Cím:	Effects of temperament on production and reproductive performances in Simmental dual-purpose cows / Cziszter Ludovic Toma, Gavojdian Dinu, Neamt Radu, Neciu Florin, Kusza Szilvia, Ilie Daniela-Elena

Megjegyzések:	The aim of the current research was to evaluate the effects that temperament has on production and reproduction performances in Simmental dual-purpose cattle breed. Behavioral reactivity of cows significantly influenced (P <= 0.05) the body weight, milk yield, fat yield, protein yield, protein content, and the calving interval of the cows included in the study-head, having more substantial effects (P <= 0.001) on the milking speed and the number of steps per day, with calmer cows outperforming the nervous counterparts. However, temperament did not influence (P > 0.05) traits such as days open, number of inseminations per gestation, fat percentage, somatic cell count, body condition score, cleanliness of udder and cleanliness of hindquarter. Significant negative phenotypic correlations were found between temperament and cows body weight (-0.19), milk yield (-0.19), fat yield (-0.14), protein yield (-0.18), and milking speed (-0.18). Current results suggest that selection for calm temperaments will translate into increased milk, fat, and protein yields in Simmental cattle, as well as shorter the calving interval and improved milk ejection.

Cím:	Kompetitive Allele Specific PCR Genotyping of 89 SNPs in Romanian Spotted and Romanian Brown Cattle Breeds and Their Association with Clinical Mastitis / Daniela Elena Ilie; Dinu Gavojdian; Szilvia Kusza; Radu Ionel Neamț; Alexandru Eugeniu Mizeranschi; Ciprian Valentin Mihali; Ludovic Toma Cziszter

Megjegyzések:	Mastitis is the most common production disease in the dairy sector worldwide, its incidence being associated with both cows` exposure to bacteria and the cows` genetic make-up for resistance to pathogens. The objective of our study was to analyse 89 missense SNPs belonging to six genes (CXCR2, CXCL8, TLR4, BRCA1, LTF, BOLA-DRB3), which were found to be associated with genetic resistance or susceptibility to mastitis. A total of 298 cattle (250 Romanian Spotted and 48 Romanian Brown) were genotyped by Kompetitive Allele Specific PCR (KASP) and a chi-squared test was used for genetic association studies with clinical mastitis. A total of 35 SNPs (39.3%) among the selected 89 SNPs were successfully genotyped, of which 31 markers were monomorphic. The polymorphic markers were found in two genes: TLR4 (rs460053411) and BOLA-DRB3 (rs42309897, rs208816121, rs110124025). The polymorphic SNPs with MAF > 5% and call rates > 95% were used for the association study. The results showed that rs110124025 in the BOLA-DRB3 gene was significantly associated with mastitis prevalence (p ? 0.05) in both investigated breeds. Current results show that the SNP rs110124025 in the BOLA-DRB3 gene can be used as a candidate genetic marker in selection for mastitis resistance in Romanian dairy cattle.
