The objective of this study was to define the coefficients for the calculation of standard milk production and the average daily milk production for the whole lactation, from the milk production measured on one test day. Individual milk production data from a farm, with an average of 45 milking cows, in the Khonkaen province, were collected daily over a period of one year. Data from healthy cows, in lactations 1 to 6, were used. The lactation period was divided into 13 separate periods: days 0-15, 16-30, and every 30-day period after that. Parity was divided into first parity and parities …

The goal of this study was to generate production indicies for evaluating cow and farm production efficiency. The milk yields from cows on 10 farms in the Khonkaen province were recorded. The data were transformed into a value depicting standard milk production and subsequently calculated to show the average standard milk production of each farm and an average for all farms. These data were used to calculate 2 production indecies: 1) a cow production index, calculated by dividing the cow standard milk production figure with the average standard milk production for the farm, and 2) a herd production index, calculated …
