Crude glycerin in meat goat diets: intake, performance and carcass traits
ABSTRACT: This experiment aimed to evaluate the effect of including glycerin in kid goats diet on intake, performance and carcass traits. Twenty intact male kid goats Boer crossbred were used, with body weight of 25.06±4.15kg and 8.00±0.66 months old, allocated in block design, with four treatments and five replicates. The treatments consisted on including dry matter basis (DM) of the diet of four levels of glycerin: zero, five, 10 and 15%, in replacing corn. It was not reported influence (P>0.05) of level of glycerin on intake of forage and feed conversion of animals. The concentrate and total DM intake were affected (P<0.05) for the level of glycerin in DM, with reduction in the animals that received the highest level. It was not reported influence (P>0.05) of level of glycerin on weight gain, carcass yield and percentage of cooling losses. However, the hot and cold carcass weight was lower (P<0.05) to the animals feed with 15% of glycerin. The inclusion up to 15% of glycerin in the diet of kid goats Boer crossbred, although did not affect feed conversion and performance, compromised the intake and carcass weight.
