Biological position of viruses: Viruses lack a cytoplasmic membrane and they do not have the basic component of a cell. They can only replicate inside the host cell. Outside the host cell, they are non-living.
The yearling program was, however, more variable with a maximum profit of $356 per head compared with $206 for calf fed, and a maximum loss of $171 per head compared with $152 for the calf fed program.
The cow will eat half a ton per month, and this year the hay is going to cost at least $90 a ton. That is $225 per year for hay. Grass is cheaper. It will only cost $20 a month for the other 7 months of the year that s $140 per year for grass.As you can see, our costs are already adding up. We have $519 invested in this cow for the first year, and we don t have a calf yet.hat totals $150 per cow for labor. And of course we have to have a pickup to feed with. I m sure that $350 per month is reasonable, divided by 250 cows another $17 per cow. Vet expense: vaccinations, parasite treatment, preg testing, and the occasional ranch visit - $10/head.
