RESUMO
This study aimed to evaluate the age of the first calving of buffaloes (AFC) from a buffalo herd and toevaluate the influence of the blood level in the AFC. Five hundred and eight data were analyzed between 2000and 2015 of buffalo females, Murrah breed, and dairy mixed breeds maintained in an intensive system andsubmitted to two daily milking. Statistical data were evaluated in the SAS software (2010), for the analysis of thedifferent experimental conditions, analysis of variance (ANOVA) and Tukey test with significance level of 5%.The mean value found for AFC was 38.9 ± 5.5 months (1170 days), the AFC mean value according to blood levelof Murrah breed and mixed breed was respectively 38.9 ± 5.5 months and 38.90 ± 5.3 months, (P > 0.05).Therefore, there was no influence of the blood level in the AFC.(AU)

This study evaluated the influence of the presence or absence of corpus luteum at the beginning ofartificial insemination protocol at fixed time (TAI) in pregnancy rate. 48 animals were used which prior toinsertion of releasing progesterone device were evaluated by rectal palpation for the presence or absence of thecorpus luteum, and divided into two groups: G1 cows with the presence of the corpus luteum, and G2 cows notwithout palpable structures. The data collected from individual records were tabulated in spreadsheets andevaluated in the SAS software (2000). The pregnancy rate for G1 and G2 was 40% 53.57% respectively, P >0.05. Suggesting that the presence of corpus luteum did not influence the pregnancy rate in TAI.(AU)
