The standardized ileal digestible valine-to-lysine requirement ratio is at least seventy percent in postweaned piglets.
To reduce the impact of animal production on the environment, the CP content of the diet can be reduced by limiting the excess supply of AA. Improving the balance between AA relative to the requirement of the animal implies that we need to have accurate knowledge of the requirement of individual AA. The purpose of this study was to determine the Val requirement in postweaned piglets (12 to 25 k...
متن کاملLysine 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...

and ADFI at week 4 (P = 0.02). During phase 2 (week 3 to 4), greater ADG (P = 0.05) and ADFI (P = 0.004) were observed in pigs consuming a diet containing DDGS (Treatments B and D) compared to pigs that did not receive DDGS in phase 1 (Treatments A and C); however, G:F ratio was not affected by DDGS. There was a lactose effect on ADG in week 3 (P = 0.05) and a trend of lactose effect on ADG dur...
متن کاملEstimation of the tryptophan requirement in piglets by meta-analysis.
There is no consensus concerning the Trp requirement for piglets expressed relative to Lys on a standardized ileal digestible basis (SID Trp : Lys). A meta-analysis was performed to estimate the SID Trp : Lys ratio that maximizes performance of weaned piglets between 7 and 25 kg of BW. A database comprising 130 experiments on the Trp requirement in piglets was established. The nutritional value...
متن کاملDietary selection for lysine by piglets at differing feeding regimen
Article history: Received 14 August 2007 Revised 10 September 2008 Accepted 10 September 2008 The aim of the present study was to investigate preferences of piglets for diets varying in lysine (Lys) concentration andwhether those preferences are influenced by changing position of diets on offer in feeders. For this purpose, a feeding trial was carried out over a period of 5 weeks. Piglets (equa...
