Research ArticleOpen accessThe Effect of Early Weaning on Performance, Health Parameters, and Carcass Traits of Bonsmara Bull Calves Under Feedlot ConditionsKgotso Patrick Matli, Thobela Louis Tyasi, Pieter FourieA feedlot is an intensive farming system used for finishing livestock. This study analyzed the performance, health, and carcass traits of Early-Weaned Calves (EWC) and Traditionally-Weaned Calves (TWC). A total of 285 Bonsmara bull calves were grouped into two weaning strategies, with 136 EWC (255±27.30 kg) and 149 TWC (308±24.60 kg). Backgrounding was followed by a finishing phase, with a … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 14 Aug 2026 · 1,233 accessesView PDF Cite

Review ArticleOpen accessImpact of Poxvirus Infection on Crocodile Skin Quality: A Systematic ReviewPretty Rachuene, Khetho Ratshilumela Nemutandani, Joseph Thinawanga Mugwabana, Thobela Louis TyasiCrocodile poxvirus infection causes small superficial lesions covered by dark brownish crusts or scabs. This infection is of importance in crocodile farming due to its potential impact on the tanned hide. The objective of this study was to systematically review literature on the effect of poxvirus infection on crocodile skin quality. The study systematically used four search engines: Google Scholar, … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 11 Aug 2026 · 1,009 accessesView PDF Cite

Review ArticleOpen accessGoats’ Litter Size Concerning Bone Morphogenetic Protein 15 Gene VariationsTebogo Letsukulo Percy Thepa, Thobela Louis Tyasi, Jones Ng’ambiBone morphogenetic protein 15 (BMP15), a member of the transforming growth factor-β (TGF-β) superfamily, plays essential roles in follicular development and ovulation. Single nucleotide polymorphisms (SNPs) in the BMP15 gene have been associated with litter size in multiple livestock species, yet no comprehensive systematic review has synthesized findings across goat breeds. This systematic review aimed to evaluate the association between … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 18 Feb 2026 · 1,405 accessesView PDF Cite

Literature ReviewOpen accessPrediction of Body Weight from Linear Body Measurements in Sheep: A Systematic ReviewMathemba Kwezi Molosi, Lubabalo Bila, Thobela Louis TyasiThe aim of the study was to systematically review the literature on the prediction of the body weight from linear body measurement traits in sheep using four databases: Google Scholar, PubMed, Science Direct and Web of Science. The findings showed that eighteen (n = 18) articles with22% (n = 4) were from South Africa certified to be utilised in this … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 2 · 5 Jul 2025 · 3,543 accessesView PDF Cite

Research ArticleOpen accessComparison of Multivariate Adaptive Regression Splines and Classification Regression Tree for Prediction of Body Weight of Bapedi SheepMadumetja Cyril Mathapo, Ramaisela Barley Mthembu, Albino Joas Tsenane et al.The study aimed to compare the performance of multiple adaptive regression splines and classification regression trees for the prediction of the body weight of Bapedi sheep. A total of 100 Bapedi sheep aged between one and five years old of different sexes were employed. The study measured the following: Body Length (BL), Withers Height (WH), Heart Girth (HG), Rump Height … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 12 Jul 2024 · 5,184 accessesView PDF Cite

Research ArticleOpen accessUsing Morphometric Traits to Estimate Live Body Weight of South African Bapedi SheepThabang Sako, Jones Ng’ambi, Thomas Raphulu et al.This study was carried out for the estimation of Body Weight (BW) of bapedi sheep from Body Length (BL), Sterna Height (SH), Heart Girth (HG), Height at Withers (WH), Rump Height (RH) and Head Length (HL). Correlation and regression were used. Correlation displayed that body weight is highly positively associated (p<0.01) with WH and HG in males while for females, … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 26 Jun 2024 · 5,651 accessesView PDF Cite

Literature ReviewOpen accessSystematic Review of Single Nucleotide Polymorphisms of Cattle Beta-Lactoglobulin Gene and their Association with Milk Production TraitsThlarihani Cynthia Makamu, Thobela Louis TyasiThe application of molecular genetics technology to pinpoint certain DNA markers associated with commercially significant features is highly anticipated since it has the potential to enhance the effectiveness of breeding programs by selecting young animals early for use as future breeding stock. One of the main genes expressed in bovine milk is the Beta-Lactoglobulin Gene (βLG), and its polymorphism can … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 4 Mar 2024 · 5,811 accessesView PDF Cite

Research ArticleOpen accessGrowth Traits as Indicators of Body Weights in Dorper SheepMolabe Kagisho Madikadike, Vusi Mbazima, Busisiwe Gunya, Thobela Louis TyasiThe growth traits help rural farmers who lack weighing equipment to anticipate the body weights of their animals for a variety of reasons, including feeding, medication, and breeding purposes. The study aims to predict body weights from the growth traits of Doper sheep. Data on growth traits such as body length, heart girth, sternum height, withers height, rump height, and … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 4 · 26 Dec 2022 · 6,287 accessesView PDF Cite
