Summary: The study found that supplementation with betaine in the diet increased the net portal appearance of essential and non-essential amino acids in Iberian pigs, thus increasing the availability of amino acids for peripheral tissues. However, supplementation with CLA decreased the net portal appearance of most essential amino acids.

Summary: The effects of adding a multi-enzyme mixture to diets deficient in various nutrients on the growth performance, bone mineralization, nutrient digestibility, and fecal microbial composition of grow-finish pigs were evaluated. The multi-enzyme mixture improved feed efficiency and bone strength but did not fully restore the growth performance of the pigs. It also increased the abundance of beneficial microorganisms in feces.

Summary: This research aimed to determine the standardized ileal digestible lysine requirement for 7-15 kg weanling pigs. The results showed a quadratic increase in growth performance and feed efficiency with increasing dietary lysine content, while plasma urea nitrogen decreased.

Summary: This study evaluated the effect of a phytogenic water additive (PWA) on the growth performance of nursery pigs fed with low-protein diets. Supplemental PWA increased the concentration of circulating essential amino acids and improved growth performance when dietary protein was adequate. PWA also had differential effects on blood calcium and its digestibility depending on the level of dietary protein.

Summary: This study investigated the effects of high-fiber and low-fiber diets on growth performance and intestinal oxidative stress parameters in growing-finishing pigs. The results showed that a high-fiber diet improved growth performance and maintained intestinal health by reducing intestinal oxidative stress.

Summary: This study aimed to evaluate the efficacy of synthetic methionine sources and determine the differences in growth rate of broiler chickens fed at or below requirements. Through database analysis and model fitting, it was found that there were no significant differences between linear and quadratic plateau models in determining methionine or sulfur amino acid requirements during different growth phases. Additionally, there was no difference in body weight gain response of broiler chickens to the two sources when fed at or below requirements for any of the growth phases.

Summary: The study found that increasing the intake of BCAA in protein-restricted diets can partially mitigate the negative effects on pig growth by improving IGF-I concentration and feed intake, which is associated with changes in serotonin receptors, blood amino acids, and hypothalamic NPY.

Summary: This study aimed to evaluate the effects of low-protein (LP) diets supplemented with sodium dichloroacetate (DCA) and glucose (GLUC) on metabolic markers and intestinal microbiota of finishing pigs. The results showed that DCA and GLUC supplementation improved hepatic lipid metabolism, but had limited effects on improving colonic microbiota profile of finishing pigs.

Summary: The purpose of this study was to compare the performance and nitrogen retention differences between immunocastrated (IC) and surgically castrated (SC) pure Iberian pigs. The results showed that IC males had higher levels of creatinine and IGF-1 compared to SC males and IC females. SC males were more prone to carcass fatness and insulin resistance. Overall, IC male Iberian pigs had better performance and nitrogen retention capacity.

Summary: This study investigated the effects of dietary energy level on the meat quality, amino acid, and fatty acid composition of different muscles in finishing pigs. The results showed that the growth performance of pigs was not significantly affected by the dietary energy level. Additionally, the LD and BF muscles responded differently to the dietary energy level, suggesting that a medium energy level could improve meat quality.

Summary: Supplementing enzymatically treated yeast (ETY) in piglet diet can partly improve the antioxidative status but has limited effect on growth performance.
The addition of enzymatically treated yeast (ETY) in the diet can promote gut health in piglets to a certain extent.
Further research is needed to investigate the long-term effect of enzymatically treated yeast (ETY) on growth performance.

Summary: Two experiments were conducted to determine the digestible energy (DE), metabolizable energy (ME), and the standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) in sorghum fed to pigs. The results showed that the DE and ME values can be predicted based on the content of tannin and ash in sorghum, while the SID of CP and AA can be predicted based on the content of tannin, ash, tryptophan, and fiber composition. These findings enrich the ingredient database and provide assistance for feed enterprises to make precise formulations when using sorghum as an ingredient.

Summary: The absorption of amino acids in blood after intake of different protein sources affects metabolism and utilization. Despite no clear categorization of protein sources into fast or slow proteins, soybean meal shows prolonged absorption compared to casein and hydrolyzed casein.

Summary: This study aimed to quantify the concentrations of ferulic acid and p-coumaric acid in a diet based on corn and soybean meal (SBM) and in feces from pigs fed this diet, as well as in a diet based on corn, SBM, and distillers' dried grains with solubles (DDGS) and in feces from pigs fed this diet. The results showed that the concentration of bound ferulic and p-coumaric acids was higher in the corn-SBM-DDGS diet and feces from pigs fed this diet compared to the corn-SBM diet and feces from pigs fed that diet.

Summary: This study used a meta-analysis approach to investigate the effect of Bacillus spp. supplementation on the growth performance of growing-finishing pigs. The results showed that the inclusion of Bacillus spp. in pig feed can increase average daily gain (ADG) and decrease the feed: gain ratio (F:G). The study also identified the number of animals per group as a factor contributing to the heterogeneity in ADG.
