Description
Technical field
The invention belongs to technical field of animal, and in particular to a kind of cow essence feed supplement and its preparation method and application.
Background technique
Captive breeding cow is the basis for developing beef cattle industries, and the culture efficiency of cow is mainly reflected in annual production one
Calf needs the feeding cost of reduction cow with a definite target in view to improve the culture efficiency of cow, and feed cost accounts for entire feeding
This 80% or so is formed, therefore, it is the key that reduce cow feeding cost that science, which reduces cow feed cost,.
Ox is ruminant, the ability with digestibility and utilization roughage, and corn stover is that beef cattle cow is good thick
Feed resource, the corn stover after especially rubbing, trophic level are equivalent to sheep's hay.Therefore, cow is fed using corn stover
It is to reduce the effective measures of feed cost, and realize that agricultural crop straw crosses an effective measures of abdomen returning to the field.
But mature cow daily required for nutriment include: protein, energy, sodium chloride, calcium, phosphorus, vitamin,
Microelement etc. meets Rumen physiology needs in particular for enough crude fibres.Only according to corn stover be not able to satisfy it is above-mentioned
Nutriment needs, especially the needs of crude protein, microelement, sodium chloride, calcium, phosphorus, VA, VE.The raising week of mature cow
Phase is generally 12-13 months, and each breeding cycle is divided into Early placental phase, second trimester of pregnancy, latter half of gestation, nursing period four-stage,
Early placental phase, development of fetus is slower, and the nutritional need of cow only considers to maintain to need, and needs, but arrives without the concern for gestation
Second trimester of pregnancy and later period, embryo growth and development is rapid, need to consider the needs of embryo growth and development, and with pregnant month
Increase, the needs of embryo growth and development are also increasing, it is therefore desirable to which cow diets of different nutrition level will also correspondingly increase.Lactation
Phase cow, with the increase of calf age in days, the nutriment of daily requirement is also increase accordingly.This requires in feeding corn stover
While, certain concentrate supplement (referred to as: smart feed supplement) to be also provided according to the nutritional need of cow difference physiological stage.But
It is current smart feed supplement, mostly can be only applied to a certain period of cow, the time of infertility of cow can not be used for.
Summary of the invention
In view of this, can be applied the purpose of the present invention is to provide a kind of cow essence feed supplement and its preparation method and application
In the nutritional need in the time of infertility of mature cow, especially meet Early placental phase, second trimester of pregnancy, latter half of gestation and nursing period
Feeding demand, and it is at low cost.

Embodiment 1
By 60kg mountain flour (Yu Feng animal husbandry Co., Ltd, Harbin City, article No. 6-01-069), 40kg sodium chloride, 50kg phosphorus
Sour hydrogen calcium (Yu Feng animal husbandry Co., Ltd, Harbin City, article No. 6-01-080) and 50kg premix (Beijing Sheng Da animal husbandry science and technology
Co., Ltd, article No. 156) it is stirred 15 minutes in premix agitator tank, it is uniformly mixed；
By 3250kg corn, 600kg dregs of beans, 400kg DDGS, 550kg maize germ and above-mentioned mixture stirring
It is mixed, is stirred 20 minutes in tank.
To above-mentioned smart feed supplement progress nutrient composition content analysis: crude protein % (cp%): 14%, crude fibre % (CF%)≤
4.5%, calcium % (Ca%:0.56%, total phosphorus % (P%) >=0.28%；Digestible energy: 14.14MJ/ kilograms.
The feeding effect of nursing period cow is tested in the smart feed supplement being prepared using embodiment 1
1.1 test periods and place: test period is on May 30,15 days -2018 March in 2018, and place is Huanan County
The concentric calf Breeding base in unity village, the township Ming Yi.
The selection and processing of 1.2 test ox:
Simmental within selection calving 15 days improves cow 45, is randomly divided into tri- groups of A, B, C, every group 15.A group
Daily ration essence is slightly than 12:88, and B group daily ration essence is slightly than being 18:82, and C group daily ration essence is slightly than being 20:80.
The grouping of 1 test ox of table and daily ration structure
1.3 test results are as shown in table 2 and table 3:
2 cow postpartum of table breeding gestation statistics
3 calf Gain weight of table statistics
From table 2 it can be seen that slightly two groups of cows of B, C than 18:82 and 20:80 are pregnant within 3 months postpartum for daily ration essence
Rate reaches 93%, and the A group compared with daily ration essence slightly than 12:88 has more 4.From table 3 it can be seen that the daily gain of two groups of calves of B, C
Level is also above A group, and significant difference.But difference is not significant between two groups of B, C.Pass through above-mentioned test, it can be deduced that, it gives
Cow feeds the daily ration that corn stover is main roughage, and it is very heavy to the breeding of cow postpartum and calf development to supplement smart feed supplement
It wants, using the formula essence feed supplement, the best concentrate-roughage ratio of nursing period cow is 18:82, can obtain satisfactory feeding effect.
Embodiment 2
By 24kg mountain flour (Yu Feng animal husbandry Co., Ltd, Harbin City, article No. 6-01-069), 16kg sodium chloride, 20kg phosphorus
Sour hydrogen calcium (Yu Feng animal husbandry Co., Ltd, Harbin City, article No. 6-01-080) and 20kg premix (Beijing Sheng Da animal husbandry science and technology
Co., Ltd, article No. 156) it is stirred 15 minutes in premix agitator tank, it is uniformly mixed；
By 1300kg corn, 240kg dregs of beans, 160kg DDGS, 220kg maize germ and above-mentioned mixture stirring
It is mixed, is stirred 20 minutes in tank.
To above-mentioned smart feed supplement progress nutrient composition content analysis: crude protein % (cp%): 14%, crude fibre % (CF%)≤
4.5%, calcium % (Ca%:0.56%, total phosphorus % (P%) >=0.28%；Digestible energy: 14.14MJ/ kilograms.
The feeding effect of cow summer nursing period is tested in the smart feed supplement being prepared using embodiment 2
1.4 test periods and place: test period is on August 30th, 1 day 1 May in 2018, and place is Shangzhi county
The town Mao Ershan Fan Huilin cow farm.
The selection and processing of 1.5 test ox:
It selects the Simmental of calving 35 days to improve cow 20, is randomly divided into two groups of A, B, every group 10.A group daily ration essence
Slightly than 16:84, B group daily ration essence is slightly than being 18:82.
The grouping of 3 test ox of table and daily ration structure
1.6 test results are as shown in table 4 and table 5:
Table 60 days 4 cow postpartum breeding gestation statistics
5 calf Gain weight of table statistics
Can be seen that daily ration essence from 4 table 5 of table, slightly two groups of cows of A, B than 16:84 and 18:82 are pregnant within 60 days postpartum
Rate of being pregnent reaches 90%.As can be seen from Table 5, the daily gain water of two groups of calves of A, B is average more than 1 kilogram, and difference is not shown
It writes, but the thick B group calf daily gain than for 18:82 of essence is more smart thick than for the high of 16:84.Pass through above-mentioned test, it can be seen that
Summer is the daily ration of main roughage to cow feeding corn stover, supplements 16% smart feed supplement and can meet cow postpartum and match
Kind and the nutritional need of calf growth and development.
The present invention provides a kind of cow essence feed supplements and its preparation method and application, utilize the cow essence feed supplement and rubbing
Corn stover carries out mixed feeding to cow, cow pregnancy rate within 3 months postpartum can be made to reach 93%, calf daily gain
Up to 0.96 ± 0.35kg or more, survival rate 98%, it is seen then that application smart feed supplement of the present invention can guarantee different weight, difference
The cow in stage searches for food to enough nutriments.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
