Diet and nutritional rules of an inseminating bull
The inseminating bull plays the most important role in the planned development of a cattle breeding farm. Feeding an inseminating bull has a number of features.
Bull inseminator
A balanced diet increases libido, improves sperm quality. The amount of feed depends on the weight of the male, breeding load. In winter and early spring, you need to increase the amount of vitamins and minerals.
Features of the diet of inseminators
When it comes to cattle producers, their breeding value plays a major role.
It characterizes the genetic potential of the bull, its ability to give offspring suitable in terms of economic quality. From such individuals, cows are born that have high milk production. The offspring has hereditary good physical performance and health. The normal development of qualities is influenced by feeding.
Care for breeding males needs appropriate. A balanced diet is designed to increase libido, activity, quantity and quality of ejaculate. Also, sensible feeding will help keep the bulls healthy and use them for offspring longer.
An excess amount of feed also has a bad effect on producers, as well as an insufficient one: bulls begin to fatten, the photo shows that it is the inseminators that are distinguished by their large growth. Obesity reduces sexual desire, males do not mate. Their behavior can become aggressive. The quality of the sperm gets worse.
When compiling the diet of the inseminator, the following parameters are taken into account:
- age;
- breeding load;
- number of days of rest;
- body weight.
The manufacturer must be getting enough protein. This is the most important component of the diet. It forms muscle mass, influences the composition of the semen. A healthy adult male cattle must be large, tall, with a broad chest and minimal fat mass. Vitamins and minerals also significantly affect the health of males. Vitamin A plays the greatest role: it is involved in the regulation of the activity of the gonads in cattle.
How to feed young bulls
Sire bulls can be obtained from the mating of a cow and a male with a high breeding value. The correct diet will help to grow a strong, handsome, healthy and active male.
A calf up to one year of age should actively gain weight (up to 1 kg per day), therefore, the animals are fed abundantly. By the age of 12 months, the body weight of the bull will be up to 330-360 kg. Proper nutrition of young males will ensure good performance in the future.
After reaching the age of one year, the gobies begin to feed in moderation. A correct diet ensures the normal development of the gonads, accelerates the onset of maturity. Ejaculate can be collected from a healthy young bull, and the quality of the future breeding offspring can be assessed. The breeding value must be high. The sperm of such an animal is used for insemination of cows.
Harmonious nutrition for bulls over one year old weighing 330-360 kg:
- Green food.The basis of the diet is hay from grass, cereals and legumes. The food must have good taste.
- Compound feed, simple in composition. The components of the compound feed are grain (corn or oat), a product with a high protein content (meal, dry return).
If necessary, vitamins A, D and mineral supplements (table salt, phosphates) are added to the feed. You need to water the gobies with clean water. Proper care will allow you to raise a productive inseminating bull.
Males begin to inseminate cows from 1.5 years, the breeding load is constantly growing and becomes maximum when the bull reaches three years of age.
How to feed adult breeding bulls
The breeding bull's diet needs to be adjusted every month. It is important to consider such factors:
- live weight;
- fatness;
- the appearance of the hairline;
- condition of the front and hind legs;
- the quality of the glaze on the hooves;
- behavior towards other animals and humans;
- evenness when standing, ease and speed of walking;
- interest in food.
If the inseminator has noticeably gained weight, his gait is heavy, his legs buckle. These are clear signs of the onset of obesity. The intensity of the feeding should be reduced. Loss of appetite may indicate vitamin deficiency or problems with the gastrointestinal tract.
The breeding bull should receive an equally rich diet all year round so that the breeding load on him does not decrease. In winter and early spring, hay loses its nutritional value and vitamins, so nutritional supplements are purchased for this time of year. Avitaminosis in a bull will lead to impaired sexual function and a decrease in sperm quality.
The inseminator needs 2 or 3 meals a day. Feeding is carried out from a separate feeder. In the morning, a large bull producer is obliged to eat half of the daily amount of compound feed, 1.5-3 kg of hay. When the semen is taken, the bull is fed exclusively with compound feed in the morning. Hay is given after sampling biomaterial
How to feed breeding bulls
The vitamin and mineral composition of the feed must remain constant throughout the year. You need to feed the bulls using the following components:
- Green hay. Use hay from legumes and grasses. If a bull weighs 600 kg, he is given 10 kg of grass per day, 800 kg - 11 kg of grass, 1 ton - 13 kg of grass.
- Combined feed. Consists of a mixture of: oats (35%), wheat bran (24%), wheat grains (5%), barley (16%), sunflower meal (10%), yeast (3%), impurity of skimmed milk powder (5%) ), table salt (1%). A bull weighing 600 kg is given 2.8 kg of compound feed, for 800 kg - 2.9 kg, the largest bull weighing 1000 kg should receive 3 kg of compound feed.
- Animal product. Mix with frequent use of the bull (insemination 2-3 times a week). Meat and bone meal, fish meal, chicken eggs, etc. are used.
The inseminator needs 2 or 3 meals a day. Feeding is carried out from a separate feeder. In the morning, a large inseminating bull should eat half of the daily amount of compound feed, 1.5-3 kg of hay. When the semen is taken, the bull is fed exclusively with compound feed in the morning. Hay is given after sampling biomaterial
Diet of bulls in winter and early spring
In summer and autumn, there are enough vitamins in green hay. In winter, bulls may not have enough vitamins, so the diet of inseminators is adjusted. Additives with vitamins A, E and D are mixed into the feed.
The norms of vitamins for livestock must be indicated on the packages. From minerals used sodium chloride (kitchen salt), feed phosphate. You also need to increase the amount of protein in the diet, this is also important for the cow. It is advisable to add 50-400 g of skimmed milk powder to the feed daily, 4-5 pcs. chicken eggs, blood or bone meal, 2-3 liters of skim milk. A rich diet during the winter season can maintain a high level of sperm production.
What food to choose
The quality of the feed must always remain at a high level. It should include a variety of components, each of which performs its own function.Recommendations will help to make feed better:
- Cereal grasses are mowed during the period of spikelet formation. Legumes are harvested after flowering begins.
- From cereal plants it is better to choose bluegrass grasses, fescue, fox tail.
- Good quality hay should be stored in a dry, ventilated area, protected from rodents.
- A good compound feed must have a varied and rich composition.
- New batches of compound feed must be sent for inspection to the veterinary laboratory. There they will check its safety for the animal.
After harvesting, hay is given for feeding the bulls only after 30 days. Instead of compound feed, if the assessment has shown its unsuitability, you can feed the animals with a grain mixture of oats, barley and wheat. A stock of such a mixture should always be on the farm.
Breeding bulls must eat well, then they will have quality seed. The diet has a direct impact on sexual activity and future offspring. The amount of feed depends on the load on the bull, its current weight. It is necessary to adjust the nutrition of the animal on a monthly basis, but do it in accordance with the rules, without violations, without overfeeding, etc.
