Pregnant pigs may be at a higher risk of poor physiological outcomes due to heat exposure compared to mature female pigs that are not pregnant. The purpose of this study was to evaluate the stress response of pregnant pigs to increasing environmental temperatures using heart rate variability, a noninvasive measure commonly used to evaluate the physiological stress response.

Castration is a routine procedure performed on beef and dairy operations in the United States. All methods of castration cause pain. The American Veterinary Medical Association and the American Association of Bovine Practitioners recommend that anesthesia and analgesia be administered during castration.

Understanding the swine female reproductive system is important for solving issues related to reproductive failure and litter size. The oviduct is the site of fertilization. After fertilization, the fertilized egg moves to the uterus for implantation.

Acidosis in feedlot cattle is common, especially during the transition period from high forage to a grain-heavy diet. Nutritionists are consistently looking for alternatives to mitigate the adverse effects associated with this transition.

Bovine respiratory disease (BRD) is the cause of 60- to 90% of morbidity and mortality cases in feedlot cattle. Suppose factors associated with an animal first identified with BRD that is also associated with increased mortality risk could be identified.

This experiment aims to investigate an antimicrobial blend consisting of essential oils, medium-chain fatty acids, and a toxin-adsorbing mineral on diarrhea, growth performance, and gut microbiome of newly weaned pigs experimentally infected with a pathogenic Escherichia coli (F18 E. coli).

With consumers wanting less antibiotic usage in cattle production, the need for natural feed ingredients that have positive effects on animal health are needed.

In today’s production settings, ruminants are provided monotonous feeding environments that do not allow the animals to make feed choices. The objective of the current study was to provide a varied diet of fresh forages (perennial ryegrass, plantain, alfalfa, and chicory) over the day.

Bovine respiratory disease (BRD) is the most economically significant disease for cattle producers in the United States, affecting 16.2% of cattle on feed.

The current study's authors aimed to determine a time-series effect of phytase on phosphorus (P) utilization in growing and finishing pigs. Growth performance, apparent total tract digestibility (ATTD) of nutrients, P excretion, and plasma concentrations of minerals were evaluated during two experiments.

Tryptophan is often a limiting amino acid in corn-soybean meal-based diets of pigs and plays a vital role in appetite regulation. However, this mechanism competes with other large neutral AA such as Val, Leu Ile, Tyr, and Phe. Standard corn and sorghum diets fed to pigs are rich in Leu and may reduce pig feed intake and growth performance.

Drylots are becoming a more common method of managing cow/calf pairs because they provide more flexibility for nutritional management, calving monitoring and provide shelter from wind and rain to decrease maintenance nutrition requirements in the winter. However, limited work has focused on the impact of dry-lot cow/calf management on cow/calf behavior and performance around the time of weaning.

Managing low protein diets in pigs is challenging because reduced dietary protein frequently leads to impaired growth performance and increased intramuscular fat. Supplementation with essential amino acids (particularly lysine, tryptophan, threonine, and methionine) is helpful, however may not fully ameliorate the negative impacts of a low protein diet.

Longer reproductive lives are highly sought after in sows because it increases the profitability of commercial farms. Sows that reach their fourth parity and produce large litters are highly desired.

Intrauterine growth restriction (IUGR) caused by placental insufficiency is highly problematic because fetal hypoxemia leads to low birthweight and impaired growth in livestock. Ways to counter the negative impacts of placental insufficiency are therefore necessary to increase the productivity and health of IUGR-born livestock.

Silymarin is a flavonolignan extracted from milk thistle fruit and seeds. It has traditionally been used to reduce liver inflammation and toxicity in both humans and animals but may also potentially increase milk production during lactation.

Dietary spray-dried plasma protein (SDPP) is widely used in nursery pig diet due to its high nutrient contents and growth-promoting effects. In the present work, two sources of SDPP were evaluated for energy and amino acid (AA) digestibility and growth performance in nursery pigs.

Promising research is being performed at the Institute for Global Food Security (IGFS) at Queen’s University Belfast, feeding seaweed to farm animals. The technique is said to reduce methane by at least 30%.

NCBA agrees that the labeling of these products is important. Danielle Beck, Senior Executive Director of Government Affairs, noted a survey where 74% of consumers agreed that there should be a clear indication of whether the meat, they are purchasing is either lab-grown or conventionally produced.

The Food and Agriculture Organization of the United Nations (FAO) recently published The State of Food and Agriculture 2021. The report comes after the COVID-19 pandemic showed vulnerability within the agrifood system globally.
