Aaron said:Nutrition (and good fertility) is the reason for twinning. After switching our basic mineral to a high-quality chelated product, my incidence of twins went up 1000%. Used to get a single set once every five to ten years. Now in the last 6 years I get at least 1, if not multiple sets every year. Last year was one set (thankfully), 2014 was 3 or 4. Only measurable change has been the mineral.
You haven't introduced a new bull in 6 years? :shock:
We get 8-12 sets a year minimum and the only mineral we ever feed is TM salt.
