Description

Technical Field

[0001] The present invention relates to the technical field of poultry breeding, and in particular to a method for breeding laying fowl throughout their life cycle. Background Art

[0002] Egg-laying poultry refers to poultry that is raised together to supply commercial eggs. China is the world's largest egg-laying poultry breeding country, with poultry egg production reaching 40% of the global production. The egg-laying poultry industry is very large, but the genetic potential of egg-laying poultry has not been fully utilized. Most egg-laying poultry are now eliminated after about 500 days. If they continue to be fed, the egg production rate will drop below 80%, and the efficiency will decline. The production cycle of egg-laying poultry can last for about 700 days. Therefore, the clinical production cycle of egg-laying poultry does not reach the genetic potential. Take the commonly raised high-yield egg-laying chickens as an example. In a cycle of 500 days, the average number of eggs laid is less than 300; while the genetic potential can actually reach 350, so the egg production does not reach the genetic potential.

[0003] This has led to the fact that although the egg-laying poultry industry in our country has a large breeding volume, the output has not been maximized, and there is still a gap of about 20% between the actual production performance and genetic potential. In terms of exerting genetic potential, we still have a lot of room for improvement. Therefore, it is necessary to conduct an in-depth analysis of the entire life cycle of egg-laying poultry, find the key stages to improve production performance, and fundamentally solve the problem of high-quality production and increased income. Summary of the invention

[0004] The present invention provides a method for breeding laying fowls throughout their entire life cycle, thereby solving the problem of low egg production in laying fowls in the related art.

[0019] The working principle and beneficial effects of the present invention are:

[0020] 1. The present invention divides the feed of laying poultry into four stages. Through the breeding method of laying poultry throughout its life cycle, the genetic potential of laying poultry is fully utilized. The egg production of laying poultry is 327-345 eggs per poultry, and the egg-laying cycle is greater than 660 days, thereby achieving the purpose of high yield and increased income.

[0021] 2. In the first stage, calcium gluconate, L-lysine, taurine, zinc gluconate, B vitamins, psoralea corylifolia extract, and oyster extract are added to the feed when the laying hens are 7, 21, and 60 days old. The purpose is to activate the potential for bone development on the basis of reaching the weight standard, lay the foundation for "35 days of age for life", and at the same time, expand the pubic width during the rearing period, increase the bone calcium reserve, reduce the problems of new hens, and prepare for smooth production and high and stable production.

[0022] 3. In the second stage, when the laying poultry is 80 days old, 105 days old, 140 days old, and 155 days old, add vitamin A, vitamin D3, vitamin E, methionine, lysine, and marigold extract to the feed for 5 consecutive days. Among them, 80 days old: lay a good foundation for the development of ovaries and oviducts, 80 days old to determine high production, and provide source power for high production; 105 days old: promote the rapid development of ovaries and oviducts, reserve power for climbing up the peak quickly, and avoid new hen disease; around 140 days old: reserve power for the follicle development to reach the peak, so that the peak is higher. 155 days old: stimulate the reproductive system, prevent egg-laying fatigue, and make the peak longer.

[0023] 4. The third stage, 350-550 days of age, is a critical period when egg production and egg quality decline. Add selenium-rich vitamin E, methionine, calcitonin, marigold extract, epimedium extract, motherwort extract, and Ligustrum lucidum extract to the feed for 5 consecutive days each month to maintain the peak egg production to 550 days of age.

[0024] 5. In the fourth stage, from 20 days before the egg-laying poultry is eliminated to the time it is slaughtered, add L-lysine, zinc propionate, capsaicin, hawthorn extract, and malt extract to the feed to make the eliminated egg-laying poultry grow fatter and stronger. DETAILED DESCRIPTION

[0087] Test example

[0088] The eggs were cultured according to the culture methods of Examples 1-4 and Comparative Examples 1-5, and a control group was set up to measure the egg production. The measurement results are shown in Table 1.

[0089] Experimental Design:

[0090] 1500 5-day-old active, healthy laying hens of uniform size were selected for breeding. The breed was Jingbai 938 laying hens. They were randomly divided into 10 groups, with 5 replicates in each group and 30 hens in each group. They were pre-fed for two days and then culled out.

[0091] The preparation method of the pre-feeding feed is as follows:

[0092] A1. Evenly mix 0.15 kg of complex amino acids, 0.06 kg of complex vitamins, and 0.01 kg of complex trace elements to obtain a premix;

[0094] Trial Management:

[0095] The test site is a farm in Shangzhuang Town, Luquan District, Shijiazhuang. Three-layer stepped cages are used. The chicken house is cleaned and disinfected before the test. Natural light is used from 07:30 to 17:30 every day, and light is used to supplement the light at other times. The supplementary light time is 17:30-19:30, 0.00-01:00, and 04:30-07:30. Feed and drink water freely. Feed once at 8:00, 11:30, and 17:30 every day. Keep the growth environment of laying hens clean and tidy, disinfect regularly, and prevent diseases normally. Collect eggs at 10:30 am every day and count the number of eggs laid (within the production cycle).

[0096] Egg production (eggs / hen) = total number of eggs / total number of laying hens

[0097] Table 1 Measurement results

[0098] Egg production (pieces / egg) Example 1 337 Example 2 344 Example 3 333 Example 4 345 Control group 260 Comparative Example 1 316 Comparative Example 2 322 Comparative Example 3 325 Comparative Example 4 320 Comparative Example 5 302

[0099] Compared with Example 1, in the first stage of Comparative Example 1, no psoralea extract and oyster extract were added, in the first stage of Comparative Example 2, no psoralea extract was added, in the first stage of Comparative Example 3, no oyster extract was added, and in the first stage of Comparative Example 5, only psoralea extract and oyster extract were added. As shown in Table 1, the egg production of the breeding methods of Comparative Examples 1-3 and Comparative Example 5 was lower than that of Example 1, and the feed-egg ratio was higher than that of Example 1. This indicates that the egg production of laying hens can be increased by adding the first additive in the first stage.

[0100] Compared with Example 1, Comparative Example 4 increases the addition time of the first feed additive. Through the breeding method of Comparative Example 4, the statistical egg production is lower than that of Example 1, indicating that increasing the addition time of the first additive will not improve the breeding effect.

[0101] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
