“…The heritability estimates for the traits in the present study were medium to high (ranging from 0.269 to 0.642; see Table 2), similar to the results of studies carried out in local Venda chickens [25], Mazandaran native chickens [22], and Thai native chickens [18,19,21]. This demonstrated that genetics influenced these traits, which are sufficient for genetic evaluation with acceptable accuracy.…”

“…The mean body weights of KM2 among generations demonstrated that the selection method used in our study was effective, as the body weights increased over the generations (Figure 2b). Compared with previous reports on TNC and TSC breeds, all ages had a higher mean than TSC [17], TNC [18,19], the India crossbred chicken [11], and the Horro chicken of Ethiopia [20]. Selection for rapid early growth to market weight (1.2 kg) is the most common method of selection in native chickens.…”

To improve the genetics of both growth and egg production, which are limitations in purebred native chickens, new genetic lines can be developed using an appropriate genetic approach. The data used in this study included 2713 body weight (BW0, BW4, BW6, BW8, and BW10), breast circumference (BrC6), chicken age at first egg (AFE), and egg production (240EP, 270EP, 300EP, and 365EP) records covering the period 2015 to 2020. A multi-trait animal model with the average information-restricted maximum likelihood (AI-REML) and a selection index was used to estimate the variance components, genetic parameters, and breeding values. The results showed that males had significantly higher weights than females (p < 0.05) from 4 to 10 weeks of age and that this difference increased over the generations. The differences between BW0 and BrC6 by sex and generation were not significant (p > 0.05). The estimated heritability of body weight ranged from 0.642 (BW0) to 0.280 (BW10); meanwhile, the estimated heritability of BrC6 was moderate (0.284). For egg production traits, the estimated heritability of 240EP, 270EP, 300EP, and 365EP was 0.427, 0.403, 0.404, and 0.426, respectively, while the estimated heritability of AFE was 0.269. The genetic and phenotypic correlations among the growth traits (BW0 to BW10) were low to highly positive. The genetic and phenotypic correlations between growth (BW0 to BW10) and BrC6 traits were positive, and the genetic correlations between BW6 (0.80), BW8 (0.84), BW10 (0.93), and BrC6 were strongly positive. Genetic correlations among the egg production traits (240EP, 270EP, 300EP, and 365EP) were low to highly positive and ranged from 0.04 to 0.86. The genetic correlations between AFE and all egg production traits were low to moderately negative and ranged from −0.14 to −0.29. The positive genetic correlations between body weight (BW6, BW8, and BW10) and egg production traits were found only in 240EP. The average genetic progress of body weight traits ranged from −0.38 to 30.12 g per generation for BW0 to BW10 (p < 0.05); the genetic progress was 0.28 cm per generation for BrC6 (p > 0.05). The average genetic progress of cumulative egg production traits ranged from 4.25 to 12.42 eggs per generation for 240EP to 365EP (p < 0.05), while the average genetic progress of AFE was −7.12 days per generation (p < 0.05). In conclusion, our study suggests that the body weight at six weeks of age (BW6), breast circumference at six weeks of age (BrC6), cumulative egg production at 240 days of age (240EP), and age at first egg (AFE) are the traits that should be used as selection criteria, as they have a positive effect on the development of growth and egg production.

“…Early growth performance traits, such as birth weight (BW) and weaning weight (WW), are the basis for selection in genetic improvement programs for meat production ( 1 ). To investigate the relationships between body weight and meat quality traits, PCR-restriction fragment length polymorphism and PCR-single strand conformation polymorphism were applied to suggest a low negative relationship between BW, meat quality, and genetic markers ( IGF-II and CAPN1 ) in chickens breeding for meat quality ( 2 ). However, conventional breeding methods cannot make significant progress in a short period of time.…”

Objective: Body weight is an important economic trait for a goat, which greatly affects animal growth and survival. The purpose of this study was to identify genes associated with birth weight (BW), weaning weight (WW), and yearling weight (YW).Materials and Methods: In this study, a genome-wide association study (GWAS) of BW, WW, and YW was determined using the GGP_Goat_70K single-nucleotide polymorphism (SNP) chip in 1,920 Inner Mongolia cashmere goats.Results: We discovered that 21 SNPs were significantly associated with BW on the genome-wide levels. These SNPs were located in 10 genes, e.g., Mitogen-Activated Protein Kinase 3 (MAPK3), LIM domain binding 2 (LDB2), and low-density lipoprotein receptor-related protein 1B (LRP1B), which may be related to muscle growth and development in Inner Mongolia Cashmere goats. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that these genes were significantly enriched in the regulation of actin cytoskeleton and phospholipase D signaling pathway etc.Conclusion: In summary, this study will improve the marker-assisted breeding of Inner Mongolia cashmere goats and the molecular mechanisms of important economic traits.

“…The significantly prominent birth weight (29.58 g) was found in the FC group (p<0.05), followed by FAH (28.13 g), CF (27.09 g) and CHE (26.78 g), respectively. These results corresponded to Thai native black-bone chickens, namely Chee Fah (Morathop et al, 2005) and Fah Luang (Intarachote et al, 2003;Intharachote et al, 2005), and other Thai indigenous chickens (Penmas, 2005;Leotaragul et al, 2015;Sungkhapreecha et al, 2015;Molee et al, 2018). While, some studies revealed higher birth weights (Suayroop et al, 2012;Siripanya et al, 2013;Patra et al, 2018), which might be due to they were genetically improved for productive performance.…”

This study was conducted to compare productive performance between purebred Thai indigenous black-bone chickens and their reciprocal crossbreds. Four different genetic groups were studied: 2 purebreds (Chee Fah and Fah Luang) and 2 crossbreds (Chee Fah ´ Fah Luang and Fah Luang ´ Chee Fah). The results showed that Fah Luang ´ Chee Fah had the significantly highest body weight at birth and 20-week of age, while the lowest values were found in Chee Fah ´ Fah Luang (p less than 0.05). For feed conversion ratio, Fah Luang ´ Chee Fah had greater potential than purebreds and Chee Fah ´ Fah Luang (p less than 0.05). Additionally, Fah Luang ´ Chee Fah grew faster than the others (p less than 0.05). The productive performance of crossbred chickens was more favorable than purebreds. Considering crossbreds, Fah Luang ´ Chee Fah showed greater performance than Chee Fah ´ Fah Luang. Therefore, Fah Luang had more potential for using as a sire than Chee Fah.
