Resumo
The objective of the present study was to evaluate the performance, carcass
characteristics and digestibility of diets with low or no bulk food inclusion in Dorper
X Santa Ines lambs finished in a feedlot. The treatments consisted of five
complete diets: Commercial Feed Corte Confina® (CCONF), commercial
Concentrate Corte 20® plus Bagasse (CB), commercial Concentrate plus Corn
and Bagasse (CMB), commercial Concentrate plus Corn, Soybean hulls and
Bagasse (CMCSB) and commercial Concentrate plus Soybean hulls and Bagasse
(CCSB). The performance study was carried out in the Goat and Sheep Sector at
the Federal Institute Goiano - Campus Rio Verde – Goiás - Brazil. Twenty intact
F1 Dorper x Santa Ines lambs were used, average age 60 days and average
weight 20.34±39 kg at the start of the experiment. A complete randomized design
was used. The experiment lasted 85 days and the animals were weighed every 21
days. The digestibility experiment was carried out in the experimental installations
at the Food Analysis Laboratory of the Animal Production Department at the
Veterinary and Animal Science College of the UNIVERSIDADE FEDERAL DE
GOIÁS Goiânia – Brazil. A 5 x 5 Latin square was used to evaluate the apparent
digestibility and intake performance. Samples of the diets used in the performance
experiment were incubated to evaluate the in vitro dry matter degradability. The
means were compared by the Fisher DMS test (α = 0.05). The diet did not affect
(P>0.05) either performance, where the mean general weight gain was 232.4
g/day for 4.78 food conversion, or the carcass characteristics. The fatty acid profile
of the carcass was altered. The intake performance was not affected and the food
conversion was not altered.
