The Effect of the addition of VemoHerb T (reproductivity enhancer) over the artificial insemination of ducks parent flock.


Subject: Field trial to show the effect of the addition of VemoHerb T (reproductivity enhancer) over the artificial insemination of ducks parent flock.

Aim of the experiment: The experiment was conducted on drakes (male ducks) (assessing single ejaculate semen volume, sperm motility) and female laying ducks (assessing laying capacity, egg weight).

  • The parent flock is approaching the end of their egg-laying period - 40 days before the end.
  • Experimental group: male - 86 drakes, female - 860 ducks
  • Control group: male - 192 drakes, female - 1720 ducks
  • Daily dose of VemoHerb T: 15 mg / kg live weight
  • Start of the experiment: 10.02.2013
  • Duration of the intake VemoHerb T: one month (till10.03.2013)
  • End of the experiment: 26.04.2013

Conclusions:

  1. Drakes respond positively to VemoHerb T and despite their age, there is significant increase in the semen volume for ejaculation and its mobility.
  2. Female laying ducks respond positively, even though there is a slight difference in the laying capacity and egg weight.
  3. There were two hatching of the observed eggs and the result varied: The first hatching: - 0.8% for the control group and the second: + 2.8%, but there are many side factors involved and the two experiments were not enough for a firm conclusion.
  4. Considering that the ducks are at the end of their egg-laying period, i.e. the most difficult time to influence their condition, the product certainly has a positive effect on them.

Recommendations:

The nutritional feed supplement VemoHerb T is suitable for stimulating drakes used for artificial insemination. There is a positive effect on the female laying ducks, but for more reliable data it is appropriate to experiment with ducks at an earlier stage of laying and with a higher number of hatchings.
