With global warming, heat stress will become more and more serious. This paper reviewed the effects of heat stress on metabolism of proteins, glucose, fat and energy in skeletal muscle and related mechanisms so as to provide theoretical guidance for alleviating heat stress and improving production performance of animal suffering from heat stress.展开更多

The menace to human health and environment has occurred since too much antibiotics have been used as growth-promoting additives in long term in chicken industry. Therefore, research on replacement of antibiotics by Chinese herb medicines as additives for chicken growth is underway. This paper summarized some research results in the topic briefly to provide information for researchers and readers.展开更多
