If you follow my blog or my face-book page you already know what GMOs are, but here is the basic definition -Genetically modified foods (GM foods, or bio-tech foods) are foods derived from genetically modified organisms (GMOs), such as genetically modified crops or genetically modified fish. GMOs have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise than mutation breeding where an organism is exposed to radiation or chemicals to create a non-specific but stable change. The scientist at Monsanto started inserting genes from bacteria and viruses into crops. That’s were they got a crop that could either survive a application of the company’s herbicide glyphosate (roundup) or produce its own insect killing pesticide. Coming soon the USDA will be approving Agent Orange resistant crops (this have been proven in studies after Vietnam to cause cancer and birth defects).
Research has shown lower levels of nutrients in crops sprayed with Roundup. These crops are specifically engineered to tolerate the herbicide Roundup, whose use has increased with the release of Roundup-Ready GM crops. Glyphosate, the active ingredient in Roundup, decreases nutrient availability and uptake in plants. Some of these nutrients help plants and animals fight disease. Recent studies have shown a link between high rates of spontaneous abortions and infertility in livestock fed GM Roundup-Ready crops.
We know very little about the effects of genetically modified organisms on livestock and human health. Researchers in Italy have performed a study on some of the effects, and their results were released last year. They fed one group of pregnant goats rations with non-GM soybean meal and another group with GM Round up sprayed soybean meal. The mothers received this diet for two months prior to the birth of their kids. Then the offspring were fed milk only from their mother for 60 days. The results showed DNA from the GM Roundup-Ready soy in the blood, organs, and milk of goats. Also, the kids of the mothers fed GM soy had substantially higher levels of an enzyme, lactate dehydrogenase (LDH), in the heart, muscles, and kidneys. Similar metabolic changes have been found in studies of GM-fed rabbits and mice, as well.
The word is spreading that rabbits fed pellets from company’s that use GMO grown products in the manufacturing of their pellets are getting sicker. Laboratory GMO fed rabbits have had organ damage, reproductive failure, high death of kits, stomach legions, smaller bodies and organs, low immune responses, and higher death rates. There is no actual facts that I have, just resource’s and articles I have found.
The way a rabbits digestive system works is that the beneficial bacteria that needed in the gut must flourish and adapt to their food source. If this bacteria is off it will cause all kinds of digestive problems such as enteritis, bloating, wasting away and more! If the bad bacteria starts flourishing this can cause coccidiosis and other problems. Last year I have had a rash of emails, phone calls, people stopping by the rabbitry to ask questions about problems with their rabbits. The only common factor in all these cases is the use of GMO pellets. Not just in one area (from California to Maine) or season (Spring to winter)! I do not believe that they are stress related. I am lucky to feed the lowest amount of pellets I have too, to keep my rabbits productive and healthy. By feeding rabbits a more natural diet and keeping a closed herd, has been the best thing for me and my rabbits.
A result in tests done on rabbits fed gmo soy-meal was released found Roundup Ready Soy Changed Cell Metabolism in Rabbit Organs, Rabbits fed GM soy for about 40 days showed significant differences in the amounts of certain enzymes in their kidneys, hearts and livers. A rise in LDH1 levels in all three organs suggests an increase in cellular metabolism. Changes in other enzymes point to other alterations in the organs. When cells are damaged in mammals, LDH levels are elevated. It is a key indicator of cancer, and LDH remains elevated after a heart attack. Increased LDH is associated with several other health disorders
A German farmer who had 65 cows die after he fed them genetically modified Bt corn has filed criminal charges against Syngenta, alleging that the company knew the corn could be lethal to livestock, and covered up deaths that occurred during one of their clinical feeding trials. Swiss bio-tech Syngenta committed a grave criminal offense by deliberately withholding the results of a feeding trial in which four cows died in two days. The deaths prompted the company to halt the test. No health problems or deaths were reported in the control group, which was not fed the genetically engineered Bt 176 corn.
Thousands of livestock deaths have also been reported across India, as a result of grazing on genetically engineered crops and feed.
Alfalfa is the number one forage crop in the United States. In January 2011 the USDA approved the release of genetically modified (GM) alfalfa, raising the prospect that some non-GM alfalfa will be contaminated by GM alfalfa by cross-pollination from bees (could this also be the health problem bees are having?). Soon the first cuttings of GM alfalfa will be harvested and fed to livestock and be in your rabbit pellets with the GMO soy products. I have been called a conspiracy theorists but is this a way to control the food supply. You will not be able to raise any animals without the use of GMOs. This is why I push the Natural diet for us and our rabbits! Please comment your thoughts and ideas!
With summer heat on the way , raising rabbits can be very frustrating. Every year you hear of rabbit deaths due to heat. Many days in the summer there are temperatures approaching 80ºF to 95ºF+. For rabbits outside in a hutch (even in a shady area) this can be a death sentence. A rabbit’s optimal air temperature is between 50ºF and 70ºF. Here are some different ways to help keep rabbits cool and somewhat comfortable. As the temperatures rise, so do a rabbit’s chances of getting heatstroke.
Rabbits with thick or long coats of hair, overweight, and young or old are at an even greater risk. Temperature, humidity and air ventilation are all factors that contribute to heatstroke in a rabbit. Rabbits are individuals and could respond to these conditions somewhat differently. It is important to check your rabbits consistently to insure they are comfortable and do not overheat. Early detection of heatstroke and proper corrective steps could mean the difference between life and death for your rabbits.
Before we venture into prevention and treatment, let us look into the signs and symptoms that will help you recognize that your rabbit has or is beginning to get heat stroke.
-The rabbit is fully stretched out. The feet are sprawled apart and the tail is limp.
-Wetness around the nose area
-Eyes are half closed. The rabbit has a sleepy or dazed appearance.
-The rabbit’s tongue is hanging out. His breathing is rapid and possibly labored.
-Fast, shallow breathing
-The rabbit is reluctant to move.
-The rabbit refuses to eat or drink.
The summer heat can cause your rabbits stress and health problems.
-Bucks can go sterile for several months if they are kept in a too hot of environment it takes up to 3 months for them to get back to normal fertility.
-Rabbits can lose condition and eat less food.
-Many times your bucks will go into molts and temporarily lose most of their hair.
-Lastly when a rabbit gets too overheated they can die from heat stroke.
Preventing heat stress is the key. Ways to help your rabbits survive the heat include.-Looking at the makeup of the common domestic rabbit, one sees that he is completely covered from head to toe in a thick fur coat. This leaves no way for the rabbit to perspire. There are virtually no means of which the rabbit can cool his body temperature other than their ears. The ears of a rabbit act as a temperature control mechanism, to warm themselves up or cool themselves down, they are able to do this because their ears are filled with blood vessels which run close to the surface of the ear. When the animal is too hot the blood vessels are able to cool the blood down from the cool air around the ear, the blood vessels are also able to warm the blood by the ears being in the sun, warming the ears and in turn the rabbit
Rabbits and heat are never a good combination, and heat stroke is one of the leading causes of death in rabbits. Fortunately it can easily be avoided, even if you do not have air conditioning.
Wild rabbits would spend the heat of the days in their burrows and go outside at night or early am when it is cooler. Here is a site That has housing ideas for hot areas – http://ressources.ciheam.org/om/pdf/c08/95605275.pdf
-Plenty of ventilation – Fans can be used but not best to have them blowing directly on rabbits. Place a cold, damp towel over a fan directed at your rabbit’s pen. As the water evaporates it will help keep your rabbit cool. Air flow is critical. Have a fan that is circulating the air. This not only makes the area cooler, but can help with the ammonia smell that can build up and increase in strength during hot days. And if possible, have the fan set up so that it is pulling the cool air in and not blowing against it.
-Plenty of shade- Keep them in the shade during the day. Ideally you would use trees to shade your rabbit building or hutches. I have grown sunflowers, pole beans on trellises to help shade my rabbits plus feed them! Natural shade is very helpful. If you have a shelter of some sort made of wood, which is then shaded by a tree, this is optimal. Being under a tree will make a big difference vs. being under a wood cover that is being hit directly by sunlight.
-Frozen ice cubes in a dish during hottest part of day
-Make sure there is enough space for them to stretch out to get cool.
-Ceramic tiles can be provided for them to lay on. If you place the tile in the refrigerator for an hour beforehand it will provide even greater relief
-Plenty of clean cool water. Cool water is important. Make sure they have cool water to drink to cool themselves down. If their water is hot, it not only causes them to drink less, but also keeps them from cooling down when needed. You may need to change their water 3 or 4 times a day during the hot months. And if you have an automatic watering system, make sure you have some way of flushing the system to get the hot water out of the lines and cool water in several times a day.
-Frozen liter bottles for them to lie against. Fill two to three one or two liter bottles about eighty percent full with water and freeze them. Take one out, wrap in paper towels or with a thin, clean rag that you won’t care to be chewed upon. Place this in your rabbit’s pen. This will last between four and eight hours before you will need to replace it with a new one. Place the thawed bottle back in the freezer so that you may use it again. Your rabbit will lay next to, or even on this bottle and get great relief from the heat.
-Evaporative systems like swamp coolers work in dryer climates. If barn is small enough to be closed an ac window unit can be used but again ventilation is stressed.
-Wet piece of carpet-Carpets cut into small pieces dunked in water will retain water throughout most of the day. You will have to watch for soiled pieces and change out for clean ones.
-Wet bricks – Soak them in a bucket of cold water. The bricks absorb the water and retain the coolness for hours.
-Feed in early morning or late in evening. Leave them alone during hottest part of day.
-I recommend spill proof crocks in the hottest part of summer over water bottles as the crockery holds the cool temperature of the water making it less likely that your rabbit will have to drink warm or even hot water
-Misters can be used also. If your aisles are 4’ to 5’ wide, place the mister down the middle. If you use “J” feeders, you may need to cover them to keep the feed dry. Do not let the water mist on the rabbits. Misters will lower the temperature 10-15 degrees in dryer climates.
-Outside hutches – Staple a burlap bag to the roof of the cage and have it drape over front of the cages. Place a soaker hose upside down close to the front of the roof edge. Set the hose on a timer or turn it on manually. The water will run over the burlap and act as a swamp cooler. The rabbits will lay closer to the fronts of their cages for the coolness.
-Avoid keeping multiple rabbits in the same cage. When you have multiple rabbits sharing a cage, their shared body heat contributes to a hotter living environment
When you are able to put most of these together; the cages being under a shelter which is under a tree, with cool water for them to drink, frozen 2 liter bottles in their cages, with air flow from a fan and a proper misting system, your rabbits can get through the scorching summer heat.
If you discover one of your rabbits are over heated there are a few things you can do to help, if caught in time
-Wet rabbit’s ears with a cool wet towel
-Place cold packs against the body moving around slowly but do not leave there.
-If they are alert water given orally is important
-As a last resort, dip your rabbit into cool water, taking care to keep her head and ears above the water. Most rabbits will not like this, and though it is effective, it will likely cause undue stress for your rabbit
If you breed during the summer months, you know how hard it is to keep those bucks from going sterile and keep those kits cool. Here are a few tips for those.
-Keep your bucks a close to the ground as possible. The cooler the better.
-Load the bucks up in carriers and bring them inside during the hottest part of the day.
– Bring the nest boxes inside to keep cool. Number or put the name of the doe on the boxes so you know where they go when returned. If the kits are likely to come out and explore while in the house, set them in your bathtub. If they are all the same color, you may want to number their ears so you know where they go later.
-If you need to breed your rabbits in the summer months I recommend that you use all wire nest boxes to help keep your newborn kits cool. Alternatively you can take your nest boxes indoors for the day and bring them back outside in the evening. If neither option works for you, simply be sure to keep your rabbits in a well shaded environment and maybe try running a sprinkler.
Remember- an ideal temperature for your rabbit is in the fifty to sixty degree Fahrenheit range. Any day above eighty degrees is a potential problem for your rabbit. With care and prevention your rabbits will enjoy many productive comfortable summers.
MAKING SOLAR FANS- I have had a lot of question on my solar fans i use in the rabbitry. I have made many different types some with batteries, and some that just work when the sun is shining. I Have 2 ventilation fans made from 2, 12 volt automotive fans one intake and one exhaust. These i have hooked up to a battery bank on a toggle switch. I am working on a timer to turn on for 15 minutes in 30 minute intervals this is a current project i am working on. I have a small wind powered charger i have made and solar trickle chargers to keep the battery bank charged. Also the lighting is 12 volt spotlights and i will be hooking up an inverter and even a 12volt car-radio and alarm (For rabbit thieves). For my outside hutches a have made smaller fans out of scrap items here is the information everyone has been waiting for!
Solar panels convert energy from the sun using wafer-based silicon to produce electricity. Making a solar fan is ideal for cooling rabbits. You can customize the system as your needs grow to add more panels and a bigger fan (I am constantly updating and changing these as i perfect the setup). All the fan parts can be bought from your local electronics store or found from old computers. When i was taking apart an old computer i discovered a lot of very cool parts that i could use to make stuff. One of the cooler ones was a 12V dc cooling fan. I also got the capacitor off a circuit board (just unsoldered it) I decided upon making a solar powered fan out of it. It’s really pretty basic.
– 6-watt, 12-volt solar panel (Instead of buying a solar panel i soldered solar panels from path lights together to get the voltage i needed)
– Circuit box or any enclosure
-12-volt, 0.25A computer fan
-Large 25-volt capacitor
1. Connect the red (positive) wire on the 12-volt fan to the positive side on the capacitor and to the red (positive) wire on the panel by soldering each connection point.
2 Connect the black (negative) wire on the 12-volt fan to the negative side on the capacitor and to the black (negative) wire on the panel by soldering each connection point. The solar panel will power the fan, and any extra power will be temporarily stored in the capacitor, like a small battery. When there is a shadow over the panel, the stored power in the capacitor keeps the fan going.
3 Cut a hole in the lid and base of the box with a hand or jig saw the size of the fan. Any enclosure can be used.
4 Align the fan in the opening, hot-glue it around all sides and then hot-glue the capacitor next to the fan.
You could also use batteries (AA batteries i got from the solar path lights) and use the solar power to charge the batteries and put the fan on a off/on switch. I took a battery holder (2 AA batteries) and wired it into a 1.5V to 12V step up circuit. Now that i had it outputting 12V i hooked it into the fan. Finally i hooked a PV cell into the circuit so that it would charge the batteries. This is a ongoing project i have been working on to perfect this setup
Questions i have been asked-
Is it mandatory to use capacitors in this project?
Yes it is absolutely mandatory to use a capacitor as the solar panel will power the fan, but if there is any extra power generated then it will be stored in the capacitor just like a small battery. In case there is a shadow over the solar panel then the stored power in a capacitor will keep the fan running.
How can the output of a solar fan be enhanced?
To improve the power of your solar fan, just double the output of the solar panels. You can do this by using more solar panels and by connecting them in series-parallel.
1. Before connecting the various parts, make some holes on the box and then connect the various parts in such a way that the fan and solar panel will stay outside the box and rest will be inside it. Pass the wires through the holes on the box first and then connect.
2. You can customize your fan as your needs grow by using more panels and a bigger fan.
3. Check the connections using a multi-meter.
I have also seen some solar fans on eBay i do not know how sturdy they are but they were very inexpensive and they also had larger more expensive ones .
