“…Indeed, results vary depending on country, use of horses (leisure, competition) and season. Moreover, it has also been shown that horse owners consistently underestimate the body condition of their horses [ 12 , 14 , 17 , 21 , 23 , 24 , 27 , 28 ].…”

IntroductionObesity is a growing concern in horses. The effects of maternal obesity on maternal metabolism and low-grade inflammation during pregnancy, as well as offspring growth, metabolism, low-grade inflammation, testicular maturation and osteochondrotic lesions until 18 months of age were investigated.Material and methodsTwenty-four mares were used and separated into two groups at insemination according to body condition score (BCS): Normal (N, n = 10, BCS ≤4) and Obese (O, n = 14, BCS ≥4.25). BCS and plasma glucose, insulin, triglyceride, urea, non-esterified fatty acid, serum amyloid A (SAA), leptin and adiponectin concentrations were monitored throughout gestation. At 300 days of gestation, a Frequently Sampled Intravenous Glucose Tolerance Test (FSIGT) was performed. After parturition, foals’ weight and size were monitored until 18 months of age with plasma SAA, leptin, adiponectin, triiodothyronine (T3), thyroxine (T4) and cortisol concentrations measured at regular intervals. At 6, 12 and 18 months of age, FSIGT and osteoarticular examinations were performed. Males were gelded at one year and expression of genes involved in testicular maturation analysed by RT-qPCR.ResultsThroughout the experiment, maternal BCS was higher in O versus N mares. During gestation, plasma urea and adiponectin were decreased and SAA and leptin increased in O versus N mares. O mares were also more insulin resistant than N mares with a higher glucose effectiveness. Postnatally, there was no difference in offspring growth between groups. Nevertheless, plasma SAA concentrations were increased in O versus N foals until 6 months, with O foals being consistently more insulin resistant with a higher glucose effectiveness. At 12 months of age, O foals were significantly more affected by osteochondrosis than N foals. All other parameters were not different between groups.ConclusionIn conclusion, maternal obesity altered metabolism and increased low-grade inflammation in both dams and foals. The risk of developing osteochondrosis at 12 months of age was also higher in foals born to obese dams.

“…The third area comprises Bang's work on tuberculin and its application for diagnosing and combatting tuberculosis in cattle by means of a method developed by himself [35]. Bovine tuberculosis was causing 25% of intestinal and glandular tuberculosis in the Danish population due to the presence of the bovine mycobacteria in the milk [30,35,36]. Bang became world famous and after his retirement got a lifelong annual gift from the Danish state.…”

Høiby N. Louis Pasteur and the birth of microbiology in Denmark. APMIS 2022. Louis Pasteur's work initiated the birth of microbiology in Denmark. Carl Julius Salomonsen was the pioneer who inspired and taught Christian Gram, Thorvald Madsen and Bernhard Bang bacteriological techniques in his annual bacteriological course which he started in 1883 at the University of Copenhagen. These pioneers developed Danish human and veterinary microbiology and became world famous. Emil Chr. Hansen developed Danish technical/industrial microbiology in the Carlsberg Laboratory and purified yeast and designed equipment for the propagation of pure yeast which was used worldwide in beer brewing. He also became world famous. The fascinating birth and development of Danish microbiology is summarized in this article, which is dedicated to the 200th birthday of Louis Pasteur, December 27, and 100th birthday of the Danish Pasteur Society, October 25, 2022.

“…The average energy content of forages analysed for horses in Iceland over the last 4 years (2020-2023) was 0.73 Fu (ranging from 0.55-0.87, unpublished data, Efnagreining.is, 2024; personal communication). Overfeeding seems to be increasing the problems for riding horses and is of grave concern, as recent studies [21,22] have shown that obesity is becoming a major welfare issue [23], not least in ridden leisure horses and ponies. Therefore, it is important to find ways to extend the feed intake time of stabled Icelandic riding horses when fed high-energy forages in smaller amounts, often resulting in a lower dry matter intake than recommended [9].…”

The natural behaviour of horses is to spend the majority of their time on feed intake The feeding of stabled horses is, however, often far from that, as their feed intake is limited to their nutritional requirements. In order to approach their natural foraging time, it is important to extend the feed intake time of stabled horses. The aim of this study was to estimate if the feed intake time differs when feeding haylage in a haynet, hayball, metal corner manger, or from the box floor. The experimental design consisted of a Latin square, occurred across four days with four adult Icelandic horses and four treatments. Horses were stabled in individual boxes and fed 7 kg of high-energy haylage in two even meals while the intake time was recorded. The feed intake time per kg DM was shorter from the manger or the box floor than from a haynet or hayball (81 or 85 min versus 94 or 96 min; p < 0.05). It can be concluded that feeding haylage in a hayball or in a haynet can increase the feed intake time by 13% per day (12 min/kg DM/day) when compared to the more traditional methods. Thus, with simple alternatives, it is possible to extend the feed intake time of stabled horses.
