The pig or boar-pig descends Eurasia. The adult male is the ‘boar’, the female ‘slut’ and the young are called piglets. The pig is fed all types of organic substance and food waste man Or delicatessen, when it is factory farming.
It is believed that the pig is one of the first animals used by humans for consumption. Domestication dates back years BC. The pigs were divided into three groups: Their Derivatives vitatus, these races are native to China and Indonesia.
Sus scrofa ferus derivatives, breeds originating in central and northern Europe. Their Derivatives mediterraneus, these races are from the Mediterranean. Is a pig from the United States of America. Its coat is usually red in all its shades. It is an animal that is well adapted to existing conditions.
Dasometria e Inventario Forestal
Good development of hams. The female weighs kg and males kg. The number of piglets per litter is 10 on average.
Pork is a native of Denmark. This breed is very prolific and excellent milk production, so offspring are usually very vigorozas. They are very docile animals which makes working with them. Excellent feed conversion, daily gain good. Sows can weigh up to kg and males about kg. The litters varying between 9 and 11 piglets on average. Belgium is a native pig. It’s a bit prolific race. Produce very tasty lean meat.
Good development loin and hams. The number of piglets per litter on average is 9.

Pork is a native of Yorkshire in England. For different ways to participate in food: Bananas and plantains are the number one fruit crop in the world, both in terms of production, about 98 million tons, and trade, valued at over U.
It is considered that the banana is known internationally as the fruit of the Banana, was one of the first fruits cultivated by man, the oldest references concerning Bananas are in the Ramayana, an epic poem written in Sanskrit centuries.
The victorious armies of Alexander the Great described cultivation in the lower valley of the Hindus in India, in BC, where there were already references written between Southern China is another area where the cultivation of Banana and Plantain goes back to ancient times, the writings of the reigning period of the Han Dynastymentioned that the cultivation of Banana and Plantain practiced for over years.
Since ancient times, its long history of domestication in India and China, and the wide range of dessert and cooking cultivars that are in those countries, some writers believed that bananas and plantains were there originally. The higher incidence of disease and further damage to the general Musa are black Sigatoka, Sigatoka disease, elephantiasis, viruses and Moko.
We must understand easometria difference between pests and disease as the plague usually represents an attack of insects and other “bugs” and disease, refers to fungi and bacteria. Black Sigatoka, treat it in a separate chapter and Yellow Sigatoka Micosphaerella mussicolla is a slightly less aggressive fungus, but dorestal attacks the plant leaf, influencing the production and bunch weight.
There are some varieties of Musa yellow sigatoka resistant as most bananas. The checks aims disease, when the plant is at least 10 sheets at the time of daeometria and six at the time dela harvest. Systemic disease is destructive, more severely and more aggressive that can affect a crop of Musa, including plantains, bananas and heliconias.
It is produced by the bacterium Ralstonia solanacearum, from the Solanaceae such as tomato, pepper and potato, is transmitted firestal vectors and on the ground. Internal symptoms are manifested in the corm and affects all vascular lesions occurring as spots and points with color ranging from yellow to dark brown. This insect can be easily identified by its dark brown color and the size of 1 cm. This insect makes Holometabola or complete metamorphosis.
The only damaging is the larval stage. The larvae bore into the mouths chewing banana corm around inside and stop circulation to the rest of the plant as nutrients absorbed by roots. Sometimes also drilled areas around the stem, but usually do not penetrate deeply into it, at least in growing plants.
In severely attacked plants, the central leaves sprout, grow slowly, the stem grows long and small diameter, no yellowing of the leaves, the fruits are not fully developed and maturity is premature.
There daslmetria be no fruiting and rapid aging of the plant. Plants perforated yams, despite showing no evidence of the attack, weaken in their support, so much so, that the wind easily tomb is, fall under the weight of the bunch, the level break floor, where it is noted that the rupture zone is drilled from one foretal to another by irregular tunnels which are insect larvae.
The description of this insect is in the cultivatio n of cassava, here only explain the damage caused in the banana. If you attack is strong, the fruit’s skin becomes rough and cracked, and the flesh becomes dry in texture. When the attack is mild, it affects his presence, but does not cause changes in eating qualities. The attack of thrips can be observed when the dasometrai is in bloom. History of the timber. Wood is a natural organic material with a cellular structure, wood is called the set of tissues that form the dasoetria, roots and branches of woody plants, excluding the crust.
These are classified in wood of conifers and hardwood timber. The hardwoods are woody dicotyledonous angiosperms belonging to oak, elm, oak, etc. Wood is not a homogeneous dasometriw, but consists of a set of specialized cells in tissues that perform essential functions of the dasonetria This heterogeneity in the timber is reflected in their physical and mechanical properties.
The wood can be hard and soft as the tree from which they are obtained. The wood of deciduous trees is called hardwood and softwood Softwood is called, regardless of its hardness. Thus many softwoods are harder than hardwoods calls. Hardwoods have long continuous vessels dasommetria the trunk and not soft, soil extracted elements are transported from cell to cell. The nodes are areas of the trunk in which the base is formed of a branch.
When the dasomrtria is cut into boards knots are discontinuities or irregularities that appear circular in dassometria. These tend to weaken the tables and leave holes, so it is not required, unless resulting colorful for decorative use, covering or furniture.
The mechanical properties include the structural possibilities of the wood, it must take into account the strength, hardness, stiffness and density. The timber has the following mechanical properties: The resistance depends on how dry the wood is and the direction it is cut with respect to the grain.
The wood is always much stronger when cut in the direction of the grain, which is why the tables and other objects like poles and handles are cut well. The high compression strength is needed for building foundations and brackets.
The flexural strength is critical in the use of wooden structures, such daskmetria joists and studs all beams.
The oak for example, is very resistant to bending but weaker compression. Publicado por Yenny Fernanda Guarin Ramirez en
