Indigenous cattle gained much more weight by feeding fettle, and sold 3 months earlier

The owner has been bought these indigenous cows in 25.06.2013 with the average weighted 110 kg at the time for each single cows.
As you may know, normally each indigenous cattle will gain weight about 700 g per day.
After 3 month feeding them by our fettle ( the fettle that has been grown by using Arin Fertilizer ), normally the cows have to gain weight about 63 kg which means the final weight should be about 180 kg, but when we weighted them, the minimum weight for each single cow was about 250 kg which is 80 more than usual.
The owner also has been sold them 3 month earlier than the regular time.
