Embodiment 1

[0010] Embodiment 1, for Hu sheep

[0011] A Hu sheep weighs 15kg. Take 15 grams of tea seed cake (meal) and mix it with other feed of Hu sheep every day, and feed it twice in the morning and evening, which can improve the utilization efficiency of feed for Hu sheep and promote the growth of Hu sheep.

Embodiment 2

[0012] Example 2, for goats

[0013] For a goat weighing 15kg, take 2 grams of tea saponin and mix it with other feed for Hu goats every day, and feed it twice in the morning and evening, which can improve the utilization efficiency of the goats’ feed and promote the growth of goats.

Embodiment 3

[0014] Embodiment 3, for beef cattle

[0015] For a beef cattle weighing 200kg, take 200 grams of tea seed cake (meal) and mix it with other feed for beef cattle every day, and feed it twice in the morning and evening, which can improve the utilization efficiency of feed for beef cattle and promote the growth of beef cattle.

Abstract

The invention discloses a use of tea seed cake and dregs or its extract--tea saponin, used for regulating and control rumen fermentation of ruminants: the added quantity in daily food of ruminants: (1) adding in the cake and dregs at 0.05-7.00g per kg body weigh every day; (2) adding in the tea saponin at 0.01-0.70g per kg body weight every day. When adding at low added quantity, inhibit and kill partial protozoa in the rumen and when adding at high added quantity, inhibit and kill all the protozoa in the rumen; with the increase of added quantity, the output of volatile fatty acid and microbe protein increases, the proportion of propionic acid is increased, the output of ammoniacal nitrogen and methane as well as the number methane bacteria are reduced, and the feed utilization ratio is increased, and the quantity of daily weight increase of the animal is increased. It reduces the breeding cost and improves breeding benefits.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to the use of tea seed cake or its extract tea saponin. Background technique [0002] Tea saponin (theasaponin) is a saponin component present in tea seeds and tea leaves. Tea saponin was originally used only as a natural emulsifier. In the past 20 years, there has been a lot of research on the development and research of the surface activity and pharmacological effects of tea saponin. With great progress, it is widely used in construction, chemical, pharmaceutical and other industries. Tea saponin is a toxic and harmful substance for animals, which has a negative effect on animal growth. Therefore, when tea seed cake (meal) is used for monogastric animals such as pigs and chickens, it is necessary to remove tea saponin. However, adding an appropriate amount of tea seed cake (meal) or tea saponin to ruminant feed can regulate the rumen fermentation of ruminants and promote animal growt...
