This study was aimed at investigating the effects of breed, age, body condition score, and nutritional status on follicular dynamics, quality, and oocyte yield in Cameroonian zebus cattleBos indicus(Gudali and Red and White Fulani). A total of 95 cows were investigated for breed, age, body condition score, and nutritional status. Blood samples and ovaries of these cows were collected during slaughtering. Follicles on each ovary were counted and measured using electronic digital calipers and then classified into three categories: small (<3 mm), medium (3 – 8 mm), and large (> 8 mm) diameter. The oocytes were retrieved by slicing each ovary into a Petri dish containing collected medium. The oocytes recovered were examined under a stereoscope (x 10) and classified into four groups based on the morphology of cumulus oophorus cells and cytoplasmic changes. From these ovaries, 3888 follicles were counted with an average population of 27.81 ± 6.88 follicles per cow. The average numbers of small, medium, and large follicles per cow were 17.26 ± 1.36 (62.06%), 9.64 ± 1.00 (34.66%), and 0.52 ± 0.32 (1.86%), respectively. A total of 1822 oocytes were harvested with an average of 19.11 ± 0.89 oocytes per cow. Oocytes graded I, II, III, and IV were 7.03 ± 2.30 (36.65%), 4.53± 2.01 (23.61%), 3.19 ± 0.85 (16.63%), and 4.43 ±1.62 (23.09%), respectively. This study also showed that ovarian weight, number of follicles, and oocytes’ yield of right ovary were higher than left ones (P < 0.05). Younger and normal cows (BCS = 3) presented higher (P < 0.05) number of follicles and oocytes. Urea and cholesterol levels were higher in Gudali and White Fulani cows (P < 0.05). This study indicated that ovaries of zebus harvested in slaughterhouse are an important source of follicular population, oocytes yield, and quality. Right ovaries are heavy and offer more numbers of follicles and oocytes than the left ones. BCS is the best indicator of nutritional status of cows. Important follicle populations are obtained from cows aging 6-9 years with BCS = 3.

Pelvic Size

Post-weaning growth and body condition, puberty and pelvic size of 197 heifers comprising straightbred Hereford (HxH) and Brahman (BxB), first-cross (BxH) and back-cross (HxBH and BxBH) heifers were evaluated. The heifers were born over a 3 year period, and grazed improved and semi-improved pastures following weaning at Grafton, New South Wales. Prior to weaning, heifers had been reared by dams on three pasture systems (high, medium and low quality pastures). Heifers from low quality pre-weaning pasture had higher (P < 0.05) post-weaning liveweight gain than those from high and medium quality pastures. BxH heifers gained 71 g/day more (P < 0.05) than the mean gain of their contemporaries of the other genotypes, whose gains were similar, from weaning to either 26 or to 30 months of age. Liveweight at all ages was influenced by genotype x pre-weaning pasture system interaction. At 30 months of age, BxH heifers from high and medium pre-weaning pastures were the heaviest. At the same age, but from low quality pre-weaning pasture, heifers with crossbred dams (HxBH and BxBH) were the heaviest. Wither height depended significantly (P < 0.05) on the proportion of Bos indicus genes, increasing from 113.8 cm in the HxH heifers to 124.4 cm in the BxB heifers at 30 months of age. BxH heifers had a higher (P < 0.05) body condition score than their contemporaries of the other genotypes, which were in similar condition, at 26 and 30 months of age. On average (across pre-weaning pasture system), 9% of BxB heifers had reached puberty by 22 months of age compared to 62, 95, 82 and 64% (s.e.= 9) for HxH, HxBH, BxH and BxBH heifers respectively. No significant genotype differences were obtained in the height, width and size of the pelvic opening of the heifers, measured just prior to the beginning of the mating season at 26 months of age.

Thirty goats of the breeds Czech Brown Shorthaired and Czech White Shorthaired and their crosses were randomly selected from a flock at a farm in the Czech Republic. All animals were monitored for one year at monthly intervals for their nutritional status (live weight, LW; body-condition score, BCS; depth of musculus longissimus thoracis et lumborum, MLTL; back-fat thickness, BT) and infection intensity with Eimeria sp. (EIM) and strongylid nematodes (STR). Regression–correlation analysis showed a possible interrelation of BCS with EIM infection. Analysis of muscle and fat reserves indicated that BT was better than MLTL in identifying EIM infection. Goat nutritional status was not significantly correlated with STR infection. A linear tendency (p = 0.092), however, was detected for the response of MLTL to STR infection. Results of this study indicated theoretical use of BCS for Eimeria identification and suggested some perspective of BCS for targeting animals infected by strongylid nematode. Validity of our results, however, was limited by number of observed animals managed under specific breeding conditions.

Liver Flukes

Fasciola, Fascioloides, and Dicrocoelium cause liver fluke diseases in ruminants and are of zoonotic and economic importance. This cross-sectional study aimed to determine the prevalence of liver fluke egg infection in White Fulani Cattle slaughtered in Wukari Cattle market abattoir in Wukari, Taraba State. A total of 262 gallbladders were collected and their contents were analyzed for the presence of eggs of liver flukes using sedimentation technique. Descriptive analysis was done using SPSS version 20 for window and Pearson’s Chi-Square (χ2) was used to evaluate the association between variables. Fasciola and Dicrocoelium eggs were encountered. Only 74 (28.2%) samples were positive for Fasciola egg and 211 (80.5%) for Dicrocoelium. The prevalence of liver fluke infection revealed 25% and 28.6% Fasciola eggs for male and female animals, respectively, while lancet fluke had 83.3% for male and 80.3% for female. Fasciola eggs were recovered in 20.8% of animals aged less 3 years (<3yrs) and 29.9% was recorded in animals 3 years and above (≥ 3yrs) while 81.3% for animals ≥ 3yrs and 77.1% for animals <3yrs were recorded for Dicrocoelium eggs. The body condition score-based prevalence for Fasciola yielded 38.1%, 26.8%, and 14% for poor, average, and good, respectively, while Dicrocoelium yielded 85.7%, 79.3%, and 85.7%. There was a significant difference between the body condition scores for fasciolosis. Only 59% harboured single infection with eggs of Dicrocoelium (P< 0.05) while 6.9% harboured Fasciola eggs. Mixed infection associating Fasciola and Dicrocoelium was observed in 21.4% of the sample cattle. Liver fluke infections: fasciolosis and dicrocoeliosis occur among White Fulani cattle in Wukari and these infections are associated with the body condition score of the animals. This greatly affects the cattle production. There is a need to institute adequate control programmes complemented with good well-planned management practices in any production system involving cattle in Wukari.

The Impact

This study evaluated the impact of nutritional status of Morada Nova sheep at lambing on the reproductive and productive performance and on the survival of lambs in early weaning system. Nineteen, Morada Nova sheep were assigned to two groups according to body condition score (BCS) at lambing: low BCS (n = 11) and high BCS (n=8) with body condition respectively of (mean ± SD) 2.0 ± 0.3 e 2.9 ± 0.1. From birth until lamb weaning (45 days), sheep were weighed weekly and checked the BCS, loin subcutaneous fat thickness, loin depth, hematological profile, milk composition and production, and every three days, we measured the uterine diameter. Lamb weightings were performed up to one week after weaning (52 days). The lower availability of muscle and fat reserves in the low BCS group negatively affected milk production and consequently performance of suckling lambs. However, the results indicated that the uterine involution process, the reproductive parameters including prolificacy, rate of multiple births, number of white blood cells, milk quality, body weight of lambs at birth and mortality rates were not affected by the body condition. The results allowed to describe the responsiveness to opposite nutritional status of Morada Nova sheep, showing their characteristics of adaptation.

Body condition score is very critical during breeding, lambing and lactation, the current study was conducted to assess the repeatability and reproducibility of body condition score inYankasa sheep in some selected Local Government Areas of Kano State, Nigeria; Bebeji (BBJ), Dawakin Kudu (DKD), Wudil (WDL), Shanono (SNN), and Dambatta (DBT). Multistage sampling was adopted to select a total of 300 sheep comrison of 99 rams and 201 ewes. Body condition score was determined twice a day by two assessors using the standard procedure. The experiment was conducted using a cross factor design. Model III analysis of variance was carried out to determine the between sheep and inter and intra-assessor variations in the trait. The results shows a significant (P<0.01) effects of rams and ewes on the body condition score.It is concluded that repeatability and reproducibility of BCS were very high (0.828-0.982 and 0.791-0.939 for repeatability and reproducibility, respectively). It is recommended that sheep farmers consider condition scores in the selection and routinely assess their animals' nutritional status.     Le score de l'état corporel est très critique pendant la reproduction, l'agnelage et la lactation, la présente étude a été menée pour évaluer la répétabilité et la reproductibilité du score de l'état corporel chez les moutons de Yankasa dans certaines zones de gouvernement local sélectionnées de l'État de Kano, au Nigeria; Bebeji (BBJ), Dawakin Kudu (DKD), Wudil (WDL), Shanono (SNN) et Dambatta (DBT). Un échantillonnage à plusieurs degrés a été adopté pour sélectionner un total de 300 moutons de 99 béliers et 201 brebis. Le score de l'état corporel a été déterminé deux fois par jour par deux évaluateurs en utilisant la procédure standard. L'expérience a été menée en utilisant une conception à facteurs croisés. Une analyse de la variance du modèle III a été effectuée pour déterminer les variations entre les moutons et les variations inter et intra-évaluateur du caractère. Les résultats montrent un effet significatif (P <0.01) des béliers et des brebis sur le score de l'état corporel. Il est conclu que la répétabilité et la reproductibilité du BCS étaient très élevées (0.828-0.982 et 0.791- 0.939 pour la répétabilité et la reproductibilité, respectivement). Il est recommandé aux éleveurs de moutons de prendre en compte les scores de condition dans la sélection et d'évaluer régulièrement l'état nutritionnel de leurs animaux.

During the period of year (representing spring, summer, autumn, and winter) Jennies at Giza Zoo abattoir were checked for body condition score (from 1 to 5), age (1 to 7 years; 8 to 14 years; and >15 years old). After culling, ovaries of 377 Jennies were collected, two ovaries were weighed, and the number and size of ovarian follicles were recorded. Cumulus-Oocyte Complexes (COCs) were collected after the ovarian follicles have been sliced and scraped, and COCs number and quality were determined. Data indicated that right and left ovaries and overall ovarian weight were significantly increased (P<0.05) in summer than the other seasons. The number of small size ovarian follicles was decreased (P<0.05) in spring than other seasons, while oocytes number and quality were not significantly affected by season. Jennies of 1 to 7 years old showed a significant (P<0.05) smaller left ovary and total ovarian weight than the two other groups. Jennies of 8-14 years old) have a significant high (P<0.05) small size and a whole number of ovarian follicles than the other groups. Jennies with BCS-3 possess a significantly (P<0.05) higher total ovarian weight, total number of ovarian follicles and the total number of COCs recovered than BCS-1 or BCS-4. While the BCS-4 group showed the lowest (P<0.05) number of ovarian follicles and produced less (P<0.05) number of COCs than the other groups. Conclusion: In Egyptian Jennies, ovarian activity was affected by season, BCS and age of the animal, while, COCs yield and quality were more affected by BCS.

Timed Artificial Insemination

Induction of ovulation for timed artificial insemination (TAI) with the Ovsynch protocol was evaluated in 49 anoestrous and lactating Bos taurus × Bos indicus cows. Palpation per rectum and transrectal ultrasonography were used on Days -30, -20, -10 and 0 (start of treatment) to confirm anoestrus but with the presence of follicles = 10 mm, and every other day during treatment to determine ovarian activity. Cows were randomly assigned to: (1) Ovsynch (n = 24; Day 0, 200 µg GnRH; Day 7, 150 µg PGF2a; Day 9, 200 µg GnRH + TAI 16 to 20 h later) and (2) control (n = 25; no treatment). Rates of ovulation for the first GnRH injection, detection of a corpus luteum (CL) at PGF2a injection, pregnancy and induction of cyclicity were greater (P < 0.05) with Ovsynch. There was no effect of body condition score (P ? 0.05). In conclusion, the Ovsynch protocol was not effective in obtaining acceptable pregnancy rate for TAI, but it was effective for induction of cyclicity in anoestrous and lactating Bos taurus × Bos indicus cows under tropical conditions.
