The current study was aimed to investigate the influence of Vitamin A- Palmitate injection and grazing on some physiological and biochemical characters, milk yield and its compositions. Twenty eight Meriz does (2 years aged) after parturition with average body weight 22.57 ± 0.47 Kg, and were randomly assigned into 4 groups (7 does/group) treated for 3 months as following: 1st group does were reared on standard ration and injected with 0.05 ml of physiological saline i.m weekly, 2nd and 4th groups, does were reared on standard ration and injected with vitamin A- Palmitate (50000 IU/doe weekly) as well as grazing for 6 hrs. daily for the does in 4th group, 3rd group does were reared on standard ration with 6hrs grazing /daily. Results showed a significant increase in Hb and PCV in 4th group at 1st, 2nd and 3rd month of treatment. ESR significantly increased in 4th group at 3rd month of treatment, also serum glucose level increased significantly in 2nd and 4th groups at all months of the study, while serum cholesterol level decreased significantly in 4th group at 2nd and 3rd months of treatment. Triglyceride increased at 3rd month in all treatments as compared with control, total protein and albumin increased significantly in 2nd, 3rd and 4th groups at 2nd and 3rd months of treatment. A significant increase in milk yield and fat% were recorded in 2nd, 3rd and 4th treatments in most kidding weeks. Conclusion, results showed that vitamin A and grazing improved some of physiological, biochemical, body weight and milk yield in Meriz goats.

A total of 1116 records Awassi ewes and 432 of Hamdania ewes were collected and which belong animals resource department, Faculty of Agriculture and Forestry at the University of Mosul for the years 2008, 2009 and 2010 to study the effect of genetic and non-genetic factors in milk production and some of its components from birth until weaning. The results showed significant effects (p≤0.05) for the breed and highly significant effects (p≤ 0.001) for the year, mother's age, sex, and type of birth in the daily milk production. There was a highly significant effect of year in milk fat, protein, and lactose. same there was a significant effect for age at weaning on birth weight, and highly significant effects for the breed, year, age of dam, sex, type of birth, and age at weaning on birth, weaning and weight gain from birth to weaning. The highest value for repeatability was 0.398, 0.309 in Awassi ewes for weight gain and in Hamdani ewes for daily milk yield respectively. Phenotypic and genetic correlation between protein and lactose in Awassi ewes 0.507 and 0.410, and in Hamdani ewes 0.641 and 0.157 respectively were highly significant.

The aim of this study was to evaluate the economic impact of the disease by using milk production records and to determine the serotypes circulating in the region during 2015. Sampling was done from different outbreaks initially on the basis of clinical signs and later reverse transcriptase-polymerase chain reaction (RT-PCR) was employed for the conformation of FMDV genome. Out of total 88 samples, 73 were found positive which were then serotyped into type O (n=44), Asia1 (n=18) and A (n=06). The economic impact was analyzed by recording milk loss at four affected farms. Their average milk yield was observed 9.2 liters before the onset of disease that decreased dramatically after the disease. Milk loss of 225 and 195 liters was recorded for buffalo and cattle respectively, during 70 days of the study period.
