Diarrhea in calves: Using pronutrients to control it
The following article is intended to inform producers the benefits of using pronutrients in the diet of calves.
Reasons for the change to natural products.
1. – The Trend of legislation to remove certain substances used in animal feed (antibiotic growth promoters, coccidiostats).
2. – The search of alternatives to maintain growth performance while meeting the legislative requirements and consumer.
Alternative: application of nutritional supplements to enhance and maintain the health of the animal without affecting and to improve the initial conditions of the animal.
The newborn calf is unable to digest solid food because their digestive system works like an animal in a single stomach, 60% of the system is occupied by the abomasum, which is the only developed and functional stomach. The calf can start eating solids when you start developing the first stomach, this occurs only after one or two months of age, depending on the received power.
Availability is important and early consumption of solid food to encourage rumen development and calf have a healthy, ready to wean. In a first adult animal stomach or rumen, comes to occupy 80% of total capacity of 4 stomachs.
The calf learns to voluntarily consume solid food at 5 months of age, reaching this age are known to consume about 600 to 1000 liters of milk, this not only reduces the milk which can be sold, but the prolonged breastfeeding is a factor that slows the growth of the calf stomachs.
After weaning, the calf stomachs quickly complete their development and operation, in order to digest solid foods. If supply of low nutritional foods, they can not properly digest, which would cause nutritional deficiency in addition, by not provide the nutrients required for normal growth and development of animals.
Diarrhea is usually from 12 hours postpartum until the first 2 months of life. The highest incidence was recorded in the first week of life. Clinically, it is characterized by excretion and profuse watery stools, progressive dehydration, acidosis and, in severe cases, death within days, mainly when there are primary or secondary bacterial infections by enterotoxemias.
While the causes of diarrhea can be infectious, nutritional or toxic, infectious diarrhea are the most common agents involved are diverse and can be viral, bacterial or parasitic. Diarrhea caused by infection primarily affecting calves in their first 45-60 days of life, during monogastric condition. That is why the supply valuable pronutrients early and reduce the rate of diarrhea and use their characteristics to pronutrients intestinal conditioner, generating proper assimilation of nutrients.
Another important point is the natural way to prevent calves from bacterial infections or viral type.
Then attached a table illustrating the use of pronutrients compared to animals treated with antibiotics.
Trial location: India.
Type of test: Controlled, randomized, parallel.
Control: untreated food, feed antibiotic (oxytetracycline 5-6 mg / KPV).
Animals: Calves of 50-90 kg. Animal growth.
Product used: pronutrients
Dosage: pronutrients 10 g / day, 6.5 mg oxytetracycline / KPV.
As we can see the use in calves pronutrients allows us to efficiently reduce diarrhea in calves early.
