Factors of rational utilization of protein in pig fatteners nutrition

Abstract

Proteins are limited and expensive nutrient in pig nutrition. Rational utilization of protein is a precondition of a high, quality and economical pig production. A lot of factor influence on protein uti­lization, while biological value is, for sure, on the first place, then protein digestibility, presence of antinutritional factors, exact adjustment of level, quality and animals requirements, and ratio between energy, lysine and nutrition management. In our production environment all mentioned above are reasons to accept synthetic amino acids to enable rational utilization of existing protein sources and to improve carcass quality. .

Proteini su skupa i deficitarna komponenta obroka svinja u tovu. Racionalno korišćenje proteina je preduslov visoke, kvalitetne i ekonomične proizvodnje svinja. Mnogo činilaca utiče na njihovo efikasno iskorištavanje a najvažniji su biološka vrednost, svarljivost, prisustvo antinutritivnih materija, precizna usaglašenost nivoa, kvaliteta i potreba životinja, odnos energije i Užina i sistem ishrane. Zbog iznetog upotreba sintetičkih aminokiselina, u našim uslovima proizvodnje, mora biti prihvaćena jer će to omogućiti efikasnije korišćenje postojećih proteinskih hraniva, uz poveća­nje kvaliteta trupa svinja. .
