In view of the enquiries in this forum, it may be useful if I share my experience of using the P28 brand of dry food for insectivores and also set out my criteria for choosing a dry food for my shamas.
Need to feed dry foodI have found that feeding purely live food to my shamas does not give the best results. The reason, I think, is that the limited variety of live food available in the form of crickets, mealworms, pineapple beetles, fish and froglets do not satisfy the complete nutritional needs of the shama.I therefore decided that a good dry food would need to be the shama's staple food and the live food would only be fed as a supplement. This requires that the dry food be as complete a food as possible if it is to serve the intended purpose.
Having tried many commercially available dry foods and finding none of them completely to my liking I ended by making my own dry food for my shamas. They were doing very well on this food but I have many shamas and the need to make dry food at periodic intervals proved to be a nuisance. I therefore looked around for a suitable readily available dry food.
I began to hear good reports from users of P28 and I finally decided to give it a try.
Over a period of several weeks, I gradually converted my birds to P28. I use it as the basic food and I add whatever I think might be useful.
My birds seem to do much better on P28 than other dry foods I had tried and I can assure you that I have tried many over more than 40 years. I now feed all my shamas except the breeders with a staple diet of P28 and some live food in the evenings. The breeders get only live food from the time they are paired.
I have 4 main criteria for choosing one brand of dry food over another and I consider them below.
The dry food should be scientifically formulatedIt is desirable that the dry food be scientifically formulated by nutritionists who know the requirements of insectivorous birds such as shamas. This will ensure as far as possible, that the food has the proper balance of protein, fats, carbohydrates, vitamin and mineral levels etc that the birds need.
My research showed that there are several brands of imported food available in Singapore for insectivorous and softbill birds. Amongst them is P28. This is a scientifically well formulated pellet food for insectivores.
I should mention that there is an insect based food that was in the market long before P28 and which is still available. I had tried it many years ago when it was first introduced into Singapore. I had rejected it as it did not satisfy my criteria for a suitable food. In any event, even the local distributor has admitted in this forum that he does not use his insect based food as the main food for his shamas but makes his own concoction and uses the insect food only as one of many ingredients. It seems to me that if the importer himself has no faith in his food, it cannot be much good.
I do feed dried insects to my birds so why did I find the commercially available insect based food to be unsuitable? I cannot be sure but my guess is that to reduce costs, the manufacturers of such food tend to purchase the lowest quality dried insects that is available.
Make a Google search and you will find that bulk sellers of dried insects offer them in several grades, say, A, B and C with C being the cheapest and lowest grade. Grade C will comprise of insects that are of very poor quality because of incorrect processing methods or overlong storage. If this grade of insects forms a major part of the composition of a food, the bird is not likely to find the insects palatable or nourishing.
Long usageEven though a food may not have been scientifically formulated, long availability in the marketplace and usage may establish its suitability. This is in fact the position with the local brands known as Synlin and Three Coins. My shamas seemed to do much better on these 2 brands than other commercially available dry food. Unlike the imported insect based food, my shamas found these 2 brands palatable. If a food such as P28 is not available and I do not wish to make my own food, I would probably use 1 of these 2 brands.
ExcretaYou can easily tell from the excreta of a bird whether it is insectivorous, or a fruit or seed eater.
The excreta of an insectivorous bird that eats live food will take the form of a patch of white with a bit of darker matter in the centre. The white matter is uric acid which is the result of a high protein diet while the darker matter is the actual excreta. A suitable dry food should result in the excreta being as close as possible to the excreta of a bird eating live food. P28 and the 2 local brands of dry food satisfy this requirement.
MoltThe best test of the suitability of a food is how well the birds do after eating the food over the course of the molt. If the food is correct, the birds should be singing even during the molt and by the time they complete the molt, their feathers should be in perfect condition and they should be singing well and in good form. One of my shamas has completed his full molt on P28 and I am happy with his condition and form. Three of my other shamas are molting on P28 and I am also happy with their progress.ConclusionI am no expert and there are many things that I still have to learn about the care of shamas. I nevertheless feel that it might be useful for others to share my experiences and whatever knowledge I have managed to acquire about shamas. Almost invariably when I do so, I set out the basis of my advice and/or the source of my information so that the reader can assess for himself if the advice is sound. I have unfortunately found that this is not always the case with advice that is often so freely given in the forum.
