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

The study was conducted to evaluate the effect of dietary supplementation of red tomato extract (RTE) on intestinal microflora, fat digestibility, body fat (meat fat mass, abdominal fat), and performances of male tegal duck. One hundred birds of male tegal ducks of 3 weeks old (initial body weight was 507.74±31.86 g) were randomly divided into 4 treatments with 5 replications (5 birds each) in a completely randomized design. Dietary treatments were basal diet without RTE as a control (T0), basal diet added with 0.10% RTE (T1), basal diet added with 0.15% RTE (T2) and basal diet added with 0.20% RTE (T3). Parameters measured were lactic acid bacteria (LAB), coliform, intestinal pH, fat digestibility, meat fat mass, abdominal fat, blood concentrations of malondialdehyde (MDA) and superoxide dismutase (SOD), body weight gain (BWG), carcass weight, feed consumption, and feed conversion ratio (FCR). Data were subjected to analysis of variance and continued to Duncan multiple range test when the treatment indicated significant (p<0.05) effect. Supplementation of RTE at higher level significanly (p<0.05) increased lactic acid bacteria (LAB), concentration of superoxide dismutase (SOD), carcass weight and body weight gain (BWG), while fat digestibility, meat fat mass, abdominal fat, malondialdehyde (MDA), intestinal pH, coliform counts and feed conversion ratio decreased (p<0.05), as compared to control. Feed consumption tended to decrease but not significant (p>0.05). In conclusion, feeding red tomato extract at a level of 0.20% (T3) can be categorized as effective in improving intestinal bacterial balance, body fat, increasing superoxide dismutase (SOD), an antioxidant enzyme, and performances of male tegal duck.

Abstract

An experiment was conducted to estimate growth parameters for commercial broiler chickens in Indonesia. The data was collected from July 2021 to June 2022. A total of 1,570 samples consisting of four strains of broiler chickens were collected from 74 houses. The samples were daily weighed from 0 to 7 days of age, and they were weekly weighed from 1 to 5 weeks of age. A nonlinear Gompertz growth model was fitted to the observed body weights (BW). The results for five growth parameters were as follows: the asymptotic value (A) of the mature live weight ranged from 3.733 to 5.044 kg; the turning point of growth (B) ranged from 4.499 to 4.561; the value growth rate constant (K) ranged from 0.049 to 0.059 kg/week; Inflection points in ranged from 25.292 – 30.970 days, and 1.373 – 1.855 kg for inflection age (IA) and inflection weight (IW), respectively. The model was an excellent fit for the growth data in the commercial broiler with a low Akaike information criterion (AIC), and high coeffi-cient determination (R2).

Abstract

This study aimed to evaluate the effects of encapsulation of Medinilla speciosa fruit extract in feed on the oxidative status, amino acid digestibility, and performance of broiler chickens raised at high stocking densities. The M. speciosa contains polyphenols, flavonoids, tannins, and saponins. This study used 290 unsexed Ross strain broiler chicks aged 8 days, with an average body weight of 196.01 ± 1.12 g. M. speciosa fruit extract (MSFE) and encapsulated M. speciosa fruit extract (EMSFE) were used as sources of phytobiotics. This study was designed with four treatments and five replicates. The treatments tested were T0: normal density of 10 birds/m² without MSFE or EMSFE; T1: high density of 16 birds/m² without MSFE or EMSFE; T2: high density of 16 birds/m² + 0.08% MSFE; and T3: high density of 16 birds/m² + 0.08% EMSFE. The results showed that the addition of MSFE and EMSFE to the diet had a significant effect (P<0.05) on performance (feed intake, daily weight gain, and feed conversion ratio), protein and amino acid digestibility, oxidative status (malondialdehyde, superoxide dismutase, and glutathione peroxidase), as well as total lactic acid bacteria, Escherichia coli, and small intestine pH. The conclusion is that incorporating 0.08% encapsulation of M. speciosa fruit extract notably enhances the overall health, absorption of essential amino acids, and growth of broiler chickens raised in high-density conditions, suggesting its promise as an effective phytobiotic feed additive.

Abstract

Indonesian Indigenous poultry originated from the central part of Java Island, called Kedu chick-en, given diet added with inulin of dahlia tuber extract (IDTE) to evaluate body resistance and protein deposition. The experimental animals were 150 birds of 14-day-old Kedu chicken (initial body weight was 148 ± 16.4 g) until 12 weeks old. Dietary treatments were T1: farmer’s diet with protein concen-trate; T2: T1 + 1.2% inulin of IDTE, and T3: modified diet with common protein sources + 1.2% IDTE. A completely randomized design was assigned with 3 treatments (5 replications with 10 birds each). Parameters observed were rate of passage, protein and fiber digestibilites, Nitrogen (N) and Cal-cium (Ca) retentions, body resistance (plasma concentration of corticosterone/CTC, level of immuno-globulin A/IgA, and heterophyl-lymphocyte/H/L ratio), protein metabolism (fecal Nτ–methylhistidine/Nτ–MH and muscle protein mass), feeds consumption, feed conversion ratio (FCR), and body weight gain (BWG). Analysis of variance and Duncan’s test were applied to analyze data. Rate of passage, N and Ca retentions, BWG, IgA level, and muscle protein mass increased; in contrast, FCR, fecal Nτ–MH, and plasma CTC decreased due to the feeding effect of the T3 diet. All parameters, except IgA level, between treatment T1 and T2 indicated similar values. It can be concluded that a modified diet added with IDTE (T3) can modulate the increase in N retention and immune status, with the decrease in muscle protein degradation indicated by low fecal Nτ–MH excretion, and finally, brings about a bet-ter growth rate, with higher muscle protein deposition.
