Why do toenails thicken as we age but fingernails donât? A. With age, there is a rapid decrease in the growth rate for both toenails and fingernails, said Dr. Richard K. Scher, head of the nail section at Weill Cornell Medical College. As a result, both kinds of nail thicken, because of the piling up of nail cells, called onychocytes. Fingernails do not thicken as much, however, because the decrease in their rate of growth is much smaller. And fingernails tend to be filed and buffed much more, which thins them. Other factors that can affect the rate of thickening include long-term trauma and impaired circulation.
Western Beef follows this regimen for its own 300-cow herd. The cost of providing these minimum vaccination requirements is $15.60 per cow-calf pair. The veterinary and medicine expense calculated from WBDCâs Cost of Production benchmark study has typically been about $20.00 per cow.f you were going to treat each cow-calf pair with all the vaccines indicated below, the cost would work out to approximately $33.00 per pair.

Couple that with the cost of a technician to inseminate the cows ($6 per cow) and frozen semen from a good beef bull with a proven record of quality offspring ($18 per cow). That's $36 total per cow inseminated. At 60% to 65% conception, the AI program costs $55 to $60 per calf born â about 20% less than the bull.
