Resumo
The objective was to evaluate the use of feeds with different levels of inclusion of water for pigs during the weaning phase. Two experiments were conducted, one of digestibility and other of performance, developed in the Division of Suinoculture of the Department of Animal Production, of the School of Veterinary Medicine of the Federal University of Goiás (DPA / EV / UFG). The treatments in both experiments consisted of physical forms of the experimental feed. The treatment 1 (T1) was a basal dry and mashed feed. Treatment two (T2) and treatment three (T3) consisted of basal feed with the dilution ratio of 1:1 (1 kg of water for 1 kg of ration) and basal feed with the dilution ratio of 2:1 (2 kg water for 1 kg of ration) respectively, mixed and homogenized at the time of suplly and immediately provided to the animals. In the metabolism experiment 12 animals were used, castrated males, with average of 19.09 ± 2.88 kg of live weight. The experimental design suitable for the metabolism testing was the completely randomized, with three treatments and four replication. In the performance test were used 36 crossbred pigs of commercial line, with initial weight of 12.32 ± 1.4 kg, with 18 females and 18 castrated males. It was used the completely randomized design with three treatments and six replication, completing 18 experimental units, where each one was composed by a castrated male and a female. No significant differences were found for the digestibility coefficients of dry matter, crude energy, crude protein, ether extract, the mineral matter in the coefficient of metabolizability of the dry matter and crude energy. However, the rate of metabolism of crude protein was significantly higher for the T2. Diets with different levels of inclusion of water did not affect the animals performance, as well as the initial and final weight, daily and total weight gain, total and daily feed consumption and feed conversion of pigs during the weaning phase
