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

Abstract

Objetive. Two experiments were designed to evaluate the effect of peach palm meal and synthetic lysine on blood lipids of growing and finishing pigs. Materials and methods. In experiment 1, 72 barrows of 30 ± 0.5 kg were randomly allotted into a 2x3 factorial design: being the main factors levels of synthetic lysine (0 and 2.70 g/kg) and levels of peach palm meal (0, 160 and 320 g/kg). In experiment 2, 16 finishing pigs of 67.25 ± 1.17 kg were used and allotted in a 2x2 factorial design arrangement of treatments: with two levels of synthetic lysine (0 and 2.70 g/kg) and two levels of peach palm meal (0 and 175 g/kg). Serum triglycerides, total cholesterol and fatty acid profile were determined. Results. In experiment 1, growing pigs fed with 160 and 320 g/kg of peach palm showed lower (p

Abstract

Objetivo. Evaluar el efecto de la harina de pijiguao y lisina sintética sobre los lípidos sanguíneos de cerdos en crecimiento y engorde. Materiales y métodos. El estudio se realizó en dos etapas. En la primera etapa se utilizaron 72 cerdos castrados en crecimientode 30 ± 0.5 kg, en un arreglo factorial 2x3: dos niveles de lisina sintética (0 y 2.70 g/kg)y tres niveles de harina de pijiguao (0, 160 y 320 g/kg). En la segunda etapa se utilizaron 16 cerdos en engorde de 67.25 ± 1.17 kg, en un arreglo factorial 2x2: dos niveles de lisinasintética (0 y 2.70 g/kg) y dos niveles de pijiguao (0 y 175 g/kg). Se determinaron las concentraciones séricas de triacilgliceroles, colesterol total y ácidos grasos. Resultados. Los cerdos en crecimiento que consumieron pijiguao presentaron menores (p
