“…The analysed complement genes, inflammatory cytokines, mucin and crp all show different expression patterns than have been previously reported in β‐glucan fed carp (Falco et al ., ; Pionnier et al ., , ; van der Marel et al ., ). It has also been shown that different breeding lines of fish species, including carp, have significantly different immune responses under disease free conditions as well as against bacterial and viral pathogens (Adamek et al ., ; Kobis et al ., ; Marancik et al ., ; Nath et al ., ). It is possible that the use of different lines of carp is responsible for the differing expression patterns noted between studies.…”

β-glucans are frequently included in the diet of healthy common carp Cyprinus carpio as a pre-emptive measure for combatting disease. In order to study the effect this has on the relationship between the gut bacteria and host immune response, carp were maintained on either a β-glucan free diet or feed containing 0.1% MacroGard ® , a β-1/3, 1/6-glucan, for up to 7 weeks and analysis of innate immune gene expression and molecular analysis of the gut bacteria was performed. The data reveals feeding of MacroGard ® to healthy carp does not induce bactericidal innate immune gene expression in the gut but does appear to alter bacterial species richness that did not have a negative effect on overall health. Analysis of innate immune gene expression within the upper midgut revealed that there were significant changes over time in the expression of Interleukin (il)-1β, inducible nitric oxide synthase (inos), mucin (muc2) and C-reactive protein (crp2). Diet did not affect the number of copies of the bacterial 16s rDNA gene in the gut, used as a as a measure of total bacteria population size. However, PCR-denaturing gradient gel electrophoresis (DGGE) analysis revealed a shift in bacterial species richness with MacroGard feeding. Bactericidal immune gene expression of crp2, muc2 and il-1β was weakly correlated with gut bacteria population size indicating a potentially limited role of these genes in interacting with the gut bacteria in healthy carp in order to maintain gut homeostatic conditions. These findings highlight the importance of considering both host immunity and the microbiome together in order to fully elucidate the effeect of immunomodulants, such as β-glucans, upon gut health.

“…In the present study, these variances significantly affected all egg production traits except EWAFE, where the GCA effect was non-significant. The higher PE in KK and WL for most traits would manifest higher additive and dominance genetic variances and the existence of favorable alleles in these breeds, according to Nath et al ( 2014 ). The results also suggest that these breeds might have undergone improvements in egg production.…”

“…According to different authors (Nath et al, 2007 , 2014 ; Rajkumar et al, 2011 ), the significant variation in ME suggests the influence of maternal additive and dominance gene effects. Other authors (El-Tahawy, 2020 ; Hussen et al, 2020 ) also reported a significant variation due to ME in EM and EN.…”

The present study estimates additive and non-additive effects on egg production traits in genotypes generated through pure mating and reciprocal crossing of Fayoumi (FM) with Koekoek (KK) and White Leghorn (WL). Age at first egg (AFE) and body weight at first egg (BWAFE) were determined when the first bird in the pen laid its first egg, and egg weight at first egg (EWAFE) was the average weight of eggs laid consecutively during the first 10 days. Egg number (EN) and egg weight (EW) were recorded daily from AFE to 40 weeks of age. Egg mass (EM) was the product of EN and EW. EN of hens initially housed and hens alive during the experiment were used to calculate hen-housed egg production (HHEP) and hen-day egg production (HDEP), respectively. All the traits showed statistically significant differences among the genotypes. The results revealed the importance of additive and non-additive effects, where purebred effect (PE), general combining ability (GCA), maternal effect (ME), specific combining ability (SCA), and residual reciprocal effect (RRE) significantly affected most of the traits. The KK and WL had a higher PE, and GCA was highest in KK, with FM and WL showing a higher ME. The FM x WL had higher SCA and RRE. The KK x FM and FM x WL outperformed their main and reciprocal crosses, respectively, and purebred contemporaries. Therefore, a synthetic breeding program involving KK as a sire and FM, WL, FM x WL, and KK x FM as a dam would be feasible.
