Simple method for enabling free-range cattle on grassland to breed twins

Abstract

The invention discloses a simple method for enabling free-range cattle on grassland to breed twins. The simple method comprises five aspects of cattle selection, feeding management, artificial induction of oestrus, hormone induction of ovulation and hybridization. Through control of the five aspects of cattle selection, feeding management, artificial induction of oestrus, hormone induction of ovulation and hybridization, free-range cattle can produce two denim at one time in the breeding process, and the breeding efficiency is improved.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a simple method for allowing cattle raised on grasslands to give birth to twins. Background technique [0002] Animal husbandry is the use of livestock and poultry and other animals that have been domesticated by humans, or the physiological functions of wild animals such as deer, musk deer, fox, mink, otter, quail, etc., through artificial feeding and breeding, so that they can transform the energy of plants such as pasture and feed It is the production department of livestock products such as meat, eggs, milk, wool, cashmere, hides, silk and medicinal materials for animals. [0003] But in existing animal husbandry breeding, mostly carry out natural breeding by livestock itself, and the majority that cattle produce by such breeding method is one litter, and reproductive efficiency is slower. Therefore, the present invention provides a kind of simple and easy method that allows ...

Problems solved by technology

[0003] However, in the existing animal husbandry, most of the natural reproduction is carried out by the livestock itself. Most of the cattle produced by this breeding method are one litter, and the reproductive efficiency is relatively slow.
