To select high-yielding cows to "five look"

A look at dairy cow breeds in the world, mainly Holstein (also known as black and white cows), Juan Shan cattle and so on. More than 95% of China's dairy cattle breeds are Chinese Holstein cows (Chinese black-and-white cows), as well as Xinjiang brown cows, Sanhe cattle and grassland red cows. Holstein is a large dairy cow with high milk production. The highest annual milk production in China is 8773.2 kg, and the highest milk production in the United States is 30833 kg. The milk fat rate is 3.3%. Holstein cows should be preferred for feeding cows. Secondly, it is an important basis for selecting high-yielding dairy cows to measure milk production and milk fat percentage indicators. For each dairy cow produced, milk production should be measured once a month, and milk fat rate should be analyzed once by the milk collection unit. Under normal conditions, dairy cows produce calves 1 time in 1 year, 2 months before termination of milk production, and 305 days in one year (one) lactation period. From a genetic point of view, there is a negative correlation between milk production and milk fat percentage. Therefore, in selecting high-yielding dairy cows, milk fat percentage should be considered in addition to milk production. Secondly, high-yielding dairy cows have one more characteristic. The peak period of milk production after delivery is later than that of low-yielding cattle. The high-yielding cattle are 56-70 days after delivery. The low-yield cattle are 20-30 days after delivery and the peak duration is longer. Long (about 100 days); after the peak period, the milk yield of the high-yield cattle is lower than that of the low-yield cattle. Therefore, to purchase dairy cows, the purchaser must check the milk production records of the cows to be purchased or observe live milk production on the spot. Third, look at the appearance and appearance of dairy cows The relationship between the appearance of dairy cows and their milk production results is very close. Practice has proved that the selection of a good body shape, especially good breasts and limbs, is very important for improving milk production performance. The body characteristics of normal high-yielding dairy cows are large in size, large in medium volume, obvious in breast size, good in breast attachment, strong in limbs and feet, and moderate in nipple size. Specific requirements are: American Holstein adult bull weight 1100 ~ 1200 kg, body height 160 ~ 165 cm, into cows 600 ~ 700 kg and 140 ~ 145 cm; overall is a triangle, that is, from the front, with armor as the vertex, Shun The two shoulders lead downwards by two straight lines. The two straight lines are wider and downward. They are triangular; when viewed from the side, the hindquarters are deep, the forequarters are shallow, and the top and the ventral lines extend forward and intersect to form a triangle. The base of the breast should be extended and extended, with good adhesion; 4 milk areas are well-proportioned, and the rear area is high and wide. The nipples are vertically cylindrical and well-spaced. In short, those who have a high body size, a clear profile of milk, and a developed digestive, reproductive, and lactating organ must be able to eat, drink, and prolific milk. Fourth, the pedigree data view includes: dairy cow breed, cow number, date of birth, birth weight, adult body size, body weight, appearance rating scale, and cow's milk production scores. In the pedigree, there should also be parental and grandparental weights, appearance scores, grades, milk yields, milk fat percentages, and grades. Also check the records of the prevention and quarantine, breeding and health of cattle diseases. To purchase dairy cows, quarantine measures must be strengthened to avoid afferent diseases, especially tuberculosis, infectious abortion, leptospirosis, trichomoniasis, and mastitis. The age and parity of dairy cows have a great influence on milk production. Under normal circumstances, the initial age of 16 to 18 months of age, weight should reach 70% of the cow's weight. Generally, the first and second-born cows have lower milk yields, 3 to 5 fetal cows have increased milk production, and 6 to 7 fetuses have milk-producing amounts that have declined gradually. According to experiments, the milk fat percentage decreased slightly with the increase in the age and parity of dairy cows. Most people think that a high-yielding herd, if the average parity is 4 children, the reasonable parity structure is: 1 to 3 fetuses account for 49%, 4 to 6 fetuses account for 33%, 7 or more cows account for 18% .

Peptides are the building blocks of proteins which are formed by amino acids connected by a specific bond, but they are often easier to absorb than proteins. Peptides have a lot of benefits for us, such as the fatloss supplement in the cutting cycle, build lean muscle, assist with injury recovery, increase agility, and many other anti ageing benefits. SoBodybuilding Peptidesare very popular among bodybuilders and athletes. They are fond of running peptides products such as IGF-1, GHRP, GHRH as the fatloss supplement or stacking with Raw Steroids , human Growth Hormone, Sarms Raws in their cutting cycleto lose fat and gain lean muscle. 

In order to gain muscle mass and increase in strength or lose weight in a short time, some men prefer to use raw steroids or Human Growth Hormone or bodybuilding peptides to help them. However, if men take steroids in large quantities for a long time, it reduces a man`s ability to make his own testosterone. That because the excess testosterone in the body causes the body to down-regulate (decrease) its own testosterone production. This is the main reason why sexual dysfunction occurs in men who addicted in using steroids.

 

If someone have sexual dysfunction after running huge number of steroids or hormones, please take it easy, you could use some improved sexual dysfunction peptides to balance and improve the body's production of testosterone. Such as the PT141 and HMG. PT141 as one kind of bodybuilding peptides, it treats reperfusion injuries and shock from hemorrhages as well as in sexual dysfunction and low libido.

 

How to use PT-141?

PT-141 dose for men is:
500mcg - light
1000mcg - medium
2000mcg - strong
for women:
250mcg - light
500mcg- medium
1000mcg - strong

 

How to use HMG?

HMG (Frag 176-191) is a [piece" of the Human Growth Hormone peptide. This truncated version of HGH as fatloss supplement that actually surpasses the fatloss advantages of regular Human Growth Hormone! HMG release fats from fat cells into blood stream to be burned for energy. This powerful Frag peptide allows users to access fatloss power which is more than twelve times stronger than what they`d get via regular 191 amino acid human growth hormone.Anyone who wants to lose even the most stubborn fat deposits will benefit from therapy with this high-tech peptide. However, it`s generally marketed to those who lift weights. After all, a lot of bodybuilders tend to rely on Human Growth Hormone in order to spark easier weight loss during their cutting cycle, even keeping their bodies in a more youthful state.

Once you`ve reconstituted the formula, best times to take it would be morning, before workout and before bed, if only to be taken once a day them most beneficial will be before your cardio/weights session. Most people use 250mcgs at a time, but this will vary based on your weight. It s best taken when your stomach is empty, however, it s ok to use if you`ve eaten only protein. Carbs and fat may inhibit the effectiveness of this peptide.

How to store PT141 and HMG?

Our PT141 and HMG are sterile sealed freeze-dried (lyophilized) powder form to ensure that they`re fresh and pure with nothing removed or added to it.PT141 is commonly injected, thus we need to reconstitute it in bacteriostatic water and 10 mg vial reconstituted with 1ml of bac water.

 

You should keep PT141 and HMG in a dark place which is cool – this will ensure longer product life and efficacy. When you`re ready to start taking this peptide, you will need to reconstitute the powder with bacteriostatic water or sterile water before proceeding with a dosing. After reconstitution vial must be kept in fridge at all times to avoid degradation.
