Live stock : a cyclopedia for the farmer and stock owner including the breeding, care, feeding and management of horses, cattle, swine, sheep and poultry with a special department on dairying : being also a complete stock doctor : with one thousand explanatory engravings . n relation togestation and the influence of the varying times of gestation on theyoung, to refute a prevalent idea that protracted gestation producedmales. Mr. Tessier, for forty years an accurate and acute observer ofvarious animals, gives results in the case of over 575 cows, and thesesubsequently having been exi;ended to 1,131 cows the extremes were notchanged, but results as to averages are as stated below. Earl Spencer also carefully tabulated the period of gestation of 766cows, the least period being 220 days ; the mean 285 days ; and the long- THE BREEDING OF CATTLE. 653 est 313 days. He was able to rear no calf produced at an earlier periodthan 240 days. According to Tessier, a cow may carry a calf 321 daysand produce it sound; and from the fact that Tessier and Earl Spenceragree almost exactly as to the mean time of gestation, 285 days or nineand a half months may oe taken as the average time of gestation ofcows, slight variations being allowed from this for different \ USHIKE COWS. This is emphatically the ^Mutcti dairy breed. No other breed of cattle in Scotlandwill produce an equal amount of milk, butter and cheese. Six hundred gallons ofmilk per year is considered an average yield for the cows on a well-kept farm. Theircolor is generally of red and white in spots; sometimes white and black, or red orbrown. The horns are fine and twisted upward, and the face long, with a lively yetdocile expression. It is quite safe to conclude, from the results of experiments with vari-ous races of animals, that the period of gestation has no influence whateverupon the sex of the offspring, nor is it probable that the sex of the foetushas any influence upon the period of gestation.
