| To analyze the effect of conjugated linoleic acid (CLA) on the meat of pigs (0,1%) and three crude protein (CP) levels (nursery: 20.5, 16.0, 14.5%; growing: 16, 14.5, 11.5%; and finishing: 14.0, 12.5, 11% CP), studies were conducted with 36 hybrid (Yorkshire×Landrace×Duroc) barrows (17.3-83.5 kg), which were individually penned and allotted in a completely randomized design in a factorial (2×3) arrangement for 84 d. The analysis by phases indicated that CP level affected some variables. Average daily gain, average daily feed intake, fat free lean gain, backfat thickness, longissimus muscle area and final body weight were reduced (P≤0.05) feeding the lowest CP diet in nursery and growing pigs. Plasma urea nitrogen concentration was also lower (P≤0.05) in... |

| ABSTRACT An experiment was carried out to evaluate the effect of an herbal choline feed plant additive on the productive parameters and blood metabolites of finishing lambs. Forty male Hampshire × Suffolk lambs (initial body weight of 30.36±3.75 kg) were assigned according to a completely randomized design. Treatments consisted of dietary inclusion of the herbal additive BioCholine at 0, 3, 6, and 9 g/kg dry matter for 56 days. A linear response for herbal choline dose was observed for daily gain, final body weight, feed conversion, blood glucose, and blood phosphatidylcholine as herbal choline level was increased in the diet. Total protein, globulins, and low-density lipoproteins showed a quadratic effect, and there were no effects on intake, Longissimus... |

| La proteína cruda (PC) puede reducirse cuatro unidades porcentuales cuando se utiliza maíz-pasta de soya y aminoácidos (AA) para cerdos en crecimiento. Con sorgo no se han obtenido resultados concluyentes. Por ello se realizaron dos experimentos para determinar el porcentaje mínimo de PC en dietas sorgo-pasta de soya adicionadas con AA, con base en la concentración de urea en plasma de cerdos en crecimiento, y su respuesta productiva. En el Experimento 1, el porcentaje de PC en los tratamientos fue: T1) testigo, 16.0; T2) 14.5; T3) 13.0; y T4) 11.5. Se utilizaron ocho cerdas en un diseño cruzado (cross-over), con cuatro periodos de siete días. El último día de cada periodo se obtuvo sangre para determinar la concentración de urea. Se utilizaron varios... |
