Nutrient intake and digestibility and milk yield of cows fed with fermented brewer’s grain - DOI: 10.4025/actascianimsci.v32i1.6990
The objective this work was to evaluate the inclusion of 0, 5, 10 and 15% of the fermented brewer’s grain (FBG) in diets of dairy cows on intake and total digestibility coefficient (DC) of nutrients, production and milk quality. Twenty-eight Holstein cows were used, with 100 ± 21 days in milk, and a...

| Sumario: | The objective this work was to evaluate the inclusion of 0, 5, 10 and 15% of the fermented brewer’s grain (FBG) in diets of dairy cows on intake and total digestibility coefficient (DC) of nutrients, production and milk quality. Twenty-eight Holstein cows were used, with 100 ± 21 days in milk, and average body weight (BW) of 612 ± 110 kg, fed with corn silage, ryegrass silage, FBG and concentrate. Intake data and nutrient’s DC, production and milk quality were subjected to regression analysis to 5% of probability. The DM intake of animals was ad libitum. The FBG inclusion levels in diets did not influence (p > 0.05) nutrient intake. The DC of organic matter (OM), total carbohydrates (TCH), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were not influenced by levels of FBG (p > 0.05); however, the DC of DM, crude protein (CP) and ether extract (EE) increased linearly (p < 0.05) with the levels of inclusion in the diets of the RCF. Inclusion of FBG in diets did not influence (p > 0.05) nutrient intake and production and quality of milk. Thus the FBG can be included until 15% in dairy cow diets without changing nutrient intake and production and quality of milk. |
