Резюме: Physiological experiment for nutrients’ digestibility was carried out in Agricultural institute – Shumen.
The aim of the study was investigating nutrients’ digestibility from ration in pigs of different crosses. The experiment comprised nine barrows with live weight 59-61 kg divided into three animals in each of the following origins: I group – Danube white breed, II group – ♀ Danube white х ♂ (English landrace х Pietrain), III group – ♀ Danube white х (English landrace х Pietrain) х ♂ Danish landrace. Pigs were placed in special pens in 7-days preparatory period and 7-days current period.
It was established that barrows with live weight 58.667-61.33 kg, from Danube white х (English landrace х Pietrain) are remarkable for their significantly better digestibility of minerals with 16.17% -17.44% and of the phosphorus with 13.23% -15.85%, compared with animals from Danube white х (English landrace х Pietrain) х Danish landrace and the purebred ones from Danube white breed.
