Standardized ileal digestible (SID) isoleucine requirement of barrows (15- to 30- kg) fed low crude protein diets

Abstract: This study aimed to determine the SID isoleucine (Ile) requirement of starting barrows fed low crude protein. Two experiments were carried out. Experiment 1: Ten crossbred barrows were used in order to determine the SID AA of the basal diet (treatment with the lowest SID Ile level used in the growth performance experiment), averaging 15.00 ± 0.27 kg of initial weight, individually housed in metabolic cages and allotted in a complete randomized design, with two treatments, five replicates and one animal per exp… Show more

“…Barrows from 15 to 30 kg, fed diets with a low crude protein content (14%), showed to have maximal daily gain and protein deposition at a SID isoleucine to lysine ratio of 58% (Lazzeri et al, 2017). This ratio is higher than the recommended NRC (2012) value, but in line with several European recommendations (Table 1).…”
