PERFORMANCE AND CARCASS CHARACTERISTICS OF SWINE AT 50 KG FED DIETS WITH DIFFERENT ENERGY LEVELS AND REDUCED LEVELS OF CRUDE PROTEIN

Three experiments were carried out to evaluate the levels of digestible valine in diets with reduced crude protein on the performance, carcass yield and muscle fiber diameter of

Feed conversion ratio decreased with increasing levels of dietary protein and energy in the diets.. A significant interaction between crude protein and gross energy was observed

Table 2 – Daily lysine intake and metabolizable energy intake and efficiency of lysine utilization for pigs from 10 to 20 kg receiving diets with different crude protein and

The level of 1.03% true digestible lysine should be kept on diets with 3230 kcal / kg metabolizable energy and reduced crude protein for growing pigs.. The level of protein in

Therefore, the objective of this work was to evaluate the effect of diets with reduced levels of crude protein, available phosphorus, and calcium, supplemented with phytase and

Thus, the objective of this work was to evaluate the effect of diets elaborated with reduced levels of crude protein and phosphorus, supplemented with phytase and

The use of cottonseed meal with the addition of enzymes in diets for growing pigs has no effect on the digestibility of dry matter, gross energy and crude protein, but improved

Nile tilapia grows suitably with diets based on soybean meal and corn and it is recommended to use 28.3% of digestible protein (31.6% of crude protein) for Nile tilapia between
