... China has the world's largest sheep flock and the largest producer of sheep meat by far. However, the nutrient requirements have not been systemically studied and there is a lack of knowledge of nutrient requirement for meat-type sheep in China. Since 2008, the nutrient requirements of meat-type sheep in China has been systematically investigated. In this review, we introduced the history of studi ...

Abstract:
... BACKGROUND: Sheep scab is considered an endemic disease of great welfare and economic significance in the UK. METHOD: This paper provides an up‐to‐date assessment of the impact of Sheep Scab (Scotland) Order 2010 on sheep scab notifications in Scotland between 1 January 2014 and 31 December 2019, using data collected by the APHA. RESULTS: In total, 564 sheep scab notifications were reported from 5 ...

Abstract:
... Infection caused by gastrointestinal nematodes is an important issue for animal health and production. Controlling worm infections improves the sustainability of the sheep industry. Genetic selection of animals that are resistant to gastrointestinal nematodes is another strategy to render sheep production more sustainable by decreasing the use of anthelmintics. The aims of this study were (1) to e ...
... The objective of this study was to define coping style of sheep by using unsupervised machine learning approaches. A total of 105 Norduz sheep (age 3–5 years) were subjected to a 5-minute arena test. Agglomerative Hierarchical Clustering (HCA) was performed on scores of selected principal components retained from Principal Components Analysis (PCA) on arena behaviors to identify sheep coping style ...

Abstract:
... This study analyzed the genetic variability, inbreeding and population structure of the Tunisian–North African dairy sheep breed, the Sicilo-Sarde (SS), created by crossing the Sarda and Comisana dairy breeds. The level of variability in the SS, considered as an endangered breed after a dramatic decrease, was assessed using 17 microsatellite markers by analyzing the two breed populations sampled f ...
... Osteomyelitis is an infection of the bone characterized by progressive inflammatory destruction and apposition of new bone that can spread via the hematogenous route (hematogenous osteomyelitis (HO)), contiguous spread (contiguous osteomyelitis (CO)), and direct inoculation (osteomyelitis associated with peripheral vascular insufficiency (PVI)). Given the significant financial burden posed by oste ...
... Since the reintroduction of sheep scab within the UK, its prevalence has increased despite several industry-led initiatives to control and manage the disease. Some studies have suggested that initiatives or policies should instead focus on specific places, such as geographically high-risk areas for sheep scab, which could allow for a more targeted approach. However, this risk of sheep scab has bee ...

... Lamb production in Brazil has the state of São Paulo as its largest consumer market, but due to competition for area with other agricultural activities, sheep farming in São Paulo underwent an intensification of the production system to achieve better economic profitability. This intensification can compromise the sustainability of the system. There is no research concerning about emergy evaluatio ...

Abstract:
... Hair follicle development in Tan sheep differs significantly between the birth and Er-mao periods, but the underlying molecular mechanism is still unclear. We profiled the skin transcriptomes of Tan sheep in the birth and Er-mao periods via RNA-seq technology. The Tan sheep examined consisted of three sheep in the birth period and three sheep in the Er-mao period. A total of 364 differentially exp ...
... Brazilian goat and sheep farming has increased their activities in the past years, with an increase of the number of flocks, of farms with sheep and goats, of animals and volume of dairy products sold. We observed an improvement of the professionalization of the activity, with added - value products and the creation of cooperatives and other collective initiatives; farmers improved their hygienic ...
... Eurytrematosis is a disease caused by flukes of the genus Eurytrema. These parasites infect the pancreatic ducts of a wide variety of species, including cattle, sheep and humans. Diagnosing eurytrematosis through the analysis of faecal samples can be difficult because most of the available techniques are considered of low sensitivity. In this context, a modification of the Dennis, Stone and Swanso ...
... The aims of this study were to analyze the effects of PPARGC1B and ZEB2 polymorphisms on the body weight of Hu sheep. DNA sequencing and KASPar technologies were used to detect single nucleotide polymorphisms (SNPs) within the PPARGC1B and ZEB2 genes of Hu sheep (n = 207). Two synonymous mutations, g.300 G > A and g.645 C > T, were detected in PPARGC1B and ZEB2, respectively. The body weights of s ...

Abstract:
... Accurate and reliable on-farm protocols are essential in sheep welfare evaluation. However, protocols with a high number of measures are demanding in terms of time. The aim of this trial was to use a few already validated, reliable, feasible, rapid and non-invasive animal-based indicators to evaluate and compare welfare on dairy and mixed purpose sheep farms. Indicators included prevalence of lean ...
... Flystrike remains a serious financial and animal welfare issue for the sheep industry in Australia despite many years of research into control methods. The present paper provides an extensive review of past research on flystrike, and highlights areas that hold promise for providing long‐term control options. We describe areas where the application of modern scientific advances may provide increase ...

... Sheep scab, or psoroptic mange, a disease caused by the mite Psoroptes ovis, is commonly treated with ivermectin (IVM) and other macrocyclic lactones. In Argentina, in vivo trials have shown a decrease in IVM effectiveness to treat both sheep and bovine scab. In this work, we used an in vitro technique to establish the efficacy of IVM and two other macrocyclic lactones, doramectin (DRM) and moxide ...

Domestic cat oocytes were matured in vitro (IVM), fertilized (IVF), and cultured individually or in groups in drops under oil (20 μL or 50 μL) and in 16 microwell dishes (Primo Vision®). Moreover, the effects of co-culture with a) uncleaved oocytes, b) homospecific and c) heterospecific co-culture with cat and sheep comp ...
... The dairy sheep industry is an important but lacking part of the small ruminant industry. For a sheep breeding program, in addition to wool and meat use, sheep milk can also be processed into high-end dairy products such as cheese and milk powder and bring high economic interests for businesses home and abroad. With increasing interest in sheep milk, the content of which is becoming increasingly c ...
