Blood Card For Cattle
In Blood Card, your life value is equal to the number of cards in your draw pile. When you get hurt for one damage, you have to discard one card. If you have no cards left, the game is over.

DNA Sampling and Application in the Cow HerdThis is a guest post written by Sean McGrath, a rancher and from Vermilion, AB.DNA is the genetic code that determines how an animal grows, performs and interacts with its environment. Every animal inherits DNA from its parents with ½ coming from the maternal side and ½ from the sire. The building blocks of DNA are four base pairs: Adenine (A), Thymine (T), Guanine (G) and Cystosine (C).
DNA is arranged in long ‘double strings’ in which A and T are paired and C and G are paired. A ‘gene’ is an area of this double string that codes for a specific function in the animal. Dream of mirror online bot.
By substituting one or more base pairs in the gene (i.e.: replacing an AT pair with a GC pair) a different function may be expressed in the animal (i.e.: red coat colour vs. Black).Technology to examine DNA in cattle has been around for several years, however in the past it has been cost prohibitive. Newer technology called SNP (pronounced “snip”) has changed much of this and made DNA testing a viable option for beef producers, even at commercial industry levels.
SNP technology looks for changes in base pairs along the string of DNA. It does not look for specific genes, but rather examines areas that may be ‘associated’ with or close to regions of DNA that code for specific proteins or functions. The advantage of SNP technology over previous tools is that it allows us to examine many more pieces of DNA at a low cost.SNP technology may be used in several different ways including parentage determination, traceability, trait assessment, genetic defect testing, enhancing accuracy of genetic evaluations and sorting cattle into management groups.

(Links to the main Canadian labs: and )Because various breeds are the result of differences in their DNA, some tests may be breed specific or be more effective in one population than another. It is important to check if any available test is specific to the breed or crossbreed in question.Most producers will not want to jump right into parentage or testing for various traits, however collection and storage of DNA on your herd can be a valuable management tool at a relatively low cost. Having DNA samples readily available allows you to easily access the technology at the time and level you feel is appropriate. Some feedlots are now requesting cattle that fit specific genotypes, so it might be worth having your cattle’s DNA samples on hand so that you can be an eligible supplier. Another example: if you have calving problems, it will be possible to rapidly assess whether the problem is with a specific sire or a more general management problem involving cattle from several sires.
Collection and storage of DNA samples is an inexpensive way to prepare for these types of scenarios.It is useful when collecting samples to collect them early in an animal’s life and at a convenient time such as during regular processing. Collecting new sires as they are delivered to the farm, or replacement heifers as they are selected for the cowherd is a good practice. If an animal dies or is disposed of such as a cull bull that you may want to test, you cannot retroactively collect samples.
As well, in the event that you want to use testing for serious issues such as calving difficulties or genetic defects you do not want to have to run the entire sire battery or cowherd through the chute in the middle of a busy period.Since every tissue in the animal contains DNA, options for DNA samples include tissue, blood and hair. Hair is the easiest and cheapest to collect and store, as the DNA in the root bulb of the hair decays very slowly. Tissue samples, which contain a higher quantity of DNA than hair samples, must be collected and stored using specialized containers with preservatives or be frozen in order to prevent the DNA from breaking down, but they work well if you are testing right away. For long term storage, hair can be placed in a paper envelope labeled with the animal’s tag and stored in a dry and dark location such as a filing cabinet. How to collect tail hairs for DNA sampling.
Thanks for your question Blair. The answer is not simple unfortunately.One of the biggest variables is what were the genetics of the training population that the specific test was developed from and is there a correlation to the genetic makeup of the animal being tested.
Many of the original tests were developed off Angus based animals so had poor DNA or Genomic ties to other breeds.
This study examines the hypothesis that susceptibility of cattle to high-altitude pulmonary hypertension and heart failure (high mountain disease) is genetically transmitted. Eight offspring of cattle recovered from high mountain disease were considered 'susceptible.'
Eleven offspring of healthy cattle residing at high altitude were considered 'resistant.' At the resident altitude of 1,524 m, 10-day-old susceptible calves had higher pulmonary arterial pressures than did resistant calves (34 vs.21 mmHg), but at 90 days of age the pressures for the two groups were similar (26 vs. After 64 days of exposure to an altitude of 3,048 m, the susceptible calves (87 +/- 7 (SE) vs. 40 +/- 3 mmHg). By 124 days at 3,048 m, all susceptible but none of the resistant calves had developed heart failure.
The results indicated that susceptibility to pulmonary hypertension at high altitude was inherited. Susceptible cattle may provide a useful model of human hypoxic pulmonary hypertension.
