Anatomy - Wikipedia
Anatomy (Greek anatomē, “dissection”) is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science which deals with the structural organization of living things.

Other italian trials on produced similar conclusions in a trial where this sun-dried fern fully replaced soy cake in the ration at 23 percent. There is another use for guinea grass dried, the plant is sometimes used as straw litter for the nest box when breeding does are raised on a mesh floor. The optimum dose of crude protein for the breeding doe seems to be roughly 17 to 18 percent.

Its high (25 percent) protein content makes it a valuable source of nitrogen for rabbits in mozambique, especially during the dry season. Bile from the liver contains bile salts and many organic substances which aid digestion, but has no enzymes. Amino acid balance can easily be achieved with plant protein alone as in almost all balanced european feeds.

From then on the soft pellets follow the same digestive process as normal feed. Sowing and tillage are no problem in soils where grows naturally (e. Growing naturally in the semi-desert area of northern mexico, this member of the gourd family has an enormous root that is 65 percent starch.

Feeding trials in egypt using the clover alone produced live weights of 1. Much of the food value is lost when the product is stored, however, and rabbits tend not to like it. So it is hard to set a strict energy requirement, but it has been shown that intake is only correctly regulated between 2 200 and 3 200 kcal dekg of feed.

As with pigs, this must be an effect of the growth-factor type. The best feeds are thus established and the best mixes selected, allowing nutrition experts to draw up recommendations for several categories. Their feed can be slightly less rich than that of young growing rabbits.

Potato peelings are part of the kitchen waste in many countries and can be used in feed. In dry areas they virtually stop growing during the dry season, but remain green. But growth trials on the island of mauritius show that can replace 40 and even 60 percent of balanced feeds without adversely affecting animal growth or health (figure 6). Unless otherwise indicated, nutrient content, where shown, is expressed as a percentage of dry matter. Each feeding place along the rack should be 7 to 8 cm long.

Anatomy and Physiology The Chemical Basis of Life This forage grows without irrigation in the dry season in mozambique and has a high (20 to 21 percent) protein content, making it an attractive forage feed for rabbits. It contains 100 to 120 g of a uniform pasty mix with a dry matter content of about 22 percent. However, between weaning at five weeks and the close of the 12-week trial, Sugar cane can be grown in countries with wet tropical climates and is a good rabbit feed, despite its low protein content (1 or 2 percent). In a few days the intake of solid feed and water will exceed the milk intake. In a complementary trial, the same authors found that, fed ad lib, rabbits chose to replace up to 40 percent of their balanced concentrate feed with chopped sugar cane.

    This tropical legume is commonly used to feed creole rabbits in guadeloupe and martinique. In units with more than 300 does it is preferable to use two or three types of feed one suitable for lactating and breeding does, one for the weaning period and the last for growing rabbits in all other categories (e. They produce a milk three times richer than cows milk, at the rate of 100 to 300 g per day, and have few reserves in relation to the demand made on them. The proteins in both the tops and the groundnut cake lack the essential sulphur amino acids. The rabbits response to the quality of the proteins in its diet, long a controversial issue, has now been established beyond doubt.

    It remains in the stomach for a few hours (three to six), undergoing little chemical change. This problem is solved by compacting the mixture in a pelleting machine. Legumes of this genus can be grown in all wet and dry tropical climates. In a few days the intake of solid feed and water will exceed the milk intake. Wild vetches, grown alone or interplanted with grasses, can supply a protein-rich forage attractive to rabbits.

    Bile from the liver contains bile salts and many organic substances which aid digestion, but has no enzymes. It does not grow in hot tropical areas such as the caribbean. Also tested in malawi as a maize bran supplement, used as a supplement to a broiler chicken feed, growth rates of 100 to 110 g a week were recorded. This protein-rich (24 percent) forage, used in mozambique to feed rabbits, grows during the dry season. Alfalfa is unquestionably the standard rabbit forage, wherever it can be grown. The total feeding time in a 24-hour period exceeds three hours at age six weeks. Table 17 changing feed habits of nine new zealand white male rabbits aged from 6 to 18 weeks, given water and balanced feed ad lib in a room kept at 201c figure 3 hourly distribution of daily intake of water and balanced pelleted feed of a 12-week-old rabbit aver a period of 24 hours the rabbits energy expenditure depends on ambient temperature. Growth performance trials with this egyptian clover (berseem), typical of the mediterranean climate, is virtually the only rabbit feed used in the sudan. Data are available on the leaves as rabbit feed, but not on the stems. Recommendations now made on quantities of indigestible crude fibre to be fed are therefore given below.

    The human body is composed of elements including hydrogen, oxygen, carbon, calcium and phosphorus. These elements reside in trillions of cells and non-cellular components of the body.

    Table 22 recommended chemical composition of feeds for intensively reared rabbits of different categories the recommended amounts of other essential amino acids have been estimated simply on the basis of regular satisfactory diets. The most common feed categories in intensive european rabbitries are for breeding females (lactating does, pregnant or not), young rabbits of weaning age (post-weaning or peri-weaning feeds, the latter also consumed by the mother) and rabbits for fattening. Amaranthus is routinely fed to rabbits at the bunda agricultural college in lilongwe, malawi. During this period the changes in feeding behaviour are remarkable the young rabbit goes from a single milk feed a day to a large number of alternating solid and liquid feeds distributed irregularly throughout the day 25 to 30 solid or liquid meals every 24 hours Anatomy and Physiology The Chemical Basis of Life cкачать бесплатно

    In the latter case, the intake rate and hence the function of caecotrophy are governed by the light regime to which the animals are subjected. The next category is growing rabbits (far more research work has been done on this than any other category). In these trials, even where this acacia was used alone, the authors noted no incidence of diarrhoea or symptoms attributable to mimosine. Laboratory animals stopped growing when they were given 20 g of green potato peelings a day in addition to their normal feed ration. Local rabbits grew faster with this feed (104 g a week with land race) than with an imported balanced feed (83 g).

    Incorporating 25 percent water hyacinth meal in a balanced feed gives good results. On the same line, two values having the same index letter do not differ from one another at the threshold p 0. Its function is mainly to provide crude fibre and a small amount of energy. This legume can be an attractive source of protein and fibre for rabbits. Considering the fact that some parts of the intake may be recycled once, twice and even three or four times, and depending on the type of feed, the rabbits digestive process lasts from 18 to 30 hours in all, averaging 20 hours.

    The aerial part of prickly pear cactus can be fed to rabbits. However, cottonseed cakes containing up to 700 ppm of free gossypol have been fed to growing rabbits with no problems Anatomy and Physiology The Chemical Basis of Life cкачать бесплатно без регистрации и смс

    As an indication, the minimum and maximum thresholds are given in table 24 for various minerals, some vitamins and essential amino acids. Modern hybrid varieties conventionally grown for human food can also be used for feeding rabbits. Content is generally evaluated on the basis of crude fibre, although this analytical technique is far from perfect. Brewers draff and citrus pulp are possible feed sources where the processing plants are not too far from the rabbitry. Digestibility of the nutrients has not usually been determined for the rabbit specifically.

    The consumption of solid and liquid intake fluctuates over a 24-hour period, as shown in figure 3. Where too much is supplied performance may drop, to the breeders surprise, and the risk is particularly high if he or she uses supplements that are added to the feed or drinking-water скачать Anatomy and Physiology The Chemical Basis of Life txt

    The energy needed for organic synthesizing is usually supplied by carbohydrates and to a lesser extent by fats. The feeding habits of wild rabbits are even more nocturnal than those of domesticated rabbits. Table 19 impact of ambient temperature on intake and excretion ratios in adult rabbits feeding rabbits forage plus supplementary concentrate feed raises problems when the forage is not very palatable. In new caledonia, a local hyacinth called water lily is also a traditional feed. The hard pellets are expelled, but the soft pellets are recovered by the rabbit directly upon being expelled from the anus.

    Banana peels can also be used to replace up to 35 percent of the concentrate for growing rabbits Anatomy and Physiology The Chemical Basis of Life бесплатно в epub

    If this is accompanied by a higher digestible proteindigestible energy ratio, rabbits will suffer energy deficit and protein surplus at the same time, favouring the excessive production of proteolytic digestive flora which produces ammonia and leads to increased digestive problems (figure 5, curve a). By the end of the morning there are large numbers of these pellets inside the stomach, where they may comprise three quarters of the total contents. Amaranthus is routinely fed to rabbits at the bunda agricultural college in lilongwe, malawi. Trials in the united states used up to 40 percent poplar leaves in the diet. The dried stems of comprising 30 percent of the diet of growing rabbits, sun-dried water-lettuce meal was used in nigeria to produce growth rates equal to those of the control Anatomy and Physiology The Chemical Basis of Life без СМС в формате pdf

    Taking as a reference animal an adult fed ad lib (140 to 150 g of dry matter per day, for example, for a 4 kg new zealand white) at four weeks a young rabbit eats a quarter of the amount an adult eats but its live weight is only 14 percent of the adults. However, fast-growing animals respond favourably to the addition of 1 to 2 ppm of vitamins b , and 30 to 60 ppm of nicotinic acid (vitamin pp) in the diet. In an early trial in mauritius, coarsely chopped sugar cane was successfully used to re place one half the balanced concentrate feed ration with no consequent drop in performance. As the contents enter the small intestine they are diluted by the flow of bile, the first intestinal secretions and finally the pancreatic juice скачать Anatomy and Physiology The Chemical Basis of Life в формате fb2 без регистрации

    However, even at sodium contents exceeding 2 to 4 g (6 g of rashid salt), no mortality was reported from this eight-week trial, and the rabbits still grew at a rate of 23 gday77 percent compared with the control. One feeding rack is enough for six to ten rabbits, but at least two are needed as a safety measure in case the pellet flow should get blocked. Cortisone injections of animals without adrenals causes the resumption of normal behaviour. The plant grows so quickly, however, that the tendency is to use it as hay, unless planting can be staggered for a continuing crop. Its attraction is its high protein content (28 percent) and the fact that it can be grown during the dry season.

    Some research indicates that rabbits need a certain minimum of fibre for regular digestion 9 to 10 percent of indigestible crude fibre
