The study was conducted to investigate the potent capacity of selenium to curtail the adverse  effects of heat stress in broiler chickens. A total of 256, day old Cobb 500 broiler chicks were  randomly allotted to four experimental treatments (0, 0.1, 0.2 and 0.3 mgSe/kg), with four  replicates in a completely randomized design. Initial weight, daily feed intake, daily weight  gain, final weight, feed conversion ratio, daily water intake, feed cost/kg gain, mortality,  serum cortisol and thyroxine levels, calcium, phosphorus and ash levels in tibia bone and  faeces and weight, length and robusticity index of tibia bone were determined. Results  indicated that Initial weight, daily feed intake, daily weight gain, final weight, feed  conversion ratio, daily water intake and mortality were similar (p>0.05) across the treatment  groups and feed cost/kg gain was lower in broilers birds fed 0.3 mgSe/kg. Selenium  supplementation at 0.1 and 0.2 mgSe/kg lowered (p<0.05) cortisol and increased (p>0.05)  thyroxine level, respectively. Mineral deposition in tibia bone was similar (p>0.05), calcium  excretion was higher (p<0.05) in the control group and higher phosphorus was observed in  the faeces of broilers fed the control diet, 0.1 and 0.3 mgSe/kg. Tibia measurements were  similar (p>0.05) in all treatments.     L'étude a été menée pour étudier la puissante capacité du sélénium à réduire les effets  néfastes du stress thermique chez les poulets de chair. Un total de 256 poussins de poulets  Cobb 500 âgés d'un jour ont été attribués au hasard à quatre traitements expérimentaux (0,  0.1, 0.2 et 0.3 mgSe / kg), avec quatre réplicats dans un plan complètement randomisé. Poids  initial, apport alimentaire quotidien, gain de poids quotidien, poids final, taux de conversion  alimentaire, apport quotidien en eau, coût de l'aliment / gain de kg, mortalité, taux de cortisol  et de thyroxine sériques, taux de calcium, de phosphore et de cendres dans les os et les fèces  du tibia et poids, la longueur et l'indice de robustesse de l'os du tibia ont été déterminés. Les  résultats ont indiqué que le poids initial, l'apport alimentaire quotidien, le gain de poids  quotidien, le poids final, le ratio de conversion alimentaire, l'apport quotidien en eau et la  mortalité étaient similaires (p> 0.05) dans les groupes de traitement et le coût de  l'alimentation / gain en kg était plus faible chez les poulets de chair nourris 0.3 mgSe / kg. Une  supplémentation en sélénium à 0.1 et 0.2 mgSe / kg a abaissé (p <0.05) le cortisol et augmenté  (p> 0.05) le taux de thyroxine, respectivement. Les dépôts de minéraux dans l'os du tibia  étaient similaires (p> 0.05), l'excrétion de calcium était plus élevée (p <0.05) dans le groupe  témoin et une plus grande quantité de phosphore a été observée dans les fèces des poulets de

A feeding trial was conducted to evaluate the performance, serum, lipid, haematology and economic indices of broiler chickens fed diets supplemented with different levels of Chestnut (Castenea sativa) phytobiotic as a replacement for antibiotic growth promoters (AGPs). A total of 300, oneday-old cobb 500 broiler chicks were allotted in a completely randomized design to five dietary treatments each replicated thrice, with 20 chicks per replicate. Chestnutphytobiotics was included at 0, 100, 125 and 150g/100 Kg diet while Oxytetracycline was included at 111g/100kg diet. Data was collected on growth performance, haematology, serum biochemical parameters, lipid profiles and economic indices. All data collected were subjected to analysis of variance and significant differences among treatment means were compared using the Duncan's Multiple Range Test of significance. At the end of the starterphase, result showed that chicks placed on 100g phytobiotics diet had significantly (P<0.05) high final weight and weight gain than other supplemented diets and control. There was significant (P<0.05) differences in the feed conversion ratio. Feed cost per kilogram gain was significantly lower in chicks fed control diet, followed by phytobiotics, however higher feed cost per kilogram gain was recorded for chicks fed diet containing Oxytetracycline. Weight gain was significantly (P < 0.05) higher on oxytetracycline based diet (1783.2g) for finisher phase however, there was an improved values for chicks placed on phytobiotics. Glucose (206.51mg/dL) was significantly higher in treatment diet that contained oxytetracycline. Haematological indices showed that values for white blood cell (91.90x103/μL) and Heterophils (20.63%) were significantly higher in diets containing oxytetracycline than other treatment groups. Values for red blood cell, monocytes, eosinophils and basophils were significantly (P<0.05) higher in broiler chickens fed diets containing 100g phytobiotics . Chestnut phytobiotics reduced the total cholesterol values from 151.13 - 96.55mg/dL when compared to other treatment groups. There were significant(P<0.05) differences in all the villi morphometry parameters measured except for crypt depth. The mean yield cost decreased as the level of phytobiotics increased. In conclusion, supplementation of Chestnut phytobiotics reduced total cholesterol and significantly improved the final weight, weight gain, feed cost per Kg gain and feed conversion ratio for both starter and finisher at 100g/100Kg. Chestnut phytobiotic is therefore a potential replacement for antibiotic growth promoters.

 This experiment was conducted to determine the effect of dietary utilization of baobab leaf meal (BLM) on performance, carcass characteristics and hematological parameters of broiler chickens. Two hundred and twenty-five (225), one day old broiler chickens (Marshall Breed) were used for the study. Five diets were formulated containing baobab leaf meal (BLM) at dietary levels of 0, 2.5, 5, 7.5 and 10% designated as T1, T2, T3, T4 and T5 respectively. Chicks were randomly allotted to treatments in a completely randomized design (CRD) and each treatment was replicated three times consisting of 45 broiler chickens with 15 chicks per replication. The experiment lasted for eight weeks. Sample of BLM, experimental diet and faeces were analyzed for proximate compositions. Similarly, levels of anti-nutritional factors in BLM were also evaluated. The results at starter phase showed that the final body weight, daily weight gain and total weight gain were significantly (P < 0.05) higher at 7.5% BLM diet compared to other treatments. The feed conversion ratio (3.30) and feed cost in naira per Kg gain (N257) were significantly (P< 0.05) better at 7.5% BLM diet compared to others. The same trend was observed at finisher phase in the final body weight (2147.80g) and daily weight gain (52.39g). Similarly, feed conversion ratio (3.14) and feed cost in naira per Kg gain (N289.89) were significantly (P< 0.05) better at 7.5% BLM diet compared to other treatments. The results for carcass analysis showed that there were significant differences (P < 0.05) in final live weight (2.15 Kg) as broiler chickens fed 7.5% BLM diet had significantly (P< 0.05) highest values of carcass weight (1.52 Kg) and dressing percentage (72.04%). There were significant differences (P<0.05) in thigh muscle, back and small intestinal weights in which 7.5% BLM diet had the highest values across the treatments. Most of the organs weights were not significantly (P>0.05) affected by BLM inclusion with exception of crop and proventriculus. Therefore, it was concluded that BLM can be incorporated in the diet of broiler chickens up to 7.5% level without any adverse effect on the performance, carcass yield with concomitant reduction in the cost of production

This study was conducted to determine the effect of Ocimum gratissimum as a phytogenic feed additive (PFA) on growth performance, carcass, and blood profile of broiler chicken. One hundred and sixty day old broiler chickens were used for the study. Four diets were formulated to incorporate Ocimum gratissimum at 0, 50, 100 and 150 g per 100 kg of feed to form T1, T2, T3, and T4 respectively. The birds were divided into four groups of forty birds and each group was assigned one of the diets in a completely randomized design. Each group was further divided into four replicates of 10 birds each. Feed and water were supplied ad libitum and data collected were statistically analyzed. The result obtained showed significant (p<0.05) differences in the final weight gain (FWG), daily weight gain (DWG) and feed conversion ratio both at the starter and finisher phases. T4 had the highest significant (p<0.05) final weight gain (FWG), and daily weight gain (DWG) values. The lowest significant (p<0.05) feed conversion ratio (FCR) values were observed in T4. The feed intake of the birds was statistically similar (p>0.05) at both the starter and the finisher phases. Significant (p<0.05) increases were observed in dressed weight, dressing percentage, and cut-up parts (wing, thigh, drumstick, and breast) of the birds. T4 had the highest significant values for the carcass parameters. The haematological parameters analyzed showed significant (p<0.05) differences in the value for red blood cell (RBC), haemoglobin (Hb) and packed cell volume (PCV) values with T4 recording the highest significant (p<0.05) values for those parameters. All the serum biochemical parameters analyzed were not significantly affected (p>0.05) by the treatments. It can be concluded that Ocimum gratissimum could be added to broiler diet at 150 g/100kg as feed additive without any deleterious effect on the growth performance, carcass, and blood profiles of the birds.

The present study was conducted to determine the effect of silicon oxide in broiler chickens drinking water on performance and litter quality. A total of 120, one-day old mixed sex broiler chicks were randomly divided into 4 treatments and 3 replications, with 10 birds in each replicate in a completely randomised experimental design, with 4 silicon levels (0.00, 1.50, 2.00 and 2.50 mg of silicon oxide/litre of water. Corn-soya based diets were formulated at the starter (0–4 weeks) and finisher (5–8weeks) phases and were supplied ad libitum with free access to water. The average daily temperature and relative humidity inside the poultry house were 35.9 °C and 36%, respectively. At the starter phase, chicks administered 2.00mg silicon oxide/litre of water had significantly (p<0.05) higher final body weight (991.00g) and average weight gain (950.96g) compared to chicks without silicon oxide 778.57 g and 738.54g. The inclusion of 2.00 mg silicon oxide/litre of water improved feed conversion ratio compared to the control group (p < 0.05) and significantly reduced feed cost per kg gain. For the finisher phase, chickens administered 2.00mg silicon oxide/litre of water had the best results for final weight, weight gain and feed cost per kg gain. Also, inclusion of silicon oxide in broiler chickens water improved litter quality as predominantly dry material but with some areas of wet shavings was observed. In conclusion, silicon oxide in broiler chickens drinking water at 2.00mg/litre of water enhanced growth performance, improved feed conversion ratio and litter quality as well as reduced feed cost per kg gain at the starter and finisher phases respectively.

The aim of this research was to evaluate the effect of biochar diet supplementation for broiler chickens on (1) ammonia and odor emissions from manure, (2) feed conversion ratio and daily weight gain, and (3) selected meat quality and sensory parameters. Beechwood biochar (BC, 2 and 4%) and BC–glycerin–aluminosilicates mix (BCM, 3 and 6%) were tested as dietary additives. A total of 750 chicken broilers (Ross 308) were divided into five dietary groups with five replicates per group (n = 5, 30 birds in each replicate) and reared on a littered floor for 5 weeks. Both feed additives showed a significant reduction of ammonia emissions by up to 17%, while the reduction of odor emissions was not statistically significant. The feed conversion ratio increased by 8% for the highest concentration of the mixture. The change of the treated broilers’ average body weight ranged in the last week of the experiment from 0 to −7%, with the most negative effect for the highest dose of the mixture. Sensory analysis of the sous-vide cooked breasts showed no significant differences.

This study was conducted to investigate the effect of dietary copper and probiotic supplementation on growth performance and carcass characteristics of broiler Chickens. A total of 180-day old marshal broiler chicks of mixed sex were randomly allotted to six treatment groups of 30 birds each. The Treatments were divided into three replicates of ten birds each; starter and finisher diets were formulated and fed for a period of fifty-six days. The dietary treatments were subjected to completely randomized design experimental layout which was made up of probiotic (0 and 500ppm) and copper (0, 125 and 250mg).The chicks were fed the broiler starter diet for the first 28 days and broiler finisher for the last 28 days. Treatment effect on broiler body weight, feed intake and feed conversion ratio were determined on a weekly basis. Data obtained were analyzed using analysis of variance (ANOVA) and, Duncan's Multiple Range Test was used to separate significant means. Dietary supplementation of copper and probiotic had no significant (P> 0.05) effect on final weight (FW), daily weight gain (DWG), feed intake (FI), and feed conversion ratio (FCR) at the starter phase of the experiment. However, at finisher phase, inclusion of probiotic resulted in higher significant (P < 0.05) values for FW (2214.12g/b) DWG (60.22g/b/d), FI (159.02g/b/d), and FCR (2.64). The carcass yields of the broilers were significantly (P< 0.05) influenced by copper and probiotic supplementations. However, lower value (1.07%) was obtained for abdominal fat in broilers fed 250mg Cu/kg supplemented diet. The study concluded that supplementation of copper and probiotics resulted in improved growth performance and carcass yield of broiler chickens.

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

A 42-day feeding trial was conducted to investigate the performance characteristics and cost benefit of feeding weaner rabbits cashew nut residue (CNR) based diets. Three dietary treatments containing: 0.10 and 20% CNR at the expense of maize on a weight for weight basis were used. Eighteen weaner rabbits (mixed breeds and sexes) were randomly divided into three groups of six rabbits each in a completely randomized design (CRD). The average daily weight gain, average daily feed intake and feed conversion ratio were not significantly influenced (P>0.05) by the dietary treatments. But rabbits fed 10% CNR based diet had the highest values for average daily weight gain and average daily feed intake while rabbits fed the control diet (0% CNR) had the least value for feed conversion ratio. No mortality was recorded for all the dietary treatments. The feed cost/kg diet (₦), feed cost/kg live weight gain (₦/kg) and cost of feed consumed/day (₦) decreased steadily with increasing level of cashew nut residue meal. The saving on feed cost (%) was not significantly affected (P>0.05) by the dietary treatments, but increased across the groups. However, the saving on feed to produce 1kg live weight was significantly (P<0.05) influenced by the CNR based diets. Rabbits fed 10% CNR based diet had the highest value of 9.66% than their counterparts fed other diets. It is concluded that cashew nut residue could be incorporated into rabbit diet at 10% without compromising the performance
