Abstract

Background and objectives: Based on studies, there is a need to determination of blood parameters of dairy cows especially during the transitional period to assess the physiological status of cows and following that to assess NUTRITIONAL STATUS of them and in case of diet imbalance and possible deficiency in the farm, diet is balanced and reducing the quality and quantity of milk production can be prevented, also it may cause increase of reproductive efficiency. Therefore, the aim of this study was to evaluate the NUTRITIONAL STATUS of fresh cows through BLOOD METABOLITES and providing suitable strategy to improve the nutrition of this group of dairy cattle.Materials and methods: seven DAIRY FARMS which are members Union of Agricultural Cooperatives livestock industry in Isfahan random from each of the 7 postpartum cows were selected and sampled. Sampling was conducted in July 2013. Samples for measurement of cholesterol, albumin, urea nitrogen, total protein, glucose, BHBA, NEFA, calcium and sodium blood were sent to the laboratory. Data was then analyzed based on randomized completely design. Duncan’s analysis used for comparison means of DAIRY FARMS, as well as, each of the metabolites through t test were compared with the normal range.Results: The results showed that the blood sugar level of dairy cows in some of DAIRY FARMS was lower than normal value (50 mg dL-1) in summer (P<0.05), so that 65.3 percent of samples had lower than normal level of blood sugar. Also, the majority of dairy cows blood sodium levels were lower than normal level. Blood albumin content of 39 percent of samples was lower than normal level. Open day was high in the most of farms (even more than 6 month). The farms had different significantly in content of blood NEFA, glucose, calcium and sodium (P<0.05). There was no significant difference between the farms in the other factors.Conclusion: generally, it can be concluded that there was sodium deficiency during early lactation in the most of farms. The lower level of albumin, glucose, sodium and calcium in some of case than the normal levels can be key factors in increasing of open days in the most of DAIRY FARMS.
