Abstract
This study was conducted to determine the effect of herbals on the production performance and gastrointestinal health of layer hens. There were 50 layer hens used and assigned randomly into two different types of diets namely, basal diet (T0) and basal diet+3ml herbals/1000g ration (T1) with each treatment consisting of 25 birds. Meanwhile, the herbals supplemented into the poultry feed consisted of tumeric, sambiloto leaves, soursop leaves, ginger, and lemongrass. Consequently, the T-test results showed that supplementation of herbals on treatment 1 (T1) statistically had no significant difference with treatment control (T0). The study concluded that the herbal mix could be used as a feed supplementation in a layer basal diet.
Highlights
The use of antibiotic growth promoters increases the antimicrobial resistance in consumers of poultry products
Herbals are medicinal plants that contain certain bioactive compounds and can be used in the livestock industry as feed additives [1]. They can be used as natural growth promoters (NGPs) developed as feed supplements to increase immunity, production performance, and gastrointestinal health [2]
Feed consumption was cumulatively calculated by summing the total weekly consumption of initial to the end of maintenance
Summary
The use of antibiotic growth promoters increases the antimicrobial resistance in consumers of poultry products. The layer hen industries are looking for other additives that are safer for consumers. Herbals are medicinal plants that contain certain bioactive compounds and can be used in the livestock industry as feed additives [1]. They can be used as natural growth promoters (NGPs) developed as feed supplements to increase immunity, production performance, and gastrointestinal health [2]. Herbal mixture supplementation hopefully can improve the histomorphology and microflora of the small intestine. The herbal mix containing 2.5% of turmeric and garlic was reported to improve duodenal histomorphology and stimulate growth performance [2]. Herbals as feed additives to layer hens were expected to improve intestinal histomorphology. An in-depth study is needed to prove its effectiveness in intestinal health
