Lysine requirement for maintenance in growing pigs
Probably due to methodological problems the knowledge about the AA requirement for maintenance in pigs is rather scarce. In the present study an alternative experimental approach was applied and its underlying hypothesis was tested, whether protein retention decreases with body weight (BW), when daily lysine intake remains constant and acts as the limiting factor for protein retention, and whet...
متن کاملThe Optimal Dietary Threonine to Lysine Ratio for Growing Pigs
The growth of 64 pigs was monitored over grower and finisher periods of 26-58 and 58-96 kg respectively, to see if the optimum dietary ratio of threonine to lysine (T/L) under ad Zibitum feeding was higher than the generally accepted ratio of 0.6. Five basal (Bl-B5) diets were used to establish the pig’s response to lysine (in the range 6.0 to 11.24 and 5.59 to 10.5 g kg-1 for grower and finish...
متن کاملEstimate of the variability of the lysine requirement of growing pigs using the indicator amino acid oxidation technique.
Although AA requirements for the mean in a population of growing pigs are well established, there are no direct estimates of their variability within the population. The indicator AA oxidation method allows repeated measurements in a short period of time so that the AA requirement can be determined for individual pigs. The objective was to determine the Lys requirement in individual pigs to der...
متن کاملMaintenance requirement and deposition efficiency of lysine in pigs
The objective of this work was to determine the maintenance requirement and the deposition efficiency of lysine in growing pigs. It was used the incomplete changeover experimental design, with replicates over time. Twelve castrated pigs with average body weight (BW) of 52±2 kg were kept in metabolism crates with a controlled temperature of 22°C. The diets were formulated to supply 30, 50, 60, a...
متن کاملDigestible lysine requirement of starter and grower pigs.
Three experiments were conducted to determine the digestible lysine requirement of starter (6 kg BW initially) and of grower (21 kg BW initially) pigs. Experiment 1 used 294 starter pigs and lasted 28 d; Exp. 2 used 182 grower pigs and lasted 35 d. Protein and total lysine contents of the basal corn-peanut meal diets were 20 and .8% for Exp. 1 and 16 and .54% for Exp. 2. Basal diets were fortif...
