Abstract

The community's growing demand for chicken meat as an animal protein source has presented farmers with the challenge to alter the care of broiler chickens by using high cage density. The aim of this study is to investigate the effect of diet supplementation with encapsulated extract of kenikir (Cosmos caudatus) and bitter (Andrographis paniculata) extracts on broiler diet to growth perfor-mance, immunity status, and carcass proportion. A total of 370 day-old Cobb broiler chicks, weighing 45.25 ± 0.89 g, were divided into five groups: T0: control, basal diet + density 10 chicks/m2, T1: basal diet + density 16 chicks/m2, T2: basal diet + density 16 chicks/m2 + Cosmos caudatus 1 g/kg feed, T3: basal feed + density 16 chicks/m2 + Andrographis paniculata 1 g/kg feed, T4: basal feed + density 16 chicks/m2 + Cosmos caudatus 0.5 g/kg feed + Andrographis paniculata 0.5 g/kg feed). At the end of the study, the blood sample and internal organ were collected to further analysis. The final weights of groups T2, T3, and T4 were better than T0 and T1, while T1 has the lowest weight among the other groups. Chicks in T0, T2, T3 and T4 had lower PDW levels compared to T1. Chicks in T4 have a high-er jejunum villi height compared to T0, T1, T2 and T3 groups. The treatments did not affect the small intestine and giblets relative organ wights (P>0.05). The group of T0, T2, T3, and T4 have a fewer duo-denum lesion compared to T1. The group of T2, T3, and T4 have a better structure in jejunum cells compared to T0 and T1. Lesion score of Bursa Fabricius and spleen were greater in T3 and T4 com-pared to T0, T1 and T2 groups. And T1 have the lowest ND antibody compared to other groups. In con-clusion, giving encapsulation of kenikir (Cosmos caudatus) and bitter (Andrographis paniculata) ex-tracts on broiler diet can improve production performance and immune status of broiler chickens.

Abstract

This study evaluated the effects of different frequencies of Spirulina platensis S. platensis )supplementation on blood parameters, protein digestibility, fecal characteristics, egg quality, and production performance in laying hens. A total of 224 ISA Brown hens (55 weeks old, BW ±1907 g) were assigned to four groups: T0 (control, basal feed), T1 (0.5% S. platensis daily), T2 (0.5% every other day), and T3 (0.5% twice a week). The trial lasted for eight weeks, with weekly measurements of feed intake, egg production, and egg quality. Blood was collected at the end of the experiment to assess hematological profiles, while fecal samples were analyzed for protein digestibility and nitrogen excretion. Results showed that T3 and T4 significantly increased red blood cell count, hemoglobin concentration, hematocrit value, and leukocyte count compared to the control (P<0.05). Compared to T0, nitrogen retention and protein digestibility coefficients (%) in T1, T2, and T3 were significantly different (P<0.05). Excretory nitrogen levels in the treatment groups (T1, T2, and T3) were substantial-ly lower than those in T0 (P<0.05). Compared to T0, fecal ammonia levels in the treatment groups (T1, T2, and T3) were lower. The water content in T3 was significantly higher than that in T2 (P<0.05). Haugh Unit values in T1 and T2 were significantly higher than those in T0 and T3 (P<0.05). HDP at weeks 6 and 12 in T1, T2, and T3 were significantly higher than those in T0 (P<0.05). In conclusion, S. platensis supplementation enhanced hematological status, nutrient utilization, fecal characteristics, egg quality, and production performance. Twice-weekly supplementation (T3) was as effective as the more frequent regimens, suggesting a practical and cost cost-efficient strategy for laying hens.
