Single-Cell Transcriptome Sequence Profiling on the Morphogenesis of Secondary Hair Follicles in Ordos Fine-Wool Sheep

International Journal of Molecular Sciences
The Ordos fine-wool sheep is a high-quality breed in China that produces superior natural textiles and raw materials such as wool and lamb meat. However, compared to the Australian Merino sheep, there is still a gap in terms of the wool fiber fineness ...

Reproductive behavior in hair sheep rams under tropical conditions

Tropical Animal Health and Production, 2019
The reproductive efficiency of sheep herds depends to a great extent on the ram. Male reproductive evaluation allows to select for the best and eliminate those with reproductive problems. The objective was to evaluate the effect of breed and age group on the reproductive behavior of hair sheep rams in the tropics of Mexico.

Nitrogen retention in hair sheep lambs with a gradient of Haemonchus contortus infection.

Veterinary parasitology, 2021
The impact of Haemonchus contortus infections on nitrogen retention (NR) of hair sheep lambs is unknown. This study estimated the feed intake, digestibility, NR, haematocrit (HT), and their relationship with the gradient of H. contortus infection in hair

Metabolizable energy balance in hair sheep lambs artificially infected with Haemonchus contortus.

Veterinary parasitology, 2021
In sheep, infection with Haemonchus contortus may increase the need for energy, and this demand may vary according to the infection level. In this study, the energy intake, digestibility, and energy retention of lambs artificially infected with different

Reproductive seasonality in creole hair sheep in the tropic

Tropical Animal Health and Production, 2015
The objective of the present study was to evaluate the annual ovulatory activity of hair sheep at 15° N. Nineteen Creole ewes with body weight of 40.8 ± 0.3 kg were used. The ovulatory activity was monitored for a year by quantifying progesterone concentrations in blood samples obtained from all the ewes every 7 days.

Mineral requirements of hair sheep in tropical climates

Journal of Animal Physiology and Animal Nutrition, 2016
SummaryIn this study, we evaluated the requirements of calcium (Ca), phosphorus (P), magnesium (Mg), sodium (Na) and potassium (K) for sheep hair growth. Experimental diets contained different levels of metabolizable energy [ME; 0.96, 1.28, 1.72, 2.18 and 2.62 Mcal/kg of dry matter, (DM), corresponding to 4.23, 5.64, 7.58, 9.61 and 11.55 MJ/kg DM]. The

Phosphorus kinetics in growing hair sheep

Small Ruminant Research, 2008
Kinetics modelling was used to study the effects of different dietary phosphorus (P) levels on P metabolism in young sheep. An experiment was conducted with 12 Santa Inlambs receiving a basal diet of a hay-concentrate mixture. Different amounts of dicalcium phosphate were added to the basal diet, to give the following treatments levels of 0, 1.5, 3 and

Mitochondrial analysis sheds light on the origin of hair sheep

Animal Genetics, 2012
SummaryA total of 180 mtDNA sequences from hair Caribbean (93), West African (73) and Canarian‐wooled (14) sheep were analysed to shed light on the origin of hair sheep. A comparison of 360 Iberian sheep sequences retrieved from GenBank was performed to assess a possible European origin of the Caribbean hair sheep. These 180 sequences gave 48 different

Chemical Characterization of Melanins in Sheep Wool and Human Hair

Pigment Cell Research, 1996
The color of hair and wool in mammals and feathers in birds is mostly determined by the quantity and quality of melanins that are synthesized in follicular melanocytes and transferred to keratinocytes. There are two chemically distinct types of melanin pigments: the black to brown eumelanins and the yellow to reddish pheomelanins.
