Avermectin-resistance in gastrointestinal nematodes of Boer goats and Dorper sheep in Switzerland [PDF]
Veterinary Parasitology, 2007 Anthelmintic resistance in gastrointestinal nematodes among small ruminants is widespread in South Africa and Dorper sheep and Boer goats have been imported into Switzerland from this country on a number of occasions. Therefore, this study aimed to investigate the occurrence of avermectin (AVM) resistant gastrointestinal nematodes (GIN) in these breeds

Genetic evaluation of growth rate and efficiency-related traits in Dorper sheep
Ecological Genetics and Genomics, 2023 The present study was carried out to estimate genetic and phenotypic parameters for growth rate and efficiency-related traits in Dorper sheep. Growth records from the breeding flock of Dorper sheep collected between 2012 and 2021 at Debre Birhan Agricultural Research Center, Amhara Region, Ethiopia were used in this study.

Effects of grape pomace on growth performance, serum biochemical indices, amino acid composition, and rumen microbial diversity in Dorper × Hu hybrid sheep [PDF]
Frontiers in Veterinary ScienceIntroductionGrape pomace (GP), a byproduct of wine-making, is rich in nutrients and bioactive compounds. However, its effects on the health and rumen microbial diversity of fattening rams remain insufficiently studied.

Genetic parameter estimates for pre-weaning weight traits in Dorper sheep
Small Ruminant Research, 2001 Genetic parameters were estimated for birth-, 42-day, and 100-day (weaning) weight in the Dorper flock of the Glen Agricultural Institute in South Africa. Direct heritability estimates of 0.11, 0.28 and 0.20 and maternal heritability estimates of 0.10, 0.10 and 0.10 were obtained for body weights at birth, 42 and 100 days, respectively.

Comprehensive Analysis of PAPPA2 Expression and Genetic Variants in Sheep and Their Association With Litter Size. [PDF]
Vet Med SciABSTRACT Background The PAPPA2 gene encodes a metalloproteinase critical for regulating insulin‐like growth factor (IGF) bioavailability through cleavage of insulin‐like growth factor‐binding protein 5 (IGFBP5). While its role in human and murine reproduction is documented, its function in sheep reproductive traits remains underexplored. Objective This
