Summary: In this study, 6 phages were isolated and tested for their efficacy against E. coli strains isolated from diarrheal pigs. Phage therapy was found to significantly reduce fecal E. coli counts and restore the gut's bacterial composition. Additionally, giving phage cocktails resulted in higher average daily gain in piglets.

Summary: Bacteriophages are abundant at sites of bacterial colonization, but their ecology at sites of active infection remains unclear. In this study, we investigated bacteriophage populations in cell-free DNA collected from infection sites and found that phages reflect the relative abundance of their bacterial hosts at these sites. These findings may have implications for future investigative and diagnostic approaches utilizing phages and bacterial cell-free DNA.

Summary: Selection for hyper-prolific sows has led to increased litter size, decreased birth weight, and affected colostrum intake. Small pigs had higher lactobacilli counts, with colostrum quality and intake influencing total lactobacilli count.

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.

Summary: This study evaluated the effects of dietary supplementation with Lactobacillus plantarum on the growth performance, fecal microbial counts, gas emission, and nutrient digestibility in growing pigs. The results showed that supplementation with L. plantarum significantly improved the growth performance, fecal microbial counts, nutrient digestibility, and reduced the fecal ammonia concentration in growing pigs.

Summary: This study investigated the effects of diets with and without antibiotics supplementation and diets with different levels of crude protein on the growth performance and health of growing pigs. The results showed that antibiotics supplementation improved growth performance, antioxidant capacity, and reduced diarrhea incidence. Additionally, high crude protein diets also improved growth performance and loin muscle area.

Summary: The study confirmed that microbial additives producing antimicrobial substances and digestive enzymes can improve the health of weaning pigs by enhancing blood metabolites and fecal microflora. The optimal supplementation level of 1.0% was found to effectively enhance feed efficiency, blood metabolites, and fecal microflora.

Summary: The results of the experiment showed that Achyranthes japonica extracts (AJE) had positive effects on the growth performance, nutrient digestibility, and fecal microbiota of growing pigs, leading to increased body weight, average daily gain, and gain to feed ratio. Additionally, the AJE supplementation also improved the digestibility of dry matter and energy, increased lactic acid bacteria counts, reduced coliform bacteria counts, and decreased H2S emission in feces of growing pigs.

Summary: This study evaluated the effects of different ratios of soluble dietary fiber (SDF) to insoluble dietary fiber (IDF) on pig growth performance and microbial community. The results showed that in weaned pigs, the average daily gain (ADG) decreased and the feed intake to weight gain ratio (F/G) increased as the SDF to IDF ratio increased from 1:5 to 1:9. In growing-finishing pigs, the ADG showed quadratic changes as the ratios of SDF to IDF increased from 1:3 to 1:7. The Shannon index of fecal microbial diversity increased first and then decreased as the SDF to IDF ratio increased from 1:5 to 1:9. Overall, the recommended inclusion ratios of SDF to IDF in weaned and growing-finishing pig diets are 1:7 and 1:5.

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: The study investigated the effects of replacing antibiotic growth promoters (AGPs) with a mixture of egg immunoglobulin (IgY) and phytomolecules (PM) on weaned pigs. The results showed that the combination decreased the incidence of post-weaning diarrhea (PWD) and coliforms, improved feed conversion ratio, and enhanced intestinal histology and immune function.

Summary: This study found that xylanase (XYL) and xylo-oligosaccharide (XOS) had limited effects on pig performance, while faecal bacterial community composition significantly changed over time without an overall impact from the treatments.

Summary: This study found that supplementation with 1500 to 3000 units of bacterial phytase in diets based on corn and soybean meal can improve the daily weight gain and live weight of animals in the growing phase. Additionally, the use of phytase can reduce the use of phosphorus sources, improve environmental issues, and enhance the main zootechnical parameters of animal production.

Summary: This experiment investigated the effects of adding xylanase to wheat-soybean meal-based diets on the growth performance, nutrient digestibility, serum metabolites, and fecal microbiota in growing pigs. The results showed that supplementing xylanase improved the growth performance and nutrient digestibility in pigs, and increased the abundance of lactobacilli in fecal microbiota.

Summary: This study evaluated the effects of diets containing vitiviniculture waste on intake, digestibility, water balance, nitrogen balance, ingestive behavior, performance, and carcass traits of lambs. The results showed that feeding lambs with diets containing 216 g/kg cactus pear and 144 g/kg vitiviniculture waste resulted in higher intake and digestibility.

Summary: This study evaluated the efficacy of a novel phytase in terms of phytate hydrolysis and the digestibility of phosphorus and calcium in broiler chickens fed low and high phytate diets. The results showed that the phytase effectively hydrolyzed phytate and increased digestible phosphorus and calcium. The response to dietary phytate varied in terms of age and the specific nutrient being evaluated.
