This study aimed to evaluate the effects of mono- and multi-strain lactic acid bacteria (LAB) probiotics on the growth performance, nutrient digestibility, blood profiles, fecal noxious gas emission, intestinal microbiota and intestinal morphology of weaning pigs challenged with or without () and (SE). In Exp. 1, a total of 60 crossbred weaning pigs were randomly allotted to one of five dietary treatments.

The objective of this study was to evaluate predictions of digestibility at each age (puppy, adult, and senior) in dogs of dry matter (DM), organic matter (OM), crude protein (CP), gross energy (GE), crude fiber (CF), and ether extract (EE) using dog diets. First, to determine the digestibility of dog diets using pepsin and pancreatin incubations, conduct the method. Later, 18 mixed-sex beagles were used in this experiment to compare digestibility.

This study investigated the effects of lairage conditions on the welfare and meat quality of pigs during lairage periods. A total of 3070 finishing pigs were assigned to one of six groups arranged in two trials in a 2 × 3 factorial design according to the illuminance (under 40 lux (LX), over 40 lux (HX)) and stocking density (low density (LD), higher than 0.83 m/100 kg; normal density (ND), 0.

In Experiment 1, a total of eighteen crossbred ([Landrace × Yorkshire] × Duroc) barrows with an initial body weight of 6.74 ± 0.68 kg were randomly divided into three dietary treatments (one pig per cage and six replicates per treatment) and housed in metabolic cages that were equipped with a feeder and slatted floor to collect urine and feces.

This study was conducted to investigate the effects of protease supplementation and different nutrient density of diets in growing-finishing pigs. A total of one hundred-eight crossbred growing pigs ([Landrace × Yorkshire] × Duroc) with an initial body weight (BW; 18.74 ± 3.

There are several factors that affect the welfare and meat quality of pigs during pre-slaughter transport. Among various factors, the effects of weather conditions and loading density were studied. A total of 3,726 finishing pigs were allotted to one of nine groups arranged in a 3 × 3 factorial design according to the weather conditions (low temperature [LT], under 10°C; normal temperature [NT], 10°C-24°C; high temperature [HT], upper 24°C), and loading density (low density [LD], upper 0.

Selenium (Se) is an essential trace mineral that plays an important role in physiological processes by regulating the antioxidant defense system and enhancing immunity. Chromium is an essential mineral involved in carbohydrate and lipid metabolism and also plays a role in maintaining normal insulin function. Based on these advantages, we hypothesized that the addition of selenomethionine (SeMet) and organic chromium (OC) to broiler diets would increase Se deposition, antioxidant capacity and immune response in meat.

This study investigated the effect of processed forms (defatted or hydrolyzed) of black soldier fly larvae ( L., BSFL) as a protein substitute on broilers. Experiment 1 was a feeding experiment, and Experiment 2 was a metabolism experiment.

Animal welfare during transport became an largely issue because of increasing demand for improved animal welfare standards. Most studies on the animal welfare during transportation have concentrated on the atmosphere and the temperature of the truck compartments. Thus, the objective of study was to collect and quantify three axis acceleration and determine the effect of bedding for transporting pigs from farm to slaughterhouse.

In order to make piglet diets more effective, it is necessary to investigate effective methods for breaking down xylan in cereal. The objective of this study was to determine the effects of dietary stimbiotic (STB) supplementation on growth performance, intestinal morphology, immune response and intestinal microbiota in weaned piglets. A total of 24 (Duroc × Yorkshire × Landrace) weaned pigs (initial body weight of 8.

Article Synopsis
  • The study aimed to assess how toxin binders impact broiler breeders exposed to an ochratoxin A (OTA)-contaminated diet over a 9-week period, including an adaptation week.
  • A total of 60 female Arbor Acres broiler breeders were divided into six treatment groups to evaluate different toxin binder formulations alongside a control group with OTA exposure.
  • Results indicated that the positive control group faced detrimental effects on egg production, hatchability, organ weight, and liver health; however, toxin binder supplementation significantly improved eggshell strength and other health metrics by the end of the study.

Article Synopsis
  • - The study focused on the impact of probiotics on weaned piglets challenged with bacterial pathogens, specifically targeting enteric diseases like post-weaning diarrhea.
  • - Two experiments were conducted: Experiment 1 involved 90 piglets assigned to different treatment groups over 2 weeks, while Experiment 2 utilized 30 piglets over 4 weeks to further assess the effects of various probiotics.
  • - Results showed that adding two specific probiotics (LA and 38W) significantly improved growth performance and reduced harmful intestinal bacteria, as well as decreased diarrhea and unpleasant odors in piglets.

Article Synopsis
  • The study evaluated the impact of exogenous protease on various factors in broilers, including performance, nutrient digestibility, and economic outcomes, using 90 Arbor Acres chickens divided into three dietary treatment groups.
  • The group that received the protease supplement showed improved growth performance and better intestinal morphology compared to the group with a nutrient-deficient diet alone, while also achieving lower fecal scores and higher digestibility of protein and amino acids.
  • Although there were no significant changes in carcass yields or organ weights, the addition of protease was found to reduce feed costs and enhance profit margins, suggesting it can be an effective economic supplement for broiler diets.

Objective: The aim of the present study is to identify the factors that affect retention in outpatients with psychiatric disorders as indicators of treatment adherence, including Minnesota Multiphasic Personality Inventory (MMPI) scores.

Methods: The medical records of 146 patients diagnosed with major depressive disorder, bipolar disorder, or anxiety disorder for at least 10 years and discharged were retrospectively reviewed in the present study. The subjects were categorized based on the duration of outpatient treatment as < 6 months (L6) or ≥ 6 months (M6) groups and reclassified as < 36 months (L36) and ≥ 36 months (M36) groups.
