Productive performance of goat kids fed of crude glycerin/Desempenho produtivo de cabritos alimentados com glicerina bruta

This study was conducted to evaluate the productive performance of crossbred goats finished in feedlots fed diets containing increasing levels of crude glycerin (0, 4, 8 and 12%, DM basis). Twenty crossbred goat kids were used in a randomized complete block design with 4 treatments and 5 replications to determine average daily gain (ADG), dry matter intake (DMI) and nutrients (CP, NDF, EE) and ingestive behavior. For digestibility trial, four castrated male goats were used in a Latin Square Design to determine the DM and nutrients digestibility. Crude glycerin did not affect (P>0.05) the ADG, DMI and nutrients intake. Eating time increased linearly (P0,05) dos tratamentos sobre o tempo gasto na ruminacao e digestibilidade da MS, PB e FDN, contudo, houve efeito quadratico para a digestibilidade do EE. Recomendase a inclusao em ate 12% de glicerina bruta para cabritos em terminacao, em situacoes de oscilacao do preco do milho, sem alteracao nos parametros produtivos avaliados. Palavras-chave: confinamento, consumo, desempenho, glicerol.
