Repair and treatment of ruptured bovine nasal speculum
The rupture of the cow nasal mirror is that the nose lip is broken into the upper and lower free ends, so that the cow can not wear the nose ring or pierce the nose, which is difficult because of the inconvenience of control.
I. treatment
Repair the rupture of nasal endoscope with surgical treatment.
2. Methods
Routine preparation, Baoding can take recumbent or standing. The infraorbital nerves on both sides were anesthetized with 10 ml of 2% procaine hydrochloride on each side, and the upper and lower nasal endoscopic lips were ruptured with infiltration anesthesia. after disinfection, the broken part was clamped with special long flat mouth forceps (two small bamboo slices can also be used). Fix the base of the broken end of the nose, thoroughly remove the scar tissue of the wound, at the same time, the wound should be neatly cut into a protruding end around the middle of the free end above. The middle of the lower free end is cut into a depression, the two happen to be opposite, chimeric with each other, the section should be large, so that the upper and lower sections are completely consistent. After the new wound was washed with normal saline, the two sides of the wound were ligated with penicillin powder or aminobenzenesulfonamide powder, buried suture with two needles and tubercle suture with three needles, and ligation with two needles for the first time. During the second three-needle suture and ligation, it was checked that the tightness of each thread was suitable, symmetrical up and down, and triple knot was made to prevent the wound from being inverted. Leave the thread 1 cm long to cut off the remaining thread, then clean the clots around the operation department and apply iodine tincture.
III. Nursing
7 days after the operation, no grazing, feeding green soft material, less water to add frequently, to prevent sewage infection. If there is no infection and suppuration of the wound, the stitches can be removed 10-14 days after operation, and the nose can be pierced again after 1 month. If the wound is infected and suppurated, rinse with 3% hydrogen peroxide or 0.5% potassium permanganate solution, then apply sulfonamide solution, and then apply sulfonamide ointment.
IV. Curative effect
For many years, 8 cases of cattle with broken rhinoscope were repaired by this operation, all of them anastomosed well after one-time operation, and none of them were repaired again, and the curative effect was very satisfactory.
5. Experience
1. Cows with 6 months of pregnancy are generally repaired after delivery; there are too many defects after nasal mirror fracture, and it is not easy to perform surgery due to nostril stricture after repair; rhinoscope fracture is not suitable for operation during the development of inflammation; it is generally more appropriate to perform surgery in farming or autumn.
two。 Nose piercing parts should be suitable, and it is forbidden to use wire or bamboo pieces to pierce or make nose rings. For ferocious cattle, do not be rough and tough when in service.
3. Feed less concentrate the day before operation, but not on the day of operation.

The male goose is castrated and fattened.
Except for a small number of male geese raised by the rural people according to the traditional feeding method, most of them are fattened and sold as meat geese. This old feeding method has the advantages of long feeding time, slow growth and development and low breeding efficiency. If the male goose is castrated and then fattened, not only the goose is docile and easy to manage, but also grows fast, has a large size and has high economic benefits. In order to further improve the breeding efficiency of goose farmers, the castration methods of male geese are introduced as follows: 1. Castration season

Skillful processing of fine peeling sheepskin
The economic value of sheepskin is relatively high. Doing a good job in peeling and primary processing of sheepskin can increase economic income and improve sheep raising benefits. Now on the sheepskin stripping and primary processing technology to the readers for a brief introduction: peeling. Goats, brocade sheep, most people still use the "big wipe neck" traditional sheep slaughter method. This method tends to contaminate the fur with blood and affect the integrity of the sheepskin, reducing the quality of the skin. A better way to kill sheep is to fix the sheep and cut the skin longitudinally on the neck of the sheep with a knife. The incision is about 7~10
