Reasons for general treatment with antibiotics
The most common reason for treatment of cattle and sheep is mastitis (udder inflammation). For horses, lesions and other injuries are the most common reasons for treatment with antibiotics, while pigs are treated for lameness and other symptoms occurring in joints and hooves.
Calf mortality among different breeds of cattle
The table is organised after sex and breed and shows the number of calves that die within a month after birth. Mortality is generally somewhat higher for bull-calves than for cow-calves.
Frequency of disease in dairy herds of various sizes
Comparisons between different herd sizes have been made regarding the occurrence of a number of diseases. Milk fever and ketosis decrease with increasing herd size, while mastitis and other diseases increase. A relationship might be suspected between those diseases showing an increase within larger herds and an increase in infection pressure due to many animals being held in the same building. The diseases showing the most apparent decrease in large herds are feeding related. One can assume that a larger number of technological solutions are available for optimization and control of feeding in larger herds.
A few diseases show small variation between the different herd sizes, these are: retention of afterbirth, teat injuries and delivery problems.
Frequency of disease in dairy herds from different breeds
Swedish Friesian have the largest number of diseases compared to other breeds.
Occurrence of colic in horses - seasonal variations
A monthly comparison of colic cases has been compiled for the three regions in Sweden: Götaland (south of Sweden), Svealand (middle) and Norrland (north). The extent of colic cases is markedly low during the summer months. The diagnoses included in the term colic are impaction colic (constipation), incarceration colic, displacement colic, abdominal pain as well as all other diagnoses that include the term "colic."
These statistics are primarily based on veterinary reports submitted to the Swedish Board of Agriculture. The national industry organisation Svensk Mjölk (Swedish Dairy Association) has compiled the data for "Frequency of disease in dairy herds of various sizes," while information for "Calf mortality among different breeds of cattle" was collected from the central animal database where every cattle owner reports animal transports, births and deaths.
