Effects of protein levels in lactation sow diet on protein content in internal organs

Abstract

The paper examined the effect of protein levels in the diet of lactating sows and parity on protein content in internal vital organs of sows following the end of lactation. Due to an insufficient intake of proteins from feed lactating sows engage proteins from vital internal organs in order to meet the requirements for milk production. The paper established significant differences depending on protein level in lactating sow diet on protein level and mass in the liver. The protein level and mass in the liver were higher in sows with rations with a higher protein level. The protein mass in kidneys depended on the protein level in the ration, and it increased slightly with its increase. It was established that parity has an effect on the protein level in the liver of sows.

U radu je ispitivan uticaj nivoa proteina u hrani krmača dojara i pariteta prašenja na sadržaj proteina u unutrašnjim vitalnim organima krmača posle završetka laktacije. Usled nedovoljnog unošenja proteina iz hrane, krmače dojare da bi zadovoljile potrebe za produkcijom mleka angažuju proteine iz vitalnih unutrašnjih organa. U radu su utrvrđene značajne razlike u zavisnosti od nivoa proteina u obroku krmača u laktaciji na nivo i masu proteina u jetri. Nivo i masa proteina u jetri su viši kod krmača koje dobijaju obroke sa višim nivoom proteina. Masa proteina bubrega zavisi od nivoa proteina u obroku, sa njegovim povećanjem i ona se blago povećavala. Ustanovljeno je da paritet utiče na nivo proteina u jetri krmača.
