to severe hyperkeratosis than Gir cows.

The Brazilian Mangalarga Marchador breed stands out on the national scene for being the largest in number of specimens, approximately 747 thousand horses. These horses are registered by the Mangalarga Marchador Horse Breeders Association, considering zootechnical controls, mainly of morphometric measurements. Traditional methods for performing morphometric measurements, such as the use of a hippometer, can be used for this control, but their use can lead to measurement errors due to the movement of the animal, and risk to the professional and the animal due to contact during the measurement. Therefore, the investigation of other measurement methodologies is essential, such as the use of mathematical models that predict morphometric segments, using images taken by smartphone. The objective of this study was to use two-dimensional images to predict morphometric measurements and to evaluate the automation of the prediction of morphometric measurements through convolutional neural networks (CNN). For the first stage, the models were developed using multiple linear regression (MLR), Support vector regression (SVR), and random forest (RF) methodologies. The factors sex, weight, stud farm, and segment of interest were considered for the development of the models. As a result, only sex did not obtain a positive result regarding the influence on the results, since there was not an insufficient number of animals to conclude the influence, despite the literature suggesting that it is an important factor. The methodologies addressed had good results regarding weight prediction, with similar results among the three, thus the most indicated is the MLR due to its simplicity. The second stage consisted of analyzing the images through CNN, an automatic evaluation methodology. CNN obtained good results, reaching a MAPE value of less than 10%. Thus, it can be stated that both manual and automatic prediction are capable of reliably predicting equine morphometric measurements.

Entomopathogenic fungi and nematodes are biocontrol agents widely investigated for the biological control of several pests, including ticks. This study aimed to determine the efficacy of fungi and nematodes, combined or not combined, against Rhipicephalus microplus engorged females under laboratory and field conditions. Bioassays under controlled conditions were conducted to evaluate the pathogenicity of the nematode Heterorhabditis bacteriophora HP88 against R. microplus females with different weights (150, 200, 250, 300, and 350 mg), and against females from eight different populations. In addition, a study under field conditions were conducted to evaluate the efficacy of H. bacteriophora HP88 formulated on Tenebrio molitor cadavers for controlling non-parasitic R. microplus on infested pastures. Likewise, a study was sought to determine, under controlled conditions, the synergistic combination between Metarhizium spp. and H. bacteriophora HP88 against R. microplus engorged females, as well as to determine a granular formulation containing M. robertsii IP 146 microsclerotia with potential to produce conidia when incubated onto different substrates. Lastly, a study was conducted to determine, under field conditions, the efficacy of combined granular formulation and H. bacteriophora HP88 infective juveniles (third stage) for controlling non-parasitic R. microplus population on infested pastures during different seasons of the year (wet or dry). Nematode pathogenicity to R. microplus females did not show variation of the percent control (98.4% to 97.5%) on the groups with different weights. There were also no differences on susceptibility of females from different populations (percent control between 89% and 99%) to HP88. In the field test, non-parasitic R. microplus population was reduced by 73.1% in the plots treated with H. bacteriophora HP88. Combined treatments with Metarhizium spp. and H. bacteriophora HP88 reduced biological parameters of engorged females, with additive effect detected. However, treatmented with M. robertsii IP 146 combined with H. bacteriophora HP88 sub-doses demonstrated synergism. The field test conducted in the wet season reduced the non-parasitic R. microplus population on infested pastures, with efficacy of 54.09% (fungus only), 38.11% (nematode only), and 46.72% (fungi and nematodes combined). In the dry period, only the fungal treatment reduced R. microplus population, with efficacy of 26.27%. We concluded that M. robertsii IP 146 and H. bacteriophora HP88 are promising agents for biological control of the non-parasitic phase of R. microplus, although the treatment efficacy had varied according to the wet or dry seasons.

Agricultural Defense is responsible for ensuring the origin, conformity and safety of products of animal origin intended for human consumption. Food safety depends on compliance with ood manufacturing practices, inspection and correct application of technical norms and standards established in the country. Official laboratory analysis constitutes a relevant regulatory instrument, supporting inspection actions through product monitoring. The lack of management in testing laboratories generates uncertainty regarding the carrying out of activities and results in results with a lower degree of reliability and lack of traceability. To this end, its implementation transforms the analytical rite, assessing innovative management and internationalization of the laboratory ecosystem. In this sense, the objective of this study was to describe the process of implementing a Quality Management System in an official state laboratory for analyzing foods of animal origin, in accordance with the International Organization for Standardization (ISO) 17.025-2017. Initially, a situational diagnosis was carried out in the laboratory intended for this purpose, linked to the government of the state of Goiás named the Food Quality Control Laboratory (LABQUALI); In a second stage, the viability of the laboratory management system (QMS) in the current laboratory structure and the public administration's adherence to execution and restructuring were assessed. The third stage involved the implementation of the QMS and the fourth stage, the critical analysis of the consistency of previous actions for the effectiveness of the new laboratory management. All instruments for enabling the ISO 17.025-2017 standard were declared as necessary requirements and awareness was raised by the state Agricultural Defense Agency of Goias (AGRODEFESA) for the implementation and implementation of the standard. Documents, records were created and prepared, internal documents were issued. There was a broad flow of external documents, creation of manuals, writing of administrative, managerial and technical reports. For physical and financial execution, a schedule for acquisitions, human resources training, internal and external audits, proficiency tests, statistical process control and adaptation of all physical infrastructure and administrative, technical and scientific structure were prepared in relation to the requirements of the General Coordination of Accreditation (CGCRE) from the National Institute of Metrology, Quality and Technology (INMETRO). The results obtained attested that the QMS proposed to LABQUALI met the requirements determined by the reference standard and was in line with what was recommended regarding the precepts and intentions for governance of the state of Goiás. In addition to laboratory quality management, it was verified that the communication with the state structure through the insertion of computerization of the laboratory system into the agency's digital platform and innovative action, compared to the other states of the federation and the Federal District. Another important result refers to LABQUALI's adherence to the Goiás Public Compliance Program. It was concluded that the creation of a laboratory management system generated numerous benefits for AGRODEFESA and the state. The existence of responsibility, reliability and traceability actions for the accuracy of results in food analysis, contributing to the growth and qualification of the official inspection service in the state of Goiás, also corroborates risk monitoring. The QMS implementation model for LABQUALI could support other official laboratories seeking qualifications to master laboratory management for regional and national development
Óleos essenciais para controle de carrapatos: revisão das pesquisas com testes em condição de campo e avaliação de eficácia de combinações de carrapaticidas com (E)-cinamaldeído para controle de Rhipicephalus microplus

The Rhipicephalus microplus tick was originally found infesting ruminants in South Asia and transported on zebu cattle to other locations in the world. This arthropod causes direct damage to the hosts, being the biggest cause of economic losses in livestock worldwide. In Brazil, with 224.6 million cattle, estimates point to losses of more than 3 billion dollars annually. The control of this parasite is carried out almost exclusively with synthetic acaricides. However, the constant and sometimes incorrect and indiscriminate use of these products can accelerate the selection of resistant ticks. Research to develop technologies to control ticks has been carried out, such as the use of vaccines, biological control agents and essential oils (EOs). Cinnamon (Cinnamomum zeylanicum) EO and its derivative (E)-cinnamaldehyde have acaricides activities. Some EOs and compounds present in EOs (CEOs) showed good acaricide results, including the association between them and synthetic products in vitro and in vivo studies, but these studies are scarce. The present study reviewed the literature with EOs and CEOs for field and semi-field tick control between the years 1991 and 2021 and investigated the effect of the combination of (E)- cinnamaldehyde and amitraz in the laboratory and in the field to control R .microplus. Twentyeight studies were selected in the review, of which 53.6% were carried out in Brazil, 71% with the application of EOs and CEOs in animals and 29% in the environment. In these studies, the spray application method was the most used (75%). The bovine species was the most studied (70%) and the tick R. microplus the most researched (46.4%). From this field and semi-field review, we realized the still limited number of articles evaluating the use of EOs and CEOs, and further studies under these conditions are needed to assess the real potential of these substances for tick control. In this sense, some aspects need to be prioritized: the characterization of the EOs, the standardization of the methodologies used in the efficacy evaluation tests, the use of EOs and COEs combined with synthetic acaricides (looking for synergistic interactions), the development of formulations and the evaluation of the application safety for animals, humans and environment. In vitro tests were carried out with 116 populations of ticks from all regions of Brazil, with 14 synthetic products, and those with 50-80% efficacy was chosen, having only one active ingredient. Subsequently, the products based on amitraz and chlorfenvinphos were tested in binary combinations with (E)-cinnamaldehyde in a tick strain, called CM strain, which showed better results for amitraz. The best association of (E)-cinnamaldehyde and amitraz was used in pharmacotechnical studies for the development and characterization of formulations, evaluating the in vitro and in vivo efficacy to control R. microplus infestations and clinical safety for cattle. The approach of combining this CEO and the synthetic product improved the effectiveness of the latter (reaching 86%) in engorged females (in vitro), but in the field study with application on animals, (E)-cinnamaldehyde caused intoxication in cattle. Future research, seeking to reduce the toxicity of formulations with (E)-cinnamaldehyde, deserves to be investigated.
Aspectos anatômicos dos músculos caudais e mediais da coxa do quati (Nasua nasua, Linnaeus, 1766)

South american carnivores, members of the Procyonidae family, the coatis (Nasua Nasua) are generalist omnivores that found on fruits the important component for their diet. Thereby, they forage not only on the ground but also in the trees, showing themselves to be skilled climbers. This skill requires more strength and mobility of their hindlimbs when compared to those of their closest relatives, the dogs, with whom they share the same Suborder Caniformia. Thus, it was examined the anatomical aspects of the muscles that integrate the caudal and medial muscular groups of the thigh of coatis, which had its general aspects, location, shape, origin, insertion, syntopy and basic actions evaluated. Both hindlimbs of five adult animals (two females and three males) donated by IBAMA GO (License: 98/2011) were used in this study, which has its protocol approved by the CEUA-UFG (protocol 235/2011). Of these, three animals were euthanized (SISBIO/ ICMBio license: 26278-3). They were fixed with 10% formaldehyde solution and stored in tanks within the same solution, in which they remained for at least 72 hours before the beginning of dissection procedures. Subsequently, they were kept in tanks with ethylic alcohol at 92.8º GL. This doctorate thesis generated two scientific articles. In the first one titled ANATOMICAL ASPECTS OF THE CAUDAL THIGH MUSCLES OF COATI (Nasua nasua, LINNAEUS 1766), it was verified that muscles which comprise the caudal muscular group of the thigh of coatis are the m. semitendinosus, m. semimembranosus, m. biceps femoris and the m. abductor cruris caudalis. The m. semitendinosus has two heads, long and short, besides an intersection tendon. It does not contribute to the formation of the common calcaneal tendon. The m. semimembranosus is incompletely divided into cranial and caudal parts. The m. biceps femoris has only one head and also does not contribute to the formation of the common calcaneal tendon. The ligamentum sacrotuberale is absent and the m. abductor cruris caudalis originates from the deep surface of the m. gluteofemoralis and adjacent part of the m. gluteus superficialis. The second article titled ANATOMICAL ASPECTS OF THE MEDIAL THIGH MUSCLES OF COATI (Nasua nasua, LINNAEUS 1766), it was verified that muscles which comprise the medial muscular group of the thigh of coatis are the m. gracilis, m. pectineus, magnus, brevis and longus adductors muscles and the m. external obturator. All these muscles show particularities regarding to its origin and/or insertion. The m. gracilis is very broad and does not contribute to the formation of the common calcaneal tendon. The m. pectineus extends up to the half of the caudal surface of the femur. The three individual adductors are arranged like three layers that increase craniocaudally, being the adductor brevis positioned between the longus cranially and the magnus caudally. Several anatomical changes were observed in the caudal and medial thigh muscles of coatis in relation to domestic dogs muscles, with some of these, however, resembling more the anatomic patterns of felids. Probably these changes are related to the climbing skills acquired by the coatis during their evolutionary process.

Extreme Learning Machines, Extreme Machine Learning (EML/IGASE), unlike other Artificial Neural Network (ANN) training algorithms that adjust network parameters through the iterative presentation of training patterns, include intermediate neuron numbers and perform projection random in the hidden layer, in general of high dimensionality in the complex connections with the other variables of direct inputs, the weights are selected in a random way injected and bijected in the complex composite functions, without need of training. The over- sizing of the EML/IGASE becomes necessary for the smoothing of the response, guarantees the capacity of generalization and transfers of complex functions in the temporal series of phenotypic expressions of the animals. The objective of this work is to predict the average weight gain at weaning (GMPD) phenotype as a function of direct variables measured in animals within and between seasons (SF) and farms (FAZ), using EML/IGASE. 8,812 progeny records were used for 11 harvests, descendants of 272 bulls, from 09 farms located in different states of the federation, Mato Grosso (MT), Mato Grosso do Sul (MS), Paraná (PR) and São Paulo (SP). ). The phenotypes studied were weight at weaning (PD), average weight gain at weaning (GMPD), conformation at weaning (CPD), musc ulature at weaning (MPD) and early weaning (PPD). Extreme Machine Learning (EML/IGASE) was able to predict the mean weight gain at weaning (GMPD) phenotype, based on the other variables measured in the animals within and between seasons and farms studied, with low Mean Squared Error (MSE) in the robust interactions and transfers of complex functions from multi-input neural architectures and different levels of environmental attributables to the expressed phenotypes. In the univariate analyzes with the input variable weights at weaning (PD) transferring to the average weight gain at weaning (GMPD) the EML/IGASE performed complex numeric al predictions in 08 productive harvests of the 09 farms, where the Mean Squared Errors (EQM) between predicted and actual variables of GMPD ranged from 0.09 to 13.96%. For the multivariate analyzes with the four input variables weight at weaning (PD), conformation at weaning (CPD), musc ulature at weaning (MPD) and precocity at weaning (PPD) in 09 harvests of the 09 productive farms, the Mean Squared Errors (NDE) between predicted and actual GMPD variables ranged from 0.08 to 26.30%. The complex transfer functions were robust to noise tests up to the second decimal place in the numeric al predictions considered in the study.

This thesis aimed to investigate the use of available P (AP) in diets of teleost fish species, considering its effects on growth, health, bone development and mineralization of skeletal structures. For this purpose, scientific experiments were conducted to determine the quantitative and qualitative implications of the consumption of diets containing levels of adequate dietary correspondence, below and above the specific nutritional requirements of each species. The results of these studies resulted in the elaboration of two scientific articles, whose approaches and main features are described below. The first article aimed to determine the nutritional requirement of AP for tambaquis (Colossoma macropomum) in the final growth phase (± 400 to 1000 g). The results indicated that AP supplementation did not affect the growth of tambaquis fed plant-based diets, and the diets containing 4.1 g/kg of AP. were sufficient to sustain growth in the evaluated phase. However, for adequate mineralization of the whole body and mineralized structures, the level in the diet of tambaquis is 10.3 g/kg AP. The second article investigated the impacts of AP. deficiency and the effect of restoring the mineral in the diet in three species of teleost fish: tilapia (Oreochromis niloticus), pirapitinga (Piaractus brachypomus) and panga (Pangasius pangasius). The results showed that phosphorus deficiency increased body fat deposition, however, restoring the AP supply was not able to completely reverse this adiposity. The dynamics of mineral deposition in mineralized structures was speciesspecific, with the cephalic bones being the main source of mineral mobilization in situations of deficiency. The findings indicate that reestablishing the AP supply after a long period of deficiency is able to restore the physiological well-being of the fish evaluated in this study. The results obtained highlight the importance of assessing the impacts of phosphorus deficiency at different stages of rearing and the use of appropriate parameters to determine the level of AP in the diets of teleost fish. Although bone abnormalities are visible and relevant indicators, they represent only a part of the consequences of phosphorus deficiency, with the metabolic and physiological effects being less apparent. Therefore, a more comprehensive approach focusing on parameters related to the physiological well-being of teleost fish can contribute to more sustainable and environmentally friendly aquaculture
