Impact of Helminth Infections on Production of Chickens

Abstract

In free-range poultry rearing systems parasitic infections are frequent with prevalence's up to 100 %, which might reduce productivity. Two hundred and seventy 3-week-old chicks of Rhode Island Red (RIR), Fayoumi and Sonali (a cross of male RIR and female Fayouimi) were divided into 6 groups (2 groups for each breed) consisting of 45 chicks. One group of each breed of chickens was given a routine treatment with levamisole hydrochloride (Poulnec®). All chicks were vaccinated against Newcastle disease, Infectious bronchitis, Infectious bursal disease, Fowl pox, and Fowl cholera. Feed and water were provided ad libitum. Furthermore, all groups had access to an open pen. Naturally, infected seeders hens were then used to induce parasitic infections in all experimental chickens. The non-treated chickens had a significantly higher worm burden compared to the treated chickens. All non-treated chickens showed a significantly lower weight gain compared with the treated chickens at the end of experiment. The average age of point of lay was delayed in the non-treated groups compared to treated groups and in case of Sonali non-treated group it was significantly higher compared to treated group. The average number of eggs and the average egg weight were significantly higher in the treated groups compared to non-treated groups. Economic calculations show that the treatment of hens against parasitic infections in free-range chickens increases the net profit pr hen significantly.

“…Domestic poultry is one of the major primary source of dietary protein in the world, providing both meat and eggs [ 4 ]. Though the productivity of the poultry industry has steadily increased over the years [ 5 ], still, the industry faces serious hurdles in production due to helminth infections caused by nematodes, cestodes and trematodes [ 6 – 8 ].…”

“…In agricultural animals, parasitic diseases result signi cant economic losses annually on a global scale [28]. Domestic poultry, a primary source of dietary protein worldwide through meat and eggs, plays a crucial role in nutrition [29]. Despite advancements in poultry industry productivity, helminth infections caused by nematodes, cestodes, and trematodes remain signi cant challenges to production e ciency [30].…”

“…A previous study revealed that the average weight of flocks of domestic fowls with helminth infections was considerably lower than flocks without such infestations. Domestic poultry is the primary source of dietary protein in the world, providing both meat and eggs (Permin 2020). Particularly in underdeveloped nations, livestock producers sometimes lack to access basic veterinary service and medications, where medicinal plants continue to be utilised in concoction with veterinary pharmaceuticals to cure animal maladies (Tchetan et al 2022).…”
