Feeding pigs with proteins from the sea.

Feeding pigs with proteins from the sea.In the search for alternative protein sources, it may be a very good idea to look towards the sea for inspiration. These are the benefits of ingredients like blue mussels, starfish and seaweed. Everybody agrees that it is likely that someday, there will be a shortage of protein to feed livestock in order to fulfil the expected big increase in the demand for meat for human consumption. This issue create a need to search for new sustainable protein sources, which can lead to local or at least European self-sufficiency. As from the beginning of 2018, the organic pig and poultry producers will face a challenge of having sufficient amounts of organic protein. In this context, blue protein, such as blue mussels, starfish, and seaweed may fit well as future feedstuffs, because they solve important challenges for the industry and society. Blue mussels can be grown on lines where the naturally occurring mussel larvae colonise ropes or plastic tubes or nets as of late spring. They filter the seawater for algae and can be harvested year round and already from the first coming winter, preferably before the risk of ice coverage. When mussels are harvested, they need to be processed to allow storage.

Scientist discovers particular seaweed reduces methane to nearly zero in cow burps, farts.

Scientist discovers particular seaweed reduces methane to nearly zero in cow burps, farts. A P.E.I. farmer has helped lead to a researcher's discovery of an unlikely weapon in the battle against global warming: a seaweed that nearly eliminates the destructive methane content of cow burps and farts. Joe Dorgan began feeding his cattle seaweed from nearby beaches more than a decade ago as a way to cut costs on his farm in Seacow Pond. He was so impressed with the improvements he saw in his herd, he decided to turn the seaweed into a product. "There's a mixture of Irish moss, rockweed and kelp, and just going to waste," he said. "And I knew it was good because years ago, our ancestors, that's what they done their business with." The agricultural scientist, then at Dalhousie University, helped test Dorgan's seaweed mix, and discovered it reduced the methane in the cows' burps and farts by about 20 per cent. Kinley knew he was on to something, so he did further testing with 30 to 40 other seaweeds. That led him to a red seaweed Asparagopsis taxiformis he says reduces methane in cows burps and farts to almost nothing.

Feeding dairy cows roughage.

Feeding dairy cows roughage.Before putting together a feeding schedule, confirm the properties of the available feed.Ignorance about feed often results in animals being fed too much or too little, with economic losses. Feed for dairy cows is divided into roughage and concentrate Grazing is normally the cheapest source of roughage for dairy cows. Factors limiting production are mainly energy content and moisture content of crops. The protein content of rye grass clover is usually high. Kikuyu has a low calcium level. Other pastures have high levels of potassium that could increase the incidence of milk fever. The cheapest method of storing roughage. Maize is mainly used, although good quality silage can also be made from most grass types and legumes. The crude protein level in silage is often higher than that of hay. It is excellent for young animals older than nine months. There is no limit to its inclusion in dairy cow rations. Mouldy silage often contains fungi with dangerous toxins and should not be fed to animals.

Advantages of raising pigs.

The advantages of raising pigs. Pigs have fast growth rates and good feed-to-meat conversion ratios; are relatively easy to raise, and do not require much space; have prolific breeding potential; and are docile. These factors not only lead to increased profitability but will surely assist in meeting the growing demand for meat in future. Pork consumption is likely to increase even more due to lower production costs. About 36% of meat eaten by humans annually is pork, followed by poultry (35%), and cattle and buffalo (22%). Lamb and mutton, come in at a distant 4,6%. Many factors affect these trends such as religious beliefs, environmental conditions, pricing and the growth of the human population. Livestock producers continually strive to breed the ‘ultimate animal’ – one that grows faster and converts food to meat better, carries more meat in valuable areas of the carcass, and has a better temperament for ease of handling. It is possible to choose a specific breed or certain outcrosses to satisfy a particular market. For example, very fat pigs may not be useful for the production of belly or ‘streaky’ bacon, as the bacon will have more fat than meat. Pigs usually breed twice a year, and produce about 12 piglets in a litter. These weigh about 1,1kg at birth and, unlike any other livestock, may double their weight in the first week of life if they obtain sufficient milk from the sow. Piglets can be weaned at two to four weeks and can be slaughtered as ‘weaners’ at two to three months old. Other categories include ‘porkers’ (slaughtered at four months), ‘baconers’ (at eight months) and ‘sausage pigs’, elderly animals that are culled.

Basic infrastructure for small-scale pig farming.

The basic infrastructure for small-scale pig farming.The size of your pig housing infrastructure will depend on the number of pigs you have. Ideally, it should be strong, simple and adaptable, and it need not be expensive. The basics needed for a small pig farming operation: design, infrastructure, construction cost, and running costs, including feed, early in the operation. The basic infrastructure depends on how many pigs you want to keep. The design should ideally allow for adding further pens as your operation grows. Previously, I suggested starting off by buying weaners (young pigs already on solid food, usually older than 28 days) and growing them out. In this way, you’ll soon learn about pig behaviour, management techniques and daily feed requirements. Your cash turnover cycle will also be quicker, as you will not need to feed a sow for four months while it is pregnant, manage the birth process, and then feed the piglets until selling them. It is crucial to consider the economics. Is it worth your while to feed the sow for so many months, or should you let another farmer do this for you, leaving you only the task of growing the weaners out to ‘porker’ or ‘baconer’ size?

Radiographs of Dolly's skeleton show no signs of abnormal osteoarthritis.

Radiographs of Dolly's skeleton show no signs of abnormal osteoarthritis. Original concerns that cloning caused early-onset osteoarthritis (OA) in Dolly the sheep are unfounded, say experts at the University of Nottingham and the University of Glasgow. The team, who published last year's Nottingham Dollies research which showed that the 8 year-old Nottingham 'Dollies' had aged normally, have now published a radiographic assessment of the skeletons of Dolly herself, Bonnie (her naturally conceived daughter) and Megan and Morag (the first two animals to be cloned from differentiated cells). Their findings 'Radiographic assessment of the skeletons of Dolly and other clones finds no abnormal osteoarthritis,' have been published in the online journal Scientific Reports. They show that the skeletons, stored in the collections of National Museums Scotland in Edinburgh, bear radiographic OA similar to that observed in naturally conceived sheep and Nottingham's healthy aged clones.

The secret slimming effect of sweet potato waste.

The secret slimming effect of sweet potato waste.The sweet potato pie you eat during the holidays might not be good for your waistline, but according to a new study, the starchy water left over from cooking the sweet potato could have slimming effects . In the new study, mice on a high fat diet had significantly lower body weight after one month if they were also fed sweet potato peptide, which was produced by enzyme digestion of proteins in the water wasted during processing. This suggests the peptide plays a role in digesting fats, but more research is needed to determine whether this also happens in humans. In the new study, Dr. Koji Ishiguro from National Agriculture and Food Research Organization in Japan and colleagues wanted to find a new way to use this waste, so they investigated the effect of proteins found in the water on digestion in mice. "We throw out huge volumes of wastewater that contains sweet potato proteins -- we hypothesized that these could affect body weight, fat tissue and other factors," explained Dr. Ishiguro. "Finding alternative uses for the sweet potato proteins in wastewater could be good for the environment and industry, and also potentially for health."
