Using proteomics, immunohistology, and atomic force microscopy to characterize surface damage to lambskins observed after enzymatic dewooling.

The effects of conventional lime sulfide depilation and enzymatic depilation on the enamel layer of pickled lamb pelts were examined using atomic force and optical microscopy, immunohistological, and proteomic techniques. Microscopy showed that the surface structure of enzymatically depilated material was visibly less organized than conventionally processed material, implying that the enzymes used for depilation were responsible for this difference. Proteomic analyses identified an absence of collagen VI in the enamel of skins that had been processed with enzymes, in contrast to the skins that had been processed using conventional methods, which was confirmed using immunolocalization studies.

Influence of method of whole wheat inclusion and xylanase supplementation on the performance, apparent metabolisable energy, digestive tract measurements and gut morphology of broilers.

1. The aim of the present study was to examine the influence of whole wheat inclusion and xylanase supplementation on the performance, apparent metabolisable energy (AME), digesta viscosity, and digestive tract measurements of broilers fed on wheat-based diets. The influence of the method of whole wheat inclusion (pre- or post-pelleting) was also compared.

Influence of phytase and xylanase, individually or in combination, on performance, apparent metabolisable energy, digestive tract measurements and gut morphology in broilers fed wheat-based diets containing adequate level of phosphorus.

1. The aim of the present study was to examine the influence of microbial phytase and xylanase, individually or in combination, on performance, apparent metabolisable energy, digesta viscosity, digestive tract measurements and gut morphology in broilers fed on wheat-soy diets containing adequate phosphorus (P). The wheat-soy basal diet was formulated to contain 4.

Immunohistochemical detection of myogenic cells in muscles of fetal and neonatal lambs.

Previous studies have implied that myonuclei accumulation in a muscle is more important than myofibre number in the determination of muscle size in fetal/neonatal lambs. However, due to the lack of a reliable marker, the role of myogenic precursor nuclei (satellite cells) in myofibre hypertrophy in late fetal and postnatal life is not well understood. In this study, MyoD was shown to be a useful marker for actively proliferating satellite cells in both fetal and neonatal lambs.

Safety assessment of potential probiotic lactic acid bacterial strains Lactobacillus rhamnosus HN001, Lb. acidophilus HN017, and Bifidobacterium lactis HN019 in BALB/c mice.

The general safety of immune-enhancing lactic acid bacteria (LAB) strains Lactobacillus rhamnosus HN001 (DR20), Lb. acidophilus HN017, and Bifidobacterium lactis HN019 (DR10) was investigated in a feeding trial. Groups of BALB/c mice were orally administered test LAB strains or the commercial reference strain Lb.
