Metabolic profile and hormonal status comparison between prımıparous and multıparous non-cyclıc cows

| description | Several reports indicated that a large proportion of dairy cows have not resumed cyclicity until day 60 after calving. These cows are traditionally classified as non-cycling (anoestrous or anovular cows). Static ovaries (SO, lack of luteal tissue and follicles >8 mm, and progesterone < 0.5 ng/mL) could be a possible underlying reason that contributes to a non-cycling status. Although SO affects both primiparous (PP) and multiparous (MP) cows, PP cows are more prone to be non-cycling than MP. Therefore, this study aims to compare the metabolic profiles and hormonal status between non-cycling PP and MP cows diagnosed with SO. One hundred and twenty one animals that did not express signs of oestrus until day 60 postpartum were grouped by parity (PP, n=58 and MP, n=63), then blood sampled and examined using transrectal ultrasonography. Blood samples were collected before the ultrasonographic examination. Out of those, 42 PP (72.4%) and 28 MP (44.4%) were diagnosed as non-cycling (bearing SO). Serum concentrations of triglycerides, cholesterol, total protein and albumin did not differ between parity groups. The glucose concentrations in PP cows (1.43 ± 0.59 mmol/L) and MP cows (1.69 ± 0.71 mmol/L) did not differ, however, they were less than the normal physiological concentration. In addition, no differences were detected between parity groups for concentrations of NEFA, β-HBA, progesterone and estradiol. In summary, we concluded that non-cycling PP and MP cows bearing SO have similar hormonal status and metabolic profiles. |
