The effect of injections vitamins A, E, D3 supplemented with omega3 and vitamins A, E, D3 (without omega -3) on the growth performance and some physiological characteristics of local Iraqi female lambs

Abstract

In the animal field belonging to the animal production department/ faculty of Agriculture / University of Anbar/ Ramadi, this experiment was conducted from the fifteenth of December/ 2021 to the fifteenth of February/ 2022. In this experiment, twelve female Iraqi Awassi lambs with an average body weight of 16.737 kg and ages ranging from 90±7 days were used. Three groups, each with four lambs, were randomly selected from among the experimental animals. As the control group, the first group (T1) had not acquired any treatment at all. The second group (T2) acquired intramuscular injections of vitamins A, D3, and E of 1.5 ml supported with omega-3 of 1.5 ml and the 3rd group (T3) acquired intramuscular injections of the same vitamins, six times with a fifteen-day gap between each injection. The animals were nourished on concentrated diet consisting of 1.5% BW (mixture of barley grains and wheat bran) water, minerals bloke supplement, and alfalfa hay had given adliptum. The result of the experiment showed that T2 had significantly increased (P≤0.05) compared with T1 in the second period (p2) in an average life body weight. T2 was significantly superior (P≤0.01) compared with T1 and T3 at p2 in chest girth, estrogen hormone and white blood cell (WBC), while T2 was significantly superior (P≤0.05) compared with T1 in red blood cell (RBC) at third period (P3), whilst T1 and T2 had significantly superior (P≤0.01) as compared with T3 at P2 in haemoglobin concentration.
