Eighteen young West African dwarf (WAD) goats were used to compare the utilization of sewage sludge, poultry dropping and groundnut cake rations by WAD goats. Total dry matter intake of the animals fed diet A (groundnut cake based ration) and C (poultry dropping based ration) was significantly (P < 0.05) higher than dry matter intake of animal fed diet B (dry activated sewage sludge based ration). Total dry matter intake of animal fed diet A (664.6 g/day) appeared to be higher than those fed diet C (600.5g/day), although the differences observed were and significant. Values observed for apparent dry matter, ether extract and nitrogen-free extract digestibilities between animals fed the different diets were not significant (P > 0.05). crude fibre and crude protein digestibility values however varied appreciably. Values recorded (12.03, 1.04 and 10.42 g/day and 3.13, 0.28 and 2.72 g.day/w 0.75kg for animals fed diets A, B, and C respectively) for nitrogen balance and weight gains (56.8, -2.7 and 36.8 g/day for animals fed diets A, B and C respectively) were higher for animals fed diet A, followed by animals fed diets C and B respectively.

A study on effect of ensiled maize stover (EMS) and protein concentrate supplement (CS) on nutrient digestibility and nitrogen balance of ensiled maize stover (EMS) and concentrate supplement (CS) by West African Dwarf ewe was carried out. were showed Fifteen West African dwarf ewe with body weight of 14-16 kg allotted to individual metabolic cage in completely randomized design after preliminary feeding trial. The treatments were: A (75% EMS + 25% CS), B (50% EMS + 50% CS), C (25% EMS + 75% CS), D (100%EMS) and E (100% CS). The digestibility study lasted for seven days to determine dry matter digestibility, nutrients digestibility and nitrogen retention of WAD ewe fed ensiled maize stover and concentrate supplement. Results that dry matter intake (DMI), digestible crude protein (DCP), digestible crude fibre (DCF), digestible nitrogen free extract (DNFE), and total digestible nutrients (TDN) ranged from 321.65- 694.41gDM/day, 3.99 - 12.30%, 7.32 - 17.23%, 33.35 – 38.85% and 63.65 – 70.92%, respectively. Dry matter intake of ewe fed sole ensiled maize stover (diet D) was lowest (321.65gDM/day) while animals on diet C (25% EMS+75%CS) had the highest (694.41gDM/d). Apparent digestibility of CP was lowest (3.99%) in ewe fed sole EMS and highest (12.20%) in ewe fed diet C (25% EMS + 75% CS). Positive N-balance was observed for all the five diets, but it was highest (P< 0.05) in diet B (50%+50%) and lowest in diet D (100% EMS). Similarly, N-retention was highest (67.15%) in diet B and lowest (27.61%) in diet D. Therefore, diet made up of 50% ensiled maize stover and 50% concentrate is recommended for sheep production.

A 56 day trial was carried out to evaluate the response of West African Dwarf (WAD) bucks fed processed poultry dropping. Nine (9) West African Dwarf (WAD) bucks were assigned to three treatment groups in a completely randomized design (CRD) experiment with 3 bucks per treatment. The diets contained poultry dropping at 0% (T1), 10% sun dried poultry dropping (SDPD, T2) and 10% toasted poultry dropping (TPD, T3). The parameters evaluated included: dry matter intake (DMI), changes in body weight, feed conversion ratio (FCR), heart girth (HGC), body length (BLC) and height at withers, hematological and biochemical indices, and carcass characteristics of the bucks. Proximate analyses of the sun-dried poultry dropping, toasted poultry dropping, the treatment diets and the forages (Panicum maximum and Centrocema spp.) were also carried out. Concentrate dry matter intakes were 184.65g, 150.05g and 183.62g while forage dry matter intakes were 494.04g, 569.70g and 555.66g for T1, T2, and T3 respectively. Concentrate dry matter intake was similar (P>0.05) in T1 and T3 groups, but significantly (P<0.05) higher than the T2 group. The T2 group consumed significantly higher (P<0.05) forage than the T1 and T3 groups. HGC and HWC were 5.67cm, 2.33cm and 4.67cm, and 5.00cm 4.67cm and 4.00cm respectively. T1 and T3 had higher HGC than T2 group, while the T2 group recorded higher HWC than the T1 and T3 groups. The hemoglobin (Hb) values varied significantly (p<0.05) among the treatment means, and they were, 12.30, 11.30 and 12.00g/dl respectively. PCV (%) and WBC(x103/mm3 varied significantly (p<0.05) and the values were 37.00, 34.00 and 36.00 (%), and 39.00, 56.07 and 42.50(x103/mm3 respectively. Neutrophil and lymphocyte were also influenced significantly, the values were, 15.00, 10, and 31.00%, and 83.00, 86.00, and 66.00% respectively. Only serum urea was affected among the biochemical components, and the values were 0.87, 0.90 and 0.97 mg/dl respectively. Dressing percentage were 34.62%, 37.75% and 42.60% for T1, T2 and T3 respectively; the T2 and T3 groups were similar (P>0.05) but T3 was higher than T1. The values for shoulder were 10.67%, 10, 74% and 8.05%; the full gut values were 47.20% 38.56% and 28.68% for T1, T2 and T3 respectively. Liver, kidney and heart were 2.90%, 2.22% and 1.93%; 0.55, 0.47% and 0.42%, and 0.72%, 0.57% and 0.58% for T1,   T2   and T3 respectively. T1 showed significantly (P<0.05) higher relative weight values for liver and heart than the T3 group. Inclusion of processed poultry dropping up to 10% in the diets of WAD bucks did not affect their performance negatively. However simple sun drying is recommended based on the results of this study and it is also a cheaper and straight forward processing method for poultry dropping.

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.

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.

Abstract Recently, bioactive component of plant and plant parts have been used as rumen modifier to reduce methane gas production in ruminant livestock so as to reduce their contribution to the implicated greenhouse effect. This study therefore, evaluated the potential of Siam weed (Chromolaena odorata) leaves as a modifier of rumen fermentation in West African dwarf bucks. Fresh C. odorata leaves were harvested, air dried (3 weeks), milled using a 2mm sieve size and bagged for both proximate and phytochemical analysis. Concentrate diets were formulated with C. odorata leaf meal included in the diet at 0, 2, 4 and 6% of the whole diet. Rumen fluids were collected from West African dwarf (WAD) bucks (averaged 25kg) using suction tube and randomly allotted to the 4 experimental diets in a Completely Randomized Design. Incubation of inoculums was done for 96hrs with 12 replicates per treatment in a single run. Data obtained were analyzed using a One-way Analysis of Variance and means compared using Tukey’s Test. Results indicated that C. odorata had 969.0mg/kg dry matter, 175.1mg/kg crude protein, 204.3mg/kg crude fibre, 521.6mg/kg nitrogen free extract, 19.9 mg/kg saponin, 25.7 mg/kg tannin, 10.8mg/kg flavonoid and 12.6 mg/kg alkaloid. The addition of 2 and 4% C. odorata to the diets resulted in increased (P &lt; 0.05) in vitro gas production while C. odorata at 2 % reduced (P &lt; 0.05) the methane gas (%) estimate. In vitro organic and dry matter digestibilities, total digestible substrates and short chain fatty acids were increased (P &lt; 0.05) with C. odorata addition to the diets. This study concluded that the use of C. odorata as an additive at 2 and 4% inclusion increased total gas output; however, 2% inclusion will be beneficial as it reduced the methane output while maintaining higher gas production and digestibility.

Sixteen (16) West African dwarf goats weighing an average of 73 kg +1.2 were used in a completely randomized experimental design to determine the influence of feeding monensin on intake of some anti-nutritive components contained in the diet. Results showed that animals placed on monensin supplemented diets at levels of 15, 30 and 45 mg/kg DM had significantly (P<0.05) reduced intakes of tannin, oxalate, saponin and nitrate compared to those placed on the control diet (0 mg monensin/ kg DM). No significant difference (P>0.05) occurred amongst the monensin-supplemented groups. Fecal concentrations of tannin, oxalate, saponin and nitrate were similarly observed to reduced (P<0.05) with monensin inclusion. However, the percentage disappearance of each of the anti nutritive components was not altered (P>0.05). Reductions in total dry matter intake were observed in response to monensin supplementation at 15, 30 and 45 mg/kg DM relative to the control but dry matter digestibility and weight gain in animals were not altered. The reductions in the intake of dry matter with monensin feeding were assumed to have consequently caused the reductions in the intake of anti-nutritive components from the diet. This reduction caused by monensin would be of benefit, in a bid to lessen some of the nutritional problems usually encountered when animals consume large quantities of these components in the diet. Monensin inclusion at levels between 15 and 45mg/kg DM could therefore be recommended to alleviate toxicity problems commonly associated with intake of anti-nutritive substances in feed.

Twelve individually housed West African Dwarf (WAD) Bucks averaging 7.3 ±0.91kg were used to study the effect of varying levels of Bambara nut seed meal on the performance and carcass characteristics of West African Dwarf (WAD) Bucks. Four experimental diets designated A, B, C and D were formulated to contain 0, 10, 20 and 3096 Bambara nut meal (BNM) respectively. The twelve WAD bucks were divided into four (4) groups of three animals each. Each group was assigned to one of the four experimental diets in a completely randomized experiment. Each animal in a group represented a replicate. The experiment lasted 56 days, Data on Feed and dry matter intake, Weight gain, concentrate/gain ratio, dressing percentage and carcass quality was collected. Investigations revealed that incorporating BNM in concentrate diets did not significantly (P>0,05) enhance dry matter intake (405, 416, 395 and 407g/day for diets A, B, C and D respectively), daily weight gain (27, 60, 23, and 42g/day for diets A, B, C and D respectively) concentrate /gain ratio (9.36, 5.62, 10.60 and 8.37 for diets A, B, C and D respectively). Dressing percentage differed significantly (P<0.05) among treatment groups and was higher for goats fed the BNM- based diets compared to the control and the values were 40.56, 43.28, 41.85 and 41.34%for diets A, B, C and D respectively. Meat cut values showed that leg. loin and shoulder of all the Jointed parts (Shoulder, leg. loin, sets and ends) were significantly different (P<0.05) among treatment groups. The values were 13.20, 13.56, 12.12 and 11.44 %; 12.38, 11.30, 13.19, 11.97 %; 13.60, 12.37, 10.91 and 11.31 % for goats on diets A, B, C and D for leg, loin and shoulder respectively. There was significant differences (P<0.05) among treatment means for all parts that constitute the offal (head, skin, feet, full gut and empty gut) except for empty gut. On the average Diet B comparatively, yielded lower offal weight. It can be concluded that goats fed Diet B (10% BNM performed better comparatively in terms of feed conversion ratio, dressing percentage and bone to lean ratio.
