Broiler Feed

The experiments were carried out on 5 groups of cage housed broiler chickens of the Ross 308 cross aged from 1 to 35 days. It was found that dried chicory root, oregano, and common nettle are valuable additives in compound poultry feed. The addition of dried chicory root, oregano, and common nettle in amounts of 2 kg/t; 0.5 kg/t, and 2.0 kg/t, respectively, to broiler diets allows obtaining good livability (100%) and live bodyweight, as well as low feed conversion. In the experimental groups the dried medicinal plants were added to the feed without the use of in-feed antibiotics. It was statistically proven that the live bodyweight in broilers at the end of growing in the experimental groups was significantly in compare to control by 7.08-8.04%. This increase was accompanied by a decrease in feed conversion ratio by 10.33-10.45% due to improved digestibility and retention of dietary nutrients. With the introduction of dried medicinal plants into broiler feed, an increase in the protein content in the pectoral muscles by 1.31-1.56% and a decrease in fat content by 2.23-2.97% were found. The sensory quality of the roasted meat was good.

A preliminary study was carried out to determine the prevalence of Aflatoxin B1 (AfB1) contamination and common moulds growing in some selected poultry feed raw materials in Zaria. Five different feed raw materials:Maize (MZ), soybean cake (SBC), groundnut cake (GNC), brewers dried grain (BDG) and maize offal (M/O), were collected from four feed mills and the open market. The common moulds isolated from the samples were Mucor spp., Aspergillus spp., Fusarium spp., Penicillum spp., Curvularia spp. and Rhizopus spp. AfB1 contamination showed that maize and soya bean cake were less than the 20 parts per billion (ppb) permissible limits for AfB1 in poultry feed ingredients, while BDG, M/O and GNC were 40, 60 and 80 % respectively above 20 ppb permissible limits. A feeding trial was conducted to evaluate the response of broiler chickens to Mycofix a toxin binder. Three hundred and thirty Ross, 1-day old broiler chicks were assigned to five dietary treatments, each with three replicates of 22 chicks per replicate in a completely randomized design (CRD). Treatment 1 was the control diet without Mycofix while treatments 2, 3, 4 and 5 had Mycofix included at 100, 200, 300 and 400 g /100kg diet, respectively at both starter and finisher phases. Experimental diets and water were given to the birds ad libitum during eight weeks of the feeding trial. Data were subjected to Analysis of Variance (ANOVA) using General Linear Model procedure of SAS and significant differences among treatment means were compared using Dunnette test of significance. Results of the starter phase showed that birds fed 400 g/100kg Mycofix diet had the best final body weight (902.67g), weight gain (839.67g) and average daily weight gain (29.98g). Birds fed 200 g /100 kg Mycofix had the lowest feed conversion ratio of 1.6  and the least cost per  kilogram gain(₦138.52).At the finisher phase birds on 400 g/100kg Mycofix diet had the best final weight (2345.3g), weight gain (1403.3g), average daily gain (50.1g), feed conversion ratio (2.1) and least feed cost per kilogram gain (₦167.20). It may be concluded that addition of Mycofix to diets of broiler chickens at 400g/ 100kg at both starter and finisher phases of the study improved performance significantly and gave the least cost of production.

We evaluated the influence of enzymatic supplementation on the growth performance and cecal microbiota of broilers. A total of 2160 1-day-old male chicks were used in a 3 × 2 × 2 factorial arrangement (three corn hybrids, two drying temperatures −80 and 110 °C, with or without the inclusion of an enzymatic blend (amylase, xylanase, and protease) (20 birds/pen, n = 9). For all performance and digestibility parameters, we observed, in general, isolated effects of the corn hybrids and drying temperature. Birds that received the enzymatic blend in the diet showed better weight gain from 1 to 21 days (d) and better digestibility coefficients of nutrients at 42 d. Birds fed diets with corn dried at 80 °C showed a better feed conversion ratio from 1 to 42 d. At 21 d of age, enzymatic supplementation had positive effects on jejunum morphology. Enzyme supplementation increased the abundance of the phylum Tenericutes, class Bacilli and Mollicutes, reduced Clostridia, and increased the abundances of the families Lactobacillaceae, Anaeroplasmataceae, and O_RF39;F. In conclusion, the addition of amylase, xylanase, and protease led to a better nutrient digestibility, performance, and intestinal morphology. In addition, enzyme supplementation changed the diversity, composition, and predicted function of the cecal microbiota at d 21.

Two experiments were conducted to study the effects of either soluble or insoluble fibre naturally occurring in wheat and oats, on technical pellet quality and nutritional value for broiler chickens. In exp. 1, the effects of insoluble fibre were studied by mixing diets based on wheat or naked oats with either coarse or fine oats hulls followed by pelleting. Hull inclusion increased (P < 0.05) starch gelatinisation, especially in the diets based on oats. Addition of finely ground oats hulls improved pellet durability, in particular after storage, while no such effect was observed for coarse oats hulls. Oats hulls inclusion caused a more elastic pellet with higher breaking resistance (P < 0.05). Lower (P < 0.05) energy consumption was observed for diets based on oats compared with wheat, while no effect of fibre inclusion on energy consumption was found. In exp. 2, the influence of pelleting on the viscosity effect of soluble fibres in diets based on wheat or oats was studied. A significant increase (P < 0.05) in intestinal viscosity of broiler chickens was observed for all batches of grain exposed to steam pelleting. Viscosity was doubled (P < 0.05) with wheat diets, while the increase in viscosity was even greater in oat diets. In wheat diets, feed intake and weight gain was reduced (P < 0.05), while feed conversion ratio was not affected. Steam pelleting of oats reduced (P < 0.05) feed intake and weight gain, and increased feed conversion ratio (P < 0.05). The improvements (P < 0.05) in metabolisable energy and dry matter digestibility in wheat diets was not consistent with the observed increases in viscosity or with the results obtained with oats. Key words: Soluble fibres, insoluble fibres, viscosity, starch gelatinisation, steam-pelleting

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.

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.
