Effects of Using Canola Meal as a Protein Source in Broiler Diets
… were conducted to evaluate the response of broilers fed canola meal. Experiment 1 assessed performance and carcass yields when broilers were fed various combinations of canola and soybean meal in nutritionally balanced diets based on digestible amino acid values. The results suggested that …

Quality of South African soybean meal as a factor affecting the efficacy of exogenous protease in broiler diets
… of exogenous protease in soybean-maize based diets, however, is unpredictable and cost- effective inclusion is not always realised. Matrices have to be adjusted continually to accommodate the differences in nutritional composition. Studies on the effects of exogenous protease on ileal amino …

Supplementation of chelated Zn Cu and Mn in broiler diets to improve performance skin integrity and the incidence and severity of footpad dermatitis
… chelates of Cu, Mn and Zn was investigated on broiler performance, carcass characteristics, skin and intestinal integrity and the prevalence of foot pad dermatitis. Two 35-day grow out trials were conducted in an environmentally controlled broiler facility. The purpose of the first trial was to …

Effects of pelleting millet-based diets on the performance of broiler chickens
… production performance and cost efficiency of broilers. The experimental design used in this study was a Completely Randomized Design with a 2 x 3 factorial arrangement of treatments (i.e. two processing methods (grinding and pelleting) and three replacement levels (50%, 75% and 100%). A …

Responsiveness of Cobb MV × 700 Broilers to Dietary Amino Acid and Energy Density
<p>As new broiler crosses are introduced to the industry, it is of paramount importance to understand their nutritional digressions from previous and other modern broilers. In particular, amino acids (AA) and dietary energy have been identified as key drivers of live performance and carcass …

The feeding value of Kenyan sorghum, sunflower seed cake and sesame seed cake for poultry
… seedcake (SSC) as feed ingredients in poultry diets was evaluated at the University of Nairobi, Kenya. A survey of Kenyan sorghum revealed a large variation in the composition of the grains grown. Local sorghum varieties tended to have very high tannin content (up to 13.8% of dry matter) and …

Effect of feeding calcium propionate on carcass composition, and productive performance of male broilers
Male broilers were fed ad libitum a control diet and diets with 1.5% and 2.7% calcium propionate (CaP). Broiler diets were supplemented with CaP for the first 2,4,6, or 8-week intervals. After being fed CaP for the previous mentioned times the broilers received a control diet for the remainder of …

Reducing Dietary Crude Protein: Characterization of Branched-Chain Amino Acid Antagonism in Modern Broiler Chickens
<p>Reducing the crude protein content of broiler diets while maintaining performance has been a primary research area in nutrition. During the late 20th century, the bulk of this research has involved supplementing broiler diets with feed-grade amino acids and proving the economic benefits of their …

Response of Broiler Chickens to Variation in Dietary Nutrient Content
… and their effect on improving efficiency of broilers.</p> <p>The first research project compared the efficacy of two commercially available protease enzymes; Ronozyme ProAct (DSM, Parsippany, NJ) and Cibenza DP-100 (Novus International, St. Charles, MO). Both are broad spectrum proteases that …

Evaluation of Particle Size Differences, Calcium Sources, and Phytases on Ph and Calcium and Phosphorus Solubility in an in Vitro Simulation of Broiler Digestion
Broiler nutrition can be affected by many different factors, and diets can be made up of a wide variety of components. Feed enzymes, different Ca sources, and various ingredient particle sizes all contribute to broiler nutritional status and need to be investigated to determine their full effects …

Evaluation of lysine and metabolizable energy in diets for broilers
… and standardized ileal digestible lysine in broiler diets, focusing on performance and body composition. Two chapters were created based on the results of the trials. In the first chapter, a study was conducted to evaluate the optimal levels of metabolizable energy and standardized ileal …

Quantification and alleviation of the antinutritional effects of phytate on poultry
… meat-type poultry cannot be met by plant-based diets because approximately two thirds of total phosphorus in cereals and leguminous feed materials is in the unavailable form of phytate (inositol hexaphosphate or phytic acid). Phosphorus supplements are expensive and over supplementation can …

Distillers Dried Grains with Solubles: Determination of Metabolizable Energy Values Using Regression-Based Assays and their Correlation with Chemical Composition
… values and limited its potential to use in broiler diets. Therefore, two experiments were conducted to characterize the content of nitrogen-corrected ME (MEn) in 11 DDGS sources obtained from various ethanol plants using a regression-based broiler assay and to attempt to develop equations to …

Effects of sprouted cowpea (vigna unguiculata) dietary inclusion with ronozyme ® ProAct supplementation on broiler performance
… of maize-sprouted cowpea (Vigna unguiculata) diets when fed with supplementary exogenous enzymes on the growth (live weight, live weight gain, feed conversion ratio) and carcass parameters of Ross-308 broilers. Cowpeas were screened for viable seed and sterilised by 30-minute immersion in 2% …

Production and health responses of laying hens and growing broilers to dietary omega-3 fatty acid supplementation
… This has led producers to supplement poultry diets to create enriched eggs and meats and satisfy consumer demand. Thus far, omega-3 fatty acid research has primarily focused on creating value-added foods for the consumer with little attention paid to the effects of supplementation on the …
