Efficient rumen fermentation is necessary for improved feed utilization and animal production. The use of feed additives to improve rumen fermentation is promising. Twenty-four West African Dwarf (WAD) bucks with an average weight of 10±2kg were randomly allocated on weight equalization to four treatment diets with 0, 2, 4 and 6% C. odorata inclusion for a period of three months. Six animals per treatment were used for the study with each animal served as a replicate. Weight changes were taken weekly and digestibility study was carried out. At the end of the study blood samples were also collected for haematological and serum assay. Results showed that the addition of C. odorata to the diets influenced (p<0.05) weight gain of experimental goats with goats on diets (4% inclusion) having the highest value (6.20kg). Nutrient intake, apparent digestibility of nutrients, and nitrogen utilization by WAD goats fed experimental diets were not (p>0.05) affected by dietary inclusion of C. odorata. Haematological parameters were not differed (p>0.05) across the dietary treatments. However, serum glucose and aspartate aminotransferase increased (p<0.05) with increase in inclusion of C. odorata. It can be concluded that the use of C. odorata as an additive at 4% inclusion increased weight gain of goats with normal blood ranges indicating no negative effect of goats' health.

A total of twenty (20) growing WAD bucks of about 7 - 9 months and having average weight of 9.64 kg were used in an 84 day trial to investigate the performance response of West African Dwarf (WAD) goats fed diets containing cowpea husk (CPH). Cowpea husk used for the study was collected from Nasarawa Eggon Local Government Area of Nasarawa State. Four experimental diets were formulated to replace maize offal with cowpea husk and designated A (0%), B (25%), C (50%), and D (75%) and used to feed the bucks. Results showed that none of the performance parameters showed treatment effect (P>0.05). The mean daily weight gain was 56.55 g/day, 52.75 g/day, 42.81 g/day and 50.49 g/day for diets A, B, C and D respectively. The mean daily feed intake ranged between 458.40 g/day -503.00 g/day, with treatments D and B having the highest and lowest numerical values, respectively. The apparent nutrient digestibility coefficient of dry matter (DM), crude fibre (CF), ash, nitrogen free extract (NFE) showed significant differences (P<0.05) among the treatments and some crude fibre fractions like neutral detergent fibre (NDF) and acid detergent lignin (ADL) were significantly different (P<0.05) among the treatments means. The concentrate feed cost/kg diet was between ₦63.85-₦73.74. The cost/kg weight gain was best for treatment B (₦617.05). The production efficiency was less than one for all the treatments. Cowpea (vigna unguiculata) husk can be used in the diets of West African dwarf goats without adverse effect on the performance indices and profitability

Four low cost feed samples were formulated using 0, 25, 50 and 75% levels of broiler litter processed into feed along with other feed ingredients. Sixteen (16) primiparous West African Dwarf (WAD) ewes aged between twelve and eighteen months old were dewormed using Ivermectin and dipped against ticks and fleas using diazintol. Oestrus was artificially synchronized in all the ewes using Iml of Prostaglandin - 2Fα administered intramuscularly, the animals were mated with rams of known fertility and lineage bred. Ewes were evaluated in a pregnancy trial while the lambs born were evaluated in a pre weaning growth trial. All the ewes were weighed before conception and bimonthly thereafter until parturition. The parameters studied were weight at mating, weight before and after parturition, weight changes during pregnancy, weight changes in lactation and nursing, lambs birth weights and daily weight of lambs, dam's weight at weaning and gestation length. Results obtained showed weight at mating, weight before mating, weight at parturition, gestation length, weight gain in pregnancy, weight change in lactation and nursing, lambs birth weights and daily weight gain of lambs were significantly affected (p<0.05) while dam's weight at weaning and lambs' weaning weight were not affected (p>0.05). Results of this study indicate that inclusion of broiler litter up to 50% in feed mixtures of ewes has no deleterious effect on the performance and health status of ewes during pregnancy and lactation.

Nutrient Utilisation

Crude protein is essentially needed for ruminants but expensive to supply. Mucuna puriens is a high yielding domesticated legume. When the legume is strategically combined with a fibre source, it will make a good diet for ruminants. Thus, a study was carried out to assess the effect of ensiling mucuna with maize forage on performance of rams. In the study, rams were fed silage combinations of Maize Forage (MF) and Mucuna pruriens foliage (MPF). Downy mildew and streak resistant (DMR-SR) yellow variety maize was planted and harvested as MF at six weeks of growth and ensiled with MPF at four levels : 1:0, 3:1, 1:1 and 1:3 for 21 days. All the four silages were fed to 20 WAD rams (12.00±0.25 Kg) in a completely randomised design for 105 days. Proximate composition of the silages, apparent nutrient digestibility of silages in WAD rams, feed intake and weight changes were determined using standard procedures, while feed conversion ratio was computed using standard procedures. Data obtained were analysed using descriptive statistics and ANOVA at α0.05...The dry matter (DM) was significantly higher in T1 (25.65±0.62) and T2 (23.48±0.47) than T3 (21.80±0.41) and T4 (21.57±0.40). The crude protein (CP) was highest in T4 (13.0±0.6) and least in T1 (8.0±0.2). The crude fibre was significantly higher in T1 (26.4±2.6) and T2 (26.2±2.0) than T3 (24.0±1.8) and T4 (21.6±0.9). Apparent digestibility of neutral detergent fibre (NDF) was highest in T2 (59.2±1.7) and least in T4 (37.7±1.9), while percentage nitrogen retention was significantly higher in T2 (43.2±3.8) and lower in T1 (20.0±4.3). The FCR for rams fed T2 was significantly lower (8.84±1.2) than T1 (9.76±0.80), T3 (9.60 ±0.60) and T4 (11.50±0.90) Ensiling maize forage with Mucuna pruriens foliage at 3:1 enhanced nutrient digestibility and growth performance in West African dwarf rams without any deleterious effect.

Malted sorghum sprout (MSP) is an agro-industrial by-products rich in organic nitrogen and amino acids which can be used to enhance ruminant nutrition. A study was conducted to assess the nutritive value of MSP as supplementary on the performance characteristics and blood profile of West African dwarf (WAD) goats. MSP was collected, air-dried and then incorporated at different inclusion levels of 0, 10, 20 and 30% to formulate four dietary treatments T , T , T and T , respectively, with T - T being supplemented with Roxazyme G2 1 2 3 4 2 4 enzyme at 0.5g/kg. Twelve WAD bucks with an average weight of 7±0.5kg were assigned into four dietary treatments with three bucks per treatment in a completely randomized design over a period of 84 days. Data were obtained on performance characteristics, haematological and serum biochemical indices. Performance characteristics showed that average concentrate consumed (229.04g/day) and average daily weight gain (44.44 g/day) of WAD goats were significantly (P?0.05) higher in goats fed 20% MSP with enzyme supplementation. Dietary MSP with enzyme supplementation significantly (P?0.05) influenced the total protein (TP), aspartate amino transferase (AST), alanine amino transferase (ALT), white blood cells (WBC) and red blood cells (RBC) across the treatments. 3 3 TP (7.05g/dL) and WBC (7.88 x 10 /mm ) were significantly (P?0.05) higher in goats fed 20% MSP while globulin values increased significantly (P?0.05) across the dietary treatments (3.94 – 5.05g/dL) and is within the normal levels expected of healthy goats. It is concluded that dietary MSP with enzyme supplementation at 20% improved the performance, hematological and serum biochemical indicess of WAD goats without any adverse effects.

In a 56-day feeding trial, an experiment was conducted to determine the effects of replacing maize with different levels of ensiled cassava root-leaf blends (ECRLB) on growth, carcass yield, blood profile and economics of production of weaner rabbits. Five experimental diets were formulated and fed to the animals; diet 1= a maize based diet (control diet), diet 2= 30% maize + 10% ECRLB, diet 3 = 20% maize + 20% ECRLB, diet 4= 10 % maize + 30% ECRLB, diet 5= 40% ECRLB. A total number of forty weaner rabbits with an initial average weight of 574.09g±20.03g were randomly allocated to the five dietary treatments in a completely randomized design (CRD) with eight animals per treatment. Data were collected on growth indices, economics of production, carcass characteristics and blood profile Increased (P<0.05) weight gain was observed as the percentage inclusion of ECRLB increased. Rabbits on diet 4 (10 % maize + 30% ECRLB) and 5 (40% ECRLB) recorded the highest (P<0.05) daily weight gain with a corresponding highest (P<0.5) final body weight. Similar FCR were recorded across the treatments Economics of production of animals on diets containing 30 and 40% ECRLB was the best (P<0.05). Carcass indices were not significantly (P>0.0) affected by the experimental diets. Rabbits fed ECRLB recorded lower (P<0.05) serum cholesterol and higher (P<0.05) serum glucose concentration compared to control. In conclusion dietary inclusion of ECRLB up to 40% improved performance and did not show any deleterious effects on all indices examined and is recommended.     Au cours d'un essai d'alimentation de 56 jours, une expérience a été menée pour déterminer les effets du remplacement du maïs par différents niveaux de mélanges racines-feuilles de manioc ensilées (le 'ECRLB) sur la croissance, le rendement de carcasses, le profil sanguin et l'économie de la production de lapins sevrés. Cinq régimes expérimentaux ont été formulés et nourris aux animaux ; régime 1= régime à base de maïs (régime de contrôle), régime 2= 30% maïs + 10% ECRLB, régime 3 = 20% maïs + 20% ECRLB, régime 4= 10% maïs + 30% ECRLB, régime 5= 40% ECRLB. Un nombre total de quarante lapins sevrés d'un poids moyen initial de 574,09 g±20,03 g ont été attribués au hasard aux cinq traitements diététiques dans une conception complètement randomisée (CRD) avec huit animaux par traitement. Des données ont été recueillies sur les indices de croissance, l'économie de la production, les caractéristiques de la carcasse et le profil sanguin. Le gain de poids accru (P<0,05) a été observé à mesure que l'inclusion en pourcentage de l'ECRLB augmentait. Les lapins de l'alimentation 4 (10 % de maïs + 30 % d'ECRLB) et 5 (40 % d'ECRLB) ont enregistré le gain de poids quotidien le plus élevé (P<0,05) avec un poids corporel final correspondant le plus élevé (P<0,5). Les 'FCR' similaires ont été enregistrés à travers les traitements Économie de la production d'animaux sur les régimes contenant 30 et 40% ECRLB a été le meilleur (P<0,05). Les Indices carcasse n'étaient pas significativement (P>0,0) affectés par les régimes expérimentaux. Les lapins nourris à l'ECRLB ont enregistré un taux de cholestérol sérique inférieur (P<0,05) et une concentration plus élevée de glucose sérique (P<0,05) par rapport au contrôle. En conclusion, l'inclusion alimentaire de l'ECRLB jusqu'à 40 % a amélioré les performances et n'a pas montré d'effets délétères sur tous les indices examinés et est recommandée.

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.

The present study was aimed to investigate the dietary effect of different levels of turmeric (Curcuma longa) powder on the performance of broiler during summer (June-July), 2013. Four experimental rations designated as T0, T1, T2 and T3 having 0%, 0.5%, 1.0% and 1.5% Turmeric (Curcuma longa) powder were fed to 120 broiler chicks (Ross 308), randomly distributed into 12 replicates, so as to have 3 replicates per treatment and 10 chicks per replicate. Average weight gain, feed consumption, feed efficiency, dressing yield and survivability were used as criteria of response to feeding turmeric powder. Organs weight including heart, liver and gizzard were also recorded. The mean body weight gain and average feed efficiency (feed gain-1) per broiler significantly increased (P<0.01) by turmeric supplemented feed compared to control feed. The average feed consumption and survivability of broiler chick non- significantly (P>0.05) improved due to by turmeric supplementation in the diets. Inclusion of turmeric powder caused slightly increased the carcass traits of broiler chicks i.e., average weight of liver, heart and gizzard but the differences were non-significant (P>0.05). A significant decrease (P<0.01) in abdominal fat pad and significant increase (P<0.05) in dressing yield was observed in chickens fed the turmeric supplemented diets. The results of the present study suggest that the use of turmeric (Curcuma longa) powder as feed additive at a level of 0.5% enhances the growth performances and carcass yield of broiler chicks.SAARC J.

The unresolved problem of quail is feed stress and high sensitivity of poultry of this species to feed quality. To eliminate such consequences it is possible with the use of various biologically active feed additives. However, their introduction into the diet automatically raises questions about the quality and safety of the products for the consumer. The purpose of the research is to conduct a veterinary and sanitary assessment of the quality of quail meat for feeding NDC. The purpose of the research is to conduct a veterinary and sanitary assessment of the quality of quail meat for feeding NDC. The object of study were the quails of the Pharaoh breed, at the age of 24 were divided into two groups: experimental and control 30 heads each. The birds were kept in cages with free access to food and water. Quails of the experimental group were added to drinking water feed additive "Nanocerium" at a dose of 8.6 mg per liter of drinking water. Nanocerium feed additive is an aqueous dispersion of NDC with average nanoparticle sizes of 2–7 nm. Antemortem examination of quails of both groups revealed a satisfactory clinical condition of birds. The average weight of the gut carcass of quails of the experimental group was higher by 8.3% compared to the control. Examination of 20 carcasses of quails showed that they can be classified as first class. According to organoleptic parameters, quail meat is of good quality in veterinary and sanitary terms. Microbiological studies of quail meat indicate no effect of NDC in the applied doses on its bacterial contamination. Chemical parameters of meat (pH, aminoammonia nitrogen, volatile fatty acids during storage in the refrigerator) (5 days, t = 4–5 ° C) tended to increase and were within the normal range for fresh product. Tissue in quails of both groups was not detected. The biological value of quail meat in both groups was identical and no toxicity. Tasting evaluation of the broth and meat showed that NDC did not affect the studied taste. The obtained results show that the quails that received the feed additive "Nanocerium" with water according to the indicators of veterinary and sanitary examination are of good quality, which allows to use it in human food without restrictions. Key words: poultry, nanocerium, organoleptic evaluation, microbial contamination, biological value, tasting evaluation.

The feed intake and reproductive performance of intensively managed West African dwarf (WAD) gravid does were investigated. Twelve does weighing 11.90-13.05kg were used for the study. The does were fed on pulverized maize-cob based diets; maize-cob/cassava peel (PMC/CSP), maize-cob/brewers' grain (PMC/BG), and maize-cob/cassava peel/brewers' grain (PMC/CsP/BG). The does were allotted to the three dietary treatments such that four individually housed animals, each serving as a replicate and were also fed with concentrate diet at 1% of their body weight. Oestrus was synchronized in the does using 1mL/10kg of Prostaglandin –Fα intramuscularly. Animals were mated with a proven buck. Dams were evaluated in a pregnancy trial while the kids born were evaluated in a pre-weaning growth trial. Dams were weighed at mating and fortnightly until kidding. Variables investigated were; feed intake, dam weight at mating, prior and after parturition, gestation length, weight gained during pregnancy, kid's birth and weaning weights, kid's daily weight gain, sex ratio. Feed intake revealed that does fed PMC/CsP recorded the highest total dry matter intake (TDMI) throughout the three trimesters (727.16, 832.85 and 637.08g/day) when compared to 339.38, 452.18 and 401.03g/day obtained for does fed PMC/BG. Weight gained was significantly (P<0.05) higher in does on PMC/CsP. Mean birth weight, weaning weight and daily weight gain were higher for kids whose dams were fed PMC/CSP/BG. It can therefore be concluded that diets used in this study may serve as alternative feed for gravid goats while goats fed PMC/CsP/BG had better reproductive performance.

Twenty-one early weaned West African dwarf (WAD) goats weighting 1 – 1.5kg at birth were used to asses the utilization of nutrients by kids fed soyabeans diet (SD) as replacer for milk. Replacement of milk with SD up to 50 percent had no significant (P > 0.05) effect on dry matter intake of kids. Nutrient digestibility values however decreased (P < 0.05) with replacement of milk with SD up to 50 percent level. The digestibility of nutrientts increased (P < 0.05)with age of the kids. Weight gain of the kids (up to 9 weeks of age) reduced with partial replacement of milk  with SD up to 50 percent level. Values recorded for average daily weight gain (g/day) for the kids for diets containing 0, 25, and 50 percent SD were 11.2, 6.7 and 3.0, respectively at 4 weeks of age and 24.3, 19.2 and 7.8, respectively at 6 weeks of age. 25 percent replacement of milk with SD gave adequate performance pre-weaned kids. The result also showed that that the level of replacement of milk with SD could be increased up to 50 percent only after 6 weeks of age.
