How to treat diarrhea in laying hens? Prevention and treatment methods and key points for medication
Due to physiological needs, laying hens greatly increase their feed intake and water consumption; at this time, material metabolism is enhanced, body heat radiation increases, the house temperature rises, and water consumption increases even more, so they often pass loose droppings. So, how to treat diarrhea in laying hens?
1. How to treat diarrhea in laying hens?
Individual laying hens with severe diarrhea can be given norfloxacin or gentamicin orally; for the whole flock, use Bacillus Vanguard at one bottle (300 jin of water) + Zhili San (200 jin/bag) mixed into the feed, for 5 consecutive days. In addition, attention must be paid to feeding management and environmental hygiene; the house is required to be dry and well ventilated, with stable temperature, moderate density, clean equipment, and a reasonable feed formula.
2. What are the causes of diarrhea in laying hens?
1. Feed factors
Some chicken farmers, in order to improve the palatability of the feed, enhance the chickens' appetite and supplement salt in the body, often increase the salt content in the daily ration of laying hens; added to the fact that the feed itself sometimes has a relatively high salt content, the chickens' water consumption surges after eating, which can all lead to thin droppings. In addition, a relatively high magnesium content in dicalcium phosphate and limestone powder in the feed can also lead to thin droppings; this situation rarely occurs before the laying hens' feed is changed, and mostly occurs after the feed change.
2. Climatic reasons
When the outside temperature is high, cooling by drinking water is the main means for laying hens to maintain a constant body temperature, but due to their physiological factors, after the water enters the blood circulation, most of it can only be excreted from the cloaca, thus causing thin droppings.
3. Drug factors
Long-term and large-scale abuse of drugs to prevent disease, on the one hand, increases the cost of raising chickens; secondly, it increases the emergence of drug-resistant strains, which is not conducive to treatment; furthermore, it destroys the normal balance in the chickens' bodies, sensitive strains are inhibited, drug-resistant strains multiply in large numbers, and severe superinfection occurs, leading to long-term stubborn diarrhea.
4. Stress factors
Sudden climate changes, sudden feed changes, environmental pollution, moving to another pen, noise, changes of keepers, and other stimuli to the chickens can cause diarrhea.
5. Nutritional imbalance
Excess protein while essential amino acids such as lysine are insufficient, or trace elements being unbalanced or insufficient, or lacking, can all lead to metabolic disorders, indigestion, and diarrhea.
6. Rearing environment and conditions
For example, darkness and dampness, excessively low temperature, poor hygiene, excessive density, poor ventilation, and so on lead to insufficient oxygen intake by the body, congestion in various tissues and organs, decreased function, and diarrhea.
The above treatment methods for diarrhea in laying hens are for everyone's reference only. If a severe case of diarrhea is encountered, it is best to find a professional veterinarian for treatment.
