Embodiment

[0019] The basal diet in this application is a corn-soybean meal type basal ration, wherein the addition amount of corn and soybean meal is 2:1, shell meal is 5%, soybean oil is 3%, fish meal is 2%, and premix is ​​3%. The feed of the experimental group was the mixed diet corresponding to the ratio of microalgae and basal feed for each group. The feedstuffs are purchased by professional feeders, and the feedstuffs are regularly mixed to prepare the feedstuffs.

[0020] The premix provides per kilogram of feed: VA-8000IU, VB1-4mg, VB 2 -3.6mg, VB 5 -40mg, VB 6 -4mg, VB 12 0.02mg, VD 3 -3000IU, VE-20IU, D-pantothenic acid-11mg, VK 3 -20mg, Biotin-0.15mg, Folic Acid-1.1mg, Antioxidant-100mg, Niacin-10mg, Cu-10mg, Fe-80mg, Mn-80mg, Zn-75mg, I-0.40mg, Se0.30mg.

[0021] The laying hens in this application are Ross laying hens, 30 weeks old, 48, egg production rate 85%.

Abstract

The invention belongs to the technical field of alga culture, and in particular discloses a method for preparing high-nutrient eggs through adding formula microalgae into chicken feed. The method comprises the following steps: (1) preparing algae into dry alga powder; (2) feeding laying hens with mixed feed containing basic feed and the alga powder, and taking eggs for two times every day; recording the daily intake amount, laying rate and feed-gain ratio of the laying hens and the average egg weight of the eggs; (3) separating egg white from yolk of the eggs; comparing the chroma of the yolk,determining the content of total fatty acid in the yolk and calculating a yolk ratio and the ratio of PUFAs (Polyunsaturated Fatty Acids) in the total fatty acid in the yolk. The eggs produced by themethod have relatively high content of the fatty acid and relatively high nutrients.

Description

technical field [0001] The invention belongs to the technical field of algae cultivation, and specifically discloses a method for adding formula microalgae to chicken feed to prepare high-nutrition eggs. Background technique [0002] Fatty acids are long aliphatic hydrocarbon chains, and different types of fatty acids vary in length, degree of saturation, and structure. Compared with saturated fatty acids and monounsaturated fatty acids, polyunsaturated fatty acids (PUFAs) containing two or more unsaturated bonds have more important physiological effects on the body. [0003] PUFAs are mainly divided into ω-3 series fatty acids and ω-6 series fatty acids. Among them, the double bond farthest from the carboxyl group of the hydroxyl chain is at the penultimate third, and the 4 carbon atoms are ω-3 series fatty acids. The double bond at the farthest end of the carboxyl group of the oxygen chain is between the penultimate 6th and 7th carbon atoms, which are omega-6 series fatty...
