“…Increasing dietary CP level tended to increase ADG during the carryover period, which was different from those piglets that were severely restricted in nutrient intake during the treatment period and had signi cant compensatory growth during the re-alimentation period [37,38]. The ability for compensatory gain depends upon the extent, timing and duration of nutrient restriction [39,40].…”

Background: With increasing concerns about antibiotic-resistant bacteria that pose a threat to human and animal health, in-feed antibiotics have been banned since 2006 in Europe and 2020 in China. However, previous studies on crude protein (CP) and amino acids (AA) requirements of pigs were mostly based on the diets with antibiotics. The objective of this study was to evaluate the effects of CP supply on growth performance, body composition and tissue deposition for piglets fed diets with or without antibiotics. Methods: A total of 250 newly weaned piglets were randomly assigned to 1 of 10 dietary treatments (5 replicate pens per treatment with 5 animals per pen) in a 5 × 2 factorial arrangement with 5 CP levels (16, 18, 20, 22, 24 %) and 2 antibiotic supplementations (with or without antibiotics). Treatment diets were fed for 14 d to test treatment effects, and then a nursery diet (19% CP) without antibiotics was fed to all piglets until they had an average body weight of 25 kg to determine if carryover effects of treatment diets existed. An additional 5 piglets at the start were slaughtered to determine initial body composition. At the end of each period, 1 pig close to the average BW of each pen was slaughtered to determine body composition and tissue deposition.Results: Increasing dietary CP level linearly improved (P < 0.05) average daily gain (ADG), average daily feed intake (ADFI), and gain:feed (G:F) during the treatment period, while antibiotics tended to improve ADG of piglets (P < 0.10). The ADG during the carryover period tended to be improved (P < 0.10) with the increase of dietary CP level, but there was no difference in ADG during the entire nursery period (P > 0.10). Neither CP level nor antibiotic supplementation affected (P > 0.10) the incidence of diarrhea in each period. With the increase of dietary CP level, weights of fasted body, empty body, eviscerated carcass, and organs at d 14 were linearly improved (P < 0.05). Neither CP level nor antibiotic supplementation had a significant effect on the physical body composition of pigs at the end of the nursery period (P > 0.05). Body protein content at d 14 linearly improved (P < 0.05) with increasing CP level, whereas body ash content, lipid:protein and ash:protein ratio linearly decreased (P < 0.05). Increasing dietary CP level resulted in a greater (P < 0.05) deposition rates of body water and protein during the treatment period, while antibiotics tended to increase (P < 0.10). There was no effect (P > 0.05) of CP level or antibiotic supplementation on the chemical body composition at the end of the nursery period. However, increasing CP level quadratically improved (P < 0.05) deposition rates of body water, protein and lipid during the carryover period as well as deposition rates of protein, lipid and ash during the entire nursery period. According to the model with the minimum AIC, the CP requirement based on ADG was 23.01 and 22.65%, and based on protein deposition (PD) was 24.00 and 23.29% for antibiotic-free diet and antibiotic diet, respectively. Conclusions: Increasing dietary CP level increased the growth performance and protein deposition of piglets during either the treatment period or the carryover period. The CP requirement for piglets with high health status fed antibiotic-free diet was slightly higher than those fed antibiotic diet.

Two experiments were conducted to elucidate the nitrogen (N) balance of pigs exhibiting compensatory growth when changing the dietary lysine levels from deficiency to sufficiency. Experiment 1 elucidated whether pigs exhibited compensatory growth with dietary lysine sufficiency. Twenty 6-week-old males were assigned to one of two treatments: control and LC (lysine and control). Control pigs were fed a control diet throughout the 24-day experimental period, whereas LC pigs were fed a low lysine diet until day 21 of the experiment, followed by the control diet until the end of experiment. The dietary lysine sufficiency treatment induced an 80% increase in the growth rate of LC pigs (P < 0.05). Experiment 2 focused on the N balance of pigs that exhibited compensatory growth with dietary lysine sufficiency. Eighteen 6-week-old males were assigned to one of three treatments: control, LC, and LL (low lysine). LL pigs were fed a low lysine diet throughout the 24-day experimental period. Pigs that exhibited compensatory growth with dietary lysine sufficiency tended to retain a higher amount of N than control pigs (P = 0.10). These finding suggest that the compensatory growth induced in pigs by dietary lysine sufficiency was partly attributable to a higher level of N retention.

“…These studies indicate that sufficiency in dietary protein and amino acid contributes to triggering compensatory growth in pigs. However, compensatory growth was only observed in some studies (Chaosap et al 2011, Martínez-Ramírez et al 2009, Martinez-Ramirez et al 2008, O'Connell et al 2006; in other studies, compensatory growth was incomplete or absent (Chiba et al 1999, Pond & Mersmann 1990, Skiba et al 2001, Yang et al 2008a. Therefore, how compensatory growth can be induced and the underlying mechanisms remain to be elucidated.…”

“…Numerous studies have since examined compensatory growth in growing pigs that have been subjected to restricted feed intake or protein restriction (Chaosap et al 2011, Fabian et al 2002, Heyer & Lebret 2007, Oksbjerg et al 2002. In these studies, compensatory growth was explored as a means of improving carcass meat quality, nutrient utility, and nitrogen excretion and thus improving pork production efficiency.…”

This review describes our studies on compensatory growth, specifically the growth that occurs after dietary lysine deficiency is changed to sufficiency. We found that dietary lysine sufficiency induced compensatory growth in pigs after dietary lysine deficiency. We also showed that compensatory growth of pigs induced by dietary lysine sufficiency was partly attributed to greater N retention. In a rat model, both suppression of proteolysis and increased protein synthesis in skeletal muscle contributed to their compensatory growth with lysine sufficiency. Finally, our in vitro studies with cultured skeletal muscle cells revealed that the compensatory growth in these cells was induced by increased lysine levels in combination with the modulation of insulin-like growth factor-I and glucocorticoid levels. This suggested that compensatory growth in pigs and rats with lysine sufficiency was due to both increased serum lysine levels and changes in the levels of hormones involved in protein synthesis and degradation.
