Pioneer colonizers: Bacteria that alter the chicken intestinal morphology and development of the microbiota
(Frontiers, 2023-03)Microbes commonly administered to chickens facilitate development of a beneficial microbiome that improves gut function, feed conversion and reduces pathogen colonization. Competitive exclusion products, derived from the ... -
Cellular proliferation and apoptosis in Staphylococcus aureus-infected heifer mammary glands experiencing rapid mammary gland growth
(Elsevier, 2023-04)Intramammary infections in nonlactating mammary glands are common and can occur during periods of rap-id mammary epithelial cell (MEC) accumulation, which may ultimately reduce total MEC numbers. Reduced MEC numbers, ... -
Genome-wide association analysis of hyperspectral reflectance data to dissect the genetic architecture of growth-related traits in maize under plant growth-promoting bacteria inoculation
(Wiley, 2023-04)Plant growth-promoting bacteria (PGPB) may be of use for increasing crop yield and plant resilience to biotic and abiotic stressors. Using hyperspectral reflectance data to assess growth-related traits may shed light on ... -
Sexing of cattle embryos using RNA-sequencing data or polymerase chain reaction based on a complete sequence of cattle chromosome Y
(Frontiers, 2023-04)When necessary, RNA-sequencing data or polymerase chain reaction (PCR) assays can be used to determine the presence of the chromosome Y (ChrY) in samples. This information allows for biological variation due to sexual ... -
Estimating energy utilization in laying hens: what are the best response criteria?
(Elsevier, 2023-09)An experiment was conducted to evaluate the effects of varying dietary energy on the performance and energy storage in laying hens from 36 to 52 wk of age. A total of 252 Hy-Line W-36 laying hens were housed in cages with ... -
Controlling hypothalamic DNA methylation at the Pomc promoter does not regulate weight gain during the development of obesity
(Public Library of Science, 2023-04)Obesity is a complex medical condition that is linked to various health complications such as infertility, stroke, and osteoarthritis. Understanding the neurobiology of obesity is crucial for responding to the etiology of ... -
Providing environmental enrichments can reduce subclinical spondylolisthesis prevalence without affecting performance in broiler chickens
(Public Library of Science, 2023-04)Environmental enrichment can increase the occurrence of natural behavior and improve leg health and other animal welfare outcomes in broiler chickens. This study aimed to assess the effects of three environmental enrichments, ... -
Intrinsic and Extrinsic Factors Affecting Neutral Detergent Fiber (NDF) Digestibility of Vegetative Tissues in Corn for Silage
(MDPI, 2023-07-26)Dairy farming requires forages with high neutral detergent fiber (NDF) to maximize milk production, sustain cows’ health, and ensure the economic and environmental sustainability of the dairy farm. The objectives of ... -
Inclusion of Quillaja Saponin Clarity Q Manages Growth Performance, Immune Response, and Nutrient Transport of Broilers during Subclinical Necrotic Enteritis
(MDPI, 2023-07-27)Necrotic enteritis (NE) is an intestinal disease that results in poor performance, inefficient nutrient absorption, and has a devastating economic impact on poultry production. This study evaluated the effects of a ... -
Postmortem Metabolism and Pork Quality Development Are Affected by Electrical Stimulation across Three Genetic Lines
(MDPI, 2023-08-11)Variations in postmortem metabolism in muscle impact pork quality development. Curiously, some genetic lines are more refractile to adverse pork quality development than others and may regulate energy metabolism differently. ... -
Open-Source Wearable Sensors for Behavioral Analysis of Sheep Undergoing Heat Stress
(MDPI, 2023-08-16)Heat stress (HS) negatively affects animal productivity and welfare. The usage of wearable sensors to detect behavioral changes in ruminants undergoing HS has not been well studied. This study aimed to investigate changes ... -
The Probiotic Bacillus subtilis MB40 Improves Immunity in a Porcine Model of Listeriosis
(MDPI, 2023-08-18)Probiotics for humans and direct-fed microbials for livestock are increasingly popular dietary ingredients for supporting immunity. The aim of this study was to determine the effects of dietary supplementation of Bacillus ... -
Finisher lamb growth and rumen fermentation responses to the plane of nutrition and naturally occurring coccidiosis
(Frontiers, 2023-04)The objective of the present study was to investigate the interaction of plane of nutrition and naturally occurring coccidiosis on finisher lamb growth performance, FAMACHA score, and rumen volatile fatty acid profile. The ... -
Effect of sire fecal egg count estimated breeding value on parasite resistance traits in Haemonchus contortus infected Katahdin lambs
(Elsevier, 2023-06)In the midst of anthelmintic resistance, genetic resistance to gastrointestinal nematodes (GIN) in lambs could reduce anthelmintic requirements; therefore, the fecal egg count (FEC) estimated breeding value (EBV) was ... -
Evaluation of the stress-reducing effect of trace mineral injection in beef calves
(Wiley, 2023-04)Background: Little is known about the effects of trace mineral supplementation on the stress response in beef calves. Objectives: To investigate the effect of injectable trace mineral supplementation (ITM) on the stress ... -
Physiological Conditions Leading to Maternal Subclinical Ketosis in Holstein Dairy Cows Can Impair the Offspring's Postnatal Growth and Gut Microbiome Development
(MDPI, 2023-07-19)Maternal metabolic disruptions, such as ketosis, can have adverse effects on fetal development and influence postnatal factors. Twelve Holstein calves were randomly enrolled in this study at birth and monitored until 8 ... -
Nutritional Composition and In Vitro Ruminal Digestibility of Crabgrass (Digitaria sanguinalis (L.) Scop.) in Monoculture or Interseeded with Cowpea (Vigna unguiculata (L.) Walp) and Lablab (Lablab purpureus (L.) Sweet)
(MDPI, 2023-07-14)The objective of this study was to evaluate the effects of interseeding crabgrass (CG) with two annual summer legumes on forage nutritional composition, dry matter (DM) yield, and in vitro fiber digestibility. The study ... -
Environmental Complexity and Reduced Stocking Density Promote Positive Behavioral Outcomes in Broiler Chickens
(MDPI, 2023-06-23)The objective was to evaluate the impacts of a complex environment and stocking density on Ross 708 broiler chicken behaviors. Eight pens contained either high complexity (HC) or low complexity (LC) environments, and high ... -
