Cow metabolic status assessed from fat/protein ratio in milk affected ovarian response and number of transferable embryos after superovulation

Popis výsledku v původním jazyce

This work aimed to evaluate the quantity and the quality of flushed embryos based on the metabolic status of dairy cows, lactation number, and size of the ovaries. Fifty-nine Holstein cows on 1st to 5th lactation were enrolled in the experiment. Monitoring took place during the period from October to November and from March to June. Cows with corpus luteum were included for the hormonal treatment, superovulation and timed insemination. The cow was inseminated, resp. reinseminated, during the induced heat with insemination doses from one bull from the same batch. Embryo flushing was performed on the 7th day after the first insemination. We isolated individual embryos after flushing, and morphologically evaluated them under a stereo microscope. The metabolic status of tested cows was determined based on the ratio between fat and protein in milk around the period of embryo flushing (under 1,1, 1,1 to 1,3, over 1,3). Data about fat and protein content were taken from milking parlour records. Data were ev
