Última Artificial insemination system without estrous observation in suckled beef cows Ciência Rural Borges,Luiz Felipe Kruel; Ferreira,Rogério; Siqueira,Lucas Carvalho; Bohrer,Rodrigo Camponogara; Borstmann,Jacson William; Oliveira,João Francisco Coelho de; Gonçalves,Paulo Bayard Dias. The aim was to develop a timed artificial insemination (TAI) system in suckled beef cows. Cows (n=227), 60-80 days postpartum, received estradiol benzoate (5mg) and a vaginal device containing 250µg of medroxyprogesterone acetate (MPA; day 0). On day six, cloprostenol (125µg) and eCG (400IU) were administrated and calves were weaned for 88h. The devices were removed on day seven (BioRep group) or on day eight (TAI group). All cows of TAI group and cows of BioRep group that did not exhibit standing estrus received GnRH (100µg) on day 9. In experiment I, the follicular growth was monitored daily by transrectal ultrasound exams, from day 6 to day 9. The average size of the dominant follicle on day nine was 11.1±0.99mm (BioRep, n=7) and 11.5±0.65mm (TAI, n=7)...

Mol. Biol. Gonçalves,Iara Denise Vasconcellos; Gonçalves,Paulo Bayard Dias; Silva,Janandra Cortese da; Portela Jr,Valério Valdetar; Borges,Luiz Felipe Kruel; Oliveira,João Francisco Coelho; Lovatto,Paulo Alberto. The aim of the present study was to investigate the association of the estrogen receptor (ER-PvuII) and retinol-binding protein 4 (RBP4-MspI) gene polymorphisms and their interactions with prolificacy in a commercial synthetic pig line reared in Brazil. A total of 10,374 piglet records from 218 sows and 817 litters were used for litter size analysis. Only females with three or four farrowings were included in the analysis. The mean litter size ranged from 5.0 to 19.5 piglets. DNA was extracted from leukocytes by a standard method, and ER-PvuII and RBP4-MspI polymorphisms were characterized by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. The association between alleles or genotypes and reproductive performance...
