Incorporation of a Statewide Webinar Series into an Existing County-based Beef Cattle Extension Program

Abstract With the objective of continuing educational delivery while county Extension offices were unable to host large group meeting due to pandemic response regulations, a series of webinars were developed as a component of the Tennessee Master Beef Producer program. A secondary objective was to maintain a county-based approach to programmatic delivery. To reach these objectives, individual webinars (Zoom Video Communications, San Jose, CA; n = 9), each lasting approximately 1.5 hr were developed by UT Extension Specialists and offered between October and November of 2020 covering the topics of breeding and genetics, reproductive management, nutrition, animal handling, economics, health management, and forages. Questions were administered during the live session via the Zoom polling function to assess production statistics and collect evaluation data. The series was advertised in local communities through UT Extension County Agents. Agents were given the opportunity to choose as many or as few to incorporate into their local delivery and could choose to give producers the option of viewing at home, at socially distanced group meetings, or either. Interaction was limited to the chat function within Zoom with the expectation that attendees would make audio and video interaction difficult to manage. Total live participation was 8,009 and averaged 890 ± 15.3 unique views per session. Each webinar was recorded and posted to YouTube to be used by agents for later delivery. In-webinar polling showed that an average of 91% of the webinar participants planned to implement a change on their operation as a direct result of information provided in the presentation. Post-webinar Likert scale (1 to 5) analysis of participants indicated approval of speaker ability (4.52 ± 0.03) and content quality (4.51 ± 0.03). These results indicate a high adoption rate by agents and that webinars are an effective tool for achieving behavioral change through a county-based Extension system.

Reducing animal handling and costs in timed artificial insemination (TAI) systems are of great interest in animal production, regardless of the species. Thus, this study was carried out to investigate the effects of administering oestradiol cypionate (EC) or hCG to induce ovulation in buffalo (Bubalus bubalis) in TAI programs. The 79 Bufalipso heifers housed at Institute of Animal Science, San José de las Lajas, Cuba, were, on average, 24 months of age with a body weight of 310 to 380 kg at the beginning of the experiment. The investigation was conducted out of the breeding season (25 June through 28 July 2012). Heifers were randomly assigned to 1 of 3 treatment groups; either hCG (control group) or EC1 and EC2, in which TAI was performed at either 48 or 56 h after the EC injection, respectively. On the first day of the treatment regime (Day 0), animals received oestradiol benzoate (2 mg i.m.; Sincrodiol®, Ourofino, Brazil), followed by the insertion of an intravaginal device containing 1 g of progesterone (Primer®, Tecnopec, São Paolo, Brazil). On Day 9, an intramuscular luteolytic dose of cloprostenol (500 μg; Ciosin®, Intervet, Brazil) and eCG (500 UI; Novormon®, Intervet) were given in all heifers along with the removal of the intravaginal device. On the same day, 0.5 mg of EC (ECP®, Pfizer, Brazil) was administered intramuscularly in the EC1and EC2 groups. Animals in the hCG group received hCG (1000 IU i.m.; Vetecor®, Hertape Calier, Spain) on Day 11 and were inseminated 14 h later. Pregnancy diagnosis was performed by ultrasound 35 days after TAI. Data were analysed by a chi-squared test, with P < 0.05 taken as significant. There were no differences among treatment groups, with values of 57.7 (15/26), 60.7 (17/28), and 64% (16/25) for the EC1, EC2, and hCG groups, respectively. In conclusion, oestradiol cypionate was effective at inducing ovulation in buffalo heifers in TAI programs comparable to the control group, as evidenced by the conception rates. In addition, animals subjected to the EC protocol pass just 3 times through the corral instead of 4 when receiving hCG, which decreases the animal handling and costs.

Value Added Products

The future competitiveness of any nation, including its agriculture, is inextricably tied to understanding and effectively participating in global markets. Major opportunities exist for farmers to produce, process, and export agricultural products, especially value added products, if they had knowledge of global opportunities. Most of the information and services are available for them to achieve this objective. The Cooperative Extension System (CES) can provide a mechanism to deliver educational programs on global marketing opportunities and training on procedures for capitalizing on these opportunities. County agents from Virginia and California working with their mushroom producers helped them respond to a year round shitake order from the United Kingdom. This has resulted in an ongoing market for these producers. Other similar examples in horticulture will be discussed.

Covalent Bonds

The structural damage of molecules irradiated by electrons is generally considered to occur in two steps. The direct result of inelastic scattering events is the disruption of covalent bonds. Following changes in bond structure, movement of the constituent atoms produces permanent distortions of the molecules. Since at least the second step should show a strong temperature dependence, it was to be expected that cooling a specimen should extend its lifetime in the electron beam. This result has been found in a large number of experiments, but the degree to which cooling the specimen enhances its resistance to radiation damage has been found to vary widely with specimen types.

Körperliche Beschwerden

Körperliche Beschwerden sind bei Älteren weit verbreitet; diese sind bei Migranten bislang in Deutschland und international noch wenig untersucht. Unsere multizentrische Querschnittstudie erfasste körperliche Beschwerden bei Menschen im Alter zwischen 60 und 84 Jahren mit Wohnsitz in Stuttgart anhand der Kurzversion des Gießener Beschwerdebogens (GBB-24). In Deutschland wurden 648 Personen untersucht, davon 13.4 % (n = 87) nicht in Deutschland geborene. Die Geschlechterverteilung war bei Migranten und Nichtmigranten gleich; der sozioökonomische Status lag bei den Migranten etwas niedriger: 8.0 % (n = 7) der Migranten und 2.5 % (n = 14) der Nichtmigranten verfügten über höchstens vier Jahre Schulbildung; 12.6 % (n = 11) der Migranten und 8.2 % (n = 46) der Nichtmigranten hatten ein monatliches Haushaltsnettoeinkommen von unter 1000€; 26.4 % der Migranten und 38.1 % (n = 214) der Nichtmigranten verfügten über mehr als 2000€ monatlich. Somatische Beschwerden lagen bei den Migranten bei 65.5 % (n = 57) und bei den Nichtmigranten bei 55.8 % (n = 313). Frauen wiesen häufiger somatische Beschwerden auf (61.8 %) als Männer (51.8 %). Mit steigendem Alter nahmen somatische Beschwerden zu. Mit Ausnahme der Altersgruppe der 70–74-Jährigen konnte kein signifikanter Unterschied zwischen Migranten und Nichtmigranten hinsichtlich der Häufigkeit körperlicher Beschwerden gezeigt werden. Ausblick: Es werden dringend bevölkerungsrepräsentative Studien zu körperlichen Beschwerden bei Migranten benötigt.
