Question2. We wish to improve weaning weight (WW) in our cow herd. h2h^{2} for WW=.38W W=.38 herd mean for W W=587lbW \mathrm{~W}=587 \mathrm{lb} \% saved (males) = 1 \% saved (females) = 15 Standard deviation for WW = 23 lb Calculate: - Overall selection intensity - Response to selection - Generation interval for: - Males - Females o Overall - Generation interval - Response per year
Assume we keep our cows for 9 calf crops starting at 2 years of age and we use our bulls for 3 calf crops starting at 2 years of age.

Studdy Solution
The **overall selection intensity** is approximately 1.6201.620.
The **response to selection** is approximately 14.15 lb14.15 \text{ lb}.
The **generation interval** for males is 3.5 years3.5 \text{ years}, for females is 6.5 years6.5 \text{ years}, and the **overall generation interval** is approximately 6.35 years6.35 \text{ years}.
The **response per year** is approximately 2.23 lb/year2.23 \text{ lb/year}.
