Division Feeding in the context of the production of pork intended for use in the making of ‘kabanosy’

Original text. Later amendments are not shown.

Feeding refers to fatty-meat fattening. The aim is to produce pigs with a bodyweight of up to 120 kg, characterised by a higher intramuscular fat content (more than 3 %).

  • Fattening is based on late-maturing breeds, and an appropriate fattening regime makes it possible to achieve the desired intramuscular fat content. The breeds used for fattening do not carry the RN gene, and the RYR 1T gene is present in 20 % of the population.

  • Fattening should be carried out in three phases – phase I up to about 60 kg, phase II up to about 90 kg, and phase III up to 120 kg,

  • Fattening of animals up to 90 kg bodyweight is carried out using two types of feed mixes. The feed mixes (doses) contain:

    — as energy components

  • cereal middlings – wheat, barley, rye, oat, triticale or maize; maize middlings and middlings of naked oat varieties account for up to 30 % of mixes,

    • — as protein components

  • – lupin, field bean and pea middlings, post-extraction soya meal, post-extraction rapeseed meal, rapeseed oil cake, fodder yeast or dried green fodder.

  • Feed mixes (doses) for animals from 90 to 120 kg contain:

    — as energy components

  • wheat, barley, rye and triticale middlings. Maize middlings and middlings of naked oat varieties may not be used in mixes (doses),

    • — as protein components

  • middlings of leguminous crops (lupin, field bean and pea), post-extraction soya meal, rapeseed oilcake or post-extraction rapeseed meal and dried green fodder.

  • At no point in the feeding cycle may the following be used: vegetable oils, feed of animal origin, e.g. powdered milk, dried whey or fish meal.

  • The metabolic energy content in mixes in all phases of fattening is 12-13 MJ of ME/kg of mix. The protein content in mixes should be around 16-18 % in the first phase of fattening, 15-16 % in the second phase, and about 14 % in the final phase.

  • Doses for fatteners may be based on nutritive mixes alone, or nutritive mixes and bulk feed, i.e. potatoes and green fodder.
