The goal of nutrigenomics is to study nutrients as signals that are received by cellular receptors, which can affect the genome, gene expression and metabolite production. In this research, to investigate the effect of cannabis seed on the fold change of carnitine palmitoyl transferase-1-B (CPT1B) expression in Baluchi sheep, 12 five-month-old male lambs were divided into two groups in a completely randomized design. The groups were fed with a control diet without cannabis seed and with a diet containing 10% cannabis seed. After the fattening period of 110 days, samples were taken from the heart, liver, testis, subcutaneous back fat and Longissimus dorsi muscle. Total RNA was extracted for Real Time PCR reaction and measurement of CPT1B gene expression change between groups. The change of CPT1B gene expression in liver tissue was significant between control and treatment groups (P<0.05). The expression of CPT1B gene was 5.74 times higher in liver of lambs treated with Cannabis seed compared with the control group. The CPT1B gene expression in heart, subcutaneous back fat, Longissimus dorsi muscle, and testis decreased by 3.1, 2.36, 2.12 and 2.47 times, respectively compared to control group. Cannabis seeds contain unsaturated fatty acids and these compounds can change the fat metabolism in the liver through the expression of genes such as CPT1B. Therefore, it can be stated that, CPT1B is one of the effective genes in fat metabolism and the addition of cannabis seeds to the diet can have a beneficial effect on the animal's production performance by increasing the activity of the liver tissue.

This wok was conducted to identify polymorphisms in the region of the exon 1 in 5'UTR of myostatin gene and their relationships with the growth traitsin Raeini cashmere goats. Myostatin gene has been identified as a factor causing a phenotype known as double-muscling in which a series of mutations render the gen inactivity; therefore, able to increase muscle growth. Blood samples were randomly taken from 150 Raeini cashmere goats. Total genomic DNA was extracted and a 701 bp fragment was amplified from the exon 1 of myostatin gene using PCR-RFLP method. The analysis of band patterns indicated three genotypes including AA, AB and BB with frequencies of 0.56, 0.33 and 0.11, respectively. The A and Balleles had a frequency of 0.72 and 0.28, respectively. The analysis of additive and dominance gene actions revealed that the effect of the myostatin gene on growth traits and body size of Raeini cashmere goats is via the dominance mechanism. The results showed that all growth traits except weaning weight were significantly associated with the identified polymorphisms, thus this gene can be used as a molecular marker in Raeini cashmere goats breeding.

This study aimed to identify genes that show signatures of selection for mutations in Iranian native cattle breeds. The data consisted of genotypes for ~777962 SNP markers of 90 animals from eight Iranian native cattle breeds distributing over the country. Therefore, the aim was to identifying divergently selected regions of the genome. Study of population differentiation across the genome using Weir and Cockerham’s FST test revealed some regions showing evidence of selection. Across the 30 bovine chromosomes (BTA), seven putative selection signatures were detected. These regions were located on chromosomes 1, 2, 7, 8, 12, 13 and X. Finally, study of the reported QTL regions in the orthologous areas of the cattle genome showed that the genomic regions identified in this study overlapped with the reported QTL representing economically important traits such as milk yield, cold tolerance and reproductive traits. Result of this research provided important information on existence of genetic diversity and selection signatures in Iranian native cattle.
