The season, the lunar phase, meteorological parameters and farm management factors were investigated to determine which ones affect pregnancy rate. A total of 250 \u00cele-de-France ewes were inseminated by laparoscopy in spring (March, April) and in autumn (October, November). In the autumn season, only 20.0% of the inseminated ewes became pregnant while in spring, this was 51.3%. In the spring season, an extreme change in minimum temperature affected negatively the probability of conception (\n                    <jats:italic>P<\/jats:italic>\n                    = 0.0692), within the four days preceding insemination. Increased variance in the maximum and minimum temperature decreased the probability of conception (\n                    <jats:italic>T<\/jats:italic>\n                    <jats:sub>max<\/jats:sub>\n                    :\n                    <jats:italic>P<\/jats:italic>\n                    = 0.0472;\n                    <jats:italic>T<\/jats:italic>\n                    <jats:sub>min<\/jats:sub>\n                    :\n                    <jats:italic>P<\/jats:italic>\n                    = 0.033) within 40 days after insemination. Spring inseminations resulted in a significantly higher number of twin pregnancies (29.23%) compared with autumn inseminations (12.73%). The proportion of twin pregnancies was lower (21.90%) in the waning moon period compared to the waxing moon period (28.47%). None of the examined farm management factors had an effect on pregnancy. In our humid-temperate continental climate (in Hungary), spring laparoscopic inseminations were more effective in \u00cele-de-France sheep, with weather conditions potentially influencing the outcome.\n                  <\/jats:p>","DOI":"10.1556\/004.2025.01217","type":"journal-article","created":{"date-parts":[[2026,1,6]],"date-time":"2026-01-06T14:27:10Z","timestamp":1767709630000},"page":"41-47","update-policy":"https:\/\/doi.org\/10.1556\/policypage.crossmark.crossref.2","source":"Crossref","is-referenced-by-count":0,"title":["Factors influencing the success of laparoscopic artificial insemination in \u00cele-de-France sheep breed"],"prefix":"10.1556","volume":"74","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-3693-0896","authenticated-orcid":true,"given":"Melinda","family":"Bagi","sequence":"first","affiliation":[{"name":"Doctoral School of Animal Science, University of Debrecen, B\u00f6sz\u00f6rm\u00e9nyi Street 138, H-4032, Debrecen, Hungary"},{"name":"Department of Animal Husbandry, Faculty of Agricultural and Food Sciences and Environmental Management, Institute of Animal Science, Biotechnology and Nature Conservation, University of Debrecen, H-4032, Debrecen, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L\u00e1szl\u00f3","family":"Huzsvai","sequence":"additional","affiliation":[{"name":"Department of Quantitative Methodology, Faculty of Economics and Business, Institute for Methodology and Business Digitalisation, University of Debrecen, H-4032, Debrecen, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Attila Csaba","family":"Dobos","sequence":"additional","affiliation":[{"name":"Centre for Precision Farming R&D Services, FAFSEM, University of Debrecen, H-4032, Debrecen, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Csaba","family":"R\u00e1cz","sequence":"additional","affiliation":[{"name":"Centre for Precision Farming R&D Services, FAFSEM, University of Debrecen, H-4032, Debrecen, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriella","family":"K\u00fatv\u00f6lgyi","sequence":"additional","affiliation":[{"name":"Department of Precision Animal Breeding and Livestock Biotechnology, Institute of Animal Sciences, Hungarian University of Agriculture and Life Sciences, H-2053, Herceghalom, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N\u00f3ra","family":"Vass","sequence":"additional","affiliation":[{"name":"Department of Animal Husbandry, Faculty of Agricultural and Food Sciences and Environmental Management, Institute of Animal Science, Biotechnology and Nature Conservation, University of Debrecen, H-4032, Debrecen, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"425","reference":[{"key":"B1","series-title":"J.\u00a0Anim.
