摘要

Foram avaliadas 120 matrizes de coelhas durante dois ciclos reprodutivos. Os animais foram distribu赤dos em um delineamento experimental inteiramente casualizado, com 4 tratamentos (ra o sem 車leo e ra o com 3% de 車leo de canola, de 車leo de milho ou de 車leo de soja) e 30 repeti es. Foram coletados os dados de peso vivo das coelhas em cada cobri o, no parto, aos 21 e aos 35 dias de lacta o e de consumo durante a gesta o, os primeiros 21 dias de lacta o e durante o per赤odo total de lacta o (35 dias). Tamb谷m foram obtidos os dados referentes ao peso vivo e ao n迆mero de l芍paros ao nascimento, aos 21 e aos 35 dias. N o foram observadas diferen as (P%26gt;0,05) entre os tratamentos quanto aos parametros de desempenho das coelhas no primeiro ciclo reprodutivo. No entanto os dados referentes ao segundo ciclo demonstraram maior peso vivo (P0,05) pela utiliza o das ra es. One hundred and twenty rabbit does, were evaluated during two productive cycles. The animals were distributed in a completely randomized experimental design, with four treatments (oil-free rations and 3% canola oil, corn oil or soybean oil rations) and 30 replications. While data of live weight of rabbit does were collected in each breeding, on birth, on the 21st and the 35th days of lactation, those on feed intake were recorded during gestation, onthe first 21 days of lactation and during the total period of lactation (35 days). Data on the litters live weight and number on birth, on the 21st and the 35th days, were also obtained. There were no differences (p%26gt;0.05) among treatments with regard to performance parameters of rabbit does on the first reproductive cycle. However, data concerning the second cycle demonstrated a better live weight (p0.05) by rations containing different sources of vegetable oil fed during the two reproductive cycles.
