Artificial duck fattening method
1. Filling a 40-50-day-old middle-duckling duck with good age and good health and normal development. Start filling when the body weight reaches 1.6-1.8kg. To fill in prematurely, the body is small and round, not too long, and more disabled. Filling in late, consumes more material, slower growth, and is not economical.
2. Prepare before filling. Before filling, generally divide the group by the mother and the mother and the body weight. If the body is poor in quality, do not fill it in. Before filling, cut the claws to prevent scratching.
3. Fill the feed, filling the fertilizer is generally about two weeks. During the period before and after the daily feed, the raw material energy is slightly lower, and the protein level is higher. In the later period, the material is just the opposite, so that it first “prepares the long meat†and quickly deposits fat later.
Before and after the material mix ratio
The preliminary materials: protein 14.7%, crude fiber 5.4%, corn flour 35%, wheat husk 30%, rice bran 30%, beans 5%.
Late material: protein level 12.6%, crude fiber 4.5%, corn flour 35%, rice bran 25%, wheat husk 30%, wheat 10%.
In the above two kinds of materials, 2% of powdered earthworms, 1% of bone powder and 0.5% of salt were added.
When hot, do not mix materials first, otherwise the alcohol will deteriorate. The ratio of water to dry material is 6:4. It is usually filled 4 times a day, 150g on the first day, 175g on days two and three, 200g on days four and five, 225g on days six and seven, 275g on days eight and nine, ten and eleven days 325g, 400g for twelve or thirteen days, 450g for fourteen days.
4. Filling methods: Before filling, the ducks should be rushed into the circle, about 100 per lap, and then rushed to the small circle next to the duck in batches. Each time they hurried into 10-20, when the ducks were filled, the ducks readily grabbed the ducks. Hold the duck's head with his left hand, open the upper and lower mouth with his thumb and forefinger, press the tongue with the middle finger, and gently squeeze the duck's esophageal bulge with his right hand, gently place the duckbill on the filling tube, push it in front of the tube, and let the hose into the pharynx. In the lower esophagus, the duck body must be parallel to the hose to avoid stabbing the esophagus. If you press the duck machine by hand, press the stem lever down with your right hand and press the packing into the esophagus bundle. After filling, fill the rod and lift it up. Then pull the duck head down and out of the filling tube. Place the duck from the hole in the feeding ring to the playground. Proficient duck workers can fill 400-500 ducks per hour.
The Laryngeal Mask Airway is the non-surgical and invasive device used for human body cavity in the short time, which is not in association with active medical devices. It can establish an artificial airway when the cuff of laryngeal mask tight covers the throat during the anesthesia and emergency treatment. It is also useful in situations where manipulation of the head or neck to facilitate endotracheal intubation is difficult or unsuccessful.
Speciality:
-Eliminates all possibility of infections being transmitted between patients
-Flexible optic fibre makes access easy
-Thanks to the semi-transparent tube, condensation is clearly visible
-Does not induce laryngeal spasms
-Reduces the risk of obstruction of the upper respiratory tracts
-Lesser incidences of hypoxia
Various laryngeal mask can be choosed in laryngeal mask intubation kit, such as pvc laryngeal mask, pvc reinforced laryngeal mask, silicone laryngeal mask, silicone reinforced laryngeal mask airway.
