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.

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 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.

  • A study tested the effects of four different zinc diets on the health and digestion of 20 weaned piglets over two weeks, comparing a negative control and three zinc treatments (standard, chelate, and nanoparticle forms).
  • The results showed that the negative control had the poorest diarrhea scores and nutrient digestibility, while the zinc treatments, particularly the nanoparticle form, led to improved intestinal health and immune responses.
  • Overall, low levels of nanoparticle ZnO were found to have similar beneficial effects as traditional zinc oxide, suggesting it could serve as an effective alternative to enhance nutrient absorption and gut immunity in weaned pigs.

The effects of arginine (Arg) and methionine (Met) supplementation on nutrient use in pigs were determined under hot season conditions. A total of five experimental diets including basal diet (CON) were supplemented with two types of amino acids (Arg and Met) and two different amounts of amino acids (0.2% and 0.

Silk fibroin (SF) is known to be a biocompatible material, and different forms of SF are used for various applications. However, the application of SF in particle form is rarely reported, compared to other forms. In this study, SF microparticles with a diameter of approximately 250 μm were prepared by the electrospray method, using 1 M LiCl/DMSO as a solvent.

Phosphatidylcholine (PPC) and sodium deoxycholate (DC) injections have been used cosmetically to reduce localized fat, but to date, few studies have addressed the histological effect of human fat tissue following injections of PPC and DC. We injected PPC and DC mixed with normal saline into the patient's abdominal area. Examinations of postinjection tissue revealed marked changes within the subcutaneous fat.

Although the technique for extracting the Bombyx mori sericin has been extensively known, the extraction of sericin from wild-silkworm cocoons is not yet standardized. The aim of this study was to find the optimal conditions for the extraction of sericin from Antheraea mylitta cocoons, with high yields and minimum degradation. We attempted to apply various protocols for the extraction of the A.

  • The study aimed to assess the effectiveness of umbilical cord serum (UCS) eye drops on corneal healing and haze in mice with chemical burns, comparing them to peripheral blood serum (PBS) and artificial tears (AT).
  • The results indicated that the UCS eye drops led to faster healing of corneal wounds and less haze compared to both PBS and AT at various time points during the treatment.
  • Histological analysis confirmed that UCS-treated mice had better epithelial integrity and lower inflammation, and UCS also resulted in lower levels of a specific inflammatory marker (IL-1β) compared to PBS.*

  • - The study examined the effects of 20% umbilical cord serum eyedrops on recovery after laser epithelial keratomileusis (LASEK) in 60 myopic patients, comparing results with a control group receiving only standard treatment.
  • - Results indicated no significant difference in visual acuity or refraction between the two groups, but those using cord serum experienced a shorter epithelial healing time and lower haze scores at 2 and 4 weeks.
  • - The findings suggest that adding umbilical cord serum eyedrops post-surgery can enhance corneal healing and improve tear film quality compared to conventional treatment alone.

Four regenerated silk fibroin (SF) samples were prepared under different dissolution conditions and their molecular weight (MW) distributions and solution properties in water and formic acid were examined. SFL, produced by dissolving in LiBr aqueous solution for 6h, showed the highest MW level. In the three SFC samples, produced by dissolving SF in CaCl(2)/H(2)O/EtOH solution for dissolution times ranging from 3 to 180 min, the MW of the SFs decreased with increasing dissolution time and a new band appeared at low MW.
