The newspaper opens diet secrets for nutrias.
Hay belongs to rough sterns, which skarmlivayut to nutrias mainly during the winter period at free, semi-free and cellular (or volyerny) the contents. It is considered the most kachestvenyony the hay of bean cultures containing a large amount of vitamin A. It feed generally to pregnant females and young growth. At a soyoderzhaniye of nutrias in bondage (cages, open-air cages) hay zakladyvayut in nested office. During the winter period, during hard frosts and bad weather, office zapolnyayut up to the top, and also put hay in fodder office of a cage.
Supervision showed that about a third of zeyoleny forages and hay (depending on them kachestva and a way of a skarmlivaniye) a nutria don’t eat – trample, scatter, bring in water or ispolzuyut as a laying in a nest.
Except hay, nutrias willingly eat a hay flour from leaves of a lucerne, a clover, esparceta. It feed in a combination with drobleny and zaparenny (or provayorenny) root crops, a silo or kontsentriroyovanny sterns. On nutritious properties the hay flour is close to the concentrated sterns therefore in a diet for nutrias it is possible to replace with it more than 20 % of concentrates. Experiences showed that the hay flour received from needles of a fir-tree and a pine has a great value. It feed to nutrias, adding on 5 – 6 g (on one adult small animal) to the humidified grain sterns or root crops. Hay and a hay flour store in a dry and pure room.
Vetochny forage – very important addition to racionu nutrias, especially at the maintenance of animals in nevole (cages, open-air cages). It is added to the basic kormu at any time by years. To nutrias feed branches of a willow, a rod, a maple, an oak, an ash-tree, a birch, and also plodoyovy trees. They willingly eat green leaves, koru, young escapes. The bark and wood contains many nutrients, mineral elements and vitamins. Therefore first of all the vetochny forage should be set to pregnant females and young growth. It is very important to observe thus norm of giving as the skarmlivaniye of a large number of a vetochny forage (especially oak escapes) can cause a zayopor in nutrias. In this case from a diet exclude for some time a vetochny forage, and to small animals give poslablyayuyoshchy forages – root crops (a dining room or fodder beet), a silo, etc. For the winter a vetochny forage zagotovlyayut in the form of brooms.
On all vital processes of a nutyoriya vitamins (first of all And, D, E, C) have a great influence. At the semi-manumission and the manumission cultivation systems when the poyodavlyayushchy quantity of animals lives all the year round in the reservoir which has grown with water and marsh and coastal vegetation, they have no avitaminosis. And here conditions of the cellular contents – lack of a svobodyony choice of nutritious veyoshchestvo necessary for an animal and the vitamins, the closed space of a cage, a lack of a sunlight, the air containing amyomiachny pairs, noise and other "delights" – can privesti to a disease of nutrias avitaminosis. To diagnose sick small animals it is quite difficult, as a depression, refusal of forages or its bad poyedayemost, the tousled wool and others simptomy are characteristic for very many diseases. However supervision over the nutrias, containing krugyoly year in bondage, helped to reveal a characteristic symptom of avitaminosis – it is change of coloring of cutters at animals. At healthy individuals cutters bright oranzhevogo colors, at patients – pale yellow, with dark, well appreciable spots. Zabolevyoshiye animals become languid. The shortcoming vitaminov is negatively reflected in their ability to reproduction: at females at an early stage of a bereyomennost the resorption (rassasyvaniye) of a fruit, on later – an abortion and the temporary infertility subsequent to it is possible. It is necessary to consider that the lack of vitamins is especially shown in the spring.
