This article rodolzhaet a subject of feeding of nutrias, opening secrets of their diet.
(Continuation. The beginning in No. 15).
At storage of forages in them there are decomposition of vitamins, proteins, oxidation of fats and other processes which negatively influence their quality. The quantity of useful substances in sterns sharply decreases and at the wrong thermal processing.
The concentrated forages are necessary for entering into a diet of nutyoriya at the semi-free and cellular contents as an additive to juicy vegetative sterns. In grain sterns more vsego contains protein, starch and fats. Nutrias willingly eat corn, barley, oats, wheat, and also millet, to Vick, a socheviyets, a sweet lupine. It is best of all to them to set grain mixes, zamoyochenny some hours prior to giving in saltish water. Peas, viku, to a sochevitsa, a lupine to a skarmlivaniye also previously zamachivayut to warn possible swelling of a stomach, other concentrated forages feed in the natural form. For newborn and young small animals grain razvarivayut. Kukuyoruza is more convenient for feeding in ears. In a diet it is possible to replace grain forages (0,5 norms) with others concentrated kormami, for example, a waste of flour-grinding production – vysevkami, corn shroty, dertyu, makukhy. Vysevki set densely mixed, and also in a combination to boiled thoroughly potatoes (as well as others grain] or with sterns of an animal origin and mineral substances. During hard frosts norm of grain forages increase, and root crops – reduce. Adult nutrias can feed acorns, replacing 0,5 normy the grain. However it is necessary to remember that they contain znachiyotelny amount of tannins, so, to set them it is necessary in a combination to juicy sterns. Acorns feed zhiyovotny and at disorder of digestion.
It is necessary to know that at a plentiful food by kontsentriyorovanny sterns and root crops at nutrias nablyudaetsya obesity which can lead to decrease in fertility.
Skarmlivaniye to breeding nutrias of baked bread from the nizkoyosortny flour half mixed with bran, small dertyu, with addition of a ground doll of a silkworm, chalk and salt much more povyshaet efficiency of small animals, and also improves quality of fur. Instead of a half of norm grain nutrias can set bread (on 70 – 100 g on one adult animal). To small animals who are subject to a face on a skin, for 1,0 – 1,5 months to a face in a diet are desirable for adding on 20-30 g a day linen or podsolnichnikovy makuxi which consumption favorably influences quality of fur.
In the winter and in the early spring when animals are deprived of green forages, it is desirable for them to feed about 20 – 25 % of norm grain (barley, oats, wheat) in the let germinate look. As the vitaminized forage it is very useful to beyoremenny females and the young growth left on a tribe.
Root crops replace juicy green plants which nuyotriya ate during the warm period of year. The first place in a diet (Nutyoriya fodder beet borrows, they well eat and sugar, but it causes thirst therefore to set it it is necessary together with a kormoyovy beet. A table beet enter into a diet gradually and vmeste with other sterns as it can cause disorder of intestines. Before a skarmlivaniye root crops carefully wash, clear of decay and set pieces (mass of 100 – 150 g), rasklayodyvy them in different feeding troughs. The nutria willingly eats carrots. Blagodarya to the big content of carotene, it is a valuable diyoetichesky product, and also a prophylactic protiv helminthic diseases. In the autumn animals can feed root crops or their tops of vegetable, leaves and the heads of cabbage containing many mineral substances. Nutrias eat them willingly. It is impossible zadavat for animals root crops frozen. Potatoes nutriyam set in the boiled thoroughly look. At the sprouted tubers surely delete sprouts as they, and also the tops of vegetable and green fruits kartofelya contain poison gas – solanin.
Fodder water-melon of a nutria eat willingly and in a big koyolichestvo, a pumpkin – less willingly, however it surely jam an animal as any its kind, in particular kavbuz (the water-melon hybrid with a pumpkin), contains a large amount of nutrients, and seeds besides possess glistogonny action.
Practice showed that nutrias during the winter period willingly eat a silosovanny forage unusual to them. Even in the presence of other forages they prefer a qualitative silo. The best silo for nutrias – from stalks and corn ears (in its dairy and wax ripeness) – 600 – 800 g of such silo can replace about 50 % of day norm of root crops and 25 % of day norm of the grain. At a skarmlivaniye to nutrias of a silo nuzhyono twice to increase norm of mineral top dressing (chalk) for a neyyotralizatsiya of the acids containing in it is mute that promotes luchshemu to forage digestion.
Forages of an animal origin (myasokostny and fish meal, dolls of a silkworm, mollusks, milk, serum) make an integral part of a diet of a nutria – it generally proteins, and also fats and mineral substances. First of all them zadayut to small animals who contain in bondage. Usually them zagotovlyayut for the winter also enter into a diet on neskolku gram on the head. Moloyoko set integral in a mix with porridges or bread, the main thing obrayozy to podsosny young growth and pregnant females, to them first of all set (3 – 4 g on the head per day) and cod-liver oil. At an okisyoleniya (rancidity) of the fats occurring under vozdeystyoviy of direct sunshine and at an open entry of air, flying aldehydes and ketones, and also nonvolatile substances of oxidizing character which very harmfully influence an organism of an animal, including on assimilation by an organism of vitamins are formed. And infection of fats sporami plesnevy mushrooms much more strengthens their toxicity. Therefore the forages of a nutria containing fats and proteins, neobxodimo to store in the refrigerator in densely corked container or in a dark cold room, for example in a cellar.
