Six rams with an average body weight of 70. kg and 3 years of age were used and assigned randomly into two similar groups. The supplemented feeding ratio was 50% concentrate feed mixture as main diet for two  experimental ram groups and 50% of treatment rations (berssem hay, potato by-products hay). Berseem hay was supplemented as control group and  second group was nourished offered to potato by-products hay (PB-PH). Nitrogen balance and nutrients digestability were determined for experimental groups and studying sperm characteristics which collected three consecutive ejaculates daily up to fourteen successive days using a warm artificial vagina with estrous ewe for mounting, liquid nitrogen for sperm incubation period through three hours was determined with post thawing spermatozoa. The obtained results indicated that the rams fed the ration contained PB-PH were significantly (P<0.05) lower in experimental testes (nitrogen retention, and thawing sperm characteristics during incubation time at 370C for 3 hours) than rams given BH ration . The overall means of total motile, normal and concentration number sperm / ejaculates x109 were 1.31, 1.47 and 1.75, with PB-PH ration while control group recorded 1.63,1.75 and 1.99,respectively during epididymis depletion. The PB-PH post-thawing sperm motility, live and normal were 43.00%, 40.30% and 44.00%,respectively. time at 370C for 3 hours) than control group. The incubation post-thawing sperm characteristics for deferent experimental rations and incubation time three hours were highly significant (P<0.05). The overall means of PB-PH treatment were 31.25%, 28.72% and 32.52%  while, control were 39.38 , 33.88 and 40.26 for post-thawing motility, live and normal, during incubation respectively. Sperm characteristics decline through the incubation times because of lactic dehydrogenase (LDH), lactic acid and aromatic amino acid oxidase (AAAO) releasing gradually.   }, keywords = {rams,Digestion,nitrogen retention,and incubation times}, url = {https://jappmu.journals.ekb.eg/article_82937.html}, eprint = {https://jappmu.journals.ekb.eg/article_82937_2c2a4b4e41186dd372460b964b7160f0.pdf} } @article { author = {El-Arian, M. and Shalaby, N. and Khattab, A. and Darwish, S. and Abou-Gamous, R.}, title = {PHENOTYPIC AND GENETIC TRENDS FOR SOME MILK YIELD TRAITS OF EGYPTIAN BUFFALOES}, journal = {Journal of Animal and Poultry Production}, volume = {3}, number = {7}, pages = {353-364}, year = {2012}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3642}, eissn = {2090-3723}, doi = {10.21608/jappmu.2012.82938}, abstract = {A total number of 600 female buffaloes, having 3321 lactation records, from first to tenth parity, kept at three experimental farms (Mahalet Mousa, El-Nataf El-Gaded and El-Nataf El-Kadem), belonging to the Animal Production Research Institute, Ministry of Agriculture, Cairo, Egypt, during the period from 2000 to 2007 were used to study genetic and phenotypic progress, achieved by the Mixed Model Equations (MME) for the Best Liner Unbiased Prediction. The number of sires were 66 sires and the average number of daughters per sire were 12.50. Mixed Model Least square analyzed was used to estimate fixed effects of month and year of calving, parity and farm on (total milk yield (TMY), lactation period (LP), fat yield (FY), protein yield (PY), lactose yield (LY) and somatic cell count (SCC).  Data were analyzed using Multi Trait Animal Model to estimate genetic parameters and breeding values. Unadjusted means of TMY, LP, FY, PY, LY and SCC were 2070 kg, 223 d, 164.4 kg, 89.5 kg, 128.2 kg and 204.8 x 10-3 cells/ml, respectively.  Heritability estimates (± SE) of TMY, LP, FY, PY, LY and SCC were 0.41 ± 0.06, 0.31 ± 0.07, 0.20 ± 0.09, 0.19 ± 0.03, 0.22 ± 0.10 and 0.06 ± 0.03, respectively.  Estimates of genetic correlations among milk yield traits were positive and ranged from 0.18 to 0.8, while the genetic correlation between SCC and all milk traits are negative and ranged from -0.18 to -0.66.  Phenotypic correlation among all traits studied were the same direction of genetic correlations. The range of expected sire breeding values (SBV's) for milk traits were 1418 kg, 13.27 d, 178 kg, 91 kg, 139 kg for TMY, LP, FY, PY and LY, respectively. Annual phenotypic change for TMY, LP, FY, PY and LY were positive  and highly significant, being 74.20 kg, 18.84 d, 7.48 kg, 2.89 kg and 2.10 kg, respectively. The corresponding annual genetic change for the same above traits averaged 3.70 kg, 0.55 d, 0.90 kg, 0.60 kg and 0.54 kg, respectively.  Positive genetic and phenotypic trends in the present results indicated that the selection plan of that herds was use the best sires, so that in the next generation will excepect genetic improvement for traits under investigation except the SCC of lactating Egyptian buffaloes at these herds. }, keywords = {}, url = {https://jappmu.journals.ekb.eg/article_82938.html}, eprint = {https://jappmu.journals.ekb.eg/article_82938_0ad2aa1c48bc40ba2118cd698b8d88d0.pdf} } @article { author = {Dorra, Tork and Ibrahim, Samya and Zayed, Sh.}, title = {EFFECT OF DIETARY BETAINE SUPPLEMENTATION ON GROWTH PERFORMANCE AND CARCASS TRAITS OF GROWING TURKEY}, journal = {Journal of Animal and Poultry Production}, volume = {3}, number = {7}, pages = {365-377}, year = {2012}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3642}, eissn = {2090-3723}, doi = {10.21608/jappmu.2012.82940}, abstract = {The responses of growing turkey to different dietary levels of betaine were investigated during the period from 12 to 20 weeks of age. Therefore, a basal diet was formulated to contain 21.37% CP and 3057 Kcal ME/kg. This diet was supplemented with betaine at levels of 0, 75, 150 and 225 g/100 kg diet. Thus, there were four treatment groups; each was fed to 50 birds (males and females) divided equally into two sub-groups of 25 males and 25 females in each. Results revealed that birds in T3 (150 g betaine/100 kg diet) showed the highest (P≤0.05) final LBW and total weight gain (TWG) as compared to control birds or those in other treatment groups. The superiority in final LBW of birds in T3 was associated with improvement (P≤0.05) in growth measurements including breast width and length of keel, back, shank, tibia and thigh as compared to other groups. Birds in other treatment groups (T2 and T4) did not differ significantly in growth performance parameters from that of the control birds. Males showed better (P≤0.05) growth performance parameters than females. The interaction effect between treatment x sex on all growth performance was not significant. Concentration of total proteins (TP) and albumin (AL) in blood plasma of T3 and T4 groups increased (P≤0.05) as compared to the control ones. Males showed higher (P≤0.05) concentrations of TP, AL and AL: GL ratio than females. Birds in T3 showed the highest (P≤0.05) weights of carcass, giblets, gizzard, liver and heart as well as the highest percentage of giblets. Carcass and gizzard and dressing percentages were not affected by dietary betaine treatments. Males showed higher (P≤0.05) weights of carcass, giblets, gizzard, liver and heart. Females showed the highest (P≤0.05) giblets, gizzard and liver percentages. The interaction effect between treatment x sex on all carcass traits was not significant. Birds in T3 showed the highest economic feed efficiency (EFE %) as compared to other treatment groups. Males showed higher EFE than females. In conclusion, growth performance, blood parameters including protein metabolism, carcass traits and economic efficiency were improved by supplementing diet of grower turkey with 150 g betaine /100 kg diet.   }, keywords = {turkey,Betaine,Growth performance,carcass quality}, url = {https://jappmu.journals.ekb.eg/article_82940.html}, eprint = {https://jappmu.journals.ekb.eg/article_82940_c09a95b1c3cd3c6986d49f216f2f099b.pdf} }
