The effect of age, interval collection and season on selected semen parameters and prediction of AI boars productivity

The possibility of planning the production level has a special importance for AI stations, and its inaccuracy should be minimized by eliminating the factors differentiating the quantity and quality of the ejaculate.

A comparative study of the effects of Escherichia coli and Clostridium perfringens upon boar semen preserved in liquid storage

The effects of infection by E. coli were dependent of both bacterial load and storage period, whereas the effects of C. perfringens were mainly dependent on the bacterial load.

Control points in the preparation of semen doses: temperature control and quality parameters (1/2)

The impact of semen used for post-cervical AI is 2-3 times bigger than that used to produce cervical insemination doses; therefore, preparation of the doses should follow an even stricter control program.

The dependence of the growth rate and meat content of young boars on semen parameters and conception rate

The objective of the research was to conduct semen parameter and conception rate analyses on the basis of growth rate and meat content.

Fig. 4: Schematic illustration of the topography of the testis and epididymis in boars, with suggested transducer placement when assessing the epididymal caput (= head; a), corpus (b) and cauda (= tail; c). The caput and cauda are best imaged longitudinally and the corpus transversally (from Kauffold et al., 2011).

Use of B-Mode ultrasonography to examine the genital tract of boars

This tool allows prediction of potential ejaculate yield and to aid in diagnosing subfertility/infertility associated with diseased tissues.

A sow approaches a boar within a group gestation pen. The pen design allows nose-to-nose contact between the animals, allowing for pheromone exchange to trigger heat response if the sow is open. The technology records the number and length of interactions and calculates whether the sow’s behavior indicates she is in heat.

Effect of Pseudomonas aeruginosa on sperm capacitation and protein phosphorylation of boar spermatozoa

The present study provides novel data regarding the effects of bacterial contamination on boar sperm, suggesting that the presence of P aeruginosa affects the fertilizing ability of boar sperm by altering its ability to accomplish IVC.
