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 PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractEffect of Repeated Freezing and Thawing on Nguni Sperm Parameters Evaluated by Computer Assisted Sperm Analyzer SystemMasindi Lottus Mphaphathi, Tshimangadzo Lucky NedambaleThe aims of the current study were to assess the effect of double freezing and thawing on Nguni semen parameters. Semen was collected from Nguni bulls. The Sperm Class Analyzer® system was used to evaluate sperm motility rates prior and post freezing, repeatedly. Semen samples were diluted with egg yolk citrate extender. Cooled semen samples were loaded into straws and … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 27 Jan 2021 · 6,591 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of the Tensioactive Agent SDS on Extender’s Boar Semen Viability after ThawingMaria Helena Moreira da Silva, Loide Valadão, Fernando Moreira da SilvaEffects of the surfactant Sodium Dodecyl Sulfate (SDS) on the motility and viability of boar semen after thawing were evaluated. For such purpose, semen of twelve adult boars was collected twice a week, the rich portion of this semen was separated and frozen with different concentrations of SDS (0; 2.5; 5; 10; 20 and 40 mM). For freezing the semen … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 20 Jan 2021 · 7,795 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeasonal Variations in Semen Parameters of Zulu Rams Preserved at 10°C for 72 H During Breeding and Non-Breeding SeasonJabulani Nkululeko Ngcobo, Khathutshelo Agree Nephawe, Ayanda Maqhashu, Tshimangadzo Lucky NedambaleThe study was conducted to evaluate the seasonal variations in semen parameters of Zulu rams preserved at 10°C for 72 h. The study site was the Agricultural Research Council (ARC) Irene, during the breeding season and the non-breeding season. Zulu rams (n = 6, age = 3 years and average weight = 35 kg ±2.29) were used in this study. … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 3 · 28 Aug 2020 · 7,302 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect Administration of Omega-3, Omega-6 and Synthetic Cholesterol on Reproductive Characteristic of Male Quail (Coturnix coturnix japonica)Abyadul Fitriyah, Supriyono, IsyaturriyadhahThe bird is one of the most important sources of animal protein for people and smallholders in developing countries. However, it is also important to look at their reproductive activity to maintain a sustainable population. Omega-3, omega-6 fatty acid and synthetic cholesterol may improve reproductive characteristics in animals including quail. Several treatments can be used to improve the quality of … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 4 · 7 Nov 2018 · 7,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Breeding Seasonality in Rusa Deer (Rusa timorensis) Stags via Serum Testosterone ProfilingWan Nor Fitri Wan Jaafar, Abd Wahid Haron, Rosnina Hj Yusoff et al.Breeding seasonality in mammals is influenced by the environmental changes and the endocrine response of the animals to that changes. Comprehension in breeding seasonality enables better reproductive management consequently maximizing the reproductive potential of the stags. Despite that, the study in breeding seasonality in Rusa deer (Rusa timorensis) is still scarce. Five healthy and matured stags were selected for this … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 1 · 19 Mar 2017 · 8,608 accessesView PDFCite
Research ArticleOpen accessIn the abstractSperm DNA Fragmentation and Apoptosis Levels: A Comparison of the Swim up and the Density Gradient Centrifugation Methods for Sperm PreparationSilvia W. Lestari, Triyana Sari, Dwi A. PujiantoThis study investigated the efficiency of two sperm preparation methods, namely, density gradient centrifugation and the swim-up method, in selecting spermatozoa based on the DNA fragmentation index and the apoptosis levels. Fifteen semen samples from infertile couples underwent sperm preparation in this study. The Makler® counting chamber and Eosin Y staining were used to analyse the sperm concentration, motility and … …OnLine Journal of Biological Sciences, Vol. 16, Issue 4 · 14 Nov 2016 · 7,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractOxidative Status of Boar Semen during StorageEraldo Zanella, Ricardo Zanella, Márcia Rósula Poetini et al.The intensification of the use of artificial insemination in the swine industry has increased the interest to develop proper conditions to store semen better for longer periods of time without affecting its fertility.
