Calfat - Increased milk production: Mean data across studies

Calfat provides an increased energy supply which can be efficiently converted to milk and has been proven to increase milk production in many research studies over the last 30 years.

Chalupa and Ferguson (1992) collated data from 18 research studies at Penn State University and reported an average response in milk yield of 2.3 kg/d (<0.01) when cows were supplemented with between 450 and 570 g Calfat/d.

Rabiee et al. (2012) reviewed randomized controlled trials using meta-analysis and meta-regression techniques to evaluate the effects of supplementation with fats on milk production and components by dairy cows.

The study evaluated five groups of fats : Calfat (Ca salts of palm fatty acids), other calcium salts (flaxseed, fish oil, linseed), tallow (including tallow, white grease, yellow grease), oilseeds (whole cottonseed, whole sunflower, whole soybeans, and oils derived from these) and prilled fats (saturated fatty acids).

Results from the study indicated that Calfat increased milk yield by +1.55 kg/d, a higher response than any of the other oil sources assessed. Similarly, Calfat increased milk fat concentration by +0.099 %, and milk fat yield by +0.082 kg/d.
