Резюме: The objective of the study was to test the influence of higher energy level in the compound feed on sow body development and milk yield (detected through piglets” growth rate).
During lactation period, two scientific experiments were carried out at Agricultural institute – Shumen.
The First Experiment comprised 8 primiparous sows allotted into two groups of 4 animals. The Second Experiment comprised 10 primiparous sows also allotted into two groups. The sows from the two experiments were allotted by the analog method – observing number, live weight, and lineage. Each of the two experiments was under the following scheme: group I, control– fed standard feed; and group II, experimental – standard feed supplemented with 8% Nutracore. Nutracore is protected fat, forage raw material and quality source of energy. It is a calcium salt of long-chained fatty acids. It contains palm oil fatty acids, calcium, and water.
In conclusion administration of higher energy level in the compound feeds (from 12.01-12.27 to 13.77-13.88 MJ) for lactating Danube White sows improves their milk yield, expressed by the live weight of their piglets at the 21-st day.
