    Interpretive Summary: Effects of Aspergillus oryzae prebiotic on animal performance, nutrients digestibility, and feeding behavior of backgrounding beef heifers fed with either a sorghum silage- or a byproducts-based diet


    100x100 ASAS Blog Template - 2023-03-22T121824.532
    This experiment evaluated the effects of the dietary inclusion or not of Aspergillus oryzae prebiotic (AOP; 2 g/d) in two contrasting diets: sorghum silage-based (SS) vs. byproducts-based (BP), on growth performance, nutrient digestibility, and feeding behavior of growing heifers.

    Interpretive Summary: Feeding a Saccharomyces cerevisiae fermentation product before and during a feed restriction challenge on milk production, plasma biomarkers, and immune function in Holstein cows

    Postbiotic fermentation products have the potential to improve health and support anti-inflammatory functions when fed to lactating dairy cows. Since dairy cows experience disruptions of the intestinal barrier function at various stages of their life, for example, the transition into lactation, we sought to investigate potential beneficial effects of feeding a Saccharomyces cerevisiae fermentation (NTK) before and during a period of feed restriction to challenge gut function.

    Swine can be exposed to a variety of nutritional stressors that can affect their well-being and productivity. Three stressors of concern include grains with naturally occurring mycotoxins, oxidized proteins in feedstuffs due to overheating during processing, or lipids that have been damaged by excessive heating.

    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 fecal characteristics and oxidative stress of dogs undergoing transport stress.

    Interpretive Summary: Performance and milk fatty acid profile of beef cows with a different energy status with short nutrient restriction and refeeding


    100x100 ASAS Blog Template - 2023-03-16T100348.554
    Lactating cows can undergo periods with a negative energy balance due to feed shortages, which trigger metabolic adaptations to support cow maintenance and milk yield. We explored beef cows’ response to a short feed restriction (4 d, 55% of their energy and protein requirements) and subsequent refeeding (4 d, 100% of their energy and protein requirements) in the second month of lactation.

    Interpretive Summary: Effects of replacing inorganic salts of trace minerals with organic trace minerals in the pre- and postpartum diets on mineral status, antioxidant biomarkers, and health of dairy cows


    100x100 ASAS Blog Template - 2023-03-16T122044.118
    Trace minerals (TM) are important for oxidative balance and immunity of cows. Different forms of TM are available for dietary supplementation of dairy cows. We tested whether replacing inorganic salts of TM by organic sources of TM in both pre- and postpartum diets improve TM concentration in body fluids and liver, antioxidant capacity in blood, and postpartum health of dairy cows.

    100x100 ASAS Blog Template - 2023-03-16T124855.383
    Net energy (NE) is the most refined energy system in animal nutrition, and understanding the NE partition patterns of pigs can help us to develop suitable feeding strategies to improve the growth performance and carcass traits of pigs. However, it is time-consuming, laborious, and expensive to directly measure the NE; thus, establishing a predicted model is more efficient.

    Interpretive Summary: Impact of ileal indigestible protein on fecal nitrogen excretion and fecal microbiota may be greater compared with total protein concentration of diets in growing pigs


    100x100 ASAS Blog Template - 2023-03-16T125731.350
    Dietary protein concentration has been gradually reduced because reductions in protein concentration in swine diets are known to be beneficial in terms of feed costs, nitrogen excretion, and intestinal microbiota. However, ileal indigestible protein concentration may be more influential in those variables of pigs compared with total protein concentration in diets because ileal indigestible protein considers both protein concentration and digestibility of diets.
