The current study was carried out to evaluate the impact of inbreeding on lamb weight at birth (BW), weaning (W90) and yearling (W360).This study used the pedigree records of 1290 Sohagi lamb progenies of 44 sires and 491 dams reared at experimental farm, Faculty of Agriculture, Sohag University from 2001 to 2021. Non-genetic factors effect on studied traits was investigated. Average of BW, W90 and W360 were 2.98±0.01, 15.05±0.07, and 32.61±0.17 kg, respectively. The results showed that 34.34% of the current dataset were inbred animals. Inbreeding coefficients of inbred animals ranged from 0.02 to 37.5%, averaging 6.57%. Inbreeding regression coefficient on birth year for overall inbreeding coefficient was -0.0003 and that for inbred animals (-0.01) was significantly negative (P<0.01). BW and W90 decreased by 0.004 and 0.002 kg for each 1% increase in the inbreeding coefficient together with an increase of 0.009 kg in W360. The results of rank correlation of Spearman between estimate breeding values (BV's) of animals obtained from adding or not adding inbreeding coefficient of lambs as a covariate term showed no changes of animals ranking. It was concluded that inbreeding showed negligible effect on studied body weight traits. Also, to reduce the level of inbreeding, increasing number and replacement of rams for mating can be a successful strategy.

This study aimed to evaluate 2-months pre- and 3- months' post-partum dietary supplementation of Aspergillus oryzae (AO) extract (Amaferm®) or malate salt (MS) on productive performance of buffalo cows. Multiparous buffalo cows (n=15, 446.92±26.54 kg LBW, and 2-5 parities) at late pregnancy period were divided into three groups., The control group was fed a basal ration, while the 2 nd and 3 rd groups received the basal diet with 15 g/h/d of AO and 10 g/h/d MS, respectively. Results indicated that AO supplementation improved (P<0.05) DM and OM digestibility during post-partum, while CF digestion, feeding values, and ruminal TVFA’s concentration were increased (P<0.05) by MS and AO. Treated groups increased (P<0.05) milk yield and composition, MS group recorded the highest benefits. AO addition improved (P<0.05) milk production persistency during lactation period. Economic efficiency had increased (P<0.05) for AO and MS groups by 4.6 and 13.3% compared with the control, respectively. Dietary AO supplementation (15 g/h/d) 2 months pre- and 3-months post-partum improve nutrient utilization and productive performance of multiparous buffalo cows.

Eleven growing one-humped male camels with an average initial body weight of 251.36±6.97 kg were used. After finishing period of 5-month, camels were approximately 2.5 years of age with an average body weight of 359±1 kg. This study aimed to evaluate association analyses between identified SNPs in myogenic factor 5 (MYF5) and growth hormone (GH) genes and live body measurements, carcass merits and meat quality of one humped camel were performed. One region of MYF5 and two regions of GH (GH3UTR and GH5UTR) genes were tested to identify the SNPs in one humped camel. The results shown that detected SNPs in MYF5 and GH had a significant influence on several body measurements, carcass characteristic, histological traits, and chemical composition. The three regions were found to associate with several meat characteristics, and it is recommended that could be used as a candidate gene to characterize meat of dromedary camels. More researches are required to confirm the influence of MYF5 and GH genes on meat quantity and quality of camels.

The present study aims to investigate the effects of orally quaffed antioxidant (as a source of vitamin E) throughout 7 weeks on growth performance, digestibility coefficient and carcass traits, hematological, and serum biochemical, and economic efficiency parameters of the growing black Balady rabbit males. Eighteen rabbits with an average body weight (436.75 ± 10.87 g) were randomly allotted into two experimental treatments as T 1 and T 2 ( n =9; rabbits/treatment), which were individually subdivided into three replicates ( n =3; rabbits/replicate). All rabbits in T 1 served as a control treatment and fed basal diet plus orally quaffed a dosage of coconut oil as a carrier material of vitamin E up to 2.0 mL / kg live body weight (LBW) / two times weekly. However, T 2 rabbits were fed the same basal diet and orally quaffed a dosage up to 2.0 mL of antioxidant (each mL contain 7 mg of vitamin E) / kg LBW/ two times weekly. The results cleared that, rabbits in T 2 significantly (P<0.05) enhanced all growth performance parameters, digestibility coefficient (%), nutritive values (%), carcass characteristics, and serum biochemical measurements compared to those in T 1 . Oxidative capacity status was significantly improved in T 2 rabbits relative to T 1 rabbits. The economic efficiency and relative economic efficiency parameters were higher in T 2 than T 1 rabbits. Conclusively, orally using vitamin E as an antioxidant agent could be a useful tool for improving the productive performance, and physiological, and oxidative status parameters, besides its economic benefits for rearing native black Balady rabbits.
本试验旨在研究7周内口服抗氧化剂(作为维生素E的来源)对生长中的雄性黑巴拉迪兔生长性能、消化系数、胴体性状、血液学、血清生化和经济效益参数的影响。选取18只平均体重(436.75±10.87 g)的家兔，随机分为t1和t2两组(n =9;兔/处理)，每组再细分为3个重复(n =3;兔子/复制)。试验1组所有家兔作为对照，饲喂基础饲粮，并口服椰子油作为维生素E的载体物质，剂量为2.0 mL / kg活重，每周2次。2只兔饲喂相同的基础饲粮，每周2次，每公斤体重/公斤口服抗氧化剂2.0 mL(每mL含7 mg维生素E)。结果表明，与t1相比，t2显著(P<0.05)提高了兔的所有生长性能参数、消化系数(%)、营养价值(%)、胴体特性和血清生化指标。与t1兔相比，t2兔的氧化能力状态显著改善。t2兔的经济效率和相对经济效率参数均高于t1兔。综上所述，口服维生素E作为抗氧化剂，除了具有一定的经济效益外，还可以提高本地黑巴拉迪兔的生产性能、生理和氧化状态参数。

This research was carred out at Ras-Hederba-Valley area belonging to Desert Research Center. Where aimed to investigate the influence of the production systems (intensive and semi-intensive) on the carcass characteristic, quality, and sensory evaluation of Abo-Deleek meat. Fourteen Abo-Deleek lambs (seven in each group) aged approximately one year were slaughtered after raising for six months in two different production systems in terms of intensive (G1) and semi-intensive (G2) systems. Cold carcass and wholesale cuts were weighted. Meat samples were collected and conducting meat analysis and sensory evaluation. The main results obtained that, there was no significant differences between two groups according to cold carcass weight, all wholesale cuts, best ribs weight, dissection of best ribs (lean, fat and bone) and longissimus dorsi (LD) muscle area. Also, the chemical composition and physical traits of lambs meat were similar in both groups except water binding capacity where recorded a high value in the G2 (54.14 %) compared to G1 (48.01 %). While sensory evaluation traits were high in G2 compared to G1 ( p <0.05). Moreover, there were a correlation between sensory traits and chemical content of meat particularly collagen and minerals ( p <0.05). Therefore, the present study concluded that Abo-Deleek sheep could be reared under semi-intensive system which enhanced the palatability of meat and without any negative effects on wholesale cuts and meat quality.

The study goal was to find out how hens fed Arabic gum (AG) powder affected performance and blood chemistry of breed chicken. The experiment included one hundred and eighty AL-SALAM local chicken breed14 days old. The criteria for response were average weight increase, feed intake, feed conversion ratio, dressing %, non-carcass component (heart, gizzard, and liver), and chemical analysis of blood serum parameters were applied as a standard for responding. Results showed that the group fed 5% (AG) as an addition increased daily gain, live weight (1710 gm), decreased feed intake (3320 gm), feed conversion ratio, carcass traits at the end experimental, those results were increased highly significant (P≤ 0.05) compared to the control group that received a control diet without (AG). There were no notable variations in the blood analysis results (P≤ 0.05) at the conclusion of the trial period, the economic efficiency of each group was determined. Significant Arabic Gum addition to the control diet (P≤ 0.05) improved the general performance of chicks. It could be concluded that the feed supplemented with 5% (AG) lead to lowest value of feed consumption and obtained the highest performance and total profit.

A total of 4889 birth weight (BW) records on calves of 1609 Friesian cows in Sakha experimental farm were collected between 1975 and 2020 year. The analytical model included the fixed effects of the parity, calving year and season, age at first calving, gestation period length and calf sex. Variance components, heritabilities, direct maternal correlations and breeding values (BV) were estimated using VCE6 program . Genetic trends of calves BW were evaluated by regressing BV on years of calving using GLM process of SAS software. Results showed highly (P≤ 0.001) significant effects of all studied fixed effects on BW. Direct (h 2a ), sire (h 2s ), maternal (h 2m ) and total (h 2t ) heritabilities and direct maternal correlations (r am ) estimates were 0.01, 0.10, 0.05, 0.09 and 0.01, respectively. Estimated BVs of calves, sires and dams ranged from -6.71 to 6.84, -6.04 to 4.38 and -7.29 to 8.86 kg, respectively. Range of BVs for dams was higher than for sires and calves, but the accuracy of calves BVs were higher than others. The genetic trend was not different from zero showing no indication of change in the genetic merit of BW in this farm during the period of study.Dam selection proved to be important for inducing high genetic progress in BW during the subsequent generation. Moreover, BV estimates of calves BW achieved higher accuracy ranging from 0.69 – 0.81% comparing to those for sires and dams by indirect selection. However, improvement in calves BW may also be achieved by practicing better management programs in this herd.

Direct (h 2a ), sire (h 2s ), maternal (h 2m ) and total (h 2t ) heritabilities and direct maternal correlations (r am ) estimates were 0.01, 0.10, 0.05, 0.09 and 0.01, respectively. Estimated BVs of calves, sires and dams ranged from -6.71 to 6.84, -6.04 to 4.38 and -7.29 to 8.86 kg, respectively. Range of BVs for dams was higher than for sires and calves, but the accuracy of calves BVs were higher than others. The genetic trend was not different from zero showing no indication of change in the genetic merit of BW in this farm during the period of study.Dam selection proved to be important for inducing high genetic progress in BW during the subsequent generation. Moreover, BV estimates of calves BW achieved higher accuracy ranging from 0.69 – 0.81% comparing to those for sires and dams by indirect selection. However, improvement in calves BW may also be achieved by practicing better management programs in this herd.","PeriodicalId":14889,"journal":{"name":"Journal of Animal and Poultry Production","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78095880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we overviewed the influences of orally provided bee pollen (BPO) and Mannan-oligosaccharides (MOS) suspension on the biochemical, hematological and immunity parameters and antioxidant activity of growing rabbits. Rabbits of 35 days of age weight (751.8±68.8 g) were distributed into four groups (20 rabbits per group); control group; bee pollen (200 mg/kg BW), MOS (35 mg/kg BW) and a combination group (BPO+MOS) for eight weeks. MOS treated group with significantly increased PCV in comparison with BPO and BPO with MOS. Group treated with combination BPO with MOS had the highest WBCs in comparison with the other treatments and control. The treated rabbits with MOS significantly increased glucose levels, while the means of cholesterol significantly decreased less than the control group. BPO and MOS had a significantly higher T3 hormone in comparison to the control group. The treated rabbits with BPO and MOS had significantly decreased liver enzymes and urea less than those of the control group. Furthermore, Rabbits treated with BPO and/or MOS also showed decreased malondialdehyde, but increased total antioxidant capacity and phagocytic activity. Conclusively, adding BPO and MOS to growing rabbits enhances cell-mediated immune response, hematological and biochemical parameters reflecting and raising immunity and antioxidative responses.

This investigation was established to assess the effect of dietary different copper sources and levels supplementation on growth performance, plasma biochemical parameters and antioxidant activities of broiler chickens. Four hundred and twenty-one-day-old chicks (Ross 308) were randomly allocated into 7 experimental treatment (n= 60 birds per each).At the end of the experiment, results obtained revealed that birds fed basal diet with inorganic or organic Cu had significantly (P < 0.05) better live body weight, weight gain and feed conversion ratio, while feed intake was reduced comparison with control group. Chicks supplemented with organic CuNo3 significantly (P < 0.05) improved growth performance s compared with the other groups. Considerable reductions in plasma total cholesterol and triglyceride, high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDL-C) were detected in the group that fed diet with 125 mg / kg diet Cu in comparison with other diets. Plasma glutathione (GPX), superoxide dismutase (SOD) and total antioxidant activity (T-AOC) were significantly enhanced with Cu-supplemented diets, while malondialdehyde (MDA) was significantly declined in the experimental groups compared with the control group. In conclusion, Cu supplemented at level of 125 mg/ kg diet either copper nitrate or copper sulfate improved the productive performance, profile of lipid metabolism and oxidative response enzymes of broiler chickens. Broilers fed organic form of copper (copper nitrite) had better growth and immune response than those fed inorganic form of copper (copper sulfate) sulfate.
