this experiment was conducted using 216 male chicken (ross 308) to evaluate the effects of organic selenium and sodium bicarbonate supplementation on blood parameters, growth performance and carcass characteristics in heat stress condition. birds were reared under same condition and fed with similar diets till 28 d of age. at 28 days of old, broiler with similar weight were regrouped within die...

An experiment was conducted to evaluate the effects of a restriction to home-grown feedstuffs and abstinence from supplementation with synthetic amino acids (AA), as ideal objectives in organic pig production according to the IFOAM standards, on growth performance and carcass characteristics. One hundred individually housed pigs were allocated to four dietary treatments and fed from growing thr...

in the past decade, a global demand for products from organic agriculture has increased rapidly. milk quality is of major interest for all parties. therefore, the objective of this study was to compare cow performance and product quality in conventional and organic system. twenty holstein dairy cows were allotted to one of 2 diet groups, which including: a conventional diet (con), and an organi...

The goal of this article was to compare the effects of a prolonged use of organic and transgenic soy on the lipid profile and ovary and uterus morphology. Wistar rats were fed three different diets from weaning until sacrifice at 15 months of age. The three diets were: casein-based diet control group (CG), organic soy-based diet group (OSG), or transgenic soy-based diet group (GMSG). There were...

The objective of this study was to investigate the effects of feeding electron irradiated flaxseed (FS) on performance, carcass characteristics, blood parameters, digesta viscosity, and nutrient digestibility in broiler chickens. In a 2 × 2 factorial arrangement, 320 day-old broiler chicks were randomly assigned to one of five experimental diets, each with four replicates containing 16 chicks e...

In recent years, a growing interest from consumers to know the origins and contents of foods has put alternative choices, such as organic foods and dietary changes, on the agenda. Dietary choices are important to address, as many studies find that activities related to food production account for nearly 20–30% of anthropogenic greenhouse gas (GHG) emissions. Nonetheless, while GHG emissions are...

Organic acids have been supplemented to weanling pig diets in an attempt to improve postweaning lag. Organic acids have proved beneficial in improving average daily gain (ADG) and increasing nutrient digestibility (Falkowski and Aherne, 1984; Edmonds et al., 1985; Geisting and Easter, 1985). There has also been interest in acidifying grower pig diets in an attempt to increase ADG and improve fe...

Selenium (Se) is an essential element for animals, including fish. Due to changes in feed composition for Atlantic salmon (Salmo salar), it may be necessary to supplement feeds with Se. In the present work, the transfer of Se and Se species from feed to muscle of Atlantic salmon fed Se supplemented diets was studied. Salmon were fed basal fish feed (0.35 mg Se/kg and 0.89 mg Se/kg feed), or fee...

Rickets has been produced experimentally in rabbits by the administration of diets deficient in the antirachitic organic factor and phosphorus but with a high calcium content. Cod liver oil added to these rickets-producing diets prevented the development of rickets in rabbits.
