In southeastern regions of the US, herbage systems are primarily based on grazing or hay feeding with low nutritive value warm-season perennial grasses. Nutritious herbage such as annual ryegrass (Lolium multiflorum Lam.) may be more suitable for preserving as baleage for winter feeding even with more intensive production inputs. Emerging in-line wrapped baleage storage systems featuring rapid ...

I. The nutritive value of solubilized wool protein prepared by dissolving finely ground wool in sodium sulphide-sodium sulphite solution followed by precipitation with 40 % acetic acid has been tested by incorporating it into protein-free diets containing the amounts of vitamins and minerals required by weanling rats. 2. At the level of 10 % (w/w) of the diet, solubilized wool protein failed to...

the nutritive value of grass pea (lathyrus sativus l.) hay was evaluated based on its chemical composition, gas production, fractioning of protein in cncps and afrc systems, metabolizable energy (me), rumen degradability through in situ technique and in vitro digestibility through tilley and terry method. the crude protein (cp), neutral detergent fiber (ndf) and acid detergent fiber (adf) value...

Introduction It is only since the beginning of the present century that different proteins have been accredited with different nutritive values. Previously, the proteins in a diet represented purely the necessary nitrogenous fraction, and were ‘proteins’ and nothing more. The conception of differing ‘biological values ’ possessed by different proteins was founded on the experimental work of Max...

The use of high-protein feeds by hvestock feeders to supplement the protein of many common roughages for beef cattle is a general practice based on sound nutrition principles. Protein supplements, as a rule, effect a marked increase in the feed intake of animals on fibrous rations. By providing a better nutrient balance in a ration they increase the efficiency of utilization of the major feed n...

Velvetbean is a relatively cheap source of supplemental protein for ruminants fed low quality forages. However, there is little published information on the maturity stages at which the nutritive value of velvetbean is optimized. This study evaluated the chemical composition, tannin concentration and digestibility of velvetbean harvested at 77, 90, 110, and 123 DAP at the BRU. Dry matter, NDF, ...

This piece of work was directed towards the study of the proximate chemical composition to compare the effect of the different salt concentrations on the nutritive value of fish. In both fresh fish and fassiek (salted fish). Proximate analysis targeted the determination of moisture%, protein%, ash%, fat and pH.

Earlier work showed that the nutritive value of casein was decreased by dry heat and that the addition of lysine restored its nutritive value (1). The lysine was not damaged materially by the heat treatment, since analyses of acid hydrolysates of heated casein with lysine decarboxylase (2) and chemical isolation as the picrate (3) showed no decrease in the lysine content. Eldred and Rodney (2),...

Silage is a common way of storing and feeding forage in the United States. There are 4 phases (aerobic, anaerobic, stable, and feedout) that silage undergoes. The most critical phases to manage to minimize nutritive losses are when the silage is going from an aerobic to an anaerobic environment and at feedout. The first important step in achieving silage of high nutritive value is to harvest at...

Twenty eight lactating buffaloes were used in a completely randomized design with 2×2 factorial arrangement of four experimental diets including low protein–low energy (LP-LE), low protein–high energy (LP-HE), high protein–low energy (HP-LE) and high protein–high energy (HP-HE). Results showed that the HP-HE diet recorded the highest digestibility coefficients of CP, EE, NFE, nutritive values, ...
