    Interpretive Summary: Nutrient use and methane emissions in growing beef fed different protein sources and a pasture-based diet


    Field beans and soybean meal promote better growth and nutrient utilization compared with brewers’ spent grains when fed as the main protein source for growing beef cattle. Growing beef cattle that were fed a diet consisting solely of Italian ryegrass reduced enteric methane emissions per kg of feed consumed without affecting methane intensity but also reduced their growth rate and efficiency in using dietary energy and nitrogen, compared with beef under diets including more concentrate feeds.

    Interpretive Summary: The effect of feeding order of forage and oats on metabolic and digestive responses related to gastric emptying in horses


    Horses have evolved as grazing nonruminant herbivores with a relatively small stomach and a highly specialized hindgut capable of fermenting fibrous feeds. However, domestication might have altered the feeds consumed by horses, and today conserved forages and starch-rich concentrates often make up the ration as a substitute or supplement to grazing.

    Interpretive Summary: Effect of pre-farrowing hygiene routine (sub-standard vs. optimal) and creep feeding regime (dry pelleted starter diet vs. liquid mixture of milk replacer and starter diet)...


    Litter sizes on commercial pig farms have increased in the past number of decades. To support these large litters, creep feeding suckling piglets with a dry pelleted starter diet is commonly practiced on commercial farms, but creep feed intake can be low and variable. Increasing creep feed intake should increase pre-weaning growth and better prepare pigs for weaning.

    Interpretive Summary: Identification of transcriptional regulators and signaling pathways mediating postnatal rumen growth and functional maturation in cattle


    The rumen is the largest digestive organ in adult ruminants, where feed is digested into volatile fatty acids (VFAs) and where most VFAs are absorbed and metabolized. However, ruminants are not born with a large, functional rumen. The rumen undergoes significant growth and functional changes from birth to adulthood.

    Interpretive Summary: Effects of a preweaning socialization system on piglet livability, lifetime growth performance, and subsequent sow performance


    A preweaning socialization system is described as the co-mingling of non-littermate piglets before weaning. This approach allows 2 or more unfamiliar litters to interact and socialize during the lactation period. This system involves the removal of dividers between farrowing stalls and walkways and allows piglets to freely socialize while the sow remains in her stall.
