Abstract
Abstract This trial was conducted in the field of animal livestock Department in the College of Agriculture University of Baghdad from 1/7/2012 to 1/9/2012 to demonstrate, This study was conducted to investigate the effect of different levels of flaxseeds supplementation on milk yield and components. using 12 all Holstein cow in the first production season in the production phase (after 3 months of birth), divided into three groups of cows each kit contains five cows except comparison group (two cows). feed all cattle on feed standard only They differ in the proportions add flax seed crushed as the first treatment (comparison) and added 3% of dry seeds of flax for the second treatment, 6% of dry seeds of flax for the third transaction, overtook the second and third group of cows on a comparable amount of milk production after two weeks of treatment until the end of the experiment, the average amount of milk produced at the end of the eighth week of each cow 13.33 and 12.67 kg/day to second and third respectively as a comparison, the average 8.06 kgOn the moral impact results. (0.05 > p, 0.01 > p) in quantities (FAT, protein and lactose) transactions for the duration of the experiment with reduced fat milk from 3.25 to 2.37 kg/14 days between the start and end of the experiment for a comparison of the second and third treatment increased the amount of milk fat of 5.03 and 4.80 to 6.78 and 6.14 kg/14 days respectively, found differences significant (0.05 > p, 0.01 > p) between transactions in the amount of protein and lactose up amount is small starting week 3 until the end of the experiment Increased protein of 4.08 and 4.65 to 5.74 and 5.63 kg/14 days of treatment, the second and third, respectively, for the comparable treatment decreased the quantity of 3.84 to 2.93 kg/14 days between the start and end of the experiment, while the amount of lactose of 7.53 and 7.22 to 8.35 and 7.59 kg/14 on the second and third treatment fell from 5.73 to 4.30 kg/14 day treatment comparison between the beginning and end of the experiment.
