    Interpretive Summary: Gilt development to improve offspring performance and survivability


    TS, suckling calf, 100 x 100 (1)
    Proper gilt development influences offspring performance and survivability by increasing gilt longevity and colostrum and milk production. Gilt development success starts in selecting gilts heavier than 1 kg at birth, prioritizing colostrum and milk intake, and weaning at 24 d of age or older.

    Interpretive Summary: Effects of administration of a growth promoting implant during the suckling phase or at weaning on growth, reproduction, and ovarian development in replacement heifers grazing native range


    TS, suckling calf, 100 x 100
    Management of beef females during the first year of life can impact fertility and reproductive longevity. Cattle producers can improve calf weight gains by using growth promoting implants; however, to be applicable, they must not negatively impact heifer reproductive performance or development.

    Interpretive Summary: Genetic relationships between efficiency traits and gut microbiota traits in growing pigs being fed with a conventional or a high-fiber diet


    TS, pig digestion, 100 x 100
    The link between the composition of the gut microbiota, i.e the composition of microorganisms in the gut, in pigs and their feed efficiency, i.e. their ability to utilize nutrients, as well as their ability to digest were studied from a genetic point of view.

    Interpretive Summary: Model definition for genetic evaluation of purebred and crossbred lambs including heterosis


    TS, crossbred lamb, 100 x 100
    Crossbreeding is common in commercial sheep enterprises. It allows breeds with different attributes to be combined to generate crossbred progeny tailored to production environments and customer preferences.

    Interpretive Summary: Effects of management strategies during early lactation and weaning on etiological agents of ovine subclinical mastitis and antimicrobial susceptibility of milk-derived bacterial isolates


    TS, ewe, 100 x 100
    The objectives of this study were to quantify the prevalence of subclinical mastitis, evaluate the impact of bedding treatments on subclinical mastitis, evaluate the efficacy of weaning treatments, and identify levels of antimicrobial resistance in milk-derived bacteria.

    Interpretive Summary: Evaluation of lipid sources and emulsifier addition on fat digestion of yellow-feathered broilers


    TS, yellow broiler, 100 x 100
    Considering that commercial diets generally contain 3% to 8% added lipids to provide up to 20% metabolizable energy (ME) in broiler diets, the addition of emulsifier in diets was believed to improve the digestibility of fat.

    Interpretive Summary: Effects of dietary vitamin E and fat supplementation in growing-finishing swine fed to a heavy slaughter weight of 150 kg: II. Tissue fatty acid profile, vitamin E concentrations, and antioxidant capacity of plasma and tissue


    TS, finishing pig, 100 x 100
    The study evaluated vitamin E (VE) supplementation and fat source on fatty acid (FA) composition and VE concentrations in pigs. Three fat sources with distinctive fatty acid profiles were used; VE levels were 11 (the requirement estimate) and 200 (a high level to assure any responses could be seen) ppm.

    Interpretive Summary: Effect of limestone solubility on mineral digestibility and bone ash in nursery pigs fed diets containing graded level of inorganic phosphorus or increasing dose of a novel consensus bacterial 6-phytase variant


    TS, nursery pig, 100 x 100 (1)
    Microbial phytase is added to commercial pig diets to increase phosphorus (P) availability and reduce P excretion. It is known that an excess of calcium (Ca), mostly sourced from limestone, can affect phytase efficacy.

    Interpretive Summary: Evaluation of essential fatty acids in lactating sow diets on sow reproductive performance, colostrum and milk composition, and piglet survivability


    TS, nursing pig, 100 x 100
    Supplemental fat sources are an effective and widely accepted strategy to increase energy density of sow lactation diets that can also provide essential fatty acids such as linoleic acid (LA) and α-linolenic acid (ALA). Currently, the effects of supplemental LA and ALA provided shortly before farrowing on colostrum and milk composition are not fully understood.

    TS, preg cow, 100 x 100
    The livelihood of a cow-calf producer relies on reproductively sound cattle that give birth to live offspring once a year. Two factors, pregnancy rate and pregnancy loss, are informative measures of fertility.

    Interpretive Summary: Effects of yeast-based pre- and probiotics in lactation diets of sows on litter performance and antimicrobial resistance of fecal Escherichia coli of sows


    TS, sow eating, 100 x 100
    Feeding sows live yeast and yeast extracts from day 110 of gestation through lactation tended to increase lactation feed intake but did not affect any other sow or litter performance criteria.

    Interpretive Summary: Influence of yeast-based pre- and probiotics in lactation and nursery diets on nursery pig performance and antimicrobial resistance of fecal Escherichia coli


    TS, nursery pig, 100 x 100
    Feeding sows a diet containing live yeast and yeast extract from day 110 of gestation through weaning resulted in progeny that were heavier at weaning and had increased average daily gain and average daily feed intake throughout the nursery period.

    Interpretive Summary: Potential effect of two Bacillus probiotic strains on performance and fecal microbiota of breeding sows and their piglets


    TS, breeding pig, 100 x 100
    The aim of the present study was to determine if the inclusion of probiotic microorganisms in the mother’s diet during gestation and the lactation period is capable of modifying the performance of mothers and piglets and the possible effect on the intestinal health of piglets after separation from the mother.
