The present study was conducted to investigate the effects of using probiotic <em>Yeasture</em>® at different rearing periods on performance, intestinal microbial population and carcass traits in broiler chickens. A total of 378 one day old chickens (male and female) were randomly allotted to one of the 21 floor pens in a completely randomized design with seven treatments and three replicate groups and eighteen chickens in each group (9 male and 9 female). The Experiment treatments consisted of seven groups: A (control, without probiotic), B (prebiotics feeding between 1 to 10 days), C (prebiotics feeding between 1 to 24 days), D (prebiotics feeding between 1 to 42 days), E (prebiotics feeding between 11 to 24 days), F (prebiotics feeding between 11 to 42 days) and G (prebiotics feeding between 24 to 42 days). The chickens received the desired probiotic at different days of rearing period. The basal diets were corn and soybean meal, so 0.3 g/kg of basal diets in starter (1-10 days), 0.25 g/kg of basal diets in grower (11-24 d) and 0.2 g/kg of basal diets in finisher (24-42 d) period of probiotic was added to the basal diets for each other than treatment. The growth performance (evaluated through body weight gain, feed intake and feed conversion ratio), intestinal microbial population (the measurement of <em>Lactobacillus</em> and <em>Coliforms</em>) and carcass traits (relative weights of carcass, intestine, liver, gizzard and abdominal fat) were determined. Body weight gains and feed conversion ratio were significantly improved in broilers with added probiotic compared to the control group (P&lt;0.05) whereas feed intake was not significantly altered. In addition, intestinal microbial population and carcass and gizzard weights markedly increased in the probiotic treated birds compared to control chickens (P&lt;0.05). These results show that diet supplementation with probiotic <em>Yeasture</em>® at the early days of the rearing periods of broiler chickens especially, 1 to 24 and 1 to 42 days, had a positive effect on intestinal microbial population, leading to more nutrients being assimilated by the chickens and consequently greater performance in broiler chickens.

Feed Conversion

One method of reducing feed cost is to restrict the feed in the early life of broilers. In this regard, Fontana et al. (1992) reported that early feed restriction programs in their experiments proportionally reduced the consumption of the starter diets by an average of 22% in restricted broilers when compared with controls. Energy restriction has also been shown to result in a reduction in metabolic energy loss leading to a reduced requirement for maintenance. If during refeeding, this low requirement is maintained and if growth resumed at a normal or above normal rate (compensatory growth), feed efficiency would be substantially improved, leading to an economical advantage. This experiment was conducted to determine the effect of severity of diet dilution (energy and protein) and duration of early feed restriction on feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR) of male broiler chickens.

SummaryA total of 432, one-day-old broiler chickens were randomly assigned as a 2 × 4 factorial design (pellet or mash and 0, 25, 50, and 75% whole sorghum levels) in a completely randomised experiment, having six replicates with nine birds per replicate. Body weight and feed intake were measured on a pen basis at 10, 25, and 35 days of age and feed conversion ratio calculated. Pelleting diets significantly improved (P<0.05) feed intake, body weight and carcass yield of broiler chickens at 10 and 24 days of age. Heavier relative gizzard weights with lower pH (P<0.05) were recorded for broiler chickens offered mash diets at 35 days old. Feed conversion ratio at 35 days of age increased (P<0.035, quadratic effect) with higher levels of whole sorghum and levelled off at 75% inclusion rates. Relative gizzard weight at 35 days was marginally increased (P<0.033, linear effect) in line with rising sorghum levels. Similarly, relative bursa and liver weights at 35 days increased (P<0.037, quadratic effect and P<0.033, linear effect, respectively) with sorghum inclusion. The results showed that pelleted diets gave superior performance compared to mash diets. Although higher levels of sorghum inclusion in mash diets enhanced gizzard development, performance parameters of birds at 35 days of age were poorer, with 125 g less body weight and an increase in FCR from 1.51 to 1.62 for the 0% and 75% sorghum levels respectively.

The objective of this study was to investigate whether melamine (MEL) is biotransformed into cyanuric acid (CYA) in male broiler chickens. The effects of the dietary addition of MEL and CYA alone and in combination on the growth performance and mortality of the chickens were also investigated. The chickens were divided into six experimental groups and were fed diets with an addition of 50 or 100 mg/kg MEL or 50 or 100 mg/kg CYA of diet, with the contaminants added separately or in combination. The control group was fed a diet without MEL or CYA. At the end of the experiment (day 40), samples of liver, kidney and breast and thigh muscles were collected from 12 birds per treatment group and were analysed for the presence of MEL and CYA. This study showed that MEL is biotransformed into CYA in broilers. Higher concentrations of MEL or CYA in the diet increased the presence of their residues in tissues, and the CYA residue concentration was several times higher in the respective tissues than the MEL residue concentration. The dietary addition of MEL and CYA did not affect the mortality rate, feed conversion ratio or body weight of the chickens.

Growth Promoting

One of the widespread spices is garlic which consumed by people of different parts of the world but its valuable growth promoting effect is not sufficiently studied in poultry. Growth promoting effect of garlic in broiler chickens was studied together with its carcass characteristics and blood parameters. Broilers were grouped into four: A (1%), B (2%), C (positive control) and D (negative control).  Aqueous extract of garlic (1% and 2%) was prepared by extraction and were administered with drinking water. A group (1%) shows best performance with regards to body weight gain rather than B (2%), positive and negative control. At the end of experiment (35th day), in A group, the live body weight, dressed weight, feed conversion ratio, liver, gizzard, heart, spleen, and pancreas were 1833.2±2.1g (P<0.05), 1229.7±1.9g (P<0.05), 1.63(P<0.05), 47.13±0.4g, 26.15±0.7g, 9.71±1.8g, 2.21±0.2g, 2.27±0.1g respectively. The mean Total Erythrocyte Count (TEC), Haemoglobin concentration (Hb) and Packed Cell volume (PCV) were 2.9± 0.1million/cm3,7.5g ± 0.2g, and 25.8 ± 0.6%, respectively. It is recommended that 1% aqueous extraction of garlic shows better growth and improved carcass qualities in broilers.

Considering the inherent attributes of tannia cocoyam (Xanthosoma sagitifolium) its appropriate utilization may enhance performance of starter broiler chicks. This study was therefore carried out to determine the dietary evaluation of starter broiler chicks fed cooked cocoyam tuber meal as energy source in place of maize. The cooked cocoyam tuber meal was used to replace maize at various levels of 25%, 50%, 75% and 100% respectively for diets 2, 3, 4 and 5 to determine the best replacement level that would give optimal performance in starter broiler chicks' diets. Result of the proximate composition of cooked cocoyam tuber meal showed that it contained 13.11% moisture, 2.60% ash, 1.85% ether extract, 3.90% crude protein, 9.45% crude fibre, 70.13% nitrogen free extract and 3004.37 Kcal/kgME. 150 day old Anak broiler chicks were used for the experiment. They were divided into 5 treatment groups of 30 broiler chicks each. Each treatment group was subdivided into 3 replicates of 10 broiler chicks each and kept in deep litter. Each starter diet was fed to a group of 30 starter broilers for 4 weeks using completely randomized design. They were given feed and water adlibitum. Parameters measured include initial body weight, final body weight, body weight gain, feed intake, feed conversion ratio and economics of production. In the starter broiler feeding trial, the starter broilers on 25% cooked cocoyam meal compared favourably with the control (P> 0.05) in terms of feed intake, body weight gain and feed conversion ratio and significantly (P > 0.05) performed between than those on 100% CCYM. The cost of production (N/Kg broiler) was however cheapest for diet 2 (25% CCYM) N395 versus control diet (N494.28). It was therefore concluded that cooked cocoyam tuber meal (Xanthosoma sagitifolium) could be used in the diets of starter broiler chicks' up to 25% without affecting the body weight gain, feed intake and feed conversion ratio as indicated in this study.

An experiment was conduct in order to investigate the effects of feed restriction level and duration and dietary coenzyme Q10 level on growth performance, organ characteristics and plasma lipoproteins. A factorial arangment based on a completely randomized design was performed using two levels of feed restriction (10 and 20% less than the standard Ross strain 308 guidelines), two levels of restriction duration (7 and 14 days) and three levels of coenzyme Q10 (0, 20 and 40 mg/kg feed). The results of the experiment showed that restriction intensity had significant effect on feed intake in first, second and sixth weeks of age (P<0.05), body weight gain in second and sixth weeks of age (P<0.05), and feed conversion ratio in first week of age (P<0.05). Restriction duration had significant effect on feed intake in third week of age (P<0.05), and feed conversion ratio in third and sixth weeks of age (P<0.05). Coenzyme Q level had significant effect on feed intake in first and sixth weeks of age (P<0.05), body weight gain in second, fifth and sixth weeks of age (P<0.05), and feed conversion ratio in second and sixth weeks of age (P<0.05).  In conclusion, considering the positive effects of feed restriction and coenzyme Q10 on broiler yield, the simaltaneous use of feed restriction strategy and dietary coenzyme Q10 can be considered as a management program in order to improvement of broiler productivity.

Considering the inherent attributes of cocoyam tuber meal (Xanthosoma Sagitifolium), its appropriate utilization for chicken diets may enhance performance of broiler chicken. This studywas therefore carried out to determine the nutritional evaluation of fermented cocoyam tuber meal as energy source in the diets of starter broilers production. The fermented cocoyam was used to replace maize at various levels to determine the best replacement would give optimal performance in starter broilers diets. One hundred and fifty 150 day old Agrited starter broilers were used for this experiment,. The proximate composition of fermented cocoyam tuber meal (FCYM) showed that it contained 19.5% moisture, 1.30% ash, 3.56% Crude protein, 5.30% crude fibre, 1.9% ether extract and 25.48% NFE. In the starter feeding trial, the fermented cocoyam was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each starter diet was fed to a group of 30 broilers chicks for four weeks using completely randomized design. Each treatment was divided into three replicates of 10 broiler chicks each. Parameters measured include initial body weight, final body weight, body weight gain, feed intake, feed conversion ratio and cost of production. In the starter feeding trial, the starter broilers on 25% FCYM compared favorably with those on the control diet (P>0.05) in terms of feed intake, feed conversion ratio and body weight gain and hence recorded the higher body weight gain. The cost per kg feed produced was N182.50 for the control diet and the lowest was diet 5 (100% FCYM) which was N82.74. The cost of production (cost/kg feed x feed conversion ratio) of starter broilers per kg body weight gain was lowest for diet 5 (100% FCYM) (N158.86), while the costliest was those on the control diet (N383.25). The results of the trial have shown that fermentation of cocoyam tuber meal for 4 days for formulating starter broiler diets was quite an effective method of processing because fermentation reduced the anti-nutrients content. It was concluded that fermented cocoyam tuber meal could be used in the diets of starter broilers up to 25% without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.
