    Interpretive Summary: Characteristics of ruminal microbiota and metabolome in Holstein cows differing in milk protein concentrations


    100x100 ASAS Blog Template-17
    This study aimed to assess the ruminal microbiome, metabolome, volatile fatty acid concentrations, and amino acid profiles of Holstein cows with different milk protein concentrations. Previous studies have reported that ruminal microbiota can affect the lactation performance of dairy cows. However, little is known about the composition and function of ruminal microbiota in dairy cows differing in milk protein concentrations.

    Interpretive Summary: Clinical and microbiological effects in high-risk beef calves administered intranasal or parenteral modified-live virus vaccines


    100x100 ASAS Blog Template-18
    Our objective was to determine the safety, efficiency, and effects on immunity and nasal shedding of respiratory pathogens for high-risk cattle administered an intranasal (IN), trivalent (infectious bovine rhinotracheitis virus [IBRV], parainfluenza-3 virus [PI3V], and bovine respiratory syncytial virus [BRSV]) respiratory vaccine with parenteral, bivalent bovine viral diarrhea virus (BVDV), or a parenteral, pentavalent (BVDV type I and II, IBRV, BRSV, and PI3V) respiratory vaccine, compared to an unvaccinated negative control.

    Interpretive Summary: A proof of principle study investigating the effects of supplemental concentrated brewer’s yeast on markers of gut permeability, inflammation, and fecal metabolites in healthy non-challenged adult sled dogs


    Untitled design-30
    This study evaluated the effects of concentrated brewer’s yeast on gut health in dogs. Nineteen Siberian Huskies and one Alaskan husky were blocked and randomly allocated to one of two groups. Treatment dogs received a yeast supplement for 10 wk, while control dogs received no supplement.

    Interpretive Summary: Evaluation of fermented corn protein and its effects in either high or low branch chain amino acid to leucine ratio diets on nursery pig performance and feed intake preference


    100x100 version-2
    Three experiments were conducted to evaluate fermented corn protein (FCP) in nursery pig diets. Fermented corn protein is produced when protein and yeast fraction syrup from ethanol production is added back to high protein dried distillers grains to further increase CP and Lys content.

    Interpretive Summary: Feeding dairy cows for improved metabolism and health


    100x100 ASAS Blog Template (1)
    The objectives of this review are to 1) provide an overview of how inflammation is related to the metabolism and nutrition of dairy cows; 2) present some nutritional approaches that can be applied to modulate the immunometabolism of dairy cows; 3) point-out the state-of-the-art and the frontiers in knowledge regarding how these nutritional approaches interact with metabolism and immune system in dairy cows.

    Interpretive Summary: Fescue toxicosis: a detrimental condition that requires a multiapproach solution


    100x100 ASAS Blog Template (80)
    Tall fescue (Schedonorus arundinaceus (Schreb.) Dumort.) is a widely used cool-season forage among beef cattle, horses, and sheep farmers worldwide. The popularity of tall fescue relies on the superlative productive characteristics, such as biomass production and nutrient quality in different climatic and edaphic conditions.

    Interpretive Summary: The impact of maturity stages on yield, quality, and nutritive value of ensiled Johnsongrass [Sorghum halepense (L.) Pers]


    100x100 ASAS Blog Template (78)
    Johnsongrass [Sorghum halepense (L.) Pers.] is a perennial warm-season grass that was originally introduced to the United States as a forage in the 1830s in South Carolina. The objective of this study was to evaluate the effect of maturity stage at harvest on herbage accumulation, ensiling characteristics, and nutritive value of Johnsongrass.

    Interpretive Summary: Digestible indispensable amino acid scores of animal and plant ingredients potentially used in dog diet formulation: how this protein quality metric is affected by ingredient characteristics and reference amino acid profile


    100x100 ASAS Blog Template (77)
    Indispensable amino acids (IAA) are nutrients a dog requires, but that the dog cannot create naturally, so must be included in their diet. A concept known as protein quality (PQ) reflects how closely the IAA profile of an ingredient comes to meeting the dogs’ requirements.

    Infographic: Immunometabolism in Livestock


    100x100 ASAS Blog Template (79)
    Inflammation is a key factor of many metabolic diseases (Davis, 2022). The field of immunometabolism is based on the interface of the immune system and metabolism, and seeks to better define the tissue-specific immunometabolic networks that coordinate adaptations to physiological challenges such as lactation or growth (Elsasser, 2022).
