Ultrasonographic biometry of the ovaries and follicles in cyclic and non-cyclic Kundhi buffaloe

Abstract

Ultrasonographic and morpho-biometry of the ovaries and follicles of cyclic and non-cyclic Kundhi buffaloes was studied. The buffalos were measured for their left and right ovaries using ultrasonographic and morpho-biometry of the ovaries. The age of non-cyclic buffaloes was 10 ± 2.0 years, and cyclic buffaloes was 8.33 ± 1.87 years; body weight of non-cyclic Kundhi Buffaloes was 377.14 ± 52.19 kg and cyclic buffaloes was 380.77 ± 89.69 kg; the body condition score of non-cyclic buffaloes was 3.78 ± 0.395 and cyclic buffaloes was 4.25 ± 0.43. Statistically, the differences for age and body condition score were significant (P<0.05) and non-significant (P>0.05) for body weight. The ultrasonographical biometry in the length of the left and right ovaries in Kundhi buffalo was 28.68 ± 4.80 and 31.44 ± 6.29 mm, 12.62 ± 2.20 and 12.61±2.51 mm in width, 5.81 ± 1.11 and 5.94 ± 1.66 mm in thickness, 64.28 ± 10.40 and 71.73 ± 11.33 mm in circumference, and 2.61 ± 0.76 and 3.08 ± 0.75 cm2 in volume, respectively. The differences in the length of the left and right ovaries, circumference, and volume were significant (P<0.05) and non-significant (P>0.05) for width and thickness. The morpho-biometry results indicated that the length of the left and right ovaries was 28.88 ± 5.30 and 30.31 ± 6.61 mm, 14.00 ± 1.83 and 14.00 ± 2.10 mm in width, 6.94 ± 1.12 and 7.06 ± 1.65 mm in thickness, 65.00 ± 7.75 and 68.44 ± 9.44 mm in circumference, and 5.88 ± 2.00 and 5.44 ± 1.63 gm in weight, respectively. The differences in the length, circumference, and weight of left and right ovaries were significant (P<0.05) and non-significant (P>0.05) for width and thickness of ovaries. The number of primary follicles on left and right ovaries was 1.00 ± 0.97 and 1.31 ± 1.08, secondary was 3.31 ± 2.85 and 3.63 ± 3.01, tertiary was 6.38 ± 1.59 and 6.81 ± 2.34, circumference of follicle on the left and right ovaries was 17.58 ± 5.52 and 16.69 ± 4.20 mm, and volume of the follicle 0.24 ± 0.14 and 0.21 ± 0.10 cm2. The differences in primary follicles, circumference of the follicle on the right and left ovaries were significant (P<0.05) and non-significant (P>0.05) for secondary, tertiary, and volume of follicles on left and right ovaries. The length ovaries in cyclic and non-cyclic Kundhi buffalo was 30.22 ± 6.85 and 29.89 ± 4.43 mm, ovaries 12.65 ± 1.68 and 12.57 ± 2.57 mm in width, 6.58 ± 1.61 and 5.58 ± 1.11 mm in thickness, 70.63 ± 13.06 and 65.38 ± 8.97 mm in circumference, 2.96 ± 0.79 and 2.72 ± 0.76 cm2 in volume, 6.00 ± 2.06 and 5.31 ± 1.49 gm in weight, respectively. The number of primary follicles on ovaries of cyclic and non-cyclic Kundhi buffaloes was 2.31 ± 1.08 and 0, number of secondary was 5.25 ± 1.77 and 0, number of tertiary was 7.31 ± 1.69 and 3.06 ± 1.30, 17.88 ± 4.93 and 12.30 ± 3.46 mm in circumference, and 0.25 ± 0.13 and 0.10 ± 0.08 cm2 in volume, respectively. The differences in thickness, circumference (O), weight, number of primary, secondary, tertiary, circumference (F). and volume (F) of follicles of cyclic and non-cyclic Kundhi buffaloes were significant (P<0.05) and non-significant (P>0.05) for length and width of follicles of cyclic and non-cyclic buffaloes.
