The objective of this study was to evaluate the influence of sources of nitrogen on the intake and digestibility of nutrients and production and chemical composition of goat milk. Soybean meal (SBM), soybean meal + urea (SBM+U), cottonseed meal + urea (CM+U), cottonseed cake + urea (CC+U) and whole cottonseed + urea (WC+U) were used, representing the different sources of nitrogen in the diet. Ten crossbred goats were used (Alpine + Saanen), weighing on average 47.90±1.94 kg of body weight […]
Keywords: cottonseed meal; milk constituents; NDFi; nitrogen balance; ttonseed cake; whole cottonseed

Six Nellore bulls, with initial body weight of 420 kg, were used to evaluate cromium oxide determined by X-ray fluorescence as an external markers of digestibility. Cromium oxide was compared to internal indicators: indigestible NDF (NDFi) incubated in vitro for 144 hours and acid detergent lignin and total feces collection. Digestibility coefficients of DM, OM, NDF, ADF, CP and EE were estimated. Experimental diets were: 1) soybean meal, in a RDP deficient diet; 2) urea; 3) starea (non protein nitrogen […]
