The present study was conducted to evaluate the efficiency of adding Propolis to broiler feeds and the effect on some biochemical and biological parameters represented by its effect on the total bacterial count of intestinal flora as well as the antimicrobial effect on Escherichia coli, staphylococcus aureus and lactobacillus. We used 150 broiler chicks type Ross at the first day of age divided randomly into three groups each of 17 chicks with three replications, the first one is control group and the second and third group fed on feeds containing two levels of propolis 200 mg/kg and 400 mg/kg respectively. Results showed that using propolis at 400 mg/kg in the diet lead to a significant decrease in level of triglycerides which was 34.58 mg/ 100 ml accompanied by a mathematical reduction in total cholesterol and LDL levels, while there was an increase in glucose level. The highest propolis levels were effective in significant reduction in total bacterial count of intestinal flora, especially in the seventh week 4.9 log10, represented by a significant reduction in counts of staphylococcus aureus, lactobacillus and Escherichia coli 2.6, 3.6, 3.1 log10 respectively.

The aim of this study was to determine the correlation between some biometrical measurements (length and width) and some electrolytic concentration (Na +, K+ and Cl-) in sheep spleen. This study was conducted on 19 spleens of male sheep, they were imported from Syria to Sulaimani province, aged between less than 1 year to 1.5 year. The results showed that the mean values of weight were 108 gm and mean values of length and width of the spleens were 13.72 cm and 9.05 cm, respectively. Also, the mean values of Cl-, Na+ and K+ concentration were 14.17 mmol/L, 6.58 mmol/L, 32.89 mmol/L, respectively. The correlation coefficient between weight and width was (r = 0.661, P=0.002) was a higher correlation with  R2 = 0.437. Also It was (r= 0.932, P≤0.0001) between Na+ and K+ which was a high correlation, with the higher value of R2 =0.869. The results showed the negative correlation between weight and Na+, weight and K+ with (r= -0.161, P=0.509) and (r= -0.214, P=0.379), respectively. However, it showed the positive correlation between other parameters; weight, length, width , Na+, K+ and Cl-, the correlation coefficient (r= 0.421, P= 0.072) between width and Cl- was the highest correlation, and the value R2 = 0.177. In conclusion, our study shows the positive correlation between some parameters (weight, length and width) and some electrolytes concentration (Na+, K+ and Cl-) and the highest correlation between width and Cl-, however there was a negative correlation between weight and Na+ and between weight and K+ in sheep spleen.

A total of twenty-four healthy ewes aged between 2-3 years old and weighed about 35.09 kg of body weight were divided randomly into four groups (6 animals for each group). The first group included the non-treated control group, while the other three groups were subjected to various oral doses of melatonin 9 mg, 12 mg and 15 mg/head, respectively. All treatments were applied at 6 o'clock in the morning, to investigate the effect of treatment with melatonin during breeding season on reproductive performance and levels of some biochemical parameters in Arabi ewes from 1 May to 1 October 2017. Blood samples 7ml were collected after one hour of treatment and then monthly during the pregnancy months to determine the concentrations of biochemical parameters. After Postpartum, lambed ewes/lambs number, birth weight, placenta empty weight and cotyledon number were recorded. The results showed significant (P<0.05) improvement in reproductive performance (fertility percentage, twinning rate and the number of offspring) when ewes administrated melatonin at two doses (12 and 15 mg/ head). Also, melatonin administration caused significant (P<0.05) decrease in the concentrations of thyroxin, cortisol, and cholesterol. Conversely, there was a significant increase (P<0.05) in glucose concentration after 1 hour of treatment. The concentrations of thyroxin, cortisol, cholesterol, and vitamin C increased significantly (P<0.01) in early-gestation compared with mid and late-gestation, while the concentrations progesterone and glucose increased significantly (P<0.05) in mid-gestation compared with early and late-gestation. In conclusion, melatonin administration at doses 12 and 15 mg/ head improves ewe reproductive performance (fertility percentage, twinning rate and the number of born lambs). Additionally, the gestation stage has a negative effect on the concentrations of thyroxin, cholesterol and vitamin C.
