How to distinguish between male and female pigeons?
Body shape identification method: the male pigeon is too large, the top of the head is broad and the feet are slightly raised, the neck is thick, short and hard, the female pigeon is compact and graceful, the whole head is narrow and long, the eye ring is close to the rhinoma, and the neck is slender and soft.
Temperament identification method: the male pigeon is majestic, aggressive and purring, while the female pigeon is gentle and quiet, not aggressive, weak resistance, no gnawing sound or only a low whining sound.
Feather identification method: the thicker the neck feather of the male pigeon is, the purple-green metallic luster is more bright, the tip of the main wing is round, the tail feather is dirt, the neck feather of the female pigeon is slender and soft, the golden luster is not as bright as the male pigeon, the wings are tighter, and the tail feathers are clean.
Bone identification method: the cervical vertebrae of male pigeons are hard and strong, the sternum is long and slightly curved, the keel is protruding, the distance between the end of sternum and egg bone (pubis) is close, and the distance between pelvis and two pubic bones is narrow and tight. The cervical vertebrae of female pigeons are thin and soft, the sternum is short and straight, the distance between the end of sternum and pubis is wide, the keel is protruding, and the distance between pubis is wide and elastic.

Deer feed with sodium humate to produce more antler.
According to the deer farm experiment of 597 Farm Agriculture and Forestry Company, using sodium humate as deer feed additive increased deer food and drink, exuberant metabolism, and provided sufficient nutrition for the growth of pilose antler. According to the experiment, each stag was fed 0.2 grams of compound sodium humate three times a day. Two hours before feeding, the solid compound sodium humate was diluted to 0.05% with a PH value of 6.5, and then fed with green feed for 70 consecutive days until the antler was collected. The results showed that the per unit yield of pilose antler was 575g in the test group and 490g in the control group, with an increase of 17%.

Technical measures to increase the yield of royal jelly
Increasing the yield of royal jelly is an important guarantee to improve the economic benefit of beekeeping. The following five technical measures should be taken to increase the output of royal jelly. 1. In honeybees, royal jelly is secreted by young bees and is the main food for queen bees and bee larvae. Therefore, in order to increase the yield of royal jelly, there must be more strong colonies of young bees, and the production of royal jelly must be adjusted in time. If there are only 6-7 frame-footed wasps, the high yield of royal jelly cannot be obtained. To this end, it is necessary to increase the number of youth.
