    Interpretive Summary: Evaluation of sow thermal preference across three stages of reproduction


    Heat sow connection
    A paper recently published in the Journal of Animal Science evaluated whether different reproductive stages of sows altered thermal preference and if current recommendations required updating. It was hypothesized that the reproductive stage would alter thermal preference in sows. This study is the first to look at temperature preference differences based on the reproductive stage of sows.

    Interpretive Summary: Detecting effective starting point of genomic selection by divergent trends from BLUP and ssGBLUP in pigs, beef cattle, and broilers


    Genomic selection
    A paper recently published in the Journal of Animal Science aimed to find the start date of genomic selection for a set of economically important traits in pigs, Angus cattle, and broiler chickens by comparing trends obtained using best linear unbiased prediction and single-step genomic best linear unbiased prediction.

    Interpretive Summary: Effects of guanidinoacetic acid supplementation on nitrogen retention and methionine flux in cattle


    cattle herd
    The research team from Kansas State University hypothesized that guanidinoacetic acid supplementation to Metdeficient cattle would induce a methyl group deficiency and that methionine supplementation would reduce the methyl group deficiency. Additionally, it was thought that guanidinoacetic acid might improve nitrogen retention when methionine was supplemented.

    Interpretive Summary: The impact of direct-maternal genetic correlations on international beef cattle evaluations for Limousin weaning weight


    Limousin cow
    Maternally influenced traits include genetic factors that impact birth and weaning. Cultivating a better understanding of the heritability of maternally influenced traits may improve estimated breeding values (EBV), genetic selection and ultimately productivity.

    Interpretive Summary: Piglet birth weight increases, and litter size decreases, with compensatory feeding of sows


    Piglet birthweight
    High backfat is not a desired trait in finisher pigs. Backfat thickness can vary depending on the season when piglets are born. Sows with high weight loss after summer lactation, for instance, yield smaller pigs with higher backfat thickness at harvest.

    Interpretive Summary: Review: optimizing genomic selection for crossbred performance by model improvement and data collection


    breeding program
    Crossbreeding enables breeders to capitalize on heterosis, which is the phenomenon of superior average performance of crossbreds compared with the average performance of their parental lines. Breeding programs aiming to improve the performance of crossbreds may benefit from genomic prediction of crossbred performance for purebred selection candidates.

    Interpretive Summary: Wingless-type mouse mammary tumor virus integration site regulation of bovine theca cells


    Bovine Theca Cells Image
    The results of the present study, outlined in the full paper, support the idea that the WNT signaling pathway is involved in the regulation of theca cell proliferation and steroidogenesis, but further research is required to explain the specific mechanisms of action and dose responses of WNT, Dickkopf, and secreted frizzled-related protein 4 and their relationship with other molecules during follicular growth. A better understanding of the role of WNT and their molecular mechanisms will allow for a greater perspective on how these signals impact follicular maturation and subsequent conditions that could lead to ovarian cysts.

    Interpretive Summary: Addition of dietary methionine but not dietary taurine or methyl donors/receivers to grain-free diet increases postprandial homocysteine concentrations in adult dogs


    adult dog
    Grain-free diets have been popular in the pet industry for over a decade; however, recently, they have been associated with canine dilated cardiomyopathy (DCM). Research has linked DCM with a deficient of taurine in cats, which may be a possible cause for DCM in large breed dogs. Methionine and cysteine, amino acid precursors to taurine synthesis in dogs, is very low in ingredients used to replace grains. To date, there has been no research evaluating the plasma and whole blood taurine concentration of dogs when feeding grain-free diets supplemented with nutrients involved in the biosynthesis of taurine.

    Interpretive Summary: The impacts of xylanase on the fermentability and digestibility of high insoluble fiber diets in growing pigs


    growing pig
    Adding coproducts to swine feed is an economical choice that can also adversely impact the digestibility of feed. Coproducts contain a higher amount of non-starch polysaccharides (NSP), which cannot be digested by pigs. Poorly digested feed leads to reduced performance, an undesired effect. Adding carbohydrase enzymes to feed may make NPS more digestible without negatively impacting performance.

    Interpretive Summary: Effects of induced hindgut acidosis in growing pigs on growth, intestinal morphology and inflammation


    baby pigs
    Hindgut acidosis was induced by continuously infusing glucose (GLC) or casein (CAS) into the terminal ileum of growing pigs. Pigs were separated into three groups and given either an infusion of water (control), dextrose 50% (GLC) or casein sodium salt (CAS). Average daily feed intake was reduced in GLC and CAS pigs compared to the control.

    Interpretive Summary: Thermoregulatory and physiological responses of nonpregnant, mid-gestation, and late-gestation sows exposed to incrementally increasing dry bulb temperature


    sow
    Results of the present study demonstrated that, when compared with mid-gestation and nonpregnant sows, late-gestation sows had increased respiration rate and altered blood characteristics in response to increasing dry bulb temperature, which can be indicative of greater heat stress sensitivity.

    New Lawsuit Against USDA Gene-Editing Approvals


    Biotech
    In 2020, The United States Department of Agriculture (USDA) issued its final rule to modernize agricultural biotechnology regulations. The rule was revised to enable USDA’s Animal and Plant Health Inspection Service (APHIS) to regulate organisms developed using genetic engineering for plant pest risk with greater precision and reduces regulatory burden for developers of organisms that are unlikely to pose plant pest risks.

    “It is abundantly clear that getting vaccinated is the single most effective thing we can do to protect ourselves, our families, and our communities,” CEO Donnie King said in a memo to employees. Tyson Foods is incentivizing workers with a $200 bonus to do so, on top of the already established policy of providing up to four hours of pay for getting vaccinated outside of work.

    Study Finds Decline in American’s Confidence in US Institutions

    This survey, which sampled over 1,380 adults living in all US states and the District of Columbia during the current survey set, began in 1973 during the Watergate scandal. Since 1993, Gallup has tracked 14 core institutions and the public’s confidence. During the last 15 years, confidence has remained below 36%. Before 2006, confidence was typically above 40%.

    "Life expectancy has been increasing gradually every year for the past several decades," Elizabeth Arias, a CDC researcher who worked on the report, told Reuters. "The decline between 2019 and 2020 was so large that it took us back to the levels we were in 2003. Sort of like we lost a decade."

    After the disappointing rejection from the U.S. Supreme Court, the U.S. Court of Appeals for the Ninth Circuit had denied the petition from the National Pork Producers Council (NPPC) and the American Farm Bureau Federation (AFBF) to rescind California’s Proposition 12 (Prop 12) as unconstitutional under the dormant Commerce Clause.

    Groups Push for Massachusetts to Delay Animal Confinement Law


    Delay
    The National Pork Producers Council (NPPC) and the North American Meat Institute (NAMI) are advising Massachusetts to defer implementation of the Act to Prevent Cruelty to Farm Animals (the Act). With just five months until enforcement, NPPC and NAMI state that the Attorney General for the state is 19 months late in providing rules and regulations for the Act to farmers and producers.
