Effect of Mineral Mixture Supplementation on Haemato-biochemical Parameters of Anoestrus Cows in Winter and Summer Season

Abstract

Background: livestock is mainly reared under a crop livestock integrated farming system and mineral supplementation is not common practice. Out of all nutrients, minerals and vitamins play a crucial role in metabolism, lactation, reproduction and even for microbial fermentation in rumen. Considering the mineral deficiencies in particular zones, the area specific mineral mixtures (ASMM) were formulated for various zones and also found various limiting nutrients in different zones of MP. The current study was planned to find out the effect of mineral mixture supplementation on body weight, body condition score and haemato-biochemical profile of non-descript anoestrus cows. Methods: A total-forty-eight animal were selected out of the surveyed animals and divided into four groups (n=12) viz. T1 (Normal cyclic animals), T2 (Anoestrus Control), T3 (True anoestrus) and T4 (Sub-oestrus). The experiments were carried out in two seasons (summer and winter). All physiological and hemato-biochemical parameters were recorded and analyzed as per standard mentioned protocol. Result: According to the findings of this experiment weight gain the animals of the true anoestrus and sub-oestrus group’s recorded highly significant increases in the winter and summer seasons. The haemoglobin concentration was within the normal range and it was non-significant in all groups except normal cyclic animal (T1) in winter and true anoestrous (T3) in summer after the mineral supplementation. There was no significant difference in the WBC count of all groups except in sub-oestrous control (T2S) and T1 in the winter season. RBC concentration was non-significant in almost all groups. Erythrocytic indices were the normal limits and did not differ significantly in the majority of groups except significant difference showed are MCHC in T3, MCH in T2S, MCV in T1 of winter seasons and were within normal range in all supplemented groups in both. The serum cholesterol concentration showed significantly higher value in the winter and summer season of T3 group. However, in sub-estrous (T4 group) animals, the values in the winter season were significantly higher. We observed significantly higher values of triglycerides in T3 and T4 groups in winter and T3, T4 and T1 groups in summer seasons. The above results indicate the beneficial effects of mineral mixtures in supplement groups. Studies conclude that the supplementation of mineral mixtures can improve reproductive efficiency in non-descript anoestrus cows.
