    The effects of vitamin B12 (B12) and phosphorus (P) around mating on reproductive performance of ewes have not been investigated previously. Therefore, this study aimed to investigate the effect of injection of a solution (Catosin 10%) contained B12 and P on metabolic status and different aspects of reproductive per-formance of ewes. A total of sixty multiparous Afshari ewes were divided into two groups (n=30 ewes/group) based on age, body condition score (BCS) and body weight (BW). Animals were received either 5 mL of Catosin (B12+P) or 5 mL of sterile water (Control) subcutaneously every 7 days during 28 days before mating and until 7 days after mating. Each mL of Catosin contained 0.05 mg of cyanocobala-min and 100 mg of butaphosphan, which provided 17.3 mg of P in the form of [1-(butylamino)-1-methylethyl]-phosphonic acid. Two weeks after the start of the experiment, the estrus cycles of all ewes were synchronized using intravaginal 12-day CIDRs. Ewes receiving B12 + P had higher BW and BCS at day of CIDR removal and BCS at day 30 after mating (P0.05), whereas, ewes receiving B12+P had higher plasma concentration of B12 at the day of CIDR removal and the day of estrus and mating (P<0.05). The results suggest that B12 + P injection around mating may be an effective strategy for improving repro-ductive performance of ewe. However, further researches need to re-evaluate and confirm these findings. پرونده مقاله

    2 - The Effect of Various Dietary Fibre Sources on Performance, Cecal and Ileal Nutrient Digestibility in Broiler Chickens

    This experiment was conducted to investigate the effects of different sources of insoluble fiber on perform-ance, gastrointestinal tract characteristics, and nutrient digestibility in the broiler's ileum, and cecum. A total of 380-day-old chickens of ross 308 unsexed were arranged into 5 treatments, 4 replicates, and 19 chickens in each, by completely randomized design (CRD). Experimental treatments included 1: control (corn-soybean meal) 2: arbocel (synthetic fiber) 1% in diet, 3: sunflower hulls (3% in diet), 4: soybean hull (3% in diet), 5: processed wheat straw (3%in diet). Observed parameter include: performance (feed intake, feed conversion ratio and body weight gain), gastrointestinal pH, gastrointestinal viscosity and digestibility of dry matter and protein in ileum and cecum and microbial population in ileum and cecum. The results have shown that the inclusion of 3% sunflower hulls in diets leads to the higher average feed intake from 1 to 10 days of age rather than control (P<0.05). In comparison between the ileum and cecum showed that the higher viscosity by Arbocel® in the cecum and the lowest viscosity showed by wheat straw in the ileum (P<0.05). On the other hand, the digestibility of protein and dry matter in the ileum was higher than the cecum (P<0.05). According to the results of this study, it could be noted that all fibers are considered in-soluble fibers and their different behavior in the gastrointestinal tract. The diet Arbocel® has generally led to physicochemical changes (digesta pH and viscosity) and microbial populations. It could be the most im-portant reason for these observations which is related to insoluble fiber particle size and their processing. In addition, reduced dry matter and protein digestibility in the cecum in comparison to the ileum status. Fi-nally, digest pH, viscosity, dry matter and protein digestibility were reduced by insoluble fiber in cecum in comparison to ileum. پرونده مقاله

    3 - Semen Quality, Fertility and Egg Hatchability in Local Turkey Toms Fed Moringa and Gongronema Leaf Powder Diets
    Iranian Journal of Applied Animal Science , شماره 2 , سال 14 , بهار 2024
    The study was conducted to determine the semen quality, fertility and egg hatchability in local Nigeria tur-key toms fed Moringa (MO) and Gongronema leaf (GL) powder diets. A total of 36 (10 weeks) local turkey toms (1.2-1.3 kg) were randomly assigned to 9 dietary treat چکیده کامل
    The study was conducted to determine the semen quality, fertility and egg hatchability in local Nigeria tur-key toms fed Moringa (MO) and Gongronema leaf (GL) powder diets. A total of 36 (10 weeks) local turkey toms (1.2-1.3 kg) were randomly assigned to 9 dietary treatments with 4 replicates of 1 tom each in 3 × 3 factorial arrangement. Also, 72 turkey hens at point of first lay (26 weeks) weighing 3.4-3.5 kg were allot-ted to 9 dietary treatments with 4 replicates of 2 hens each. Treatments include: T1= basal diet (BD) only, T2= BD + 15 g MO + 0 g GL/kg, T3= BD + 30 g MO + 0 g GL/kg, T4= BD +15 g GL + 0 g MO/kg, T5= BD + 30 g GL + 0 g MO/kg, T6= BD + 15 g MO + 15 g GL/kg, T7= BD + 30 g MO +15 g GL/kg, T8= BD + 15 g MO + 30 g GL/kg and T9= BD + 30 g MO + 30 g GL/kg diet. In the main effect of Moringa and Gongronema leaf powder on semen quality, toms fed 30 g MO/kg had the highest (P<0.05) semen quality, while the toms fed 15 and 30 GL/kg had the least (P<0.05) semen quality. In the combined effect of Mor-inga and Gongronema, semen volume, sperm cell concentration and normal sperm cell values of toms on treatment C were the highest (P<0.05), while the toms on treatment C and E had the highest (P<0.05) value for progressive motility. Percentage of fertile and hatched eggs were higher (P<0.05) in 15 and 30 g MO/kg than in control, 15 and 30 g GL/kg. In combined effect of Moringa and Gongronema on % fertility and egg hatchability of tom’s semen, % hatchability caused by semen from toms on treatment C and E were higher (P<0.05) than in the other treatments. It was concluded that improved semen quality in turkey can be achieved using 30 g MO/kg and combination 30 g MO kg + 15 g GL/kg diet. پرونده مقاله
