Alteration of the biophysical and biochemical characteristics of cervical mucus (CM) due to differences in steroid hormones through the estrus cycle leads to different pregnancy rates. This investigation aims to study the possible relationship between CM properties with biochemical profiles, macro-mineral levels, and steroid hormones concentrations, and their effects on pregnancy rates of Egyptian cows. Fourteen Baladi cows were used and synchronized. The model log-likelihood ratio was highly significant (P=0.0009), and reported that the spinnbarkeit (SPK), electrical conductivity (EC), and crystallization (CRS) had significant effect on high pregnancy rate. The 3rd level of SPK (>13.5 cm) and EC (>15 mS/cm) was the highest significant (P=0.0016 & 0.0517, respectively) and a clear positive of estimate marginal effect (20.2543 & 10.6192, respectively) attitude towards the pregnancy rate. However, in case of the CRS, the significant effect was in the first two levels (P=0.0321 & 0.0425, respectively) with a high pregnancy rate, reverse the last 2 levels. Total protein, cholesterol, glucose, potassium, chloride levels, and estradiol concentrations were observed higher with increasing levels of SPK and EC and appearance of typical fern patterns (first two levels of CRS), in contrast to sodium, and progesterone concentrations that decreased with elevating levels of SPK and EC and appearance of atypical fern patterns (last two levels of CRS). There was a close correlation between CM properties and steroid hormones (P4 & E2). So, alterations in CM properties, especially SPK, EC, and CRS, can be utilized to foresee estrus time and, as a result, insemination time.

The current research assessed for dietary desiccated Yucca Schidigera (YS) addition effects on ducks productivity features as well as economical evaluation at summer time. Used 300 Domyati ducks, 26-weeksold (240 females and 60 drakes), that split to egalitarian three empirical groups at random in a completely randomized design. The first one was considered as control and consumed the basal diet; while the second and third empirical groups were consumed the basal diet after adding 150 and 300 mg YS/kg respectively, through 26-37 weeks of age. The results summarized that, ducks fed on both YS levels had superior (p < 0.001) values of egg number and mass, and feed conversion ratio as well as low feed consumed amount compared with those fed the basal diet without any addition through the entire tested period. Spermatozoa concentration and live spermatozoa (%) were (p < 0.001) elevated for drakes fed on 300 mg YS/kg diet, in addition to lower dead sperms (%) than those fed the basal diet. Females fed diet added with YS produced eggs that (p < 0.001) higher in hatching features compared to the control. Adding YS to ducks diet caused a greater haemoglobin, RBC,. Serum total cholesterol, liver ALT and AST enzymes and MDA were significantly attenuated by dietary 300 mg YS/kg. Conclusively, adding 300 mg YS / kg diet produced an advantageous effects of ducks productivity characteristics as well as economical evaluation through summer conditions.

Two trials were conducted with Nile tilapia (Oreochromis niloticus) larvae and fry at the commercial fish hatchery in Fayoum Governorate during 2019. The first was conducted to study the effect of storage conditions for treated feeds with male hormone 17 α –methyltestosterone (17 α –MT), (light condition, store temperature. and time after preparation) on the rates of sex reversal, and growth performance. 5000 newly hatched fry were stocked in a hapa (2×1 m, and a water depth of 80 cm), and were fed with treated feed with 120 mg/kg (17α-MT) for 28 days. No significant difference among treated diets and the ability to sex-reverse fry. The highest sex reversal % was in the treated diets and refrigerated for use at 97.5% and prepared daily at 96.27%. The results of this trial indicate that the rates of male sexual transformation were affected by the method of preparing treated feed hormone, although this effect was limited. The second experiment was performed to study the effect of Tribulus terrestris powder on sexual transformation, compared to the male treated with 17αMT in the same condition as the first experiment. A significant increase (P≤0.05) in percent male was observed with increasing Tribulus terrestris powder in the diets compared to control group. There are significant differences between treatments containing 17α-MT and the basal diet.The results of this trial refer to the recommendation that the Tribulus terrestris powder at 200 g/kg diet and 17α-MT at 150 mg/kg diet are the most effective for sex reversal in Nile tilapia larvae.

Fodder trees such as acacia are rich in antinutritional factors, mainly tannins, which constrain their utilization in animal feeding to fill the gap in feed resources. Rumen microbiota in the grazing and wild ruminant animals can detoxify plants’ secondary metabolites. Therefore, understanding the interaction between plant and rumen microorganisms could improve the fodder plants utilization and reveal antimicrobial-resistant microbial isolates. This study was conducted to get insight into the bacterial colonization and degradation of non-extracted and extracted Acacia saligna in the rumen of three fistulated camels. The findings showed that acacia has a high content of crude protein, fiber, and tannins. Tannins extraction affected the chemical composition and rumen degradation of dry matter, crude protein, and neutral detergent fiber. Furthermore, rumen degradability was increased by prolonging incubation time from 6 to 72 h. The relative abundance of plant-attached bacteria in the camel rumen varied according to tannin extraction. The bacterial community was dominated by phylum Bacteroidetes and Firmicutes and the main bacterial genera were Prevotella, RC9 gut group, Saccharofermentans, Butyrivibrio, Treponema that were affected by tannin extraction. Fibrobacteres showed sensitivity to tannins and some genera such as Alloprevotella, Selenomonas, Pyramidobacter showed resistance to plant tannins, which highlight the camel rumen as an untapped source of tannin-resistant bacteria.

The present study aimed to compare reproductive performance, milk yield, and progesterone profile of Friesian cows diagnosed with late uterine involution (UI), natural early-UI, and those induced to early-UI by oxytocin (OXY). At calving, total of 30 normal multiparous lactating Friesian cows the experimental animals (n=30) were divided into two groups, one group (control, n=20) which were left normally without treatment up to complete UI, and another group (n=10) were i.m injected with 50 IU of OXY within 6-12 hours after parturition. Results showed that mean duration of UI was earlier (P<0.05) in early UI and OXY groups by 22.2 and 18.8% as compared to late UI. Estrus/service rate (ER) increased (P<0.05) in OXY as compared to late-UI, but did not differ significantly in early-UI. Postpartum 1 st estrus PPFEI and service (PPFSI) intervals were shorter (P<0.05) in early-UI than in late-UI and OXY groups. Service period was lower (P≥0.05) in early-UI and OXY than in late-UI groups. Days open was lower (P<0.05) in early-UI than in late-UI. Pregnancy rate (PR) was higher (P<0.05) in early-UI and OXY than in late-UI. Reproductive index was higher in OXY than in late-UI (63.39 vs. 42.33%, P<0.05), and in early-UI than in late-UI (46.99 vs. 42.33%, P≥0.05). Milk production (weekly, daily, and total) was not affected. Early uterine involution naturally in lactating cows or inducing early uterine involution by oxytocin within 24 h of calving have a beneficial effect on the reproductive performance of lactating cows without adverse effect on milk production.
本研究旨在比较诊断为晚期子宫复旧(UI)、自然早期子宫复旧和催产素(OXY)诱导早期子宫复旧的弗里西奶牛的生殖性能、产奶量和黄体酮水平。产犊时，将30头正常产乳的实验动物(n=30)分为两组，一组(对照组，n=20)正常不处理至完全UI，另一组(n=10)在分娩后6-12小时内ig注射50 IU的OXY。结果显示，早期尿失禁组和氧组尿失禁的平均持续时间较晚期尿失禁组分别缩短22.2%和18.8% (P<0.05)。发情/服务率(ER)与ui后期相比显著升高(P<0.05)，但与ui早期相比差异不显著。产后1期发情PPFEI和服务间隔(PPFSI)早期ui组短于晚期ui组和氧组(P<0.05)。早期ui组和OXY组的服务时间均低于晚期ui组(P≥0.05)。采食初期的开放天数低于采食后期(P<0.05)。妊娠率(PR)在妊娠早期和妊娠晚期明显高于妊娠晚期(P<0.05)。缺氧组生殖指数高于尿失速晚期(63.39 vs. 42.33%， P<0.05)，尿失速早期高于尿失速晚期(46.99 vs. 42.33%， P≥0.05)。产奶量(每周、每日和总量)不受影响。泌乳奶牛自然提前子宫复旧或产犊24 h内用催产素诱导子宫早期复旧对泌乳奶牛的繁殖性能有有利影响，但对产奶量没有不利影响。

This education was conducted toward investigate the effect of metformin on ovarian activity and embryo quality of local breed rabbit does. Atotal of 21 mature does were alienated into three groups (7 rabbits in each). Does in the 1group were assumed oral 3ml sterilized saline (Control, G1). Does in the 2 (G2) and 3 (G3)groups were specified 20 and 40 mg metforminm mg /kglive body weight , respectively for 3 weeks before neutral coupling by fertile bucks from the matching breed. Weight and litter size at natal and weaning were documented from 4 does in each group.Embryos being composed by flushing from 3 does in each group with phosphate buffer solution from oviduct and uterine horn in each doe in all groups after 72 hrs of mating, where the ovaries structure on the ovarian site was recorded. Inconsequential contrasts between location of the ovary within the cruel number of little, medium and large follicles. Whereas, the cruel number of CL and bleeding follicles in right were altogether (P<0.05) higher than cleared out (5.78 vs. 4.11) and (1.22 vs. 0.67). The rate of practical embryos was higher in G1 (95.2%, P<0.05) than those in G2 (88.9%) and in G3 (75.0%). Whereas fetus recuperation rate was higher in G2 than in other bunches, but the adjustments among them were not noteworthy. These results indicated that treatment improved ovarian response and reproductive performance although it's reducing embryo recovery and viability rate for rabbit does.

This study was designed to study the effects of stocking density without or with yeast extracts supplementation on productive and reproductive performance, digestive enzymes, blood biochemical parameters, and antioxidant and immune measurements of quail breeders. A total number of 336 Japanese quail birds at 8 weeks old were used. Quails were randomly distributed into 6 groups and 4 replicates maintained / each group in a complete randomized design. The 1 group contained 36 birds (24 females and 12 males) was stocked at a rate of 9 birds /replicate (control, ND; 36 quails/m) and fed the basal diet without any supplementation; the 2, 3, 4, 5 and 6 groups contained 60 quails (40 females and 20 males) and stoked at a rate of 15 chicks/replicate (HD; 60 quails/m) and fed on a basal diet supplemented with 0, 1, 2, 3 and 4 mg YE /kg diet, respectively. Egg number, egg weight and egg mass were significantly decreased (P<.0001) due to increasing stocking density from ND (9/cage) to HD (15/cage) and fed without dietary YE supplementation. The activity of SOD (p<0.0001), TAC (p<0.0001) and GPX (p=0.0047) was improved with HD plus YE when compared to HD. Digestive enzymes (amylase, lipase, and protease) activity was decreased with HD when compared to ND. It could be concluded that addition of yeast extract can positively mitigate the stress applied to quail raised under high stoking density by enhancing productive and reproductive performance, lipid profile, antioxidants and immunity as well as egg quality criteria.
本试验旨在研究饲养密度对鹌鹑生产性能、繁殖性能、消化酶、血液生化指标、抗氧化和免疫指标的影响。试验共选用8周龄日本鹌鹑336只。采用完全随机设计，将鹌鹑随机分为6组，每组维持4个重复。1组36只(雌鸟24只，雄鸟12只)，按9只/重复放养(对照，ND;36只/m)，饲喂基础饲粮，不添加任何添加剂;2、3、4、5和6组60只鹌鹑(雌性40只，雄性20只)，饲养率为15只/重复(HD);60只/m)，分别在基础饲粮中添加0、1、2、3和4 mg YE /kg饲粮。饲养密度由低密度(9只/笼)增加至高密度(15只/笼)，且饲粮中不添加YE，蛋数、蛋重和蛋质量显著降低(P< 0.0001)。与HD相比，HD + YE提高了SOD (p<0.0001)、TAC (p<0.0001)和GPX (p=0.0047)的活性。与ND相比，HD患者消化酶(淀粉酶、脂肪酶和蛋白酶)活性降低。由此可见，添加酵母浸膏可以通过提高鹌鹑的生产性能和繁殖性能、血脂、抗氧化剂和免疫力以及蛋品质标准，积极缓解高饲养密度条件下鹌鹑的应激。

The objective of this study was to evaluate the effect of low protein diet fortified with 0.2% glycine (gly) on Mandarah a native Egyptian strain chick’s growth performance, carcass, small intestinal morphology, shank and keel bone length, blood parameters, growth hormone and blood antioxidant status during starter and growing periods (from 1 day to 12 weeks of age). A total number of 135 one day old Mandarah chicks were randomly divided into 3 equal groups with 3 equal replicates each. Control group (C) was fed normal crude protein diets (19% CP as starter and 17% CP for grower), group 2 (LP1) and 3 (LP2) fed 1.5 and 3% less crude protein respectively, than control supplemented with 0.2% glycine. Results indicated that LP1diet supplementation with glycine led to significant improvement in body weight (BW) during the starter period, and in feed conversion ratio (FCR) during the first 4 weeks of age. However, LP2+gly group recorded the lowest BW at 12 weeks of age, while recorded significantly better relative weights of carcass, liver, gizzard and spleen. Results also showed no significant differences in shank and keel length, goblet cell number, villi height, crypt depth, blood total antioxidant capacity, glutathione and all blood biochemical parameters. Glycine supplemented groups recorded significantly higher growth hormone values and lower litter moisture and litter nitrogen values. In conclusion adding glycine 0.2% to low protein diet (1.5% reduction) improve growth performance and litter quality of Mandarah local Egyptian strain during starter and grower periods.

Sixty non-pregnant Rahmani x Romanov crossbred ewes used to study the effect of selenium on production and reproduction performance of ewes. The experimental ewes divided into five similar groups based on age, body weight, and physiological state (12 head/group), the first group (G1) used as control group without any addition. The second and third groups were injected with 0.1 mg (G2) or 0.2 mg/kg DM (G3) of selenium (sodium selenite), or oral of 0.1(G4) or 0.2 mg/kg DM (G5) of nano selenium. Fertility (%) of pregnant ewes were 83.3, 91.7, 100, 91.7 and 100% in G1, G2, G3, G4 and G5, respectively. Total protein (g/dl) blood were 7.1, 6.06, 6.4, 5.9 and 6.1 for G1, G2, G3, G4 and G5, respectively and corresponding values of globulin (g/dl) were 2.22, 2.54, 2.40, 2.05 and 2.38. The values of GOT were 79.2, 60.25, 69.07, 79.2 and 60.25 (U/L) and the values of GPT were 28.71, 15.61, 12.2, 16.5 and 20.6 (U/L). Thyroid hormones as T3 and T4 were 3.2, 4.2, 4.1, 4.36 and 4.65 (ng/ml) for T3 and 6.7, 6.6, 7.09, 6.84 and 7.33 (ng/ml) for T4 on G1, G2, G3, G4 and G5. The present study showed that giving Se to pregnant ewes improved the immunity of their lambs during the suckling period.. Finally, it can conclude that used of 0.1 or 0.2 mg/kg oral Nanoselenium could favorable effects on lambs performance.

Objective was to investigate supplying goats by bee bread (BB) such as natural hive pellets or extract to improve reproductive and productive performance. A total number of 24 goats were used. They were divided into three groups as A, B and C then, BB offered at levels of 0, 4 g and 5.0 ml daily / head, respectively. Reproductive parameters and oestrus resumption were investigated. Also, productive performance such as suckling and peak lactation were determined. The blood parameters were analyzed. Finely, correlation coefficient among feeding and some reproductive and productive procedures were explained. The results indicated that B or C goats had higher (P<0.05) and similar LBW, BCS and BMI than A goats. The reproductive parameters were better in B and C goats than A goats. The B and C goats have shorter (P<0.05) days of estrus and longer (P<0.05) estrus time duration than A goats. Milk yield during suckling and peak of lactation were significantly (P<0.05) higher in B and C goats than A goats. The glucose, total protein, globulin, HDL were significantly (P<0.05) higher in B and C goats than A goats. However, the total lipids, albumin, triglycerides, cholesterol, LDL, AST, ALT and creatinine, in B and C goats were lower (P<0.05) than A goats.
