Influence of the different ratio of calcium and phosphorus in the compound feeds on the productivity of growing and finishing pigs


, : Influence of the different ratio of calcium and phosphorus in the compound feeds on the productivity of growing and finishing pigs. Bulgarian Journal of Agricultural Science 8(2/3): 261-268

An experiment was carried out at the Agricultural Institute in Shumen, Bulgaria with 42 pigs divided into three groups, from weaning at 7.0-7.2 kg (at 38 days of age) to 110 kg liveweight. The digestibility coefficients of the basic nutrients of 3 pigs from groups 1 and 3 (n=6 pigs with 60-70 kg liveweight) were determined.
