Objective: The promotion of walking could be a feasible population-level physical activity strategy because it requires little planning, is low cost and can be done year-round across settings. Community, nonprofit organisations offer one means by which to help increase walking through community programmes. The US Cooperative State Research, Education, and Extension Service has a history that spans more than a century and is known for quality in the delivery of educational programmes to help improve the lives of people in communities across the USA. The purpose of this study was to evaluate the effectiveness, feasibility and acceptability of the Get WalkIN’ intervention – an initiative supported by this programme – from the perspectives of both programme participants and county extension educators. Methods: Participants were recruited from 15 county extension sites in the Midwest region of the USA. Intervention emails targeted self-efficacy, social support, goal-setting and benefits/barriers to walking. To assess the perceptions of feasibility and acceptability of the intervention, participants and extension educators were asked to respond to a series of Likert-type scale and open-ended questions. Self-reported physical activity was assessed using the Godin Leisure-Time Physical Activity Questionnaire. Results: On average, participants and extension educators agreed that the programme was easy to use and would consider either recommending the programme to a friend or implementing the programme again within the community. Post-intervention, 69.1% of respondents were classified as sufficiently active compared to 60.5% pre-intervention. Conclusion: The use of the county-based US Cooperative State Research, Education, and Extension Service is an effective option for health promotion programming. Furthermore, a theory-based, email-mediated intervention is a valuable strategy as an independent and convenient way to facilitate increase in physical activity.

199 EFFECT OF HEPARIN CONCENTRATION ON BOVINE PREIMPLANTATIONAL DEVELOPMENT IN VITRO USING SEX-SORTED SPERM

The objective of this study was to examine the effect of heparin on bovine IVF and to improve the efficiency of IVF production by using sex-sorted sperm. The fertility performance of sex-sorted and unsorted semen from 4 bulls was compared to determine the optimal heparin concentration during preimplantational embryo development. A total of 7615 matured bovine oocytes were randomly allocated among different heparin concentrations (0, 2.5, 5, 10, 20, 40, 60, 80, and 100 μg mL–1) in Brackett-Oliphant medium and coincubated with either sex-sorted or unsorted sperm for 6 h. Presumptive zygotes were cultured in CR1aa+ 6 mg mL–1 of BSA in 5% O2 , 5% CO2 and 90% N2 at 39°C until Day 8 (Day 0, culture post-IVF). Cleavage rates at Day 2 and embryo development to blastocyst (BL) at Day 8 were recorded. Data (4 replicates) were analyzed by a general linear model (SPSS 11.0, SPSS Inc., Chicago, IL). The optimal heparin concentration for each treatment was determined as the lowest value from those groups that resulted in the highest BL rates. The results (Table 1) demonstrated that a differential requirement of heparin concentration was important for the highest preimplantational BL development between sexed sperm and unsorted control within each bull. By optimizing heparin concentration, in 3 out of 4 (75%) bulls, the in vitro BL development with sex-sorted sperm could be increased to a level that was comparable to the highest BL rate from unsorted sperm (bulls A, B, and C, P > 0.05). A higher heparin concentration was required for optimal BL development in bulls A and C; however, a lower concentration was desirable for bulls B and D, indicating that a partial capacitation to the sperm may have taken place in bulls B and D during the sorting process, as reported by Lu and Seidel (2004 Theriogenology 62, 819–830). The fertility of sorted sperm from bull D (1 out of 4, 25%) was adversely affected, even after heparin optimization for BL development (P < 0.05). This result suggests that sperm sorting could affect the IVF fertility of sorted sperm in a bull-specific manner, but it was not significant for all bulls. Table 1.
