Problems solved by technology

Since the utilization rate of vitamin A added in the diet is greatly affected by the content of carotene in the diet, if the content of carotene in the feed is not considered, it is impossible to determine the amount of vitamin A that beef cattle can actually obtain
At home and abroad, there is no report on the impact of vitamin A on beef marbling grade, intramuscular fat content and other indicators of beef through regulating the content of vitamin A and carotene in feed. Patent for improving intramuscular fat content and improving marbling grade without affecting the health of beef cattle

Embodiment 1

[0018] In a beef cattle farm, 16 12-month-old Limousin-Luxi cattle crossbreed steers with a weight of about 350 kg were selected, and they were divided into Invention Diet 1, Invention Diet 2 and Common Diet according to random block design. Three groups, the diet composition is shown in Table 1. The amount of vitamin A added to the feed of group 1 of the inventive diet was 0, the amount of vitamin A added to the feed of group 2 of the invented diet was 1100 international units per kilogram of dry matter of the feed, and the normal diet group was added according to the nutritional standard. The amount of feed was fed according to 2.3% of body weight. The test cows were fed alone in a single trough, and were fed at 8:00 am and 4:00 pm every day, and had free access to water. Feed for 90 days and then slaughter. During the 90-day test period, the test cows in each group had normal feed intake and weight gain, and showed no adverse health conditions. The intramuscular fat cont...

Embodiment 2

[0022] In a beef cattle farm, 16 12-month-old Limousin and Luxi Yellow Cattle hybrids with a weight of about 330 kg were selected, and they were divided into Invention Diet 1, Invention Diet 2 and Common Diet according to random block design. Three groups, the diet composition is shown in Table 1. The amount of vitamin A added to the feed of group 1 of the inventive diet was 0, the amount of vitamin A added to the feed of group 2 of the invented diet was 1100 international units per kilogram of dry matter of the feed, and the normal diet group was added according to the nutritional standard. The amount of feed was fed according to 2.3% of body weight. The test cows were fed alone in a single trough, and were fed at 8:00 am and 4:00 pm every day, and had free access to water. Feed for 180 days and then slaughter. During the 180-day test period, the feed intake and weight gain of the test cows in each group were normal, but the test cows in group 1 of the invented diet showed ...

Embodiment 3

[0026] In a beef cattle farm, 16 Limousin and Luxi yellow cattle crossbreeding first generation steers aged 24 months and weighing about 450 kg were selected and divided into invention diet 1, invention diet 2 and common diet according to random block design Three groups, the diet composition is shown in Table 1. The amount of vitamin A added to the feed of group 1 of the inventive diet was 0, the amount of vitamin A added to the feed of group 2 of the invented diet was 1100 international units per kilogram of dry matter of the feed, and the normal diet group was added according to the nutritional standard. The amount of feed was fed according to 2.3% of body weight. The test cows were fed alone in a single trough, and were fed at 8:00 am and 4:00 pm every day, and had free access to water. Feed for 90 days and then slaughter. During the 90-day test period, the feed intake and weight gain of the test cattle in each group were normal. Compared with the ordinary diet, the inve...

Abstract

A method for improving the marble pattern class of beef features that the feed of beef cattle, whose contents of VA and carrotene are lower than the standard (2200 IU / kg) is applied to the beef cattle for more than 90 days to increase the content of intramuscular fat by 90.6-280.3%, so improving the marble pattern by one class.

Description

a technical field [0001] The invention relates to increasing the intramuscular fat content of beef cattle by changing the content of vitamin A and carotene in the feed to improve the marbling grade of the beef, and belongs to the technical field of nutritional regulation and control of beef quality. Two background technology [0002] Beef is high in protein and low in fat, which meets the requirements of people's pursuit of nutrition and health care, and has a high consumption in western developed countries. With the improvement of people's living standards in my country, the consumption of beef, especially high-grade beef, has been showing a rapid growth trend. However, due to the long production cycle, high production costs and high technical requirements, high-grade beef has been heavily dependent on imports. [0003] Foreign countries have long reported that vitamin A is related to animal fat metabolism. One of the members of vitamin A family, retinoic acid receptors be...
