Problems solved by technology

[0005] Existing anti-heat stress products mainly increase the nutritional content of dairy cows’ rations by adjusting the rumen environment and adding nutrients, such as adjusting the rumen pH value, adding rumen fat or adding rumen amino acids to improve the nutrition in milk The purpose of the index, the effect of heat stress on dairy cows is not obvious

Embodiment 1

[0040] A summer heat stress feed for high-yielding dairy cows. The components of the heat stress feed include carriers, anti-stress factors, yeast substances, cations, tumor-passing amino acids, rumen-passing fat, organic trace elements, vitamins and rumen buffering agents.

[0041] The carrier is grain raw material granules, the anti-stress factor is a mixture of niacin and rumen-passed niacin, the yeast substance is yeast culture, the cation is potassium bicarbonate, the tumour-passed amino acid is rumen-passed methionine, and the rumen-passed fat is palm fat Powder, organic trace element is organic selenium, vitamin is vitamin E, rumen buffer is a mixture of magnesium oxide and baking soda.

[0042] The composition and mass fraction of heat stress feed are 41-55% of carrier, 13-16% of palm fat powder, 13-16% of yeast culture, 1-4% of magnesium oxide, 1-7% of baking soda, carbonic acid Potassium hydrogen 2-9%, 95% niacin 0.1-0.5%, rumen-passed niacin 0.1-0.5%, rumen-passed m...

Embodiment 2

[0054] The components and mass fractions of the heat stress feed are 53.9% of carrier, 15% of palm fat powder, 15% of yeast culture, 2% of magnesium oxide, 5% of baking soda, 7% of potassium bicarbonate, 0.3% of 95% niacin %, 0.3% rumen-passed niacin, 1% rumen-passed methionine, 0.3% organic selenium, and 0.2% vitamin E.

[0055] Therefore, the present invention adopts the above-mentioned high-yielding dairy cow summer heat stress feed, which can adjust the physiological environment of dairy cows in summer high-temperature and high-humidity seasons, reduce heat stress and respiratory rate, increase milk volume, and improve milk indicators.

Abstract

The present invention discloses a heat stress feed for high-yield dairy cows in summer. The heat stress feed comprises the following components: a carrier, an anti-stress factor, a yeast substance, acation, rumen-protected amino acid, rumen-protected fat, organic trace elements, vitamin and a rumen buffer. The heat stress feed for high-yield dairy cows in summer is adopted to regulate physiological environment of dairy cows in summer high-temperature and high-humidity season, thereby reducing stress, and breathing frequency, improving milk yield and improving milk index.

Description

technical field [0001] The invention relates to the technical field of anti-heat stress feed, in particular to a summer heat stress feed for high-yield dairy cows. Background technique [0002] The heat stress of dairy cows is a huge challenge faced by the dairy farming industry. Due to the underdeveloped sweat glands of dairy cows, long hair and thick skin, when the ambient temperature is high, it is difficult for the heat energy generated by metabolism in the body to diffuse to the environment through the body surface, thus It leads to a series of physiological changes in dairy cows, seriously affecting the physiological functions, physical health and production performance of dairy cows. [0003] When the environment exceeds 20°C, cows are likely to face heat stress. During heat stress, the dairy cows showed mouth breathing, abdominal breathing, significantly increased respiratory rate (under normal circumstances, the number of breaths per minute of dairy cows is 10-30 t...
