“…This can be due to environmental effects which may have contributed to selection for this genotypes in different population. In No significant difference was found in this study between the body weight and the genotypes which is contrary to the findings of Sinpru et al [19], where a significant difference between body weight and genotype was reported. Polymorphisms of GH gene have been reported in chickens at intron1, 3 and 4.…”

The candidate gene approach is a valuable tool for improving breeding programs, particularly in poultry, by identifying traits for enhanced production performance. This study investigates the growth hormone (GH) gene as a potential determinant of body weight in Nigerian indigenous turkeys. DNA was extracted from 60 twelve-week-old turkeys using blood samples, and a 466bp DNA fragment was amplified via PCR with primers designed from chicken sequences. The PCR product underwent Msp1 restriction enzyme digestion and was visualized on a 1.5% agarose gel. Genotypes associated with body weight were assessed using a General Linear Model. The GH/Msp1 locus revealed Two alleles (A and G) and three genotypes (AA, AG, and GG), with allele G being predominant. Genotype AG had the highest frequency (0.55), followed by AA (0.42), and GG had the lowest frequency (0.03). However, the least square means analysis showed that the polymorphism in the GH gene of the studied population was not significantly associated with body weight (p> 0.05). Nonetheless, the polymorphic nature of the GH gene in Nigerian turkeys suggests potential for further exploration in quantitative traits.

“…Harvey dan Daughaday (1995), menyatakan bahwa hormon pertumbuhan yang disekresikan oleh pituitari anterior dan tiroksin yang disekresikan oleh kelenjar tiroid bekerja secara simultan dalam mengontrol pertumbuhan unggas menjelang pubertas. Oleh karena itu perbedaan antara hormon jantan dan betina merupakan salah satu faktor yang sangat menentukan mengapa pertumbuhan jantan lebih besar daripada pertumbuhan ayam betina (Sinpru et al,2021).…”

This study aims to identify the quantitative and qualitative performance of native chickens in The Mother breeding farm. This study used 50 male native chickens and 50 female native chickens aged 7 months. Variables observed included body hair pattern color, comb shape, comb color, shank color, eye color, beak color, body weight, chest circumference, shank length, shank circumference, body length, pubic bone length to chest, pubic bone distance and length wing span. Data were analyzed using descriptive analysis. The results of this study indicate that the body color of the male is Columbian (100%), while the female is solid black (62%), columbian (22%) and speckled or dotted (16%). The male cockscomb is pea (86%) and single (14%), while the female is pea (70%), walnut (20%) and single (10%). The color of the male comb is red (100%), while the female is red (98%) and black (2%). The shank color of males is yellow (74%), black (14%) and white (12%), females are black (74%), white (16%) and yellow (10%). Male eye color is orange (76%) and yellow (24%), while females are orange (66%), yellow (20%) and brown (14%). The color of the male's beak is yellow (54%), black and yellow (38%) and white (8%), while the female's beak is black and yellow (82%), yellow (10%) and white (8%). The results of the quantitative characteristics of the study showed that the male body weight was 2.22 ± 2.02 kg and the female was 1.71 ± 0.25 kg, the male chest circumference was 33.9 ± 3.68 cm and the female was 30.67 ± 2.08 cm, the length male shank 9.61 ± 0.89 cm and female 27 ± 0.59 cm, male shank circumference 5.52 ± 0.65 cm and female 4.4 ± 0.5 cm, male body length 20.27 ± 1.17 cm and female 20.40 ± 2.27 cm, the length of the pubic bone to the chest of the female is 7.87 ± 1.06 cm, the distance between the pubic bones is 2.8 ± 0.49 cm, the length of the male wing span is 23.28 ±2.18 cm and females 16.61±2.44 cm. The conclusion of this study is that the quantitative and qualitative characteristics of free-range chickens on The Mother farm are diverse and selection can be made.

“…In addition, BW gain, feed intake, and feed conversion showed a significant increasing trend compared with the first week. Growth hormone and IGF2 genes are candidate genes for growth performance in chickens [24][25][26]. Therefore, these genes are usually considered candidate genes in the genetic analysis of complex animal traits such as growth rate, body composition, and fat deposition [27].…”

Background and Aim: Poultry, such as chickens, is an important source of animal protein, producing eggs and meat. Local chickens are able to adapt to the hot weather and become more resistant to disease. However, it has relatively slow growth and low egg production. These problems can be overcome through holding selection and crossing. Local chicken productivity is slow and low based on chicken growth. There is a need to examine the factors that influence growth and productivity. Therefore, this study aimed to evaluate crossbreed chicken growth performance, including body weight (BW), BW gain, feed intake, and feed conversion. Materials and Methods: DNA was extracted from 40 chickens with the growth hormone (GH) gene and 40 chickens with the insulin-like growth factor 2 (IGF2) gene, followed by a polymerase chain reaction. Genotyping was performed using restriction fragment length polymorphism analysis. In animal selection and phenotypic data collection, 80 chickens from Sentul, Kampung, and Kedu were used to produce the second-generation three-crossbreed chickens (F2) using the GH gene. Results: Growth hormone is a very relevant gene in chicken performance traits. Growth hormone and IGF2 genes regulate chicken production. This study presents the second-generation growth features of three-crossbreed chickens derived from Sentul, Kampung, and Kedu, all of which are native to Indonesia (F2). A statistically significant (p = 0.05) improvement in BW, weight gain, feed intake, and feed conversion over a 12-week period was observed when the animals were allowed free access to regular feed. Analysis of variance results indicated a significant (p = 0.0001) interaction between the 12-week period and GH and IGF2 gene sensitivities of different chicken breeds. Conclusion: Crossbreed chicken growth performance increased within 12 weeks. This study highlighted the need to improve the productivity and breeding of domestic crossbred chickens to contribute to the Indonesian conservation and genetic diversity program. Keywords: body weight, domestic chicken crossbreed, feed conversion, growth hormone gene, insulin-like growth factor 2 gene.
