Phytogenic Feed Additives as An Alternative to Antibiotic Growth Promoters in Poultry Nutrition

Phytoadditives in animal nutrition have attracted a lot of attention for their potential role as alternatives to antibiotic growth promoters. Phytoadditives are feed additives originated from plants or botanicals that are used in poultry nutrition. This chapter provides an overview about the potency of alternative additive from plants as a basis for exploring it as a phytoadditive for poultry. These substances are derived from herbs, spices, and other plants and their extracts. They are natural, less toxic, residue free and ideal feed additives for poultry when compared to synthetic antibiotics. There efficacy of phytogenic applications in poultry nutrition depends on several factors, such as composition and feed inclusion level of phytogenic preparations, bird genetics, and overall diet composition. Addition of 100 mg/kg feed essential oils consist of carvacrol, thymol and limonene in matrix encapsulation improved performance and apparent ideal digestibility of nutrients of broiler chickens. Besides enhancing performance, phytogenic also has antioxidant, the effects of which are associated with essential oils (EOs) and their components. Administration of eucalyptus and peppermint oil blends by oral (0.25 ml/L drinking water) and spray route (0.1 ml/20 ml water) reduced Newcastle disease infection in broilers. Phytoadditives have antimicrobial, antifungal, antiviral, antitoxigenic, antiparasitic and insecticidal properties. The benefits of using phytoadditives in poultry nutrition are increased feed intake, stimulation of digestion, increased growth performance, reduced incidence of disease, improved reproductive parameters, feed efficiency, profitability. Based on the latest scientific findings presented in this chapter, the following main conclusions have been drawn that phytomolecule and that bioactives have potential to be developed as an alternative additive for poultry, and that promote health

Penggunaan Ekstrak Daun Eceng Gondook (Eichornia crassipes) Sebagai Pengawet Terhadap Kualitas dan Kuantitas Telur Ayam Ras

This research was conducted for 3 months in the laboratory of the Department of Animal Husbandry, State University of Gorontalo. This study used an egg sample of 240 eggs of purebred chickens. Eggs were divided into 4 treatments, each treatment was repeated 3 times. A0 = 0% (eggs without treatment), A1 = 10% (eggs soaked at 10% level of water hyacinth leaf extract), A2 = 20% (eggs soaked at 20% level of water hyacinth leaf extract), A3 = 30% (eggs by immersing 30% level of water hyacinth leaf extract). B0 (1 day old egg), B1 (14 day old egg), B2 (21 day old egg), B3 (28 day old egg). The research was conducted by measuring egg weight, air voids, HU value, egg yolk color, and taste. Flavor. Data were analyzed using a completely randomized design (CRD), and further tests were carried out using Duncan's test. The results of this study showed that the effect of tannin content on the level of 20% water hyacinth leaf extract was able to maintain egg quality compared to eggs that were not given treatment (control). Because the tannin solution derived from water hyacinth leaves is able to cover the egg shell pores properly

Fitokimia Daun Kemangi (Ocimum x citriodorum L.) dan Pengaruhnya Sebagai Water Additive Terhadap Kecernaan Nutrien Pakan Ayam Broiler

The study was conducted to analyze the phytochemicals of basil leaves (Ocimum x citriodorum L.)and to evaluate the effect of basil leaves juice as an additive on nutrient digestibility of broilerchicken diet. This study used 20 male broilers (35 days old). The research parameters werephytochemical, proximate, and digestibility analysis. The data of basil leaves phytochemical andproximate analysis were analyzed using descriptive analysis. The digestibility were analyzed usinga Completely Randomized Design (CRD) by 4 treatments and 5 replications. The research wasconducted for 10 days consisting of 7 days for maintenance period and 3 days for total collectionperiod. The digestibility treatments consisted of 0 mL, 10 mL, 20 mL, and 30 mL basil leaves juice/Ldrinking water. The results showed that giving basil leaves juice had a good effect on nutrientdigestibility of broiler chickens and could be used up to 20 mL/L in drinking water
