Lameness in chickens (2)
Management factors related to lameness
We have already studied lameness in chickens and its nutritional factors (click to read the introductory article on lameness in chickens (1)). Although the causes of lameness can not be limited to one or two factors, in the following we intend to address some of the most important ones that are related to poultry management. Among them, we can mention the management of the diet and providing food to the bird, light, density, health, etc.
Lack of uniformity or insufficient mixing of diet components, which usually occurs when using vertical mixers, is one of the causes of lameness. In this case, there may be a lack of nutrients (protein) and micronutrients (calcium, phosphorus, zinc, manganese, vitamins, etc.) (read more at this link). When nutritional lameness is observed despite the supply of necessary nutrients, it is necessary to check how the mixer works.
Also, any sudden change in the diet has upset the balance of nutrients in the body of the bird, which can cause deficiencies related to lameness.
However, experts have also suggested management strategies to prevent nutritional lameness in chickens.
1- Applying dietary restrictions in the second week up to 75% of the optional consumption of chickens. However, further reduction of feed can in itself cause nutritional deficiencies and lameness.
2- Feeding in three to four meals is another technical suggestion that can reduce rabbit joint burns, tibial bone scandroplasia and eventually lameness.
3- Using powdered or liquid acid fire that increases the absorption of mineral elements effective in lameness such as calcium, magnesium, zinc, manganese, etc. You can find out more about Fartak Acid Powder Company with E-Side brand here (E-Side link).
4- The use of toxin binder is effective in lameness of chickens. Mycotoxins can cause symptoms such as tibial dyschondroplasia. Fartak Company will help you deal with these fungal toxins by providing E-Pro and E-Pro Plus (links to the contents of the mentioned products).
Any sudden change in diet causes a disturbance in the balance of nutrients in the bird’s body, which leads to deficiencies related to lameness.
Reducing daily exposure and alternating it can reduce mortality and increase the initial growth of chickens. Also, the exposure schedule should be changed gradually over two or three days.
Hall density is very important in the health of chickens and the occurrence of lameness in them. High density reduces the space available for chickens to move, which reduces blood flow to the legs. As a result, the likelihood of anomalies increases.
Density in temperate regions should not exceed 39 kg live weight and in tropical regions should not exceed 30 kg.
Observing the principles of health and timely treatment of diseases is effective in reducing the likelihood of lameness. Although antibiotics may be used as advised by a veterinarian if necessary, today the superiority of using acidic powder or liquid or probiotics in better efficiency for bird health is very important. Fartak helps you provide better and healthier health for your herd by providing quality probiotics under the E-Pro and E-Pro Plus brands (product links should be placed on the names).
Incubation and transfer of chickens to the hall
The quality of day-old chicks can also be one of the factors involved in lameness. For example, low humidity during hatching may cause the chickens to stick to the eggshell.
As a result, chickens with asymmetrical legs or twisted toes are more likely to be seen. High heat and low oxygen during incubation can also cause these complications.
When transporting chickens to the hall, the surface of the cartons should not be polished or the storage temperature should be high. Because it can cause torsion and curvature of the foot.
Salon bed is one of the most important factors in foot health. Improper bedding, smooth surface and cement, especially in the early days of breeding can cause leg sprains and lameness.
Wet litter is a major cause of rabbit joint burns and plantar dermatitis in broilers. At this time, in addition to paying attention to ventilation and room temperature, special attention should be paid to feeding the chickens.
Proper functioning of the gastrointestinal tract improves stool moisture. To achieve this goal, the use of probiotics and acidic powder or liquid fire is recommended.
Lameness and bone abnormalities increase during the warmer months and when the room temperature is high. Because heat stress has a negative effect on the absorption and metabolism of minerals involved in bone structure. Heat also predisposes to the growth of bacteria and infectious diseases associated with the motor organs of chickens.
The age of chickens is directly related to the likelihood of lameness, especially in broilers that are rapidly gaining weight. Because the weight on the skeleton, which has a slower growth rate than other parts of the body, increases.
As mentioned earlier, dietary restriction can reduce the difference in skeletal growth and other organs, reducing the incidence of lameness at older ages.
