Effective utilization of available feed resources is the key for economical livestock rearing. Complete feed system is one of the latest developments to exploit the potential of animal feed resources in the best possible way. The complete feed is a quantitative mixture of all dietary ingredients, blended thoroughly to prevent separation and selection, fed as a sole source of nutrients except wa...

This study was conducted to evaluate the effects of diets containing 0, 100, 200 and 300 mg of carotenoid/kg diet from marigold meal on skin pigmentation, growth, feed utilization and survival of goldfish (Carassius auratus), with average initial weight of 1.8 g for a rearing period of 63 days. The pigmentation degree in skin of goldfish increased significantly with increasing inclusion of mari...

Background The objective of the present study was to evaluate the growth performance and feed utilization of African catfish fed a commercial diet and reared in Clarias gariepinus the biofloc system enhanced with probiotic. Methods The treatment was the frequency of probiotic application into the cultured system, namely, 5-day interval, 10-day interval, and 15-day interval for 60 days of experi...

The cost of feed is the most important cost in pig meat production (about 60%), and the energy component represents the greatest proportion. 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. Evaluation of energy content of pig feeds is usually based on their digest...

The consumption of animal by-products has continued to witness tremendous growth over the last decade. This is due to its potential to combat protein malnutrition and food insecurity in many countries. Shortly after slaughter, animal by-products are separated into edible or inedible parts. The edible part accounts for 55% of the production while the remaining part is regarded as inedible by-pro...
