Feeding advice
solution egg food
Solution egg food is a supplement to the daily seed mixture for cage and aviary birds. By adding solution egg food, the birds get the right vitamins and minerals. Solution egg food is suitable for year-round feeding, but it is even more important during the breeding period. During this period more is explicitly demanded of the birds. Consider, for example, the making of eggs, feeding the young and of course the growing up of the young birds later.
Supplementing Garvo’s egg food completes the bird’s diet. When the birds get the right nutrients for a longer period of time, a natural resistance build-up is created. Thanks to this resistance, birds are less vulnerable and less sensitive to disease (pathogens). All in all, Garvo contributes to the good conditions of the birds.
solution universal food
Solution universal food is a supplement to the daily seed mixture of European culture birds, among others. For some birds 3866 solution universal food is even the basis of a balanced diet. By adding solution universal food, the birds get the right vitamins and minerals. Solution universal food is suitable for year-round feeding, but it is even more important during the breeding period. During this period more is explicitly demanded of the birds. Consider, for example, the making of eggs, feeding the young and of course the growing up of the young birds later.

egg food
Seed mixtures alone do not contain enough vitamins, minerals, amino acids and trace elements. Therefore, give all seed-eating birds regularly egg food so that their condition, moulting and breeding results remain good. Garvo egg food is suitable for almost all birds, such as canaries, parakeets, parrots and tropical birds. Parent birds feed it to their young, and moulting birds can also use the extra nutrients.
- during the breeding season mix about 30% egg food in with the seed mixture
- if there are many young, increase the amount up to 50%
- for the separated young until after they moulted, mix in 30% egg food for example, with the seeds
- during the moulting season mix in every other day 25% egg food with the seed mixture
- during the resting period and before shows, mix in every other day 10-15% egg food with the seed mixture
- the above feeding advice applies to 5300 egg food, 5306 top egg food gropar, and 5308 RUL egg food
universal feed
Insect-eaters, such as red-billed leiothhrixes, superb starlings and bulbuls, need feed containing insects. For some birds, this is even the basic feed. Garvo’s 5305 universal paté (insectivore) contains, aside from insects, other proteins and fats of plant and animal origins, minerals and vitamins. This universal paté promotes healthy breeding, effortless moulting and an all-round good condition of the birds.
garvocyme
9508 garvocyme has proven itself as a valuable supplement with a positive effect on the health of the birds. It is based on baker’s yeast and contains the necessary proteins and vitamins. Hereby it also serves as supplementary feed.
grit and stomach gravel
Thanks to 4211 stomach gravel birds can more easily digest the nutrients from the seeds. Sharp stomach gravel serves as ‘molars’; it crushes the seeds in the gizzard, helping the digestive juices to work better. Grit is especially important if the birds are being bred. Special types of grit, such as 3347 oyster shell (1mm), 3340 oyster shell (3mm) and 4216 bird grit mixture have the right structure and provide the necessary calcium for building and maintaining bones. To make the care complete, give unlimited amounts of sharp stomach gravel and grit. Birds will consume a limited amount, but only what they need.
bird and shell sand
The floors of birdcages and aviaries, especially in the night roosts, should be dry and easy to clean. This is important in order for the birds to stay healthy. You can use, for example, 9620 birdsand special, or 9624 birdsand special with anis, which contains, among other things, oyster and seashells and a pleasant anis odor. Both sorts ensure that the bird dwelling stays hygienic.
