Recently, Zhang Baojia of Hefei City, Anhui Province, reported that he was currently engaged in meat pigeon breeding. However, every time in the late summer and early fall, meat pigeons need to stop production for 1 to 2 months for moulting. Brought greater losses. He asked: Is there a way to shorten the moulting cycle with less stress? What should I do?
The reporter interviewed Li Yin, a researcher at the Institute for Veterinary Research of the Veterinary Research Institute of the Jiangsu Academy of Agricultural Sciences. Li Yin introduced that at present, production of zinc sulphate, water cut, and feed cuts are often used to promote early moulting and shortening of poultry. During the moulting cycle, most of the forced moulting methods for meat pigeons are based on forced moulting.
Gao Jianfeng of the Animal Husbandry Bureau of Gaocheng City, Hebei Province, proposed in the article “Forcing moulting techniques for laying hens†that high zinc can suppress the appetite center, causing a significant drop in feed intake, and the forced moulting method has little stress and recovery of egg production. Fast, but most moults are incomplete. Operation method: During the breeding period, keep water, reduce light for 5-7 days, use natural light, and add 2.5% zinc oxide or 3% zinc sulfate to the hen for free feeding in the conventional layer chicken feed, after 6-8 days Restoring normal egg feeding and lighting. On the first day after feeding the high-zinc diet, the feed intake of the layers was reduced by half, the feed intake on the seventh day was only about 18% of the normal feed intake, the chickens stopped production, and the second week the layer recovery. After normal eating, you can start production. Gao Jianfeng also pointed out that measures such as stopping water, stopping food, and controlling light can also give strong stimulation to chickens, and can also cause premature shutdown of laying hens and shorten the period of moulting.
It is also known that the hen can also perform forced moulting by intramuscular injection of hormones such as progesterone, which results in better moulting, but can easily cause hormone imbalance in the pigeon meat. Meat pigeon breeders can use the method of forced moulting of laying hens for trial on meat pigeon breeding. However, when using high-zinc feeding methods for early moulting and shortening the moulting period, attention should be paid to the dosage of high zinc. It shows that the use of zinc sulfate, zinc oxide, etc., can shorten the meat pigeon moulting period.
During the forced moulting of meat pigeons, the hygienic management in the pens should be intensified to clean the excrement and feathers in the pens, and to disinfect the lofts, supporting facilities and the surrounding environment once a week. After forced moulting, meat pigeons should improve the quality of feed, increase the energy and protein supply in the feed, and increase the proportion of sulfur-containing amino acids appropriately. You can also add health sand in the feed, and increase the content of sulfur and gypsum appropriately to promote meat. New pigeon feather grows.
