Gut Development and Piglets
During the prenatal, neonatal, and weaning periods, the porcine gastrointestinal tract undergoes several morpho-functional, changes together with substantial modification of the microbial ecosystem. Modifications of the overall structure of the small intestine also occur, as well as a rapid increase of the volume, mainly in the last period of gestation: intestinal villi, starting from jejunum, appears shortly before the sixth week of gestation, and towards the end of the third month, epithelial cells diversify into enterocytes, goblet cells, endocrine, and Paneth cells. Moreover, in the neonatal period, colostrum induces an increase in intestinal weight, absorptive area, and brush border enzyme activities: intestine doubles its weight and increases the length by 30% within three days of birth.

Bovine Respiratory Disease
Bovine Respiratory Disease is considered one of the most common diseases within the Australian beef industry. During the transitioning period of young cattle going into the feedlot system they experience multiple stressors such as environmental changes, dehydration, and fatigue. These stressors negatively impact on the animals’ overall health by markedly increasing physiological stress and decreasing immune response making them more susceptible to diseases, such as bovine respiratory disease complex (BRD).

Macrocyclic Lactone Loss of Efficacy against Dirofilaria immitis
Macrocyclic Lactone Loss of Efficacy against Dirofilaria immitis is a problem of resistance development by D.  immitis (Filarioidea: Onchocercidae), a nematode parasite that inhabits the pulmonary arteries of dogs and other carnivores causing heartworm disease, versus Macrocyclic Lactones, i.e. the drug category used for prevention of heartworm disease.

Practical Use of the (Observer)—Reporter—Interpreter—Manager—Expert ((O)RIME) Framework in Veterinary Clinical Teaching with a Clinical Example
This review explores the practical use of the (Observer)—Reporter—Interpreter—Manager—Expert ((O)RIME) model in the assessment of clinical reasoning skills and for the potential to provide effective feedback that can be used in clinical teaching of veterinary learners. For descriptive purposes, we will use the examples of bovine left displaced abomasum and apparently anestric cow. Bearing in mind that the primary purpose of effective clinical teaching is to prepare graduates for a successful career in clinical practice, all effort should be made to have veterinary learners, at graduation, achieve a minimum of Manager level competency in clinical encounters. Contrastingly, there is relatively scant literature concerning clinical teaching in veterinary medicine. There is even less literature available on strategies and frameworks for assessment that can be utilized in the different settings that the veterinary learners are exposed to during their education.

Colostrum Functional Properties in Puppies and Kittens
Colostrum is the secretion of the mammary gland at the time of the final third of pregnancy. The main source of energy is provided by lipids and carbohydrates. The protein fraction is principally constituted by casein and immunoglobulins, whose role is fundamental for passive immune transfer to newborns.

Atopic Dermatitis in Dogs
Atopic dermatitis is one of the manifestations of atopic disease. In people, dermatitis is typically the first manifestation of atopic disease and can be followed by respiratory disease later in life as part of what is called the “atopic march”. Atopic dermatitis affects people and animals and, in some species (e.g., dogs), is the most prevalent manifestation of atopic disease. Atopic dermatitis in dogs has become increasingly common as exposure to indoor environments and processed foods has increased in our pets. Canine atopic dermatitis has characteristics, both clinically and immunologically, that are strikingly similar to the human counterpart. In dogs, progression to respiratory signs has been described in colonies of atopic dogs, but it does not seem to be a common observation in clinical practice.

Method Used to Control Ticks in South Africa
Ticks are amongst the important ectoparasites where livestock are concerned, as they adversely affect the animals through bloodsucking. In tropical and subtropical countries, they transmit pathogens such as babesiosis, theileriosis, ehrlichiosis, and anaplasmosis in cattle, causing a reduction in production rate and significant concomitant economic losses. Ticks affect 80% of the cattle population across the world, with an estimated economic loss of USD 20–30 billion per year. In South Africa, economic losses in the livestock industry caused by ticks and tick-borne diseases are estimated to exceed USD 33 million per year (ZAR 500 million). There are seven major genera of ixodid ticks in Southern Africa (i.e., Amblyomma, Dermacentor, Haemaphysalis, Hyalomma, Ixodes and Rhipicephalus). The environment in which a tick lives is made up of all the various biological and abiotic factors that are either necessary or unnecessary for its life.

Capripoxvirus Infections in Ruminants
Lumpy skin disease, sheeppox, and goatpox are notifiable diseases of cattle, sheep, and goats, respectively, caused by viruses of the Capripoxvirus genus. They are responsible for both direct and indirect financial losses. These losses arise through animal mortality, morbidity cost of vaccinations, and constraints to animals and animal products’ trade. Control and eradication of capripoxviruses depend on early detection of outbreaks, vector control, strict animal movement, and vaccination which remains the most effective means of control. To date, live attenuated vaccines are widely used; however, conferred protection remains controversial. Many vaccines have been associated with adverse reactions and incomplete protection in sheep, goats, and cattle. Many combination- and recombinant-based vaccines have also been developed.

Vaccines and Methane Emissions from Ruminants
Ruminants produce significant amounts of methane during their digestive process, making livestock one of the largest sources of anthropogenic greenhouse gasses. Several solutions have been proposed to address this problem, including inoculation of ruminants against microorganisms responsible for methane synthesis in the rumen.

Acute Abdomen
Acute abdomen (AA) is the term used to define a pathological condition that affects the abdominal cavity and frequently manifests itself with acute clinical symptoms capable of compromising a cow’s life. Therefore, it should be considered as an emergency that should be evaluated as quickly as possible to adopt the appropriate therapeutic measure (medical or surgical).
