Growth and Carcass Characteristics of Early- and Late-Feathering Broilers Reared Under Different Feeding Regimens

Evaluation of Growth Performance, Carcass Characteristics, Litter Quality and Foot Lesions of Broilers Reared under High Stocking Densities

Two repeated experiments were conducted to investigate the effects of different stocking densities onbroiler performance, carcass characteristics, litter quality and foot lesionsusing 5224 one day-old Ross 308 broilers. In each experiment, a total of 2612 one day-old broilers were allocated in 16 floor pens at densities of 16, 18, 20 and 22 birds/m2 of floor space in an environmentally controll...

Effects of supplementary feeding on growth and carcass characteristics of fat-tailed lambs grazing cereal stubble

Despite a shortage of animal feed in Iran, cereal stubble is often underutilized due to agro-economic reasons. On the other hand, lambs fed with a conventional fattening ration deposit a considerable amount of fat; therefore, this experiment was conducted aimed at better utilization of cereal stubble and reducing the fat content of lamb carcasses. Fat-tailed Mehraban and Ghezel ram lambs were p...

Comparison of continuous and discontinuous feeding regimens on the growth and survival of larval and early juvenile Atlantic sturgeon (Acipenser oxyrhynchus) under hatchery conditions

Carcass and body organ characteristics of broilers supplemented with dietary sodium and sodium salts under a phase feeding system

The effect of sodium and sodium salts on carcass and body organ characteristics of broilers under a four phase feeding program were investigated. A basal diet (0.08% dNa with NaCl) was formulated and one of two sources of dNa (NaHCO3 and Na2SO4) were supplemented to obtain four different percentages of dNa (0.17, 0.26, 0.35, and 0.44%) for each treatment. There was a linear decrease in dressing...

Proximate Composition and Meat Quality of Broilers Reared under Different Production Systems

In this study, the physical-chemical characteristics and proximate composition of the meat of of two strains of broilers (Paraíso Pedrês and Máster gris plumé – Super Pesadão, utilized for semi-intensive rearing) and Cobb strain, utilized in intensive rearing systems) were evaluated. Differences related to strain and sex (males and females) were studied. Cobb broilers were slaughtered at 45 day...
