  Herd health and comprehensive preventive medicine were notified since the last half of 20th century, as the farmers were better educated and the value of individual animals relative to veterinary fees has decreased. Restricted attention had been given to the above idea leads to misunderstanding of infectious and non-infectious diseases. Currently, veterinarians must support herd health programs designed to increase production by preventing disease, rather than just dispensing traditional treatment to clinically sick animals. Lameness as one of the costliest disorders in dairy herds, needs special attention. Both preventive costs (such as hoof trimming costs) and the losses due to heifer replacements and milk yield reduction should be counted as the economic losses of a disease. Indeed, local data play an important role in estimating lameness losses. Calculating measures of morbidity is a key point that helps the veterinarian and the farmer to know about the farm condition. So, in this article the economic importance of lameness and the concept of prevalence and incidence of it were reviewed. At the end there are some information about the prevalence and incidence of lameness in Iran and some other countries. Manuscript profile

  Each case of dystocia is a clinical problem that may be solved if a correct procedure is followed. The diagnosis and treatment of dystocia requires a good understanding of normal parturition and sensitivity to the welfare of both dam and offspring. Difficult birth will occur when the expulsive forces are insufficient, when the birth canal is of inadequate size and shape, or when the presenting diameter of the fetus is unable to pass through the normal birth canal because it is too large or its disposition prevents it from doing so. The incidence of dystocia in heifers has been calculated to be anywhere from three to ten times that of multiparous cows, whether in beef or dairy cattle. Risk factors for dystocia are fetal-dam disparity, abnormal fetal position, vulval, vaginal, or cervical stenosis and uterine torsion. Preventing dystocia, particularly in first-calf heifers, is a very important component of a successful reproductive program on any dairy or beef operation and there are numerous factors have been involved in the incidence of dystocia. Even when plans are in place to limit dystocia risk to an acceptable level (<15% for heifers, <5% for cows), there are still cases of dystocia in beef and dairy herds. One of the most important fundamentals for optimum dystocia management is for the owner to know when to intervene or call for assistance. Manuscript profile

(ages, 15, 16, 17, 18, years) (Mean ± SD: 7.0 ± 6.15 years): The overall prevalence of overweight among the subjects was 20.5% and the overall prevalence of obesity among the subjects was 6.8%. The prevalence of abdominal obesity among subjects was 27.4%. The analysis of inferential findings has shown that there is a direct relationship between the amount of watching TV and working with the computer, food pattern and body mass index at an error level of less than 0.05 and a confidence level of 95%.
