| Vitamins are essential nutrients that affect economically important performance traits of dairy cows, including milk production, reproduction, and udder health. |
| Milk from cows treated with it is likely to contain pus from their udders since the hormone leads to mastitis, or udder infection. |
| The strong influence of Italian neo-realism is further subverted by such outlandish sights as a boy suckling at a cow's udder and Pedro hurling an egg directly at the camera. |
| Even if there's milk in the udder, the pregnancy has to have advanced sufficiently to predict foaling. |
| And like many dairy cows, she often has mastitis, a painful udder inflammation, despite receiving antibiotics between lactations. |
| But the automatic machines use lasers to find the udders, and a computer memorizes the configuration of the udder for the next milking. |
