The estimation of variance components is computationally expensive under large-scale genetic evaluations due to several inversions of the coefficient matrix. Variance components are used as parameters for estimating breeding values in mixed model equations (MME).

Live yeast culture (LYC) is composed of Saccharomyces cerevisiae and its metabolites such as mannan-oligosaccharides, peptides, nucleotides, vitamins and unknown growth factors. The supplementation of LYC is expected to exert health benefits in animals; however, the responses of broiler chickens to supplemental LYC is not fully explored.

Larkspurs (Delphinium spp.) are native forbs poisonous to cattle and cost livestock producers millions of dollars in losses each year. The role mineral status may play in larkspur poisoning in cattle is unclear.

Over any summer, most feedlot steers in Australia will encounter 2 to 3 moderate heat waves lasting 5 to 6 d. The ability of these animals to adjust to the hot conditions and recovery from them is not well understood.

Cereal grains and by-products from cereal processing are extensively used in diets for pigs. These feedstuffs contain soluble fiber that makes digesta viscous in the small intestine.

This study aimed to evaluate biological water quality on Western German dairy farms, identify potential risk factors for impairment, and evaluate rapid test systems to score the hygienic status of troughs.

This study evaluated the influence of purebred Nellore and its crosses with Simmental, Angus, and Canchim slaughtered at the same age and body composition on their net energy requirement for maintenance (NEm).

Feed costs the major portion of poultry industry which is estimated to be 60% to 70%. The current study focused to add the fermented agro-industrial by product most of which were waste residues to the laying hen’s diet.

There are many ingredients utilized in dog foods that provide a source of dietary fiber. However, new ingredient sources can help to add variety to diet formulas and may provide benefits to pet food processing and animal health.

Spay surgery helps control pet populations, but increases obesity due to increased appetite, decreased metabolic rate, and decreased energy expenditure. Our objective was to evaluate the effects of high-protein, high-fiber diet (HPHF), and moderate-protein, moderate-fiber diets (MPMF) in female cats following spay surgery.

Zearalenone (ZEA), an estrogenic fusariotoxin, existing in various grains and feedstuffs, could disrupt the endocrine and reproductive systems. However, the underlying mechanisms of ZEA-induced follicular development have not been fully elucidated.

Late gestation supplementation of omega-3 fatty acids (FAs) or methionine (Met) alters the offspring’s development. However, the effect of both nutrients on the physiology and growth of the progeny has not been explored.

In this study, we compared indoor housing systems using automated and manual feeding methods and outdoor calf housing systems using manual feeding methods, to examine their effect on calf health, behavior, growth, and labor. Moving calves to their respective outdoor system commenced at approximately 18 d.

In this study, we demonstrate that the partial replacement of either fish meal or soybean meal with full-fat field cricket meal promotes growth and reduces the rate of diarrhea in weaning pigs.

Plant extracts such as tannic acid (TA) have been demonstrated as effective agents to control AFB1 contamination. The objective of this study was to evaluate the effects of Chinese gallnut TA in preventing aflatoxicosis in broilers.

In Bos taurus beef heifers, altering the timing of body weight (BW) growth pattern either reduced feed costs without decreasing reproduction or enhanced reproduction without increasing feed costs.

This study investigated the genetic and non-genetic factors associated with mtDNA CN in a beef cattle population of 2,371 animals using whole-genome sequencing at low depth.

The United States Department of Agriculture’s (USDA’s) Economic Research Service (ERS) has published the Food Price Outlook, 2022 report, using data from the February 2022 Consumer Price Index and Producer Price Index. The report found that food prices are expected to increase drastically over the next few months.

The United States Department of Agriculture’s (USDA) Agricultural Marketing Service (AMS) published the highly anticipated Origin of Livestock final rule for organic dairy. The amendment to the rule is said to increase uniformity in the origin of livestock production practice for organic dairy animals and reduce variance between the approaches taken by certifying agents.

The United States Department of Agriculture (USDA) announced additional resources to increase and expand meat and poultry processing capacities. Up to $23.6 million is available to processors for technical assistance through the Meat, Poultry Readiness Grant program (MPIRG program).
