Feed formulation- square method

THis is used by novice animal  nutritionist as a starting point in the study of feed formulation. You can compute the proper mix of ingredients to attain a certain amount of CP or crude protein.

example.
If you have corn and soya. (CP of certain ingredients sometimes varies depending on the book you have as a reference.)

Assuming Corn has 11% CP while soya 44% CP or crude protein. In a prestarter ration (swine) you need a 21% crude protein mix, so, how many  part of corn and soya should i mix to attain 21% crude protein.




the 23 parts  is attained by subtracting 21 CP with the CP of the soya which is 44.
the 10 parts is attained by subtracting the 21 CP  with the CP of corn which  is 11

33 is attained by adding the 23 parts to 10 parts.

following the formula  we attained 69.7% parts corn and  30.3% parts soya.

So if we want a 50 kg feed with 21% crude protein:
50 kg x 69.7 =3485/100= 34.85 kg corn
50 kg x 30.3%=1515/100=  15.15 kg rice bran
                              total 50 kg of feeds with 21% CP



NOTE: there should be no negative number in the formula. Example if you use soya with a 44 % CP. and your target is 21%CP , 21-44= -23. drop the negative sign. it should be 23 parts only.


***** I have edited the former data because there should be a value that is higher than the desired CP. On the previous example both source of CP are below the desired CP.... Sorry for mistake. I have overlooked the values.... THe principle is still the same as the previous post....

This a rough estimation:

Prestarter=20-22 CP
starter= 18-20 CP
Grower =16-18 Cp
Finisher= 14-16 CP

Sir, we have lots of ipil-ipil trees in our property and still multiplying. Is there other process to use this as feed for cows or goats not just cutting them and feed to animals right away.

Thank you in advance of your advise.

It's is usually feed sundried.

Also be reminded that you could only feed it in small amount to your animal because it have a toxic substance called mimosine.

Hello Doc,

Is it safe to say that combining 1 part rice bran and 1 part corn would result to an average of 21% to a maximum of 23.7% Crude Protein? How about the calcium content? What would be a good, safe & cheap source of calcium?

Hope anyone to reply as well.

Yup around that range siya.

Calcium source could be oyster shells etc

You’re right yuan.ai.centrum. I have to look for my files & correct it. Unfortunately, I was not able to follow-up on this formula because I was not so sure if I was going to compromise by experimenting this method. Another is that I have not received any scientific endorsement from anyone who would dare to try out this formula.
My apologies goes to those who asked me to respond to their emails regarding the feed formulation. I have not done so because I was & am still skeptic that this might not work out. I had problems with the way the pigs digested myh formula –for whatever possible reasons, I had to abandon this formula.
Instead, I ventured on experimenting on Doc Nemo’s Feed formulation- Square method. It would be interesting to note that this formula needs to be supplemented with very effective energy boosters & vitamins which are readily available from our veterinary shops. It might be worth to share my experience this summer regarding the 7 sows that I had been developing.
My first among 7 sows just went on heat. The square method that I chose to follow did not bring about the expected weight though, which should fall around 85 kg in 5 months from birth, in lieu of growth feeds readily available. Instead, my sows reached only an average of 76.3 kg in almost 8 months' period with the square method. I feel that this is not so bad because I have noticed that sows increase in weight tremendously after mating. Gestation does an incredible job to the pigs’ natural growth as though it recuperates for the loss it earlier lost, so long as adequate injectable energy boosters are provided.
It is not bad at all because I have consumed only 4 sacks of growth formula to augment the growth redundancy & about 20 sacks of rice bran & yellow corn (bt variety) for all 7 sows. I am happy to tell everyone that with prevailing prices based here on Iloilo I have only spent at more or less, P15, 800.00 in feeds for 7 sows to grow to full maturity which is only  P2,257.14 per sow. A pig averaging 75 kg thereabouts should gross at least P6,000 which, on my observation is not so bad because I only spent 37.6% cost of feeds.
I might experiment on the the feed formulation that I altered based on Doc Nemo’s formulation as soon as I could look for a good miller for my raw ingredients. My first experiment failed because I have noticed that these weren’t digested well based on the pigs’ droppings. But with Doc Nemo’s Nemo’s Feed formulation- Square method, I am now quite confident about the feasibleness of going into serious hog raising. If my gutt feel is right, there in money in hog raising.

Doc, if I can find an efficient miller to to grind my feed ingredients, what would be the ideal sizes so that the pig could be able to effectively & efficiently take advantage of the nutrients available in these? You see Doc, as posted, droppings of my pigs make me doubt that these have not been thoroughly digested & sayang naman kung hindi magagamit nga hayop ang mga available nutrients -di ba po Doc?

Anyway, I am about to consume all my feeds that I harvested for the summer. By mid august or early September, my corn would then be harvested. I am hoping for a good harvest BUT, I have a major problem that often occurs perennially. The wet season's continuous pouring unable us to dry our produce to the desired moisture level for long time storage. Besides, our corn crops become damp where molds & insects compromise the quality  because of the continual downpour.

In relation to this, may you advice, or anyone for this matter, how we can effectively, store our feeds in good condition until the next harvest?

Thank you for your valued suggestion

sa isa ko kasi nabasa ang hammer mill screen size is 4.7 mm so around ganun ang size nya dapat. Sad to say kasi i have an ebook about swine nutrition dati pero dahil nasira harddisk ko wala na me kopya nito.

Kung hindi siya matunaw then try po nila na icook ito to facilitate yun digestion ng animal.

Big problem nga po ang moisture... the only way to go around this is kung may indoor dryer sila or oven na pwdeng pag lagakan nito para matuyo. Try to ask your local DA kung meron ba silang post harvest facility na pwedeng mgamit para patuyuan ng kanilan harvest.

Sir,
There is something wrong sa formulation, calculation or assumptions.

It will be impossible to create 21% CP from a combination of ingredients having only 11% & 12%.

One of the ingredients should have a CP of more than 21%.

Thanks for the correction Dont. Hindi ko na rin napansin yung values.
One of the ingredients should be higher than the desired CP....
 

I would try to correct it later na lang..
