    Interpretive Summary: Bioactive supplements influencing bovine in vitro embryo development


    cow
    Ovum pickup and in-vitro production (IVP) of bovine embryos have quickly become commercial options for generating large quantities of transferable bovine embryos from genetically elite sires and dams. However, 2 limitations in this process still exist.

    Interpretive Summary: Increasing vitamin D levels to improve fertilization rates in cattle


    cattle
    Vitamin D is an important hormone that among other things, contributes to bone health, immunity, and reproduction. Recently, research has linked vitamin D to fertility in other species (primates), and therefore the objectives of the current research were to determine if mild supplementation with Vitamin D impacted fertility in female cattle.

    Interpretive Summary: Preovulatory follicle contributions to oocyte competence in cattle: importance of the ever-evolving intrafollicular environment leading up to the luteinizing hormone surge


    cow
    This review focuses on intrafollicular changes that occur within the dominant follicle from luteolysis to the LH surge and discusses recent advancements in the literature related to how such changes support oocyte competence.

    Interpretive Summary: Dose-response relationship between dietary choline and serum lipid profile, energy expenditure, and respiratory quotient in overweight adult cats fed at maintenance energy requirements


    cat
    Choline is an essential nutrient important for lipid metabolism in the liver of many mammals. In the present study, fourteen overweight cats had their commercial extruded cat food top-dressed with different amounts of choline chloride supplement.

    Interpretive Summary: Effects of bamboo leaf extract intervention on the growth performance, antioxidant capacity, and hepatic apoptosis in suckling piglets


    Suckling Pig
    Neonatal piglets suffer from severe birth oxidative stress due to the immaturity of their antioxidant system. In vitro and in vivo studies have now shown that the function of the antioxidant system can be modulated by bamboo leaf extract (BLE).

    Interpretive Summary: Constant light exposure in early life induces m6A-mediated inhibition of IGF gene family in the chicken


    Broiler Chicken
    Aberrant light exposure (such as light at night and super-intensity light) induces sleep disturbances and mood disorders, as well as major depressive disorder. In poultry, photoperiod is an important factor affecting the growth and behavior of broiler chickens.

    Interpretive Summary: Effects of particle size and phytase supplementation on apparent and standardized total tract digestibility of phosphorus in hybrid rye fed to growing pigs


    TS, growing pig, 100 x 100 (1)
    Cereal grains such as corn, wheat, and barley are widely used as an energy source in swine diets. However, due to their recent soaring prices, it is necessary to use alternative feedstuffs for swine. New commercial hybrid rye with improved ergot resistance and higher yield has been developed.

    Interpretive Summary: Effects of supplemental myo-inositol on growth performance and apparent total tract digestibility of weanling piglets fed reduced protein high-phytate diets and intestinal epithelial cell proliferation and function


    TS, piglet, 100 x 100 (2)
    After weaning, piglets undergo various kinds of stress that limit feed intake and nutrient digestibility. Much of the effects are strongest at the still-developing gastrointestinal tract where active feed digestion and nutrient uptake takes place.

    Interpretive Summary: Effects of dietary energy density and supplemental rumen undegradable protein on intake, viscera, and carcass composition of lambs recovering from nutritional restriction


    TS, lamb, 100 x 100
    Animal performance is determined by the combined effects of both prior and current nutrition. The present study used a 2 × 3 × 4 factorial to examine the effects of prior feeding level (HI or LO) on subsequent ad-libitum intake of diets varying in energy density (7.8, 9.2, 10.7 MJ/kg DM) and level of supplemental rumen undegradable protein (RUP; 0, 30, 60, and 90g/d).

    Interpretive Summary: Form of dietary selenium affects mRNA encoding cholesterol biosynthesis and immune response elements in the early luteal phase bovine corpus luteum


    TS, mRNA, 100 x 100
    In regions with soils deficient in selenium (Se), producers should supplement this trace mineral to the diet of forage-grazing cattle. We previously reported that circulating concentrations of progesterone (P4) are affected by the form of Se supplemented to cows.

    Interpretive Summary: Preovulatory follicular fluid and serum metabolome profiles in lactating beef cows with thin, moderate, and obese body condition


    TS, nursing beef cow, 100 x 100
    Extremes in body condition affect fertility and pregnancy outcomes in beef cows. Much research has been done in women and dairy cows to evaluate body condition’s effect on oocyte and embryo quality, pregnancy rates, and pregnancy outcomes.

    Interpretive Summary: Insights from two independent transcriptomic studies of the bovine corpus luteum during pregnancy


    TS, cattle production, 100 x 100
    Reproductive efficiency is necessary for the financial and environmental sustainability of cattle production. A critical component of this efficiency is the maintenance of pregnancy. The corpus luteum (CL) is a transient ovarian endocrine gland that produces progesterone—the hormone that maintains pregnancy in all mammals.

    TS, history, 100 x 100
    The corpus luteum (CL) forms on the ovary from the cellular remnants of the follicle following ovulation. The function of the CL is to produce progesterone that is required for successful pregnancy.

    Study finds plant-based protein not as nutritious as real meat


    TS, plant protein, 100 x 100
    A new study by researchers at Ohio State University found that human cells currently do not absorb the same level of nutrients from plant-based protein as they do from meat from animals. While plant-based proteins have risen in popularity, this study shines a light on how the body reacts differently when compared to meat.
