SUMMARYBreeding records over 12 years (1977–89), involving 455 West African Dwarf does derived from an original population of 133 breeding does, were used to examine the influence of dam age on the incidence of multiple births and perinatal reproductive wastage due to abortion and neonatal deaths. The animals were semi-intensively managed in two goat research units at the University of Ibadan Teaching and Research Farm.The regression results showed that the variable component, multiple births, increased (P < 0·01) linearly with advancing age of the doe, while the incidence of abortionsand neonatal deaths increased (P < 0·01) exponentially with doe age. Graphs plotted from the regression results indicated a sharp increase in the incidence of abortion and neonatal deaths between the ages of 6 and 7 years. This suggests that the practice of keeping these animals for longer than necessary, especially in rural areas of the country where they are mostly reared and kept for prestigious reasons, should be re-evaluated. Therefore it is recommended that to maintain an economically viable production system, does should be culled between the ages of 6 and 7 years and the provision of replacements planned accordingly.

Six Red Sokoto (RS) and six West African Dwarf goats (WAD) aged 12 months and housed individually were reared for five months at the Small Ruminants Improvement and Multiplication Research Unit of ESUT, Abakaliki Campus. The animals were allowed to graze in the University Paddocks containing both native and introduced pastures, browse plants and leguminous herbage. The grazing period lasted from 0800 - 1200 hours in the morning and 1500 - 1700 in afternoon daily and between these two periods they were fed supplemental diets. The results showed that there were highly significant difference amongst the members of the genotypes whose mean body weights were ranged from 24.71 $ 0.083 - 40.750 0.55 (RS) and from 14,98+ 0.47 - 27.52 0.73kg (WAD). The heights at the withers and body length measurements also showed a highly significant increase (P< 0.01) in the genotype during the period. The two genotypes differed remarkably (P< 0.01) from each other with RS being superior in body weight and height at the withers, and body length. However, the measurements taken of the thigh size and hearth girth circumference revealed no real difference between the RS and WAD (P >0.05). The findings indicate anthropometric areas requiring genetic improvement among the WAD, and at the same time serve as a pointer to the amount of response shown by the Maradi goats to management in the wet humid tropical environment to which it was being exposed.

A summary is given of work on flocks of West African Dwarf goats at Wageningen, the University of Ife (Nigeria) and a village in Nigeria. It was concluded that these goats are suitable for meat production under low and high levels of feeding and management. Under intensive management, daily gain averaged 80 g (0.3-0.4% of mature body weight), and the number of weaned kids produced per [female] per yr 2.56. Goats fed only roughage gained 43 g per day.

An outbreak of acute coccidiosis is reported in West African Dwarf (WAD) goats kept under a semi intensive management system at the University of Ibadan farm. During the period of the outbreak, clinical signs observed among the animal included anorexia, fever, coughing, ocular and nasal discharges and diarrhoea. Sixty nine out of eighty-five (85%) animals were scouring, 6 out of 20 (30%) pregnant did abort, 8 out of 80 (10%) died through severe infection. Average oocyst counts was 2.73 x 10°/gram faeces in kids and 0.9 x 10 gram faeces in adult goats. Eimeria species predominant in goats and percentage occurrence were E. arloingi (77.5%), E. ninakohlyakimovae (62.89%), E. hirci (58.6%). E, alijevi (39.5%). Areas of glandular degeneration and necrosis of epithelium of the small intestine were seen. Also coccidia schizonts, immature oocysts, and neutrophilic infiltrations can be seen in the intestinal mucosa. The presence of pathogenic species of the Eimeria in WAD goats suggest that coccidiosis may be contributing to the enteric syndromes, poor feed conversion and low productivity

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.

Abstract This study investigated the effects of feeding ensiled graded combinations of cocoa pod, cassava pulp and Acacia leaf on haematological and serum biochemical of West African Dwarf goats. In the bid to control environmental pollution, the wastes of cocoa and cassava were applied as alternative feed ingredients for the goat in spite of its low nutrients’ quality and digestibility. A total of Twenty-eight (28) WAD goats (bucks), aged 4 to 5 months with average body weight of 7.00±0.2kg was used in a completely randomized design for a 45 days study to evaluate the blood profiles of goats fed diet combinations (0:60:40) to (60:0:40). The results revealed significant differences in some of the blood parameters measured among the treatments. The red blood cell, packed cell volume and haemoglobin ranged from 4.90-7.87x106/ul, 19.25-26.83% and 7.33-11.15g/L respectively. The concentrations of mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration varied significantly (p < 0.05), white blood cell (5.57-9.75x109L) were comparable and lymphocytes (%) ranged from 43.85-55.67. For serum biochemistry, values obtained for total protein and albumin with sodium followed the same trend while cholesterol, urea, creatinine and glucose followed the same trend. Alanine amino transferase, Aspartate aminotransferase and Alkaline phosphatase varied significantly (p<0.05) among the treatment groups. Since the parameters measured were within the normal range for goats’ blood profile, combinations of cocoa pod, cassava pulp with acacia leaves in the ratio of 0:60:40 to 20:40:40 as browse plants do not have any deleterious effect on the health of the animals.

Vetiver is a perennial grass of tropical origin, commonly used as edge row plants for the control of erosion. Being leafy and with a high tillering ability, it has not been properly integrated as forage for ruminants. Thus, an experiment was carried out to determine the effect of ensiling a four week re-growth of vetiver grass with cassava peels on rumen and blood metabolites of West African dwarf goats. Sixteen goats were used for the study. A completely randomized design was used with four animals per treatment. Vetiver grass was ensiled with cassava peels at ratio (A) 80:20, (B) 70:30, (C) 60:40 and (D) 50:50 were provided ad-libtum at 5% body weight. Rumen and blood samples were collected at the end of the experiment which lasted for 90 days. Results of the study showed rumen ammonia nitrogen (NH3-N) concentration of 7.25-7.93mg/100mL, and pH of 6.75-6.81. Variations among the treatments were within the acceptable range for rumen microbial activity. There was a uniformly low plasma urea (4.36-5.16mm/l). Glucose (85.36-89.04g/dL), total protein (6.42- 7.50g/dL), cholesterol (60.95-66.19g/dL), haemoglobin (10.9-12.7g/100ml), packed cell volume (30.0-31.0%) and white blood cell (10.25-10.67×103/ul) were within the range reported for healthy goats. Ensiled vetiver grass with cassava peels had no detrimental effects on the rumen and blood parameters of the experimental animals.
