With the complexity and amount of information in a wide variety of comparative performance reports in poultry production, making a decision is difficult. This problem is overcomed only when all data can be put into a common unit. For this purpose, five different decision making analysis approaches including  Maximin, Equally likely, Weighted average, Ordered weighted averages and Technique for ...

The present study was conducted to investigate whether dietary essential oils could affect growth performance, relative organ weights, cecal microflora, immune responses and blood profiles of broiler chickens fed on diets containing different nutrient densities. A total of eight hundred-forty 1-d-old male broiler chicks were randomly allotted into twenty-eight pens (7 pens per treatment, 30 chi...

Chick embryo development is associated with an accumulation of polyunsaturated fatty acids in lipid tissues making them susceptible to lipid peroxidation. It has been accepted that canthaxanthin has high antioxidant capacity. Research findings have repeatedly indicated that feeding 25(OH)D3 (25-hydroxycholecalciferol), to poultry breeders, broilers and layers increased performance and health. T...

Availability of nucleotides may limit performance in fast growing animals. An experiment was conducted to determine the efficacy of a nucleotide preparation (Nucleoforce Poultry) in broiler chickens. Nine hundred and sixty day-old broiler chickens were allocated into 24 pens, and assigned one of 3 treatments: 0, 500 and 1000 mg of the nucleotide preparation/kg feed. Feeds were based on wheat, b...

A nonlinear programming optimization model was developed to maximize margin over feed cost in broiler feed formulation and is described in this paper. The model identifies the optimal feed mix that maximizes profit margin. Optimum metabolizable energy level and performance were found by using Excel Solver nonlinear programming. Data from an energy density study with broilers were fitted to quad...

A study on the effect of probiotic supplementation on broiler peiftmnance was carried out with 600 one day-old Avian broiler chicks. The duration of study was 35 da)lS and a commercially prepared lactobacillus culture was given to the treated birds via drinking water thmughout the 35 days. The results showed that the live weight of the I,·ealed bird was significantly (P<0.05) improved al 21, 28...

Phytase supplementation in broiler diets is a common practice to improve phosphorus (P) availability and to reduce P loss by excretion. An enhanced P availability, and its concomitant supplementation with calcium (Ca), can affect the structure of the microbial community in the digestive tract of broiler chickens. Here, we aim to distinguish the effects of mineral P, Ca, and phytase on the compo...
