Abstract

This study has been accomplished in Grdarasha fields, College of Agricultural Engineering Sciences, Salahadin University, Erbil. Kurdistan Region, Iraq. The goal was to investigate the effect of using broccoli leaves and stems instead of green fodder in different proportions (2, 4 and 6) kg/day per treatment respectively on quantity of milk production and its composition in Frisian cross bread in Erbil Governorate. With concentrated ration that includes (barley, soya bean meal and wheat bran). A total 3 cows were used in this research. PROC GLM (General Linear Model) procedure in SAS (2004) was used to analyze the data for milk production and compositions. The cows were divided in to 3 groups, each group of 1 cow, and each cow given same concentrate ration. Barley straw was given to the cow’s ad libtum, the experiment lasted 9 weeks divided into 3 periods (3 weeks each). 1st and 2nd weeks were considered introductory stages, 3rd week was an experimental stage where the produced milk was measured daily (morning and evening). Milk samples were taken from each cow in the last 2 continuous days of the experimental stage for chemical analysis. Cows ate similar amounts of dry matter, with all treatments. Results indicated the following: 1- There is a significant differences (p≤0.05) among treatments in average daily milk production that was 10.817, 11.103, 10.202 kg/day for the 1st, 2nd& 3rd treatments respectively. 2- As for milk composition, result showed significant increase (p≤0.05) in fat% for 1st treatment if compared with 3rd. Result of this research showed significant milk protein% in 2nd treatment if we compared with 3rd treatment. Results indicated that were a significant increase in daily milk lactose between 3rd treatment if we compared with 1st and 2nd treatments. The results also showed significant differences between 3rd and 2nd treatments in S.N.F.
