How to buy cows
The selection criteria require a sturdy body, well-proportioned structure, shiny coat, thin and elastic skin, thin and firm bones, moderate body length and width, flat back, wide buttocks, good chest development, large abdomen without sagging, body Observed from the top, side, and back of the three positions was "inverted triangle", black and white flowers were obvious. The limbs are firm, straight, and the breasts are large. They are square and round. They extend forward and backward. The front line is perpendicular to the front edge of the waist angle. The bottom is horizontal. The bottom line is slightly higher than the hock. Mammary gland development is adequate, and the nipple is of a moderate size. Symmetrically, the milk veins are thick and curved, and the milk wells are large and deep. The elasticity of the breasts was good with the hands, the milk wells before the milking were obvious, the breasts swelled, the breasts became smaller after milking, and the folds appeared in the back of the breast. This is a high-yielding dairy cow.
Age selection Cows are of different ages and there is a big difference in milk production. When the first child is born, it is usually about 2.5 years old. With the increase in parity and age, the milk production also gradually increases. When the child reaches the age of 4-7 (ie, 6-9 years old), the output reaches the highest peak. decline. Therefore, farmers who are going to raise dairy cows should purchase young and middle-aged cows aged 3 to 5 years old.
In addition, we must also understand the pedigree of the dairy cows you have purchased. The so-called pedigree is the ancestry of cattle. We look at the production performance of the dairy cow's parents, grandparents, and great ancestors.
Finally, before the transaction, you should check with the veterinary health and epidemic prevention department whether the dairy cow you are looking for has infectious diseases such as tuberculosis, whether the genital organs are normal, and whether there are heterosexual twins (heterosexual twins have no reproductive ability). And cows should be purchased from large, regular dairy farms.
An advanced Non-Invasive Diagnostic Device for physical examination & analysis system, using the light wave resonance to scan and detect the functional status of the Human body or to trace the gradually formed abnormal conditions in the tissue, cell, chromosome, DNA helix, molecule or entire organ, then provides treatment.
Metatron Hunter 4025 Purpose:
The Metapathia-GR Hunter software can operate only with the telemetric nonlinear analysis data processing apparatus "Metatron" and its subsequent modifications. The telemetric nonlinear analysis data processing device is compatible with the IBM-type PCs and intended for studying reaction of a biological object to different types of the informational impact. "Metatron" allows correlating the measurement process with the process
affecting it and performs the following operations:
1) It measures J (0) which mirrors the change of the describing parameter, and the entropic potential relative to its initial value;
2) It transforms continuous signal J (0) with the preset intervals of frequencies into a histogram (a row of numerical values of scanned frequencies with serial numbers from 1.8 to 8.2 Hz.);
3) It sends the current W values to PC and displays the graph on the monitor simultaneously with its impact on the examinee.
4) It accumulates the W value in its memory unit, if observing the histogram is more convenient upon completion of the measurements;
5) It issues the scale-correlated commands required for regulating the effect on the examinee at testing;
6) It transmits the W values from the unit into PC memory upon completion of the measurements and saves them in unit memory of prior to the
beginning of recording data of the next measurements.
