Abstract

To investigate the effects of different levels of calcium salt of long- chain fatty acids (Ca-LCFA) and replacing COTTONSEED MEAL with CANOLA MEAL in dairy cow ration, an experiment was conducted with change over design (with a 2*2 factorial arrangement) including 4 rations, 4 periods of 21 days, and 8 dairy cows after calving. Treatments were including COTTONSEED MEAL or CANOLA MEAL (15% of dietary dry matter) and fat supplement (Ca- LCFA) at 3 or 6% of dietary dry matter. Results of the experiment showed that there is no interaction between fat supplement and canola or COTTONSEED MEAL. Average daily MILK PRODUCTION, milk fat percentage, Solid-Not-Fat (SNF), Dry Matter Intake (DMI) and Body Weight (BW), were not altered by inclusion of 15% CANOLA MEAL or COTTONSEED MEAL (p>0.05), but milk protein percentage increased when cows fed with CANOLA MEAL (2.86 vs. 2.81) (P<0.05). Daily MILK PRODUCTION, milk protein percentage, milk fat percentage, body weight and SNF were not affected by feeding ration with 6% Ca- LCFA (p>0.05). 6% Ca-LCFA significantly decreased dry matter intake (24.94 vs 25.25 kg/day) (p<0.05). As a result, ration with 3% Ca-LCFA and replacing COTTONSEED MEAL with CANOLA MEAL are suggested, without negative effects on MILK PRODUCTION and composition in dairy cow ration in early lactation.
