Inseminator bull: feeding and maintenance, use and giant individuals

To increase the productivity of livestock in farms, breeding work is carried out. For this purpose, inseminators are used. For the role of producers, the best representatives of the breed are chosen, who have good he alth, high libido, and also have an impressive size. It is important to provide quality care and adequate feeding of animals.

Origin of producers

The first attempts at selective selection have a long history of development. Quite quickly, people realized that the productivity of the offspring depends not only on the maternal direction. The bull's data also affects the quality. Such animals are valued in every household.

For a long time, cattle rearing took place naturally. A sire could cover several hundred cows during the year. This method incapacitated even the most hardy animals. The turning point was the period in the middle of the 20th century.

Soviet scientists have developed a revolutionary technology for those times for the artificial introduction of semen to cows. The method made it possible to maintain the he alth of breeding animals and increase the number of fertilized individuals.

Largest examples of breeding bulls

Stud bulls are powerful animals obtained as a result of centuries of selection. A weight of 1 ton is an average for breeding cattle, and this is not the limit for animals. Some specimens with their size and weight stand out even against the background of their huge counterparts.

Porcelain bulls

The largest are porcelain bulls. The impressive dimensions of the animals were influenced by the genes of Podolsk cows. As a result, real giants were obtained. The record holder is considered a bull from Switzerland named Donneto. With a height of 1.9 meters, the weight of the animal is 1.7 tons.

Trigger

Another member of the unofficial ranking of giants - bull Trigger comes from the UK. The representative of the Freesian breed weighs 1.2 tons, and the animal reaches a height of almost 2 meters. And although the animal is not aggressive and has a calm disposition, its horns were cut off. This measure is designed to ensure the safety of tourists who like to be photographed against the backdrop of a strong man.

Field Marshal of the Cherolais breed

Bull Field Marshal is called the pride of England. A magnificent example of the Sherola breed every year adds 150 kilograms in weight and has already exceeded the mark of 1.5 tons. The intimidating appearance does not frighten the owner, who considers the giant a calm and peaceful animal and even left him horns.

Repp

Bull Repp from Ukraine is known not only for its impressive weight (1.5 tons). During the year, as a result of using the producer's seed, about 50 thousand he althy calves are obtained. This giant is extremely aggressive and vindictive. And even sawn horns do not guarantee safety when communicating with an animal.

Gaura

Gaurs are wild bulls that live in the southeastern part of Asia. With a weight of 1.6 tons in height, they often reach almost 3 meters. Unbridled temper and remarkable strength scare away other predators from animals. Only crocodiles and tigers can resist the giants.But fighting skills do not protect animals from poachers. Recently, the population of gaur bulls has decreased to 20 thousand individuals. The animal breed is listed in the Red Book.

Selection principles

To improve the breed, breeders take as a basis the properties of male line sires. Main factors for choosing inseminating bulls:

1. Pedigree of a breeding animal.
2. Features of development from birth to 12 months of age. Assess the rate of muscle growth of the animal and the exterior of the young.
3. Checking the quality of sperm. Several dozen representatives of the opposite sex are fertilized with the seed of one-year-old bulls at once. Less than half of pregnancies are considered unsatisfactory.

Success of breeding work also depends on the conditions of breeding bulls.

Containment conditions

To obtain the qualitative characteristics of the offspring, the rules for keeping animals are observed:

1. Inseminating bulls are provided with an active lifestyle. Walks don't have to be short. Animals need at least 3 hours for walking and additional activities.
2. Take into account the temperament of bulls. If the farm does not practice complete isolation of producers, then they limit the contact of calm animals with unbalanced ones.
3. Keep the rules of hygiene. All body parts of bulls, including hooves and genitals, are washed daily.
4. Also regularly keep the paddock clean.
5. Inseminating bulls are kept only in spacious, ventilated and bright rooms. Lack of comfort negatively affects the psyche of giants and reduces the quality of sperm.
6. The animals are kept on a chain, the rope leash is not strong enough.

The mode of each breeding bull consists of several items:

1. 3 meals a day.
2. Rest after each feeding session.
3. Walk and work in the middle of the day.
4. With natural fertilization - evening mating.

Violation of the usual daily routine or poor living conditions affect the reproductive ability of the animal.

Diet

The productivity of inseminating bulls depends on the quality of the food. Lack or excess of nutrients adversely affects the condition of the animal's sperm.

The consequences of feeding failures are sometimes eliminated within 2 months.

The menu includes various products that ensure the normal development of animals:

Food	Share in daily diet, %
Barley or oats	25
Sunflower or soybean meal	20
Corn (must be chopped)	16
Bran	15
Molasses or sugar	10
Yeast	5
Recycled fish waste	5
S alt and phosphates	2
Vitamin supplements	1

S alt is very important for breeding bulls. This product replenishes the deficiency of minerals in the body of animals. It is given in the form of a lick or added to the composition of combined feeds.

Bulls are also provided with enough vitamins. Lack leads to serious consequences:

Growth retardation and atrophy of animal genitalsE, mg365 D, ME

Types of vitamins	Needed amount	The result of underconsumption
A,mg	650
	Failures in the metabolic processes of the body, pathology of the limbs of the animal
14000	Degeneration of the muscle tissues of the skeleton and heart of the animal

The inseminating bulls are fed 3 times a day. The main meal, about 70% of the daily diet, falls at lunchtime. Leftovers are evenly distributed between morning and evening feedings.

Insemination

In farms, 3 methods of animal insemination are used - natural, machine and artificial insemination.

Natural on the range

The bull-inseminator is released for grazing along with the rest of the livestock. The animal covers cows that have reached the peak of sexual arousal.

Pros and consHigh percentage of successful cases of fertilization.The method does not require the use of additional tools and devices.Low efficiency. The animal does not always have enough strength to fertilize the entire herd.In the event of a disease, even one individual leads to a rapid infection of the livestock.

Natural range is suitable for small private households.

Machine

For mating, a special machine is purchased, on which the bull puts its front legs. Then cows that have reached puberty are brought to the animal.

Pros and consUniform distribution of the load on producers.Possibility of registration of all cases of insemination of animals.Prevention of the spread of infections among animals.Violation of sexual cyclicity in inseminating bulls during isolation from the herd.

Artificial insemination

In artificial insemination, the semen of bulls from producers is collected in advance. For storage, hermetically sealed containers are used, which are placed in liquid nitrogen.

Pros and consOne portion of sperm is enough to fertilize a dozen females.To update the livestock, you do not need to purchase new animals.Possibility of long storage and transportation of seed material.The risk of infection of animals is excluded.Expenses for the purchase of additional equipment and the organization of a separate room for each animal.The need to attract experienced professionals.

The use of artificial insemination of animals has a positive effect on economic performance. The success of breeding work depends on the integrated use of all recommendations. Comfortable conditions for keeping animals, a balanced diet keep animals he althy, lead to an increase in livestock and the preservation of the breed.
