Diagnosis before treatment: Identifying dairy farmers’ determinants for the adoption of sustainable practices in gastrointestinal nematode control

Sustainability has been an emerging issue for years in the economy and agriculture. Making agriculture sustainable has become so essential that it has become part of the Common Agricultural Policy (CAP). However, producers ultimately decide individually the practices they implement. This is why farmers play a central role in ensuring a sustainable agricultural system, which results from farmers’ knowledge and expectations. Although numerous studies address sustainability issues, little is known about farmers’ knowledge and implementation of sustainable practices at different types of farms, especially in central and eastern Europe. This study aimed to determine Polish farmers’ awareness of sustainability with regards to animal and crop production. This paper also shows how farmers value the advantages arising from sustainable production. The study was carried out among 300 farms classified by type (dairy, beef cattle, pork, and crop production). The research instrument used was a questionnaire, with the Likert scale. The results show that dairy farmers and pork farmers declared higher knowledge and better implement sustainable practices than other farmers. The producers’ views on the benefits coming from sustainable agriculture varied. However, the two most significant advantages were recognized—the protection of water against pollution and the reduction of greenhouse gas emissions.

Integrated Methods

The efficacy of the anthelmintic albendazole (ALB), doramectin (DOR) and ivermectin (IVM) were evaluated in Holstein and Holstein crossbreed dairy heifers using the fecal egg count reduction test (FECRT). Dairy heifers (n=420; ~6 months of age; BW = 149 ± 39.6 kg) were evaluated in 21 dairy farms. All heifers were required to be on pasture and not have been exposed to anthelmintic treatment for a minimum of 3 months. At each dairy farm, a priori, groups of at least 18 heifers were randomly divided to be treated with IVM, or DOR, or ALB following manufacturer's instructions. Fecal samples were collected directly from the rectum 7 days before anthelmintic treatment (d-7), at the time of the treatment (d0), and 14 days after treatment (d14). Only heifers that had an average FEC ³ 100 eggs per gram of feces (average of FEC from day d-7 and d0) were considered in the FECRT. The FECRT was determined by the modified McMaster technique. Of the three-anthelmintic used, ALB (n=142) proved to be the most effective (P < 0.0005) with an efficacy of 67.47% ± 8.43. The efficacy of DOR and IVM did not differ (P = 0.8713). While DOR (n = 130) exhibited a efficacy of 25.50% ± 18.00, IVM (n = 148) exhibited a efficacy of -8.13% ± 19.89 due to an increase in FEC after treatment. Dairy farmers should implement integrated methods of nematode control to preserve the effectiveness of currently available anthelmintics.
