  A study was carried out to determine the effects of varying levels of whole cottonseed on feed intake, weight gain and blood parameters in FriesianxBunaji and Bunaji heifers. Twenty FriesianxBunaji and 24 Bunaji pre-pubertal heifers were divided to 4 groups of 5 and 6 animals/group. Animals in each group were fed 1 of 4 experimental concentrate diets containing 0, 25, 50 and 75% whole cottonseed for 140 days. The result of the study showed that concentrate intake declined with increase in the level of whole cottonseed in dieting averaging 4.2, 3.3, 3.1 and 2.9 kg head -1day -1 in FriesianxBunaji fed 0, 25, 50 and 75% whole cottonseed diets, respectively. The corresponding intake figures for the Bunaji heifers were 3.1, 2.9, 2.5 and 2.2 kg head -1 day -1. Mean daily weight gain were 0.59, 0.59, 0.48 and 0.64 kg in FriesianxBunaji and 0.48, 0.41 and 0.50 C kg in Bunaji heifers fed 0, 25, 50 and 75% whole cottonseed levels, respectively. Changes in blood parameters were not significant in both FriesianxBunaji and Bunaji heifers across treatments. The study showed that heifers could be fed diets containing up to 75% whole cottonseed, respectively without adverse effects.

  Twenty Friesian x Bunaji crossbred and twenty-four Bunaji prepubertal heifers were fed 4 diets containing 0, 25, 50 and 75% whole cottonseed to determine effect of varying the level whole cottonseed on onset of puberty, response to oestrus synchronization with PGF and artificial insemination. The animals were fed the diets for 140 days. At the end of the feeding trials, oestrus synchronization was carried out on all the animals using PGF, injected intramuscularly in 2 doses of 2 mL each given 13 days apart. Compared to animals on the control diet (0% whole cottonseed diet), there was a slight delay in onset of puberty (age at first detection of palpable ovarian structures and first oestrus) with inclusion of whole cottonseed in the diet. Following oestrus synchronization with PGF, interval from treatment to onset of oestrus increased. Compared to the animals on the control diet, oestrus response rates, oestrus activities (vis-à-vis number of mounts) and heat duration declined significantly (p<0.05) in both Friesian x Bunaji and Bunaji heifers with increasing level of whole cottonseed in the diet. Level of whole cottonseed had no effect on conception rates of Friesian x Bunaji heifers. However, there was significant decline in pregnancy rates of animals fed 25, 50 and 75% whole cottonseed diet compared to the control (averaged pregnancy rates = 100, 80.3, 40.2 and 80.3% for the Friesian x Bunaji and 66.7, 50.0, 50.0 and 50% for the Bunaji on 0, 25, 50 and 75% levels of whole cottonseed, respectively).

  The study was conducted to determine the relative resistance of Red Sokoto and Sahelian goats to experimental infection with infective larva (L3) of Haemonchus contortus. At the age of about 7-9 months weaned goats were transferred to individual feeding pens and fed concentrate at 08:00 h and given Digitaria smutsii hay ad libitum. Fifteen goats of each breed were divided into 3 groups of five animals each. Goats were either given 0 L3 kg-1 (treatment 1), 75 L3 kg-1 (treatment 2) or 100 L3 kg-1 (treatment 3), three times weekly for 3 weeks. The faecal egg count expressed in Eggs per Gram (EPG) was significantly higher (p < 0.05) for the Sahelian (1477±153.4) than the Red Sokoto (607±147.5). The PCV didn`t show any significant difference between breed however the difference between treatment was significant at p < 0.05. The average daily gain was higher for the Red Sokoto (11.2 g day-1) than the Sahelian (5.6 g day-1) even though the difference was not significant (p > 0.05). The mean total protein was statistically different between breeds. The Red Sokoto had higher (p < 0.05) than the Sahelian (64.6 ± 1.81 vs 57.6 ± 1.86). The mean albumin and globulin concentration did not differ significantly between breed. It was concluded that the Red Sokoto were relatively more resistant to Haemonchus contortus on the basis of faecal egg count, weight gains, changes in the PCV and total serum protein concentration.

  The milk production potentials and growth rates of Red Sokoto and Sahelian goats fed basal diets of maize stover and Digitaria smutsii (wolly finger grass) supplemented with concentrate was investigated in two separate trials. In experiment 1, ten multi-parous does were allocated to intensive management following kidding. Does were hand-milked twice weekly and the milk production recorded. Body weight changes of dam and kid, milk fat, milk solid were determined weekly over 12 weeks period. The average birth weight of the Sahelian (2.2 ± 0.23 kg) was significantly (p<0.05) higher than the Red Sokoto kids (1.0± 0.17). At weaning age, the average kid weight of the Sahelian (5.6 ± 0.42 kg) was significantly higher than the Red Sokoto (3.9 ± 0.44 kg). There was no significant difference (p>0.05) in daily milk yield and total lactation between the two breeds. The total solids and milk fat of 16.4 ± 0.39 and 3.7 ± 0.13% were significantly (p<0.05) higher for the Red Sokoto than the Sahelian (15.1 ± 0.39 and 3.2 ± 0.13%). The second trial was to evaluate the comparative growth of the Sahelian and Red Sokoto breeds of goats. Animals were group-fed based on sex and fed Digitaria smutsii hay supplemented with concentrate. The growth trial lasted for 150 days with a 14 day digestibility trial. The Average Daily Gain (ADG) were significantly (p<0.05) different for breed, as well as sex. The Red Sokoto (66.9 ±1.59) kids had higher ADG than the Sahelian (46.6 ±1.59). Similarly the males of the Red Sokoto (61.9 ±1.59) had higher ADG than the Sahelian males (46.7 ±0.59) and the females of both breed. The experiments demonstrated a linear increase in weight gains of Red Sokoto over the Sahelian and a slightly higher milk yield obtained from the Sahelian providing the basis to conclude that the Sahelian goat can adapted and fit into the production systems of Sudan Savannah rural farmers.
