In order for animals not to lose sexual activity, feeding the producers' bulls is organized according to a special scheme. Special diets are added to the normal diet, which allows you to maintain a good state of muscle mass. These supplements increase the reproductive functions of livestock, but their number must be correctly calculated. Our article will tell about how the menu is compiled for breeding males of cattle, on which healthy and strong offspring depend.
The future sire was born
For breeding animals selected the strongest and most complete calves immediately after birth. They must have a good pedigree and be completely healthy. As for the assessment of future productivity, it can only be determined presumably. Based on the indicators of parents, brothers, sisters, or more distant ancestors. And then they think about how to properly feed the newborn.
From the very first days of life, such a calf begins to be prepared for its future profession as a producer. Why use special feeding methods. This mode, and the quality of feed, and various food supplements.
The average weight of a newborn bull is 45-50 kg. In the first days of the birth of a baby fed colostrum 2-3 times a day. The total volume on the first day is 1 l, on the second - 2 l, on the third - 3 l. To control the rate, it is fed from a bottle.
Grows by leaps and bounds
The transition to milk occurs around the fourth day. The daily rate is one fifth of the weight of the calf. In the first 7 days after calving, it is divided into 5 receptions. In the second week - at four. From the third week go on a constant three meals a day.
From the second month of life of the future producer begin to accustom to the usual food of cattle. For a calf weighing 75-80 kg, 10-12 kg of hay, 32-35 kg of feed, 300 g of salt, 450 g of feed phosphate will be required. These norms are the same for the summer and winter stall period. However, in the cold season in the diet add another 30-35 kg of silage. Green food and root vegetables do not give a baby at this age.
In the third month, the amount of hay doubles, and the daily rate of feed reaches 45 kg. Mineral dressings remain at the same level. When kept in a stall in winter, the calf is already given up to 10 kg of root crops, and in summer - 65-70 kg of green fodder.
As the young bull grows, there is a constant change in the amount of feed it uses. And by the sixth month, when the animal weighs 200 kg already, its daily ration is:
- green fodder or silage - 140 kg (in summer);
- hay - 90 kg (in winter;
- feed - 50-55 kg;
- root crops - 30-40 kg (in winter);
- 750 g of feed phosphate and 600 g of salt (regardless of the season).
These products are mandatory when feeding bulls. And mineral supplements, although they are the last line, are very important. They increase the amount of calcium and phosphorus in a young growing body, laying reserves for the future. Their lack of a negative impact on productivity and reproductive activity in general.
With this diet, by the age of 16 months, a bull-maker weighing 500 kg will be obtained. Some believe that the one-year-old gobies can already be allowed to breed. But we recommend starting half a year later. After reaching one and a half years, the young male is considered ready to mate, and to calculate the diet, not only its weight, but also the sexual load is now taken into account.
How it works, and eats
Changes in the quantitative indicators of the diet, taking into account the weight of the bull producer and sexual load are shown in the table:
When feeding the producers' bulls, it is allowed to use only first-class products, that is, the best quality. This is especially true of hay, haylage and silage. Diligent farmers who care about animal health, before feeding the bulls with newly purchased food, hand it over to the laboratory for analysis.
Those owners where there are no such check points, we advise you to use a special reference book of livestock in the preparation of the ration. There you can at least roughly calculate the nutritional value of each plant that goes into food.
With a high sexual load, the males make their rations even richer, feeding the animals with concentrates and other protein-rich foods. In the summer, good condition is maintained with fresh carrots, and in winter special additives with carotene and vitamins A, B and E. The daily menu of an adult bull should include 400 g of meat and bone (or fish) flour.
Adults eat less children
Let's take a closer look at what to feed the bull, responsible for the tribe, in winter. To begin, we determine the percentage of different feeds in the diet. Let's start with rough food. In cold weather, hay should be between 20 and 40% of the total volume consumed. Silo, vegetables and root crops - 25-30%. Concentrates - up to 50%.
For example, if a three-year-old bull weighs 1000 kg and the load on its sexual functions is high, then it will need per day:
- hay (from alfalfa) - 3.5-5 kg;
- hay (from cereals) - 5-6 kg;
- corn silage - 7-8 kg;
- carrots - 4 kg;
- beets (sugar) - 4-4.5 kg.
The fact that the diet of an adult bull is less than the amount of food consumed by a calf selected for the tribe should not be surprising. Up to about 1-1.5 years, the animal grows, and all the nutrients are spent on that. If you start a mature male to feed with the same intensity, then he will simply become obese. So it is necessary to observe moderation in order to keep cattle active.
Now consider how to feed the breeding bulls in the summer. The most useful food during this period is fresh grass and vegetables. These products are added to the diet of animals. To maintain the balance of the day a male will be quite enough 20-30 kg of green and 10 kg of vegetables. Too much greenery reduces sexual activity.
Fresh plant foods are well absorbed by the body and provide energy. Especially useful sugar beet. Year-round diet of the breeding bull should be enriched with vitamins and minerals. Do not forget about fish oil (50-100 g per day), chalk (50 g), tricalcium phosphate (1% of the total mass of feed) and salt (100 g). All this is given twice a week and no more often, mixing with compound feed.
There are strict restrictions. In no case should not give the bull-producer to use cruciferous plants - rapeseed, colza, cotton. This adversely affects the quality of sperm and inhibits reproductive functions. Taboo is imposed on such products as bard, pulp, pulp and oilcake and all the same cruciferous, as they can disrupt iodine metabolism and adversely affect the thyroid gland.
In the fight for quality
The quality of seminal fluid is also affected by interruptions in the diet. To prevent this from happening, you need to feed the bulls only by the hour, and feed them in the following order. In the morning, give concentrates, silage and root vegetables. Lunch consists of fresh grass (or hay) and root vegetables. For dinner, concentrates and herbs are served again. Be sure to follow the standards of feed, which were listed above. If the breeding bull grows fat, then its spermatozoa become less active. Excessive hunger strikes lead to the same result.
The question of whether it is possible to feed a breeding bull with bran does not even have to arise. To replenish the body with protein, people usually use flax cake, bean silage or grass.
However, wheat bran does not yield to them. They are used in a dry form or are already included in the composition of the feed.
In the first case, for a bull weighing 1000 kg per day, 1 kg of bran is sufficient. At the same time he will receive 130 g of digestible protein. In the second case, the portion will be about the same, but will enter the body along with other components.
Use our advice: when preparing the male for the period, enter into his diet chicken eggs (6-7 pieces daily), germinated grain 1-2 kg), fish (or blood meal) flour (1-2 kg). This will increase the sexual activity of the bull and improve the quality of sperm.
