FOR YOUR BIRDS
There are direct and indirect consequences to the stress levels to which birds in captivity are exposed. The most important are a decrease in food intake, a greater degree of nutritional imbalance, decrease in fertility, and lower resistance to diseases.
There are direct and indirect consequences to the stress levels to which birds in captivity are exposedTo be more specific, the following are results of stress:
牋牋* A change in the pH of the lower gastro intestinal tract
牋牋* The balance in the ecosystem of the digestive tract is disturbed by a decrease in the positive micro-organisms such as lactobacilli and streptococci (e.g.. L. casei, L. fermentuni, S. faecium) in the favor of pathogens (e.g.. E. coli)
牋牋* The bird becomes highly sensitive to coccidia (eimeria) which increase quickly in the gastro intestinal tract.
Probiotics can however be administered on a more continuous and preventative basis without any negative side effects, especially where digestive problems occur readily. Because the success there of depends on the number of living organisms that the birds consumes.
During times of stress or the use of antibacterial (antibiotics), hormonal changes can occur, causing the pH of the small intestine to rise. This allows existing bad bacteria to take a foothold in the lining of the intestine because of the deterioration of the protective mucus lining. Because of this, the "villi " (little fingers), which normally exist in the small intestine, can be lost. Villi slow the movement of feed as it passes through so that nutrients can be absorbed through the intestinal wall. Increasing good gut bacteria through the use of Probiotics will compete against the bad bacteria, change the pH environment, allow nutrient absorption, and prevent infection. Probiotic treatment has also shown an ability to stimulate appetite.
If you're not inclined to use Probiotics on a daily basis, then at least consider their use immediately following antibiotic treatment and in breading period. When your bird is treated with antibiotics, all bacteria are killed off - good and bad. Treating with Probiotics immediately after the use of antibiotics, help to repopulate the gut with the good bacteria. In many cases, this can ward off a secondary infection, such as E.coli.
The normal bacteria in the gastrointestinal tract are well known for maintaining a healthy, growing condition. It is important that these bacteria be established early in life and be well maintained. If the digestive bacteria are not well maintained the risk of infection and disease is greatly increased. Once the disease organism is established, the bird’s health condition is reduced and sickness, even death, can occur. |
