A kind of layer breeding method
Technical field
The present invention relates to a kind of layer breeding method, specifically a kind of feed formula is by the layer breeding method of classification in season.
Background technology
Current egg feedstuff product is divided into premix, complete diet pellet, concentrate feed.The suggested formula of premix product generally only designs one, and the nutrition that causes laying hen to eat into because of feed intake is different in different seasons does not meet the nutrient requirement of laying hen.Occur nutrition (particularly albumen and calcium, amino acid) deficiency summer easily, cause laying rate of laying hen decline, eggshell quality variation.Be prone to overnutrition winter, cause that egg size is excessive, prolapse of the anus, death rate rise.For this reason, when laying hen is improved the feeding and management level, need design different suggested formula according to Various Seasonal, so that the laying hen nutrition equilibrium, it is stable that laying rate keeps.
Summary of the invention
The present invention provides a kind of layer breeding method for overcoming above-mentioned the deficiencies in the prior art, by season classification, thereby make laying hen lay eggs the peak hold time long, feedstuff-egg ratio is low.
The objective of the invention is to be achieved through the following technical solutions:
A kind of layer breeding method, with laying cycle of laying hens complete diet pellet nutritive index by every day laying hen energy 320 kilocalories, thick protein 18 grams, methionine 460-470 milligram, calcium 4 grams of need searching for food design, according to the feed intake of Various Seasonal different be summer feed intake by 110 grams/only/day, spring, autumn by 120 grams/only/day, winter by 130 grams/only/day, different according to feed intake, calculate the content of thick protein, methionine, calcium in the food that needs every laying hen every day, thereby design the prescription of the egg feedstuff of Various Seasonal according to the nutritive index of feedstuff.
Described feedstuff is made up of corn, dregs of beans, stone flour, laying hen premix, oil.
The present invention designs different suggested formula through practice for many years by Various Seasonal, produces to have the feed that improves egg laying performance, feeds layer chicken with this feed, can make the laying rate of layer chicken keep more than 8 months feedstuff-egg ratio about 2.0 rush hour.
In order to verify the feeding effect of the present invention to layer chicken, technology department of company has carried out 270 days feeding experiment by a definite date in the 4-12 month in 2009 in raiser laying hen field.Single factor comparative trial design is adopted in test, and a healthy layer chicken about 10000 180 ages in days is divided into experimental group and control group at random, and every group comprises 3 repetitions.The experimental group daily ration designs by the four seasons for the layer chicken feed by the inventive method design, prescription, and the control group daily ration is commercial like product and not classification quarterly.
Result of the test shows: 1, death rate: experimental group has reduced by 2.13% than control group; 2, laying rate: experimental group has improved 7.92% than control group; 3, average egg weight: experimental group has improved 0.51 gram than control group; 4, rate of broken eggs: experimental group has reduced by 0.28% than control group; 5, feedstuff-egg ratio: experimental group has reduced by 0.15 than control group.
The feed and of the influence of commercially available similar feed of the feeding the inventive method design of table 1 to the laying hen productivity
