    Interpretive Summary: Effects of early intermittent maternal separation on behavior, physiological, and growth performance in piglets


    Although management methods, such as split-suckling and foster care, in pig production can improve piglet survival rates, these methods inevitably lead to neonatal maternal separation which is an early stress on the body, and can have serious negative effects on the body. In this experiment, we investigated the effect level of neonatal maternal separation on behavior, physiology, and growth performance of piglets.

    Interpretive Summary: Plasma protein levels of young healthy pigs as indicators of disease resilience


    A challenge of selection for disease resilience is that it is difficult to directly select pigs that have greater resilience to multiple diseases in the healthy nucleus herd environment which is essential for breeding programs. A possible alternative is to select an indicator trait or marker that can be measured in a healthy setting, is heritable, and is associated with the genetics of disease resilience.

    Interpretive Summary: Genetic parameters for fleece uniformity in alpacas


    The quality of alpaca fiber is mainly assessed by a low fiber diameter. However, the fiber diameter can greatly vary along the different body locations of the animal, the industry demands not only the fineness of the fiber but also the fleece uniformity.

    Interpretive Summary: Genetic parameters for mouth size and their influence on growth traits in pasture-raised Nelore cattle


    Evaluating traits that allow breeders to increase production efficiency in beef production systems is important. The mouth size (MS) score is a trait easily measured and implemented by breeders. Our results showed that MS in Nelore cattle is a heritable trait, and it is favorably associated with growth traits, indicating that animals with larger mouth are heavier at weaning and gain more weight after weaning on pasture.

    Interpretive Summary: Reproductive performance and transcriptome analysis of ovaries at different parities in female rabbits


    The pregnancy data of 658 female rabbits from the first to sixth parities (P1 to P6) under the same mating pattern were used to assess the rate of conception at different parities. The reproductive performance and follicular development of P1, P2, and P6 female rabbits were analyzed. The results showed that conception rate was dramatically reduced in P6.

    Interpretive Summary: Impact of shade in beef feedyards on performance, ear temperature, and heat stress measures


    This study was performed over two separate summers to evaluate natural exposure to heat and quantify the impact that providing shade has on stress measures, estimates of body temperature, and feedlot performance.

    Interpretive Summary: Inclusion of Berberis vulgaris leaf in the diet of fattening lambs: effects on performance, nutrient intake, rumen fermentation, and carcass traits


    Barberry (Berberis vulgaris) leaf (BVL) is an agricultural by-product rich in plant secondary compounds such as alkaloids, flavonoids, anthocyanins, and tannin. The present study was aimed to first, evaluate in vitro nutritional value of BVL and second, explore the effects of BVL inclusion in finishing lambs diet (at levels of 0%, 7.5%, and 15% dry matter [DM] of diet), in partial replacement of alfalfa hay, on performance, carcass characteristics, and ruminal fermentation.

    Interpretive Summary: Efficacy of a bacterial 6-phytase supplemented beyond traditional dose levels on jejunal mucosa-associated microbiota, ileal nutrient digestibility, bone parameters, and intestinal health, and growth performance of nursery pigs


    After weaning, pigs start to receive solid diets throughout nursery phase with high amounts of plant-based feedstuffs containing various antinutritional and allergenic compounds. Feed enzymes have been used in nursery diets to reduce or remove the negative impacts associated with these compounds.

    Interpretive Summary: Metabolizable energy and apparent total tract digestibility of energy and nutrients differ among samples of sunflower meal and sunflower expellers fed to growing pigs


    Global oilseed production has been increasing due to the increased demand for oil as well as the increased demand for amino acids for livestock feeding. In addition to providing amino acids, sunflower meal (SFM) and sunflower expellers (SFE) also provide energy and other nutrients to the diets.

    Interpretive Summary: Evaluation of high-protein diets differing in protein source in healthy adult dogs


    Pet food trends are constantly changing. Because consumers are often focused on dietary proteins, with ingredient sources, dietary inclusion levels, and processing methods being important, they are a popular research topic. Protein sources contain different amino acid (AA) profiles and vary in digestibility, affecting protein quality.

    Interpretive Summary: Comprehensive RNA-seq profiling to evaluate the rabbit mammary gland transcriptome after mastitis


    Mastitis is a common disease in women and farm animals, which is an infection of mammary gland tissue resulting in pain, swelling, warmth, and redness. A survey of Spain and Portugal rabbit farms shows that the prevalence of mastitis was 4% in lactating does.

    Interpretive Summary: Comparison of an advanced automated ultrasonic scanner (AutoFom III) and a handheld optical probe (Destron PG-100) to determine lean yield in pork carcasses


    Pork grading is a producer-feedback system that provides carcass trait information (i.e., carcass weight, fat/lean deposition) to determine the economic value of carcasses. Packing plants generally emphasize the optimization of carcass weight and leanness by providing premium or discounted prices using a grid system. Packing plants routinely collect carcass weights while carcass leanness can be more challenging to capture.

    Supreme Court upholds Prop 12


    The United States Supreme Court has rejected an appeal by the National Pork Producers Council (NPPC) and the American Farm Bureau Federation (AFBF) that challenges California’s Proposition 12 (Prop 12). Prop 12 passed in 201 and requires pork meat sold in the state to come from pigs born to a sow housed in at least a 24-square-foot-pen. The Supreme Court’s ruling is a major blow to pork producers across the country.

    The PRIME Act is introduced, but draws criticism from meat groups


    United States House of Representatives Chellie Pingree (D-ME) and Thomas Massie (R-KY) reintroduced the Processing Revival and Intrastate Meat Exemption (PRIME) Act to make it easier for small farms and ranches to serve consumers. The bipartisan act would give individual states the freedom to permit intrastate distribution of custom-slaughtered meat such as beef, pork, or lamb to consumers, restaurants, hotels, boarding houses, and grocery stores.
