A Study on the Production Efficiency of 30 Commercial I. The Production Profile

Abstract

A produciton profile concluded from 30 commercial swine herds, using PigLIVE or PigCHAMP database, was persented. Data validation, secection rules and definitions of procuction indices were thoroughly described. Statistics on each index were expressed as arithmetic mean, medium standard deviation, range and 95% cofidence interval. The sign of sub optimum performance was obvious among the herd population in this study. On average, only 17.6 piglets were produced per sow per year while 23 piglets were expected with the maximum biological feasibility. Extensions on procedures to maximize lactation feed intake and proper culling practice may help producers to alleviate the sub optimum productivity. Research on finding the indidence, control and prevention of reproductive diseases deserve funding priotity. A fact that the number of breeding females in this study was increasing by 16.5% during 1992 indicate the changing structure of swine production uit toward intensification and speccialization.
