About biological characteristics A domestic cow is a female cow, which is a subspecies of the wild bull. If we talk about the classification of cattle by age, then a bull is an adult male, and young animals (a child of a cow) are a bull, a calf or a heifer.
WHAT IS A MINI JERSEY COW? Mini Jersey cattle are exactly what their name suggests: a smaller version of a standard-sized cow. The miniature classification refers solely to their size. Mini Jersey cattle do not have tiny heads and legs attached to a large body. If you see a jersey that fits this description, it is technically a midget and not a mini. Dwarfism in Jersey cattle is a genetic defect of the D2 gene.
Intensive hunting led to the gradual disappearance of the wild bull. In the Middle Ages, it was already a rarity in European forests, and its last specimen is believed to have died of disease in 1627 near the Polish village of Yakturov. It is not clear exactly where the aurochs was first domesticated. Places such as South Asia, the Mediterranean, and the Iberian Peninsula are mentioned. Some researchers suggest that the aurochs was domesticated in different parts of its extensive range.
Methods and assessment of accounting for the milk production of animals Breeding highly productive cows is one of the most profitable areas of animal husbandry. Dairy products are in high demand all over the world - to meet all needs, more milk must be produced. Progressive farms devote a lot of effort and attention to the scientific approach to animal care. Evaluation of cows by their own productivity is a quantitative and qualitative characteristic of milk yields for a certain period of time. Not only the volume is checked, but also the density, as well as the percentage of fat in it.
Dairy nutrition of cattle One of its elements is adequate nutrition – a key factor in the cultivation of dairy cattle. It also has a huge impact on production results. Unfortunately, when the price in purchases falls and the profitability of milk production decreases, breeders, in search of savings, most often refuse to buy ready-made feeds, in particular, limiting mineral and vitamin supplements in food doses. This is very unfavorable, and in the long run it could mean even more losses. The milk production of a cow will not decrease overnight, but stopping the use or reducing the doses of mineral-vitamin mixtures recommended by manufacturers for several weeks will negatively affect the health of the animals. This apparent savings can lead to even greater costs over time. Vitamins are organic compounds that, in very small amounts, are essential for the proper functioning of the animal body. They serve to maintain its vital functions - growth, development, health, fertility and productivity.
In the spring, we harrow the field and wait for the weeds to germinate, which we destroy with the help of crop processing: harrowing, cultivating, cultivator, disc drive, etc. - depending on the farm equipment. We plant seedlings in already clean soil in May, June and even until mid-July. Last year (2008), as a result of the June drought, I planted swede on July 12-15 and, due to the favorable weather, got a better harvest than in some previous years. And this year (2009) - the weather was very favorable for swede and the yield was record. I think rutabaga in deep grooves made by a potato chipper. These grooves are quite important because they allow water to flow from the rainfall to the roots of the seedlings. The width of the rows, like potatoes. Seedling distance every 40 cm. It is not worth it thicker, as small roots are obtained. For planting, a seedling seeder is useful, for example, for cabbage (then we do not make grooves), but I think by hand. The swede is very well taken, and it is enough to lay it in a groove and cover it with a small amount of earth.
Breeding ostriches - what's the use? Ostrich Meat Ostrich meat is primarily harvested for its outstanding taste and nutritional qualities. It is characterized by low content of fat and cholesterol. They pay for one adult ostrich. Ostrich Eggs Another product that you can get from an ostrich is eggs. An ostrich egg weighs about 1.5 kg, which is equivalent to about 20 pieces of chicken eggs. One egg bought directly from a breeder costs about PLN 50, while in retail chains prices for ostrich eggs can be twice as high. Ostrich eggs are not only an interesting sight on the table, but also a great value for health. They have a delicate taste and much less cholesterol than chicken eggs. Ostrich leather Ostrich leather is also extracted, which is of great importance in the haberdashery market. Belts, handbags, gloves are made from it. About 1.2 m2 can be rented per person. The leather on the chest and back is of high quality and is most preferred by manufacturers.
Rest areas in cowsheds When creating conditions for cattle to rest in a lying position, it should be remembered that a cow will repeatedly get up and lie down in a den (about 10-15 times a day). Changing the position from standing to lying leads to the fact that the cow rests with her entire mass on a small area of \u200b\u200bthe wrist. Too hard or too soft material used in dens can damage the animal's joints. Therefore, a material that warms up under the pressure of the cow's wrist from 16 to 28 mm is suitable. Too soft is not good, as it makes it difficult for animals to get up and down, while a floor that is too hard can put undue stress on cows and increase the risk of compression injuries. The surface of the material covering the floor must not be rough, as this may lead to abrasion of wool and other injuries. It is recommended to use a substrate with a coefficient of friction of at least 0.5 m, which corresponds to a dry concrete slab. It must be clean, dry, anti-slip, deformable and insulating. The choice of material for a pet bed depends on how the animals are kept and the type of floor. In prisons and freestanding sheds, m.in. are used for mulching: mats and mattresses, straw and beads.
