    Interpretive Summary: Impact of prepartum administration of a vaccine against infectious calf diarrhea on nonspecific colostral immunoglobulin concentrations of dairy cows


    100x100 ASAS Blog Template (44)
    Unlike human babies, calves do not receive protective immune proteins (immunoglobulins) from the mother before birth, so a sufficient volume of immunoglobulin-rich colostrum of adequate quality must be consumed within hours of birth. It can be a challenge to meet this requirement for all dairy calves.

    Interpretive Summary: Short Communication: Supplementation with calcium butyrate causes an increase in the percentage of oxidative fibers in equine gluteus medius muscle


    100x100 ASAS Blog Template (35)
    The largest tissue in the body, skeletal muscle, is a heterogeneous mix of fibers that are categorized based on their primary source of energy production and speed of contraction. Evidence suggests that Thoroughbred horses with a greater percentage of type IIA, fast-twitch, oxidative fibers are more successful than those with fewer.

    Interpretive Summary: The impact of Zearalenone on heat-stressed skeletal muscle in pigs


    100x100 ASAS Blog Template (36)
    Heat stress (HS) and Zearalenone (ZEN), a toxic feed contaminant, affect growth, production efficiency, and animal welfare, and can cause death. As HS and ZEN independently increase oxidative stress, an imbalance of free radical production and clearance, and the likelihood of ZEN contamination during heat events, we hypothesized concomitant exposure would induce oxidative stress in pig skeletal muscle more than either agent alone.

    Interpretive Summary: Primary myoblasts from intrauterine growth-restricted fetal sheep exhibit intrinsic dysfunction of proliferation and differentiation that coincides with enrichment of inflammatory cytokine signaling pathways


    100x100 ASAS Blog Template (27)
    Myoblasts are stems cells whose functional capacity can limit muscle growth. However, stressful intrauterine conditions cause these cells to be intrinsically dysfunctional. This restricts muscle growth capacity, leading to intrauterine growth restriction (IUGR) of the fetus, low birth weight, and less muscle mass after birth.
