Poultry Aspergillosis

Image
Aspergillosis is a life-threatening fungal disease occurring in birds of all ages, though it is extremely dangerous for chicks. Aspergillosis is caused by the fungus Aspergillus fumigatus and other species like it and thrives where there is damp, moldy litter, feed, or poorly ventilated poultry housing. Causes • Contaminated feed and water. • Stale bedding or litter materials (wood shavings, straw). • Poor ventilation and damp housing conditions. • Breathing fungal spores that settle into the respiratory tract. Symptoms • Chest tightness or pressure. • Gurgling or rattling sounds within the chest. • Loss of appetite and stunted growth. • Listlessness and ruffled feathers. • High chick mortality. Prevention • Use dry, clean litter and non-moldy feed. • Provide adequate ventilation for poultry houses. • Regularly disinfect poultry equipment and houses. • Avoid overcrowding of birds. • Provide proper nutrition to boost immunity. Treatment There is no very effective cure when...

Poultry Colibacillosis

Image
Colibacillosis is one of the most common bacterial diseases in poultry, caused by Escherichia coli (E. coli). It can affect broilers, layers, and breeders, leading to significant economic losses due to poor growth, reduced egg production, and increased mortality. It can be transmitted horizontally through feces, dust, water, and feed or vertically infected breeders through eggs. Causes of Colibacillosis Causative Agent: Avian pathogenic E. coli (APEC). Predisposing Factors are: • Poor hygiene and contaminated litter, feed, or water. • Poor ventilation and high ammonia levels. • Overcrowding and stress. • Concurrent infections (Newcastle Disease, Infectious Bronchitis, Mycoplasmosis). • Wounds (pecking injuries, infected navels in chicks). Symptoms of Colibacillosis The clinical signs of colibacillosis are: • Loss of appetite (poor feed intake) • Depression, dullness, ruffled feathers • Reduced growth and poor feed conversion in broilers • Drop in egg production in layers •...

Pendulous Crop

Image
Pendulous crop (pendulum, baggy or drop crop) in poultry is a condition where the crop becomes abnormally enlarged, sagging and distended. It usually feels like a water-filled balloon hanging on the chest. Crop is the pouch in the bird’s neck that stores food before digestion.  Causes Of Pendulous Crop There are several reasons that can lead to pendulous crop in poultry birds and some of them are discuss in this article as follow: 1. Overeating or Gorging : When birds consume too much feed especially whole grains or fibrous feed at once can be one of the major causes. The process of digesting the feed will need more water consumption which prompt swelling of the crop.  2. Impacted Crop: Ingestion of foreign materials like long grasses, string, straw, or indigestible material leads to blockage of the crop and prevent proper digestion.  3. Yeast (Candida albicans) and bacteria in spoiled can ferment the feed inside the crop, producing gas and fluid. 4. Weak Crop Muscles...
