Abstract
In the present study changes in luteal fresh weight and concentration of collagen in cyclic buffalo corpus luteum were investigated at 4 stages of its growth and development/regression The collagen concentration was determined by estimating hydroxyproline a collagen specific amino acid present in luteal tissues The mean fresh weight increased P 0001 over the luteal phase reached maximum at lateluteal stage and decreased P 0001 subsequently at follicular stage The weight of the mature CL was 25 times heavier than the CL haemorrhagicum and regressing CL Results showed that cyclic buffalo CL contains collagen at all 4 stages of development during oestrous cycle The collagen in luteal tissues constitutes about 09 to 12 of luteal fresh weight with the highest content appearing in mature tissue The concentration of collagen increased P 0001 with the stages of CL development over the luteal phase and the highest concentration was recorded at follicular phase with the decline of luteal weight The total content of collagen per CL also showed the same trend during luteal phase but decreased at follicular phase with the loss of luteal tissues In conclusion collagen concentration in cyclic buffalo CL changes with the growth and development of CL across the oestrous cycle The synthesis of collagen is faster between early to midluteal stage than mid to lateluteal stage
