Influence of Boars with Different Growth Energy at Reproductive Values of Sows and Posterity Productiveness
Abstract
Usage of high growth energy boars influences piglets’ safety growth and their live weight by weanling. Descendants of boars with high growth energy (1st group) used to reach 100 kg of live weight compared to control group boars during 6,5 days (P≤0,001) at lower forage spends (at 9,6%). Descendants of boars with high growth energy have tendencies to thinner fat. Animals of 1st group have 9,1% thinner fat than those of control group. Meat of descendants of high growth energy animals contains less fat (at 1,7%, P≤0,001), more protein (at 1,6, P≤0,001). Usage of high growth energy boars in period of control growing (1000g/24h and more) let us better particular reproductive traits of sows, and fattening traits of posterity with no negative influence at meat-fat qualities and physical-chemical characteristics of meat.
