dc.description.abstractEffects of Dietary Energy and Amino Acid Levels on Growth Performance, Physiological Responses and Reproductive Performance in Swine



The objectives of this research described were 1) to evaluate the effect of dietary energy and amino acid levels on growth performance, blood profiles, meat quality and economic analysis in grower - finisher pigs, 2) to determine the effect of dietary amino acid levels on body changes, reproductive performance, blood profiles and milk composition in gestating to lactating sows, and 3) to investigate the effect of dietary valine:lysine ratios on body changes, reproductive performance, blood profiles and milk composition in lactating sows.



Experiment I. Effect of Dietary Energy and Amino Acid Levels on Growth Performance, Blood Profiles, Meat Quality and Economic Analysis in Grower - finisher Pigs



This experiment was conducted to evaluate the effect of dietary energy and amino acid levels on growth performance, blood profiles, meat quality and economic analysis in grower - finisher pigs. A total of 180 cross-bred pigs ([Yorkshire × Landrace] × Duroc) with an initial mean body weight of 29.5 ± 4.04 kg were allotted to one of six treatments based on 2 × 3 factorial arrangement with 3 replicates. The first factor is two levels of metabolizable energy (ME) and the second factor is three different levels of amino acid (AA), and treatments were 1) LL: 3,200 kcal of ME/kg, NRC (1998) AA requirement		-
