Description

Technical Field

[0001] The invention belongs to the technical field of white-feathered broiler breeding, and in particular relates to a grain-saving white-feathered broiler breeding method. Background Art

[0002] The broiler industry is the most large-scale, intelligent and intensive industry in China's livestock and poultry breeding industry. Thanks to standardized and unified management in the breeding process, as well as the timely introduction and application of new technologies, the industry has achieved significant growth in the past five years, with the output soaring from 4 billion to nearly 8 billion. The three-dimensional multi-layer cage technology has also developed rapidly during this period.

[0003] However, the industry is currently facing many problems. For example, the short intestine and rapid digestion characteristics of broilers lead to significant differences in the conversion rates of different feed ingredients. Therefore, in order to achieve rapid market release, farms usually provide broilers with high-energy and high-protein diets. This feeding plan will not only cause broilers to be overweight in the early stages of breeding, but will also cause an increase in diseases and mortality in the later stages of breeding, which will in turn lead to an increase in the amount of drugs used in farms. At the same time, excess nutrients will also be excreted with feces, causing multiple problems such as waste of resources and environmental pollution.

[0004] It can be seen that in the face of future food supply pressure, scarcity of breeding land, rising feed costs and other problems, developing a high-utilization and grain-saving breeding model is of great significance to improving my country's broiler production capacity and market competitiveness, as well as building an efficient, resource-saving and environmentally friendly modern broiler industry. Summary of the invention

[0005] The object of the present invention is to provide a grain-saving white-feather broiler breeding method, which combines chicken house environmental control, breeding management and nutritional supply to synergistically improve the growth potential of white-feather broilers, so as to achieve a white-feather broiler slaughter weight of 3kg at 40 days of age, a feed-to-meat ratio of 1.30-1.34:1, and a European efficiency index of more than 550; wherein the chicken house environmental control includes feeding temperature control, feeding humidity control, chicken house air quality standard control and chicken house lighting control; the breeding management includes feeding in a free-feeding manner with a clean trough and no feed control throughout the process; and the nutritional supply includes feeding granular feeds of different components and different particle sizes according to different ages.

[0006] The grain-saving breeding method provided by the present invention can not only shorten the time it takes to market chickens, but also save feed usage and reduce feces discharge, thereby establishing a large-scale efficient production model for caged white-feathered broiler chickens.

[0007] In a preferred embodiment, the feeding temperature control comprises:

[0008] 0-1 day old: the temperature of the chicken house is 34℃; 2-3 days old: the temperature of the chicken house decreases by 1℃ every day; 4-7 days old: the temperature of the chicken house decreases by 0.5℃ every day; 14-20 days old: the temperature of the chicken house is 28℃; 21-27 days old: the temperature of the chicken house is 26℃; 28-34 days old: the temperature of the chicken house is 24℃; 35-40 days old: the temperature of the chicken house is 21.5℃.

[0009] White-feathered broilers are warm-blooded animals without sweat glands. Their bodies are covered with feathers, and the heat generated in their bodies is mainly dissipated through breathing. The applicant discovered through experiments that in the free-feeding mode of clean troughs without feed control, chickens of different ages have obvious differences in their requirements for environmental temperature. Only at a suitable temperature can chickens stimulate their growth potential through free feeding. For example, for chickens of younger age, if the ambient temperature is low, the chickens' feed intake increases, and their growth is slow, more additional energy is needed to maintain body temperature rather than growth. For older chickens, if the ambient temperature reaches or exceeds 27°C, heat stress reactions will occur, manifested as decreased feed intake, increased water intake, and thinning feces; when the temperature reaches above 32°C, severe heat stress is likely to occur, with phenomena such as difficulty breathing, open-mouthed panting, increased body temperature, flushing of the crown and beard, cyanosis, etc., leading to large-scale deaths in a short period of time. Therefore, the present invention designs the aforementioned feeding temperature control standard.

[0010] In a preferred embodiment, the feeding humidity control comprises:

[0011] 1-7 days old: the humidity in the chicken house is 65%; 8-20 days old: the humidity in the chicken house is 60%; 21 days old to market: the humidity in the chicken house is 55%.

[0012] The humidity in the chicken house directly affects the health and growth of broilers, especially for the free-feeding feeding mode with clean troughs and no feed control. If the humidity is too high, it will be conducive to the development of pathogenic microorganisms and parasites, and coccidiosis, aspergillosis, etc. are prone to occur; the broiler's lungs absorb more water, which may lead to pulmonary edema and seriously affect the respiratory function. In addition, high humidity in the chicken house will also affect the heat dissipation of the chickens and reduce the activity of digestive enzymes, thereby reducing the digestibility of the diet. If the humidity is too low, a large amount of water in the chicken's body will be lost through breathing, the chicken will become dehydrated, and the amount of water consumed will increase, affecting normal digestion and absorption. Therefore, the present invention specifically designs the aforementioned feeding humidity control standard according to the full-time free-feeding feeding mode.

[0013] In a preferred embodiment, the chicken house air quality standard control includes:

[0014] From day 0 to slaughter, keep the oxygen in the chicken house >19.5%, carbon dioxide <4500ppm, carbon monoxide <10ppm, ammonia <10ppm, and dust <3.4mg / m 3 .

[0015] In a preferred embodiment, the chicken house lighting control includes:

[0016] The lights-off time is the local sunset time ± 0.5 hours, and the lights-off duration is N hours, and the correspondence between N and the age of the chickens is: 0-1 day old: N = 0; 2 days old: N = 1; 3-7 days old: N = 2; 8-35 days old: N = 4; 36-40 days old: N = 2.

[0017] In a preferred embodiment, the free feeding method without feed control in the clean trough specifically includes:

[0018] Day 0: 6 hours before the chicks enter the house, put 1 / 3 of the feed in the feed tray for pre-warming; 12 hours after the chicks enter the house, check the crop fullness to reach 85-90%, and 24 hours later, check again to reach 95-100%;

[0019] 1 day old: fill the feed pan to 1 / 2 again, and mix the feed in the feed trough every 4 hours to stimulate the chickens to eat;

[0020] 2 days old: fill the feed pan and mix the feed trough every 4 hours to stimulate the chickens to eat;

[0021] 3-7 days old: Take out the clean feed trays one by one, fill the feed trough with feed to a height of 2 cm, and mix the feed every 4 hours to stimulate the chickens to quickly adapt to the feed trough;

[0022] From 4 days old to ready for slaughter, feed the trough again after 1 hour, and then clean the trough again after 2 hours. Repeat this cycle until ready for slaughter.

[0023] In a preferred embodiment, when the lighting in the chicken house is controlled, if the feeding period conflicts with the lights-off time, the feeding will not be carried out.

[0024] During broiler breeding, turning off the lights in a dark environment can better promote the rest and development of chickens, stimulate the secretion of growth hormone in the chicken body, accelerate the growth of muscle and fat cells, promote the growth and development of broilers, improve the uniformity of the flock, reduce mortality, especially reduce the sudden death rate. The free feeding method combined with the clean trough and no feed control can increase the feeding speed of broilers, prompting the chickens to eat quickly in a short period of time until the crop is full of food and stop eating, breaking the traditional concept of "chickens eat for energy". Combining lights out with empty trough management can effectively regulate the metabolic balance of broilers, reduce cardiopulmonary pressure, promote the development of the immune system and gastrointestinal tract, improve the disease resistance and stress resistance of the flock, reduce maintenance energy consumption, and promote the chickens to fully utilize the daily diet in the digestive tract, thereby improving feed utilization, avoiding excessive feeding that causes the feed to be excreted without being fully digested and utilized, thereby significantly reducing the feed-to-meat ratio and improving the production efficiency of the enterprise.

[0054] The particle size and hardness of pellet feed have a great impact on the feeding speed and intake of broilers, and thus play an important role in the growth and development of broilers. Specifically, from the weight of a chick out of the shell of about 37g to 3kg at 40 days of age, if the feed is too hard and too large, it will be difficult for broilers to ingest it, the growth rate will be slow, and the food intake will be insufficient; if the feed is too soft and too small, the broilers will not chew it fully, which will affect the digestion and absorption of the gizzard and easily cause problems such as indigestion. Therefore, the scheme of the present invention reasonably designs the hardness and particle size of the feed according to the age and weight of the broilers and the free feeding mode of the whole process with clean trough and no feed control, which is crucial to reducing the feed-to-meat ratio of broilers.

[0055] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0056] In the breeding management, the present invention adopts a free-feeding method with a clean trough and no feed control throughout the whole process for feeding, and through the means of combining chicken house environment control, breeding management and nutrition supply, it effectively solves the problems of overweight in the early stage of broiler breeding, large dosage of drugs in the later stage of breeding but poor physique of broilers, which are common in the current white-feathered broiler industry. Moreover, although free-feeding and no feed control are adopted in the present invention, the feeding progress of broilers is improved by controlling the air, humidity, temperature and lighting in the chicken house environment, as well as a reasonable feeding mode and a combination of easy-to-eat granular feeds, and the nutrient acquisition of broilers is promoted, thereby synergistically improving the growth potential of white-feathered broilers and effectively reducing the mortality rate of large chickens in the meat stage.

[0057] By adopting the technical solution provided by the present invention, it is possible to achieve a white-feathered broiler chicken with a market weight of 3 kg at 40 days of age, a feed-to-meat ratio of 1.30-1.34:1, and a European efficiency index of more than 550; the breeding survival rate can reach more than 99%. The technical solution provided by the present invention has no feed change stress period and is particularly suitable for large-scale field application. DETAILED DESCRIPTION

[0113] Application Examples

[0114] 1. Test materials and methods:

[0115] 1.1 Test time and location:

[0116] The experimental time is from September 9 to October 18, 2024. The broilers are raised for 0-40 days and are slaughtered at 3 am at the age of 41 days.

[0117] Experimental location: Fuzhou town chicken farm, Wafangdian City, Liaoning Province.

[0118] 1.2 Experimental diet and experimental design:

[0119] The experimental animals were 13680 Cobb white broiler chickens, which were divided into 6 treatments, control groups 1, 2, 3 and experimental groups 1, 2, 3; each treatment had 2280 chickens.

[0120] Chicken house management: A three-layer cage-type closed chicken house is used, with 19 medium-sized meat chickens raised in each cage.

[0121] Among them, the control group 1 adopted the three-stage "pellet feed-powder feed-pellet feed", that is, the diet and feeding method of Example 1 in Patent No. CN201711096111.7;

[0122] Control group 2 adopted the three-stage "granular feed-powder feed-barreled pellet feed", that is, the diet and feeding method of Example 2 in patent number CN202111279948.1;

[0123] The control group 3 adopts the same diet and feeding environment control standards as Example 3 of the present invention, except that the control group 3 does not have an empty tank.

[0124] The diets of the experimental groups 1, 2 and 3 were respectively those of Examples 1, 2 and 3 of the present invention, and the feeding method was the free feeding method of the patent in a clean trough without feed control.

[0125] At 3:00 a.m. on an empty stomach, the broilers were slaughtered at 41 days of age. The total weight of each group was weighed when they were slaughtered.

[0126] 1.3 Determination indicators:

[0127] The weight of chicks entering the house, 24-hour crop fullness rate, number of deaths during the trial period, total weight of each group at market, and total feed intake were recorded, and the average weight of chicks entering the house, survival rate, feed-to-meat ratio, and European efficiency index were calculated.

[0128] 1.4 Data processing:

[0129] The experimental data were analyzed using EXEL.

[0130] Among them, the calculation formula of the European efficiency index is: [(body weight × survival rate) / (feed-to-meat ratio × age at market)] × 10000.

[0131] 2. Results and analysis, as shown in Table 5:

[0132] Table 5

[0133]

[0134]

[0135] Results and discussion: As can be seen from the above table, the application of the technology of the present invention can effectively reduce the feed-to-meat ratio and reduce the mortality rate, especially it can significantly reduce the number of sudden deaths of medium and large chickens, and the European benefit index can reach an average of 568. Moreover, the reduction of the feed-to-meat ratio can save feed costs and improve the economic benefits of the enterprise on the one hand, and can also reduce the amount of feces discharged on the other hand. For caged closed chicken houses, the reduction of feces discharge not only avoids environmental pollution in the chicken house, reduces the work intensity of workers, but also avoids the hidden danger of feces accumulation and increases broiler infection. According to calculations, the average amount of feces in the experimental group in the later stage of breeding was 150g / piece less than the average feces discharge of the control group. The production performance data of the experimental group is better, indicating that in the broiler breeding process provided by this scheme, the combination of chicken house environmental control, breeding management and nutrient supply can synergistically promote the development and growth potential of broilers. Therefore, the broiler breeding effect is significantly better than the existing technology.

[0136] In summary, the method provided by the present invention is particularly suitable for establishing standardized breeding in large-scale chicken farms, which can effectively reduce feed consumption, save energy, reduce costs and increase efficiency, and improve the production efficiency of breeding enterprises.
