I would suspect that the reason for this may be the developing atherosclerosis in the rats fed ad libitum and its delayed development in rats on a restricted diet. . "Feeding Secrets" are told by a veterinary clinic and are illustrated by a 14 year study on Labradors.

A very detailed study ¹ shows that intestinal nutrient transport is greatly increased in animals on caloric restriction and suggests that their intestine has the potential to absorb nutrients at almost two-fold the rate than mice fed ad libitum.

Dr. George Roth of the the US National Institute on Aging points out that mice and rats live longer and healthier lives on a restricted diet as compared to those living on a diet ad libitum.

Many studies involving feed restriction have thus been done in mice or rats and almost all of them conclude that feed restriction has many positive effects. In one of these studies, cardiac, renal, and central nervous system pathologies were significantly inhibited by dietary restriction (DR), as were bone degeneration, inflammation, hyperplasia, amyloid induction, and atrophy of secretory organs. ²

A study on fruit flies concluded that feed restriction in these insects has only negative effects and it must therefore be asked how relevant the studies on feed restriction involving mice are to birds.
Broilers in one study were able to recover from mild feed restriction, and there was always an associated reduction in mortality.³

Another study with broilers showed mortality in the restricted-feed flocks was significantly lower than in the fully fed flocks aged from 3 to 7 wk. The economic performance with restriction feeding was better than that with full feeding as a result of improvements in viability and feed conversion rates. ⁴

It's understandable, therefore, that some fanciers would want to write "poison" on the feed tin because ad libitum and excess feed appears to cause various diseases and shorten the life span of mice, rats, dogs, monkeys, chickens and very likely pigeons too. Let us remember in this context that performance pigeons, be they the flying tipplers or our racing pigeons, will feel no desire to exercise if fed ad libitum. They obviously do not feel as well on excess feed as they could on a restricted diet.

Still, good pigeon fanciers often worry about their birds not getting enough feed and this can easily be checked by giving the birds a bath: do they all jump eagerly into the bathtub? If so, rest assured that they are getting enough. A bird who does not feel well will not take a bath. Another way of checking it is to pick up some birds from the floor at feeding time and feel their weight. If one can't pick up any of them, they are probably getting fed too much. If they are too light or are too much into eating droppings, they are not getting enough. Increase their ration or check to make sure that their ration is not deficient in some required nutrient, deficiency of vitamin B₁₂ coming to mind. Constant attention is required in order to make certain that they do are neither over- nor under-fed.

Many fanciers feed performance birds such as racing pigeons on a limited to full cycle. The birds are fed sparingly in the beginning of the week and the amount of feed is gradually increased toward the end of the week culminating on shipping day when they get a full trough. The observant fancier will notice how more readily his birds take to their exercise flights as the week progresses and the feed increases. This effect would be much more difficult to attain with feed in front of them all of the time or by giving them an insufficient amount.

The following is a conversation picked up at the Alberta Classic Discussions:

• "Because we feed well as much as the birds need when moulting, they tend to put on a bit of weight. To bring them into breeding condition we lighten the feed, and give a little less for a week then we do not feed them at all for 5 days, in fact we do not go to the lofts. This happens the same with the widowhood cocks. Two reason one is they take no hurt because they live off their body fat, and the second is they have a good fall of down and once it starts it continues. We have done this for 25 years with no bad effects on the pigeons."
• "For pigeons to hit form they need to throw out down feathers. This will continue right through the season throwing out the down feathers especially when a bird is in form. If you notice the day after a race, I do not mean a short race, there will be an abundance of down feathers where the bird is perched. This is partly due to the effort the pigeon has put in the race a certain amount of stress, home it comes is fed and recovers then it starts to throw out some down feathers. I would be a bit concerned if I did not see them. Also an unfit, over fed pigeon will not cast down feathers. Hence when the pigeons were deprived of their normal feed it caused a little stress and did the job required, i.e loss of weight and started the fall of the down, with no ill affects on the birds."
• "Yes sometimes when a pigeon homes several days late from a race, it can hit form and the next morning after homing you will see a fall of down feathers. One thing this proves in many cases that the pigeon was not sent right the time when it failed but the race brought it on and did the pigeon a lot of good, hence, bringing it into the condition needed to win."

"Soup": 1 head of garlic + 1 onion + ½cup apple cider vinegar + 4 tbsp honey blender for 10 minutes.
Each bird gets always 30 gm feed per day. The fat mix consists of 66% peanuts and 34% hemp seed. (43% fat) The amount of fat mix offered depends on the expected distance of the race. Suppose that the next race will be from 520 km which can be flown in 520 minutes on a fast day. A bird requires 1 gm fat mix for every 10 minutes flying time which would be 52 gm. Subtract 12 gram for the fat in the regular mix which leaves 40 gm to be divided equally between Monday, Tuesday, Wednesday, and Thursday. On Friday the birds will get approximately 13 gm fat mix, the exact quantity depending on the the expected severity of the race.

Let's summarize:
• Saturday: The birds return from the race.
  • AM: 10 gr pellets ( birds need energy fast ); Per 500 ml water: 3 tbsp dextrose + 1 tsp vinegar + 1 tsp honey; fresh grit and picksteen
  • PM: 10 gm depurative mix + 10 gm pellets; Per 500 ml water: 3 tbsp dextrose + 1 tsp vinegar + 1 tsp honey; fresh grit and picksteen
• Sunday:
  • AM: 10 gm 50% pellets, 50% depurative mix
  • PM: 20 gm 50% pellets, 50% depurative mix
• Monday:
  • AM: 10 gm mix; 2 tbsp "Soup" per l water;
  • PM: 10 gm mix + 10 gm fat mix; 2 tbsp "Soup" per l water;
• Tuesday:
  • AM: 10 gm mix
  • PM: 10 gm mix (coated with wheat germ oil for longer races) + 10 gm fat mix
• Wednesday:
  • AM: 10 gm mix + vitamins
  • PM: 10 gm mix (coated with wheat germ oil for longer races) + 10 gm fat mix + vitamins
• Thursday:
  • AM: 10 gm (mix + 30 to 60% corn)(coated with oil) + vitamins
  • PM: 10 gm (mix + 50% corn)(coated with oil) + 10 gm fat mix; after this as much corn as they like. + vitamins
• Friday:
  • 4 hrs before basketing: approximately 13 gm fat mix, the exact quantity depending on the expected length of the race.

Sunday January 4, 2004 JACK BYERS EYESIGN GUY MAGALI CA 95954, CA. 198.81.26.10	YOU SURE HAVE A GOOD SITE
Sunday January 4, 2004 Robert Lynch Tifton, GA, USA 207.69.75.252	Interesting reading. Could overfeeding be associated with increased losses in youngbirds as several of the reported studies indicated that animals on a restricted diet learned quicker than those on a non-restricted diet. Something to think about!
Monday January 31, 2005 Gary Johnson Menomonie, Wisconsin 68.21.128.55	Very difficult to strike the balance, underfeed them and they will go looking for food else where, fielding we used to call it in England. If they go looking for food they will be out of the loft longer and increase the chance of being food themselves (hawks), also if they go fielding they are not getting the exercise that you want them to get.

Monday September 11, 2006 gez kirwan Birmingham UK, ENGLAND 82.36.147.202	great site learned a lot about racing pigeons http://www.freewebs.com/racingpigeonsbirmingham kirwan and son lofts
Wednesday July 23, 2008 alexander smithy tagaytay, philippines 58.69.14.17	your study are very complicated! idont leared much! what i know and it is base on my expirience, racing pigeon will eat what only they needed to have complite Vit. and minerals to thier body, and you must provide it for them.
Thursday January 29, 2009 Percival Lorbes Makati City, Philippines 61.14.197.226	Your site is great. Discussion on your sites were also great I learned a lot. Thanks and kip it up.
