Abstract
Current study was conducted on 15 Awassi lambs with an average Weight11.24±0.06kg and with average age (1 month aged) Lambs were randomly divided into three groups,(5lambs/group) 1stgroup: control, 2nd group was injected subcutaneously once every ten days with Iron and vitamin B12 (4.54mg/kg body weight and 4.54μg/kg body weight ) 3rd group lambs wereinjected subcutaneously with Iron and vitamin B12(9.09 mg /kg body weight and 9.09μg/kg body weight ) respectively. Results showed a significant increase(P≤0.05)in final weight, total gain, daily gain, body length, chest girth,fore thickness, lymphocyte % and monocyte% intreated groups with Iron and vitamin B12 compared with control group. Also results shows a significant increase(P≤0.05)for 2nd group lambs compared with control in fore height, rear height and rear thick. While there area significant decreaseIn treated groups in neutrophils % and stress index.In conclusion, iron and vitamin B12 injection to weaning lambs improve body measurements and weight and immunity
Highlights
The importance of iron is shown in it's vital role in a numbers of body functions such as oxygen transport, energy production (ATP), DNA synthesis and its important role in protecting cells from oxidation processes (Cann and Ames, 2007); (Clare, et al, 2007; Ronald, 2009 and Youssef, 2012) as well as the important course of growth (Drakesmith and prentice, 2008)
Vitamin B12 is the basis for the metabolism of all types of animals, and it is essential to strengthen ewes during pregnancy and lactation as well as developing birth to stimulate the immune system (Girard et al.,1996 and Papadopoulou et al,(2013)
Vitamin B12 deficiency leads to reduced growth rates and birth weight as well as reduces the immune system functions of the animal
Summary
The importance of iron is shown in it's vital role in a numbers of body functions such as oxygen transport, energy production (ATP), DNA synthesis and its important role in protecting cells from oxidation processes (Cann and Ames, 2007); (Clare, et al, 2007; Ronald, 2009 and Youssef, 2012) as well as the important course of growth (Drakesmith and prentice, 2008). Iron deficiency resulted reduce in immune system effectiveness towards pathogens (Hemminki, et al, 1991), leads to a decrease in the functions of white blood cells and the production of antibodies (Scott, et al, 1975). Vitamin B12 deficiency leads to reduced growth rates and birth weight as well as reduces the immune system functions of the animal. This study was designed to determine the effect of subcutaneous injections of iron and vitamin B12 on The weight and Measurements immune performance of the Awassi lambs
