“…A total of twenty large White × Landrace castrated piglets from five litters were weaned at 21 d of age (5·3 ( sem 0·13) kg) and assigned randomly to one of the two treatment groups (ten pigs/group), representing dietary supplementation with 0·0 % control or 1 % l -arginine (Table 1). Piglets were individually housed in 1·3 × 1·2 m pens with slotted stainless steel floors ( 35 ) . Each pen was equipped with a feeder and a nipple waterer.…”

Oral administration of L-arginine has been reported to prevent gut disease in human infants. However, little is known about the effects of dietary arginine supplementation on intestinal development of weaned piglets. In the present study, twenty 21-d-old castrated piglets with 5·3 (SEM 0·13) kg body weight (BW) were weaned from sows, individually housed and randomly assigned to one of the two maize-and soyabean meal-based diets supplemented with 0 or 1 % L-arginine. After consuming the diets for 7 d, six pigs were randomly selected from each group to obtain various tissues. Compared with control pigs, dietary supplementation with 1 % L-arginine did not affect feed intake but enhanced (P,0·05) the relative weight of the small intestine (þ 33 %), daily BW gain (þ38 %) and feed efficiency (þ28 %). The villus height of the duodenum, jejunum and ileum in arginine-supplemented piglets was 21, 28 and 25 % greater (P,0·05) than in the nonsupplemented control group. Arginine supplementation increased (P,0·05) protein levels for vascular endothelial growth factor (VEGF) in duodenal, jejunal and ileal mucosae by 14, 39 and 35 %, respectively. Compared with the control group, dietary supplementation with 1 % L-arginine increased (P,0·05) plasma concentrations of arginine and insulin (þ 36 %), and decreased (P,0·05) plasma concentrations of cortisol (2 33 %), NH 3 (2 21 %) and urea (219 %). These results indicate that arginine supplementation enhances intestinal growth, development and expression of VEGF in early-weaned pigs fed a maize-and soyabean meal-based diet. The findings may have important implications for neonatal pigs under stressful or diseased conditions.

“…At present, little is known about effects of TRP on (a) pregnancy or lactation, which are important events in the mammalian life (108-111); (b) cellular signaling, which is a major mechanism for metabolic control (112-119); or (c) gene expression (including epigenetics), a highly specific process in which a gene can be switched on or off in response to regulatory factors (120). With the recent developments of omics techniques (e.g., genomics, proteomics, and metabolomics) (121)(122)(123)(124)(125)(126)(127)(128) and bioinformatics (126), researchers now have powerful tools to study regulatory roles for TRP in gene and protein expression. Such a revolutionary approach is expected to rapidly provide new and comprehensive information about TRP metabolism and nutrition in organisms under both physiological and pathophysiological conditions.…”

Tryptophan metabolism in animals important roles in nutrition and health

L-Tryptophan is a nutritionally essential amino acid for monogastric animals and preweaning ruminants because it cannot be synthesized in the body. Besides serving as a building block for proteins, tryptophan is a critical nutrient for the functions of nervous and immune systems. Over the past decades, much attention has been directed to study the role of tryptophan as a limiting amino acid in mammalian and avian nutrition. However, emerging evidence from recent studies shows that tryptophan and its metabolites (e.g., serotonin (5-hydroxytryptamine, 5-HT) and melatonin)) can regulate feed intake, reproduction, immunity, neurological function, and anti-stress responses. Additionally, tryptophan may modulate gene expression and nutrient metabolism to impact whole-body homeostasis in organisms. Thus, adequate intake of this amino acid from the diet is crucial for growth, development, and health of animals and humans.

“…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.
