Problems solved by technology

[0004] At present, 4 to 5 broods of eggs can be produced by artificial stimulation of oviposition, and the number of eggs can reach 30. However, the reproduction rate of black swans is still not large, which has caused the sales of black swans to be low, and the output of goslings is not high. It is difficult to meet the demand of the market, which is the main reason why the price of black swan has been high, which is the defect of existing technology

Embodiment 1

[0017] A preparation method for a feed additive for black swans, comprising the following steps:

[0018] 1. Select 120 parts by weight of fresh leaves of lacquer, 90 parts by weight of fresh petals of Budisma japonica, and 55 parts by weight of fresh leaves of sea milkweed, and dry them in an oven at a temperature of 60°C for 20 hours to obtain dried The leaves of lacquer, dried petals of Budisma buddha, and dried leaves of milkweed are ready for use. Those skilled in the art should know the drying process and equipment.

[0019] 2. Grind the dried lacquer leaves, dried Budisma petals, and dried sea milkweed leaves obtained in step 1 into powders, pass through a 50-mesh sieve, and mix evenly to obtain the feed additive for black swans.

[0020] Test results: The average number of eggs laid in No. 1 area was 42; the average number of eggs laid in No. 2 area was 43; the average number of eggs laid in No. 3 area was 40.

Select 143 parts by weight of fresh leaves of lacquer, 133 parts by weight of fresh petals of Budisma japonica, and 75 parts by weight of fresh leaves of sea milkweed, and dry them in an oven at a temperature of 60°C for 20 hours to obtain dried The leaves of lacquer, dried petals of Budisma buddha, and dried leaves of milkweed are ready for use. Those skilled in the art should know the drying process and equipment.

[0024] 2. Grind the dried lacquer leaves, dried Budisma petals, and dried sea milkweed leaves obtained in step 1 into powders, pass through a 50-mesh sieve, and mix evenly to obtain the feed additive for black swans.

[0025] Test results: The average number of eggs laid in No. 1 area was 41; the average number of eggs laid in No. 2 area was 39; the average number of eggs laid in No. 3 area was 42.

Embodiment 3

[0027] A preparation method for a feed additive for black swans, comprising the following steps:

[0028] 1. Select 132 parts by weight of fresh leaves of lacquer, 110 parts by weight of fresh petals of Budisma japonica, and 63 parts by weight of fresh leaves of sea milkweed, and dry them in an oven at a temperature of 60°C for 20 hours to obtain dried The leaves of lacquer, dried petals of Budisma buddha, and dried leaves of milkweed are ready for use. Those skilled in the art should know the drying process and equipment.

[0029] 2. Grind the dried lacquer leaves, dried Budisma petals, and dried sea milkweed leaves obtained in step 1 into powders, pass through a 50-mesh sieve, and mix evenly to obtain the feed additive for black swans.

[0030] Test results: The average number of eggs laid in No. 1 area was 45; the average number of eggs laid in No. 2 area was 43; the average number of eggs laid in No. 3 area was 44.

Abstract

The invention relates to a feed additive and particularly relates to feed additive for a black swan. The additive for the black swan is characterized in that the ingredients of the additive added to every 1000 parts by weight of basal feed and the weight proportion are as follows: 100-140 parts of sun euphorbia herb leaves, 210-250 parts of butterfly-bush flower pedals, and 45-63 parts of dried leaves of glaux maritima L. According to the feed additive, multiple nutrient elements are combined, the black swan acquires nutrients and microelements from the feed additive, the number of eggs laid by the black swan can be increased, and therefore, the efficiency and the yield of the artificially-fed black swan are improved.

Description

technical field [0001] The invention relates to a feed additive, in particular to a black swan feed additive and a preparation method thereof. Background technique [0002] The black swan (scientific name: Cygnusatratus) is a large swimming bird with a body length of 110-140 cm. Originally produced in Australia, it is an important member of the swan family and is a world-renowned ornamental rare bird. Black swans inhabit coasts, bays, lakes and other waters, and move in pairs or groups. Their food is almost entirely plants, various aquatic plants and algae. It is highly nomadic, with irregular migration patterns, mainly dependent on climatic conditions, and forms large groups of thousands when migrating. [0003] Black swans enter sexual maturity at the age of 20 months. Naturally hatched black swans can lay eggs after building a nest. Generally, the first egg is laid 8 to 15 days after the first mating, and one egg is laid every other day. Each nest can lay 6 eggs. ~7 pi...
