Select the reasons that farmers typically only specialize in one breed.
Bogdan [553]
Answer options are
✅Homogeneous housing -
✅Familiarity with the breed
✅Business efficiency
✅Standardized food supply
Lack of training ❌
Time demands❌
✅Personal preference

Reasons
I’m using beef cattle to determine these answers.

I chose the ✅ answers because of the following
✅ Homogenous housing. If you live in extremely cold or hot climates, you want livestock that can withstand cold temperatures for housing reasons. Hereford and Angus are hearty and survive cold temps, Brahman are warm weather cattle.

✅Being familiar with the breed makes raising that breed easier. For example if you know Angus beef cattle and not Chalais dairy cows, you won’t know the Chalais’s unique characteristics.
✅Business efficiency - having one brand or one breed in this instance will save in time, management, food supply, medicines, etc. Different breeds will require different nutrients and feed, different housing requirements, for example.
✅ Standardized food supply. Again, different breeds require different nutrients. Having just one breed will keep food supply simple.
✅ personal preference. Although this might not be a sound business practice, people tend to stick with things they know and like.
