Dairy Farm Body Weight Measurement Of Cow
Body measurement of cattle. The internal temperature of the body is similar to the temperature of the main organs such as the brain heart and viscera sellier et al 2014. In the past 30 yr however reported estimates of body weight and skeletal dimensions using various body measurements have been limited to mixed or dual purpose cattle 16 20 24. Two novel snps c1407ag and c1425cg were identified in this study which were significantly associated with the body measurement of two chinese cattle breeds qinchuan and nanyang cattle. These body type scores were developed at the university of wisconsin in the usa and are applicable to all breeds of cattle. Body measurements are important characteristics in dairy cattle as well as in beef cattle bene et al 2007. The results suggest that c1407ag and c1425cg can be used in cattle growth related traits marker assisted selection breeding.

Many of the relationships currently being used to estimate body weight may be obsolete be cause of change in breed genotypes 8 21.
The recommended point for linear height measurement is a point directly over the hips from a level surface. Patel ashwini1 patel sanjay2 gj. Body core temperature measurement in cattle. Linear body measurements of cattle before and after 20 years of selection for postweaning gain when fed two different diets. By using the advantages of 3d depth image researchers combined a thermal imaging camera and proposed a system for measuring the body shape and temperature of black cattle to complete the periodic quality assessment during the growth of cattle 16.
