Quantitative characteristic of Indonesian native chickens at the age of 4 months

Abstract

<p class="MDPI17abstract"><strong>Objective: </strong>Native chickens (Kampung, Sentul, and Merawang) have great potential to be developed as both meat and egg producers. Quantitative data about native chickens are not widely known. The purpose of this research was to determine the quantitative characteristics of Native Chickens aged 1 month, 2 months, 3 months and 4 months.</p><p class="MDPI17abstract"><strong>Methods: </strong>The research material is native chickens. The method used was an 82 sample in each strain and a total of 246 samples. The data collected is of a quantitative traits. Quantitative traits are traits that are influenced by multiple gene pairs, can be measured, and are heavily influenced by environmental factors. Data collected were analyzed using the average difference test (t-test). The average value vector of body measurements of chicken lines was analyzed using the T2-Hotelling statistical test. Main Component Analysis statistical test to identify the shape and size characteristics of each chicken strain. Data processing was assisted by using Minitab statistical software version 18.<strong></strong></p><p class="MDPI17abstract"><strong>Results: </strong>The results of this study showed that body weight, weight gain and body size measurements of Kampung chicken were significantly different (P <0.05) higher than Sentul chicken and Merawang chickens. The identifier of the size of the Kampung chicken is the width of the chest, while the identifier of the shape is the length of the back. The identifier of Sentul chicken size is chest length, while the tibia is long. The characteristic of Merawang chicken is the length of the tibia, while the character of the shape is the wing length.<strong></strong></p><p><strong>Conclusions: </strong>Quantitative characteristics (body weight, weight gain and body size measurements) at the age of 4 months Kampung chickens more heavily than Sentul chicken and Merawang chicken.</p>

Comparison of Productivity of Sentul and Kampung Chickens until the Age of 3 Months in the First Generation Selection Population (G1)

“…The body weight gain of DOC-1 month, 1-2 months, 2-3 months Kampung chickens, respectively were 364,65±23,94 g, 381,00±54,00 g, and 499,86±45,03 g. The average body weight gain of Kampung chickens from the age of DOC-1 month, 1-2 months, 2-3 months this study was higher than the results of Kestaria et al (2016), which states that the increase in the average body weight gain of Kampung chickens aged DOC-1 month was 2250.30 g and 1-2 months old was 322.93 g, and the results of Irmaya et al (2021), which stated that the average body weight gain of Kampung chickens aged 2-3 months was 372.87±76.31 g.…”

Morphometric characterization and effect of growth hormone (GH) gene polymorphism on growth traits of Kerinci duck (Anas platyrhynchos)

“…This difference was due to the body skeleton of male Kerinci ducks being larger than female Kerinci ducks. This is the opinion [17][18][19], who states that an animal's size of body is influenced by the size of the animal's body frame. The longer the skeleton is in normal size, the more muscle attached to it, resulting in a larger carcass piece [20].…”

Phenotype Diversity and Gene Myostatin (MSTN) of Bangkok Chicken using PCR-RFLP

“…Pagala et al (2019) stated that the average DOC weight of male and female Bangkok chicken was 36,76 g and 37 g. KUB chickens was 31.50 g and 30.12 g (Suryana, 2017). The DOC weights of Kampung, Sentul and KUB chickens were 26.38 g, 33.85 g, and 31.06 g (Irmaya et al, 2021).…”
