Camels are crucial to iraq's ecology, economy, and culture for centuries, providing sustainable development through milk and meat production. they also contribute to biodiversity conservation by eating wild plants. the igf1 gene plays a significant role in camel growth, development, and adaptability, requiring research for improved management practices. this research looked at the igf1 gene's genetic polymorphism in 40 female camels in al-najaf, iraq, and how it related to the weights of the mother camel and her progeny in three age groups (weight at birth, weight after six months, and age after a year).the results were that the genotype aa had more weight than aa  and aa (646.78,601.89 and 541.00) respectively.there were significant differences between the genotypes of this gene for weight gain in the mothers' offspring from birth to subsequent weights, so Aa genotype showed superior weight gain from birth to six months of age, achieving 71.00 kg, compared to 61.44 kg for the AA and 63.60 for aa genotype. the variation in genotypes for this gene was also linked to weight gain between birth and one year of age, since the Aa type was the superior one.so the genetic hybrid model weighed 170.3 kg. this makes it evident how closely the igf1 gene in camels is related to the weight gain of both mothers and offspring , Therefore, we suggest that the hybrid genetic model be used in selecting mothers. emphasizing the need for further research on this gene and the selection of genotypes that promote greater weight gain.
