In the past, almost all the meat from these herds was consumed domestically.
And I have to agree that seeing these herds, once slaughterhouse-bound, roaming Nevada prairies is a heart-stirring sight.
For example, grass-fed cattle have been shown to produce more nutritionally rich milk, but these herds may be organic or conventional.
These herds were hunted by tribes of nomadic Indians and plundered for their meat and hide by freewheeling horsemen of Spanish descent called gauchos.
And as these herds have foraged farther afield for food, they have strayed into roads, farmland and subdivisions and run afoul of their neighbors.
These herds had a higher milk yield but lower solid content.
The most commonly used antimicrobial drugs in these herds were tetracyclines, sulphonamides, and florfenicol.
We assume though, that the mortality rate among these herds must have been high as well, for the following reasons.
As calf diarrhoea appears relatively common in these herds, attention to calves with diarrhoea may not be a common practice.
Lactation levels generally range between 16% and 60% in these herds, with maximum daily yields occurring 8to1212 weeks after birth.
Within each of these herds, five cattle greater than one year of age were sampled and the same animals were sampled each year.
