Maternal nutrition during pregnancy influences offspring wool production and wool follicle development.
The effects of maternal nutrition on offspring wool production (quality and quantity) were evaluated. Primiparous Rambouillet ewes (n = 84) were randomly allocated to 1 of 6 treatments in a 2 × 3 factorial design. Selenium treatment [adequate Se (ASe, 9.5 μg/kg of BW) vs. high Se (HSe, 81.8 μg/kg of BW)] was initiated at breeding, and maternal nutritional intake [control (CON, 100% of requireme...
متن کاملPerformance of hair breeds and prolific wool breeds of sheep in southern Illinois: wool production and fleece quality.
The objective of this study was to compare weight and quality of fleeces of different F1 ewe types produced from breeds with a broad range of fleece types. Weights of 629 fleeces produced during 1988 through 1991 from F1 ewes that were daughters of Suffolk and Targhee dams and Finnsheep, Combo-6, Booroola Merino, St. Croix, and Barbados sires were recorded. Staple length was measured on the mid...
متن کاملIndigenous Sheep Production in Ethiopia: A Review
Research results and facts of indigenous sheep production were reviewed with the aim of delivering relevant information for the beneficiaries. The common production system used in Ethiopia was the extensive type, which was characterized by small flock sizes and the flock being periodically devastated by diseases. Some indigenous sheep groups of the country were characterized and their names wer...
متن کاملGenome-Wide Association Study for Wool Production Traits in a Chinese Merino Sheep Population
Genome-wide association studies (GWAS) provide a powerful approach for identifying quantitative trait loci without prior knowledge of location or function. To identify loci associated with wool production traits, we performed a genome-wide association study on a total of 765 Chinese Merino sheep (JunKen type) genotyped with 50 K single nucleotide polymorphisms (SNPs). In the present study, five...
متن کاملEvaluation of Crossbreeding Effects for Wool Traits in Sheep
Crossbreeding effects for wool quality traits viz. greasy fleece weight (kg), staple length (cm), average fibre diameter (μ) and medulation percentage were estimated using the Dickerson’s and Kinghorn’s models. The data analyzed involved 15 genetic groups including Nali purebred, F1’s of two and three breeds, F2’s and reciprocal crossbred obtained from the crossing of Nali (N), Merino (M) and C...
