Regardless of the phase of growth, lysine is the first limiting amino acid for swine and balancing diets with crystalline L-lysine is a well-established practice around the world. There are two lysine sources available to nutritionists: L-lysine HCl and L-lysine sulfate.
A lot of people will reasonably connect egg size with hen age; older hens lay bigger eggs. This is true, but there are numerous other influencing factors. Egg production management practices can also impact the size of an egg, with body weight and nutrition having the greatest influence.
Over the last couple of decades, resources have been utilized to determine the comparative nutritional efficacy of methionine hydroxy analogue free acid (MHA-FA) to its dry counterpart, DL-methionine (DL-Met). During this time, a multitude of research studies have evaluated sources of methionine and effectively raised DL-Met to be the “gold standard” source for its 100% availability.
Management of nutrition and gut health is essential in achieving clean eggshells. Feed stuff selection in particular is vital. For instance, it is crucial producers are aware of any anti-nutritional factors, toxins or contaminants contained in feed that can lead to nutritional imbalances, intestinal diseases and reduced overall bird health.
Good-quality Distillers' Dried Grains with Solubles (DDGS) are high in energy and amino acid content and free of anti-nutritional factors such as mycotoxins and can support good egg production and egg quality. With inclusion rates of 3 to 5% for pullets and rates of up to 15% for layers, DDGS is widely recognized as an excellent feedstuff.
The key to successful nutrition in poultry is about more than offering nutrients to meet requirements for maximum performance. Effective nutrition embraces a range of issues including raw materials, feed additives and ideal bacterial ecology.
One of the core processes in compound feed production for feed mill operators is pelleting. As well as increasing bulk density it also stabilizes the mixture. This delivers a uniform particle size, which improves storage and handling properties and lowers transportation costs.
