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...

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, ...

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 ...

The North American pork production industry is heavily dependent on relatively few feed ingredients, including the cereal grains (corn, wheat, and barley), oilseed meals (soybean meal) and industry co-products (DDGS). As such, factors that impact the quality of these feed ingredients can pose serious challenges relative to the formulation of pig diets. One such factor that impacts the quality o...

The efficacy of top-dress antiinflammatory drugs ultimately depends on a patient's willingness to consume treated feed. The current study compares the palatability of two phenylbutazone top-dress formulations (Equipalazone Powder, Dechra Pharmaceuticals, and Pro-Dynam, VetXX, Ltd.) and a suxibuzone top-dress formulation (Danilon Equidos, Janssen Animal Health). Results of a three-period, crosso...

The cost of feed is the most important cost of pig meat production (~60%) and the energy component represents the greatest proportion of the feed. Therefore, it is important to estimate precisely the energy value of feeds, either for least-cost formulation purposes or for adapting feed supply to energy requirements of animals. In addition, energy supply has an important impact on performance of...
