APOSTOLOV, A., S. SLANEV and R. NEDEVA, 2006. Comparative investigation on the production of two-bred hybrid pigs. Bulg. J. Agric. Sci., 12: 581-586
A scientific and economic trial was carried out comprising the following two-bred combinations: group I - female Danube White x male English Landrace (DW x EL) and group II - female Landrace x male Danube White (L x DW), raised at the Experimental Base of the Agricultural Institute. During the growing period the animals were raised and fed in groups of 6 in pen and 18 animals of each combination were controlled. During the fattening period the animals were raised in individual pens, by 15 pigs of each combination. It was established that the animals from the hybrid combinations were characterized by good production traits during both periods. The pigs from the combination Danube White x English Landrace (DW x EL) compared to those from the combination Landrace - synthetic line x Danube White (L x DW) showed retarded growth during the growing period, whereas during the fattening period the same animals realized significantly higher average daily gain - 0.767 kg (P < 0.01) and better feed utilization - 3.975 kg/kg (P < 0.05) respectively.
