Trends and challenges in liquid-preserved boar semen production: From boar to product.

Boar semen production plays a pivotal role in modern swine breeding programmes, influencing the genetic progress and overall efficiency of the pork industry. This review explores the current challenges and emerging trends in liquid-preserved boar semen production, addressing key issues that impact the quality and quantity of boar semen. Advances in new reproductive technologies, boar selection, housing, semen processing, storage and transport, and the need for sustainable practices including the use of artificial intelligence are discussed to provide a comprehensive overview of the field.

Acinetobacter in fresh faecal samples is related to sperm motility: A case report in Piétrain boars housed on different deep-litter bedding materials.

The swine gastrointestinal tract contains a great variety of microbes, forming a complex and dynamic ecosystem. Various internal and external factors (e.g.

Comparison of deep-litter bedding materials and analysis of semen traits in Piétrain boars: A randomized controlled field study.

External factors can affect reproductive traits of breeding boars and especially the sensitive process of spermatogenesis. The aim of this study was to investigate probable influences of bedding materials (chipsy wood shavings (CWS), hemp straw (HS), linen straw (LS), spelt husks (SH), and regional wood shavings (RWS)) on semen traits of 40 randomly selected Piétrain boars (8 boars per group, age: 2.35 ± 1.
