effect of intermittent mash-pellet feeding programs on broilers performance, ascites susceptibility and economic yield was studied using 480 broilers in six treatments and five replicates of 16 chicks per pen were used in a completely randomized design. treatments including: 1. mash feed, 2. heated-mash feed, 3. mash feed in starter and grower and pellet feed in finisher, 4. mash feed in starte...

The objective of this study was to examine main and interactive effects of nutrient density (ND), feed form (FF; mash, pellet), and lighting program (12L:12D, 20L:4D) on production characteristics and meat yield of broilers raised to 35 d of age. Diets (starter, grower, and finisher) were formulated so that amino acid levels were in proportion to the dietary energy level. Lighting programs were...

The effect of hatch location and diet density on the prevalence of footpad dermatitis and growth performance in broiler chickens was studied. Broilers (Ross 308), incubated at 2 different hatch locations but originating from the same parent stock, were subjected to 2 feeding programs differing in energy content (2,750 vs. 2,950, 2,850 vs. 3,050, 2,900 vs. 3,100, and 2,900 vs. 3,100 kcal/kg for ...

This experiment was conducted to investigate the effect of the form of diets with different levels of protein and energy on broilers performance at the end of the third week. A total of 2800 male broiler chicks were fed with two forms of diet (mash and crumble-pellet), two levels of protein (23% and 21% CP), and two levels of energy (3200 and 3000 Kcal/Kg ME) from 1 to 21 days of age. The bodyw...

The factorial approach has been used to partition the energy requirements into maintenance, growth, and production. The coefficients determined for these purposes can be used to elaborate energy requirement models. These models consider the body weight, weight gain, egg production, and environmental temperature to determine the energy requirements for poultry. Predicting daily energy requiremen...

l-carnitine as a water soluble derivative of lysine has a crucial biological role in lipid metabolism. present experiment was conducted to study the effect of l-carnitine supplementation into broiler and/or breeder diets on broilers' performance, blood related factors, carcass characteristics and immune system. l-carnitine was added to the broiler breeder's diets at levels of 0, and 6...

A research study was conducted at Peshawar to investigate the effect of Habek mint on the hematology, immunity and overall performance of broilers. One hundred and sixty day-old broiler chicks were purchased from a local hatchery and divided into four groups (A, B, C and D; each group representing four replicates with 10 chicks per replicate). Group A, B and C were respectively given Habek mint...

The effects of graded levels of corn distillers dried grains with solubles (DDGS) were investigated as a partial replacement for sources of protein, energy, and other nutrients for broilers when the digestible amino acid balance was maintained. Zero, 8, 16, and 24% DDGS were incorporated into isonutritive diets at the expense of corn, soybean meal, and dl-Met. Poultry oil, l-Lys, and l-Thr addi...
