A study was carried out to evaluate the effect of inclusion of yeast (Saccharomyces cerevisiae) on the performance, rumen characteristics and blood profile of West African dwarf (WAD) goats. Four (4) dietary treatments were prepared by adding 0 g, 0.5 g, 1.0 g and 1.5 g yeast to concentrate feed. Twelve (12) WAD goats with an average live weight of 10.17±0.53 kg were allocated to the four treatment lots in a completely randomised design and used in a feeding trial that lasted 70 days. Concentrate was fed at 3% of body weight while Panicum maximum as the basal diet was ad libitum. Data were collected on nutrient intake, rumen fermentation and microbial ecology, blood profile and then analysed using one-way analysis of variance. Results showed that inclusion of yeast did not affect (P>0.05) nutrient intake, rumen fermentation of WAD goats. Bacteria and fungi population were also not affected (P>0.05) by the inclusion of yeast, however there was an increase (P<0.05) in 9 9 pr otozoa from 0.73× 10 (control) to 1.33× 10 (1.0g yeast). Packed cell volume (PCV) of goats decreased (P<0.05) when goats were fed 1.5g yeast (20.93%) compared to control (24.37%). It can be concluded that addition of yeast to the diets of WAD goats did not affect their overall performance, increased population of rumen protozoa and reduced blood packed cell volume.

A study was conducted to evaluate nutrient intake and digestibility of Panicum maximum fed in combination with selected browse plants to West African dwarf (WAD) bucks. Four intact West African dwarf (WAD) bucks of mean body weight 17.50kg were used to conduct digestibility study in a 4 x 4 Latin Square design experiment. Four forage combinations, diets A, B, C and D were fed to the goats. Diet A, the control, was 100% Panicum maximuni, while diets B, C and D contained 60% Panicum maximum each plus 40% of Alchornea cordifolia, Manniophyton fulvum and Gmelina arborea, respectively. The study lasted 56 days in a 14 day x 4 change over periods. Data were collected on dry matter intake (DMI), nutrient intake and digestibility. Simple linear regression and correlation were used to assess the degree of relationship between some of the digestion components. The result of proximate analysis indicated that the diets (P. max + browse) B, C and D had significantly (p<0.05) higher dry matter (%DM) contents of 81.12, 81.09 and 80.68%, respectively, than the 75.71% for diet A (sole P.max). Crude protein content of 17.56, 15.62 and 17.52%, respectively were also higher (p<0.05) than the 8.38%for diet A. There was higher (p<0.05) ether extract content of 2.43, 2.38 and 2.32%, for diets B, C, and D, respectively than the 1.32% for diet A. The ash content of 10.71, 9.78 and 9.76% for diets B, C and D respectively, were also higher (p<0.05) than the 7.83% for diets A. Metabolizable energy (MJKg-1) values of 1.41, 1.42 and 1.42 for diets B, C and D were also higher (p<0.05) than the 1.31 for diet A. However, the crude fibre value of the diet A (27.26%) was significantly (p<0.05) higher than the 18.30, 19.30 and 18.58% for diets B, C and D. respectively. There were significant (p<0.05) differences in DMI among treatment means. Vitro significantly (p<0.05) higher for animals fed diets B(15.04). C(13.12 ) and D(14.48 ) wherein P.max was fed in combination with browse plants than in the diet A( 6.28) group fed sole Pmax. Faecal nitrogen showed no significant (p>0.05) difference among treatment means. Urinary nitrogen was significantly (p<0.05) higher in diet A group (0.39) than in diets B (0.30), C (0.34) and D (0.43) groups. There was positive nitrogen balance for all in the treatment groups. Apparent nitrogen digestibility (%) was significantly (p<0.05) higher in diets B (92.37). C (90.51) and D (97.63) groups than in diet A (79.49). Nitrogen intake (g/d) could not reliably predict faecal nitrogen (g/kgDM) in diets C and D groups. Absorbed nitrogen (g/d/WKg0.75) could not predict urinary nitrogen (g/d/WKg0.75) in any of the diets. Biological value (BV) of the diets were A (55), B (45), C (81) and D (97). The result of this study shows that the animals fed P. max + browse recorded higher DMI, nutrient intake and digestibility than the sole P.max diet. These evaluation indices were, however, mostly better in the diet B group (60% P.maximum + 40% Alchornea cordifolia). The combination of 60% P. maximum + 40% Alchornea cordifolia is therefore recommended for West African dwarf (WAD) goats reared in the humid tropics of Nigeria for optimum intake and improved nutrient utilization.

In the tropics, supplementing concentrates with grasses, especially during the dry season could improve protein to energy ratio in ruminants thereby improving optimum production. Also, supplementation with a protein source enhances the production capacity of ruminants. Therefore, this study was designed to determine the nutrient digestibility and rumen fermentation kinetics of Panicum maximum supplemented with brewers dried grains and dried cassava peels based diets by West African Dwarf (WAD) lambs. Nine lambs of about 9 months in age and bodyweight ranging from 10.5kg-16.5kg were randomly divided into 3 groups and assigned to the following diets: Diet 1-100% Panicum maximum, Diet 2 - 81% DCP + 13.50% PKC + 2% Oyster shell + 2% Salt + 1.50% Premix and Diet 3 - 81% BDG + 13.50% PKC + 2% Oyster shell + 2% Salt and 1.50 Premix. Result showed that animals on diet 1recorded the least significant (p< 0.05) dry matter digestibility (55.00%) to those on diets 2 and diet 3. Animals on diet 3 recorded the best crude protein digestibility (66.88%) which was significantly different (p<0.05) from those on diets 1 and 2 (53.04% and 56.79%). Animals on diet 1 recorded the highest significant (p<.0.05) amount of ammonia nitrogen at O and 4hours post feeding. The same trend seems to occur for volatile fatty acids (acetate, propionate and butyrate) at O hour post feeding. However, at 4 hour post feeding, animals on diet 3 recorded a slight numerical advantage over other animals. It can therefore be deduced from this study that diet 3 was most preferred as evident from the chemical composition of the feed and nutrient digestibility of the lambs.Keywords: Dried cassava peels, brewer’s dried grains, digestibility, fermentation kinetics and lambs.

A twelve-week trial was conducted to determine the nutrients intake, digestibility and nitrogen utilization of West African dwarf (WAD) goats fed diets containing graded levels of alkaline treated malted sorghum sprout (AMSP) using Panicum maximum as the basal diet. A total number of sixteen (16) WAD goats with an average live weight; 5.8 ± 0.6 kg were allotted on weight equalization into four (4) dietary treatments consisting of four goats per treatments in a completely randomized design. Four (4) diets were formulated to contain 0, 20, 40 and 60% AMSP. Data was collected on nutrients intake, digestibility and Nitrogen utilization parameters. Significant difference (P<0.05) were observed in all the nutrient intake parameters observed except for dry matter intake. Goats fed 40% AMSP recorded the highest total ash intake (27.01%), total acid detergent fibre (11.46%) and total cellulose intake (83.13%) compared with other dietary treatments. There was no significant difference (P>0.05) in all the nutrient digestibility parameters except the ether extract, ash, cellulose and hemicellulose. The highest Ash (66.16%), cellulose (82.47%) and hemicellulose (82.26%) contents were obtained in goats fed 40% AMSP. There were no significant differences (p>0.05) among the Nitrogen metabolism variables observed except total nitrogen intake and nitrogen balance. Goats fed 40% AMSP based diet recorded the highest Nitrogen retention (62.18%). It can therefore be concluded that 40% AMSP can be used as potential sources of supplements in ruminants feed most especially during dry season as it enhanced nutrient intake, digestibility and nitrogen balance.

The study was conducted to determine nutrient intake and digestibility of West African dwarf goats fed graded levels of Afzelia africana and New bouldia laevisas supplements to Panicum maximum. Twenty female West African dwarf goats aged between 5 and 7 months old with mean live weight of 6.62±0.41kg were allotted to five dietary treatments with two replicates of two goats per treatment in a completely randomised design. The compared diets were: T (100% Panicum maximum), T (25%Afzelia africana and 75% Panicum maximum), T (50% Afzelia africana and 50% Panicum maximum), T (25% New bouldia laevis and 75% Panicum maximum) and T (50% Newbouldia laevis and 50% Panicum maximum). A metabolism trial was conducted at the end of the feeding trial to assess the diets on nutrient digestibility after the nutrient intake study of the goats. Results obtained showed that total hemicelluloses intake (62.48g.day ) was significantly (p<0.05) higher in T compared with other diets. Total crude protein intake(43.45g.d) and hemicelluloses digestibility(92.20%)were higher significantly (p<0.001) and (p<0.01) respectively in T . Total lignin intake (36.22g.d )and organic matter digestibility (77.70%) were significantly better (p<0.05) and (p<0.01) respectively in T . Digestibility of neutral and acid detergent fibre (55.71% and 49.79%) were significantly higher (p<0.05) and (p<0.001) while dry matter digestibility (83.49%) was significantly better (p<0.01) in T than other treatment diets. Total dry matter, organic matter, neutral detergent fibre, acid detergent fibre and cellulose intakes with digestibility of crude protein, lignin and cellulose were not significantly (p>0.05) affected by treatment diets. It was concluded that the combination of Panicum maximum based diet with Newbouldia laevis in a ratio of 50:50 had the potential to enhance nutrient digestibility in goats.

An experiment was conducted for 37 days for the purpose of investigating Rumen Fermentation Characteristics of West African Dwarf Sheep Fed supplementary diets containing Water-Washed Neem (Azadirachtaindica a. Juss0 Fruit and garlic (Alliumsativum). The experimental design used was a completely randomized design and the obtained data were subjected to analysis of variance (ANOVA). 12 West African dwarf Sheep were randomly allotted into 4 treatments of 3 replicates per treatment, these treatments were supplements containing 0%, 5%, 10% neem and 1.25% garlic. Panicum maximum was fed as the basal diet. The basal and supplementary diets were fed at ratio 50:50 and at 3% body weight on dry matter bases. At the end of 37 days feeding trial, rumen liquor from the experimental animals were collected for rumen fermentation characteristics and in vitro gas production. The pH of the rumen liquor had values ranging from 6.30 - 7.00 and there was a significant difference between the 4 treatments. Treatment IV had the highest acetic acid and butyric acid production while treatment II had the lowest. However, there was no significant difference amongst the 4 treatments. Propionic acid was highest for treatment I while treatment II had the lowest value. For the propionic acid, the treatment that had no inclusion of neem and garlic (the control treatment) had the highest mean value for the study. The in vitro production obtained for a standard feed sample incubated in the rumen liquor obtained from the 4 treatments were significantly affected by the inclusion of neem and garlic. It is then concluded that the inclusion of neem at 10% and garlic at 1.25% in the supplementary feed of WAD sheep will significantly reduce methane production and support ruminant production.

Absorbed 0.75 0.75 nitrogen (g/d/WKg 0.75 ) could not predict urinary nitrogen (g/d/WKg 0.75 ) in any of the diets. Biological value (BV) of the diets were A (55), B (45), C (81) and D (97). The result of this study shows that the animals fed P. max + browse recorded higher DMI, nutrient intake and digestibility than the sole P.max diet. These evaluation indices were, however, mostly better in the diet B group (60% P. maximum + 40% Alchornea cordifolia). The combination of 60% P. maximum + 40% Alchornea cordifolia is therefore recommended for West African dwarf (WAD) goats reared in the humid tropics of Nigeria for optimum intake and improved nutrient utilization.

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.
