Impact of somatotropins on nutrient requirements in domestic animals

Article Abstract:

Growing monogastric and ruminant domestic animals exhibit increased nitrogen retention and improved body composition with the administration of somatotropin. Somatotropin enhances the lean to fat ratio and improves feed conversion ratio in pigs. On the other hand, physiological effects on growing ruminants are variable. Somatotropin increases the basal metabolic energy requirement in swines and ruminants. It also enhances protein accretion which promotes growth. This indicates that there is a need for a substantial increase in the nutrient requirement of somatotropin-treated animals.

Utility and importance of gene knockout animals for nutritional and metabolic research

Article Abstract:

The gene knockout method is one of the molecular biology techniques used to study the role of genes in health and diseases. Mice are the most common type of laboratory animal used in the gene knockout technology. Gene knockout mice can be used to model human diseases and then to study the effects of potential cures, including pharmacological and genetic therapy methods. The can also be used to explore physiological function of specific genes.

Cupric oxide should not be used as a copper supplement for either animals or humans

Article Abstract:

Vitamin manufacturers should stop using cupric oxide in vitamin pills. Cupric oxide has been used because it takes up less space so more can be included in the pill. However, animal studies have clearly shown that this form of copper is not absorbed by the intestinal tract.
