Abstract

The study examined the association between TLR1A gene polymorphism in exon 4 and the performance of Gray Sentul chickens. Conducted at the Jatiwangi Poultry Breeding Development Center. DNA from 30 males and 30 females was analyzed using PCR and sequencing to identify Single Nucleotide Polymorphism (SNPs). Data processing employed BioEdit and MEGA 11. Results revealed five mutations in males (g.775T>C, g.844 T>A, g.858C>T, g.983C>T, and g.1163G>A) and three in females (g.721G>A, g.983C>T and g.1163G>A). Males showed higher body weights, with optimal growth at 1–2 months. Peak egg production occurred at 41 weeks (HDP 44.97%), and the highest egg weight (46.93 g) at 55 weeks. Specific SNPs associated with performance traits include g.775T>C for body weight in males, g.1163G>A for body weight in females and egg production, and g.721G>A and g.983C>T for egg weight. This study concludes that the TLR1A gene can be used as a genetic marker to improve the performance of grey Sentul chickens.

Abstract

The success indicators for the hatchery program in the management of sentul chicken breeding at the Regional Technical Implementation Unit (UPTD) of the Poultry Breeding Development Center (BPPTU) in Jatiwangi are fertility, hatchability, and salable chicks. UPTD BPPTU Jatiwangi is an institution responsible for the development and improvement of local poultry breeds under the supervision of the Department of Food Security and Animal Husbandry (DKPP) of West Java Province. This research aims to determine the fertility, hatchability, and production of salable chicks from Sentul chickens at BPPTU Jatiwangi. The analysis method used is observation, and the data obtained are analyzed using descriptive statistics. The research was conducted as a case study, using both primary and secondary data. The incubated eggs used had a weight of 41-55 grams and were obtained from UPTD BPPTU Jatiwangi with a male-to-female ratio of 1:5. The observed parameters were fertility, hatchability, and salable chicks. The research results showed an average fertility of 81.62±1.34% with a coefficient of variation of 1.64%, hatchability of 74.64±4.94% with a coefficient of variation of 6.61%, and salable chicks of 96.4±1.65% with a coefficient of variation of 1.71%.
