    Interpretive Summary: Extending lactation length: consequences for cow, calf, and farmer


    100x100 ASAS Blog Template (59)
    Traditionally, a 1-yr calving interval is advised to dairy farmers to realize a yearly peak in milk yield. A 1-yr calving interval, however, implies a yearly event of drying-off, calving, and start of lactation, which are all associated with an increased risk for diseases and disorders.

    Interpretive Summary: In utero hyperthermia in late gestation derails dairy calf early-life mammary development


    100x100 ASAS Blog Template (58)
    Late-gestation in utero heat stress in dairy cattle negatively affects the mammary microstructure and milk yield at maturity, but investigation into early-life windows of mammary development is needed to fully characterize the lifelong consequences of intrauterine heat stress on the mammary gland (MG).

    Interpretive Summary: Effects of diet on feed intake, weight change, and gas emissions in beef cows


    100x100 ASAS Blog Template-7
    The beef cow utilizes about 74% of total feed energy required to produce beef. Therefore, a more thorough understanding of feed intake, weight gain, and feed efficiency traits in the beef cow is fundamental to reducing cost and improving the environmental footprint of beef production.

    Interpretive Summary: Effects of dietary protein content and crystalline amino acid supplementation patterns on growth performance, intestinal histomorphology, and immune response in weaned pigs raised under different sanitary conditions


    100x100 ASAS Blog Template-10
    Reducing dietary crude protein (CP) content reduces nitrogen excretion to the environment and undigested protein availability to enteric pathogens in the hind gut resulting in reduced postweaning diarrhea and improved gut health. To meet the amino acid requirements in low CP diets, supplementation of essential amino acids in nursery diets is necessary, and the availability of more feed-grade crystalline amino acids allows low CP diets to be practically formulated.

    Interpretive Summary: Replacement of dietary corn with corn bran plus condensed distillers solubles effects on feedlot growth performance and carcass trait responses of beef steers


    100x100 ASAS Blog Template-9
    Dry-corn milling biorefineries have the opportunity to install technology to fractionate corn prior to fermentation, which creates a product stream of fibrous bran that can be fed to cattle. The objective of this study was to determine the effects of replacing dietary corn with corn bran and condensed distillers solubles (CBCDS) or wet-corn gluten feed (WCGF) on growth performance, efficiency of dietary net energy (NE) utilization, and carcass characteristics in finishing steers.
