Profiling of differentially expressed proteins between fresh and frozen-thawed Duroc boar semen using ProteinChip CM10

Journal of Animal Science and Technology, 2023
Many studies have been conducted to improve technology for semen cryopreservation in pigs. However, computer-assisted analysis of sperm motility and morphology is insufficient to predict the molecular function of frozen-thawed semen.

Improving manual tagging of camera trap videos for wildlife studies: a visual assistance tool applied to the endangered huillin Lontra provocax

Wildlife Biology, EarlyView.
In the last decades, the use of camera traps for wildlife studies has increased significantly due to advancements in technology leading to cost reduction and improved reliability. They facilitate the study of wild animals in their natural environment in a minimally invasive manner, eliminating the need for researchers to remain in the field for long ...

Semen characteristics of indigenous Lusitu boars compared to the Large White pig genotype reared in Zambia

Open Veterinary Journal
Background: Pigs contribute to the livelihoods of traditional pig farmers (TPFs) through meat production and economic gains. However, the production of pigs, particularly genotypes indigenous to Zambia, remains suboptimal, largely due to dominance of ...

Ban on castration of boars in the Netherlands: modeling economic consequences of options [PDF]

, 2009
As a result of social criticism on castration, the Netherlands intend to start fattening boars. The great obstacle to a ban on castration is the expected negative effect on international trade because of the fear of boar taint.

The increase in phosphorylation levels of serine residues of protein HSP70 during holding at 17ºC is concomitant with a higher cryotolerance of boar spermatozoa [PDF]

, 2014
Boar-sperm cryopreservation is not usually performed immediately after semen collection, but rather a holding time (HT) of 4 h-30 h at 17 u C is spent before starting this procedure.

Adaptive harvesting of two trophic levels stabilises predator–prey dynamics. Simulations with Eurasian lynx and European roe deer

Wildlife Biology, EarlyView.
Europe has seen the recovery of many species of wild herbivores, which are now widespread across much of the continent. In addition, large carnivores are also recolonising many European countries. Most ungulates are managed through hunting, but natural predation can also have a significant influence in many areas.

Ebermast – eine Herausforderung für den Ökolandbau [PDF]

, 2013
Das Thema Kastration von männlichen Ferkeln wird immer wieder kontrovers zwischen Landwirten, Tierschützern und Politikern diskutiert. Die Kastration mit Betäubung und/oder Schmerzmitteln ist nur teilweise eine Verbesserung.

Fertilization capacity with rainbow trout DNA-damaged sperm and embryo developmental success [PDF]

, 2010
Mammalian spermatozoa undergo a strong selection process along the female tract to guarantee fertilization by good quality cells, but risks of fertilization with DNA-damaged spermatozoa have been reported.

A Case Report on Rehabilitation of the Asiatic Black Bear (Ursus thibetanus ussuricus) in the Wild 亚洲黑熊 (Ursus thibetanus ussuricus) 野外放归野化案例报告

Wildlife Letters, EarlyView.
Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

Trajectory variance and autocorrelations within single sperm tracks as population level descriptors of sperm track complexity, predictability and energy generating ability [PDF]

, 2012
The objectives of the present study were to develop an alternative theoretical approach to the analysis of sperm motility and to develop motility parameters that would complement those more commonly used in current computer-assisted semen analysis ...
