Influences of housing systems and slaughter weight on the market realization of slaughter pigs by seurop classification

Abstract

The aim of the study was to evaluate an influence of housing technology and slaughter weight of slaughter pigs on realization with SEUROP system. Slaughter pigs of hybrid combination (Czech Large White x Czech Landrace) x Duroc were studied for reasons of an experiment. Analysed were 733 pigs. Slaughter pigs fattened on deep-bedded pens reached higher slaughter weight, higher back fat thickness, higher muscle deep, higher price per 1 kg of slaughter weight in comparison with pigs on slatted floor pens, but on the contrary they reached a lower portion of lean meat. These data were determined in pigs on deep-bedded pens: 117.58 kg slaughter weight, 16.78 mm of back fat thickness, 61.30 mm of muscle deep, 55.53 % of lean meat portion and price 32.15 Kč per 1 kg of slaughter weight. These data were determined in pigs reared on slatted floor pens: 110.82 kg slaughter weight, 14.38 mm of back fat thickness, 56.67 mm of muscle deep, 57.11 % of lean meat portion and price 31.86 Kč per 1 kg of slaughter weight. A statistical conclusive difference on a level of importance P LESS-THAN OR EQUAL TO 0.01 was found between pigs bred on deep-bedded pens and on slatted floor pens in traits slaughter weight, back fat thickness, muscle deep and meatiness. From experiment it is obvious that for 1 kg of slaughter weight in all business classes SEUROP higher price was in pigs fattened on deep-bedded pens in comparison with pigs fattened on slatted floor pens.
