Care of Downer Cows

Dr Phil Poulton from the Tarwin Vet Clinic in Leongatha, Gippsland spoke at a Farmchat day a couple of years ago. Phil has completed a PhD looking at nursing outcomes for Downer Cows. Phil had some key take-home messages to improve outcomes in the nursing of Downer Cows: Act early in the treatment of these animals  Don’t leave them out in the elements – move them correctly into a protected area with soft bedding Give non-steroidal anti-inflammatory early, such as Tolfejec, Key or Meloxicam Ensure they have access to food and water Roll from side to side to relieve pressure on muscle tissue He has found many animals suffer from secondary conditions like mastitis, hypothermia, dehydration & muscle damage which will generally be the cause of death rather than the primary condition. Lifting needs to be done with care - if using a set of hip clamps then a chest strap should also be used and move only short distances. Otherwise, the bucket of a front end loader is ideal.  Warrnambool Veterinary have developed an easy-to-use flow chart for the potential causes of Down Cows along with a Guide on the Care and Management  of Downer Cows.

Dirty Cows – Managing Endometritis in Cattle

OVERVIEW OF ENDOMETRITIS Endometritis is a mild, chronic infection of the uterus. It is very common, affecting up to 40% of post-calving cows. The uterus contains pus and there may be discharge from the vulva. The cows do not seem sick and will still eat, milk and cycle normally. However until the infection clears, they will be unlikely to get pregnant.  Some dirty cows are noticed by farmers if they have vaginal discharge or are obviously smelly. However, many do not show any outward signs. Time and money can be wasted in trying to join cows with underlying infections.  There are other types of uterine infections. Pyometra is another type that occurs when the cervix closes and pus is trapped in the uterus, stopping the cow from cycling. Metritis is a severe infection that can cause sick cows, milk drop, fever and even death. These will be treated differently by the vet.  Reduced general health Cows or heifers in poor body condition Poor nutrition Milk fever Downer cows General stress such as: adverse weather, transport, overcrowding, other diseases Reduced uterine health Twins Difficult birth Uterine tears Dead calf Assisted calving/caesarean Retained foetal membranes Diagnosis of endometritis  It is best to check all cows for endometritis 7-28 days after calving to make sure infections can be cleared up in time for the upcoming mating season. Some farmers prefer to only check the “at-risk” cows or those with obvious vaginal discharge, however this means a lot of cases will be missed.  Diagnosis requires a vet to examine the reproductive tract for pus. A grading system can be used depending on the...

Synchronising – Why, Why Not & How

by Dr Charlie Blackwood WHY SYNCHRONISE HEATS? Synchronising cows can have many advantages including: 1. Easier heat detection Simultaneous display of heat by many cows enables easier detection of cows showing subtle or weak signs of oestrous. Heat detection aids such as scratchies, Kamars and tail paint tend to be more reliable when many cows are showing heat at the same time. NB- some synchrony programs have a fixed time for insemination and do not require heat detection for the first insemination. However, good heat detection after the initial insemination can be a critical factor to achieve overall good herd fertility. Good observation and application of heat detection aids are important for the full duration of the AI period. 2. Earlier detection of non-cycling cows Detection of heat earlier in the AI period allows those cows which are not cycling to be identified and therefore treated earlier. Pre-mating heat detection can also work well for some herds. Regardless, all cows that have not displayed a heat by day 21 into the mating period should be vet-checked. Delaying examination of these animals will be cost more money in the longterm. 3. Tighter calving pattern Breeding more cows over a shorter time frame can help tighten the calving pattern. The earlier cows calve, the more likely they are to get back in calf at the subsequent mating period. An increased number of earlier calving cows also increases milk production early in the season. 4. More heifer calves born early Early-born heifers have the advantage over later-born heifers in that they are more likely to achieve target weights for joining. Having a...

Non-Cycling Cows

The earlier non-cycling cows are treated, the better the return on investment. Economic analysis has shown that it is more profitable to treat non-cycling cows as soon as possible, regardless of your calving pattern.  Reasons for non-cycling cows:  Pregnancy: a surprisingly frequent cause for apparent non-cycling cows. All non-cyclers should be vet-checked prior to any treatment to avoid loss of a potential pregnancy.  Poorly grown heifers: failure to reach target weight at first joining and calving. Onset of puberty is influenced more by body weight than age. Cows in poor body condition: aim to have cows calve at BCS 4.5 (1-8 scale). Reproductive problems: cysts, infections or other issues with the reproductive tract can lead to non-cycling. Other health problems such as lameness, can influence apparent cyclicity. Late calving cows are less likely to cycle in the first month of joining. Speak with your veterinarian about how to effectively manage late-calving cows prior to the start of joining. Cows are cycling but heats were missed. When should non-cycling cows be identified? Prior to the start of mating: using tail paint and pre-mating heat detection. Cows not showing any signs of oestrous should be treated 10 days prior to mating start date. They should then have their first heat at the start of mating. All cows which have not cycled in the first 21 days of mating: these cows should be vet-checked as waiting for these cows to cycle on their own will cost you money.  Treatment for non-cyclers The main treatment for non-cycling cows is the Ovsynch program of which there are various different modifications. Modified Ovsynch Shown to...
