IN CROSSBRED CATTLE

Need • • • • • ?CROSSBRED HEIFERS ARE GENERALLY NOT CONCEIVING EVEN UP TO 5 YEARS OF AGE.

LACTATING CROSSBRED COWS ARE NOT CONCEIVING AFTER 2ND OR 3RD LACTATION.

A LARGE NUMBER OF CROSSBRED ANIMALS ARE BECOMING STRAY ANIMALS DUE TO REPRODUCTIVE FAILURE.

OBJECTIVES

1.To get milk production from unproductive,

dry, non-pregnant heifers and crossbred cows.

2. To make correction in the estrus cycle of

anoestrus or repeat breeder cows.

3. To prevent crossbred female animals to

become stray animals.

SELECTION OF THE ANIMAL• Animal should be crossbred.

• It should have teats and udder.

• Animal should be dry and non- pregnant.

• Animal can be a repeat breeder or anoestrus.

Hormonal treatment for milk induction

Method -1 Long duration treatment

Day 1 TO 7 Inj. Progesteron 50 mg.i/m per day for 7 days.

On day 12,13 and 14

Inj. Progesteron 0.25 mg/Kg b.w plus Inj. Oestradiol 17-B 0.1 mg/kg b.w intra muscular.

On day 19,20,21 and 22

Inj. Reserpine 4 mg i/m for 4 days.

Start milking the animal after 15th day. Discard total milk production for 20 days after the last injection given to the animal.

Hormonal treatment for milk induction

Method -2 Short duration treatment

Day 1 TO 7 Inj. Progesteron 0.25 mg/Kg b.w plus Inj. Oestradiol 17-B 0.1 mg/kg b.w intra muscular for 7 days.

On day 10,11 and 12

Inj. Reserpine 4 mg i/m for 4 days.

Start milking the animal after 8th day of treatment. Discard total milk production for 20 days after the last injection given to the animal.

Hormonal treatment for milk induction

Method -3 Short duration treatment

Day 1 TO 12 Inj. Progesteron 0.2 mg/Kg b.w plus Inj. Oestradiol 17-B 0.07 mg/kg b.w intra muscular for 12 days.

On day 13,14 and 15

Inj. Dexamethsone 20 mg i/m for 3 days.

Start milking the animal after 10th day of treatment. Discard total milk production for 20 days after the last injection given to the animal.

BENEFITS1.80 per cent crossbred animals respond to this hormonal treatment and start yielding milk varying from 7 to 10 litres in heifers to 15 to 20 litres in crossbred cows.2. There are 80 per cent chances that the treated animals will conceive in coming days either by following natural service or through artificial insemination.3. Anoestrus animals may come in regular estrus after following hormonal treatment.4. There is nothing wrong in the milk obtained after artificial induction of lactation in animals for human consumption after 30 days of treatment.5. Treated animals may yield milk till 270 to 400 days after getting treatment.6. After giving a rest period of atleast 50-60 days, the same animals can be retreated with these hormones, if not conceived naturally.

DiscussionA total of 13 mature cross bred animals were given hormonal treatment. 12 animals started milk production varying from 3 to 9 litres per day. Thus, per cent success obtained was 92.3.

4 animals were heifers who did not conceive till the age of 4-5 years, when given induction produced milk between 6.5 lt to 8.5 lt./d.

Age of other animals was between 9 to 14 years. All of them were dry and not conceiving for the last 3 to 4 years. The owners of these were helpless. The induction of milk through hormones gave them a big relief and all of them are very much satisfied.

As expected, 2 cows out of 8 treated with hormones became pregnant.

Total cost of hormonal injection is just Rs. 1000/-only.

CONSTRAINTSThe effect of hormonal treatment is variable in increasing milk production.

Success rate varies between 80 to 90 per cent.

Not suitable for buffaloes.
