The present research work was carried out to study the occurrence of subclinical endometritis, oestrus characteristics such as duration and intensity of oestrus and physical properties of oestrual mucus in repeat breeder (RB) cows and its association with age of the animal. Data on the occurrence of repeat breeding for the past three years were collected from breeding registers maintained at Livestock Research Station, Thiruvazhamkunnu. An overall occurrence of 21.08 per cent was noticed with a gradual reduction from 22.27 to 20 per cent. Further, the occurrence of various reproductive disorders for a period of 18 months was collected from the data available in the registers and by clinicogynaecological examination and repeat breeding was observed to be having the highest occurrence (34.34 per cent). Subclinical endometritis (SCE) was screened using the Whiteside test and cytological endometritis was diagnosed using modified cytobrush technique (PMN cells ≥ 5 per cent) and the incidence of SCE and cytological endometritis in RB cows were 22.58 and 9.67per cent, respectively. There was no significant difference (P > 0.05) in the occurrence of SCE in RB cows below and above six years. The intensity of oestrus was assessed using a scorecard and classified into high, medium and low by observing behavioural, physiological signs and gynaecological examination. The oestrual mucus of 24 RB cows free of SCE was examined and physical characteristics like colour (transparent, cloudy, dirty), consistency (thick and thin) and volume (copious, moderate, low) were noted. Among 24 RB cows 54.16, 41.67 and 12.50 per cent exhibited high, medium and low intensity of oestrus, respectively and the mean duration of oestrus was found to be 27.50 ± 1.50 h. The majority of RB cows exhibited copious (50 per cent), transparent (83.33 per cent) thick consistency (66.67 per cent) oestrual mucus. There was no significant difference (P > 0.05) in the colour, consistency and volume of oestrual mucus in RB cows below and above six years.
