| Popis: | The study was conducted to investigate the effect of supplementing a simple corn-soybean meal (SBM) diet with multi-enzyme complexes, essential oils, and benzoic acid on growth performance, serum metabolite profile, serum cytokines, and intestinal microbiota in weanling pigs. Forty-eight gilts and 48 castrated males weaned at 3 to 4 wk of age (initial body weight, 7.96 ± 0.89 kg) were randomly assigned to 4 dietary treatments with 3 gilt and 3 castrated male pens per treatment and 4 gilts or 4 castrated males per pen. A complex diet containing palatable and digestible ingredients was formulated (1.30 g standardized ileal digestible Lys/kg) to serve as the positive control (POS) diet. A simple corn-SBM, negative control (NEG) diet was formulated to be isolysinic to the POS diet, and the NEG diet was supplemented with multi-enzyme complexes (ENZ) or multi-enzyme complexes, essential oils, and benzoic acid (ALL). All diets were formulated to meet or exceed the 2012 NRC nutrient requirements of pigs weighing 7 to 25 kg. During the fourth week, blood samples were collected to determine serum metabolite profile and cytokines, and fecal samples were collected for the enumeration of bacteria. Pigs had ad libitum access to feed and water throughout the 4-wk study. From d 0 to 7 and 7 to 14, pigs fed the POS diet had greater feed and Lys intake (P |
