Summary: This study evaluated the impact of supplementing glutamic acid to reduced protein diets on the growth performance of weanling pigs. The results showed that supplementing glutamic acid enhanced the body weight, average daily gain, and gain-to-feed ratio of the weanling pigs. The study also observed a linear increase in these growth parameters with increasing levels of glutamic acid. Additionally, the supplementation of glutamic acid had an effect on ammonia and methyl mercaptans emissions.

Summary: Exogenous proteases have the potential to enhance the use of low-protein diets in broilers. The study found that reducing dietary crude protein levels negatively affected the growth and slaughter performance as well as the immune capacity of broilers, but improved the digestibility of amino acids. However, the addition of exogenous proteases improved the weight gain and feed efficiency of broilers.

Summary: The production performance and meat quality of slow-growing hybrid chickens were monitored under different diets with varied protein content. The chickens fed with diets supplemented with crude protein showed better growth, slaughtering traits, and meat quality compared to those fed with standard diets.

Summary: Three new certified reference materials (CRMs) for crude protein, crude fat, and crude ash in animal feed were developed and characterized. The measurement methods were optimized and validated using existing CRMs. The certified values and uncertainties were determined through multiple laboratories, proving the suitability of these CRMs for evaluating quality control in feed testing laboratories.

Summary: This study synthesized a microbial consortium to produce efficient crude enzyme for the hydrolysis of Chinese distillers' grains (CDGs). The hydrolysis damaged the lignocellulose and decreased its crystallinity. Through two pathways, the true protein content of CDGs significantly increased, with the second pathway demonstrating higher economic benefits.

Summary: In this experiment, it was found that pharmacological levels of Zn or sodium diformate independently improved nursery pig performance, while low dietary protein had an impact on fecal dry matter. However, the effect of dietary protein was less significant when zinc oxide was present in the diet.

Summary: The study aimed to reduce production cost and increase tilapia yield through a feeding regime. The trial involved four treatments with three replications, using different feeding frequencies for male Nile tilapia. The results showed that fish fed twice per day every other week had the highest growth performance, lowest production cost, and highest benefit-cost ratio.

Summary: Supplementing increasing levels of Glu to low CP diets did not have linear or quadratic effects on growth performance and nutrient digestibility. However, there was a trend of increased serum creatinine concentration in pigs fed the NC diet with the increase in Glu supplementation. Backfat thickness and lean percentage tended to decrease in pigs fed the NC diet, with quadratic responses observed with the increase in Glu supplementation.

Summary: The study found that pelleted native grass diets (GP and GPC) were more beneficial for the growth performance and rumen microbiota of lambs compared to non-pelleted native grass hay diet (HA). The results also suggest that the rumen microbiota varied in response to different feed types, with distinct differences observed among the groups.

Summary: This study investigated the effects of reduced protein and feed form on broiler performance. The results showed that reducing dietary protein content can reduce ammonia concentrations in litter. Mash diets were favorable in terms of litter quality and welfare, but they could not maintain the same performance and slaughter yield as pelleted diets.

Summary: This study investigated the effects of individual amino acid deletions on the growth performance, carcass traits, and nutrient utilization of poultry. The results showed that certain amino acid deficiencies had negative impacts on performance and carcass traits of the birds, with Val and Arg being co-limiting in wheat-soybean meal diets.

Summary: This study found that dietary shrimp soluble extract can improve the growth performance, non-specific immune responses, and disease resistance in juvenile Nile tilapia. However, the addition of inosine monophosphate did not provide additional benefits to this ingredient. Further research is needed to better understand the effects of fishery by-products and inosine monophosphate on fish diets.

Summary: The study investigated the effects of different diets containing fish meal and fish meal analog on juvenile Japanese eel, determined the optimum level of fish meal analog as a substitute for fish meal protein, and evaluated the immunostimulant effects of natural feed additives. The results showed that fish meal analog could replace up to 10% of fish meal protein without compromising growth and health of the fish, and the additives could improve the replacing rate of fish meal analog without affecting the fish's growth and health.
