The ability of ewes and their lambs to keep together during the first day or two of life, when the mother—offspring bond is consolidating, was examined in fine-wool Merino, Dorset Horn and Crossbred (Border Leicester × Merino ewes mated to a Suffo

Normal dairy cows were “stressed” by simple isolation from the herd and chasing by a dog. Quarter milk samples showed, in some instances, a marked rise in cell count, the quarters responding having, in general, a history of infection though the c

A modified Gerber fat test for the determination of fat in meat and separable fat is described. A factor of 0.935 is applied to correct for the difference between the S.G. of butterfat and body fat. Average recovery of purified animal fat was 99.9 pe

The use of a rolling ball viscometer to estimate the cell count of milk treated with California Mastitis Reagent is described. The method compares favorably with the direct microscopic count and requires relatively simple apparatus and unskilled oper

Three factors likely to influence results obtained with a viscometric technique for estimating the somatic cell content of cow's milk are examined, namely, reagent composition, mixing time after addition of reagent and “holding time” before deter
