  Body weight and body linear measurement (Diagonal body length, Height-at-withers, sac pelvic width, Heart girth) of 259 West African Dwarf (WAD) goats (both sexes) in three age groups (Kid, yearling and Adult) were measured. The least square means for body weight were 6.40, 10.5 and 18.9 kg for kid, yearling and Adult respectively. Means of other body linear measurements also vary within each age group. The variables measured vary positively with age of the animals and the correlations of body weight with diagonal body length, Height at whither, sac-pelvic width and heart girth were high, positive and significant (p<0.01). There is sexual dimorphism in body weight and other body linear measurements in favour of the female goats. The correlation matrix of each of the variable or combination could be used in predicting live weight of the animals.

  The effects of dietary dry seed powder of G. kola (Bitter cola) at inclusion levels of (O, 10, 20, 30 and 40g per kg of feed), on heamatological parameters body weights and survival rate of pullets chicks were investigated in a study that lasted eight weeks. 250- day old pullet chicks were randomly allocated to five treatment groups. A treatment contained two replicates of 25 birds each. Results showed that G. Kola (Bitter Cola) dry seed powder inclusion in the diet improved weight gain in groups B, C, D and E.This compared favourable with that of the control group A. Weight gain for group E fed 40 g kg 1 feed dry seed powder of bitter cola was lowest when compared to other groups. Highest weight gain was however recorded for the group D birds (30 g kg 1 feed) dry seed power of bitter cola. For the period the experiment lasted, results in this study showed that the higher the level of inclusion of dry powered seed of Bitter Kola in the diet the lower the mortality rate recorded. This supports the antimicrobial activity of Garcinia Kola, as already documented in literatures. Heamatological (parameters such as Pack Cell Volume (PCV), Heamoglobin concentration (Hb), Red Blood Cells (RBC), Mean Corpuscular Heamoglobin MCH, Mean Corpuscular Volume (MCV), for test groups B, C, D and E were not significantly different from that of the control group A. However there was a significant (p<0.05) proliferation of the White Blood Cells (WBC), specifically the lymphocytes in this study. This probably explains the antimicrobial effect of Garcinia cola seeds, in views of the major role that the lymphocytes assume in the immune defense mechanism of the body, in both man and animals.

  The effect of different inclusion levels of bitter kola (Garcinia kola) dry seeds powder on feed intake, body weight gain/week, feed efficiency/ week and carcass characteristics of broiler chicks from day old to 4 weeks were studied. 200 broiler chicks of Anak strain were assigned to 5 groups in which each group contained 40 birds 0% (w/w), 2.5% (w/w), 5% (w/w), 7.5% (w/w) and 10% (w/w) dry seed powder of G. kola levels were included in the groups, respectively. Feed intake, body weight gain and feed efficiency were significantly (p<0.05) different. Feed efficiency is highest in 0, 2.5% and lowest in 5 and 7.5% inclusion levels. Absence of mortality was recorded which may be due to the autimicrobial effects of G. kola dry pounder seed inclusion in the diets.

  A feeding trial lasting 49 days was conducted using 16 weaner pigs of mixed breeds (Large White x Landrace) with initial average weights of between 8.13±0.80 kg and 8.25±0.85 kg to determine the effects of different levels of wild sunflower (Tithonia diversifolia Hemsl. A Gray) leaf meal on their growth, haematology and organ characteristics. The animals were randomly assigned to four dietary treatments using Complete Randomized Design (CRD). There were four individually penned animals per treatment. The Wild Sunflower Leaf Meal (WSLM) was included at 0, 10, 15 and 20% levels. Feed and water were offered ad-libitum. Records of growth performance, blood parameters and organ characteristics were taken. The values of average final weight, daily weight gain, daily feed intake and feed gain ratio were not significantly influenced (p>0.05) by the dietary treatments. Significant differences were not indicated (p>0.05) in haemoglobin, packed cell volume, red blood cells, mean corpuscular haemoglobin, mean corpuscular volume and mean corpuscular haemoglobin concentration. However, platelets, white blood cells, neutrophils and lymphocytes were significantly influenced (p<0.05). Kidney weight significantly increased (p<0.05) as levels of WSLM increased while heart, liver and spleen weights were not different significantly (p>0.05). It is evident that WSLM can be incorporated into the diet of weaner pigs at 200 g/kg

  Clinical observations and haematological changes following gastro-intestinal worm Haemonchus contortus was investigated experimentally in West African Dwarf (WAD) kids. 10 apparently healthy kids were experimentally infected orally with 750 infective larvae of Haemonchus contortus for a period of 5 weeks. The kids were weighed, the blood and faecal samples were collected before and after infection. Studentís t-test statistical analysis was used. The clinical observations on the infected WAD kids were normal rectal temperature, normal respiratory rate, normal heart rate and normal prepatent period with muscular weakness, anorexia, intestinal distension by worms, weight loss, reduced carcass quality, reduced feed intake, diarrhea and anaemia. The infestation was characterized by responsive normocytic-nomochromic anaemia. The weight and erythrocytic values were significantly different at p<0.05 and p<0.01 compared with the control. The erythrocytic indices, the total WBC and differential leucocyte counts were not significantly different at p>0.05 and p>0.01. The weight and erythrocytic values are directly proportional to the level of presence of helminthes eggs in the faeces.

  A site week feeding trial was conducted to study the effects of varying levels of castor fruit meal (CFM) on 40-week old Shavers 579 strains layers. Sixty-four layers were allotted to four dietary treatments, 1,23 and 4 which contained 0, 3.5, 7.0 and 14% castor fruit meal respectively. Layers in group (control diet) was significantly better (p<0.05) than the rest fed other diets in feed intake, hen-day production, egg weight, egg mass output and feed conversion efficiency. There were no significant differences (p>0.05) among the four dietary treatments in body weight, egg index, yolk percentage, albumen percentage, shell thickness and Haugh units. This study reveals that the inclusion of CFM in the diet of layers has adverse effects on their performance characteristics that are valued by poultry operators.

  207 WAD goats were randomly sampled in a survey study of some qualitative traits in Surulere local government of Oyo state, Nigeria. Traits studied were presence or absence of horns (Ho), Wattles (Wa), Beard (Bd); Coat colours and Hair types. Parameters studied revealed sexual dimorphism in the traits studied. Wattles, beard and horns were predominant in both sexes but more prominent in the male goats. The gene frequencies for the recessive alleles beard (0.67) and Horness (1.00) were higher than those of dominant alleles while dominant allele wattled gene (0.68) was more frequent. The majority of the goats sampled had black coat colour (36%) and smooth hair type (84%). The levels of variation in some of the traits surveyed indicated that the WAD goat has not been purified for such traits in the environment; rather their evolvement could be mainly for adaptive purposes.

  The effects of different inclusion levels of Garcinia kola on performance and egg quality parameters of layers were investigated for 8 weeks. A total of 40 Issa brown point-of-lay birds at 20 weeks of age were assigned randomly into 5 treatments, 1, 2, 3, 4, 5 with 8 birds/treatment and 4 birds/replicate. Birds on each treatment were fed different diets containing Garcinia kola at 0 g/1000 g, 10 g/1000 g, 20 g/1000 g, 40 g/1000 g and 80 g/1000 g/kg weight of feed. The control diets did not contain Gracinia kola. The trial lasted for 8 weeks. There were no significant differences (p>0.05) in egg weight, yolk weight, yolk index, yolk length, yolk colour, yolk albumen ratio, shell weight, shell thickness and Haugh unit of the eggs. There were significant differences (p<0.05) in performances, albumen weight and yolk height. This study showed that Garcinia kola did not pose any deleterious effects to the birds even at 80 g/1000 g/kg inclusion level but performance and egg quality were best at 10 g/1000 g/kg of dietary inclusion.

  The effect of dried seed powered of bitter (Garcinia kola) on weekly feed intake, body weight gain, feed efficiency and carcass characteristics of broiler chicks of Anak strain were studied. Broiler chicks were assigned to 5 treatment groups of 40 birds each per group Replicated twice with 20 birds per replicate. They were fed diets containing 0, 2.5, 5, 7.5 and 10 g/100 g dry seed powder of G. kola. There were significant treatment differences (p<0.05), in feed intake, body weight gain and feed efficiency. Feed efficiency was highest in 0, 2.5 g/100 g and lowest in 5 and 7.5 g/100 g inclusion levels. There was no mortality throughout the trial in any of the treatment groups.
