[QUOTE="simme, post: 1716289, member: 40418"] Average daily gain will vary with forage quality, sex, any creep feeding, milk quality and quantity and growth genetics. So, difficult to decide what absolute number is acceptable or good. ADG [B]ratio [/B]might be better to compare animals raised together. Calculate the ratio of all animals of the same sex raised together and compare. You would be comparing growth related to genetic potential as well as milk from the dam. Some people look at Weight per day of age (WDA) as well which incorporates birth weight. Weaning weight ratio does the same, just sets the WDA based on 205 days of age. There are also adjustments that can be applied based on the age of the dam. A young dam or very old dam generally will raise a lighter weight calf. The adjustment for age of dam attempts to level the field due to age of dam. Also note that ADG is not a linear straight line with age. [/QUOTE]
