Analysis of reproduction and production parameters of mother populations and genealogical boar populations by means of M BLUP-AM method in Slovakia

This paper evaluates all population averages of mother population concerning both reproduction and production parameters in Slovakia during the years 1996 - 2001. The prediction of breeding value of the best boar populations WI, WM and L during the period 2000 - 2002 was carried out by means of M BLUP-AM method. Based on the achieved total population averages, the best breeds in regard to reproduction efficiency were WI and WM in year 2001 total live born piglets WI 11,28, WM 11,34 and L 10,59; new live born WI 10,75, WM 10,78, L 10,18 reared piglets WI 9,96, WM 9,88 and L 9,68. On the basis of total breeding value (TBV), the best genealogical populations of mother breeds were evaluated and included in the "top ladder". In Slovakia the best genealogical boar populations of WI breed were as follows: Pintos with 806 total breeding value (TBV), SUNAR with 784,1 (TBV) Faber with 771.8 (TBV) total breeding value. The best results in genealogical boar populations (WM breed) were achieved in Don with 701.7 total breeding value (TBV), Rank with 636.7 (TBV) total breeding value and Norik with 614.5 (TBV) total breeding value. In Landrace the best populations were as follows Floppy with 730.6 (TBV) total breeding value (TBV), Damborek with 634.3 (TBV) and Don with 723.4 (TBV). M BLUP-AM method enables more precise evaluation of genetic value of individual animals and breeds and subsequently it provides more objective controlled selection and further breeding pig breeds.
