Background and Aim: Understanding the phenotypic characteristics of indigenous livestock breeds is essential for their utilization and conservation. This study aimed to characterize indigenous chicken breeds in Indonesia based on phenotypic traits. Materials and Methods: Data on eight qualitative and 12 quantitative traits were recorded for 250 chickens from six breeds: Black Kedu, Gaga, Merawang, Nunukan, Pelung, and Sentul. Data were analyzed using descriptive statistics and one-way analysis of variance to test the effect of breed on observed traits. Moreover, principal component analysis (PCA) was conducted separately for each chicken breed. Data on quantitative traits were subjected to Kaiser-Meyer-Olkin, which was computed to test the sampling adequacy and the pattern of correlation among the traits, and Bathlett's tests were used to assess the validity of the factor analysis of each of the datasets and determine whether the partial correlations among traits were small. Results: We found considerable phenotypic variation in both qualitative and quantitative traits among indigenous chicken breeds. Multicolored plumage (96.40%), wild plumage (39.20%), gold feather flick (51.20%), yellow shank (36.80%), single comb (80.80%), red comb (94.80%), red earlobe (77.60%), and orange eyes (61.60%) were the most common features in the indigenous chickens. In addition, breed had a significant effect on all the quantitative traits that were analyzed (p<0.05). There were higher mean values for all quantitative traits for Pelung chickens than other chickens. In addition, the overall mean values for all quantitative traits in Merawang chicken were intermediate between Pelung chickens and Black Kedu, Gaga, and Nunukan chickens. The PCA showed two principal factors extracted that accounted for 77.80% and 78.38% of the total variance in the original variables for males and females, respectively. Conclusion: In general, body weight and body measurements, except wattle length, were loaded in PC1 as the primary factors responsible for the variation. The phenotypic variation observed in indigenous chickens in Indonesia could provide valuable basic information for the design of selection and genetic improvement programs.
The aim of this study was to determine the effect of fresh and hay alfalfa supplementation in diets on hybrid duck performance. In total 75 hybrid ducks with three treatments and five replications were used in this study. Each replication consisted of five ducks. The feeds were used in the trial consisted of P0 = Basal diets, P1 = Basal diets + 6 % fresh alfalfa supplementation (based on dry matter) and P2 = Basal diets + 6 % alfalfa hay supplementation (based on the dry matter). Water was given ad libitum. Parameters observed were feed intake, body weight gain and feed conversion ratio. This study was arranged with Completely Randomized Design. Data was analyzed with ANOVA (α=5%) using the SPSS version 22 continued with Duncan’s new Multiple Range Test if significant results were found. The results showed that basal diets and fresh alfalfa supplementation significantly affected (P<0.05) to feed intake, body weight gain and feed conversion ratio. Supplementation of 6 % alfalfa fresh resulted the highest body weight gain, followed by control (basal diet) and alfalfa hay. The conclusion from this study was supplementation of 6% alfalfa fresh give a better performance (body weight gain and consumption) than alfalfa hay supplementation, but not for FCR.
Background: There has been great interest in the use of seaweed as a functional feed ingredient for poultry in the last decade. This study aimed to assess the effects of dietary seaweed inclusion on growth performance of broiler chickens by using a systematic review and meta-analysis approach. Methods: A systematic search of published research articles related to seaweed, broiler chickens, and growth performance was conducted using three online databases (Scopus, PubMed, and SciELO). Mean values, standard deviation, and sample size were extracted from each eligible study. The estimated effect size was then quantified using Hedges’ g with a 95% confidence interval (CI). Data were pooled using a fixed-effect model due to the absence of heterogeneity after being pre-checked using the I2 statistic. Results: A total of six studies (nine comparisons) involving 2,257 broiler chickens were accommodated in this study. The seaweed type consisted of seaweed blend, Laminaria japonica, Undaria pinnatifida, Hizikia fusiformis, and Ulva lactuca. The inclusion dose ranged from 2 to 30 g/kg, while the intervention duration ranged from 21 to 42 days. No substantial heterogeneity among studies (I2 = 0.00%) was found for feed intake, body weight gain, and feed conversion ratio. Dietary seaweed had no significant effect on feed intake (Hedges’ g = 0.19; 95% CI = -0.22 to 0.60; P = 0.280). However, broiler chickens fed dietary seaweed had superior body weight gain (Hedges’ g = 0.64; 95% CI = 0.22 to 1.06; P = 0.000) and preferable feed conversion ratio (Hedges’ g = -0.53; 95% CI = -0.95 to -0.11; P = 0.004). Conclusions: The current investigation highlights that dietary seaweed had growth-promoting potency for broiler chickens. However, more research on this issue is still required to build more comprehensive evidence.
Karika (<em>Carica pubesce</em><em>ns</em>)is a typical plant of the Dieng plateau. Previous study showed that <em>Carica</em><em>pubescens</em>contains chemical compound such as flavonoid that play role in analgesic activity. This study was aimed to determine the analgesic activity of etanolic extracts of karika leaves) in vivo using writhing method. The study was conducted on 25 male mice strain Swiss-Webster (20-30 g, 2-3 months) that were randomly divided into 5 groups. Group I was given distilled water 1 mL (p.o) as negative control, group II was given tramadol 50 mg/kgBW (p.o) as positive control, and group III-V received an etanolic extracts of karika leaves in 3 doses, i.e. 20 mg/kgBW, 40 mg/kgBW, and 80 mg/kgBW (p.o), respectively. Acetic acid 0,5% (v/v) was used as pain inductor. The writhe was observed within 1 hour. Data analysis was carried out by using one way ANOVA. The result showed that the ethanol extract of leaves Karika <em>(Carica </em><em>pubescens)</em> have activity as an analgesic at a dose of 20 mg / kg, 40 mg / kg and 80 mg / KgBW (p <0.05), chemically induced, where a dose of 80 mg / KgBW (p.o) produce the most high analgesic activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
