Research ArticleOpen accessIn the abstractDNA Polymorphism of Bovine Pituitary-Specific Transcription Factor and Leptin Gene Between Iranian Bos indicus and Bos taurus CattleArash Javanmard, Nader Asadzadeh, Fatollah SarhadiProblem statement: Variations at DNA level contribute to the genetic characterization of livestock populations and this may help to identify possible hybridization events as well as past evolutionary trends. Approach: The leptin and Pit-1 are attractive candidate genes for production and reproduction traits in cattle. A total of 247 Animals from four breeds from two species of Iranian cattle populations … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,024 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe 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

Literature ReviewOpen accessAll words, across the recordPhenotypic, Reproductive and Genomic Perspectives on the Status and Research Gaps of South African Bosvelder SheepNhlakanipho Sam Zulu, Khoboso Christine Lehloenya, Khanyisile Hadebe et al.The South African Bosvelder sheep is an emerging composite sheep developed from indigenous Bapedi and commercial White Dorper and Van Rooy sheep. Despite its reported adaptability and production potential under bushveld conditions, the sheep remains scientifically under-characterized and is not formally recognized within national breeding frameworks. This narrative review evaluates the current state of knowledge regarding phenotypic, reproductive, and genomic … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 1 Jul 2026 · 1,242 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEstimation of Adaptability and Stability of Nellore Sires, based on the Productive Progeny Performance Raised in Brazilian SavannaJúlio César De Souza, Fabio Fábio Rafael Leão Fialho, Carolina Fregonesi De Souza et al.The study investigates the performance and adaptability of Nellore sires across different regions, focusing on weight traits at 205 days (W205) and 550 days (W550). Analysis reveals significant variations in progeny weight means among evaluated sires, highlighting the importance of sire selection for herd improvement. Notably, certain sires consistently exhibit superior weight traits across diverse environmental conditions, indicating their potential … …American Journal of Agricultural and Biological Sciences, Vol. 19, Issue 1 · 2 Jul 2024 · 5,529 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordUsing 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

Research ArticleOpen accessAll words, across the recordEFFECTS OF UV-B ON PHOTOSYNTHETIC PARAMETERS, LIPID PEROXIDATION, FLAVONOIDS AND GROWTH TRAITS OF CONOCARPUS LANCIFOLIUS (ENGL.)Patrice Suleman, Amina Redha, Mohamad Afzal, Redha Al-HasanConocarpus lancifolius is a perennial ornamental plant adapted to the semi-arid conditions of Kuwait. It accumulates most of its biomass during the stressful summer conditions which includes UV-B irradiation. The study evaluated equivalent UV-B irradiation intensities that plants would normally experience sometime during the course of a year in Kuwait. Leaf area, plant height, photosynthetic parameters, Lipid Peroxidation (LP) and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 23 Dec 2013 · 7,548 accessesView PDF Cite
