AbstractA 3 ✕ 2 factorial experiment was conducted to investigate the interaction between lactofeed 70 (LF70) (860 g/kg whey permeate, 140 g/kg soya-bean meal, Volac International, UK) levels and soya-bean meal inclusion (SBM) (90 and 225 g/kg) from day 0 to day 25 after weaning (starter period) on growth performance and diet digestibility. A common diet was offered from day 25 to day 38. Dietary treatments were established by substituting LF70 for extruded wheat and soya-bean meal for potato protein (PP) and soya protein concentrate (SPC). Digestible energy and amino acids were maintained by adjusting soya oil and synthetic amino acids. A total of 252 pigs (7·7 kg and 28 ± 2 days of age) were allotted randomly to six treatments containing (1) 0 LF70 with 40 g/kg PP and 40 g/kg SPC and 90 g/kg SBM (2) 0 LF70 with 225 g/kg SBM (3) 175 g/kg LF70 with 40 g/kg PP and 40 g/kg SPC and 90 g/kg SBM (4) 175 g/kg LF70 with 225 g/kg SBM (5) 350 g/kg LF70 with 40 g/kg PP, 40 g/kg SPC and 90 g/kg SBM and (6) 350 g/kg LF70 with 225 g/kg SBM. There was an increase in average daily gain (ADG) (0·182 v. 0·292 v. 0·318 kg, s.e. 0·0089; P < 0·001) and food intake (0·413 v. 0·472 v. 0·489 kg, s.e. 0·0139; P < 0·01) and an improvement in food conversion ratio (FCR) (2·31 v. 1·63 v. 1·55 kg, s.e. 0·037; P < 0·001) as the level of LF70 increased during the starter period. From day 25 to day 38, the pigs given the starter diets containing no LF70 had an improved ADG (P < 0·05) and FCR (P < 0·001) compared with the pigs given 175 and 350 g/kg LF70. The pigs offered diets containing 350 g/kg lactofeed had a significantly higher N digestibility (P < 0·05) than the pigs offered diets containing no lactofeed. There was a significant interaction (P < 0·001) between LF70 and SBM in the apparent digestibility of gross energy (GED). Pigs given higher SBM diets had a higher GED at the 350 g/kg LF70 inclusion than pigs given PP + SPC diets. However, there was no difference in GED at the 0 and 175 g/kg LF70 inclusion. In conclusion, the inclusion of LF70 increased ADG, food intake and apparent N digestibility and improved FCR.

Abstract The objective of this study was to determine the effect of increasing dietary synthetic amino acids L-Lysine HCl, L-Threonine, Alimet®, and L-Tryptophan inclusion level at the expense of soybean meal on growth performance during the grow-finish period (46.2 ± 0.55 to 127.4 ± 0.83 kg BW) and carcass characteristics of pigs reared under commercial conditions. The study used a RCBD with 2 dietary treatments: 1). Control: 0.309, 0.029, 0.028, and 0.000 g/kg of synthetic lysine, methionine, threonine, and tryptophan, respectively; 2). High Inclusion: 0.422, 0.069, 0.047, and 0.014 g/kg, respectively. Diets were corn-soybean meal based with DDGS (20.6% for both diets) formulated to be isocaloric and to the same SID amino acid levels but varied in soybean meal inclusion (14.1 and 10.2%, for the Control and High Inclusion, respectively) and crude protein content (17.7 and 16.4%, respectively). A total of 3,520 barrows and gilts were used, housed in single-sex pens of 32 (22 replicates) at a floor space of 0.67 m2/pig. Pigs had ad libitum access to feed and water throughout the study. Pen was the experimental unit and data were analyzed using PROC MIXED of SAS; the model accounted for fixed effect of dietary treatment and the random effect of block. There was no effect of dietary treatment on final live weight, overall ADFI, hot carcass weight, backfat depth, or longissimus muscle depth. However, the High Inclusion treatment had lower overall ADG (P ≤ 0.01) and overall G:F (P ≤ 0.05), but greater (P ≤ 0.01) carcass yield than the Control treatment. These results suggest that increasing the inclusion of synthetic amino acids in corn-soybean and DDGS based diets for growing-finishing pigs to the levels evaluated negatively impacted growth rate and feed efficiency but increased carcass yield.
