According to the researchers, who came from the University of Nottingham School of Veterinary Medicine and Science, Guide Dogs and Feldon Veterinary Centre, this was the first study to compare peri- and postoperative complications, behaviour after surgery, and surgery duration, for the two most common neutering procedures for female dogs; laparoscopic ovariectomy (LAP-OVE) and open ovariohysterectomy (celiotomy) (OVH-CEL).
For the study, the researchers analysed data from 519 bitches neutered by either LAP-OVE or OVH-CEL at four UK veterinary practices.
Fewer bitches developed wound redness or swelling at the surgical site following LAP-OVE (16%), compared to those that underwent OVH-CEL (36%).
Intraoperative complications were reported for 2% of dogs neutered by LAP-OVE and 3% of those neutered by OVH-CEL.
Postoperative complications were reported for 0.5% of the LAP-OVE group and 1% of the OVH-CEL group.
Unusual behaviours (inappetence, discomfort, licking or chewing) in the postoperative period were less common in dogs neutered by laparoscopic ovariectomy.
There was no significant difference in surgical duration between the two techniques.
The researchers say that their findings add to a growing body of evidence suggesting that postoperative complications, including those related to wound healing and those requiring further veterinary intervention, are lower for laparoscopic than open surgeries for bitches neutered by experienced veterinarians.
Lead author, Dr Rachel Moxon, said: “While there is already evidence from other studies relating to complications following neutering surgeries in bitches, this is the first time that the outcomes have been compared between what are anecdotally reported to be the two most frequently performed neutering surgeries for female dogs in the UK.
"The results will be of interest not only to vets, but for pet owners and others that have to make choices about neutering their dogs. Understanding the surgical risks is an important factor to consider, and decision making is made easier when it can be informed by evidence”.

The study, which was carried out by researchers from the School of Veterinary Medicine and Sciences at the University of Nottingham, is one of the first to look at colostrum hygiene in Great Britain. The researchers analysed data from 328 colostrum samples from 56 British dairy farms.
Samples collected from collection and feeding equipment had higher levels of bacteria than those collected directly from the cows’ teat, suggesting that whilst colostrum from the cow is relatively low in bacterial levels, improperly cleaned equipment can be a major source of bacterial contamination. Over one third of samples collected from collection or feeding equipment were over the threshold for high bacterial levels and represented a significant risk to the health of calves.
Dr Robert Hyde (pictured right), one of the researchers on the study, said: “By analysing colostrum collection protocols on the farms, we were able to identify a small number of management practices likely to have a substantial impact on colostrum hygiene for the majority of farms.
"For example, the use of scalding hot water to clean collection and feeding equipment could reduce bacteria levels by over 90% compared with using cold water only. Less than half of farms used scalding hot water to clean colostrum collection and feeding equipment, suggesting there are a large number of farms that could make this simple change.”
The main recommendations from the research are that colostrum hygiene protocols should include the cleaning of colostrum collection and feeding equipment after every use with hot water as opposed to cold water, and hypochlorite or peracetic acid as opposed to water or parlour wash.
Cows' teats should be prepared with a pre-milking teat disinfectant and wiped with a clean, dry paper towel prior to colostrum collection, and colostrum should be pasteurised where possible.

Robert added: “This study provides a first look at bacteria levels in Great Britain, and the results suggest there are a few simple changes to collection and cleaning protocols that could have a significant impact on colostrum hygiene levels on British dairy farms. By making these simple changes there is likely to be significant improvement in colostrum hygiene, which is essential in minimising the risk of disease and ensuring the optimum health and welfare of calves on dairy farms.”

The study, titled ‘Physics of animal health: On the mechanobiology of hoof growth and form’, represents the fruit of a collaboration between researchers in equine medicine, maths, physics and stem cell biology. It was conducted by the School of Veterinary Medicine and Science at University of Nottingham in collaboration with the Waltham Centre for Pet Nutrition and the Royal Veterinary College.
Lead author Dr Cyril Rauch said: "With new scientific inputs from physics, mathematics and biology, this study provides an entirely new paradigm regarding hard growing tissues such as the horse hoof, which can be applied across cattle, sheep and other species, to unify a set of apparently disparate conditions and clarify the roles of physics and/or biology."
Using hooves from horses euthanased for non-research purposes, the study revealed how it is possible for the hoof growth rate to be greater than the potential proliferation rate of epithelial cells. It also explained how the synthesis of the hoof capsule starts from the coronet and that the soft papillae undergo gradual transition through three interpapillary regions into hard keratinised tissue.
Mathematics, physics and cell biology were then used in the study to explain and describe how the dorsal hoof wall can grow in a curved manner rather than the usual straight manner as a result of faster growth from the coronary band at the quarters compared to the toe region.
Evaluation of the feet from live underweight and obese subjects (assessed using Body Condition Scoring) allowed the influence of body weight on the balances of the stresses affecting hoof growth to be evaluated. The results suggest that being proportionally heavier may promote straighter hoof growth and that being too lean may precipitate poor hoof growth and the development of a hoof with a dorsal curved shape.
The study also showed that a high concentration of insulin stimulated equine progenitor keratinocytes (the outermost layer of cells on the hoof wall) to grow in culture. If this also happens chronically within the live animal, it is possible that it could affect the growth stresses within the hoof and so promote a dorsal curved hoof shape.
Co-author Nicola Menzies-Gow said: "These results taken together can explain how the hoof grows and how it is possible for it to develop a dorsal curvature. However, it should be acknowledged that this does not take into account the genetic or metabolic influences on hoof growth nor the role of hoof trimming and shoeing in maintaining a mechanically healthy hoof. It is appreciated that the underlying biology of hoof growth remains an essential factor for hoof pathologies."
Dr Cyril Rauch continued: “Given that the hoof is a weight bearing element it is essential to untangle the biology from the physics in this system; only then can meaningful biological and/or physical causes be prescribed for particular hoof shape. Removing the cause(s) when physically or biologically possible is essential to resolve hoof conditions."
The students are being given the chance to treat cats, dogs and rabbits coming into the RSPCA centre under the supervision of its resident veterinary surgeon, Joanne Henstock.
The placement offers them valuable skills in dealing with animals which have received little or no veterinary care in the past and often arrive at the shelter in an extremely poor condition.
Ella Carpenter, RSPCA Animal Centre Manager, said: "The students are familiar with seeing pets which have been well cared for by their owners and it can be shocking for them to witness the state in which some of the animals arrive at our shelter.
"In particular, they see the, often life-threatening, impact it can have on an animal when it hasn’t received care considered to be fundamental veterinary medicine, such as flea or worming treatments.
"We commonly see animals that arrive with little or no medical history, so they can practice a back to basics, 'treat what we see', approach. And they learn about the challenges we face in providing the best possible care for large numbers of animals, many with complex medical needs, while working within the finite resources of a charity which relies entirely on public donations."
Malcolm Cobb, Professor of Comparative Veterinary Medicine and Deputy Head of the School of Veterinary Medicine and Science, said: "We are really excited to be working with the RSPCA at Radcliffe. There is a very large and varied case load for our students to assist with, learn from and help to manage, including some cases of neglect which they might not see elsewhere, and which can represent a significant clinical challenge."

The Sutton Bonington Campus, home of the University of Nottingham's School of Veterinary Medicine and Science, has raised £610 for Sport Relief with its annual Science Cake Competition.
There were thirty entries to the competition, in categories which included Animals & Agriculture, Food & Nutrition, Infection, 'Nerdy' Science, Plants, Crops & Environment, and Veterinary Medicine.
A special category this year was 'Cakes for Animals', which Emily Blight, an undergraduate vet student, organised for a panel of dogs to judge on tastiness.
The winner of the public vote was 'What came first, the chicken or the cake?' (pictured right), whilst the overall winner was Alex Burgess with ‘Dave’s Allotment’.
One of the judges, Dr Mike Jones said: "Choosing the winner was extremely hard. Every cake had its own specific merits be it the execution of the design, through to the novelty of ingredients and ideas or how they fitted into the categories." He added that he "was almost put off jelly beans for life - they will be forever associated with sheep back sides."
The cakes are all on display here.
Seven graduands from The University of Nottingham's School of Veterinary Medicine and Science have become the first from the new school to become members of the Royal College of Veterinary Surgeons.
Nottingham is the first new veterinary school in the UK for over 50 years, and the process to recognise its degree for the purposes of RCVS membership is currently in its final stages. Following a visitation and audit process, RCVS Council unanimously recommended the degree's approval to the Privy Council, where the final decision lies.
Generally, veterinary graduates become RCVS members - which they need to be in order to practise in the UK - at a ceremony on the day of their graduation. However, sometimes they wish to start work before graduation and can therefore apply to register as graduands, as in this case.
Although formal Privy Council approval of the Nottingham degree is still awaited, RCVS external examiners have overseen the School's final exams during the last year of the course to ensure that they meet the required standards.
The Nottingham graduation ceremony will take place on 22 July, when a further 77 students will graduate, and those wishing to practise in the UK will become members of the College.
The RCVS 2010 Survey of the Veterinary and Veterinary Nursing Professions indicated that, on average, new graduates took one month to find work on graduating, with 63% going straight into clinical practice.
