Deana Hancock's Animal Science "Family Tree" Story
ASAS has been a constant presence in my family's life, opening doors and providing opportunities for three generations. It all began with my father-in-law, Gerald Hancock, as an undergraduate student at MU, where he had the privilege of taking Dr. Preston's classes. Then, I pursued my Ph.D. at Texas Tech, also studying under Dr. Preston. And now, the legacy continues with my daughter, Sydney Schnur, who recently graduated with a degree in animal science from Purdue and completed her Ph.D. in Veterinary ImmunoPathobiology at Kansas State under the guidance of a former student of Dr. Preston, Dan Thomson, Ph.D./DVM.
ASAS has been more than just an organization to us. It has been a second family, a source of support, and a catalyst for our growth and success. I am grateful for the doors it has opened for my family and for the countless opportunities it continues to provide.

Interpretive Summary: Designing an early selection morphological traits index for reproductive efficiency in Pura Raza Española mares
Historically in livestock production, employing combinations of traits as selection criteria for indirect selection of related traits has been a challenging task, particularly when this implies selection for reproductive traits based on the animal morphology. However, if the decision about animal selection is based on morphological traits that are quick and easy to obtain, in addition to early reproductive traits, selection responses can be improved and made earlier.

Interpretive Summary: Long-stranded non-coding RNAs temporal-specific expression profiles reveal longissimus dorsi muscle development and intramuscular fat deposition in Tianzhu white yak
In-depth analysis of the molecular regulatory mechanisms involved in the development of yak skeletal muscle can aid in the identification of crucial functional genes that may enhance the quality of yak meat in the future. Our research is the first to investigate the expression of long-stranded non-coding RNAs (lncRNAs) during muscle development and intramuscular fat deposition in Tianzhu white yaks at different ages (6, 30, and 54 mo).

Interpretive Summary: Effects of the central melanocortin system on feed intake, metabolic hormones and insulin action in the sheep
Highly productive ruminants face short-term nutritional deficits during demanding phases of their life cycle. They remain productive and healthy during these periods through a series of metabolic adaptations. Current models in ruminant biology attribute the coordination of these adaptations to circulating hormones and bioactive metabolites but have not considered the possibility that the central nervous system (CNS) is also involved.

Interpretive Summary: Effect of the supplementation with a combination of plant extracts on sow and piglet performance and physiology during lactation and around weaning
Weaning is a critical period for piglets. Some plant extracts, known to exhibit antioxidant, anti-inflammatory, or antibacterial properties, may improve piglets’ robustness at weaning. This study investigated the effects of a maternal and/or a direct supplementation of piglets with a combination of plant extracts on sow and piglet metabolic, immune, inflammatory, and oxidative status during lactation and around weaning.

Interpretive Summary: Variability of sialic acids in meat from alternative species to beef and pork
High consumption of red meat is associated with increased risk of human cardiovascular diseases and cancer. However, meat is also considered important for human diet by providing intake of essential compounds.

Interpretive Summary: Evaluation of multienzyme supplementation and fiber levels on nutrient and energy digestibility of diets fed to gestating sows and growing pigs
Fiber-degrading enzymes have been extensively studied in growing pigs with minimal studies focusing on gestating sows; however, commercial gestating sow diets often contain more fiber than grower pig diets to stimulate the sensation of satiety without influencing weight gain. A challenge with dietary fiber is its hindrance on digestibility of nutrients.

Interpretive Summary: Dietary glycine supplementation improves the growth performance of 110- to 240-g (phase II) hybrid striped bass (Morone saxatilis ♀× Morone chrysops ♂) fed soybean meal-based diets
Glycine is the simplest but the most abundant amino acid in the bodies of animals including fish and pigs. The content of glycine in plant-sourced feedstuffs (e.g., soybean meal) is generally low. Glycine can be synthesized de novo in all animals and, therefore, has traditionally been classified as a nutritionally nonessential amino acid for fish and mammals.

Interpretive Summary: Influence of fiber type and carbohydrase supplementation on nutrient digestibility, energy and nitrogen balance, and physiology of sows at mid and late gestation
This study evaluated the effects and mechanisms of supplementing multicarbohydrases to gestating sow diets containing either corn-dried distiller grains or sugar beet pulp fibrous co-products. Findings revealed significant energy, dry matter, and fiber digestibility enhancements with carbohydrase supplementation, irrespective of adaptation time.

Interpretive Summary: Associations of automated body condition scores at dry-off and through early lactation with milk yield of Holstein cows
The objective of this study was to analyze the associations of body condition score (BCS) and BCS change (∆BCS) during the dry period and the first 100 d of lactation with daily milk yield. The involvement of health status in these associations was also evaluated.

Interpretive Summary: Accuracy of enteric methane emission models for cattle in sub-Saharan Africa: status quo and the way forward
Accurate estimates of enteric methane (CH4) emissions are needed to ascertain the efficacy of mitigation strategies proposed for cattle in sub-Saharan Africa (SSA). Models used for cattle in SSA were developed using data on metabolic processes measured from cattle in temperate regions which may lead to inaccurate enteric CH4 estimates.

Interpretive Summary: Low birth weight and reduced postnatal nutrition lead to cardiac dysfunction in piglets
Heart disease is the leading cause of death in humans, and in addition to the known modifiable risk factors, evidence suggests early life undernutrition increases heart disease risk in adulthood. Specifically, low birth weight (LBW) has been linked to poor infant cardiac development which could be made worse by an inadequate postnatal diet.

Interpretive Summary: Effects of hydrolyzed chicken liver on digestibility, fecal and urinary characteristics, and fecal metabolites of adult dogs
Feeding companion animals with high-protein diets has been a demand of the market and pet owners. However, the protein quality and quantity consumed can interfere with the amount of undigested protein that reaches the hindgut and be fermented. Intestinal fermentation can be desired when well controlled.

Interpretive Summary: A glucagon-like peptide-1 receptor antagonist reduces the insulin response to a glycemic meal in ponies
Horses and ponies are prone to suffer from laminitis if they produce too much insulin after eating a high-sugar/starch meal. Laminitis associated with high insulin is very painful and can result in the affected animals having to be put down. The reason why some ponies over-produce insulin is not known.
