The impact of the use of Propolis and bee pollen in raising chickens
Today in the world is growing consumption of poultry meat. The increase in consumption of poultry meat is present in developed countries, but also in developing countries. The increase in consumption is attributed to the fact that the poultry meat satisfying the nutritional and dietetic value, has a low cost of production and therefore low market price, has a long tradition of growing in the world, and unlike other types of meat does not have cultural and religious barriers to its consumption. Increase consumption of poultry meat is increasing efforts to improve the quality of meat, and thus protect the health of consumers. 2016 a group of scientists from Zagreb and Osijek conducted a survey on the impact of the addition of Propolis and bee pollen in feeding broiler chickens for the presence of selected bacterial pathogens in cloacal swabs of chickens.
Propolis is a natural bee product that has proven positive health effects. Today it is known more than 200 nutrients contained in propolis. Propolis has bactericidal, antiviral, antifungal, antiprotozoal and antiparasitic, analgesic, anti-inflammatory, antioxidant, anesthetic, anti-tumor and immunostimulating and immunomodulating effects. Bee pollen is a globular cluster, made up of pollen grains mixed with nectar and bee secretions. Today it is known about 250 various chemical substances present in the bee pollen, including carbohydrates, fats, proteins, vitamins, macro- and micro-elements, antibiotics, hormones, enzymes, organic acids and essential oils, and has a bactericidal, antiviral, antifungal , analgesic, anti-inflammatory, antioxidant, anticancer, immunostimulating and immunomodulating effects. Because of these extraordinary impact of Propolis and bee pollen on human health, they decided to observe the effects of their use in the diet of broiler chickens.
For the study was used 200 day-old chickens of provenance Ross 308. Chickens were bred on a farm in the Valpovačka Satnica. The chickens were divided into 5 groups, one control and four experimental. The control group was fed with a mixture without additives, and the experimental group was fed with the mixture in which they added Propolis, bee pollen or Propolis and bee pollen in different proportions. Chickens were observed 42 days.
Research has shown that bee pollen and Propolis have a strong bactericidal effect on bacteria present in the cloaca of broiler chickens, especially for Salmonella sp. Also, research has shown that the addition of Propolis and bee pollen is a simple and natural way of ensuring the quality and health safety of poultry meat, and thus ensures the health of consumers of this meat.
