Technical Field
The invention belongs to the technical field of cultivation, and particularly relates to a method for improving the laying rate of laying hens.
Background
The eggs have high nutritional value, are one of the foods which are usually eaten by human beings, and have wide market application. How to improve the egg yield of laying hens is the focus of attention of farmers. In recent years, various methods have been sought for increasing the laying rate of laying hens. However, many methods only emphasize short-term benefits, greatly stimulate the bodies of the laying hens, obviously reduce the immunity of the laying hens, obviously reduce the egg laying period and reduce the quality of eggs.
On the other hand, with the rapid development of agricultural industry in China, the vegetable planting scale is greatly increased, a large amount of fruit and vegetable byproducts such as vines, fruit peels and other wastes exist every year, the byproducts contain abundant nutrients and available chemical components, the utilization value is high, but a large amount of vegetable byproducts are randomly discarded and stacked, so that not only is the resource waste caused, but also the soil, water, air and the like are greatly polluted. In recent years, there have been reports of the use of silage for cattle and sheep, but the use of silage for chicken breeding has been less. If the fruit and vegetable wastes can be used for raising laying hens, the yield and the quality of eggs are improved, the problem of environmental pollution in rural areas can be solved, and the ecological cycle of agricultural production is facilitated.

Test examples
750 laying hens with good health condition and 150 days old are selected and randomly divided into 4 groups, the 4 groups are respectively a control group and the groups of examples 1-3, each group is provided with 3 repeated treatments, and each repeated group is provided with 50 laying hens for cage culture. The control group was fed with normal daily ration, the groups of examples 1-3 were fed with the feeds of examples 1-3, respectively, and the group of comparative example 1 was fed with the feed of comparative example 3. Feeding for 1 time at 9:00 and 16:30 times a day, and keeping the rest according to conventional animal feeding management. After 40 days of feeding, the laying hens enter a stable egg laying period, and the production performance, egg laying quality, egg nutritional ingredients and egg yolk antioxidant indexes of the laying hens are tested for 30 days.
The production performance is as follows: during the test period, eggs are picked up at 8:30 and 16:00 days, and after the test is finished, the egg yield, the laying rate, the egg weight and the feed-egg ratio are counted.
Egg quality: at the end of the experiment, 3 egg samples were randomly taken per repetition, and the yolk ratio, shell thickness, shell strength, yolk color and egg shape index were measured and averaged.
The nutrient components of the eggs are as follows: 4 egg samples were randomly sampled for each replicate in the control, comparative 1 and example 2 groups, respectively.
The oxidation resistance index of the eggs is as follows: after the test is finished, 6 egg samples are randomly taken in each repetition, and the content of Malondialdehyde (MDA) and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) are detected. Adding equal amount of physiological saline into yolk, mixing, extracting for 2min, centrifuging at 3000r/min for 10min, collecting supernatant, and determining GSH-Px activity with kit; the supernatant was diluted with physiological saline at a ratio of 1:4, and 0.05mL of the sample was taken to determine SOD activity using a kit. Sucking yolk, adding 9 times of anhydrous ethanol, mixing uniformly, extracting for 3min, centrifuging at 4000r/min for 10min, collecting supernatant 0.2mL, and detecting MDA content with kit.
And (3) test results: table 1 shows the laying performance data of the layers, and it can be seen that the laying rate of the example group is higher than that of the control group; compared with a control group, the laying rate of the example group is obviously improved, the soft egg breaking rate and the feed-egg ratio are obviously reduced, and the feed-egg ratio is further reduced, which shows that the laying performance of the laying hens can be effectively improved by feeding the laying hens with the feed.
