Influence of Distillers Dried Grain Solubles (DDGS) on Intake, Nutrients Digestibility and Milk Production of Dairy Buffaloes
Journal Title: JOURNAL OF BIOLOGICAL ENGINEERING RESEARCH AND REVIEW - Year 2018, Vol 5, Issue 1
Abstract
The effects of distillers dried grain solubles (DDGS) was assessed on its influence in milk production, milk components, nutrient digestibility and economic viability when fed to dairy buffaloes. Fourteen (14) Brazilian and Bulgarian buffaloes with 624kg average body weight were randomly assigned in three dietary treatments, namely; T1 - roughage + dairy concentrates (RDC, control diet); T2 - R+ 75%DC + 25%DDGS and T3 – R + 50%DC + 50%DDGS. The buffaloes were on their second parity and last month of gestation. The dietary treatments had uneven replications with 5 replicates each for R1 and R2 while the R3 with 4 replicate buffaloes, arranged in a randomized complete block design (RCBD). Results showed numerical increase in milk production and milk composition however, these disclosed no significant differences between treatments. Buffaloes fed diet with 50% DDGS significantly increase the crude protein (CP) intake, while 25% in the diet increased the neutral detergent fiber (NDF) intake. In terms of digestibility, NDF digestibility was shown to be higher in 25% level than in 50% DDGS. The digestion coefficients for CP revealed comparable values in 25% and 50% DDGS in the ration. Incremental sales benefit from the milk of buffaloes fed with 25 and 50% DDGS were significant compared to buffalo cows without DDGS. The highest income over feed cost (IOFC) was observed in buffalo cows fed with 25% DDGS.
