Productive indicators of cattle depend on proper nutrition. The norms and types of feed required are determined by the scientific departments of agricultural holdings. Every farmer should know how to feed cattle, taking into account accepted standards. How, when compiling a diet, to adjust it to the characteristics of the livestock and goals, will be discussed in this review.
What are the feeds
When compiling a diet, several important parameters are usually taken into account. Among them, the type of feeding, breed, productivity, physical condition of animals. So, in the summer green feeds are of great importance, and in winter, roughage and concentrates take on their function.
- coarse - hay;
- juicy - root crops;
- green grasses.
Concentrated feeds are substances that contain a dry mixture of nutrients. Their task is to improve the nutritional value of the diet and provide high productive indicators. Any mixture (feed) is enriched with vitamin and mineral supplements. The elemental composition and how to give them to animals is indicated on the packaging. Did you know? Cows - owners of 1 stomach with 4 different digestive compartments. Concentrates are usually made in the form of granules. They are very nutritious, so their amount in the diet does not exceed 50 g. Combined feed and premixes are included in this category.
Compound feed is a mixture of cereals with a high content of nutrients. The peculiarity of the compound feed is that it can completely replace the entire diet, and then we are talking about a complete replacement of all other feeds. If it only supplements the main diet, then it is a concentrate. The third group includes various feed additives: yeast, protein and vitamin complexes.
The composition of the feed includes:
- cereals - wheat, oats, barley, corn;
- legumes - fodder beans;
- Pancake week crops - a sunflower.
- vitamins A, C, E, K, D, a group of vitamins B;
- trace elements - iron, copper, manganese, iodine, zinc, cobalt;
- meal and cake;
- a piece of chalk;
- table salt.
Premix is a mixture of biologically active elements (vitamins and minerals). This is a powdery mass, which is added to the wet mixes, enriching their composition.
Typical premix composition:
- a set of vitamins A, B, C, D, E;
- minerals: magnesium, iodine, selenium, calcium, zinc, copper, sulfur, iron;
The composition of roughage includes:
- young branches of trees.
Did you know? Cows spend 8 hours a day eating, 8 hours chewing gum and 8 hours sleeping.
Daily rate of hay
The rate of hay is calculated per 100 kg of live weight. On the day it needs about 30 kg with a ratio of 2-6 kg of hay per 100 kg of weight. Hay is involved in the regulation of milk formation. So, during the dry season, hay is 50% of the diet, and during lactation - only 25%.
Why do not eat hay
Hay has different nutritional values. Spring, mowed in the budding phase, contains the maximum amount of nutrients. By autumn, grass will lose most of its nutrients. Such hay is called “poor, ” and cows can refuse to use it (especially if there are more delicious ingredients in their diet).
It is useful to know how much hay a cow needs per day.
Juicy foods include:
- root crops, tubers and melons.
Did you know? The average cow consumes about 45 kg of feed per day. Silage is harvested from green mass by fermentation in special silage pits. Due to its nutritional properties, it improves digestion and helps the absorption of other feeds. Mowed grasses are also used for haylage. They are dried and after 2-3 days, when the degree of drying reaches 50%, they are rolled up.
Green feeds are grasses that grow in the grazing zone. It can be meadow herbs, garden weeds - almost any kind of plant.
Determining what feed cattle in one or another period of the year, take into account the absence of green feed in the winter. The winter diet should be more nutritious than the summer one, because the animal needs not only to gain weight, but also to maintain body temperature. Therefore, cereals and concentrates are required.
In winter, food should contain a sufficient amount of energy and protein, as well as mineral and vitamin supplements. In very cold weather, additional food is provided for feeding, which maintains the state of the body and allows you to gain weight. Animals are fed twice a day - in the morning and in the evening.
Get to know the features of cow feeding in winter.
A cow in excellent condition should receive (per day per 100 kg of live weight):
- 3-4 kg of grass (hay);
- 7-8 kg of silage;
- 5 kg of straw;
- 45 g of concentrates.
- 5 kg of grass (hay);
- 9 kg of silage;
- 2.3 kg of oat or barley straw;
- 1.8 kg of cereals (barley).
Did you know? The term "cattle" comes from the old French "chattel" ( " as in a cage ") . In many regions of the world, cattle remain an indicator of economic wealth.
The objectives of the summer diet are aimed at the daily intake of the required number of feed units, as well as supporting the digestion process. Cows also need more water in the summer. For 1 animal, at least 200 liters of water are needed in hot weather.
- grass and green feed - 45 kg;
- hay –1 kg;
- salt - 50 g.
Diet depending on the direction
For dairy cows, juicy feed is added to the diet to maintain lactation. For cattle in the meat sector, the optimal type of feeding is chosen, the feeding scheme and be sure to add concentrates rich in protein and energy to increase muscle mass.
To enhance lactation, dairy cows need to consume a lot of vegetables, fresh herbs and root crops. Water also has milk-producing properties - it needs at least 40 liters.
Read more about choosing a diet for dairy cows.
- fodder beets - 5 kg;
- carrots - 7 kg;
- gourds - 8 kg;
- greens - 30 kg;
- hay - 1 kg.
Important! To produce more milk, the cow needs to lie a lot. At this time, blood rushes to the udder, which enhances lactation.
Meat cows can be fed using several technologies. The whole diet is based on:
- full feed;
- summer grazing of cows;
- stall maintenance.
- green mass - 60%;
- concentrates - 40%.
Meat and dairy
Cows of meat and dairy type should be provided with root crops, silage, succulent fodder to support lactation and additives for building muscle mass, including squirrels. Protein is necessary for both lactation and growth. On average, a dairy cow will need 2.8-3.2 kg of dry food per 100 kg of live weight. The value of 1 kg of dry matter will be 0.85 energy feed units, each of which should have at least 80% protein.
In feeding cows secrete:
- rest period - dead wood;
Hearing and Lactation
The first 3 months after calving is called a dairy. During this period, the cow gives the maximum amount of milk. It is necessary to increase the amount of feed gradually, by 2 energy feed units per day, until optimal indicators are achieved. For this, feed is added to the diet.
The dry matter rate at the beginning of the period is 15 kg. The ratio will be:
- bulk feed - 60%;
- concentrates - 40%.
For cows with a milk yield of 8-10 kg of milk per day, it is necessary (feed):
- rough - 14 kg (hay and straw);
- juicy - 4 kg;
- green - 5 kg;
- concentrates - 1 kg;
- minerals - 45 g.
Running and dead wood
Stopping milking before the next calving is called a launch. It will last for a week - for cows with medium milk yields or two - for highly productive animals. During this time, the cow is stopped milking and transferred to a dormant state - dead wood.
Important! If the stoppage of lactation was performed medically, then you should not drink the milk of this cow for 48 hours. At this time, the animal receives roughage with a low content of nutrients. The amount of silage should not exceed 8 kg per day. Hay is given according to the needs of the animal. It is very important to exclude juicy foods, as well as calcium from the diet. Water is limited to 1 bucket per day.
Three weeks before calving, you will need to start preparatory feeding, including feed for 25 energy units. Daily nutritional value of the diet is increased by 2 energy units.
