The purpose of this study was to determine if the efficiency of energy retention in pregnant cows was dependent on the time during the pregnancy that feed was offered. Our hypothesis was that restricting feed intake during the second trimester of gestation and providing the saved feed during the third trimester was less energetically efficient than providing the feed during the second trimester...

Healthy and sustainable diets should be put at the center of food systems planning if we want to feed growing population while making a use natural resources protect biodiversity.

Algae are at the base of the aquatic food chain, producing the food resources that fish are adapted to consume. Previous studies have proven that the inclusion of small amounts (<10% of the diet) of algae in fish feed (aquafeed) resulted in positive effects in growth performance and feed utilisation efficiency. Marine algae have also been shown to possess functional activities, helping in the m...

Fish wastes management has become a global problem from the last years. Dispose of seafood wastes cause environmental pollution. To overcome this issue these unwanted seafood products are used for the formation of animal feed and aquaculture feed. These unwanted products include small fish and those parts of fish which are not used as human food. These unwanted parts include viscera, head, fins...

Modern animal breeding programs are largely based on biotechnological procedures, including AI and embryo transfer technology. Recent breakthroughs in reproductive technologies, such as somatic cell nuclear transfer and in vitro embryo production, and their combination with the emerging molecular genetic tools, will further advance progress and provide new opportunities for livestock breeding. ...
