Abstract

This research aimed to compare the productivity of GPS strains, namely Ross, Cobb, Hubbard, and Indian River in hens and males at 21 weeks of age. The research data was obtained from the results of an audit of the breeding company by the Directorate General of Livestock and Animal Health, Ministry of Agriculture, from November 2022 to March 2023. The results showed that the comparison of hen productivity in the four strains, namely (1) the Indian River strain had a high body weight compared to other strains, (2) the Hubbard strain has a higher depletion rate than the other strains, but this depletion rate does not reflect bad or bad genetics, but it reflects a high degree of selection, and (3) the Indian River strain has a higher uniformity level than other strains. The productivity of roosters is (1) the Indian River strain has a high body weight compared to other strains, (2) the Indian River strain has a higher depletion rate than the other strains, however, this depletion rate does not reflect bad or bad genetics, but it reflects high selection rate, and (3) Indian River strain has a higher uniformity level than other strains.

Abstract

The production performance of GPS on Cobb, Indian River, and Hubbard strains has not been well studied. This study aimed to compare the production performance between female GPS strains at 24 weeks of age and the standards set by each principal. This research was conducted from November 2022 to March 2023. The results showed a significant difference in most production performance between GPS strains at 24 weeks of age by each strain. Significant differences were observed for body weight, feed consumption, depletion and uniformity. As for comparing the production performance between the GPS strains and the standards set by the principal, there were also significant differences, and several performance parameters exceeded the standards. This result was influenced by different farming management patterns from each company adapting to actual conditions in the field.

Abstract

This study aims to compare the performance of broiler GPS flocks from 4 GPS strains in Indonesia (Cobb, Ross, Indian River, Hubbard). This research was conducted from November 2022 to March 2023. Data were collected from some breeding companies' audit results conducted by the Directorate General of Livestock and Animal Health. The results showed that the broiler GPS flock performance in the young age group showed a significance value of <0.05, and there was a significant difference in the HDP variable indicator. The average HDP weight for the Ross, Cobb, Indian River, and Hubbard GPS strains was 78.05±3.28, 74.00±3.30, 78.99±3.37 and 75.85±3.61, respectively. The average egg and hatchling weight was also significantly different among each strain, but only on the variable factor of the breeding company. There were no significant differences among the strain factor variables and primary product variables, such as the average number of DOC PS per hen by breeding company and strain. On average, a female GPS line in the young age group period for the Ross, Cobb, Indian River, and Hubbard strains produced 15.14 ± 2.2, 14.92 ± 4.6, 15.35 ±1.47, and 13.78 DOC, respectively. There is no mutual interaction between the performance of HDP flocks, egg weight, and hatching weight of DOC PS from variable factors of the breeding companies with each strain. Factorial interactions only occur in the primary product variable, meaning each broiler GPS strain reared by each breeder company in Indonesia has different performances.

Abstract

Production performance research was carried out on three Grand Parent Stock (GPS) broiler strains, namely Indian River, Ross and Cobb. The data was obtained from the results of production performance audits of broiler GPS breeders during the laying period of 25 – 65 weeks. Variables measured include laying lifeability, egg/hen house production, rate peak production/hen house, hatching egg/hen house production, fertility, hatchibilty, and saleable chick/henhouse. Data were analyzed quantitatively using t-test, analysis of variance (Anova) and Duncan. This study showed that the Indian river strain had higher production characteristics in terms of vitality, egg production, peak production, hatching egg production, and saleable chicks. Ross strains have higher production characteristics at rates of peak production, fertility, hatchability, and saleable chicks. The cobb strain has the lowest production performance compared to the other strains. Comparison between the strains and the principle standard shows that the actual hatchability and saleable chicks were lower than the standard in the Indian Rivers strain. The Ross strain had an actual value greater than the standard for fertility, hatchability and saleable chicks. Whereas the actual values for the Cobb strain for viability, egg production, peak production, hatching egg production, and saleable chicks were lower than the standard.
