Comparative studies on egg, meat, and semen qualities of native and improved chicken varieties developed for backyard poultry production

Abstract

The objective of the present study was to evaluate/compare the sensory attributes of eggs and meat, egg qualities, proximate composition of eggs, and semen qualities of slow growing native (Miri and Mizo-local) and fast growing improved chicken varieties (Gramapriya and Vanaraja) under hill ecosystem of northeastern India. Significantly higher egg weight, egg volume, and albumen volume were observed in Gramapriya followed by Vanaraja, Mizo-local, and Miri chickens. However, yolk volume was significantly higher in Vanaraja and Gramapriya varieties as compared to native chickens. Yolk to albumen ratio was significantly lower in Gramapriya as compared to Vanaraja and Miri chicken. Consumer liking of eggs for aroma, flavor, and overall acceptability of Miri, Mizo-local, and Vanaraja were significantly higher than that of Gramapriya. Genetic groups did not differ significantly in appearance and proximate composition of eggs. No significant differences were observed between various genetic groups for sensory attributes of meat samples. Semen volume was significantly (p < or = 0.01) lower while sperm concentration was significantly (p < or = 0.01) higher in native chicken as compared to the improved chicken varieties. However, pH, mass activity, sperm motility, and livability did not differ significantly among genetic groups although Mizo-local had significantly higher abnormal sperm count. The study concluded that the genetic groups with different growth rate differed significantly for various egg quality parameters and semen characteristics but not for sensory attributes of meat and proximate composition of eggs.

Productive Performance and Egg and Meat Quality of Two Indigenous Poultry Breeds in Vietnam, Ho and Dong Tao, Fed on Commercial Feed

“…However, the earliest slaughtering time in our experiment (12 weeks) led to average values of 23.16N and 23.64N for Ho, and Dong Tao, respectively, which is definitely much higher than these commercial standards. Genetic differences between breeds and the slaughter age can affect the tenderness of chicken meat [27,28]. Our study supports these hypotheses, showing differences between breeds, and a decrease of the tenderness with the age at slaughter.…”

Comparative study on immunoglobulin Y transfer from breeding hens to egg yolk and progeny chicks in different breeds of poultry

“…This is also in conformity with reports of Haunshi et al . [ 25 ]. Similar to present finding, Li et al .…”

Characterization of two Indian native chicken breeds for production, egg and semen quality, and welfare traits

“…Despite having a higher BW, the Aseel breed showed no significant difference from the Kadaknath breed in the volume of ejaculate; however, a slightly higher average volume of ejaculate was observed in the Kadaknath breed. This finding was somewhat unexpected because it has been established that cockerels with a higher BW will have a greater volume of ejaculate compared with their counterparts with a lower BW (Haunshi et al, 2010). However, Biswas et al (2009) reported a lower volume of ejaculate for the Kadaknath breed at about 30 wk of age.…”
