Annotation:

There are no standardized clinical competencies for new graduates interested in small ruminant herd health, medicine and surgery. This void is obvious as other professional veterinary associations publish competency guidelines for new graduates. Small ruminants are becoming increasingly popular with the development of niche markets, low startup cost and increased interest in livestock production for home consumption by owners in suburban areas, which leads to more mixed and small animal practitioners being tasked with seeing small ruminants. A survey was sent to small ruminant practitioners

Diagnostic testing can be a challenging, although very rewarding component of veterinary medicine, which, if carried out with a systematic approach and taking into consideration both history taking/data collection and clinical examination, can enhance the clinician's ability to confidently reach a diagnosis, apply the appropriate changes and/or control measures and, in the end, provide cost-effective benefits to the overall health and management of small ruminants. Many diagnostics tests are available for small ruminants, and the difficulty is to know which are the most appropriate for the dis

Abstract The rumen microbial consortium has long been viewed as a “black box”, where we recognize what goes in, and most of what comes out, but the ruminal catabolic and anabolic activity remains shrouded in uncertainty. Microbiologists from the 1940s through the early 2000s identified microbes responsible for ruminal feedstuff degradation, highlighted animal-important fermentation endproducts (such as volatile fatty acids, VFA), and examined how microbes interacted with each other (e.g., interspecies hydrogen transfer), and with the host animal. However, our knowledge was dependent on our abi

Annotation:

Ruminant and non-ruminant members of the Artiodactyla appear to use different mechanisms for the maternal recognition of pregnancy. In ruminants, the trophoblast of the developing blastocyst produces a characteristic Type I interferon of the interferon-tau family; this acts by blocking endometrial synthesis of the oxytocin receptor. A similar mechanism applies to domestic ruminants (sheep, cow, goat) and deer. In roe deer, which have embryonic diapause and are monoestrus, there is no requirement for a pre-implantation blastocyst signal to ensure maternal recognition of pregnancy. This paper co

Abstract Carbohydrate, derived either from plant cell walls (neutral detergent fiber; NDF) from fresh or conserved forages consumed by cows and growing cattle or from starch of grains and concentrates in commercial feedlot diets, provides most of the dietary energy for ruminant growth and production. The ruminants’ ability to harvest forage from remote, inaccessible locations, to scavenge energy from NDF of feeds and byproducts of grain largely indigestible by non-ruminants, and to employ non-protein N to form protein-rich, nutrient-dense foods for humans are key ecological advantages over non

Background Ruminal methane (CH4) emissions from ruminants not only pollute the environment and exacerbate the greenhouse effect, but also cause animal energy losses and low production efficiency. Consequently, it is necessary to find ways of reducing methane emissions in ruminants. Studies have reported that feed additives such as nitrogen-containing compounds, probiotics, prebiotics, and plant extracts significantly reduce ruminant methane; however, systematic reviews of such studies are lacking.

Abstract The rumen microbial ecosystem provides ruminant animals a selective advantage, the ability to utilize forages, which allows ruminant animals to flourish around the world in a wide variety of environments. The ability of the microbial population to convert sunlight captured in forages to high quality meat, milk, and fiber has been recognized for many years. However, the rumen microbial population composition and degradative activity has remained a “black box” with only the most active (and most amenable to laboratory growth) cellulolytic and hemicellulolytic organisms being recognized

Sheep and goat ownership has been on the increase for several years and shows no signs of slowing down. Many practicing rural veterinarians are often comfortable with cattle, but may be less so with small ruminants. With a foundational knowledge of bovine anatomy, physiology and common disease processes, developing an expertise in small ruminants is possible after learning some key differences. Small ruminant medicine and surgery can be very rewarding and is an important potential growth area for many practices.

In preparing potato chips for the fast food industry a proportion of the material produced is rejected. Although the composition of these partially-fried chips would suggest that the chips should be fed to non-ruminant livestock, the bulky wet nature of the material precludes this option for many. Therefore a substantial proportion of the chips produced are fed to ruminants especially to growing cattle. Little is known about the rumen digestion of such materials. The aim of the experiment was therefore to evaluate potato chips as a ruminant feed.

Annotation:

Fat digestion and metabolism differ widely between animal species. In ruminants, dietary fats are hydrogenated in the rumen before intestinal absorption so that absorbed fatty acids (FA) are more saturated than dietary FA. In non-ruminants, intestinal FA digestibility depends on the level of saturation of dietary FA. Fat supplementation of the diet of cows decreases milk protein and has a variable effect on milk fat, depending on the source of dietary lipids. When encapsulated lipids are used, the linoleic acid content of milk is increased, but the organoleptic quality of milk may be altered.

Abstract This presentation will discuss mineral requirements of ruminal microorganisms, and the effect of trace mineral source on ruminal fermentation. Sulfur and phosphorus are required in relatively large amounts by ruminal microorganisms, and dietary deficiencies of these minerals have been related to impaired ruminal fermentation. A number of trace minerals are required in low concentrations by ruminal microorganisms. With the except of cobalt (Co) minimal trace mineral requirements of the host ruminant appear to be considerably greater than that needed for rumen microbial requirements. It

Dietary recommendations by health authorities have been advising of the importance of diminishing saturated fatty acids (SFA) consumption and replacing them by polyunsaturated fatty acids (PUFA), particularly omega-3. Therefore, there have been efforts to enhance food fatty acid profiles, helping them to meet human nutritional recommendations. Ruminant meat is the major dietary conjugated linoleic acid (CLA) source, but it also contains SFA at relatively high proportions, deriving from ruminal biohydrogenation of PUFA. Additionally, lipid metabolism in ruminants may differ from other species.

As feed evaluation methods for ruminants move towards a more dynamic approach of assessing nutrient supply, in order to reflect the complex nature and microbial intervention in the digestion process in ruminant animals, it is becoming increasingly important to predict the rate, extent and site of digestion. Presently the main method for measuring feed degradation is the in situ polyester bag technique. However, it is now known that this method is not appropriate for starch rich feeds due to the loss of fine particles. An alternative approach is to measure the rumen fermentation kinetics using

Abstract By 1870, we knew plants and animals contained protein, and the participation of protein and urea in animal and human N metabolism was recognized. Nitrogen balance studies had been conducted, and the atomic theory was established. By 1900, research established the concepts of energy and protein metabolic interactions, the role for urea in ruminant metabolism, amino acids as constituents of protein molecules, and enzyme-catalyzed reactions. Research stations were publishing research results and feeding recommendations. By 1950, the concept of biological value was established, and we kne

Although camelids are not taxonomically classified as ruminants, they are functional ruminants. Their digestive system includes a compartmentalised forestomach with a microbial population, and they have apparently evolved the same general characteristics of regurgitation and remastication of food. In vitro digestibility results for camelid diets produced using feeds and rumen liquor from conventional ruminants have been reported. However, the assumption that donor liquor from a true ruminant species is a valid substitute for that from a camelid species has not been verified. The aim of this ex

Fascioliasis is an important zoonotic disease prevalent in domestic animals and it leads to socioeconomic impact in rural farming communities of the developing world. The gold standard diagnosis of ruminant fascioliasis involves coprological detection of Fasciola spp. eggs or recovery of flukes in infected livers. Coprological analysis is unreliable in the patent period of chronic infection, and even then, its sensitivity is relatively low. Robust diagnostic tools that can promptly and accurately detect an active infection are crucial to avoid complications and further losses in ruminant lives

The demand for economic benefits has led to an increase in the proportion of high-concentrate (HC) feed in the ruminant diet, resulting in an increased incidence of subacute ruminal acidosis (SARA). During SARA, a high concentration of lipopolysaccharide (LPS) translocated in the rumen induces a systemic inflammatory response. Inflammatory diseases, such as endometritis and mastitis, are often associated with SARA; however, in sheep, the mechanism of the effect of SARA on the endometrium has rarely been reported. Therefore, the aim of this study was to investigate, for the first time, the infl

Methane production by ruminant animals is an important source of methane to the atmosphere and is considered an important source to more accurately estimate and to control. It has been known for some time that, in ruminants, diet type and composition can influence methane production, yet there is little quantitative information for contemporary diets used in the UK. Attemps to predict methane production from either diet chemical composition or digestibility have not been successful (Moss and Givens. 1990; Johnson et al., 1991). In order to estimate more accurately the amount of methane produce

As a consequence of obvious ethical considerations concerning what is feasible or not in the field of human biomedical research, animal models are of critical importance both for human and veterinary medicine and cognitive scientists. Many species have been and are currently used as animal models. Rodents and lagomorphs are the most popular, essentially because of their low cost, handling and rearing facilities, limited ethical impact, and the availability of a wide range of genetic research tools in these species. Nevertheless, these models present some limitations. The physiological mechanis
