Department of Animal Science and Technology, Federal University of Technology Owerri, Imo State, Nigeria The objectives of the study were to investigate the socio-cultural, herd structure and reproductive practices of pastoralist cattle producers in Nigeria. The study was carried out with the aid questionnaires, oral interview and field observations on 300 respondents spread across the three study LGAs. Pastoral cattle production in Adamawa state was predominated by highly experienced (80 – 85%), married (75 - 88%), male (75 – 90%) Fulani (95 – 65%) Muslims (75 – 80%) aged mostly 31 – 40 years (48 – 55%) and having limited western education. White Fulani (50.00%) was the most common breed in Gombi LGA, while Red Bororo (53.00%) and Adamawa Gudali (50.00%) were the most predominant breeds in Mubi North and Jada LGAs respectively. Most of the pastoralist (40 – 50%) maintained herd size of 41 to 50 heads and reared cattle for multiple purposes such as breeding, milk, meat and traction. Farmers practiced uncontrolled breeding, with bull to cow ratio of 1:10 (75.00% at Mubi north LGA). First mating (50 – 60%) was done between 4 and 5 years, while age at first calving (73 -75%) was mostly 5 – 7 years indicating serious reproductive life wastage. Most pastoralists (55 – 65%) use ethno-veterinary practices to enhance cattle reproductive performance. Calving rates (75 – 85%) were more during late rainy season (LRS), while (90.00%) depended on natural pastures for feeding their cattle. Cattle graze ...

Reproductive Performance of Zebu Cattle Following Artificial Insemination (AI) in Adamawa State, North-Eastern Nigeria

Research Article of International Journal of Animal Research Reproductive Performance of Zebu Cattle Following Artificial Insemination (AI) in Adamawa State, North-Eastern Nigeria Kubkomawa, H. I., Abubakar, S. N. and Adamu, M. S. Department of Animal Production and Health, Federal Polytechnic, Pmb 35, Mubi, Adamawa State, Nigeria The precarious supply of animal products to Nigerian populace may worsen if livestock production is still based on the use of multipurpose indigenous cattle breeds with genetically low productive potentials. The main objective of this study was to determine the reproductive performance of Zebu cattle in an AI program in The Federal Polytechnic Mubi, Livestock Farm, Adamawa State, North-Eastern Nigeria. Twenty (20) female Zebu cattle comprising heifers and cows were selected at random from the cattle herds, February to March, 2016. The insemination was performed via recto-vaginal technique following estrus synchronization, using prostaglandin F2α (PGF2α). The results of the study showed animal age ranging from three (3) to ten (10) years old with parity from 0 to 5. The body condition scores of the animals vary from 2.0 to 2.5 indicating poor nutrition and management practices at the period. There was 100% estrus detection rate since all animals displayed signs of heat and were turned in for insemination. The findings showed a low success rate of 25% with higher failure rate of 75%. It was concluded that, Ayrshire and Brahman crossed Zebu female cattle through AI, though gave low fertility rates at the first attempt, is still the rapid means of improving milk production and reproductive efficiency of the combined adaptability and hardiness of the Zebu cattle (Bos indicus) with the genetically high reproductive and milk yield potentials of the exotic breeds (Bos taurus). There is still room for an in-depth future study of the effects of upgrading indigenous Zebu cattle crossed with exotic ...

Is L-arginine or glucose dependence required for fetal growth, survival and maternal progesterone during late pregnancy in ewes?

Research Article of International Journal of Animal Research Is L-arginine or glucose dependence required for fetal growth, survival and maternal progesterone during late pregnancy in ewes? M. M. Zeitoun Department of Animal Production and Breeding, College of Agriculture and Veterinary Medicine, P.O. Box 6622, Qassim University 51452, KSA This study aimed at investigating effects of drenching low and high dosage of L-arginine alone, combined with propylene glycol or propylene glycol alone during the eight weeks during late ewe's gestation on the litter weight and survival at birth and maternal progesterone (P4). Thirty four adult Najdi ewes were randomly allotted into six groups (G). G1 (C, control, n=6) ewes orally given 50 ml physiological saline daily, G2 (LA, n=6) ewes given 50 ml containing 37.5 mg L-arginine/kg/day, G3 (HA, N=6) ewes given 50 ml containing 75 mg l-arginine/kg/day, G4 (P, n=6) ewes given 50 ml propylene glycol, G5 (LAP, n=5) ewes given 50 ml containing 25 ml propylene glycol and 25 ml LA and G6 (HAP, n=5) ewes given 50 ml containing 25 ml propylene glycol and 25 ml HA. Jugular blood samples for serum P4 were collected once a week from the beginning of treatment till parturition. At parturition litter size, litter weight, neonatal birth weight and viability were determined. Mean lamb birth weight was 3.75, 5.44, 5.72, 5.75, 7.33 and 5.6 kg in C, LA, HA, P, LAP and HAP, respectively. Survival rates at birth were 75, 87.5, 100, 83.3, 83.3 and 100% in C, LA, HA, P, LAP and HAP, respectively. The highest P4 level with typical profile was found in LAP ewes. In conclusion, administration of a combination of l-arginine (37.5 mg/kg/d) with propylene glycol during eight weeks of late sheep pregnancy not only enhanced fetal growth and survival of neonates but it also enhanced maternal corpus ...
