Evaluation of Digestible lysine levels in diets with high energy density for finishing pigs

Journal Title: Revista MVZ Cordoba - Year 2015, Vol 20, Issue 2

Abstract

Objective. To evaluate the effects of different levels of digestible lysine in diets with high energy density on productive performance and carcass characteristics of finishing pigs. Materials and Methods. Seventy crossbred barrows (initial body weight of 83.36 kg) were used and allotted in a randomized block design with five treatments, seven replications and two pigs per experimental unit. Pigs were fed ad libitum with diets containing 3.5 kcal/kg of ME and five levels of digestible lysine (0.46, 0.52, 0.58, 0.64 and 0.70%) during four weeks. Final live weight (FLW), daily feed intake (DFI), daily weight gain (DWG), feed conversion (FC), daily lysine intake (DLI), and the amount of lysine per body weight gain (DLI/DWG), were evaluated. At the end of the experiment, blood samples were taken from each pig to determine urea nitrogen concentration (UN) in serum and slaughtered to evaluate quantitative and qualitative carcass characteristics. Results. The FLW increased linearly (p<0.05).There were no differences among treatments for DFI, DWG, FC, carcass characteristics and UN. The DLI and DLI/DWG varied significantly (p<0.001) and increased linearly (p<0.001) with each lysine level. Pigs that consumed the limiting diet in lysine (0.46%) showed less DLI and DLI/DWG (p<0.001) than pigs fed the other diets. Conclusions. The amount of DLI/DWG increased with the evaluated levels of digestible lysine in diets with high energy density, without effects on productive performance and carcass characteristics of finishing pigs.
