We are what the animal DIDN’T eat. Maybe you have to read this sentence twice (at least I had), but it makes sense. We can supply animal diets with so much more functional ingredients, to become a healthier person in return.
Animal nutrition = Human health

The sentence that I start this week’s Editors View with was mentioned at the Alltech symposium, which I attended this week. The annual symposium, themed What If? aimed to highlight the opportunities in animal nutrition, crop science, human health and much more.

Use resources more efficiently
What if we can produce more meat with less water, what if we can supply all humans with enough DHA (omega-3) through enriched milks and eggs, what if Africa can actually be the next bread basket of the world. Interesting questions and the answers are not science fiction, the implementation of measures to make this happen is already happening today. The What ifs are essential as agriculture is facing many challenges today including: reducing or freezing the current agricultural carbon footprint, growing more on the current farms we have, use resources more efficiently, shifting the way we eat and reduction of waste in the food chain. Only then, we will be able to feed the growing world population, as mentioned by Karl Dawson from Alltech.

Big data, but how to implement them?
I agree that we have to change the way we are managing the farms and the way we look at food production and I think that technology is one of the major contributors to a more efficient and sustainable agriculture. Technology has already made such a big difference in crop science. Drones are used more often to generate data and inspect plans, a robot bee is under development to make pollination of crops possible in light of the decline of the honey bee population worldwide. With technology, I also mean interpretation of big data. How to make sense of all the data generated from the animal and human genome. How can we transfer this knowledge to make better animal and human diets? Also more data is generated from soils. We need predictive models to make sense of this tremendous amount of detailed information. David Hunt said during the Crop Science session: “Technology could greatly reduce the risk of experimentation in agriculture that prevents breakthroughs, since farmers cannot afford to gamble on a crop that may take nine months to come to fruition, Hunt said. But if the right data is collected through sensors, agricultural innovations could simply be tested virtually – using computer models, rather than actual crops.”

ADHD prevention with algae?
Another interesting topic mentioned was that people working in the animal feed industry should be more aware of the fact that animal nutrition is all about human health, as it is one business we are in: the food industry. Take the Omega 3 story for example. The good fatty acids (Omega 3) consist of DHA, ALA and EPA. ALA is coming from vegetable sources (e.g. flaxseed) and EPA and DHA from fish. DHA is the most healthy one, and the conversion of ALA and EPA into DHA is very limited. DHA is found in the fatty fish species as they have consumed algae in their natural diet. But more fish are farmed these days, and diets contain more alternative (vegetable) protein sources. Studies have shown that, between 2005 and 2008, trout fillets have decreased 9% in DHA and EPA levels and 8% in omega-3 levels.  Does this mean that human diets are getting deficient in DHA? At the symposium, it was mentioned that algae can be a great answer to many challenges we have today regarding raw material supply, human and animal health. DHA helps in preventing human diseases and may play a role in the prevention of ADHD in children. But also for animals, algae show promise. Studies have shown that algae in fish diets show good results and fish even don’t seem to mind inclusion rates up to 15%. In a recent trial with an algae product supplementation in dairy diets, researchers reported an increase of 1.9 kg per cow per day on average from day one to day 84. The milk also had an improved fatty-acid profile, increased levels of EPA and DHA and a reduced ratio of omega 6 to omega 3.

Role for animal nutritionists
Algae tablets for humans are already under development and there is an increased interest in adding algae in animal diets. Animal nutrition is not only about animal production and animal health, animal nutritionists also play a vital role in human health. We are what the animal DIDN’T eat. But what if we become what the animal DID eat (algae and other future functional ingredients?), we might become older, wiser and even have enough food to feed the next generations.

 

Raising Quails -Two Weeks to Five Weeks

2014-04-26 - No 18 - 5

 

It is of the utmost importance for any living organism to have a good start in life. Because of the many questions relating to Quail rearing and feeding, I have decided to post a series on the subject, mostly reflecting my own point of view and experience over a long period of time, backed by scientific facts.  The series will consist of  three chapters, i.e. 1 – Hatch to Two weeks ; 2 – Two weeks to Five weeks and 3 – Five weeks to Eight weeks.

2 – TWO WEEKS TO FIVE WEEKS

The birds, at two weeks of age, are old enough to have resolved all the genetic, hatching and birth defects and mortality should almost be zero from this point onward. Keep the brooder at 38 C and make sure the bedding is dry and clean. If there were to be any spillage of water or dirt, remove the soiled bedding and top up with clean dry bedding at all times.  Dont overcrowd them, keep them dry, warm,well fed and watered.

As they are growing at a phenomenal rate and are due to reach 90 – 95 % of their final body weight at five weeks of age, it is good to split the groups into two now. This will give every 10 birds about 0.25 meters square – enough to make them comfortable. Remember, we are trying to give our birds OPTIMUM conditions so as to allow them the opportunity to express their genetic ability to the maximum. Five week old birds are almost mature and it is a good time for selection on phenotype and measured production parameters to be able  to eliminate sub standard birds early.

Remove and dispose immediately of any animal that has any defect, being it a hereditary defect or otherwise, or is in the bottom 30 % of measured production parameters.

The mass of the birds are increasing rapidly during this stage so always ensure that the birds have enough space and that the feeders and drinkers are positioned in such a way as to allow free movement and not cause dead traffic spots inside the brooder.

The time has also arrived to teach the young birds not to enter the feeding and drinking areas, which is exactly the opposite to what has been thought up to now.  Any change in feeding and drinking routine should happen over a period of time. Leave the old feeders in place and introduce the new systems in parallel, then after two days, remove the old ones. This should minimise stress and assure continuous optimum performance.  Allow 30 mm slots, at an appropriate height, for the birds to poke their heads through to eat or drink – this will also be small enough to not allow them to enter the feeders.

Feed should be a well formulated 28 % protein Quail Starter diet containing the correct ratio of amino acids and other macro elements, supplemented with the correct trace minerals and vitamins. Mix one chicken or four quail eggs (without shell) per 2 Kg of feed for the age groups two weeks to five weeks. Raw egg is beneficial if correctly and well mixed, alternatively mix in boiled eggs. Feed consistency must be fine and uniform bite sizes, but not dusty.  If using a commercial diet, it is more often than not beneficial to supplement the diet with a trace mineral and vitamin pre-mix over and above what is supposedly already in the diet. It is virtually impossible to over dose with these nutrients, but deficiencies often occur effecting vitality, fecundity, mortality, disease resistance and production negatively.  Trace mineral and vitamin deficiencies are very difficult to detect or measure under normal conditions, unless their is a severe shortage, but will always effect the animal negatively.

Lighting intensity is still the same as for the juveniles and still at 24 hours per day. allowing them maximum time to feed

Should you adhere to these few simple guidelines, you will not only have happy Quails, but also raise Quails successfully that will perform to their ability when mature

Raising Quails – Hatch to Two Weeks

1 - 2014-01-30 - Coturnix Juvenile Group

It is of the utmost importance for any living organism to have a good start in life. Because of the many questions relating to Quail rearing and feeding, I have decided to post a series on the subject, mostly reflecting my own point of view and experience over a long period of time, backed by scientific facts.  The series will consist of  three chapters, i.e. 1 – Hatch to Two weeks ; 2 – Two weeks to Five weeks and 3 – Five weeks to Eight weeks.

1 – HATCH TO TWO WEEKS

Remove the incubated quails as soon as possible after hatching and transfer them to a pre-heated brooder at 38 C. This is to eliminate possible unfavorable conditions that may exist inside the incubator, such as high humidity, lack  of proper walking surfaces, competition with other hatchlings in and amongst other  hatching eggs, lack of  assistance and attention for needy individuals, etc.

The bad thing about this practice is that it may create unfavorable conditions for  the incubation of the rest of the eggs, as the incubator is being opened and closed often. This can be negated by doing it quickly and having the incubator in a favorable environment like a warm room.  Fast removal of  hatchlings  means that the incubator is not open long enough to change the egg temperature and moisture content significantly and does not have an effect on hatchability.  When hatching is at its peak, remove the chicks from the incubator about once every 60 minutes.

Remove and dispose immediately of any animal that has any defect, being it a hereditary defect or otherwise.

The brooder should be lined with a soft material like an old towel which will provide enough traction for the young birds to get onto their feet, without  slipping, sliding and stumbling. Make sure the surface is not slippery, or too rough as to entangle their small feet and toes. The weak hatchlings need to get onto their feet as soon as possible to exercise their muscles and respiratory system, without being exhausted.

 

2014-05-09 - Traction

The heat source must be of such an intensity that the chicks do not hover on the perimeter of the glow of the lamp, or form a nervous pile at the point of highest temperature right under the lamp. If the temperature is correct, the chicks will spread themselves out evenly under the heat and be calm, if this does not happen adjust the temperature until they are happy. This steady temperature must be retained 24 hours per day for at least the first five weeks. It is a good practice to have more than one heat source per brooder, should one fail, the temperature would not drop too low nor too fast to cause hypothermia and death. Young quails at this stage are very vulnerable and die very quickly should the temperature fluctuate too much. Adjust temperatures, by changing to different strengths of globes and changing the distance between the birds and the heat source. It can also be done by having one heat source supplying about 70% of the required heat and a second connected to a thermocouple set at 38C.

2014-03-22 - Day 1

Population density for the first two weeks should be about 80 – 100 birds per meter square. It is beneficial to have them in smaller groups of about 20 per 0.25 meters square,which enables easy access for the chicks to feed and water. during their learning period.  It also makes bird observation and management much easier.

Once the chicks are stable and dry, clean fresh food and water should be introduced and be available at all times. The food and water must both be easily accessible to the young chicks which will tend to congregate under the heat source. The food and water must be presented in such a way that the young birds can enter both the feed and water areas. Put the feed on the floor just outside the center of the heat source and the water a few inches away, but in the main traffic area of the quails. Make sure there are no blind corners where the youngsters can get stuck.

2014-05-09 - Day 1

 

 

After two days, exchange the cloth for wood shavings.  Keep the wood shavings until the quails are removed from the brooder at about seven weeks of age. Keep the brooder dry and fresh at all times by adding fresh shavings when needed.

2014-05-25 - Relaxing

 

Now also introduce feeders and larger water drinkers, as the chick should have learned to eat and drink by now, which still allow the chicks direct access to the feed and water
