“…The fertility rates of Kamrupa chickens reared under a backyard system in Assam were determined to be 91.10±2.30%. These findings align with the research conducted by Saikia et al (2017) [13] , who reported similar results in Vanaraja and Indigenous chickens of Assam. Examining hatchability percentages, Kamrupa recorded 83.62%, on a total egg set basis, and 86.48% on a fertile egg set basis.…”

“…Examining hatchability percentages, Kamrupa recorded 83.62%, on a total egg set basis, and 86.48% on a fertile egg set basis. Saikia et al (2017) [13] also reported higher percentages of hatchability on a total egg set basis (88.52±3.95% and 86.14±3.26%) in indigenous and Vanaraja chickens of Assam, aligning closely with the present study. In contrast, Kumer et al (2005) [8] reported a lower hatchability rate of 72.6% in Vanaraja birds under a traditional rearing system.…”

Kamrupa, a dual-type, high-yielding chicken breed developed through the efforts of the AICRP on Poultry Breeding at AAU, Khanapara, has been successfully introduced across various regions of the North East. However, comprehensive studies regarding the productive and reproductive performance of Kamrupa chickens under the backyard rearing system in Assam are exceedingly limited. With this gap in mind, the current research aims to evaluate the economic characteristics of Kamrupa chickens within the context of the backyard rearing system in Assam.The study encompassed a range of parameters, including body weights at various stages (day old, 5, 20, 40, 52, and 72 weeks), age at initial egg laying, egg production up to 40, 52, and 72 weeks, egg weights at 32, 40, 52, and 72 weeks, age at sexual maturity, carcass attributes, egg quality traits, fertility, and hatchability. Analysis of the data revealed that the average body weights for Kamrupa chickens were as follows: 36.59±2.45 (day old), 218.25±28.95 (5 weeks), 1045.19±31.02 (20 weeks), 1721.56±41.57 (40 weeks), 1756.57±43.31 (52 weeks), and 2045.65±59.26 (72 weeks). Egg production data highlighted that Kamrupa chickens yielded 42. 34±2.96, 83.56±5.96, and 143.45±8.69 eggs up to 40, 52, and 72 weeks, respectively. In conclusion, the study implies that Kamrupa chickens exhibit superior performance in terms of body weight, egg production, and various other traits when reared under the backyard system in Assam.

“…Islam et al[7] and Sarma et al[9] also recorded the similar findings in Vanaraja and indigenous chicken of Assam under backyard system. The present findings were also comparable with the findings of Zuyie et al[12], Deka et al[11] and Saikia et al[8] for Vanaraja birds. In contrast to the findings, Pathak and Nath[13] recorded much lower values for Vanaraja and Desi chicken in Sikkim.…”

“…Islam et al [7] also reported a comparable body weights at 8 and 20 weeks of age in case of Vanaraja and indigenous chicken in Assam. Significantly higher body weights of Vanaraja birds at different ages were also observed by Saikia et al [8]. Sarma et al [9] reported that the average body weights in Vanaraja birds were significantly (P<0.05) higher followed by Kamrupa and Desi in similar ages.…”

Productive and reproductive performances in terms of body weight, age at first egg, egg production, egg weight, fertility, hatchability and mortality of Vanaraja, Rainbow Rooster, Kamruapa and Desi chicken of Assam were studied under traditional backyard system of rearing. The Vanaraja, Rainbow Rooster and Kamruapa birds were given to rear under the frontline demonstration programmes of the Krishi Vigyan Kendra, Dhemaji to the women farmers of the district during 2020-21. The data on bird weights at different ages, egg weights, fertility, hatchability as well as mortality were collected and recorded and compared among the varieties. The data recorded from the study were analyzed as per standard statistical methods. The overall mean body weights were significantly (P < 0.05) higher in all the improved varieties than Desi chicken at different ages. There is also significant (P < 0.05) difference of age at first egg among Vanaraja (182.05±5.52 days), Rainbow Rooster (175.08±6.13 days), Kamruapa (163.06±5.52 days) and Desi chicken (203.31±3.31 days). The mean egg production values up to 32, 40, 52 and 72 weeks of age in the demonstrated varieties were significantly (P < 0.05) higher than the corresponding values of Desi birds. The mean egg weights of Vanaraja, Rainbow Rooster, Kamruapa at 32, 40 and 52 weeks of age were also significantly (P < 0.05) higher than Desi birds. However, no significant difference was observed in mortality rates among the four groups at different ages. There was also no significant (P < 0.05) difference in fertility and hatchability percent among the four genetic groups. It is concluded that Vanaraja, Rainbow Rooster and Kamruapa birds are adapted well under traditional backyard rearing system in agro-climatic conditions of Dhemaji district of Assam with adequate economic advantages over the Indigenous birds.

“…Deka et al, (2014) also recorded lower mean age at first egg in Vanaraja (178.13±0.79 days) and indigenous chicken (191.25±1.46 days) under backyard system. Besides, Bharali et al, (2020), Kumar et al, (2018), Sree et al, (2017) and Saikia et al, (2017) Means bearing similar superscripts in a row do not differ significantly.…”
