nine multiparous lactating cows averaging 171 days in milk were divided according to days in milk and milk production into three 3×3 latin squares with three 3-week periods to investigate the effect of rumen degradable protein on milk urea nitrogen. diets were formulated to provide 3 concentrations of dietary rumen degradable protein (9.8, 10.8, and 11.8% of dry matter), while rumen undegradabl...

Three cannulated Tswana steers were used to investigate the rumen degradability of mopane worm (Imbrasia belina) by measuring the amount of dry matter (DM) and crude protein (CP) disappearing at incubation periods up to 72 h. The effective degradability (ED) of DM and CP in the rumen was calculated at outflow rates of 0.03 / h (ED0.03) and 0.05 / h(ED0.05). Rumen degradable CP (RDP) was estimat...

A study was undertaken on lucerne (LUC), ryegrass (RG), kikuyu (KIK), soybean meal (SBM), wheat grain (WG) and meat and bone meal (MBM) to determine the effect of animal species (sheep versus cattle) on in sacco degradation of dry matter (DM) and protein. The approach of cubic smoothing splines ®tted as a linear mixed model was used for the analysis of degradability of DM and protein of feeds. ...

Degradable hydrogels to deliver bioactive proteins represent an emerging platform for promoting tissue repair and vascularization in various applications. However, implanting these biomaterials requires invasive surgery, which is associated with complications such as inflammation, scarring, and infection. To address these shortcomings, we applied microfluidics-based polymerization to engineer i...

21 Three levels of metabolizable protein supply (108, 98–95 and 85 g PDIE kg DM) (PDIE: protein digested in the small intestine when rumen-fermentable energy is limiting) in the diet and three levels of difference between rumen-degradable 21 energy and N (PDIE 2 PDIN 5 0, 10 and 20 g kg DM) (PDIN: protein digested in the small intestine when rumenfermentable nitrogen is limiting) were used in t...
