The effects ol oils and protein coated with Ca soaps or milk production parameters were investigated in this study The effect of acidulated oil + soybean meal + Ca(OH)2 (AY) and protein coated acid oil Ca soaps (PKAYl on dry mattei intake and milk yield parameters in early lactation of dairy cows were examined There were no significant differences among groups m investigated parameters (P>0 05). Dry matter intakes were found 16 11. 15.41. 15.53, kg/day respectively in control. AY and PKAY groups. The amount ol acidulated oil + soybean meal + Ca(OH)2 and PKAY obtained from ration was lound 5.3 and 5.5 % of dry matter intake. Milk yield was found 25.16. 23.59, 23.84 kg/day respectively in control. AY and PKAY groups. In these groups, adjusted milk yield according to 3.5 % milk lal calculated 23.73, 20.83 and 22.00 kg/day. Ad|usted milk yte'd and daily milk (at yield were low because of the low milk production and milk fat similarly the milk yield and milk proiein concentration affected daily milk protein yield m negatively Milk protein concentration was found 3.18. 3.04, 3,06 %, milk lat concentration was found 3,19. 2,90. 3 14. non lat dry matter concentration ol milk was found 8.23, 8,10, 8,15. respectively in control, AY and PKAY groups. The addition ol lat to ration both free lat and Ca soap forms effected mentioned milk fractions negatively as described before. As a result, these oil sources did not affect milk production and milk parameters statistically significantly on dairy cows.
