ANIMAL HEALTH 20 The North Canterbury News, September 16, 2021 ADVERTISING FEATURE Nutrition in early lactation During earlylactation,dairy cows experience arapid increaseinmilk yield,coupled with alow DMI. Duetothis inevitable imbalance, dairy cows enterastate of negative energy balance (NEB),resulting in body fatmobilization. An increase in the circulating concentrations of nonesterified fatty acids(NEFA) in the weeks following calving is part of normal adaptationfrom thecows. Thus, eventhough NEB cannot be prevented, severity and duration of NEBshould be reduced, because excessconcentrations of NEFAs are detrimentaltomilk production, reproductive outcomes,animal health,and immunesystemfunction. In apasturebased system like we have here in New Zealand this lower DMI, togetherwithvery high levels of protein in the diet,(Westwood et al., 2000) and exposure to undesirable weather conditions in earlylactation mayextend the periodofNEB. Theuse of some simple feeding strategiestohelp balance the diet with enougheffective fibre, like using adlib straw in the paddock,as well as higherallowance of glucogenic nutrientslike feeding grain, will help the cows go back to positive energy balance fasterand effectively. Calving and early lactation are a stressful period for the dairy cow. Researchhas shownthat at the molecular level,nutritional, technological, environmental and internal stresses lead to the overproduction of free radicals. Theaccumulation of these free radicalsproduces what is called oxidative stress. This oxidative stress has several detrimentalconsequences affecting immuneand reproductive systems, as wellasgeneral health. In dairy cows, oxidative stressis also showntobeassociated with the retention of foetal membranes postcalving, as well as disrupting folliculogenesis(reproductive eggs formation), oocyte maturation, ovulation, formationofblastocysts, implantation,luteolysis and luteal maintenanceinpregnancy. Allstressfactors contributing to oxidative stress can potentially decrease productive and reproductive performance and compromise animalhealth. Thegraphiconthe rightisagood graphic example to show the damage caused by oxidative stress. Under stress ... Oxidative stress has several detrimental consequences affecting immune and reproductive systems, as well as general health in dairy cows. IMAGE: SUPPLIED This is whatcan happen to any cell in the cow includingthe oocyte (cow’s egg) in the ovary resulting in poor conception rates and poor fertilityoutcomes. Selenium (Se)isinvolved in all antioxidant defence mechanismsin the cow. Meeting Se requirements is crucial to avoid oxidative stress. SelPlex® fromAlltech® Inc., is a proprietary organic form of seleniumyeast manufactured to mimicselenium which is naturally present in plants and found in nature. SelPlexishighlydigestible,better absorbed, storedand utilized by the animal whencompared with other sources andforms of selenium. Bioplex® High Fivecontains not only SelPlex, but also copper(Cu), zinc (Zn), cobalt(Co) and iodine(I), all in organic form, which hasbeen proven to have betterbioavailability resulting on improved natural immunity and defensive mechanisms for the cow to overcome diseaseand metabolic issues. Alltech’s range of organicproducts are designed to improve the immune system of cows,helpingthem battle disease and reduce the duration and severityofthe NEB period after calving.

Check-ups essential By SHELLEY TOPP Annual healthchecks are essential for pets, because ‘‘ourcanineand feline friends’’ age alot fasterthan us, aRangioraveterinarian says. ‘‘Oneyear withouta checkup is likeusnot seeing the doctor for 57 years,’’ Samantha Allott, who works at the VetEnt Rangiora West veterinary clinic, says. ‘‘When we are with our pets every day we may not notice or acknowledge small changes in them and they are not able to tellushow they feel. ‘‘Vets are trained to examine animals and identifywhen something is not normal.’’ Regularhealth checks also allow earlier detection of conditions such as kidney disease or diabetes,which oftenresults in abetter outcome for the animal. ‘‘When apatient presents very sick, it is often more difficultand expensive to treatwith aless favourable prognosis,’’ Samantha says. An annualhealth check begins with aconversation between the veterinarian and pet owner to determine what foodthe pet eats,how much it drinks, how much exercise it gets, what its energy levelsare likeand if the owner has any concerns aboutthe animal’s health. Afterthat the animalwill Delicate job ...

The vetwill also gently palpate the pet's abdomen to check that its organs feel anormalsize,there are no odd lumps, bumps or free fluid and there is no painor discomfort. The animal's joints will also be checked for any signs of arthritic pain or reduced mobility and any flea/worm or vaccinations that may be due will be administered. Ablood test may also be done at this time to check the animal's organs are functioning properly. Health checksshould begin as soonasthe animal becomespartofthe family, with puppy and kitten checkups from 68 weeks of age, Samantha says.

ANIMAL HEALTH The North Canterbury News, September 16, 2021 21 Local vet supports horse gel studies By SHELLEY TOPP ANorth Canterburyveterinarianis working withaUniversity of Canterbury academic to develop a woundhealinggel forhorses. Thegel,which is abreakthrough discovery in tissue regeneration, was developedfor humans by an internationalpartnershipled by ProfessorRudi Marquez,who is head of theuniversity’s School of Physical andChemical Sciences andadirector andcofounderofTissue Repair Technologies (TRT), acompany which originated from the University of DundeeinScotland. ProfessorMarquez worked with two otheracademics, Dr AnaSchor and Dr DavidNorman,todevelopthe gel, whichisasmallmolecule pharmaceuticalthatkickstarts healinginwoundsthatfail to heal quickly or properly. ‘‘The TRT treatment, applied to a woundasagel, hasbeen shown to accelerate healing of aslowhealing leg woundand appears to regulate the overgrowth of tissue,’’ Professor Marquez says. ‘‘The molecule in the gel could be particularlyusefulinthe treatment of diabetics withfoot ulcers.’’ Nonhealing(chronic) skinulcers arealso acommon occurrencein elderly patients. Althoughthe gel was initially formulatedfor human patients, TRT hasrecently extended its woundhealingstudies to include horses. Thecompany is workingwithLoburn veterinarian Becky Sutorius,of Rangiora Equine Services, to trial the effectiveness of the gel. Becky Sutorius ‘‘Horsesare alot like diabetic human patientsinthat if theyget an injuryatthe bottom of theirleg,it doesn't heal verywell,’’ Professor Marquezsays. ‘‘When they do heal, the process can lead to an overgrowth of tissue causing further problems. ‘‘So extending ourstudy to horses offersusthe chance to make a significantcontributiontothe New Zealand horseindustry and at the sametimecontinue the development of human treatments.’’ Becky saysthe overgrowth of tissue prevents wounds fromhealing, which increasesthe riskofbleedingand infectionand alsoincreases theriskof tumourformation. She began workingwithProfessor Marquez on theprojecttwo years ago and says theresults of her trial so far are ‘‘promising’’ in terms of reduced scartissue, faster healing, less downtime fromcompetition,improved welfare and lessstress on thehorses, Tissue repair ... Agel developed for humans could speed up the healing process for horse wounds. PHOTOS: FILE as well as reduced costs to the owners. Professor Marquez says theproduct is in theadvanceddevelopment stages, but still some wayfrom being approved for sale. ‘‘Wewould like to carry out alarger trial, andthentoapplyfor registration,’’hesays. ‘‘Weexpect this to take place in the next612 months. ‘‘Atthe moment, we areexploring the possibility of using it in New Zealandinasimilarway as the cascade processinthe United Kingdom,whereby experimental drugs can be administered by a veterinarian on anoncommercial basis.’’ Twosimilarproductswill be developed, onefor humansand one for horses. ‘‘Thedosage will havetobe optimised, and will requirefurther regulatoryapproval,’’Professor Marquez says. ‘‘We want to make sure that we have aproduct that is effective andeasily affordable, althoughweare acompany, our main drive is to improvehumanand animal health. ‘‘Ideally,wewould liketobeableto produceitand manufacture it locally in Canterbury’’’ IT’S ABOUT TIME SOMEONE STARTED THINKING LIKE AFARMER.
