Hatching There are two methods of hatching: the natural method, that is, by means of a broody hen and the artificial one by means of incubators. Incubators may be of the hot-air or hot-water type. Care should be taken in the selection of eggs for incubation. They should be of average size and proper shape. Neither badly shaped eggs nor those with very rough or thin shells should be chosen. Eggs for incubation should be clean and as fresh as possible. They should never be kept for longer than one week before setting. Five days is the usual time. The fresher are the eggs the better, since the percentage of hatching will be higher in this case. The temperature and humidity in incubators are regulated automatically. It is important that ventilation should be provided. Chicken Rearing Chickens may be reared either by a broody hen or in various types of brooders. Battery brooders are widely used on big poultry-breeding farms because of their being adapted for large-scale rearing over a long period. - 53 - They consist of a series of compartments one on top of the other and all are heated by the same heating apparatus. Being 8 weeks old, cockerels are to be separated from pullets and if they are not to be kept for breeding purposes, they should be fattened up for table. The pullets are removed to their permanent laying quarters when they are 4 to 5 months old. No food is required for chicks for 24 hours after hatching. But they should be given warm water or milk and fine grits. Many different systems of feeding chicks are practised. The most common and successful one is to feed dry mash in hoppers opened all day long or shut periodically. In addition two feeds of grain are given to them, one in the morning and the second in the evening. It is necessary that chicks should have a free access to water as well. Broilers Young meat chickens at about six or seven weeks are referred to as "broilers". The quality of meat at this stage is excellent. High-quality broiler meat is achieved due to their being fed high-protein or high-energy rations. Chickens are usually raised on deep litter in intensive houses to the stage of broilers. The space, ventilation and feeding are the main factors which must be paid attention to when raising broilers. This system is spoken about as the most popular and successful method of raising chickens to the broiler stage. Пояснения к тексту

They may be classified in the same way as fowls, that is, egg-producing breeds, breeding breeds and table breeds. At present ducks are mostly kept for table. It is recommended that ducks should be fed two or three times a day. A common method is to give a grain feed in the morning and in the evening and a wet mash at midday. When on free range, birds may require no feeding in the morning. The weather being frosty or very dry, they should be fed in the morning as well. Some grit and a plentiful supply of drinking water should be provided. When fattened up for table purposes, ducks should be kept in small runs* with no swimming water and should be fed barley meal**. Ducklings are usually killed for table at 7 to 12 weeks old when they weigh 4 to 5.5 pounds. Ducks start to lay at 6 or 7 months. They usually moult*** in June and come into lay again about the beginning of September. Duck eggs may be hatched either by a hen or in an incubator. A hen will cover 9 to 10 duck eggs. Duck eggs being hatched in an incubator, a lower temperature is needed for them than for hen eggs. Повторение темы "Poultry" I. Прочтите текст и объясните, чем отличаются два метода спаривания птиц.

II. Прочтите текст. Ответьте на вопрос: what conditions should be provided for chicks in a brooder? Chicken Rearing Chicks may be either reared by a broody hen or artificially. There are various types of brooders but the principle used is the same in all of them. They are heated by some kind of heating. The main factors in rearing chicks artificially are:1) to provide enough heat, too much heat or too little heat are both harmful, 2) to avoid draughts** and 3) to avoid overcrowding***. The temperature of the brooder should be 95F when 24 or 36 hour old chicks are placed in it. The temperature should be gradually reduced to 75F when the chicks are 6 weeks old. The brooder should be cleaned every week.  *run - вольер**barley meal - ячневая мука ***moult – линять -58- *fertile – оплодотворенный **draughts - сквозняк ***overcrowding - скученность -59 - III. Прочтите текст. Переведите то место в тексте, где говорится об использовании мешанки для несушек. Feeding Modern poultry growers do not usually mix their own feed. Now it is more economical to buy* mixed feed. They buy chick mash, growers mash and layers mash. Chick mash is fed for the first eight weeks. Then it is gradually replaced by growers’ mash which is fed until layers mash is introduced, which should take place when about 25 per cent of the flock have started to lay. During the year the light breed such as the White Leghorn will eat about 80 pounds of feed. Heavier breeds will average 10 pounds more. IV. Прочтите текст и скажите, как влияет температура воды на состояние и яйценоскость птиц. Watering Clean fresh drinking water is highly important. During summer it should be kept in a shady** place, as sun-heated water is harmful to the birds. In the winter time it is advisable to place water in a warm place. The birds will not drink very cold water If the birds do not get an adequate amount of water the egg production will quickly be decreased. V. Прочтите текст и выполните задание, данное после текста. Broilers On some poultry farms the main aim is not the production of eggs but the production of table birds. The young meat birds at the age of about 7 weeks are known as "chickens" in England, "broilers" in the United States and "grillers" in Australia. It is because of the high quality of meat that broilers are so valuable. Their meat is rich in protein, fats, minerals and different vitamins. *  buy - покупать-60- ** shady – тенистый High-nutritious feeds should predominate in broiler rations. Dry mash should always be available. Of the grains corn and wheat are most desirable. The fibre content in the ration should not be more than 4%. There are different methods of rearing chickens to the “broiler” stage. The most popular method is keeping them on deep litter in intensive houses. Исходя из содержания текста, закончите следующие предложения:
Geese Geese grow best on unlimited range and need very little feeding in addition to pasture. They are usually unsatisfactory when kept in confinement. Swimming water is not essential but is appreciated* by the birds. It is likely to improve fertility, though equally good results have been obtained when no water is available. Geese are long-lived and remain prolific up to 10 years. The birds should be mated at least a month before fertile eggs are required. The geese start laying when 10 or 11 months old. When birds are on free range they will only require one feed a day to keep them in good breeding condition. During the summer months feeding may be unnecessary, but in spring the grass is often scarce and there is a need for one feed per day. This should consist of 20 ounces of mixed grain. It should be fed in the evening. Eggs may be hatched either by the geese or by hens or in an incubator. Hens are generally preferred as it is essential to keep the goose laying throughout the season.A hot-water incubator is satisfactory for hatching goose eggs. *  Appreciate - (высоко) ценить, любить-61- Particular attention should be paid to the moisture in the machine. With both hen and incubator hatching the eggs should be sprinkled* with warm water once daily for the last 10 days. Ответьте на вопросы (устно):

ARTIFICIAL INSEMINATION The artificial insemination technique has received increasing attention in many countries. It has been used in all domestic animals and poultry, but it is most extensively used for cattle breeding. There are now few cattle-raising countries the artificial insemination technique is not practised in. The artificial insemination technique has many advantages over the ordinary service. By artificial insemination the number of cows served by one bull can be increased from the normal average number of between 30 and 50 per year by natural service, up to between 300 and 700 and in special cases up to 10.000 or more. By means of this method the improvement in breed type, production and quality can be more rapidly effected, provided that only tried and outstanding sires are used. A smaller amount of bulls is needed and consequently more rigid methods of selecting bulls can be practised. This results in the elimination of inferior bulls from breeding and in the improvement of the quality of the cattle. In certain cases artificial insemination may be a means of preventing infertility, since it is possible to examine a bull's semen, which cannot be done with ordinary service. Artificial insemination technique includes semen collection, processing of semen, freezing semen and insemination techniques. When collecting semen, special attention should be paid to - 63 - preventing any possibility of contamination by dust, dirt or chemicals. Clean collecting equipment is essential. Soon after collection the semen is diluted with a diluted at the same temperature as the semen. Diluents, as milk, for instance, offer protection of the sperm during temperature change. Diluted bull semen can be stored at 5°C for 3 or 4 days. Ram or boar semen is ordinarily used within a day or two after collection. Stallion semen does not store well and is usually used during the first day after collection. To bе stored for a long period, the semen should be frozen. The results the experienced breeders obtain with frozen semen have proved to be as successful as those with liquid semen. Frozen semen can be transported over long distances when stored in chests containing dry ice or liquid nitrogen. Transporting frozen semen in liquid nitrogen is the safest method of shipping for sperm preservation. The frozen semen the breeder is going to use may bе warmed immediately to body temperature. It should bе used soon after thawing because reduced fertility results from keeping thawed semen at 5°C for several hours before insemination.
