The objective of the present study was to determine the effect of dietary supplementation of neem oil (Azadirachtaindica) on the growth performance and nutrient digestibility of weaned rabbits. A total of 50 weaned male cross bred rabbits between 5-6 weeks with an average weight of 565.4g-566.8gwere divided into five dietary groups of ten (10) weaned rabbits each in a completely randomized design. The dietary treatments include a control, T1 (basal) diet with no neem oil (NOL), T2, T3, T4 and T5 were fed basal diet supplemented with NOL at 0.1%, 0.2%, 0.3% and 0.4% respectively. Feed and water were offered ad libitum throughout the experiment which lasted for 12 weeks. The data obtained was used to evaluate the growth performance: weight gain (WG), feed intake (FI), feed conversion ratio (FCR), mortality and nutrient digestibility (dry matter, crude protein, crude fibre and ether extract). WG, ADFI, TFI were significantly (P˂0.05) different among the treatments. T5 had the highest weight gain (755.90 g) followed by T4(734.0g), T3(705.90g), T2(705.0g) and T1(621.80g) respectively. Highest mortality was recorded in T1 (2%) followed by T2 (1%), none was recorded in T3, T4 and T5. Neem oil significantly influenced (P˂0.05) all the parameters measured. It could be concluded thatneem oil contains some essential nutrients and bioactive chemicals and could be supplemented in the diet of rabbit at 0.4 % without any deleterious effect on the general performance of the animal.

The potentials of non-conventional resources are great as they play an important role inalleviating the problem of cost and competition of conventional feed sources for livestock and poultry in Nigeria. This study aimed at investigating the growth performance of weaner rabbits fed graded levels of plantain leaf (PL). Thirty mixed bred rabbits aged 6-8 weeks old with an average weight of 0.70 ± 0.02 kg were randomly allotted to five experimental treatments of three replicates each in a completely randomized design. Treatments consisted of T1 – concentrate alone (control), T2 – T5 had 25g, 50g, 75g and 100g of PL respectively. Proximate composition of the feed were carried out while initial weight, final weight, feed intake, feed conversion and weight gain were measured. Results revealed that the crude protein and crude fibre contents of the concentrate and PL recorded 19.30% and 9.97% vs 0.98% and 8.11% respectively. Initially weight ranged from 0.65kg – 0.76kg. Rabbits on T2 recorded the least final weight (0.98kg) which was similar to those on T4 (1.05kg) and T3 (1.10kg) but lower (P<0.05) than those on T5 and T1 (1.32kg and 1.38kg respectively). Rabbits on T5 recorded the highest intake of PL (83.72g/d) while those on T2 had the least (21.04g/d). Weight gain was highest (0.68kg), for rabbits on T1 but least for those on T2 (0.23 kg). The feed conversion ratio ranged from 4.65 (T1) to 14.85 (T4). Rabbits were able to tolerate the plantain leaf meal up to 100g. In addition, rabbits on 100g/day plantain leaf performed comparably with those on control.

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.

This study was carried out to determine the effect of dietary supplementation of melon (Citrallus lanatus) seed oil (WMO) on the growth performance and immune response of growing rabbits. Thirty-six (36), 5-6 weeks weaner rabbit of mixed breed and sex with an average weight of 435 g – 438 grams were randomly divided into four (4) treatments of nine rabbits per group and each rabbit served as a replicate in a completely randomized design (CRD). The experiment lasted for 12 weeks and all other management practices were strictly observed. The basal diet was formulated according to the nutrient requirements of the rabbit according to NRC (1977). Treatment (T1) was fed basal diet with 0 % WMO, T2, T3, and T4 were fed basal diet supplemented with WMO at 0.2 %, 0.4 % and 0.6 % respectively. Results obtained were used to examine the average daily weight gain (ADWG), average daily feed intake (ADFI), feed: gain, mortality, activities of superoxide dismutase (SOD), glutathione-S-transferase (GST), reduced glutathione (GSH), and malonyl dialdehyde (MLA). ADWG, feed: gain, and mortality were significantly different (P˂0.05) among the treatments. ADFI increased as the level of WMO increases, though not at a significant level (P˃0.05). The highest mortality was recorded among animals in T1 (1.00 %), none was recorded in the other treatments (P˂0.05).  Activities of SOD, GST, GSH, and MLA were significantly (P˃0.05) influenced by WMO. It was concluded that dietary supplementation of WMO up to 0.6 % enhanced growth performance, improved feed: gain, and had no negative effect on the antioxidant parameters of rabbits, it is safe and could be used to bridge the gap between food safety and production.

In a bid to decrease cost of production and increase performance in poultry, the study aimed at determining the growth performance and haematological characteristics of pullet chicken fed different feed forms supplemented with or without oyster mushroom (OM), three hundred and twenty (320) day old Harco Black pullet chicks were brooded for five weeks before they were allocated based on weight equalization on the basis of feed forms (mash and pellet) and OM supplementation (without and with 1g of OM per kg of feed) into four (4) treatments for an experiment which lasted for eleven weeks. Each treatment consisting of 80 birds was replicated eight (8) times with ten (10) birds per replicate. Data collected were arranged in a 2 × 2 factorial layout and subjected to Analysis of Variance in a Completely Randomized Design. Final weight, average weight gain and average feed intake in the grower phase were significantly (p<0.05) higher (1244.69g, 11.13g and 106.11 g) in birds given pelletized feed and lower (1146.25g, 9.27g and 105.08 g) in birds fed mash. Also, PCV, WBC, and Hb obtained in the starter phase were significantly (p<0.05) higher (30. 00%, 2.70 x 10 /l and 10.10 g/dl, respectively) in pullet chicken fed diet supplemented with oyster mushroom than those (26.75%, 2.12 x 10 /l and 8.85 g/dl, respectively) recorded by birds fed diets without oyster mushroom. Therefore, improved weight gain, feed conversion ratio, and immunity can be achieved by feeding pullet chickens with pelletized feed supplemented with oyster mushroom.     Dans le but de diminuer les coûts de production et d'augmenter les performances des volailles, l'étude visait à déterminer les performances de croissance et les caractéristiques hématologiques de poulettes nourries de différentes formes d'aliments supplémentées avec ou sans pleurotes (MO), trois cent vingt (320) jours de vieux poussins de poulettes Harco Black ont été couvés pendant cinq semaines avant d'être répartis sur la base d'une égalisation de poids sur la base des formes d'aliments (purée et granule) et d'une supplémentation en MO (sans et avec 1 g de MO par kg d'aliment) en quatre (4) traitements pour une expérience qui a duré onze semaines. Chaque traitement composé de 80 oiseaux a été répliqué huit (8) fois avec dix (10) oiseaux par répliquant. Les données recueillies ont été organisées selon une disposition factorielle 2 × 2 et soumises à une analyse de la variance dans un plan complètement randomisé. Le poids final, le gain de poids moyen et la prisealimentaire moyenne pendant la phase de croissance étaient significativement (p<0,05) plus élevés (1244,69 g, 11,13 g et 106,11 g) chez les oiseaux ayant reçu des aliments granulés et inférieurs (1146,25 g, 9,27 g et 105,08 g) chez les oiseaux. oiseaux nourris de purée. De plus, les PCV, GB et Hb obtenus lors de la phase de démarrage étaient significativement (p<0,05) plus élevés (30,00 %, 2,70 x 109/l et 10,10 g/dl, respectivement) dans le régime alimentaire des poulettes supplémentées en pleurotes que ceux (26,75 %, 2,12 x 109/l et 8,85 g/dl, respectivement) enregistrés par des oiseaux nourris avec des régimes sans pleurotes. Par conséquent, une amélioration du gain de poids, du taux de conversion alimentaire et de l'immunité peut être obtenue en nourrissant des poulettes avec des aliments granulés complétés aux pleurotes.

Abstract Background An effort was made to assess the effectiveness of dietary supplementation of Ulva lactuca (U. lactuca), a seaweed and Azolla individually and in combination on different physiological parameters of Aseel chicken. A total of 40 Aseel chicks of 8 weeks old were allocated into four groups, C1 (control), T1 (Azolla alone), T2 (seaweed alone) and T3 (seaweed plus Azolla). Aseel chicks in C1 were fed with formulated grower feed alone, birds in T1 had control diet with 5% Azolla, birds in T2 had control diet with 3% U. lactuca and birds in T3 had control diet admixtured with 5% of Azolla and 3% of U. lactuca. Parameters were recorded for a continuous period of 2 months in 15 days interval. Results The growth performance was found to be significant (P ≤ 0.05) during 30 days of feed trials and highly significant (P ≤ 0.01) during 45 and 60 days of treatment. Birds in T3 had a higher body weight gain, shank length and feed conversion efficiency followed with T1 and T2 compared to C1. PCV, RBC, WBC and heterophil counts were not influenced (P ≥ 0.05) by dietary treatments. Uric acid, creatinine, AST, glucose, triglycerides and magnesium levels revealed a high significant (P ≤ 0.01) variation, and cholesterol level showed significant (P ≤ 0.05) changes during 30th and 60th day of feed trials between the control and treatment groups. Total protein, globulin, phosphorus and electrolytes like Na, K and Cl levels were not significant (P ≥ 0.05) during 30th day and were highly significant (P ≤ 0.01) during the 60th day of the trial. Conclusions It could be noted that inclusion of U. lactuca and Azolla as feed supplement in grower chicken had a better body weight gain when given in combination (U. lactuca and Azolla) rather than supplemented with the sole entity. Based on the haematological and serum biochemical analysis, the supplementation of U. lactuca and Azolla at the levels included in this trial did not pose any threat to the physiological well-being of Aseel chicken.

The purposes of determining the influence of the light and sexing on growth performance and slaughter results atyoung quails from Balotesti population, was organized an experiment on 150 quails, betwen age of 28 and 70 days. The chicks were divided into two groups (control and experimental), and growth and slaughter performance were determined separately by sex. Have studied 2 lighting programs, a program of continous lighting with photoperiod duration of 16 hours (16 L + 8 N, control group) and a program with lighting with asymetric hours intervals with photoperiod duration of 16 hours (10L+2N+6L+6N, experimental group).Males and females from the experimental group were recorded average performance of growth high during the period 28 - 70 days. Live weight at age of 70 days was higher with 7.54 %, average weight gain was higher with 14.86 % and feed conversion rate was lower with 13.51 % at males from experimental group compared to males from the control group. Also, the live weight at the age of 70 days was higher with 18.09 %; average weight gain was higher with 35.12 %, while feed conversion rate was reduced with 30.08 % on females from the experimental group compared to females from the control group.The results of the slaughter at 70 days were superior in the caseof females from the both groups versus males. The average weight of the carcase was higher with 17.53 % in case of the females than that of males from the experimental group, and the carcase yield was 65.37 % at the females and 65.56 % for males. Also, the average weight of the carcase was higher with 5.08 % in case of females compared to that males from the control group, and the carcase yield was 64.20 % to females 66.70 % on males.Superior results recorded in the case of females and males from the experimental group recommended the program of lighting with asymmetric hours intervals in the growth of youth quail. Also, the higher slaughter results recorded in the case of females of the two groups recommended them in the meat production through a broiler of quail that combine advantages in the production of both males and females.

This study aimed to assess the effects of different levels of Trichanthera gigantea leaf meal (TGLM) supplementation on the growth performance of Philippine Native chickens fed commercial chicken grower ration. A total of 96 three-month old native chickens of two sexes were randomly distributed to the four treatments with 3 replicates and 4 chickens per replicate in a 2 x 4 factorial in Completely Randomized Design (CRD). Under semi-confinement system, the dietary treatments consisted of 0, 5, 10, and 15% levels of TGLM supplementation for 13 weeks. Results revealed that cumulative voluntary feed intake (VFI) increased as TGLM supplementation increased, and was significantly highest with 15% level at weeks 10, 11 and 12. Although differences were not significant except at weeks 4 and 7, there was a decreasing trend in cumulative weight gain (CWG) with increasing TGLM level. Average daily gain (ADG) was not significantly affected by varying levels of TGLM supplementation, and feed conversion efficiency (FCE) showed a decreasing trend as TGLM level increased and was only significantly low (p<0.01) with 15% level at week 7. Comparing between sexes, the males were significantly higher than females in all production performance parameters. Therefore, TGLM is palatable but not adequate enough to supply the nutrients needed for a comparable weight gain with that of 0% supplementation, and a 5 10% inclusion in the diet is recommended.

This study was aimed to determine the effects of protease supplementation in diets with agricultural-livestock by products on the growth performance in broiler chickens. The commercial protease used in current study was produced by Bacillus licheniformis which based on keratinase. The treatment diets were a control basal diet without agricultural-livestock by-products and protease supplementation (P1); P1 + 0.05% protease; basal diet with meat bone meal (MBM) and distiller’s dried grain with soluble (DDGS) suppementation (P3); P3 + 0.05% protease (P4); basal diet with hydrolized chicken feather meal (HCFM) and DDGS supplementation (P5); P5 + 0.05% protease. The obtained data were statistically analyzed using Complete Randomized Design, and analyzed subsequently by Orthogonal Contrats Test. Results showed that protease supplementation in the diets containing agricultural-livestock by-products did not affect growth performance of broiler chickens in starter phase and overall age phase. However, in diets containing MBM, protease supplementation reduced the nett gain and feed conversion ratio (FCR) in finisher phase (P<0.05). In diets containing HCFM, protease supplementation increased nett gain and FCR (P<0.05), compared to those of containing MBM. It could be concluded that qualified HCFM, MBM, and DDGS can be used as alternatives for protein-energy source feed stuffs in starter phase, as they did not reduce growth performance of broiler chickens. Protease used in this study might be more effective in diets containing HCFM than those of containing MBM and DDGS.Keywords: Agricultural-livestock by-products, Broilers chickens, Growth performance, Protease.

The present study was conducted to evaluate the effect of different levels of methionine supplementation on feed intake, nutrient digestibility and growth performance of growing rabbit. Sixteen weaned crossbred New Zealand White (NZW) growing rabbits (30-35 d) were distributed into four treatment groups having four replications in each group using a Completely Randomized Design (CRD). Basal diet composed of green grass (dhal grass) and concentrate mixture which was offered ad libitum basis for 56 days period. Four levels of methionine such as 0.0% (control), 0.15%, 0.25%, and 0.35% were supplemented randomly to rabbits. Results showed that supplementation of methionine did not affect green grass intake. Cumulative as well as daily concentrate and DM intake were significantly (p<0.05) higher for all methionine groups than control group. Final body weight gain as well as daily, weekly and cumulative body weight gains were improved significantly with increasing level of methionine. It was found that methionine had significant (p<0.01) effect on digestibility of DM, CP, NFE and EE but CF digestibility did not differ significantly. Digestibility was improved with increasing the level of methionine. Feed conversion ratio also decreased significantly with methionine supplementation, and 0.25% methionine group showed the best performance among the four treatments.
