“…1 Introduction Large variation in performance of weaned piglets and growing-finishing pigs (GF) exists between commercial pig farms (Agrovision, 2017). The health status of pigs is one of the major factors contributing to this large variation in pig performance (Van der Peet-Schwering et al, 2019). Variation in health status exists between farms but also amongst individual pigs within farms, as e.g.…”

“…(2020) performed a study in GF pigs to evaluate the effects of an increased energy and EAA contents in the diet, related to the assumed increased amino acid and energy requirements in immune stimulated pigs (Van der Peet-Schwering et al, 2019), on the growth performance of GF pigs. The diets were evaluated in pigs kept under a low or high sanitary status regime assumed to create a contrast in degree of immune system activation in the pigs.…”

“…Therefore, we performed a study to evaluate the effects of increased levels of dietary energy and essential AA (via additional supplementation of free AA and increase of dietary energy density) on the growth performance of weaned piglets under LSC, in which the immune system of the pigs was supposed to be activated, or under HSC resulting in an assumed lower state of activation of the immune system. The contrast in dietary AA level and profile and energy level of the diets was based on model calculations as described in the desk study "Amino acid requirements in relation to health in growing and finishing pigs" (Van der Peet-Schwering et al, 2019). As sanitary, environmental and management conditions vary largely among farms the research was carried at two experimental farms, allowing to evaluate differences in responses to diet modification among farms.…”

“…Via the present study, the model calculations as described by Van der Peet-Schwering et al (2019) can be validated for weaned piglets and knowledge is developed which will allow the pig production sector and the feed industry to more precisely match nutrient composition of the diet and feeding strategy with the nutritional requirements of pigs under a variety of sanitary and health conditions as encountered in practice. Material and methods…”

“…The control weaner diet and the control starter diet were practice-based diets and met the nutritional requirements (CVB, 2020). The levels of supplementation of EAA and energy in the experimental diets were based on the use of a calculation model as described by van der Peet-Schwering et al (2019) in the report entitled "Amino acid requirements in relation to health status in growing and finishing pigs".…”

Highly intensified rearing conditions and precarious sanitary management predispose pigs to immune system activation, altered amino acid (AA) metabolism, and decreased growth performance. Thus, the main objective of this study was to evaluate the effects of increased dietary tryptophan (Trp), threonine (Thr), and methionine + cysteine (Met + Cys) supplementation on performance, body composition, metabolism, and immune responses of group-housed growing pigs under challenging sanitary conditions. A hundred and twenty pigs (25.4 ± 3.7 kg) were randomly assigned to a 2 × 2 factorial arrangement, consisting of two sanitary conditions (SC, good (GOOD) or salmonella-challenge and poor housing condition (ST + POOR)) and two diets (D, control (CN) or supplemented with AA (Trp, Thr, and Met + Cys:Lys ratios 20 % higher than those of the CN diet (AA+)). Pigs were followed during the growing phase (25 to 50 kg) and the trial lasted 28 days. The ST + POOR SC pigs were challenged with Salmonella Typhimurium and raised in a poor housing condition. The ST + POOR SC increased rectal temperature, fecal score, serum haptoglobin, and urea concentration (P < 0.05) and decreased serum albumin concentration (P < 0.05) compared with GOOD SC. Body weight, average daily feed intake, average daily gain (ADG), feed efficiency (G:F), and protein deposition (PD) were greater in GOOD SC than in ST + POOR SC (P < 0.01). However, pigs housed in ST + POOR SC fed with AA+ diet had lower body temperature (P < 0.05), increased ADG (P < 0.05) and nitrogen efficiency (P < 0.05), and a tendency for improved PD and G:F (P < 0.10) compared with CN diet fed pigs. Regardless of the SC, pigs fed AA+ diet had lower serum albumin (P < 0.05) and tended to decrease serum urea levels (P < 0.10) compared with CN diet. The results of this study suggest that the ratio of Trp, Thr, and Met + Cys to Lys for pigs are modified by sanitary conditions. Furthermore, supplementation of diets with a blend of Trp, Thr, and Met + Cys AA improves performance, especially under salmonella-challenge and poor housing conditions. Dietary Trp, Thr, and Met supplementation can modulate immune status and influence resilience to sanitary challenges.
