Abstract

The invention discloses a raising method for poultry in the egg producing period. The total fodder amount of feeding fodder for a poultry group every day is determined according to the egg weight and the egg laying rate, wherein the everyday total fodder amount (kg)=(the everyday egg laying rate*100+an egg weight corresponding constant+/-5)*the number of ducks on hand on that day/1000; the egg laying fodder of the breeding ducks meets the following nutrient condition and comprises 16%-18% of crude protein (by weight), 1750-2650 KC of poultry metabolic energy, 3.0%-3.2% of calcium (by weight) and 0.45%-0.5% of available phosphorus (by weight). Accordingly, the everyday fodder amount and the supervision range are set, the life and normal physiological sustaining need of large breeding muscovy ducks can be met, the egg laying need of the breeding muscovy ducks can also be met, the production result is ideal, and unnecessary fodder waste can be reduced.

Description

A kind of laying period kind duck raising method

Technical field

The present invention relates to poultry cultivating technology, be specifically related to plant in a kind of laying period the cultural method of duck.

Background technology

Feed accounts for 70% of seedling production cost.The number of material amount directly has influence on the height of kind of the performance of duck egg laying performance and duck field effectiveness of operation.For a long time, our kind kind duck laying period materials are generally to feed a meal morning, material amount how much one week by rule of thumb calmly once, with duck free choice feeding to certain hour and determining in afternoon.Following table is materials amount and the laying rate data of 4 groups of certain duck field macrospecies kind ducks of selective examination:

Table 1 macrospecies kind duck laying period materials amount and laying rate selective examination table

As can be seen from Table 1:

1. there is the randomness of materials in the duck group that this difference is laid eggs age in week, every day, the accuracy of materials amount was inconsistent, sometimes differs greatly, exist or material amount too many, cause certain waste, or material amount is on the low side, affect the problem such as performance of duck group egg laying performance.

2. only feed the way of a meal feed every day, laying ducks appetite is not too strong, affects some laying duckses regular burden(ing) amount of searching for food.

3,, according to the dietary habit of kind of duck, lay eggs duck poor and search for food the morning and be more, and the duck of laying eggs searches for food more afternoon.If only feed a meal, arrive dusk material amount afternoon less or nothing, will affect the feed intake of outstanding duck; Feed the way of two meal every day and adopt, the material amount in afternoon can meet lay heavily duck searches for food, thereby balance the superior eats more, and the inferior eats less.

4,, as production manager, lack relatively accurate quantification supervision foundation.

Summary of the invention

The present invention is intended to address the above problem to a certain extent, and a kind of coml application is at least provided.

For this reason, goal of the invention of the present invention is to overcome the defect of prior art, provides a kind of science to raise the method for poultry in laying period.

For achieving the above object, the present invention adopts following technical scheme, and the raising method of poultry in a kind of laying period determines that according to egg size and laying rate the total stuff amount of group of birds feeding feed stuff every day is:

Total stuff amount on the same day (kg)=(corresponding constant ± 5 of laying rate * 100+ egg size on the same day) * livestock on hand on same day duck number/1000;

And this kind of duck feed of laying eggs meets following nutrient condition:

The content of crude protein is 16-18(weight) %, fowl metabolic energy is 1750-2650KC, calcium content is 3.0-3.2(weight) %, and can utilize phosphorus content for 0.45-0.5(weight) %.

Be set as materials amount and supervision scope on the same day with this, both can have met that a macrospecies kind duck sustains life and normal physiological needs, can meet again kind of kind duck needs of laying eggs, production achievement is more satisfactory, and can reduce unnecessary feed waste.

Particularly, divide two meal to feed whole day feed total amount, upper lunch is fed 40% of whole day material amount, and lower lunch is fed 60% of whole day material amount.

Particularly, the corresponding constant of described material amount is determined by following egg size scope:

Average egg weight is at 73-79 gram, and the corresponding constant of egg size is 80;

Average egg weight is at 80-84 gram, and the corresponding constant of egg size is 90;

Average egg weight is at 85-90 gram, and the corresponding constant of egg size is 100.

Particularly, described kind of duck is that macrospecies kind duck, cherry are chosen seed-grain duck.

Beneficial effect of the present invention, the egg size of laying eggs age in week according to difference, be set as materials amount on the same day (kg) by " (corresponding constant ± 5 of laying rate * 100+ egg size) * livestock on hand duck number/1000 ", adopt feed the way of two meal every day, duck group laying rate is not caused extremely.Technical staff is no longer for fixed material takes too many brains, poultry raiser can quantize to determine material factually time by actual egg number on the same day voluntarily, reduced empirical way and the subjective deviation on materials, ensure that kind of a kind duck sustains life and normal physiological with lay eggs and need outside, can also effectively save feed.

Embodiment

Describe the present invention below in detail as an example of kind duck in laying period example.

Taking conventional laying ducks feed as feedstuff feeding.

Table 2, by the inventive method two groups of kinds of ducks of feeding

Table 3: standard laying rate

In the macrospecies kind duck of table 2 for the section in age in week of laying eggs two groups of differences, carry out the checking of month by a definite date.By the standard laying rate comparison of experimental result and table 3, result of the test shows, according to difference lay eggs week age egg size, be set as materials amount on the same day (kg) by " (laying rate * 100+ constant ± 5) * livestock on hand duck number/1000 ", adopt and feed the way of two meal every day, duck group laying rate is not caused extremely to (note: the index of laying eggs is to evaluate whether normal, the good and bad important evidence of productivity of duck group laying rate, the index of laying eggs=actual laying rate/standard laying rate in large production.In the time that the index of laying eggs is more than or equal to 1, illustrate and lay eggs normally, otherwise abnormal).Adopt after the technical program, technical staff is no longer for fixed material takes too many brains, poultry raiser can quantize to determine material factually time by actual egg number on the same day voluntarily, has reduced empirical way and the subjective deviation on materials, ensure that kind of a kind duck sustains life and normal physiological with lay eggs and need outside, save feed 11.3g average every every day, lay eggs 26 weeks with every duck, the 3.5 yuan/kg of material list valency that lays eggs counting, can save 7.2 yuan of feed costs, and laying rate improves, and effect is remarkable.

Claims

Laying period kind duck a raising method, it is characterized in that,
