This study was performed to determine the optimum level of soybean meal diets for two banded sea bream for growth performance, nutrient utilization, body composition and serum biochemistry. Two banded seabream were fed five experimental diets which were formulated replace fish meal by soybean meal at 0, 20, 30, 40 and 50%. Up to 40% of dietary fish meal was successfully replaced with no growth...

Objective: The protein quality of earthworm meal was evaluated and compared to that of soybean meal (SBM) in two experiments using broiler chicks.  Methods: The protein quality of earthworm meal was evaluated and compared to that of soybean meal (SBM) in two experiments using broiler chicks. Results: The results of experiment 1 indicated that there were no significant differences between earthw...

Since 2001 the European Commission banned the use of meat and bone meal and its byproducts in diets for livestock animals (EC directive 999/2001) in order to assure consumer safety on animal products. Consequently, soybean meal became the most utilised protein source in the intensive livestock systems. Moreover, the proteins of this source are low degradable in the rumen and well proportioned t...

The presence of carotenoids in animal tissue reflects their sources along the food chain. Astaxanthin, the main carotenoid used for salmonid pigmentation, is usually included in the feed as a synthetic product. However, other dietary sources of astaxanthin such as shrimp or krill wastes, algae meal or yeasts are also available on the market. Astaxanthin possesses two identical asymmetric atoms ...

Hericium erinaceus (Bull.:Fr) Pers. is a medicinal mushroom that has various health benefits and rich source of bioactive compounds antioxidant activity. In recent years, H. been considered for its many properties widely consumed in Asian countries. Remarkably, the effect cultivation using substrates composed soybean meal by-products on growth, as well enhancement activity, was evaluated. Our r...

Dairy cows utilize feed crude protein (CP; N x 6.25) with much greater efficiency than other ruminant livestock but still excrete about 2-3 times more N in manure than in milk. This contributes to increased costs of milk production and to environmental N pollution. The function of dietary CP is to supply the cow with metabolizable protein (MP) as absorbed amino acids (AA) but any extra dietary ...

BACKGROUND In addition to an increased risk for chronic illnesses, obese individuals suffer from social stigmatization and discrimination, and severely obese people may experience greater risk of impaired psychosocial and physical functioning. Lower health-related quality of life (HRQOL) has been reported among obese persons seeking intensive treatment for their disease. To aid in the treatment...

The objective of this N balance study was to determine the potential for improving the efficiency and rate of dietary N utilization in Holstein steers by feeding an amino acid-balanced mixture of animal by-product protein sources in combination with urea. The Beef NRC 1996 Model Level 2 was used to formulate a corn-based (86:14 concentrate-hay) control diet with soybean meal as the primary N su...
