    Interpretive Summary: How copper can impact pig growth: comparing the effect of copper sulfate and monovalent copper oxide on oxidative status, inflammation, gene abundance, and microbial modulation as potential mechanisms of action


    100x100 ASAS Blog Template (53)
    Copper is a nonrenewable mineral resource that is essential for all biological organisms. After banning the antibiotics, copper has received considerable attention due to its antimicrobial properties that improve performance in animals when fed over the minimum requirement.

    Interpretive Summary: Acute stress deteriorates breast meat quality of Ross 308 broiler chickens by inducing redox imbalance and mitochondrial dysfunction


    100x100 ASAS Blog Template-7
    Preslaughter acute stress can cause physiological and metabolic disorders of broilers and lead to deterioration of meat quality and high incidence of pale, soft, and exudative (PSE)-like meat, which block the development of broiler industry. Acute stress-induced imbalance of redox status and insufficient energy supply are important reasons for meat quality reduction.

    Interpretive Summary: Weak genotype x environment interaction suggests that measuring scrotal circumference at 12 and 18 mo of age is helpful to select precocious Brahman cattle


    100x100 ASAS Blog Template-3
    Beef production systems rely on efficient cow-calf operations, that is, farms where the cow herd has a high level of fertility and pregnancies are common. Bull fertility also plays an important role in terms of pregnancy rates.

    Interpretive Summary: Genetic architecture of a composite beef cattle population


    100x100 ASAS Blog Template-2
    Composite breeds are commonly used in the U.S. beef industry since they provide producers with benefits such as breed complementarity and retained heterosis. However, cattle composite genomes are not well characterized.

    Interpretive Summary: Correcting for base-population differences and unknown parent groups in single-step genomic predictions of Norwegian Red cattle


    100x100 ASAS Blog Template
    Our study dealt with strategies on how to reduce biases (inflation and level-bias) and improve a parameter related to accuracy (stability) of genomic predictions of breeding values that combine genotyped and non-genotyped animals, which are denoted as single-step genomic predictions.

    Interpretive Summary: Feeding a high-energy finishing diet upon arrival to high-risk feedlot calves: effects on health, performance, ruminal pH, rumination, serum metabolites, and carcass traits


    100x100 ASAS Blog Template-4
    When high-risk cattle arrive at the feedlot, they have low feed consumption and a greater risk for disease because of stress, inflammation, and exposure to pathogens. Because of reduced feed consumption, newly arrived cattle may not be able to meet their energy requirement for growth during the first several weeks after feedlot arrival.

    Interpretive Summary: Precision feeding of lactating sows: implementation and evaluation of a decision support system in farm conditions


    100x100 ASAS Blog Template-6
    In lactating sows, nutrient requirements among individual animals vary greatly. With a single diet, lactating sows are likely to be either underfed, which results in body reserve mobilization, or overfed, which results in nutrient excretion.

    Interpretive Summary: A preliminary exploration of the impact of experiential learning on animal science undergraduates’ perceptions of humane stunning and slaughter


    100x100 ASAS Blog Template (52)
    It is essential to educate students about humane slaughter as it is a critical component of livestock production, particularly for animal science students who represent future stakeholders in agriculture. There is limited research about the effects of experiential learning on student comfort in participating in education regarding sensitive, yet important topics in the animal sciences.

    Interpretive Summary: Frequency of maternal supplementation of energy and protein during late gestation modulates preweaning growth of their beef offspring


    100x100 ASAS Blog Template (50)
    Decreasing the frequency of protein and energy supplementation to beef cattle is often used to reduce labor and feeding costs. We hypothesized that reducing the frequency of protein and energy during third trimester of gestation of beef cows would not impact maternal performance but would be detrimental to offspring growth.

    Interpretive Summary: Effects of adding potassium bicarbonate to diets with high or low crystalline lysine to influence dietary cation–anion difference on finishing pig growth performance


    100x100 ASAS Blog Template (51)
    Potassium, fed as potassium bicarbonate (KHCO3) in this study, is essential for swine and is a key component of numerous physiological processes such as the maintenance of electrolyte balance, neuromuscular function. Feeding high levels of chloride anions, via crystalline lysine (L-Lys HCl) has been shown to negatively impact intake and growth performance of pigs.

    Interpretive Summary: Effects of a Saccharomyces cerevisiae fermentation product-supplemented diet on circulating immune cells and oxidative stress markers of dogs


    100x100 ASAS Blog Template (48)
    Saccharomyces cerevisiae fermentation product (SCFP) is a yeast product containing bioactive fermentation metabolites, residual yeast cells, and yeast cell wall fragments. In this study, SCFP was investigated for its impacts on immune health, oxidative stress, and skin and hair coat health in dogs.

    Massachusetts delays rule banning the sale of some pork


    100x100 ASAS Blog Template-6
    A federal judge in Massachusetts has agreed to delay the enforcement of Question 3, the state law that would ban the sale of pork that comes from animals not housed according to the state’s housing standards. Massachusetts’s Question 3 requirements are like those in California’s Proposition 12, which has been challenged in a case that will be heard by the Supreme Court this term, National Pork Producers Council v. Ross.
