Effect of cross-fostering on transfer of maternal immunity to Mycoplasma hyopneumoniae to piglets

The aim of this study was to assess the effect of cross-fostering on transfer of maternal Mycoplasma hyopneumoniae-specific humoral and cell-mediated immunity (CMI) from gilts to piglets.

Abstract

Vulvar skin temperature changes significantly during estrus in swine as determined by digital infrared thermography

This study demonstrated that VST of sows and gilts, measured by IRT, changes significantly during estrus. The potential to use digital infrared thermography as an adjunct tool during estrus detection in swine appears to be promising.

Individual sow housing benefits the animals - and people

A hog farmer from Friend, Neb., explains why sows are housed individually and how that individual care benefits the animals, helps maintain herd health and ultimately provides quality pork.

The metabolic availability of threonine in common feedstuffs fed to adult sows is higher than published ileal digestibility estimates

Using ileal digestibility values determined in growing pigs to formulate sow diets may lead to overfeeding of sows with protein and can negatively affect overall production efficiency through increased cost and excess nitrogen excretion.

Analysis of water, feed intake and performance of lactating sows

An enhanced feed and water intake during lactation may increase weaning weight of piglets and decreases relative body weight loss of sows.

Interaction of zearalenone and soybean isoflavone on the development of reproductive organs, reproductive hormones and estrogen receptor expression in prepubertal gilt

The aim of the present study was to investigate the interactive effect of zearalenone (ZEA) and soybean isoflavone (ISO) on the development of reproductive organs, reproductive hormones and estrogen receptor expression in prepubertal gilts.

United Kingdom - Sow numbers set to fall through 2011

The size of the British pig breeding herd may slip below 418,000 sows (from 2007's 436,000 sows), causing pig producers to face a further period of negative margins, according to market analysts at the latest Outlook conference of the Agricultural and Horticultural Development Board.

Task organization: What day of the week should we wean? Several weanings per week

On large farms, it is common to wean more than once per week. This way, tasks can be homogenized throughout the week: each day will have a similar volume of work as the previous day.

Abstract

Effect of N,N-dimethylglycine supplementation in parturition feed for sows on metabolism, nutrient digestibility and reproductive performance

The current pilot study assessed the influence of N,N-dimethylglycine (DMG) on insulin sensitivity, glucose and fat metabolism, nutrient digestibility and reproductive performance of sows in the peripartal period.
