  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.

  The efficiency of EAZI-Breed™ CIDR® and FGA-30® intravaginal sponges in synchronizing estrus was investigated in prepartum Yankasa Ewes. About 20 randomly cycling pre-partum Yankasa ewes aged between 1.5-2 years and weighing between 13-15 kg was used for this study. They were randomly assigned into two groups, Group A (FGA, n = 10) and Group B (CIDR®, n = 10) for 14 days. Natural mating by a fertile ram was performed following progestagen withdrawal for ewes detected to be on heat. Estrus response in Group A and B was 70 and 80%, respectively. The time to estrus onset following progestagen withdrawal for FGA-30 and CIDR (Mean±SEM) was 43.60±6.98 and 23.57±4.07 h, respectively. In Groups A and B, the duration of induced estrus was (46.65±3.08 and 53.90±5.87 h) while estrus cessation was (90.37±8.44 and 77.92±4.24 h) post withdrawal of the devices. The interval from withdrawal of progestagen to onset of estrus was (p<0.05) longer in FGA than in CIDR (43.60±6.98 vs. 23.57±4.07 h). However, the duration of induced estrus period was shorter in the FGA group than the CIDR group. Retention rate was lower in group A (60%) than B (90%). Drawstring breakage observed in FGA sponges was absent in CIDR devices (20% versus 0) while vaginal discharge rate was higher in group A. These results show that although FGA and CIDR devices are equally efficient in synchronizing estrus in prepartum Yankasa ewes, CIDR provides higher estrus response rate, shorter time to estrus, longer duration of estrus, higher retention rate and ease of application. Consequently, the use of CIDR is recommended.

  The efficiency of EAZI-Breed™ CIDR® and FGA-30® intravaginal sponges in synchronizing estrus was investigated in prepartum Red Sokoto does. About 19 randomly cycling pre-partum Red Sokoto does aged between 1.5-2 years and weighing between 12-14 kg were used for this study. They were randomly assigned into two groups, Group A (FGA, n = 10) and Group B (CIDR®, n = 9) for 21 days. Natural mating was performed following progestagen withdrawal for animals detected to be on heat. Estrus response was 20 and 55.6% in groups A and B, respectively. The time to estrus onset following progestagen withdrawal for FGA and CIDR (Mean±S.D.) was 93.09±2.06 and 50.29±4.71 h; duration of induced estrus (0.08±0.05 and 39.99±6.05 h) while estrus cessation was (93.14±2.03 and 90.48±4.69 h) in group A and B, respectively. Interval between withdrawal of progestagen and onset of estrus was significantly (p<0.05) longer in FGA compared to CIDR. The duration of induced estrus period was significantly (p<0.05) longer in CIDR treatment. Retention rate was 100% (FGA) and 88.9% (CIDR) in group A and B, respectively. Drawstring breakage was observed in FGA sponges but absent in CIDR devices. Also, vaginal discharge rate was higher in FGA than CIDR groups. These results show that CIDR devices are more efficient in synchronizing estrus in prepartum Red Sokoto does. This is because CIDR provides higher estrus response rate, shorter time to estrus, longer duration of estrus, absence of drawstring breakage and better ease of application. Therefore, the use of CIDR is advocated.
