A virgin Jersey crossbred heifer of fourteen month of age with mammary enlargement was presented for inspection. The udder appeared swollen; similar to a lactating gland, 18-cm deep, and teats were 2.5 cm in length. The genital organ of the heifer was examined by per rectal palpation and right ovary was distended, with approximate 2 to 3 cm in diameter. The concentration of protein, fat, and lactose of mammary secretion were 10.25%, 0.2% and 0.42%, respectively; somatic cell count was 2.8×106/mL. Further, the case was suspected as mammary gland fibro adenomatous hyperplasia. The heifer was further suffering from mastitis and it was treated with broad spectrum antibiotic Ceftriaxone @ 10mg per kg body weight O.D I/M, Meloxicam 3ml O.D I/M, Mammidium powder 50gm daily for five days. In conclusion, the case was suspected to be fibro adenomatous hyperplasia of the mammary gland and the conception was not affected by precocious mammary enlargement and the heifer had full-term gestation and calving.
