Abstract

This study aimed to analyze the relationship between quantitative traits and reproduction traits of Ongole grade cows in Rembang Regency. This study was done from May to July 2022. The number of samples used was 224 Ongole grade cows that have given birth at least once. Quantitative traits were obtained by measuring body condition scores (BCS), body length (BL), body height (BH) and chest circumference (CC). The class was based on Indonesian National Standards for Ongole grade cow breeding cattle in 2015 (Class I, II, III and Non-Class). The BCS used is the American system for beef cattle (score 1 to 9). The BL and BH were measured with a measurement stick. The CC was measured using the weight body Round-O (WB Round-O). The reproductive traits measured included service per conception (S/C), calving interval (CI), days open (DO) and estrus postpartum (EPP), which were obtained by observing cattle and interviewing breeders and inseminators. The analysis used was descriptive statistical analysis with averages and percentages and non-parametric analysis of Spearman’s correlation test.  This research concludes a significant relationship between quantitative traits and S/C with a very weak negative direction and strength of the relationship.

Abstract

This study aimed to evaluate the growth performance of Red-Combed Kedu (RCK), Black-Combed Kedu (BCK), and White Kedu (WK) chickens based on sex during the early growth phase (0 to 10 weeks of age). A total of 136 Kedu chickens were raised under uniform management conditions, consisting of 99 RCK (65 roosters and 34 hens), 29 BCK (5 roosters and 24 hens), and 8 WK (6 roosters and two hens). Body weight was recorded weekly and analysed using a two-way General Linear Model (GLM) in SAS to assess the effects of chicken variety, sex, and their interaction. The Shapiro–Wilk test confirmed that the data were normally distributed (p > 0.05). The results showed that sex had a significant effect on body weight from weeks 3 to 10 (p < 0.05), with roosters consistently exhibiting higher weights than hens. Significant differences among chicken varieties were observed only in the hen group at weeks 9 and 10, where BCK hens had higher body weights (p < 0.05) than WK hens, while RCK hens showed intermediate values. In contrast, no significant differences were found among rooster groups at any age. These findings suggest that genetic factors play an essential role in influencing growth performance in Kedu chickens, particularly in hens. This information provides a valuable foundation for breeding selection and the conservation of local chicken genetic resources.

Abstract

This study aims to describe the Libyan chicken breed and its origin, and to evaluate its potential for the development of a new Libyan local chicken breed with high genetic quality and productivity. A qualitative research design has been implemented to carry out this research with a descriptive-analytical approach. Data collection was done by reviewing scholarly literature from scientific journals, academic books, and credible online databases. This research analyzed previous studies to determine patterns that outline the genetic potentials, challenges, and opportunities in breeding programs for enhancing the productivity and resilience of Libyan local chickens. The results showed that the indigenous chicken varieties of Libya, such as Gallus gallus, Baladi or El-Balad, and Hypeco, are essential to the nation's agricultural and culinary traditions. These varieties are hardy and ideal for rural and semi-urban locations with limited access to contemporary farming infrastructure. This study's findings highlight Hypeco's potential as a top contender for the creation of a new breed of locally grown chickens in Libya with superior genetic quality and productivity. In the face of issues with food security, their resilience to intense heat, limited feed supply, and limited water supplies makes them priceless assets. A lack of effective farming methods, contemporary breeding procedures, and the required infrastructure limits these local hens' production and economic viability. These local hens' production and economic viability are limited by a lack of effective farming methods, contemporary breeding procedures, and the required infrastructure. Building infrastructure to assist the regional poultry business should also be a priority. This entails expanding access to veterinary care, storage facilities, water, and high-quality feed.
