How to Prevent Heat Stress with Vitamin C Supplementation

Question:

Dear Fenanza Team

 

 I am Irvan from Bandung, I have a layer farm using self-mixing for feed production. Recently, I have been seeing my chickens do for 'panting' and decline in egg production and depletion of birds. I have been looking for any information from my community and farm technical people, they recommended to provide anti stress / vitamin C, but after I tried, the results were less than optimal because the production was low and sometimes there were thin eggs. Please provide a solution to resolve that issue, thank you. Regards

 

Answer: 

Dear Mr. Irvan, we thank you for the question given to Fenanza. We appreciate that questions given to the Fenanza team. Relate to the problem that you have told fro us, the condition is one of the symptoms of heat stress in animal. Heat stress is a condition in which chickens experience stress caused by body heat that exceeding the maximum limit (41- 42 oC). This is happened because of the biological response of chickens that changes the temperature in the body. The chicken tries to dispose of heat through the process of panting because the chicken do not have sweat glands, so the heat removal process is carried out through its beak. However, Panting is one of ways of dissipating heat, because chickens can also lose heat through the radiation, conduction and convection process. The response is due to laying hens are warm-blooded animal (homeothermic) which must adapt to the temperature of the environment.

There are two types of heat stress, such an environmental factors that are often caused by temperature, humidity and geography. When the temperature tends to be high, it automatically affects the corticosterone, glucorticoids, cortisol and adrenaline hormones which results in high body temperature. The second type factors caused by human such as density of the cage, the transportation process, time of the handling of livestock. Environmental factors, especially high temperatures, are the most common cause of heat stress among chicken farmer, both broilers and laying eggs.

In fact, heat stress is very common in Indonesia, given to the geographical conditions & tropical climate which results in relatively higher temperatures. Unfortunately, some breeders have not paid more attention to this cases, some studies reported that heat stress caused: 1). Decreased feed consumption up to 16.4%, body weight 32.6%, and increasing FCR to 25.6% so that it has a direct impact on production performance, 2). High drinking water consumption which resulting wet-feces and watery, 3). Decreased lymphocytes (white blood cells) which cause a decrease in immunity, easily get sick, poor antibodies, until getting death, 4. Decreased feed digestion and plasma proteins which have an impact on poor egg quality, such as thin shells & small eggs.

Overcoming heat stress can be done in various ways, including improving the condition of the cage, lowering the density, and providing anti stress supplementation. In emergency condition, anti stress supplementation such as vitamin C (ascorbic acid) is highly recommended because it has a dual role at the same time, because it can prevent and cope with heat stress. In stressful conditions, livestock produce high free radicals, so giving vitamin C is needed as an antioxidant and photoprotectant.

Relate to your question, that previously provided antistress supplementation but the results were not optimal. That can happen because of the quality of the product used. We recommend using HALOR C as antistress supplementation for livestock. HALOR C is a vitamin C crystal using coated process which has achieved perfect coating, ideal post-processing resistance and excellent bioavailability, and shows significant advantages over ordinary vitamin C. The ‘coated ’technology or the capsules used makes ≥90% of the protected vitamin C content inside, so it will not be damaged/ reduced before it enters the target organ/ digestive system of animal.

The best use of HALOR C is by mixing into the feed. During the stress of animal, please use 200 g/ MT of feed to get maximum results. However, in daily use as a preventive measure, you can use 50 g/ MT of feed. Hopefully it can be the right solution for your farm in the future. For further information, don't be hesitate to contact the Fenanza Team. Thank you.
