TWENTY-FOUR rams of the West African Dwarf X Yankasa crosses, 6 to 7 months old, ranging in liveweight from 11 to 14 kg were randomly alloted to maize, sweet potato and cassava based rations. These rations constituted the concentrates which were fed as supplement to Cynodon nlemfuensis. Three rams from each treatment were slaughtered at the end of 30 day and another set of three rams each were slaughtered on the dietary treatments and other nine, 140 day later Replacement of the conventional maize grains by dried milled cassava and potato tubers in sheep diet did not dentess the growth rate, dressing-out percentages, major cuts, quality of the organs. and the general performances of the animals. Sweet potato based diet however improved the feed per gain estimate, the fats and protein content of the carcass. The highest proportion of lean ment was produced by the animals fed cassava based diet.

The study evaluated the effects of level of feed offer on dry matter intake (DMI) , digestibility, the parts of plants selected and on the growth rate of West African dwarf (WAD) goats without resulting in toxicity. Seven different levels of feed offer ranging from 40g/kg0.75/day to 130Wkg0.75/day in increments of 15g/kg0.75) were fed to two groups of goats. The first group was fed 100% Gliricidia while the while the second was fed 50% Gliricidia and 50% Leucaena diet (50/50). The level of feed offer had significant effect on the DIM and digestible DMI (DDMI) of the goat (P < 0.01). The Leucaena intake in a 50/50 diet was always higher than the Gliricidia intake except at 55g1kg0.75 offer level. The level of feed offer had significant effects on the parts of plants selected (P < 0.01.) and on the growth rate. The leaf intake was statistically higher than the stem intake (P < 0.01). All the goats on 40g/kg0.75 and 55g/kg0.75 on a 100% Gliricidia diet lost weight while only those on 40g/kg0.75 lost weight on a 50/50 diet. There was no significant difference in the growth rate of goats on feed offer levels of 70g to 130g/kg0.75 (P > 0.05). The study indicate that goats performance was higher on a mixed browse diet than on Gliricidia alone. Goats performed best at 100g/kg0.75 offer level.

Malted sorghum sprout (MSP) is an agro-industrial by-products rich in organic nitrogen and amino acids which can be used to enhance ruminant nutrition. A study was conducted to assess the nutritive value of MSP as supplementary on the performance characteristics and blood profile of West African dwarf (WAD) goats. MSP was collected, air-dried and then incorporated at different inclusion levels of 0, 10, 20 and 30% to formulate four dietary treatments T , T , T and T , respectively, with T - T being supplemented with Roxazyme G2 1 2 3 4 2 4 enzyme at 0.5g/kg. Twelve WAD bucks with an average weight of 7±0.5kg were assigned into four dietary treatments with three bucks per treatment in a completely randomized design over a period of 84 days. Data were obtained on performance characteristics, haematological and serum biochemical indices. Performance characteristics showed that average concentrate consumed (229.04g/day) and average daily weight gain (44.44 g/day) of WAD goats were significantly (P?0.05) higher in goats fed 20% MSP with enzyme supplementation. Dietary MSP with enzyme supplementation significantly (P?0.05) influenced the total protein (TP), aspartate amino transferase (AST), alanine amino transferase (ALT), white blood cells (WBC) and red blood cells (RBC) across the treatments. 3 3 TP (7.05g/dL) and WBC (7.88 x 10 /mm ) were significantly (P?0.05) higher in goats fed 20% MSP while globulin values increased significantly (P?0.05) across the dietary treatments (3.94 – 5.05g/dL) and is within the normal levels expected of healthy goats. It is concluded that dietary MSP with enzyme supplementation at 20% improved the performance, hematological and serum biochemical indicess of WAD goats without any adverse effects.

Dwarf Sheep

ABSTRACTA study was made of some aspects of reproduction in the Nungua Black Head and the Ghanian variety of the West African Dwarf sheep. The gestation period of the two breeds was similar: 150 and 148 days respectively. Ewes mated in August and September tended to have slightly longer gestation periods than those mated in March. The mean birth weights were 2·2 kg in the Nungua Black Head and 13 kg in the West African Dwarf. Type of birth affected the weight of lambs at birth. The Nungua Black Head had no triplets, 0·132 twins and 0·868 singles. The West African Dwarf was more prolific: 0·402 singles, 0·557 twins and 0·041 triplets. The weight advantage of the Nungua Black Head lambs at birth was maintained to weaning and they also had better survival rates. The adjusted 12-week weaning weights averaged 9·8 and 5·8 kg respectively for the Nungua Black Head and West African Dwarf. What the West African Dwarf lost in individual weight it appeared to make up in numbers so that, when the breeds were compared in terms of kg of lamb weaned per ewe mated, there was no significant difference between them.

SUMMARYThe effects of infection with T. vivax in mid- or late pregnancy on food intake and utilization, liveweight changes, abortion rate and lamb growth rate were investigated in West African Dwarf ewes at lbadan, Nigeria in 1990. Rate of liveweight gain by ewes infected during mid-pregnancy (IMH) was16 g/day compared with 33 and 37 g/day for the uninfected ewes offered medium (CM) or high (CH) plane diets. Although digestibility coefficients were not affected, intake of digestible organic matter was higher in CH ewes than in IMH and CM ewes. Nitrogen retention at mid-pregnancy on a metabolic size basis was higher in CH ewes than in CM and IMH ewes.Lamb birth weight and survival rate were lower in infected ewes. Ewes infected in mid-pregnancy (IMH) and in late pregnancy (ILH) had mean birth weights of 1·4 and 1·0 kg compared with CM and CH ewes, which had mean birth weights of 1·9 and 2·0 kg respectively. Observed survival rates were 63, 15, 75 and 80% for lambs nursed by IMH, ILH, CM and CH ewes respectively. During the first 6 weeks postpartum, lamb growth rate in all groups did not differ. However, during weeks 7–12 postpartum, lambs nursed by IMH ewes had significantly lower growth rates. Weaning weight was also lower in lambs from IMH (5·0 kg) dams than in lambs from CM and CH dams (7·1 kg). Infection during late pregnancy was more severe and all infected ewes lost weight due to reduced feed intake and fever. T. vivax infection in sheep is responsible for reproductive wastage, abortion, poor lamb growth and ewe mortality.

Southern Border

Total sheep population in Nigeria is probably around 8 million (anonymous, 1975). The majority of these sheep live in the northern part of the country. The three most important breeds in the north are the Uda, the Balami and the Yankasa. The former two are examples of the typical longlegged, long-tailed, hairy sheep, living along the southern border of the Sahara. The Yankasa occupies the middle and most of the northern part of the country. It probably developed as a cross between the West African Dwarf (or Forest) Sheep from the south and the Uda from the north. It possesses the heavy neck ruff that is typical of the West African Dwarf but is taller and heavier.
