Research ArticleOpen accessIn the abstractSeasonal Variations in Semen Quality of Pasundan Bulls in their Native Tropical EnvironmentNurul Isnaini, Tri Harsi, Anggit Damaratri Lapoliwa et al.The success of artificial insemination highly depends on the semen quality, in which it may significantly associate with the environmental factor. However, the information regarding the seasonal effects on semen quality of Pasundan bulls is still scarce. This study aimed to examine seasonal variation in semen quality of Pasundan bulls in their native environment. A total of 203 ejaculates produced … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 27 Apr 2021 · 7,931 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Different Freezing Curves on the Acrosome Integrity of Male Goat Sperm CellsSofia Alexandra Fagundes Lopes, Henrique José Duarte Rosa, António Chaveiro, Fernando Moreira da SilvaThe aim of the present study was to evaluate the effect of three different freezing curves on male goat’s sperm viability and acrosome integrity. Semen was collected on three adult male goats in February (Azores, Portugal, latitude 38°39′N) using an artificial vagina and a female with induced heat. Three collection sessions were spaced of approximately 5 days. The study followed … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 19 Feb 2021 · 6,616 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFrom Plastic Waste to Building Material: Mechanical Properties of Recycled Thermoplastic TimberMonica Valdés, Nicoletta Trulli, Barbara De NicoloThe present paper illustrates the mechanical properties of a new structural product called Recycled Thermoplastic Timber (RTT), manufactured in Sardinia (Italy) and made of recycled plastics. The preliminary results of an experimental campaign aimed at assessing the main mechanical and physical properties of RTT are presented and discussed. Unreinforced and steel-reinforced thermoplastic timber profiles have been tested in laboratory and … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 23 Feb 2018 · 13,406 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvidences for the Role of Melatonin as a Protective Additive During Buffalo Semen FreezingMohamed El-Raey, M. R. Badr, Z. M. Rawash, G. M. DarwishTill now, the exact role of melatonin in male infertility hasn’t been fully discovered. Moreover, the intracellular signaling pathways activated by melatonin in buffalo spermatozoa especially on the level of cryopreservation process haven’t been reported. The current study aimed simply to clarify the precise role of this hormone during buffalo semen cryopreservation. Semen samples were obtained randomly from 6 fertile … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 4 · 23 Dec 2014 · 8,112 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUse of Quinolones in Bull Semen Extenders to Reduce Sperm Deoxyribonucleic Acid DamageClara Gonzalez-Marin, Michael Eduard Kjelland, Rosa Roy et al.Cryopreserved sperm samples from Holstein bulls (n = 20) were examined for bacterial presence and Sperm DNA Fragmentation (SDF) dynamics. SDF was assessed after thawing (T0) and at 4, 24 and 48 h of incubation (37°C) and the rate of SDF (r-SDF), as an estimator of the DNA degradation over time, was calculated. Two groups of bulls were identified based … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 29 Dec 2012 · 7,430 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Age and Postmortem Time on Some White-Tailed Deer (Odocoileus virginianus texanus) Epididymal Sperm Characteristics and Response of CryopreservationJ. Ake-Lopez, E. Cavazos-Arizpe, J. G. Magana-Monforte et al.Problem statement: Males rather than females of the White-Tailed deer (Odocoileus virginianus texanus) are more susceptible to hunting because their physical characteristics, therefore their elimination can increase a genetic degradation and a lower productivity because of the effect of gender. Thus, the aim of the current study was to evaluate the effect of age and postmortem time of White-Tailed deer … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 7,623 accessesView PDF Cite
