Conteúdo: 	The lactation curve in cattle has been explained by the expression: Ya = An be -cm Where Yn is the average daily yield in the nth week, and A,b, and c are constants. In general, in a sample of 859 Friesian lactations recorded during 1964-65 daily yield was depressed during the winter months (18-8% in january) and stimulated during the spring (14-7% in may) to an extent which was independent of the stage of lactation. Winter calvers on the other hand tended to produce more in total lactation than spring calvers (14-5% for animals calving in november as opposed to those calving in april).
