  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.
