DESCRIPTION OF PROBLEM Creatine is a necessary component in energy metabolism, supplying phosphate groups to adenosine diphosphate and recycling them to adenosine triphosphate (ATP) that can be used for maintenance and growth. This creatine-ATP recycling system does not occur in all cells, only in those where there is great variability in energy demand, including muscle cells [1]. Creatine is espe ...

The current global crises pose several different challenges to nutritionists all over the world. Many feed components are increasingly scarce. Due to the manifold recent interferences, this shortage unfortunately affects both, raw components such as wheat, corn or even soybean and sunflower meal as well as synthetic nutrients and additives. This results in enormous economic pressure on feed formul ...

INTRODUCTIONGenetic selection in poultry has progressed continuously since the early 1960s, resulting in faster growth rates and higher meat production (Havenstein et al., 2003a,b). Over the past 60 years, body weight gain has increased fourfold from 1957 to 2005 with a simultaneous 50% reduction in feed conversion ratio and 79% higher Pectoralis major yield in males and 85% in females (Zuidh ...

What if we can enrich the embryo already with a quickly available energy source to better secure hatching and the first days in the life? This is possible by feeding the broiler breeder hen with a source of creatine. Creatine might ring a bell to many, as taking creatine as a supplement is very popular among athletes to gain muscle, enhance strength and improve exercise performance. Creatine ...

IntroductionIn late years, genetic studies on broiler chickens for selection of traits such as high growth rate and larger size of the body shows there is a negative correlation between reproductive traits and increasing yield. So that's in the roosters, physiological disorders like decreased libido, decreased mating numbers and reduced sperm production have increased (Dawkins and Layton, 2012 ...

INTRODUCTION Disease control, high production, product quality, and reasonable production costs have been the recent main goals of the poultry industry. Hence, meeting per capita consumption and welfare to humans necessitates continuous efficient and goal-oriented healthcare to control disease spread and decrease the application of antibiotics (1). These endeavors will include the launch of progra ...

Birds are omnivorous species, they are evolutionarily designed to consu­me products from plant and animal origin. However, for several reasons, poultry nutrition is shifting more and more to a vegetable diet. This shift has resulted in losing some im­portant benefits of animal products, including creatine, an essential com-pound found in meat but not in plants.A feed ingredient survey cond ...
