Effects of adding different proportions of brewer's grains on growth per-formance,serum biochemical indices,slaughter performance and meat quality of fattening goats
The aim of this study was to investigate the effects of different proportions of brewer's grains on growth per-formance,serum biochemical indices,slaughter performance and meat quality of fattening goats.Twenty-four 3-month-old Jianzhou Da'er goats with good body condition and similar body weight were divided into four groups and fed with diets supple-mented with 0,42.90%,48.00%and 53.00%brewer's grains,respectively.The experiment lasted for 70 days,with a pre-feed-ing period of 14 days and a formal period of 56 days.The results showed that compared with the control,the average economic profit per goat was significantly increased by adding48.00%brewer's grains to the diet.This treatment had no adverse effects on serum biochemical indices,slaughter performance,and visceral indices,and improved the meat quality of goats to a certain ex-tent.In conclusion,under the conditions of this study,the optimum proportion of brewer's grains added to the feed of Jianzhou Da'er goat was 48.00%.
