This study was conducted at Research Unit for Animal Behaviour, Menoufia University, Egypt to evaluate the effect of tied or free system on eating and rumination behaviours, stress signs, fecal characteristics, and blood parameters, which could be reflect animal's welfare. Eight Egyptian buffalo heifers were kept in tie-stall barn for four weeks then released from restraints for another four weeks after that tied them for another four weeks up to the end of experiment. Results indicated that, eating time (306.13 min/day) and rumination time (317.93 min/day) were longer in tied heifers than in free animals (178.66 and 306.40 min/day, respectively). The tied animals were acting more stressful than those free; where stepping, kicking and tail movements were more frequently in tied (27.73, 0.80and 115.93 time/day) than in free (16.13, 0.00 and 60.00 time/day respectively). Heifers did not show any aggression (av. Test score 1, 2) in both systems. The position of the ear was backward and down during eating, ruminating, and sleeping, being more obvious in tied animals than in free animals. Total leukocyte count was higher (P<0.05) in free animals (15.26 ×10 3 /uL) than in tied stalls (11.41 ×10 3 /uL). The percentage of undigested components of fecal yield was higher (P<0.05) in free than in tied animals. It could be concluded that the free heifers were more comfortable and in better emotional status. The level of free animals' immunity and their readiness to adapt and face dangers were higher. The tied animals might have a better digestion status.

The purpose of this study was to investigate the effects of adding marjoram leaves extract (MLEx) to growing Japanese quails diets on the gut microbiota, serum parameters, immunity, and growth performance. A total of 320 birds, were randomly assigned to four groups each consisting of four replicates of 20 birds (4 ×4×20). A MLEx-free control diet was given to the first group. The control diet plus 50, 100, and 200 mg of MLEx/kg diet were given to the second, third, and fourth groups, respectively. The study found that the groups fed a diet with 200 mg MLEx/kg diet had the best performance index, body weight, body weight gain, feed conversion ratio and faster growth rate when compared to the control group. Moreover, quails treated with MLEx consumed less feed than control group. With the exception of TG, the group that was fed a diet containing 200 mg of MLEx/kg diet had the lowest numbers of Salmonella, Escherichia coli, lipid profiles, blood glucose and liver enzymes (ALT and AST), with the highest levels of IgG, IgA, IgM and trypsin in comparison to the control group (p < 0.01). Furthermore, quails given 100 mg MLEx/kg diet showed the highest numbers of lactobacilli, amylase, and lipase, while TG and TBARS values were lowest in these birds. To sum up, growth performance, antioxidant activity, serum biochemical and immunity indices, and gastrointestinal bacteria were enhanced by the addition of MLEx at 200 and 100 mg/kg in diets of growing Japanese quails.

The present study aimed to assess the effect of thyme leaf aqueous extract (TLAE) on productive and reproductive performance of Gimmizah chickens. Total of 48 males and 48 females aged 38 wk were divided into three groups (16 of each sex in each) fed on diet (16% CP and ME of 2750 Kcal/kg). Birds in G1 were controls, while those in G2 and G3 were drank water with 2 and 4 ml of 20% TLAE /10 L for 60 days. Results showed that TLAE (4ml) improved (P<0.05) Hb, Ht, glucose, creatinine, and cholesterol in both sexes, basophils in males, albumin and calcium in females. Also, 4 ml-TLAE decreased (P<0.05) plasma AST, ALT, MDA, while increased (P<0.05) T 3 , IgG, IgM, and TAC in both sexes. 4 ml-TLAE increased (P<0.05) weight, tail, width, Haugh unit, and shape of eggs; weight, height, and index of albumen; and height and index of yolk. Sperm motility parameters, morphological features, velocity, and kinetics were increased by 4 ml-TLAE. Also, egg yield, hatched chick weight, and chick-ovo index were increased (P<0.05) by ml-TLAE, while fertility and hatchability of eggs were not affected.In conclusion, thyme administration of thyme in drinking water (4 ml/10 L) can be used to achieve beneficial impacts on reproductive and productive performance of males and females of Gimmizah local strain.

Total of 3380 records from 1635 Friesian cows kept in Sakha and El Karada farms between 1988 and 2020 were utilized to measure their sustainability in performance by estimating the genetic and phenotypic parameters and trends for 305-day milk yield (MY), calving interval (CI), and age at first calving (AFC) . Fixed effects are farm, year of calving – season, and animal parity. The VCE program was used to estimate variance components and genetic parameters. The MY, CI and AFC averages were 3280 kg, 15 mo and 32 mo and their heritability estimates were 0.20, 0.07 and 0.34, respectively. Genetic and phenotypic correlations among the traits ranged from 0.03 to 0.05 and from -0.04 to 0.04, respectively. The corresponding genetic (GT) and phenotypic trends for the studied traits showed deterioration in the overall rates and the ranges of breeding values were from -57 to +105 kg, -0.15 to + 0.25 mo and -0.35 to +0.30 mo for MY, CI and AFC, respectively. Strong intervention in selection and management powers may alter defects by using modern reproductive techniques in breeding programs for future generations. The farm's financial aspects were disturbed by delaying AFC or extending CI. The low CI produced more profit for the farm but prolonging it even for one day caused a financial loss. Also, as AFC expanded, MY increased, but overall farm profits decreased due to the high cost of rearing and replacements after AFC of 24 months
通过估计 305 天产奶量 (MY)、产犊间隔 (CI) 和初产年龄 (AFC) 的遗传和表型参数及趋势，利用 1988 年至 2020 年期间萨哈和卡拉达牧场饲养的 1635 头弗里斯兰奶牛的 3380 份记录来衡量其生产性能的可持续性。固定效应包括牧场、产犊年份、季节和动物奇偶性。VCE 程序用于估计方差成分和遗传参数。MY、CI 和 AFC 的平均值分别为 3280 千克、15 月龄和 32 月龄，其遗传率估计值分别为 0.20、0.07 和 0.34。各性状之间的遗传相关性和表型相关性分别为 0.03 至 0.05 和 -0.04 至 0.04。所研究性状的相应遗传（GT）和表型趋势表明，总体比率下降，MY、CI 和 AFC 的育种值范围分别为 -57 至 +105kg、-0.15 至 + 0.25 mo 和 -0.35 至 +0.30 mo。通过在后代育种计划中使用现代繁殖技术，对选择和管理权力进行强有力的干预可能会改变缺陷。推迟 AFC 或延长 CI 会影响猪场的经济效益。低 CI 可为猪场带来更多利润，但延长 CI 甚至一天都会造成经济损失。此外，随着 AFC 的延长，MY 也在增加，但由于 24 个月 AFC 后饲养和替换成本较高，猪场的总体利润却在下降。

The purpose of the investigation was to determine how adding coriander seed powder affected the broiler chicks' physiological status, blood parameters, microbiological properties, and growth performance as well as carcass characteristics of broiler chickens. A total of 120 One-day-old Avian 48 broiler chickens were divided into four treatment groups, each of which included three replicates. The diet are treatments contained four levels of coriander seed powder (0.0, 3.0, 5.0 and 7.0 %) and lasted for 42 days. The dietary supplementation of coriander seed powder (CSP)did not significantly affect (p > 0.05) growth performance and carcass characteristics of chicks during the whole experiment period compared to control group. However, feeding diets with different levels of CSP had no significant effect on blood serum levels of glucose, total protein, albumin, Uric acid, AST, cholesterol, triglycerides, LDL, HDL, TAC, MDA, immunoglobin G and hematological parameters of broiler chicks. However significantly lower serum levels of ALT were recorded for broilers supplemented with CSP at level 70g/kg compared with other groups. On the other hand, the addition of CSP excreted a notable reduction in the number of coliform bacteria compared to the control group. However, the dietary added CSP led to an increase in the total count compared with the control chicks. The gut morphology characteristics of broiler chicken fed different supplementation levels of CSP are improved compared to the control group. Accordingly, it is concluded that dietary supplementation is beneficial for the productive performance and hematological parameters of broilers.

The present study aimed to evaluate the response of lactating purebred Friesian cows and crossbred Friesian with Baladi cows during hot-humid Egyptian summer conditions to showering. The experimental work was carried out during June – August. Ten Friesian and ten crossbred Friesian × Baladi dairy cows were used and assigned randomly into four treatment groups: two control groups of cows had access only to shade (Friesian cows and crossbred Friesian cows; S), and two groups were provided showers (Friesian cows and crossbred Friesian cows; S + S). The maximum THI throughout the experimental work was 80.43 to 85.22. Showered cows were taken to a holding pen daily to be cooled. Concentrations of TSH, T 3 , T 4 , IGF-1, glucose, cholesterol, triglyceride, total protein, albumin, ALP, Na, K, and milk production were significantly (P<0.01) increased, while, serum cortisol, prolactin, creatinine, AST, ALT and thermoregulatory traits (rectal temperature; RT, respiration and pulse rate (RR; PR), and skin temperature; ST were significantly decreased (P<0.01) in showering than shaded only Friesian and crossbred Friesian cows. Despite crossbred Friesian-Baladi dairy cows displaying more tolerance for heat through attained better parameters for thermoregulatory, endocrinal, and biochemistry and milk production, the amount of improvement of purebred Friesian dairy cows by showering enables cows to express some of their genetic potentials which impeded by the heat stress. Thus, showering can be used to lessen the impact of hot-humid Egyptian summer conditions in the Nile Delta on heat-sensitive exotic purebred dairy cows.

Blocks were prepared with three replacement percentages: 0, 25 and 50% for Diet 1: served as control, Diet 2 , and Diet 3 , respectively. Diets were isocaloric and isonitrogenous with the same roughage concentrate ratio of 30% sugar cane bagasse: 70% concentrate feed blocks. Fifteen Barki male lambs 15.67± 0.30 kg of live body weight (LBW) and 4 months old were divided into three similar groups in a growth trial for 90 days. The results showed that the corn grains revealed a high content of TDN (86.57%), compare with citrus by-product (73.56%). Dry matter consumed was not significantly affected by replacing corn grains with citrus by-product in concentrate feed blocks, almost all digestion coefficients and blood biochemical criteria followed the same pattern, but crude fiber (CF) digestibility were significantly improved by increase the replacement ratio being (65.18, 67.87 and 68.78) for diet 1 , diet 2 and diet 3 respectively. Lambs in diet 1 showed higher ( P ≤ 0.05) final body weight FBW, and microbial nitrogen yield (g) than those fed diet 3. Total body gain and average daily gain followed similar trend. Rumen NH 3-N decreased significantly with the concentrations for diets 1, 2, and 3 being 18.87, 18.02, and 17.83 mg/100 mL, respectively. Overall, results suggest that partial replacement of corn grains with citrus by-products, up to 25% in the multi-nutrient blocks, results nearly similar sheep growth performance with no bad effect on digestion coefficients and blood biochemical.

This study was undertaken to investigate stocking density (SD) and nutrient density (ND) effects on productive performance, egg quality, carcass characteristics, and blood biochemical parameters of Japanese quails. Two hundred eighty-eight quails were randomly divided to 6 experimental groups (each with 4 replications) and kept at three rates of cage SD (277.8, 208.3 and 166.7 cm 2 /bird). Three of these groups were fed on a normal nutrient density diet and the second three groups were fed on a high nutrient density diet (105% of the recommended nutrient requirements for laying quails) and managed similarly from 7 to 19 weeks of age. Carcass characteristics and most blood parameters, certain criteria of productive performance of quails were not affected by SD and ND. Increasing SD impaired EPR, DFI, and DEM of quails. However, increasing ND improved EPR, DFI and DEM but had no effect on all criteria of egg quality. Most egg quality traits were not affected by SD, while YI was deteriorated and ST improved with increasing SD. There were inconsistent differences in serum levels of MDA and COR, but P level increased due to increasing SD. As ND increased serum LDL-C concentration of quails increased while level of uric acid decreased. The SD by ND interactions insignificantly affected all estimated criteria of quail hens. Conclusively, an optimal SD for laying quails is suggested to be 277.8 cm 2 /hen for normal productive performance
本试验旨在研究放养密度(SD)和营养密度(ND)对日本鹌鹑生产性能、蛋品质、胴体特性和血液生化指标的影响。将288只鹌鹑随机分为6个试验组(每组4个重复)，分别以277.8、208.3和166.7 cm 2 /只的笼内SD率饲养。其中3组饲喂正常营养密度饲粮，另外3组饲喂高营养密度饲粮(为产蛋鹌鹑推荐营养需取量的105%)，并从7周龄至19周龄进行类似管理。SD和ND对鹌鹑的胴体特性、大部分血液参数和某些生产性能指标没有影响。增加SD会影响鹌鹑的EPR、DFI和DEM。增加ND可提高EPR、DFI和DEM，但对蛋品质各项指标均无影响。大部分蛋品质的性状不受SD的影响，但随着SD的增加，YI变差，ST提高。血清MDA和COR水平差异不一致，但P水平随SD升高而升高。随着ND的增加，鹌鹑血清LDL-C浓度升高，尿酸水平降低。ND相互作用的SD对鹌鹑蛋鸡各项评价指标影响不显著。综上所述，产蛋鹌鹑正常生产性能的最佳SD值为277.8 cm 2 /只
