Abstract
One of the most important issues in this field is the nutrition of minerals in the close up period. The aim of this study was to investigate the effect of using anionic salt supplements in traditional farms on health and production status dairy cows in Qazvin province. For this purpose, 20 non-lactating Holstein cows (with the mean parity of 3.6) were divided into 2 groups of 10 cows at the close up. Each group was randomly fed from one of the two experimental diets (two levels of zero and 250 grams of anion supplement per day) in a completely randomized design from 3 weeks before calving to calving. Milk production tended to increase when using anionic salt supplements (P≤0.10). But milk components including fat and protein percent were not affected. Reproductive parameters including the date of the first estrus after calving and the time of the first insemination did not differ between treatments. Overall, the results showed that the use of anionic salt supplements at the level of 250 g and bringing the cation-anion balance of the diet in the prepartum period to about -100 to -150 mEq / kg of dry matter diet had a relatively positive effect on milk production and due to the small number of animals used in the present project, the effect of using anionic salt supplements on animal health in traditional farms can not be conclusively commented.
