Reproductive Behavior of Zebu and 5/8 Zebu x 3/8 Simmental Genotypes in Central Cuba Locations
The aim of this paper was to evaluate the reproductive behavior of female Zebu and 5/8 Zebu x 3/8 Simmental on a genetic farm in the central region of Cuba. The research was made between 2010 and 2014. The individual records of 255 cows; 200 Zebus (106 white and 94 bermeja) and 55 crossbreds (5/8 Ze...

Zusammenfassung: | The aim of this paper was to evaluate the reproductive behavior of female Zebu and 5/8 Zebu x 3/8 Simmental on a genetic farm in the central region of Cuba. The research was made between 2010 and 2014. The individual records of 255 cows; 200 Zebus (106 white and 94 bermeja) and 55 crossbreds (5/8 Zebu x 3/8 Simmental) were included. The calving-first insemination interval (CFII), calving-gestation interval (SP), inter-calving period (CCI), and service per gestation (S/G) were calculated. Besides, the effects of genotype, parity, quarter and calving year were evaluated using the above indicators. The descriptive statistics were estimated, and a general linear model was used to determine the effects of each variation source. The three genotypes showed low reproductive efficiency, though slightly more favorable for 5/8 Zebu x 3/8 Simmental. The CFII, SP, and CCI were influenced (P |
