Última Comparison between deep intracornual artificial insemination (dIAI) and conventional artificial insemination (AI) using low concentration of spermatozoa in beef cattle BABT Meirelles,Ciro; Kozicki,Luiz Ernandes; Weiss,Romildo Romualdo; Segui,Marcio Saporski; Souza,Antonio; Santos,Ivo Walter dos; Breda,Jose Carlos dos Santos. This study aimed to compare the pregnancy rate using the conventional artificial insemination (AI) or deep intracornual artificial insemination (DIAI), with low number of spermatozoa (4.0 million sperm) in 270 Nelore cows. The animals were divided in two groups (G: G1 (135 cows) conventional AI was performed (=semen deposition in the uterine body) and in G2 (135 cows) to DIAI, in ipsilateral horn where the dominant follicle in the ovary had previously been detected, by ultrasound examinations. For both the methods, a single artificial insemination was carried out after visual estrus observation, checked three times a day (morning, afternoon and evening). The pregnancy diagnosis after 45 days was conducted by ultrasound. Results showed a better pregnancy...

Sci. MEIRELLES,Cyro Ferreira; VITTI,Dorinha Miriam Silber Schmidt; ABDALLA,Adibe Luiz. Effects of temporary calf removal and phosphorus supplementation on conception rate in a 60 or 120 day breeding season period was observed in several trials conducted over three years on Nelore cows. Experiment I involved 47 acyclic Nelore cows with suckling calves ranging in age from 55 to 70 days. Calves were temporarily removed from their dams for 48 h at the beginning of the trial or stayed with the dams throughout the trial. The proportion of cows that cycled during the breeding season was 5 out of 25 (20%) in the control group and I5 out of 22 (68%) in the group whose calves had been removed (p<0.05). In Experiment II, 66 acyclic Nelore cows, averaging 60 ± 0.57 (x ± SE) days post-partum were allocated at random in three groups as follows: A,...
