Abstract

A study was conducted to evaluate the efficacy of neem, girawa leaves meal, and garlic for layer hens on performances and egg quality parameters. A total of 128 bovans brown layer hens with uniform body weight (BW) were randomly distributed to 4 treatments, each with 4 replications in a completely randomized design (CRD). The treatments consisted of a commercial diet without additives (T1), and the remaining groups received commercial diet with neem leaf meal (T2), girawa leaf meal (T3), and garlic powder (T4) at 2.5% level of inclusion. Performance parameters such as hen-day egg production, egg weight, feed intake, and internal and external egg qualities were evaluated for the laying hens. The results showed that the highest feed intake was reported in T2 (117.77 g/hen) and T4 (117.12 g/hen), while the lowest was reported in T3 (108.20 g/hen) compared to T1 (110.51 g/hen). Neem had the highest (P < 0.05) hen-day egg production (92.45%), followed by garlic (89.78%), and the least hen-day egg production was recorded in girawa (83.86%) compared to control (87.4%). The egg mass was highest for T2, while T1 and T3 had the lowest. No significant difference was observed in egg weight, shell thickness, shell weight, albumin height, albumin weight, yolk weight, yolk height, and yolk diameter. However, egg length and yolk color were significantly (P < 0.05) higher in T2. Therefore, it was concluded that neem leaf meal can be recommended in this study, and it has a good phytogenic feed additive for layer performance and egg qualities.

期刊介绍： The Journal of Applied Poultry Research (JAPR) publishes original research reports, field reports, and reviews on breeding, hatching, health and disease, layer management, meat bird processing and products, meat bird management, microbiology, food safety, nutrition, environment, sanitation, welfare, and economics. As of January 2020, JAPR will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers. The readers of JAPR are in education, extension, industry, and government, including research, teaching, administration, veterinary medicine, management, production, quality assurance, product development, and technical services. Nutritionists, breeder flock supervisors, production managers, microbiologists, laboratory personnel, food safety and sanitation managers, poultry processing managers, feed manufacturers, and egg producers use JAPR to keep up with current applied poultry research.
