Abstract An experiment was conducted to determine the effects of L-Lys HCl inclusion in diets with or without distillers dried grains with solubles (DDGS) on growth performance of finishing pigs. A total of 2,414 pigs (initial BW = 92.7 kg) were used in a 34-d trial. Treatments were arranged as a 2 × 3 factorial treatment structure with two levels of DDGS (0 or 10%) and three levels of L-Lys HCl (0.2, 0.3, or 0.4%). Diets were corn and soybean meal-based and were formulated to be isocaloric (NE = 2,668 kcal/kg) and isolysinic (0.75% SID Lys) by adjusting the inclusion of soybean meal, crystalline amino acids, and choice white grease. All other nutrient levels met or exceeded the NRC (2012) requirement estimates. There were 16 replicates per treatment. Pigs were weighed and feed disappearance measured to calculate ADG, ADFI, and G:F. Data was analyzed with SAS MIXED procedure. There was no evidence (P > 0.10) for interactive effects between L-Lys HCl and DDGS inclusion rate. Pigs fed diets with 10% DDGS had improved (P = 0.002) G:F, but there was no evidence (P > 0.10) for differences in ADG or ADFI. Pigs fed increasing levels of L-Lys HCl had higher (linear, P = 0.026) ADFI, decreased (quadratic, P = 0.013) G:F, and a tendency for quadratic response (P = 0.063) in ADG, overall with the poorest performance observed for pigs fed the diet with 0.4% L-Lys HCl. In conclusion, pigs fed 0 or 10% DDGS presented similar performance; however, pigs fed the high level of L-Lys HCl presented decreased performance.

The objective of this study was to determine the effects of chlorogenic acid (CA) and bamboo charcoal particles activated by microwave (BCP) on performance, serum urea nitrogen and husbandry environment of broilers. The diets were devoid of antibiotic growth promoters (AGP). Two hundred and forty Avian broilers were allocated to a 2 × 2 factorial experiment involving two levels of CA (0 or 1000 mg CA/kg feed), and two levels of BCP supplementation (0 or 100 mg/kg feed). The diets and water were offered ad libitum. The growth performance and serum urea nitrogen was significantly increased when CA supplemented (P<0.05), while BCP significantly affects the ammonia concentration of the husbandry environment (P<0.05). These results indicate that CA and BCP combination can effectively improve the performance and husbandry environment.

Effect Of Feeding

A five-week study was conducted to determine the effect of feeding varying levels of S. cerevisiae on carcass and organ characteristics of finishing broilers. One hundred and twenty 4-weeks old broilers of cobb strain were randomly assigned to four treatments (T1 = 0.6 g Saccharomyces cerevisiae (SC) kg–1 diet; T2 = 0.8 g SC kg–1 diet; T3 = 1.0 g SC kg–1 diet and T4 = 0.0 g SC kg–1 diet) with 30 birds per treatment and replicated twice with 15 birds per replicate in a completely randomized design. Feed and water were provided ad libitum to the birds in a deep litter system. In the end, data on growth, carcass and organ indices generated from the study were analyzed using one-way analysis of variance (ANOVA). Results showed no significant difference (p > 0.05) among the treatments in the birds’ growth performance indices. However, significant differences (p < 0.05) were observed in the birds’ values for liver weight, heart weight, shank length and thigh length with birds in T3 recording highest values of 61.30 g, 16.93 g and 12.00 cm for liver weight, heart weight and thigh length, respectively. It was thus concluded that finishing broilers fed 1.0 g of S. cerevisiae had superior carcass and organ characteristics than birds on the control and lower levels of inclusion.

The Cost

The growing concern about the cost of feed ingredients, use of least cost feed formulation and maintenance of a reliable nutritional requirement for broiler birds irrespective of the season is almost compelling to look for alternatives. Thus, this experiment was conducted to evaluate the performance of broiler chickens fed rice milling waste (RMW) as a replacement for maize. Chemical composition of rice milling waste was determined, while eleven experimental diets each were formulated to contain RMW as replacement for maize at 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%. Three hundred (300), 7-day-old chicks were allocated to the 11 dietary treatments each having 3 replicate pens with 10 birds per pen in a Completely Randomized Design (CRD). Feed and water were provided ad libitum for 6 weeks. Growth performance, carcass yield, organ proportions and economics of production were monitored. Data were subjected to ANOVA at P<0.05. The result from the chemical composition showed that rice milling waste has 89.84% dry matter, 10.80% crude protein and 24.09% crude fibre, while the gross energy was 3789 kcal/g, this showed that RMW is suitable as feed ingredient and as well would not hinder absorption and nutrient utilization. The result of the growth performance showed that broiler chickens fed 10% - 40% RMW had greater average daily weight gain (55.33g- 47.97g), reached a greater slaughter and carcass weight (1500g – 1650g) and were more feed efficient than broiler chicken of the other treatments (P<0.05 for each). In addition, from an economical point of view birds fed 10 - 40% were superior to the other treatments where the cost/kg weight gained (N292.21K – N315.96K) were lower than the remaining treatment groups. Thus, the inclusion of RMW in diet of broiler chickens as a replacement for maize improved nutrient utilization and economic value. It can therefore be recommended that RMW can be used to replace maize between 10% -40% in the diets of broiler chickens.     La préoccupation croissante au sujet du coût des ingrédients alimentaires, de l'utilisation de la formulation d'aliments pour animaux les moins coûteux et du maintien d'une exigence nutritionnelle fiable pour les oiseaux de gril, quelle que soit la saison, est presque convaincante pour chercher d'autres solutions. Ainsi, cette expérience a été menée pour évaluer la performance des poulets à griller nourris aux déchets de fraisage du riz (le 'RMW') comme remplacement du maïs. La composition chimique des déchets de fraisage du riz a été déterminée, tandis que onze régimes expérimentaux ont été formulés pour contenir le 'RMW' comme remplacement pour le maïs à 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% et 100%. Trois cents (300), poussins de 7 jours ont été alloués aux 11 traitements diététiques ayant chacun 3 stylos de répétition avec 10 oiseaux par stylo dans un design complètement randomisé (CRD). L'alimentation et l'eau ont été fournies ad libitum pendant 6 semaines. Les performances de croissance, le rendement de la carcasse, les proportions d'organes et l'économie de la production ont été surveillés. Les données ont été soumises à ANOVA (P<0.05) Le résultat de la composition chimique a montré que les déchets de fraisage du riz ont 89,84% de matière sèche, 10,80% de protéines brutes et 24,09% de fibres brutes, tandis que l'énergie brute était de 3789 kcal/g, ce qui a montré que le 'RMW' est approprié comme ingrédient d'alimentation et ainsi n'entraverait pas l'absorption et l'utilisation des nutriments. Le résultat de la performance de croissance a montré que les poulets a griller nourris 10% - 40% RMW avaient un gain de poids quotidien moyen plus élevé (55.33g- 47.97g), ont atteint un plus grand poids d'abattage et de carcasse (1500g - 1650g) et étaient plus économes en aliments pour des animaux que le poulet de gril des autres traitements (P<0.05 pour chacun). En outre, d'un point de vue économique, les oiseaux nourris de 10 à 40 % étaient supérieurs aux autres traitements où le coût/kg de poids gagné (N292.21 K – N315.96 K) était inférieur à celui des autres groupes de traitement. Ainsi, l'inclusion du RMW dans l'alimentation des poulets de poulet a griller comme remplacement du maïs a amélioré l'utilisation des nutriments et la valeur économique. Il peut donc être recommandé que le 'RMW' peut être utilisé pour remplacer le maïs entre 10% -40% dans les régimes des poulets à griller.
