The present study aims to assess different levels of parsley on the performance of broilers. The number of commercial broiler chicks (Ross 308) was 120 day old, randomly divided into 5 treatments with 3 replicates, meaning that each treatment had 24 chicks over a 6 week period. T1 was a control group whose diet level was lack of supplements (core diet). However, other T2, T3, T4 and T5 treatments included supplementing parsley at the level of 3, 6, 9 and 12 g/kg respectively. As part of the growth performance parameter at the end of the experiment, 4 chickens were slaughtered to estimate carcass and muscle characteristics. Therefore, the use of parsley at the rate of 9 g/kg had a significant influence on body weight and body weight gain. Efficiency of feed conversion and feed intake improved numerically compared to the control group throughout the study period. The highest thigh and carcass weights were obtained at a parsley feed level of 9 g/kg and there was no difference between treatments for animal weight, percent dressing. and the wing. In addition, there was no significant difference (P<0.05) in organ weights between the different treatments.

The aim of this study was to assess the effects of the slicing and puncture process and CL-bearing on the recovery and efficiency of oocytes from sheep ovaries. In the present study, 100 ovaries with corpus luteum (CL+) and without corpus luteum (CL-) were used. Ovaries weight, length, width, and thickness were measured. Using the slicing and puncture methods, the follicles were counted. The follicles were grouped in small follicles (< 2 mm), medium follicles (2-5 mm), and large follicles (> 5 mm). Oocytes have been categorized as compact cumulus / oocyte complexes (COCs), expanded (EXO), partially denuded (PDO), denuded (DO), and degenerated (DEG) oocytes according to their morphology. Our results revealed that the average weight of sheep ovaries CL+ (0.868 g) were significantly (P>0.05) greater than ovaries CL- 0.727 g, but there were no significant differences in length or width. The average number of total and compact oocytes/ovary when slicing was significantly (P>0.05) higher than puncture techniques were used (6.87 vs. 5.70) and (3.39 vs. 2.46), respectively. CL+ ovaries showed insignificantly (P<0.05) lower oocyte recovery rate in total, compact (COCs) and denuded oocytes, while the opposite of this trend in partial denuded and degenerated oocytes as compared to CL- ovaries. In conclusion, the cumulus-oocyte complexes obtained from sheep ovaries without CL and from the slicing rather than puncture method can be used for in vitro embryo production of sheep.
本研究的目的是评估切片穿刺过程和含氯对绵羊卵巢卵母细胞恢复和效率的影响。本研究采用有黄体(CL+)和无黄体(CL-)卵巢各100个。测量卵巢的重量、长度、宽度和厚度。采用切片法和穿刺法对卵泡进行计数。卵泡分为小卵泡(< 2 mm)、中卵泡(2-5 mm)和大卵泡(> 5 mm)。卵母细胞根据形态可分为致密卵丘/卵母细胞复合物(COCs)、扩张卵母细胞(EXO)、部分脱落卵母细胞(PDO)、脱落卵母细胞(DO)和退化卵母细胞(DEG)。结果表明，绵羊卵巢CL+ (0.868 g)的平均重量显著(P>0.05)大于CL- (0.727 g)，但长度和宽度无显著差异。切片时卵巢总卵母细胞数(6.87 vs. 5.70)和致密卵母细胞数(3.39 vs. 2.46)均显著高于穿刺法(P>0.05)。与CL-卵巢相比，CL+卵巢的全卵母细胞、致密卵母细胞和脱脱卵母细胞的卵母细胞恢复率均不显著(P<0.05)降低，而部分脱脱卵母细胞和变性卵母细胞的恢复率则相反。综上所述，采用切片法而非穿刺法从绵羊卵巢中获得的卵母细胞-卵母细胞复合物可用于绵羊体外胚胎生产。

The objective of this study is to characterize the prevailing production system of raising camels in Marsa-Matrouh governorate in Egypt. A semi-structured questionnaire was designed to collect the required data randomly from 58 respondents in four regions, during the year 2020/2021. The questionnaire contains socioeconomic characteristics, herd size, management practices, milk production, reproduction performance, birth and weaning weights, and the main constraints. The obtained results showed that more than 95% of the camel's breeders were illiterate or barely read and write. Their main job is farming. Most of the breeders were landowners. The majority of the breeders are raising sheep, goats, and poultry besides camels. All camel breeders are applying natural mating. The average age of the camel at first calving was 5.5 years, and days open were 56.4 days. Calving interval ranged from 20.8 to 22.1 months. Daily milk yield was ranged from 5-10kg/head, and lactation period was around 9 months. The average birth weight for both female and male calves was 30kg and 35kg, respectively. Camel calves are weaned at about 145kg and 7 months age. The main constraints facing camel breeders were increasing feeding costs, water shortage, poor pasture, and poor veterinary care.The study concluded that camels play an important role for the people living in the harsh climate. Camel breeders are facing many problems which affect camel productivity and reflect on their economic livelihood. Proper and prompt moving is badly needed to optimize performance and achieve efficient camel production and economic return.

Two hundred and ten unsexed one day old Cobb 500 broiler chicks were used until 6 weeks of age to study the effect of Trichoderma reesei fungus (10 8 CFU /ml)and sodium hydroxide(NaOH, 10 g/kg OPM)addition in olive pulp meal(OPM)broiler diets on growth rate, digestion coefficients, some blood parameters, carcass traits and the economic efficiency of feed. The chicks were randomly distributed into seven equal treatments, 30 chicks/treatment with three replicates each. The treatments were control, C (The basal diet without OPM),T1(Basal diet+12% OPM),T2 (Basal diet +12% OPM+fungus), T3 (Basal diet+12% OPM+NaOH), T4 (Basal diet +15% OPM), T5 (Basal diet + 15% OPM + fungus) and T6 (Basal diet + 15% OPM + NaOH). The treated OPM with NaOH showed similar results of body weight and gain as the control .The control treatment recorded the highest value(P<0.01)of feed intake. The best value (P<0.05) of feed conversion ratio was noticed with T3. The treated OPM showed a significant (P<0.05) in CP, CF, NFE, DCP, TDN (%) and ME(kcal/kg)compared to the untreated OPM; The treated and untreated OPM increased plasma cholesterol, LDL and HDL levels, While Triglycerides were decreased with all treatments compared to the control. All treatments recorded high values (P<0.05) of gizzard (%), cecum weight and cecum length compared to the control , the treated and untreated OPM decreased the feed cost/kg meat and increased the net return/kg meat.The results concluded that treating OPM with NaOH or fungus improved the nutritive value of OPM without any adverse effects on birds.

The aim of this study was to determine goat breed (Zaraibi and Baladi) or buck age (young and old) effect on characteristics, production, flow cytometer, DNA fragmentation and comet assay parameters of spermatozoa. Twelve Baladi (BG) and Zaraibi (ZG) bucks, 3 old (2-4 years) and 3 young (8-12 months) from BG or ZG used for semen collection for 24 weeks. Volume (EV), sperm progressive motility (PM), livability (LS), abnormality (SA), and concentration (SCC) were evaluated, sperm outputs (SO) were calculated. Sperm apoptosis, DNA fragmentation and comet assay were analyzed. Results revealed that PM, LS, SA, SCC, total, motile, live, normal, and functional SO per ejaculate were significantly higher in ZG than BG and in old than young bucks in each breed. Both EV and LS were significantly higher, while SCC was significantly lower in old than young ZG. Each of EV, PM, and SCC was significantly higher, while SA was significantly lower in old than young BG. Viable sperm, haploid and cell cycle percent was significantly higher, while early apoptotic, apoptotic, and necrotic spermatozoa percent was significantly lower in old than young bucks of each breed. Spermatid percent in ZG and diploid percent in BG were significantly higher in old than young bucks. Tailed sperm, tail length, tail DNA percentage, and tail moment were significantly lower in ZG than BG, and in old than young bucks of each breed. It can be stated that Zaraibi bucks has a good potential for semen production than Baladi breed.

The udders were followed by monthly observation and measurement starting from the day of mating (Dm = 0d) in 13 pregnant Maghrebi she-camels. They were classified according to the multiple parities into three classes (1-2 parities), (3-4 parities) and (5-6 parities). These measurements included: udder length, udder horizontal circumference, udder semi-vertical circumference, udder depth, udder size, udder height, teat length, teat diameter, and distance between teats. In all different udder measurements, the differences were ascending, from (1-2 parities) to (5-6 parities). Those differences varied between significant and nonsignificant according to the convergence between the multiple parities classes. The measurements did not agree with each other on a constant rate of increase in growth rates. Each measure differed from the rest of the measurements in its rates of increase between multiple parities classes. The differences were very clear in some of the measurements, while they diminished in others. No significant increase was observed in udder measurements during gestation, which were divided into five stages. The results of the study indicated that the effect the multiple parities in the Maghrebi she-camels had a significant impact on the udder measurements of all Types, much greater than the effect of the stages of one gestation on those measurements.

This work aimed to study the effects of extenders containing sugar (300and 370-mM glucose) on the storability and fertility of turkey semen. Semen was collected twice a week from 12 Bronze turkey toms of 40 wk old by abdominal massage for 4 wk. The collected semen of toms was pooled, mixed and extended at a rate of 1:2 with saline (E1), tris-eggyolk-300 mM glucose (E2), and tris-eggyolk-370 mM glucose (E3). After dilution, semen was stored for 96 hours at cool temperature (4-5C). Semen was evaluated for motility, normality, and kinetic parameters of spermatozoa, then sperm fertility was determined for semen stored for appropriate storage time for each extender. Results show that overall mean of all sperm motility variables (total motility, total progressive, rapid and slow progressive, and non-progressive motility, and immotile spermatozoa), sperm-morphological parameters (head and neck abnormalities, mono and dual deformations, and sperm deformity index, SDI), and sperm-dynamic parameters (VCL, VSL, VAP linearity, straightness, and wobble) were improved by E2 and E3 as compared to E1. The fertility rate was higher (89.5%) for eggs produced from hens inseminated with E3-semen stored for 72 h (P<0.05) as compared to E1-semen stored for 2 h (77.5%), but E2-semen (85.83%) showed insignificant differences with both E1 and E3. Semen of toms could be stored with maintaining sperm function and fertility in tris-glucose-based extender for 72 h.

The aim of this study was to undertake the relationship between body weight and linear body measurement traits in three different chicks' strains, as well as to develop some regression equations to estimate body weight from linear body measurement. A total of 600 chicks (200 each from Fayomi (F), Golden Sabahia (GS) and White Leghorn (WL)) were used for this research. Result showed that males of the three strains were significantly higher body weight (bw) and other body measurements. Comparison of three strains also showed that GS bird was significantly better than F and WL birds for all traits under study. Lower correlation value was obtained between BW and back length (BL) and significant in male WL strain at 8 weeks old. At 12 weeks old, high, positive and significant values were observed between BW and circumference breast (CB) in female WL strain. A stepwise multiple regression analysis revealed that BW was best predicted using shank length (SL), keel length (KL), CB, BL for male WL, SL, CB, BL for female WL, GS and male F. Meanwhile, BW was best predicted using SL and CB for male GS. It was concluded that breed differences do exist between the strains under study and some of body measurements can be used as accurate indicators to improve body weight. Therefore, breeding programs designed for genetic improvement of body weight in the population of Leghorn, Golden Sabahia and Fayoumi chicks can use selection of different body measurements as selection criteria.
