Nymphomania with sex reversal in a Sahiwal Heifer
quality. Thereafter, the heifer was milked freely every day with the ex-
press purpose of helping her to develop all the qualities of a normal cow,
and she yielded an average of three pounds of milk on a bare ration of roughage
only. Since the day, she began yielding milk, a remarkable change took place
in her masculine characters. She was found to be quiet, more temperate in
her general behaviour and free from perverted habits. She stopped roaring
and showed no desire to hunt after cows on heat. Still she showed no signs
of oestrum.
To start the oestrus cycle, she was subcutaneously injected on the 18th
March, 1938, with 82 c.c. of a detoxicated mixed urine from a cow and a
heifer in advanced pregnancy, for four consecutive days. When she did not
come on heat even after this treatment, she was examined on the 27th April,
1938, and her genital organs were found normal and the ovary treated for
cyst had now grown to the size of pigeon egg and was quite sound. The
ovaries were again massaged and the uterus was douched as before. On the
following day she started roaring like a bull, but after two days she was quite
normal again, on putting her under a course of potash iodide. At this stage
she was yielding four pounds of milk per day.
On the 7th May, 1938, she came on heat and when she was put to the
bull, she was accommodative just like other heifers under normal conditions
and allowed herself to be followed by the bull without the least resistance,
but the bull did not cover her. Evidently, she was passing through a feeble
heat of very short duration. On the 29th May, she was again on heat (exactly
twenty-one days after the last heat) and was served by the stud bull—Shanker.
After the service, she showed evidence of violent pain of hard service which
subsided after eight hours. Subsequent to this, she was on heat on the 29th
June and 18th July and on both the occasions, she was covered by the same
bull. She reverted again on the 4th August and was served this time by the
stud bull—Emden, who finally settled her in calf. As she advanced in
pregnancy, it was quite apparent that her mental and physical male characters
were steadily becoming transformed into those of the true female. The heifer
calved on the 19th May, 1939, and, at present, she is giving 38 lb. of milk
per day (Plate II Fig. 2). At present she is devoid of every nymphomanic
trait, and is in every respect a normal young cow.
Throughout the course of her treatment and till she was three months
pregnant and during the period she was yielding milk, she was getting only
roughage, viz. oats straw and jowar (Andropogon Sorghum) silage, and the
latter was fed to her whenever available. Milking discontinued when she
was over three months pregnant, and since then she was fed up to the time
of calving with three pounds of concentrates in addition to the roughage.
She yielded as an uncovered heifer 449¼ lb. milk in 142 days and as a
covered heifer she yielded 153¼ lb. of milk in 76 days. Details of her
pre-milk yield are given in Appendix A.
The analyses of her pre-milk (Appendix B) show no difference from the
milk of a cow in normal condition. The milk was sent to the Nutrition Sec-
tion where a feeding experiment on boys was conducted.
The two photographs show the heifer before and after the treatment
(Plate I, Fig. 2 and Plate II, Fig. 1).
