A kind of feeding method of laying chicken
Technical field
The present invention relates to a kind of feeding method of laying chicken, specifically a kind of feed formula is by the feeding method of laying chicken 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 feed intake is different in different seasons does not meet the nutrient requirement of laying hen.Summer easily occurs nutrition (particularly albumen and calcium, amino acid) deficiency, 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 to design different suggested formula according to Various Seasonal, so that laying hen nutrition is balanced, it is stable that laying rate keeps.
Summary of the invention
The present invention provides a kind of feeding method of laying chicken for overcoming above-mentioned the deficiencies in the prior art, and by the classification in season, thereby being held time in the Egg Production of Laying Hens peak grows, feedstuff-egg ratio is low.
The objective of the invention is to be achieved through the following technical solutions:
A kind of feeding method of laying chicken, 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 the gram/pcs/day, spring, autumn by 120 grams/pcs/day, winter by 130 the gram/pcs/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 comprised of corn, dregs of beans, stone flour, laying hen premix, oil.
The present invention designs different suggested formula through for many years practice 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 present invention to the feeding effect of layer chicken, company technique section has carried out by a definite date 270 days feeding experiment 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 quarterly classification.
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 the impact of commercially available similar feed on performance in layers of the feeding the inventive method design of table 1
