Assessment of egg quality and biochemical parameters of Aseel and Kadaknath indigenous chicken breeds of India under backyard poultry farming

Abstract

Egg quality parameters are very crucial for the egg industry as egg configuration affects grading, price, hatchability, chick weight, and consumer preference. Current study was undertaken to assess and compare the egg quality parameters in 2 important Indian breeds Aseel and Kadaknath reared under backyard system. Different parameters of external and internal egg quality were measured. Biochemical parameters of egg yolk estimated were egg yolk cholesterol, high density lipoprotein ( HDL ), low density lipoprotein ( LDL ), and triacylglycerol. Means for external characters of Aseel eggs viz., egg weight, egg length, egg width, shape index, shell weight, shell thickness, and shell ratio were 41.7 g, 5.16 cm, 3.85 cm, 74.75%, 4.65 g, 0.35 mm, and 11.23%, and corresponding values for Kadaknath eggs were 40.59 g, 5.13 cm, 3.79 cm, 74.02%, 4.28 g, 0.34 mm, and 10.61%, respectively. Average albumin length, width, height, and albumin index were 83.73 mm, 65.4 mm, 6.02 mm, and 9.26% for Aseel eggs and 82.27 mm, 64.80 mm, 5.52 mm and 8.52% for Kadaknath eggs, respectively. Mean values for yolk length, width, height and yolk index were 43.32 mm, 40.10 mm, 15.30 mm, and 38.30% in Aseel and 42.15 mm, 38.97 mm, 14.26 mm and 36.66% in Kadaknath breed, respectively. Mean values for egg yolk cholesterol, HDL, LDL, and triacylglycerol were estimated as 9.38, 1.74, 0.17, and 1.94 mg/g in Aseel eggs and 8.38, 1.84, 0.11, and 1.76 mg/g in Kadaknath eggs, respectively. Biochemical analysis revealed that egg yolk quality of Kadaknath eggs was comparatively better than Aseel eggs.

Biological evaluation of developed supplement feed (DSF) for egg quality parameters in LIT (Himsamridhi) birds

“…Variation in egg weight is also strain specific with many of the authors reporting lower egg weight in mid laying phase. Kumar et al (2022) [23] demonstrated lower egg weight of 41.70±0.55 g and 40.59±0.55 g in LIT birds namely Aseel and Kadaknath chicken at mid laying phase respectively. The egg Shape Index (SI) is the ratio of the short diameter of the egg to the long diameter and is graded as sharp (<72), normal (72-76) and round (>76).…”

Physical Quality Parameters and Activity of Albumen Lysozyme of Eggs From Traditional Hens Bred in Poland Compared With Commercial Hybrids

“…However, differences in shape were found depending on the genotype, with similar values obtained for PLB and HLB eggs. Also, a previous study showed the influence of genotype and age, and the interaction of these two factors (Tůmová et al, 2007;Ledvinka et al, 2011;Lordelo et al, 2020;Kumar et al, 2022) on the egg shape index. Rizzi et al (2022) showed that for eggs of Italian hen breeds, the values of this parameter ranged from 73.2 (Ermellinata di Rovigo) to 77.9% (Padovana Camosciata, chamois plumage).…”

“…Particularly noteworthy are Polish Liliputy Bantams eggs, characterized by the low weight and a high proportion of more intensely colored yolk and good Haugh unit score at the end of production period. Key words: genotype, egg, physicochemical parameters, lysozyme In recent years, there has been an increasing interest in the quality of products from local breeds and varieties of hens (Franco et al, 2020;Lordelo et al, 2020;Marelli et al, 2020;González Ariza et al, 2022) especially those kept in non-intensive production systems like freerange and organic systems (Sirri et al, 2018;Kumar et al, 2022;Rizzi et al, 2022). The variation in egg quality characteristics from these hens may be attractive to consumers.…”

Indian Chicken Breeds

“…The plumage of these birds is black, the shanks are feathered, the skin is white, and the comb is single. Kumar et al [42]. report an annual egg production of about 137 eggs.…”
