The function of B ultrasound for sheep induce to twins
In sheep breeding technology,the technology of inducing twins is important. in this technical operation,the examination by B ultrasonic is necessary.
The technology of sovralimentazione temporanea to twins is that one month before breeding, by improving the level of nutritional supplement for ewes, in particular protein feed to prompt ewes empathema, and add a number of ovulation once time to induce ewes twins.At the same time use ultrasound to observe ewes.
Hormone treatment: ewes through marker,subcutaneous injections of hormone on 12th day or 13th day in estrous cycle can help to make double owums.Due to the differences of the varieties and the individual the response to hormone is different, it is difficult to find the appropriate uniform dose for each sheep.So it is necessaty to carry pilot study out on the specific varieties in the local to observe by ultrasound for sheep before determing the suitable dosage.This method is mostly suitable for producing single lamb varieties not for the fruitful or high mortality varieties where can be clearly observedon by ultrasound for sheep
