“…Many experiments have confirmed that both production and reproductive traits depend on genetic factors (King'ori, 2011;Miazi et al, 2012). In birds, egglaying is the consequence of a complex cascade of progressive maturational events involving the entire hypothalamic-pituitary-gonadal axis.…”

Abstract:The laying quail is a worldwide breed which exhibits high economic value. In our current study, the vasoactive intestinal peptide receptor-1 (VIPR-1) was selected as the candidate gene for identifying traits of egg production. A single nucleotide polymorphism (SNP) detection was performed in 443 individual quails, including 196 quails from the H line, 202 quails from the L line, and 45 wild quails. The SNPs were genotyped using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Two mutations (G373T, A313G) were detected in all the tested quail populations. The associated analysis showed that the SNP genotypes of the VIPR-1 gene were significantly linked with the egg weight of G373T and A313G in 398 quails. The quails with the genotype GG always exhibited the largest egg weight for the two mutations in the H and L lines. Linkage disequilibrium (LD) analysis indicated that G373T and A313G loci showed the weakest LD. Seven main diplotypes from the four main reconstructed haplotypes were observed, indicating a significant association of diplotypes with egg weight. Quails with the h1h2 (GGGT) diplotype always exhibited the smallest egg weight and largest egg number at 20 weeks of age. The overall results suggest that the alterations in quails may be linked with potential major loci or genes affecting reproductive traits.

“…This opinion is supported by the Sidadolog (2011) which states that every individual has the arrangement of genes (2n) in accordance with genes obtained from the parents. Applegate et al (1998) and King'ori (2011) add that hatchability is a quantitative trait that can be measured in chicken. Quantitative trait is influenced by a large number of gene pairs, each of which can act additive, dominant or epistasis (Noor, 2008), together with environmental influences/nongenetik (Martojo, 1992;Dzoma, 2010).…”

Abstract. This study was conducted to determine the reproductive performance of various breeds of Sentul chicken. The present research was assigned in an experiment model with a completely randomized design (CRD), with 5 breeds of Sentul chicken as treatments, namely Abu Sentul chicken = SA; Batu Sentul Chicken=SB; Emas Sentul Chicken=SE; Debu Sentul Chicken=SD; and Geni Sentul Chicken=SG. Each treatment was repeated 5 times with 4 female and 1 male birds each, thus the total number of chicken were 100 females and 25 males with an average initial female weight was 1,336.05±84.99 g and male weight was 2,050.53±121.78 g. The experiment was conducted for 14 weeks started from 20 week old until 34 week old. Variables measured were spermatozoa production, fertility, and hatchability. Data were subjected to analysis of variance and HSD test. Results showed that various breeds of Sentul chicken had no significant effect (P>0.05) on spermatozoa production, and had significant effect (P<0.05) on fertility and hatchability. It can be concluded that spermatozoa production of various breeds of Sentul chicken are relatively similar, while fertility and hatchability of Emas chicken was lower than that of Abu Sentul chicken and Batu Sentul Chicken. Key words:Reproductive performance, spermatozoa production, fertility, hatchability, Sentul chicken Abstrak. Penelitian ini dilakukan untuk mengkaji kinerja reproduksi berbagai jenis ayam Sentul. Penelitian ini menggunakan metode eksperimen dengan rancangan acak lengkap (RAL), Perlakuan adalah 5 jenis ayam Sentul yang terdiri atas ayam Sentul Abu = SA; ayam Sentul Batu = SB; ayam Sentul Emas = SE; ayam Sentul Debu = SD; dan ayam Sentul Geni = SG. Setiap perlakuan diulang 5 kali masing-masing terdiri dengan 4 betina dan 1 ekor jantan, sehingga jumlah total ayam sentul ada 100 ekor betina dan 25 ekor jantan dengan berat awal rata-rata ayam betina adalah 1.336,05±84,99 g dan berat ayam jantansebesar 2.050,53±121,78 g. Penelitian dilakukan selama 14 minggu mulai dari umur 20 minggu sampai 34 minggu. Variabel yang diukur adalah produksi spermatozoa, fertilitas, dan daya tetas. Data yang diperoleh kemudiandianalisis variasi dan dilanjutkan uji BNJ. Hasil penelitian menunjukkan bahwa berbagai jenis ayam Sentul tidak berpengaruh (P>0,05) terhadap produksi spermatozoa, dan berpengaruh nyata (P<0,05) pada fertilitas dan daya tetas. Penelitian ini dapat disimpulkan bahwa produksi spermatozoa berbagai jenis ayam Sentul relatif sama, sedangkan fertilitas dan daya tetas ayam Sentul Emas lebih rendah dibandingkan ayam Sentul Abu dan ayam Sentul Batu.

“…This implies that their contribution to the household protein food security may not be fully realized without appropriate management and husbandry interventions as suggested by many workers (Abiola 1999;Donald et al 2002;Rashid et al 2005;King'ori et al 2007), who reported that performance in chickens in terms of hatchability and chick hatch-weight may be closely related to the weight of the eggs because the main effect of egg size lies in the mass of the residual yolk sac that the chick retains at hatching. King'ori (2011) suggested that chick weight, fertility and hatchability are interrelated heritable traits that vary among breeds, variety or individuals in a breed; it therefore becomes very important to understand the effect of egg size on these traits in Habbard broiler chickens. Egg size has been widely studied in the context of the bird's life-history theory because it can be highly variable.…”

A total of 2000 Hubbard Classic females and 180 males (male to female ratio 1:11) close to standard body weights were selected and managed separately in the same shed. The objective of this experiment was to study the effects of egg size (small, medium and large) at mid (45 weeks) production cycle and flock age (30, 45 and 60 weeks old) on hatching egg weight loss, fertility, hatchability traits, chick weight and chick yield in a commercial Hubbard Classic broiler breeder flock. The results showed that minimum egg weight loss (P ≤ 0.05) was recorded in large egg size group at different incubation periods and egg weight losses decreased with advancing the age of breeder hens. Maximum fertility and hatchability (P ≤ 0.05) was noticed in small egg size group, followed by medium and large egg size groups. However, maximum embryonic mortality (P ≤ 0.05) during incubation and higher percentage of infertile eggs was recorded in large size egg group, followed by medium and small egg size groups. Low fertility, hatchability was recorded (P ≤ 0.05) in older hen at the age of 60 weeks. The chick weight and chick length were amplified (P ≤ 0.05) with increasing the egg size. However, egg size was not influenced (P ≥ 0.05) on chick yield. The chick weight, chick yield and chick length were improved (P ≤ 0.05) with advancing age of broiler breeder.
