Quality and performance

 

Maximizing performance of pigs is one of the key activities of veterinarians. Many scientific and practical insights on how to enhance productivity and meat quality of pigs have evolved over the past years. This page provides quality and performance mangement related articles for pigs.

Ovarian cysts and their consequences on the reproductive performance of swine herds

Ovarian cysts and their consequences on the reproductive performance of swine herds

The aim of this work was to determine the incidence of ovarian cysts in the breeding herd and their consequences in the reproductive performance of the herd. Data from 1990 cyclic sows from two farms, with 0–12 parities, lactation length between 6 and 47 days and weaning-estrus interval between 0 and 32 days were evaluated by ultrasound examination for cyst incidence.
As cyst was considered an anaechoic structure with smooth and thin walls with a diameter larger than 2 cm that remained visible for at least 5 days after estrus onset. Cyst incidence... read more »

Impacts of chronic stress and social status on various physiological and performance measures in pigs of different breeds

Pigs typically experience various environmental stressors, which can negatively affect performance. Cortisol concentrations and various immune and performance measures are influenced by breed, but few data exist describing the impact of breed on stress responsiveness in pigs. read more >

Consequences of birth weight for postnatal growth performance and carcass quality in pigs as related to myogenesis

In polytocous species such as the pig there is intralitter variation in birth weight and skeletal muscle fiber number. It is commonly recognized that low birth weight in piglets correlates with decreased survival and lower postnatal growth rates. read more >

Compensatory growth response in pigs: Effects on growth performance, composition of weight gain at carcass and muscle levels, and meat quality

Restriction/realimentation feeding strategy was applied to pigs to increase the age at market weight and final ADG, modify protein and lipid deposition rates at carcass and muscle levels, and thereby improve eating quality of the pork. read more >

The behaviour, welfare, growth performance and meat quality of pigs housed in a deep-litter, large group housing system compared to a conventional confinement system

he behaviour, welfare, growth performance, and meat quality of deep-litter, large group-housed pigs were compared to pigs raised in a conventional housing system. TCastrated males were housed from 9 weeks of age in a conventional housing (15 pigs/pen; 1.0 m2/pig) or deep-litter, large group housing system (90 pigs/pen; 1.7 m2/pig). read more >

Increasing daily feeding occasions in restricted feeding strategies does not improve performance or well being of fattening pigs

The natural feeding behaviour of the pig is searching for feed by rooting activities throughout the day; self-feeding pigs randomly space their eating and drinking periods throughout the day consuming ten to twelve meals per day. Pigs in conventional fattening pig production are normally fed 2–3 times daily with the feed consumed within 15 minutes. The aim of this study was to determine if more frequent feedings could improve the performance of conventionally kept fattening pigs. read more >
