Metabolic profile and reproduction performance in cows during the puerperal period

The relationship between metabolic profile in cows and the efficiency of reproduction performance involves an integrated complex of the endocrine system as well as the metabolic signals that control the metabolism and the reproduction process in cows. The number services per conception in cows has proven statistically correlative connections with inorganic phosphorus, magnesium and glucose in the before calving period, but there are not proven statistically connections with other metabolic indicators in the same period. In the period about two weeks after calving there is only one statistically proven connection with magnesium in blood serum.Meanwhile in the period of one month after calving there is one connection statistically proved, with glucose, and in the two months after calving period there is a statistically proven connection only with the urea.Correlative relationships of metabolic indicators taken for study during the calvingconception interval indicate that the correlations are weak and statistically unproved in thesefourth physiological states.
