What is essential for developing a BLV-free herd?
Raising only BLV-negative heifers
What is the result of allowing BLV-positive heifers to enter the milking herd?
A continuous source of infection, making eradication impossible
What is the primary goal of reducing horizontal transmission in BLV-infected herds?
To achieve fewer and fewer new infections
What is the relationship between the level of priority and commitment to eradication and the speed of progress?
