Material and Methods: Semen samples were collected by five rams. We assessed different four long-term liquid ...

Introduction and Objective: Antibiotics reduce the microbial population of the gastrointestinal tract, increase the available nutrients, and improve the feed conversion ratio (FCR) and body weight gain (BWG) of broilers. Due to the persistence of antibiotics in manufactured products and their...

Introduction and Objective: The use of antibiotics in poultry nutrition, in addition to their importance in preventing diseases, causes an increase in congenital anomalies, chronic diseases, increased microbial resistance and hundreds of other small and large complications, which is attributed to...

Introduction and Objective: In recent years, application of natural and safe feed additives such as herbs and herbal products has been increased, due to their beneficial concequences on health and thereby animal production. One of the natural important compounds present in plants, is phenolic...

Introduction and Objective: Today, the poultry industry tends to increase production per unit area, at the same time, the increase in flock density is faced with management and health restrictions and obstacles. Consuming medicinal plants can be an effective nutritional solution to overcome the...

Introduction and Objective: Crude protein is one of the most expensive components of feed and nutrients needed by animals. One of the ways to optimally use crude protein is to oscillating the level of crude protein in the diet and feeding it intermittently at intervals of one to several days. This...

Introduction and Objective: In Suckling calves, due to the low development of rumen, the digestibility of food may decrease, so the energy of the diet can be increased by adding fat sources. The present experiment was conducted to investigate the effect of omega-3 and omega- 6 fatty acids on feed...

Introduction and Objective: High concentrated diets are rapidly degraded in the rumen and lower ruminal pH by rapid and high lactic acid production. The use of chemical or biological buffers improves digestion and fermentation conditions in a high concentrate diet. The aim of this study was to...
