Aim of study: To evaluate the physicochemical and sensory quality meat from Santa Inês × Dorper lambs fed diets with increasing levels sunflower cake.
 Area Rio Grande do Norte (Brazil).
 Material methods: Twenty-four castrated (initial weight 18.9 ± 2.17 kg) were distributed in a completely randomized design four treatments (0, 5, 10 15% cake diet) six repetitions kept confinement un...

Hyalomma ticks were collected from Merino and black-headed Dorper sheep and their attachment preferences determined. The preferred site of attachment for Hyalomma marginatum rufipes on both Dorper and Merino sheep was the anogenital and inguinal areas (75-76%). On Dorper sheep, H. truncatum attached predominantly to the anogenital and inguinal areas (67.7%). On Merino sheep, most adults of this...

ICAR Technical Series No 3 The development of the Dorper sheep and the Improved Boer Goat are undoubtedly two of the most successful long-term livestock programmes in South Africa. The Dorper is a composite mutton sheep breed developed through crossing an indigenous breed with a British mutton breed and the Improved Boer Goat was developed using a breeding strategy based largely on selection fo...

The Dorper is a hardy South African composite breed, derived from a cross between the Black-headed Persian and the Dorset Horn. Dorpers are regarded as early-maturing, and ewes lambed at an age of 1 year in one study. Age at first lambing was higher in other literature sources cited. The fertility of Dorper ewes was approximately 0.90 ewes that lambed per ewe mated, with a litter size ranging f...

This study evaluated the reproductive and productivity of local Dorper crossbred ewes in a community-based management system. We analyzed data collected from 2013 to 2021, taking into account different factors such as dam-breed, location, type birth, season, year lambing. Lambing was observed all year-round, but majority (35%) occurred September, October, December. suggests that pasture availab...

The objective of this study was to evaluate the frequency of C242T polymorphism on the aromatase gene and the allelic and genotypic frequency of these variants in sheep belonging to four breed groups. Blood samples were collected from 187 animals of four breed groups: Dorper, Santa Inês, Texel and White Dorper, originated from herds in the region of Maringá/PR, Brazil. The genomic DNA was extra...
