Twenty four weaned of Farafra male lambs 5 months age and weighed in average 16.69 ± 2.65 kg, were used in a feeding trial for 120 days in a complete block design. Animals were divided according to their live body weight into three experimental groups (8 lambs each), Ration 1 (R1) consists of 60% CFM + 40 % rice straw (control), R2: (40% CFM + 40% GGF + 20 % rice straw and R3: (40% CFM + 40% GFS + 20% rice straw). GGF and GFS were used to cover a partial of protein from CFM. The experimental rations fed according to NRC (1985). Results indicate that the apparent digestibility coefficients of all nutrients and feeding value of rations containing (GG) or (GFS) were better (P<0.05) compared to the control ration. Percentage of apparent N-utilization was currently higher (P<0.05) for the guar green forage and guar forage silage (R2 and R3) rations than the control ration (R1). Significant increased (P<0.05) were reported on total feed intakes, total weight gains, average daily gains (ADG) and better feed conversion ratios (FCR) and economic efficiencies for groups R2 and R3 compared with control group. The realized ADG were 198.08 and 185.83 g/day for R2 and R3, respectively, while lambs of the control recorded 177.11 g/day. No significant differences among experimental diets in serum total protein, albumin, globulin, trans-aminase enzymes (AST and ALT), cholesterol, triiodothyronine (T3) and Thyroxin (T4) hormones. It could be concluded that, feeding guar green forage or guar forage silage up to 40% as partial replacement of concentrate feed mixture for Farafra growing lambs rations were recommended. Such rations resulted in superior nutrition, better daily gain, feed conversion and economic efficiency.}, keywords = {performance,digestibility coefficients,nitrogen balance,guar green forage,Guar green forage silage,Farafra male sheep}, url = {https://jappmu.journals.ekb.eg/article_45763.html}, eprint = {https://jappmu.journals.ekb.eg/article_45763_ad0f82a0898922cbf55493a55945fb2e.pdf} } @article { author = {Maged, G. and El-Kholany, M. and El-Emam, G. and Elsayed, F. and El-Sawah, T. and Aboul-Omran, Aboul-Omran and Al-Mowafy, A.}, title = {Response of Milk Production of Dairy Zaraibi Goats to Feeding Rations Containing Different Levels of Sesame Seeds Unsuitable for Manufacturing as an Inexpensive and Untraditional Source of Protein.}, journal = {Journal of Animal and Poultry Production}, volume = {8}, number = {3}, pages = {49-54}, year = {2017}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3642}, eissn = {2090-3723}, doi = {10.21608/jappmu.2017.45769}, abstract = {The effect of using sesame seeds (SS) at differentilevels in rationsiof lactatingigoats on theiriperformance forimilk production andifeed conversion efficiencyiwas studied.

Animals divided according to their body weight, parity and milk production in previous season. Control does (CON) received a diet without supplementation, whereas in treated group a solid feed supplement rich in glucogenic substances, colloidal silica and organic cobalt was used namely glucogenic mixture (GM) supplementation. The GM contained mainly of three major glucogenic additives (glycerin, propylene glycol and calcium propionate). The GM was incorporated daily as a rate of 50 g/head/d. The trial period lasted for 6 weeks, (2 weeks pre-parturition and 4 weeks post-parturition). Blood samples were collected week before parturition and week post-parturition for hematological and biochemical estimations. Milk yield was measured biweekly for each doe and milk samples were taken. Results revealed that the feed intake in terms of total DM was not clearly affected as compared between GM supplementation and control groups. With supplementing does the blood triglyceride, AST, ALT, β-hydroxybutyrate and cholesterol concentrations were significantly decreased. Higher significant concentrations of glucose, insulin and thyroid hormones were detected in supplemented group. Moreover, supplementing the does with GM improved most of tested blood hematological parameters during the transition period. Additionally, heavier weights of kids at birth, at 15 and 30 d of age were obtained, as well as no kids' mortality cases were recorded by supplementing does with GM. The GM supplementation resulted in about 15.89 and 16.43 % increases in daily milk yield at 15 and 30 days of does' lactation, respectively. At 30 days of lactation, supplemented group showed significantly higher milk fat, protein, ash and total solids percentages. Furthermore, as a result of GM supplementation the economic efficiency value was noticeably higher. The results demonstrated thatglucogenic mixture supplementation not only supply sufficient energy, but also improve the general health status and milk yield of dairy Zaraibi does as well as modify the composition of their milk.}, keywords = {glucogenic supplementation,glycerin,propylene glycol,calcium propionate,colloidal silica,transition Zaraibi does}, url = {https://jappmu.journals.ekb.eg/article_45776.html}, eprint = {https://jappmu.journals.ekb.eg/article_45776_db8c1017585de84977f6d088f7179db8.pdf} } @article { author = {Nagy, W. and Abo-Farw, M. and El-Ratel, I. and Abdel-Khalek, A.}, title = {Buffalo Oocytes Maturation In Vitro as Affected by Vitrification of Whole Ovaries or Oocytes}, journal = {Journal of Animal and Poultry Production}, volume = {8}, number = {3}, pages = {63-67}, year = {2017}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3642}, eissn = {2090-3723}, doi = {10.21608/jappmu.2017.45777}, abstract = {Aim of this paper is to find the possibility of in vitro maturation of buffalo oocytes recovered from vitrified whole ovaries. Ovaries from slaughtered buffaloes (n=400) were collected; out of these ovaries, 150 were fresh and 250 buffalo ovaries were vitrified and thawed. Number of all visible follicles was recorded on fresh ovaries and on each ovarian surface pre- and post vitrification, then oocytes recovery rate was calculated in fresh or vitrified ovaries. Oocytes were recovered by aspiration. From the recovered oocytes from fresh ovaries, COCs were vitrified by straw cryodevice. Post-thawing, morphologically normal oocytes from vitrified or fresh ovaries were vitrified. Results showed that numbers of total and normal follicles, and total and normal oocytes per ovary were significantly higher in fresh than in vitrified ovaries. Total number of abnormal follicles showed significantly (P<0.01) an opposite trend, while, the difference in number of abnormal oocytes/ovary was not significant. Oocytes recovered from fresh ovaries showed significantly higher recovery and normality rates than those recovered from vitrified ovaries. Percentage of compact and expanded oocytes was significantly higher, while percentage of denuded and partial denuded oocytes was significantly lower when oocytes were recovered from fresh than from vitrified ovaries. Maturation rate (MII-oocytes percent) was higher (P<0.05) when oocytes were recovered from fresh than from vitrified ovaries and those vitrified after recovery (62.50% vs. 35.90 and 27.50%, respectively). In conclusion, vitrification of the whole buffalo ovaries is a positive tool for genetic sources cryopreservation in term of beneficial effects on in vitro maturation of oocytes when compare with those directly vitrified after recovery from fresh ovaries.}, keywords = {Buffalo,Vitrification,whole ovary,oocyte,in vitro maturation}, url = {https://jappmu.journals.ekb.eg/article_45777.html}, eprint = {https://jappmu.journals.ekb.eg/article_45777_4f48aab9aa2c57827148db1d1c2e4f27.pdf} }
