Nineteen (19) WAD goats aged between 6 and 8 months weighing between 4.16Kg and 5.90Kg were transported in a wagon for 3 hours 18 minutes. Collection of data on rectal temperature (RT) and heart rate (...

The present study was conceived with the aim of encouraging utilization of environmental wastes in the form of shed tree leaves for livestock feeds production. Three complete isonitrogenous (15.45 ± 0.17 % CP) diets, each constituted from shed leaves of Vitellaria paradoxa, Gmelina arborea or Daniella olliveri tree plus corn bran, soy bean meal, bo...

The escalating cost of commercial concentrate has worsened the irregular supply of high quality feeds for ruminants. Therefore feeding strategies to enhance the utilization of native pastures by ruminants is paramount. A 100-day study was conducted to investigate the effects of mixing palm kernel (PKC) cake with a formulated maize-based concentrate...

The experiment was carried out to determine the effect of urea-fortified all-concentrate corncob diets on hematological indices and serum biochemical parameters of West African dwarf goats. Fifteen (15) West African dwarf goats (divided into 5 groups – one control and 4 experimental) with average weight of 9.33kg were used for the study, which last...

A locally synthesized transition metal complex, cobalt-lumefantrine was assessed through laboratory and feeding trials to ascertain its usefulness as an agent for manipulation of the rumen in sheep grazing tropical pasture. The antimicrobial properties of the metal complex were examined on fresh rumen fluids at different concentrations (0, 0.010, 0...

A 28-day feed intake and digestibility trial was conducted with sixteen adult West African Dwarf goats to evaluate the influence of crude aqueous extracts of sheabutter leaf, added to maize-soy bean meal based concentrate diet (18.53 % CP). Goats were divided into four equal dietary groups balanced for body weight (range = 8.34 – 11.62; average = 9...

A 56-day feed intake, growth and digestibility trial was carried out to investigate the use of poultry manure as a fermentable nitrogen source in whole cassava plant-based concentrate fed to goats on basal Panicummaximum hay (9.18 % CP). Sixteen adult (2 years old; 12.48 – 16.72 kg initial body weights) West African Dwarf goats were blocked on the...

The effect of Omega-3-fatty-acid on performance was carried out in sixteen (16) West African Dwarf does between 12 to 18 months of age with an average weight of 10 kg. Supplementation of Omega-3-fattyacid was varied from 0 mg for control to 500, 1000 and 1500 mg for low, medium and high level (s), respectively. Blood samples were collected on days...

An experiment was conducted to investigate the utilization of Jatropha seed cake by Albino rats. Jatropha Seed Cake (JSC) treated by boiling, fermentation followed by extraction with equal volumes of hexane and ethanol was included in diets at graded levels of 5, 10, 15, 20 and 25%. Data obtained on performance and body organ indices showed that ra...

The effects of the fungus, Trichoderma harzanium , treated cassava waste on milk quantity and quality were investigated in a completely randomized design model with twelve lactating West African dwarf does. Goats were fed the experimental diets containing O (A), 20 (B), 30 (C) and 40% (D) Trichoderma treated cassava waste during a 13 week lactation...

A study was carried out to compare the rates of absorption of nickel from two nickel complexes and two nickel salts in the West African Dwarf (WAD) goat. Treatments consisted of oral administration of 5mg equivalents of elemental nickel from nickel sulphate hexahydrate (NiSO4.6H2O); nickel chloride hexahydrate (NiCl2.6H2O); nickel sodium monofluoro...

Fifteen weanling male West African Dwarf (WAD) goats (8-9 months old), of average initial live weight, 10.52 ± 0.87 kg were used to evaluate the effects of dietary cobalt supplements on feed intake, nitrogen retention and body weight gain while on low quality Panicum maximum hay (10.62 % CP) based diet. Three goat treatment groups offered oral supp...

Fifteen adult male West African Dwarf, WAD goats were used in an 84 -day dry matter and nutrient intake and digestibility, growth and nitrogen retention study to evaluate the leaf meals of Cassava, Leucaena and Gliricidia plants as protein supplements to low quality (7.63 % CP) Panicum maximum hay. The goats were divided into three groups balanced...
