  A study was conducted with the field grown Pearl millet (Pennisetum americanum) and Lablab purpureus. The aim of the trial was to study the effect of the addition of Lablab legume in varying amount or the composition of daily intake and utilization of millet-silage by Yankasa sheep. Both crops were harvested separately, wilted, chopped and then mixed in four proportions (0:100, 15:85, 30:70 and 50:50% of lablab: millet, respectively) and ensiled. Silage treatments were found to be similar in concentrations of Dry Matter (DM), Organic Matter (OM) and Ether Extract (EE), while incorporation of lablab led to a small increase in Crude Protein (CP), Crude Fibre (CF) and Nitrogen Free Extract (NFE). All millet-lablab mixtures were adequately fermented with favourable aroma and colour. Comparisons of the four silage treatments revealed that, silage with 50:50 millet-lablab proportion was the most readily consumed by the rams with a mean intake of 48.4 g kg-1 W0.75 and lowest intake of 22.5 g kg-1 W0.75 for treatment with 0:100 lablab-millet proportion. Digestion coefficients declined steadily from the control (0:100% lablab-millet mixture) to 50% level legume incorporation. This investigation showed that the best performance of Yankasa rams on the basis of intake and digestibility was obtained from treatment with 50:50, lablab-millet mixtures.

  Adult African giant rats (Cricetomys gambianus, Waterhouse) were live-trapped in Zaria, Nigeria over a period of three years, cutting across all the seasons of each year. They were sexed and weighed immediately after capture, with the aim of determining changes in their live weights with seasons and sex. The overall live weight (Mean±SEM) of the African giant rats was 1.21±0.01 kg (n = 363). The live weight of African giant rats captured during the rainy season (1.17±0.02 kg) was significantly lower than that during the harmattan (1.25±0.02 kg; p<0.01) and hot-dry (1.23±0.02 kg, p<0.05) seasons. The male live weight of 1.28±0.01 kg was significantly higher (p<0.0001) than that of the female (1.14±0.01 kg). Male-biased sexual size dimorphism was observed during all the seasons, but was highest during the hot-dry season. The seasonal variation in live weight may be because food was more available in the wild during the harvest (dry) seasons (harmattan and hot-dry seasons) than the planting (rainy) season. The relatively low ambient temperature and relative humidity of the harmattan season was more favourable to growth, which may account for the higher live weight recorded during the season. The sex variation in live weight may be as a result of differential growth rate/time between the sexes. In conclusion, the African giant rats are lightest during the rainy season and the live weight of the male is higher than that of the female regardless of the season.

  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.
