For raising of dairy replacement heifers, use husbandry standards for veal calves. Facilities must not be overcrowded. Prolonged housing of cows in stanchion or tie stalls is not permitted. Hormones to increase milk production are prohibited. Withdrawal periods for intramammary medications are twelve days, or twice the label specification, whichever is longer.
Treated cows are to be milked at the end of the string.
B. Laying Hens 1. The keeping of hens in battery cage operations is not permitted. Whatever housing system is used, the stocking density should be no greater than 2.0 square feet per bird. More space may be needed in flocks producing fertile eggs or when using more aggressive breeds. The basic behavioral needs of hens to move, scratch, flap their wings, preen and nest must be respected and space provided so these activities can occur.
