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

An experiment was carried out to investigate the performance and nutrient digestibility of West African dwarf growing rams fed mixture of Panicum maximum and Tridax procumbens supplemented with Cajanus cajan leaves for 56 days feeding trial. A total of twelve WAD rams were randomly allocated to three treatments with four animals per treatment while two animals served as replicate. The experimental diet was fed at 3% body weight of individual animals while Cajanus cajan leaves were supplemented at varied inclusion levels. The results revealed that animals fed T1 recorded the least weight gain (36.96g/day) while the highest weight gain (56.42g/day) was recorded for T3. The daily weight gain of animals was significantly different across all treatments (P<0.05). The highest DMI (18.30kg) was recorded on the T1, and the least value of DMI (17.40kg) was recorded in T3. The highest feed efficiency ratio (0.18) and the lowest value (0.11) were observed in animals fed T1 and T3 diet respectively. There were significant differences (P<0.05) in the nutrient digestibility parameters of the experimental animals. The results showed that T1 (100% sole Cajanus cajan leaves) promoted the best dry matter (DM) digestibility (89.56%) which was enough to meet the production and maintenance requirement of small ruminants while the lowest value (88.67%) of DMD was recorded in T2 . The highest crude protein (CP) digestibility (13.20%) was observed in T3 diet. The highest value for crude fibre digestibility (38.95%) and the lowest value (35.35%) were observed in animals fed T2 and T1 diet respectively. In conclusion, supplementation of Cajanus cajan leaves with mixture of Tridax procumbens and Panicum maximum as basal diet for feeding sheep enhanced nutrient intake, growth performance and improved nutrient digestibility without health challenges to the animals.

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.

A study was carried out to investigate the effect of feeding two varieties of cowpea haulm on  growth performance, nutrient digestibility and nitrogen balance in Red Sokoto bucks. The  experiment consisted of 15 Red Sokoto bucks of average weight of 10kg, which were balanced  for weight and randomly assigned to three dietary treatments with five bucks per treatment in  a complete randomize design. The three treatment diets consisted of Brachairia decumbens  hay as basal diet and concentrate diets which were supplemented with cowpea haulms at 0%  (Control), 10% (SAMPEA14) and 10% (SAMPEA15). The study lasted for 90 days. Total dry  matter intake (TDMI, g/day), total weight gain (TWG, kg), faecal (unit) and urine (unit)  outputs were recorded. Results indicated that the TDMI were different (P<0.05) with higher  intake (237.64 g/day) in bucks fed control diet, followed by 223.00 g/day 10% SAMPEA 15  and 10% haulm of Sampea 14 (206.49g/day) in the concentrate. The TWG and average daily  weight gain increased by 59.77% and 59.76%, respectively with respect to 10% SAMPEA 14  haulm inclusion compared to the control diet. The digestibilities of dry matter (DM), crude  protein (CP), crude fibre (CF), ether extract (EE) and nitrogen free extract (NFE) were  higher (P<0.05) in bucks fed diet constaining 10% SAMPEA 14 inclusion level compared to  the treatment diets. The quantity of N retained by the bucks was higher (P<0.05) with the  inclusion of 10% of SAMPEA 14 (3.79 g/day) compared to those fed 10% SAMPEA 15 (1.18  g/day) and the control diet (0.68 g/day). It is concluded that farmers should include 10%  SAMPEA 14 in concentrate diet of Red Sokoto bucks for optimum performance under smallholder production system.     Une étude a été menée pour étudier l'effet de l'alimentation de deux variétés des haulms de niébé sur la performance de croissance, la digestibilité des nutriments et l'équilibre azoté chez les mâles Red Sokoto. L'expérience s'est composée de 15 bucks rouges de Sokoto de poids moyen de 10kg, qui ont été équilibrés pour le poids et aléatoirement assignés à trois traitements diététiques avec cinq dollars par traitement dans une conception randomize complète. Les trois régimes de traitement se sont composés deBrachairiadecumbenshay comme régime basal et régimes concentrés qui ont été complétés avec des haulms de niébé à 0% (contrôle), 10% (SAMPEA 14) et 10% (SAMPEA 15). L'étude a duré 90 jours. La consommation totale de matière sèche (TDMI, g/day), le gain de poids total (TWG, kg), les sorties fécales (unitaires) et urinaires (unitaires) ont été enregistrées. Les résultats ont indiqué que le TDMI était différent (P<0.05) avec une consommation plus élevée (237.64 g/jour) dans le régime de contrôle alimenté par les mâles, suivi de 223.00 g/jour10% SAMPEA 15 et 10% de transport de Sampea 14 (206.49 g/jour) dans le concentré. Le TWG et le gain quotidien moyen de poids ont augmenté de 59.77 % et de 59.76 %, respectivement en ce qui concerne l'inclusion de 10 % de SAMPEA 14 haulms par rapport au régime de contrôle. Les digestibilités de la matière sèche (le 'DM'), des protéines brutes (le 'CP'), des fibres brutes (le 'CF'), de l'extrait d'éther (le 'EE') et de l'extrait sans azote (le 'NFE') étaient plus élevées (P<0,05) chez les mâles nourris à l'alimentation constaining 10% SAMPEA 14 niveau d'inclusion par rapport aux régimes de traitement. La quantité de N retenue par les mâles était plus élevée (P<0.05) avec l'inclusion de 10% de SAMPEA 14 (3.79 g/jour) par rapport à celles nourries 10% SAMPEA 15 (1.18 g/jour) et le régime de contrôle (0,68 g/jour). Il est conclu que les agriculteurs devraient inclure 10% SAMPEA 14 dans le régime concentré de bucksRed Sokoto pour une performance optimale dans le cadre du système de production des petits exploitants.

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.

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.

Wild cocoyam is a non edible plant found growing around riversides and can serve as source of energy to ruminants. Hence, a twelve weeks study was conducted to investigate the effect of wild cocoyam – urea meal on the growth performance and blood profile of West African dwarf (WAD) goats. Twelve WAD goats with an average weight of 7.25 ± 0.04kg were randomly allotted into four dietary treatments: T1 (raw wild cocoyam), T2 (urea treated wild cocoyam), T3 (urea treated cooked wild cocoyam) and T4 (urea treated fermented wild cocoyam), replicated thrice in a completely randomized design. Results obtained showed that the experimental diets significantly (p < 0.05) influenced the growth performance. Goats fed urea treated cooked wild cocoyam had the best feed conversion ratio (10.35), the highest values of dry matter intake (405.35 g/day) and daily weight gain (39.17 g/day) when compared to other dietary treatments. The dietary treatments did not significantly (p < 0.05) influence the haematological parameters except the red blood cells (9.62 - 11.67×106 mm3),white blood cells (4.07-9.05×106 mm3) and monocytes (1.00-2.50%). No significant (p>0.05) differences among the dietary treatments were observed in all the serum biochemical indices evaluated except for urea which ranged from 15.50 – 28.70mg/dl. It can therefore be concluded that addition of urea with processing, further improved the utilization of the experimental diets thus improving performance of the animals.

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 study was conducted to determine the effect of different nutrient densities on performance characteristics and faecal egg count of West African Dwarf (WAD) rams semi-intensively managed. Twenty four yearling lambs between 10-15kg were used for the experiment. The lambs were allotted to two treatment groups containing 12 animals per group. They were released into the paddock containing sown pasture to graze for 6 hours per day. The animals were randomly assigned to treatments containing two levels of protein-energy density: low energy, low protein (LELP) and high energy, high protein (HEHP) in a completely randomized design. Performance characteristics of WAD rams showed that protein and energy density have significant effect (P<0.05) on weight gain, daily weight gain and protein intake. Metabolic weight gain was influenced (P<0.05) positively by the protein and energy density. Animals fed HEHP diets had significantly (P<0.05) higher protein intake (54.66 g) than those fed LELP diets (22.92 g). The slope observed for animals on HEHP diet was lower compared to that of their counterpart on LELP diet. Hence, HEHP diets improved performance of West African Dwarf sheep as well as reducing the gastrointestinal parasite infection due to lower FEC recorded.

An experiment was conducted to evaluate efficacy of Lacto acidophilus on the growth performance, carcass characteristics and nutrient digestibility of broiler chickens. Two hundred and twenty five (225), one day old chicks were purchased from local commercial hatchery and were randomly divided into 5 groups and each group had 3 replicates of 17 chicks in a completely randomized design. Five iso-caloric and iso-nitrogenous (ME 2998kcal/ kg and CP 23.21%) broiler starter and finisher (ME 2990 kcal/ kg and CP 20.33%) experimental diets containing 0, 150, 200 and 250g Lacto acidophilus® for T1-T4 respectively and T5 containing Oxytetracycline were formulated. Broiler starter and finisher diets were fed from 0-3 and 4-7 weeks, respectively. Data obtained were subjected to analysis of variance using Statistical Analysis System and significant differences between treatments means were separated using Duncan Multiple Range Test. There were significant (P<0.05) difference in final weight, weight gain, average daily weight gain (ADWG), total feed intake (TFI), average daily feed intake (ADFI), feed conversion ratio (FCR) and feed cost/kg gain across the treatment groups. It was observed that chickens fed dietary Oxytet (oxytetracycline) had the best results in terms of the final body weight, weight gain and ADWG but similar to those fed 150 and 200g Lacto acidophilus® addition levels. The percentage dry matter (DM), crude protein (CP), crude fibre (CF), ether extracts (EE) and ash retention increased with increase in Lacto acidophilus® inclusion with exception for 250gLacto acidophilus® inclusion (CP, CF, EE). However, it was observed that chickens fed dietary levels of Lacto acidophilus® had the best live weight, dressed weight and dressing percentage compared to the control group. It was concluded that chickens fe Lacto acidophilus® inclusion may as well compete favorably with antibiotics growth promoter fed chickens.     Une expérience a été menée pour évaluer l'efficacité de Lacto acidophilus sur la performance de croissance, les caractéristiques de la carcasse et la digestibilité nutritive des poulets de gril. Deux cent vingt-cinq (225), poussins d'un jour ont été achetés à l'écloserie commerciale locale et ont été répartis au hasard en 5 groupes et chaque groupe avait 3 répliques de 17 poussins dans une conception complètement randomisée. Cinq iso- caloriques et iso-azotés (le 'ME' 2998kcal/kg et le 'CP' 23.21%) démarreur et finisseur de poulet de gril (le 'ME' 2990 kcal/kg et le 'CP' 20.33%) des régimes expérimentaux contenant respectivement 0, 150, 200 et 250 g d'acidophilus lacto® pour le T1-T4 et le T5 contenant de l'Oxytetracycline ont été formulés. Les régimes d'entrée et de finisseur de poulet de gril ont été alimentés de 0-3 et 4-7 semaines, respectivement. Les données obtenues ont fait l'objet d'une analyse de la variance à l'aide du système d'analyse statistique et des différences significatives entre les moyens de traitement et ils ont été séparées à l'aide du test à distance multiple Duncan. Il y avait une différence significative (P<0,05) dans le poids final, le gain de poids, le gain de poids quotidien moyen (le 'ADWG'), la consommation totale d'aliments pour animaux (le 'TFI'), l'apport quotidien moyen en aliments pour animaux (ADFI), le ratio de conversion des aliments pour animaux (FCR) et le gain coût/kg des aliments pour animaux dans les groupes de traitement. On a observé que les poulets nourris oxytet alimentaire (oxytetracycline) ont eu les meilleurs résultats en termes de poids corporel final, gain de poids et de 'ADWG', mais similaire à ceux nourris 150 et 200g Lacto acidophilus® niveaux d'addition. Le pourcentage de matière sèche (le 'DM'), de protéines brutes (le 'CP'), de fibres brutes (le 'CF'), d'extraits d'éther (le 'EE') et de rétention de cendres a augmenté avec l'augmentation de lacto acidophilus® l'inclusion à l'exception de 250 glacto acidophilus® inclusion (CP, CF, EE). Cependant, il a été observé que les poulets nourris à des niveaux alimentaires de Lacto acidophilus® avaient le meilleur poids réel, le poids habillé et le pourcentage de vinaigrette par rapport au groupe témoin. Il a été conclu que les poulets feLacto acidophilus® inclusion peut aussi bien rivaliser favorablement avec les antibiotiques promoteur de croissance nourris poulets.
