2019-05-06
Red rocky lick brick significant efficacy: 1: Improve animal health and reduce morbidity (e. g., increase pregnancy rate in the initial stage, mastitis, hoof disease, retention of the placenta, etc.); 2: increase water intake, increase appetite, increase weight and milk production; 3: enhance fertility and fetal health; 4: improve the quality of fur, improve food digestion, improve feed utilization;
Beef cattle in different growth stages, different growth rates and different environmental conditions, the demand for a variety of nutrients is very different. If the nutritional needs of beef cattle can be fully met, the production potential can be maximized. Beef cattle need nutrients including: water, energy, protein, minerals and vitamins.
1. The need for water for beef cattle
The function of water
Water is an important component of animal body. Bovine body water content generally accounts for body weight55～65%The water content of beef is about64%. Water participates in the dissolution, absorption, transportation and metabolism of various nutrients in the body. The heat capacity of water is large and the heat of evaporation is high, which is of great significance for maintaining constant body temperature.
Effect of water shortage on cattle
Water is the cheapest, most accessible and often overlooked important nutrient compared to other nutrients. Cattle lack of water will cause metabolic disorders, digestion and absorption disorders, growth slowed down. The harm of animals not getting water is greater than the harm of not getting feed. Hungry animals can consume all the body's fat and50%above the protein while surviving, but when the animal is dehydrated5%When appetite decreases;10%when physiological metabolic disorders;Water shortage20%at the time of death.
Sources and requirements of water
Cattle need water from drinking water, feed water and metabolic water,But it depends mainly on drinking water.
The water requirement of beef cattle is affected by weight gain rate, activity, diet type, feed intake and ambient temperature. Usually every food intake1kgDry matter, calves need6-7kgWater, adult cattle need3-5kgWater. General250-450kgFattening cattle at ambient temperature10The amount of drinking water25―35kgBetween, to ensure fresh, clean and adequate drinking water.
2. Beef cattle need for dry matter
The concept of dry matter and dry matter intake
Dry matter is the material in the feed ingredients other than water. Feed samples in105The weight lost is the moisture content, and the remaining weight is the weight of dry matter. general use%said, such as corn silage moisture content65%, then the dry matter content is35%.
Dry matter intake refers to the amount of beef cattle in24The total amount of dry matter in the feed taken within hours. The English abbreviation isDMI,kg/day said. This is one of the most important indicators in beef cattle breeding, and it is also the premise of scientific preparation of beef cattle feed. It determines the amount of nutrients needed to maintain animal health and production. Inadequate supply can limit animal performance and affect health;Oversupply will lead to increased feed costs and waste.
Dry Matter Intake of Beef Cattle
growth and fattening cattle formula:DMI=0.062× Weight0.75 (1.5296 0.0037× Weight)× Daily gain
pregnancy cow formula:DMI=0.062× Weight0.75 (0.790 0.05587× days of pregnancy)
lactation cow formula:DMI=0.062× Weight0.75 (0.45× Standard milk)
3. The need for energy of beef cattle
Source of Energy
Animal organism for life-sustaining activities(Such as heart beat, lung breathing, blood circulation and maintenance of body temperature)and production activities(such as weight gain, reproduction and lactation)They all need to consume a certain amount of energy.
The energy consumed by the body comes from the feed, and the carbohydrates, fats and proteins in the feed can provide energy. But the main source is carbohydrates, including sugars, starch, cellulose and hemicellulose.
The amount of protein required
Crude protein requirements for growing-fattening cattle: crude protein requirements for maintenance(grams/Day)=5.5W0.75
Crude protein required for weight gain(grams/Day)=D.W(168.07-0.16869W 0.0001633W2)×(1.12-0.1233D.W)/0.34 (Note: in the formula: ΔWfor daily gain).
In actual feeding, weight300About kilograms of shelf cattle, the proportion of protein feed in the diet, can account10%～13%. Later, with the increase of body weight, the content of protein feed in the diet gradually decreased. By the end of fattening, the content of protein feed, accounting10%You can.
Effects of protein deficiency or excess on production and health
Insufficient protein supply: reduced digestive function, reduced feed intake, reduced feed conversion efficiency;Growth retardation, weight loss, structural and functional abnormalities of tissues and organs;Disease resistance decreased, prone to infectious and metabolic diseases.
Excessive protein supply: increased liver and kidney load affects the health of cattle, resulting in protein poisoning;A large amount of energy is used for abnormal metabolism and excreted in urine, which reduces energy utilization efficiency.
Lodge nutrition licking brick is a pure imported product and has obtained the EU green free sales certificate and product organic certificate. The production process of Lodge licking brick has reached the international leading level and is sold well in more than 50 countries in the world. Its hardness is good and it is not afraid of wind, sun and rain. It is produced by nanotechnology, high temperature pressing and low pressure packaging and is the world's top product.
Red Rocky Lick Bricks are specially designed for ruminants. The balanced nutritional formula can promote the growth and development of cattle, increase milk production, increase body weight and increase reproduction rate. Magnesium, iron, cobalt, iodine, manganese, zinc, selenium, sodium, copper and other elements interact and participate in the metabolism of the body, so it has a great effect and influence on the health, weight gain, milk production, reproduction and other aspects of cattle, and finally brings breeding benefits.
red rocky lick brick significant efficacy:
1: Improve animal health and reduce morbidity (e. g., increase pregnancy rate in the initial stage, mastitis, hoof disease, retention of the placenta, etc.);
2: increase water intake, increase appetite, increase weight and milk production;
3: enhance fertility and fetal health;
4: improve the quality of fur, improve food digestion, improve feed utilization;
the correct use of licking bricks:
1. The position of the licking brick should not be raised. The best position is 30-50cm from the ground. It is best to place it in a special licking brick box.
2. Livestock should lick the bricks as much as possible. At least one lick brick per 5-10 adult cows;
3. The surface of the lick brick must be kept clean. If there is dirt on the surface of the lick brick, it will affect the animals.LickSituation.
4, licking bricks should be placed as far as possible in the water source and where livestock often gather; to keep the water source clean.
5, the use of licking brick cattle can not add salt, or feed salt can not be higher than 0.1;
6, the time the herd licks the bricks is also important.
