Abstract:

This experiment was carried out at the cows Al-Khalis station in Habhab district in Diyala Governorate, during the period from 1-10/2022 to 1-5/2023 using 16 Holstein multiparous cows from milk-producing cows raised at the station. The animals were randomly divided into four treatments in the last two months of pregnancy and were as follows: T1: four cows without dosing (control treatment). T2: four cows were vaccinated 3000 IU vitamin E/cow per day. T3: three cows were tested for the nanoparticle selenium in an amount of 5 mg/cow per day. T4: five cows were spayed with a combination of vitamin E 3000 IU and nano-selenium in an amount of 5 mg/cow per day. Vitamin E is Alfa tocopherol acetate powder packed in capsules after weighing and dosed directly into the animal's mouth, as well as selenium nanoparticles packed in a capsule and dosed to cows once a day in the morning. The results showed that treatment T2 exceeded the percentage of fat in milk, reaching 5.60% compared to the other dosing treatment T3 and T4, which amounted to 2.46 and 2.82%, respectively, 10 days after birth, while there were no significant differences between the treatments in the rest of the milk components, represented by the percentage of protein, lactose sugar, ash, non-fat solids and milk density, while the degree of milk freezing there was a significant superiority of treatment T1, while treatment T4 exceeded the concentration of vitamin E and selenium in milk, reaching 2.89 Ppm for vitamin E and amounted to 4.05 ppm for selenium compared to the T1 control, which recorded 0.94 and 1.98 ppm for vitamin E and selenium, respectively, and a significant increase occurred in The concentration of vitamin E in milk for the T2 treatment was recorded at 2.43 Ppm, while the T3 treatment recorded a significant increase in the concentration of selenium in milk, where it was recorded at 3.18 Ppm compared to the control treatment mentioned above, we conclude from the current study that dosing cows with vitamin E or selenium nanoparticles in previous quantities has a significant role in increasing the levels of these elements in the milk produced from cows, which increases its nutritional value.
