Embodiment 1

[0034] The invention utilizes technologies such as emulsification, shearing, homogenization, enzymatic hydrolysis, and microcapsule coating to process various oils and fats, and develops traditional single liquid oils into high digestibility and balanced fatty acid, which can improve feed utilization and reduce egg dark spots , and improve the complex powdered oil of egg protein components, such as figure 1 As shown, the detailed preparation method is as follows:

[0035] (1) A mixture of various vegetable oils

[0036] The fat in this embodiment mainly includes mixed oil and puffed corn, and the mass ratio thereof is 5:4.5. After calculating the fatty acid content in various raw material oils, various vegetable oils are mixed in a certain proportion. In parts by weight, the mixed oil is composed of 8 parts of sunflower oil, 7 parts of sesame oil, 15 parts of rapeseed oil, and 10 parts of palm oil. , 40 parts of corn oil, 10 parts of linseed oil, and 10 parts of soybean oil....

Embodiment 2

[0049] 1 Materials and methods

[0050] 1.1 Experimental materials and feeding management

[0051] Select 1,350 Nongda No. 5 parent laying hens with the same physical condition and production performance, and divide them into control group (containing 0.5% soybean oil), treatment group I (containing 1% balanced oil), and treatment group II (containing 1.5% balanced oil) , 450 rats in each group, and 6 repetitions in each group. The feeding period was 5 weeks.

[0052] Here, the dosage of the control group and the treatment group is determined according to the total metabolic energy, and the original feed is conventional chicken feed, which contains ingredients such as corn, soybean meal, stone powder and premix. Since the metabolizable energy of soybean oil is higher than that of balanced oil, adding the same amount of soybean oil and metabolized oil will result in different metabolic energy of the feed, which is difficult to compare. Therefore, more metabolized oil is used ...

Embodiment 3

[0063] 1 Materials and methods

[0064] 1.1 Experimental materials and feeding management

[0065] 324 Hebei Rongde Poultry Breeding Co., Ltd. in good health and similar production performance of 412-day-old "Nongda No. 3" laying hens were selected for the test. They were randomly divided into 2 groups (control group and test group), with 6 replicates in each group and 27 laying hens in each replicate, which were raised in the same environment. The control group was fed a conventional diet containing 1.5% soybean oil. In order to keep the metabolic energy of the two groups of diets consistent, 1.85% balanced oil was used to replace the soybean oil in the conventional diet for the experimental group. The test period is 35 days, and the pre-trial period is 7 days.

[0066] The amount of soybean oil and balanced oil used here is the same as in Example 2. In order to keep the total energy of feed metabolism of the control group and the test group the same, different mass ratios ...

Abstract

The invention relates to an oil meal composition for chicken feed as well as a preparation method and application of the oil meal composition. The oil meal composition comprises 6-9 parts of sunflower seed oil, 6-9 parts of sesame oil, 8-12 parts of palm oil, 35-45 parts of corn oil, 8-12 parts of soybean oil, 12-18 parts of rapeseed oil, 8-12 parts of linseed oil and 80-100 parts of puffed corn. According to the composition characteristics of different vegetable fat fatty acids and the difference of fatty acid nutritional requirements of laying hens, different natural vegetable oils are subjected to scientific proportioning, ultramicro shearing, enzyme digestion exchange and efficient emulsification refining, lysolecithin is coated on the surfaces of oil drops, and balanced fat more suitable for chicken feed is obtained; the effective feed utilization rate and the laying hen hatching rate can be improved; the dark spot egg rate is reduced by 60% or above, and the Hardgrove unit of eggs and the freshness of the eggs are improved; the oil powder composition provided by the invention is rich in medium-chain fatty acid, improves the immunity, reduces the occurrence of digestive tract diseases, and realizes'antibiotic-free breeding '.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to an oil powder composition for chicken feed and a preparation method and application thereof. Background technique [0002] Egg dark spots refer to watermark-like spots on the surface of egg shells, which become more and more obvious as the storage time of eggs prolongs. Dark spots are formed under the interaction of egg contents, eggshell structure, and external environment. There are many reasons for their formation, such as local secretion abnormalities due to inflammation of the uterine mucosa, abnormal substance deposition, formation of dark spot eggshells or moldy Cause dark spots etc. Eggs with more dark spots are more likely to be contaminated with Salmonella, making the egg content easily contaminated and causing food safety hazards. At the same time, the higher the coverage of dark spots on the surface of the eggshell, the faster the freshness of the egg decreased during...
