Pigs breeding in welfare
1998
Paska, I. (Slovenska Polnohospodarska Univ., Nitra (Slovak Republic))
Pig reproduction and performance and piglet behaviour for 87 days after birth were tested within the biological programme at a reconstructed farm for pig breeding where technical and technological adaptations were made, meeting the natural requirements of animals. The central element to the research were newly constructed KNOP-1 pens whose equipment and overall design met the basic requirements of animals for comfort. The research work was methodologically directed by the Department of Animal Husbandry of the Slovak Agricultural University in Nitra (Slovak Republic). The obtained 5-year results were statistically evaluated by variation and statistical methods, and some differences were verified by t-test. Higher productivity per sow per year, i.e. 2-4 pigs in purebread BU breeds, and an increase by 3-5 piglets after crossbreeding with meat type boars were found in KNOP-1 pens than in AGRA pens. Gradual piglet weaning proved to be better: after weaning, piglets did not change their daily routines. The feed consumption in hybrids after termination of rearing was satisfactory, net muscle ratio (EUROP) was 53.25 or 55.39% at pH 1, 6.6 or 6.5, cholesterol content was 60.01 or 58.18 mg in 100 g meat, and protein ratio was 21.72 or 22.14%
