The aim of this work was to investigate the serum biochemical profile, ileal amino acid (AA) digestibility, and expression of nutrient-sensing, hormone secretion, gastrointestinal (GIT) digestive enzyme and nutrient transporter genes in pigs subjected to dietary protein restriction. Twenty-four weaned pigs were distributed into three treatments, and the animals in each treatment were fed crude protein (CP) diets at one of three levels (20, 17, and 14%). Our results showed that pigs fed the 20% CP diet had greater (P < 0.05) average daily gain and ratio of feed to gain than those fed the 14% CP diet, but there were no differences between the 20% CP and 17% CP diets. Additionally, the 20% CP diet tended to upregulate (P < 0.05) the expression of nutrient-sensing-related genes, such as taste receptor type 1 member 1 (TasR1), calcium-sensing receptor (CaSR), and solute carrier family 1 (EAAC1), and the 17% CP diet tended to up-regulate (P < 0.05) the expression of digestive enzyme-related genes, hormone secretion-related genes, and nutrient transporter-related genes, such as pepsinogen, cholecystokinin type A receptor (CCK-1R), and dipeptide transporter 1 (PepT1), respectively. These results suggested that weaned pigs that were chronically fed a moderately restricted 17% CP protein diet could catch up to pigs fed a 20% CP diet in terms of growth performance and feed efficiency. In conclusion, the provision of 20% dietary CP was beneficial to the expression of nutrient-sensing and nutrient transporter genes in the GIT, and the provision of 17% dietary CP was beneficial to lipid metabolism and digestive enzymes in the GIT. www.impactjournals.com/oncotarget/

“…Regression of these variables with BW showed that CP intake declined at a rate of 7 g/day (r = 0.77) per each 10 kg BW, with a saving of feeding cost of 0.58€ (r = 0.75), from an initial value of 479 g/day in the control treatment. This suggests that incurring in a slight protein or amino acid restriction by feeding the finisher diet to 80 instead of 100 kg BW does not penalize growth performances while contributes to reducing N losses to environment as well as feeding costs in agreement with previous reports in heavy pigs (Daza et al, 2010;Gallo et al, 2014).…”

“…Besides, it would also reduce feeding costs and environmental contamination (Gallo et al, 2014 and2015). The aim of this study was to investigate the effect of providing the finisher diet at 100, 90 or 80 kg BW on performances and carcass, meat and fat quality of barrows and gilts intended for dry-cured products.…”

A total of 120 Duroc × (Large White × Landrace) pigs, 50% barrows and 50% gilts, with 54.1 ± 0.14 kg BW and 103 ± 3 days of age, were used to study the effect of advancing the shift to a standard finisher feed from 100 to 90 and 80 kg BW on production performances and carcass and pork quality. Each of the six treatments (two sexes × three BWs at time of feeding shift) was replicated four times and the experimental unit was the pen (with five pigs for growth performance and carcass variables and three pigs for pork and fat traits). The grower (163 g CP and 9.5 g total Lys/kg) and the finisher diets (152 g CP and 7.9 g total Lys/kg) were based on maize, barley and vegetal protein concentrates, contained 13.39 MJ metabolizable energy/kg and were offered ad libitum through the trial. Pigs intended for dry-cured product elaboration were slaughtered at 170 ± 3 days of age as average (124 and 115 kg BW for barrows and gilts, respectively). For the overall period, barrows ate more feed (P < 0.001) and grew faster (P = 0.03) than gilts. No effect of feed shift was observed on growth performances, although the average daily CP intake (P = 0.01) and feeding costs (P = 0.04) were reduced by advancing the transition to the finisher feed. Carcasses from barrows were heavier (P < 0.001) and had wider backfat depth (P < 0.001) than those from gilts but no significant differences were observed in the meat chemical composition. The feed change schedule did not modify carcass or meat traits. It is concluded that an early shift to the finisher feed (at 80 kg BW instead of 100 kg BW) might be an interesting strategy in pigs intended for dry-cured products because, although it neither increased body fatness nor improved pork quality, CP intake and feeding costs were reduced without impairment of growth performances. Results were similar for barrows and gilts.

“…It has been well documented that low crude protein (CP), amino acid (AA)-supplemented diets may reduce feed costs and nitrogen excretion (Kerr et al, 2003;Zarate et al, 2003;Fairbrother et al, 2005;Deng et al, 2007a;2007b;Lallès et al, 2007;Hou et al, 2008;Kang et al, 2008;Yue and Qiao, 2008;Deng et al, 2009;Opapeju et al, 2009;Gallo et al, 2014;Gloaguen et al, 2014;Liu et al, 2014;Recktenwald et al, 2014). Therefore, the CP level in the diet of weaned pigs has been suggested to be one of the main factors that affect their growth performance (Gallo et al, 2014), feed efficiency, and gastrointestinal health (Yin and Tan, 2010;Acciaioli et al, 2011).…”

Abstract:The effects of crude protein (CP) levels in the diet on the mRNA expression of amino acid (AA) transporters were studied in a 45-d trial. Eighteen piglets with an initial body weight (BW) of 9.57 kg were assigned to three groups (14%, 17%, and 20% CP in the diet) in a completely randomized design (six replicates per treatment). Diets were supplemented with crystalline AA to achieve equal standardized ileal digestible contents of Lys, Met plus Cys, Thr, and Trp, and were provided ad libitum. After 45 d, all piglets were slaughtered to collect small intestine samples. Compared with the values in the 14% CP group, the expressions of ASCT2, 4F2hc, and ATB 0 mRNA in the jejunum were increased by 23.00%, 12.00%, 6.00% and 48.00%, 47.00%, 56.00% in the 17% and 20% CP groups, respectively. These results indicate that a 14% CP diet supplemented with crystalline AA may not transport enough AA into the body and maintain growth performance of piglets. However, a reduction of dietary 17% CP may reduce the excretion of nitrogen into the environment while supporting the development of piglets. Therefore, the 17% CP level is more suitable than 14% CP level.
