“…These results were in agreement with those found by El-Badawi et al (2003) and Mousa (2011). 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), 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).…”

n order to study the effect of chitosan, pectin and vitamin C tools for removing heavy metals (HM's) from diets and as antioxidant and its effect on goats performance, experimental diets consisted of concentrate feed mixture (CFM) plus acacia forage irrigated with wastewater, were served as control (D1); D1 plus 5 gm /head/d chitosan (D2); D1 plus 20 gm/ head /d purified pectin (D3) and D1 plus 500 mg/head/d vitamin C (D4). Twenty lactating Zaraibi does in the 2 nd and 3 rd season of lactation with 34.5 kg in average body weights were used for feeding trial. They were randomly divided into four equal groups (5 does each). While twelve Zaraibi bucks 50.2 kg weight were used in four digestion trials. For rumen fermentation trials, three does fitted with permanent rumen fistula were used. Goats were offered acacia forage ad libitum twice a day at 8.00 and 16.00 plus restricted amount of CFM to cover 50% of protein requirements according to NRC (2007). Results showed that: 1-Acacia plant had lower pH than that of wastewater or soil; while all HM's in acacia were higher than that in wastewater or soil; 2-Digestibility coefficients, nutritive values and nitrogen utilization of goats fed diet supplemented with pectin or vitamin C had significantly highest (P<0.01) values, followed by diet supplemented with chitosan, while control diet was recorded the lowest values. 3-Ammonia-N concentration was decreased (P< 0.01) with chitosan, pectin or vitamin C supplementation; while VFA's concentration was increased; 4-Molar proportion of VFA's in rumen of goats showed that acetic acid concentration was higher in D3 and D4 than other diets, while propionic acid had the highest (P< 0.05) value with group supplemented with chitosan, and no significant difference among treatments was found respecting butyric acid concentration; 5-Pectin or vitamin C addition lead to an increase in ruminal bacteria numbers and their activities, not only that, but they had higher (P< 0.01) for microbial protein (MP) syntheses as well; 6-Milk production was significant increased with all supplemented groups and in the meantime does showed significantly better feed conversion compared with control one; 7-Serum glucose, cholesterol, urea, AST and ALT in blood were significantly (P<0.01) decreased by the supplementation of chitosan, pectin or vitamin C compared with control diet. While, serum total protein, albumin and globulin were significantly (P<0.05) increased; and 8-Heavy metals residues in the feces of chitosan, pectin or vitamin C groups was showed high values compared with the control group. But their residues in the blood serum and milk were fewer values compared with the control group. It could be concluded from this study that supplementation with chitosan, pectin or vitamin C could improve goats' performance and remove of HM's from blood and milk . However, the use of pectin or vitamin C could come in the first priority versus chitosan that come in the least priority.

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.

“…One probable explanation for the increase in the nitrogen balance could be related to the improvement in the production of microbes and, as a result, increased production of microbial protein. In addition, the improvement in nitrogen balance could be related to the increase in the utilization of ammonia [ 31 ] and/or due to the availability of fermentable carbohydrates in the rumen.…”

Aim:The aim of this study was to evaluate the effect of feeding low (LO)- or high (HI)-fiber diets supplemented with Saccharomyces cerevisiae (SC) on nutrient intake, digestibility, nitrogen balance, rumen fluid pH, and serum concentrations of glucose and urea nitrogen in Awassi female lambs in a 2×2 factorial arrangement of treatments.Materials and Methods:Experimental diets were as follows: (1) LO-fiber diet with no SC supplementation (−LO), (2) LO-fiber diet supplemented with SC (+LO), (3) HI-fiber diet with no SC supplementation (−HI), or (4) HI-fiber diet supplemented with SC (+HI). Eight female lambs were used in a replicated 4×4 Latin square design with 15-day experimental periods (10-day adaptation period and 5-day collection period).Results:A fiber×SC interaction (p≤0.05) was detected for dry matter (DM) and crude protein (CP) intake among diets showing greater DM and CP intake for +LO diet compared to +HI group supplemented with SC, whereas −LO and −HI were intermediate. A fiber×SC interaction (p=0.05) was also detected for the neutral detergent fiber (NDF) intake among diets. Intake of NDF was greater for the –HI diet compared with +LO and –LO diets. Similarly, NDF intake was greater for +HI diet than –LO diet. A tendency (p=0.07) for a fiber×SC interaction was detected for acid detergent fiber (ADF) intake among diets as well. ADF intake tended to be greater for HI-fiber diets. No difference was observed in the rumen fluid pH for lambs fed with the different diets. No fiber×SC interactions were detected for the digestibility of DM, CP, NDF, and ADF among dietary treatments. Digestibility of DM was greater (72.9 g/100 g vs. 67.1 g/100 g; p=0.0002) for LO versus HI fiber. However, NDF and ADF digestibilities were greater (60.8 and 61.9 g/100 g vs. 55.8 and 52.7 g/100 g for NDF and ADF digestibility, respectively; p≤0.01) for the HI-fiber than the LO-fiber diets.Conclusion:Results obtained in the current study indicate that SC supplementation has a minimal effect on the performance of Awassi female lambs fed with varying fiber levels.
