Reproductive efficiency is an essential requirement for the profitability of swine farms and the quality of fodder can have a negative impact on this aspect. We carried out investigations regarding the influence of fodder quality on reproductive efficiency and the histological structure of the ovary and oviduct in 45 sows from a farm in Bihor county. We observed that corn utilized in feeding the sows was stored in inadequate conditions which allowed the development of moulds. The combined fodder, resulted after grinding the cereals, was stored directly on the concrete floor in inappropriate areas, concerning the hygiene. The animals were given green fodder directly on the stall’s floor, which favours mould expansion. Upon histological examination, the ovary presented an exaggerated activity and there was a marked congestion in the oviduct, with a tendency of the epithelium toward pseudostratification. The precarious conditions of cereal and combined fodder storing and administration of green fodder, brought optimum conditions for mould development. Under the action of the latter factors, the reproductive performance drastically decreased along with compromising the sows used for reproduction.
