“…Generally, the superiority in nitrogen retention due to a specific ration is affected by several factors such as possible production of microbial protein synthesis, increasing presence of fermentable energy (Hagemeister et al 1981), differences in availability of fermentable energy (Tagari et al 1976), variability in nitrogen that might escape fermentation from the rumen, an increased utilization of ammonia in the rumen (Holzer et al 1986), and the effect of free fats in protein synthesis (Sutton et al 1983). …”

Twenty-one male growing lambs aged 6 months with an average weight 27.6 +/- 0.24 kg were used to determine the effects of partial replacing yellow corn with potato processing waste (PPW) on performance of Ossimi lambs. Animals divided into three equal groups and assigned for control and two experimental diets containing PPW which was replaced from yellow corn at 0% PPW (R(1)), 25% PPW (R(2)), and 50% PPW (R(3)). The results showed that tested rations were almost isocaloric and isonitrogenous. Dietary treatments had no significant effect on feed intake, while water intake insignificantly decreased. Digestibility coefficients of dry matter, organic matter, and crude protein significantly (P < 0.05) improved. However, dietary treatment had no significant effect on crude fiber and nitrogen-free extract digestibilities. Values of total digestible nutrient and digestible crude protein significantly (P < 0.05) increased. Nitrogen retention was positive for all groups. Dietary treatments had no significant effect on ruminal pH but insignificantly decreased ammonia nitrogen (NH(3)-N) concentrations. However, total volatile fatty acid concentration was increased. Dietary treatments increased molar proportion of volatile fatty acids. Final weight, body weight gain, and average daily gain were significantly (P < 0.05) decreased, while feed conversion ratio insignificantly decreased. Inclusion of PPW decreased total daily feeding costs of experimental rations. PPW could be used as a source of energy in lamb rations instead of corn grain. Also, PPW can be successfully fed to lamb without any adverse effect on their performance, and it can be an economical substitute for grain.

“…Generally, the superiority in N retention in one group than another is affected by several factors. From these, possible production of microbial protein synthesis, increased fermentable energy presence (Hagemeister et al, 1981), differences in availability of fermentable energy (Tagari et al, 1976) availability of N that might escape fermentation from the rumen, an increased utilization of NH 3 in the rumen (Holzer et al, 1986) and the effect of the free fats in protein synthesis (Sutton et al, 1983).…”

he objective of this study was to compare between fresh ryegrass and ryegrass silage in the ability of sheep to consume the material, retained its nitrogen in their body with a special reference of some inorganic elements. A digestibility and nitrogen and minerals balance trials were conducted to compare between fresh ryegrass and ryegrass silage. Twelve mature cross breed rams aged 4 years old and weighted around 42 kg in average were assigned randomly into two experimental groups, 6 animals each and fed the fresh ryegrass (grass group) and its ryegrass silage (silage group) as a sole source of feedstuffs in the rations. Results indicated that dry matter (DM) intake and digestion were reduced by feeding silage (P<0.05), whereas dry matter digestibility in the fresh ryegrass group was equivalent to that in the ryegrass silage (P>0.05). Lead intake and retention was higher in fresh grass group than silage group (P<0.05). Values of nitrogen intake and retention were insignificant (P>0.05) higher in grass group than silage group. There was no significant difference (P>0.05) between grass group and silage group for sodium, magnesium, manganese, iron, cobalt, cupper. Whereas, values of potassium, calcium and zinc (intake and retention) were (P<0.05) higher in grass group than silage group. It could be concluded that fresh ryegrass was the better when compared with ryegrass silage but preserving ryegrass as silage to be used in the rations of ruminant is favorite during fodder scarcity season.
