overcrowding of broiler chicks due to lack of space induces harmful effects which act as predisposing factor in the reduction of production and performance in poultry. supplementation of antistressor products can ameliorate adverse effect of various stressors in poultry. an experiment was designed by inducing overcrowding stress and its management by supplementation of polyherbal antistressor, ...

Commercial brown-egg layers have the genetic potential to produce 26.5 kg egg mass per hen housed (405 eggs with 65.5 g average weight) in a prolonged laying period of 16 months, with a feed conversion ratio of 2.1 kg feed per kg egg mass (Lohmann Tierzucht, 2011). Rapid growing broilers reach market weight of 2.1 kg live weight in 5 weeks, with a feed conversion of 1.6 kg feed per kg live weig...

the aim of this study was to investigate the processing methods of sorghum grain and diet formulation on performance and nutrients digestibility in broilers. three hundred and twenty chicks at eight day of age were allotted into eight groups of four replicate with ten chicks per replicate. this research was conducted as completely randomized design arranged in a 2 × 2 × 2 factorial experiment u...

Possible roles of algae (i.e. “green water”) in facilitating Macrobrachium rosenbergii larviculture have been investigated in the present study. Three types of algae were mixted with shrimp larval feed. Algal members were belonging to the family like Cyanophyceae, Chlorophyceae and Charophyceae respectively. Algal mixture was applied with control feed, showed better result in shrimp larval deve...

—To optimize the essential amino acid (EAA) profile for mature striped bass Morone saxatilis, diets with graded levels of three essential amino acids—lysine (Lys), threonine (Thr), and total sulfur amino acids (Tsaa) methionine and cysteine—were fed to 4-year-old striped bass females. The relative concentrations of these EAAs were maintained in ratios similar to those determined from the analys...

the spanish turbot aquaculture sector holds a top position in the international market. thisactivity is mainly developed along the galician coast (nw spain). this article evaluates the environmentalperformance of galician turbot aquaculture according to the life cycle assessment (lca) methodology.previously, on account of the expected relevance of feed for aquaculture, marine aquafeed productio...

the aim of the present study was to assess whether near infrared reflectance spectroscopy (nirs) and regression equations are the practical and accurate approach of nutritional assessment of common feedstuffs. therefore two experiments were conducted to study the effect of amino acid determination methods on broiler performance. in experiment i, two hundred thirty four male ross broiler chicks ...
