Question

A feedlot in Kansas has provided the following information:

Recently received 5,000 feeder cattle for finishing averaging 890 lb body weight

Finished feeder cattle average 1130 lb body weight

Daily DM intake is 2.8% of animal body weight (DM of feed = 88%)

Average daily gain without use of feed additive = 3.00 lb

Average daily gain with use of feed additive = 3.30 lb

(i) Calculate the average daily feed intake per animal on ‘As Fed’ basis

(ii) Calculate the number of finishing days saved with the use of feed additive

(iii) Calculate the percent increase in feed efficiency as a result of using the feed additive

Explanation / Answer

Average daily gain(ADG)-

ADG=(Ending weight – starting weight) / Days on feed

(i)- SO accordind to feed done by Kansas, average daily gain

ADG=(1130-890lbs)/1

ADG=240lbs

(ii)- No. of finishing days- 6

(iii)- percentage increased is by 20%
