Rabbits are important livestock animals, popular for their nutritional value. Nowadays, the molecular background of traits influencing the quality of meat and meat products is in high demand. Therefore, in the current study, we analyse the sequences of IGFBP1, IGFBP2, IGFBP4, IGFBP5, and IGFBP6 for possible polymorphisms. Based on a bioinformatics analysis in an association study on 466 animals of different breeds (New Zealand White × Flemish Giant crossbreed (9NZWxFG), Termond White (TW), Popielno White (PW), and Flemish Giant (FG)), we analyse the influence of five polymorphisms within the IGFBP genes. Statistically significant differences were found among the carcass and meat quality traits but not for all of the analysed rabbit breeds. The most promising polymorphism was g.158093018A>T within the IGFBP5 gene. The values of pH24 of m.longissimus lumborum (m.l.l.) and biceps femoris muscles (m.b.f.) were higher for the AT genotypes compared to the AA genotypes for the TW and NZWxFG crossbreeds. Also, for pH24, we found differences in ing.41594308T>C for NZWxFG, where the TT genotype values were higher than the TC values. We found differences in L*24 on m.l.l. for g.41592248A>C for NZWxFG. For m.b.f., significant differences were found in b*45 for g.3431insAC in the FG population and a*45 for g.41592248A>C and g.158093018A>T in the TW population. The shear force statistically differed for g.158093018A>T in TW rabbits and g.41592248A>C for NZWxFG. We conclude that this polymorphism may be promising for better quality rabbit meat and may be implemented in selection processes.

“…Growth traits are considered moderately to highly heritable. It must be said that growth is a non-linear process, and growth patterns can differ among animals, ages, and breeds [1,2]. As reported by Blasco et al [3], growth is decisively important in the rabbit meat husbandry.…”

“…Five SNPs were detected, two were found in exon 9, and According to Asaf et al (2014) SNPs in the coding region can directly affect the protein, SNPs in the intron region can affect splicing, while SNPs in the promoter may affect gene expression. Nevertheless, both intronic and exonic mutations can affect performance (Helal et al, 2021;Mi et al, 2021;Yadav et al, 2021). Although introns are not transcribed into proteins, many research results showed different functions of introns, one of the most important functions is increasing protein abundance.…”

This study aimed to resequencing of 962 bp of exon 9 and intron 9 of follicle stimulating hormone receptor (FSHR) gene in Pesisir cattle to identify single nucleotide polymorphisms (SNP). The samples used in this study were blood samples (n= 70) collected from Pesisir cattle (aged 2-5 years). DNA was isolated and the targeted region was amplified using the polymerase chain reaction (PCR) technique. Then the amplified products were sequenced. The results showed that the population of Pesisir cattle used in this study was polymorphic. There were 5 polymorphisms in the exon 9 and intron 9 regions, which were located at the 18 A>G, 213 T>C, +49 A>T, +232 A>C, and +252 G>A. There were 3 transition type mutations (at positions 8, 213 and +252) and 2 transversion type mutations (at positions +49 and +232). Based on the result of this study, it can be stated that the genotype frequency of Pesisir cattle population was not in the Hardy-Weinberg equilibrium.

“…Genetic improvement for heat tolerance in rabbits should rely on the local breeds which can be accurately measured by G×E interactions. Although local and native rabbit breeds generally have low productivity, they are welladapted to the local harsh environmental conditions (Helal, 2019;Helal et al, 2021). The advantages of the local breeds in the adaptation to local environmental conditions, including high ambient temperatures, were reported in different animal species, such as chickens, turkeys, ducks, goats, and sheep (Ismoyowati et al, 2019;Canales Vergara et al, 2019;Canales Vergara et al, 2020).…”

There is still a wide gap between meat demand and meat production in Egypt. This gap is becoming larger due to the direct and indirect impacts of global warming that negatively influence the grazing area and the performance of livestock. In this context, rabbits are considered as an alternative source for animal-origin meat. In the Southern Mediterranean region, the most obvious problem encountering rabbit production is the hot waves during the summer, especially during the last decades. The narrow thermo-neutral zone of rabbits makes the high temperature hinder the success of commercial production. Different strategies may assist rabbits in coping with heat stress, which are reviewed in the current study, including the improved management practices, development of new breeds, and implementation of different nutritional strategies.
