The pharmaceutical effect of Korean wild ginseng residue extract on the performance, microbiota quality, cytokine expression, and the ginseng saponin content of laying hen.

In this study, a total of 312 Hyline brown laying hen of 1.92 ± 0.12 kg acquired at 24-wk old were employed to evaluate the pharmaceutical effect of Korean wild ginseng residue extract administered via drinking water on the performance, microbiota quality, cytokine expression, and the ginsenoside saponin (GS) content of laying hen for 12 wk.

Anti-Bordetella bronchiseptica effects of targeted bacteriophages via microbiome and metabolic mediated mechanisms.

Bordetella bronchiseptica poses a significant challenge in the context of respiratory infections, particularly in weanling pigs. In this study, we investigated the impact of a novel targeted bacteriophage in controlling B. bronchiseptica challenge (BBC) in an experimental design involving five distinct treatment groups: NC (no challenge), PC (BBC challenge), BF (10 pfu bacteriophage/kg diet + BBC), BN (2 × 10 pfu/day bacteriophage by nasal spray + BBC), and AT (antibiotic + BBC).

Effects of meal processing of black soldier fly on standardized amino acids digestibility in pigs.

The aim of this study was to investigate the effect of incorporating black soldier fly (BSF) larvae and its processed form as an alternative source of protein to fish meal (FM) on the digestibility of amino acids (AA) in weaned pigs. Four cannulated pigs with an initial bodyweight of 13.25 ± 0.

Exogenous protease influences protein digestibility, growth performance, and gut microflora in weanling pigs on a limited protein diet.

The study was conducted to evaluate the impact of dietary level of crude protein (CP) and protease supplementation on growth performance, digestibility of nutrients, intestinal morphology, and gut microbiota in weaning pigs. Three hundred cross-bred piglets (Duroc × Landrace × Yorkshire) were allotted to five dietary treatments on the basis of initial body weight (BW) and sex. Pigs were group-housed in pens with each treatment with 10 replicate pens with six pigs per pen.

Effect of wild ginseng on the laying performance, egg quality, cytokine expression, ginsenoside concentration, and microflora quantity of laying hens.

The experiment was carried out to study the effect of Korean wild ginseng adventitious root supplementation on the laying performance, egg quality, cytokine expression, ginsenoside concentration, and microflora quantity of Institut de selection Animale (ISA) brown laying hens at 24 weeks old. A total of 90 laying hens were subjected to a completely randomized design at three treatments, five repetitions and six laying hens per replicate. The experiments were divided by diets into the basic feed (CON), basic feed + 0.

The targeted anti-Salmonella bacteriophage attenuated the inflammatory response of laying hens challenged with Salmonella Gallinarum.

Fowl typhoid is a severe disease caused by Salmonella Gallinarum with considerable mortality and morbidity in laying hen farms. The current study has focused on controlling the infection in laying hens using anti-Salmonella spp. bacteriophage.

Calcium chloride is a better calcium source rather than calcium carbonate for weanling pigs.

Two experiments were conducted to evaluate the effects of calcium (Ca) levels in weanling pigs (Landrace × Yorkshire × Duroc). In experiment 1, one hundred and eighty weanling pigs were randomly allotted to one of the three treatments. The treatments were low (Ca 0.

Effects of various cooling methods and drinking water temperatures on reproductive performance and behavior in heat stressed sows.

The purpose of this study is to evaluate the effects of multiple cooling systems and different drinking water temperatures (DWT) on the performance of sows and their hair cortisol levels during heat stress. In this study, the effect of four different cooling systems: air conditioner (AC), cooling pad (CP), snout cooling (SC), and mist spray (MS), and two DWT, namely low water temperature (LWT) and high water temperature (HWT) on 48 multiparous sows (Landrace × Yorkshire; 242.84 ± 2.

Effects of dietary arginine in ameliorating the deleterious effects induced by mycotoxins on growth, immune system, body organs in growing pigs.

Mycotoxin contamination in pig feeds has a negative impact on growth performance, the immune system, and major body organs. Arginine (Arg) plays an important role in animals' body biochemistry and physiology. This study aimed to determine the effect of dietary Arg supplementation on mitigating the negative effects of mycotoxins in growing pigs.

Metabolic Responses of Dietary Fiber during Heat Stress: Effects on Reproductive Performance and Stress Level of Gestating Sows.

Heat stress is an important issue, and the addition of fiber to the diet is an option in modifying intestinal health. This study evaluated the effect of acid detergent fiber (ADF) levels on reproductive performance, intestinal integrity, and metabolism of gestating sows, and its carry-over effect on the lactation period during heat stress. The diets included 4.

Supplementation of nano-zinc in lower doses as an alternative to pharmacological doses of ZnO in weanling pigs.

A set of studies was performed to determine the influence of dietary ZnO concentration and source during two phases (days 0 to 14 and days 15 to 28). Experiment 1: 168 weaned piglets were allocated to four treatment groups in six replicates. The treatments included a basal diet without ZnO supplementation (control), 2,500 mg ZnO/kg (In2500), 500 mg nano-ZnO/kg (N500), and 150 mg nano-ZnO/kg (N150).
