| Abstract | ||
| Effect of acacia saligna and dry olive pulp (dop) on alleviating heat stress and the changes in hormonal status of growing lambs were studied. Two trials were carried out in Tigris farm animal in kut on 2011. In the first trial 18 Awassi growing lambs aged 5 months old and weighing about 31±4.5 Kg. for 2 months during spring season and subjected to mild climate. In the second trial the same growing lambs were classified to three equal groups. First group was fed the basal diet plus ad libitum rice straw and the second group was fed basal diet plus green acacia (Acacia saligna) leaves and soft twigs ad libitum, while the third group was fed basal diet plus 310 gm dry olive pulp. The second trial lasted for 3 months of summer season and subjected to heat stress. Temprteture was 25.6-32.5 in spring and 40-46 in summer season and consequently the animals were suffered from heat stress during summer season. Blood samples were taken at the end of the experimental period. Each of absolute and relative growth rate, total lipids, cholesterol, lactate dehydrogenase, sodium, potassium, calcium, Inorganic phosphorus, zinc, serum T3 and T4 hormones, progesterone and cortisol hormones showed a highly significant (p<0.01) decrease in hot climate (summer season) than in mild climate (spring season). Acacia shrubs and dry olive pulp treatments during hot summer season resulted in significant (p<0.05) improvements in absolute growth and relative rate, total lipids, cholesterol, lactate dehydrogenase and all measured minerals and hormones. In conclusion: in Iraq, we need the high beneficial plant for feed the animals by cheap coast. since hundreds rather thousands of years, the iraqi condition, environment a lot of adverse conditions affect on sheep especially or nutrition, harsh climate, housing and management condition, pollution under Iraqi environment condition are found side by side. | ||
