Novel feed for feeding milk cows and feeding method of milk cows

Abstract

The invention provides a novel feed for feeding milk cows and a feeding method of milk cows. Biogas slurry is used as a feed additive and is mixed into concentrated feed for feeding the milk cows, after the biogas slurry is taken out from a methane tank, solid matters in the biogas slurry are removed through precipitation, the precipitated biogas slurry is filtered by gauze, and the filter liquid is placed for 2 to 3 hours. In the adult cow breeding stage, the cows are fed for three times in each day, and 0.5 percent to 0.6 percent of biogas slurry is added into the concentrated feed fed in each time and is uniformly stirred to be supplied to the milk cows to eat; in the milk production stage, the cows are fed for three times in each day, and 1 percent to 2 percent of biogas slurry is added into the concentrated feed fed in each time and is uniformly stirred to be supplied to the milk cows to eat; in during the milk cow empathema and pregnancy periods, the concentrated feed mixed with the biogas slurry cannot be fed for the milk cows. The novel feed and the feeding method have the advantages that the biogas slurry is used as the feed additive and is mixed into the concentrated feed of the milk cows, amino acid, vitamins and the like necessary for the milk cow growth and rich mineral substances and protein contained in the biogas slurry are utilized, the milk cow growth is promoted, the immunity of the milk cows is improved, the milk yield is improved, and the goal of increasing the economic income is reached.

Description

technical field [0001] The invention belongs to the technical field of poultry feeding, and in particular relates to a new feed for raising dairy cows and a feeding method thereof. Background technique [0002] At present, the dairy cows are mainly raised with roughage and concentrated feed. Dairy cows are relatively delicate breeds, especially in the growth period and milk production period. The quality of the feed directly affects the development and milk production of dairy cows. The price of traditional concentrated feed is high. Dairy cows have a large feed intake. An adult cow consumes about 7-9 kg of concentrated feed and 30 kg of roughage per day during the milk production period to produce about 25-30 kg of milk, which makes the breeding cost of the farm remain high. Therefore, there are It is necessary to improve the feeding method, further reduce the feed cost, and increase the feed remuneration, so as to improve the economic benefits of raising dairy cows. Cont...
