During gestation sows are loose housed in groups and fed using electronic sow feeders.
success. Actions must be taken and attention to detail can make the difference. Recently cameras were installed in the farrowing shed. Recordings from these are used to keep an eye on the animals and to educate staff. The recordings provide Brosnan with information and allows for information based decisions rather than guessing. The purpose of the cameras is also to provide more knowledge to the outside world and to share experiences with scientists and industry people to create a win-win situation.
Focused on routines It is no secret that one of the challenges with free farrowing is bringing down piglet mortality. At Bettapork pre-weaning loss- es are currently fluctuating around 14-20% where peaks are caused by outbreaks of diarrhoea, but the aim is to bring mor- tality down to 10%. A key feature of this SWAP farrowing sys- tem is the opportunity to use a simple form of confinement for a few days after farrowing where the piglets need protection. However, even though Brosnan has the option to confine the farrowing sows, he has decided to keep the sows loose at all times. Loose farrowing sows are challenging for people who have worked with pigs their whole lives. Yet, at Bettapork, this is even more the case, since a lot of staff are backpackers seek- ing work for a few months at a time without any previous experience with pigs or farming. Simple and strict routines, and proper training is even more important. Brosnan explains, “Strict procedures are in place from the simplest of tasks to the more complex tasks. Of course the more complex duties are performed by our skilled stockpersons. In addition, where pos- sible, we have automated duties that would normally be per- formed by stockpersons.” Brosnan uses backpackers because it is hard to find qualified employees – just like in a lot of other more remote places in Australia. An advantage of backpackers, though, is that it is easier to have nightshifts and constant surveillance of sows and piglets. At Bettapork, employees are present in the farrowing shed 24/7 throughout the week and they are carefully instruct- ed on how they should handle the newborn piglets. The major- ity of piglet mortality occurs around farrowing and in the first days thereafter, so in order to keep mortality down, a lot of

time and effort goes into this period. When asked what is the most important management tool, Brosnan says, “Supervision, supervision, supervision!! If a stockperson is around for the first two to four days after farrowing, then you can really reduce piglet losses.” Every week approximately 65 sows give birth to an average of 12 live born piglets. Functional teats are counted and noted on the sow card so everyone knows how many piglets the sow can foster. At birth the piglets are dried with drying powder. This is important because it helps the piglets but also because it helps keep the pen dry in general. Split suckling is standard proce- dure to make sure that small piglets also get a space at the udder and some milk. Turnover of staff and the workers’ limited experience with pig farming makes training and correct instruction key to achiev- ing good results in the farrowing unit. Good stockmanship is often associated with lots of experience and a trained eye that sees things that others don’t. However, a systematic approach, proper training and follow-up is also an important part of good stockmanship – Bettapork is a very good example of this. Here, the guidelines are strict and the emphasis is on carrying out procedures systematically and correct. If mistakes are made, actions are taken to correct it and to make sure they don’t happen again. It is important to Brosnan that workers understand what their job is and how to do their best even though they are jumping in at the deep end. A lot of time and energy is therefore spent on instruction and training of staff but efforts are repaid in good production results and a modern, high performing site that keeps moving forward.
Breeding a sow to suit the environment All the efforts that have been put into the free farrowing sows and the learning experiences that have come from it will benefit the new breeder site when they start up with free far- rowing. In addition, research has documented a relationship between genetics and environment meaning that using the same system for breeder sows as well as production sows is beneficial. So today, Brosnan and his family are in the process of building a new farrowing shed for their nucleus site – also with loose housing.
