The objectives of this study were to quantify the prevalence of subclinical mastitis, evaluate the impact of bedding treatments on subclinical mastitis, evaluate the efficacy of weaning treatments, and identify levels of antimicrobial resistance in milk-derived bacteria.

Considering that commercial diets generally contain 3% to 8% added lipids to provide up to 20% metabolizable energy (ME) in broiler diets, the addition of emulsifier in diets was believed to improve the digestibility of fat.

The study evaluated vitamin E (VE) supplementation and fat source on fatty acid (FA) composition and VE concentrations in pigs. Three fat sources with distinctive fatty acid profiles were used; VE levels were 11 (the requirement estimate) and 200 (a high level to assure any responses could be seen) ppm.

Microbial phytase is added to commercial pig diets to increase phosphorus (P) availability and reduce P excretion. It is known that an excess of calcium (Ca), mostly sourced from limestone, can affect phytase efficacy.

Supplemental fat sources are an effective and widely accepted strategy to increase energy density of sow lactation diets that can also provide essential fatty acids such as linoleic acid (LA) and α-linolenic acid (ALA). Currently, the effects of supplemental LA and ALA provided shortly before farrowing on colostrum and milk composition are not fully understood.

The livelihood of a cow-calf producer relies on reproductively sound cattle that give birth to live offspring once a year. Two factors, pregnancy rate and pregnancy loss, are informative measures of fertility.

Collecting detailed measurements of animals through cameras has become an important focus with the rising demand for meat production in the swine industry.

Feeding sows live yeast and yeast extracts from day 110 of gestation through lactation tended to increase lactation feed intake but did not affect any other sow or litter performance criteria.

Feeding sows a diet containing live yeast and yeast extract from day 110 of gestation through weaning resulted in progeny that were heavier at weaning and had increased average daily gain and average daily feed intake throughout the nursery period.

The aim of the present study was to determine if the inclusion of probiotic microorganisms in the mother’s diet during gestation and the lactation period is capable of modifying the performance of mothers and piglets and the possible effect on the intestinal health of piglets after separation from the mother.

The study assessed effects of cereal grains varying in fermentable carbohydrates on non-phytate-P and phytate-P. Phytate is the major binding form of P in plant seed and is incompletely degraded.

This experiment evaluated the effects of dietary inclusion of hempseed cake in comparison with dried corn distillers grains plus solubles (DDGS) on growth performance, feeding behavior, carcass characteristics, and blood parameters in finishing heifers.

Grain processing has been used for decades to improve digestibility of finishing cattle diets, leading to improved growth performance and feed efficiency.

Given the growing concern regarding nutrition during gestation, the present study was designed to investigate the effects of energy on the reproductive performance and lipid metabolism of primiparous sows.

Gestational health challenges may influence growth performance and immunity of offspring pigs during postnatal life. In particular, porcine reproductive and respiratory syndrome virus (PRRSV) is endemic in the U.S. herd, but its effects on surviving offspring pigs are largely unknown.

Growing cattle are oftentimes provided supplemental concentrate as a source of protein and energy in order to meet performance goals when consuming low-quality forages. The effects of supplemental concentrate on forage intake vary, which may be related to the quality of forage and the characteristics of the supplement being evaluated.

Too little or too much food during gestation can lead to poor growth and health of the resulting offspring. The placenta is an important source of nutrient supply for the fetus and poor maternal diet can impair placenta growth and function.

Androgen steroid hormones, normally present in the male, but produced in excess in the female, can result in inflammation and dysfunction of tissues, which, in turn, can lead to ovulatory dysfunction.

The livelihood of a cow-calf producer relies on reproductively sound cattle that give birth to live offspring once a year. Two factors, pregnancy rate and pregnancy loss, are informative measures of fertility.

A single 400 mg dose of MPA given to reindeer bulls just before the onset of rut eliminates aggressive behavior and suppresses androgen concentrations without dramatic differences in the gross or histological structure of the testes within the first 30 d of treatment.
