Logic (from the Greek λογική, logikē)[1] has two senses; it is the study of modes of reasoning (those which are valid, and those which are fallacious)[2][3] as well as the use of valid reasoning. In the latter sense, logic is used in most intellectual activities, including philosophy and science, but in the first sense, it is primarily studied in the disciplines of philosophy, mathematics, semantics, and computer science. It examines general forms that arguments may take. In mathematics, it is the study of valid inferences within some formal language.[4] Logic is also studied in argumentation theory.[5]...

In the long-term perspective, success in achieving both consumer benefits
and increasing competitiveness depends on the quality of basic research. In
often highly specialised areas, research co-operation between scientists in
different member states is of utmost importance to achieve and maintain a
high level of quality. Within EU research activities, the transnational nature of
research should hence be dealt with by combining complementary expertise
in different countries, also leading to increased research productivity through
economies of scale....

The CAPRI model is an agricultural sector model covering the whole of EU-27, Norway and
Western Balkans at regional level (250 regions) and global agricultural markets at country or
country block level. CAPRI makes use of non linear mathematical programming tools to
maximise regional agricultural income with explicit consideration of the CAP instruments of
support in an open economy. CAPRI consists of a supply and market module which interact
iteratively. The supply module follows a ‘template approach’, where optimisation models can
be seen as representative farms maximising their profit by choosing the optimal composition
of outputs and inputs at...

The dairy premium introduced as an additional compensation, amounting to 24.49 €/tonnes
from 2006, can be supplemented by an increasing national top-up to a maximum of
11.01 €/tonne. In the EU-15, the dairy premium had to be integrated in the SPS by 2007 at the
latest. The EU-12 may only gradually introduce the direct payments starting with 25% of the
full payment level in the first year of introduction and ending with 100% in 2013. However,
they are allowed to provide national top-ups of a maximum 30%, which will have to be
successively reduced to zero. Regarding the implementation, most...

In India, rice, wheat and maize yields per hectare of land have increased three to
four fold between 1950 and 2010, mainly due to the adoption of improved agronomic
practices. Egg production now ranges between 310–320 per annum per bird. Similarly,
feed conversion efficiency in broilers is also at par with developed nations and Indian
poultry farmers are now more conscious of the need to increase profits by cutting costs
and improving productivity. Balancing of nutrients in poultry rations along with improved
mineral supplementation has led to this improved productivity. However, the perfor-
mance of ruminant livestock remains poor when compared...

The preparation of these guidelines began in 2008 under the supervision of Badi Besbes. Ini-
tial work was undertaken by Manuel Luque Cuesta. Workneh Ayalew produced a new draft
version of the guidelines, which was presented and discussed at workshops held in Argen-
tina, Senegal and Italy. These workshops were attended by 100 scientists, technicians and
policy-makers. A revised and updated draft was prepared by Badi Besbes, Workneh Ayalew
and Dafydd Pilling. Text boxes were provided by Luis Iñiguez and Evangelina Rodero Serrano.
The illustrations were prepared by Antje Weyhe. FAO would like to express its thanks to all
these individuals and...

Phenotypic characterization activities are technically and logistically challenging. Ensur-
ing that they are well targeted (collect data that are important to the country’s priority
AnGR- and livestock-development activities) and are carried out in an efficient and cost-
effective manner requires thorough planning and careful implementation. Valid compari-
sons among livestock breeds or populations, whether nationally or internationally, require
the development and use of standard practices and formats for describing their character-
istics. Such standards and protocols are also needed for assessing requests for the recogni-
tion of new breeds. The Global Plan of Action calls for the development of “international
technical standards and protocols for...

Dairies are required to have an NMP to protect water quality from livestock nutrient
discharges. Each basic function of the operation, production, collection, storage, transfer,
treatment and field application is covered by the plan. The basis for nutrient management
is sound agronomic use of solid and liquid manure. The Livestock Nutrient Management
Program has inspectors that routinely inspect dairies for compliance with their nutrient
management plans and preventing any discharges to surface and ground water....

Animal Identification is a national program to identify animals and track their movement
between premises. The information is used by Animal Health Officials to manage disease.
The goal is to be able to identify where affected animals have been within 48 hours of
confirmation of a disease outbreak or other animal health event.
WSDA began voluntary Premise Registration in January 2005. Knowing the locations of
animal premises is vital to Animal Health Officials when they are managing an incident.
A unique premise number is assigned to a location permanently. A premise number may
be requested by the landowner, the producer using the land, or the person...

All ground water sources should be
located a safe distance from sources of
contamination. In cases where sources are
severely limited; however, a ground water
aquifer that might become contaminated
may be considered for a water supply, if
treatment is provided. After a decision has
been made to locate a water source in an
area, it is necessary to determine the
distance the source should be placed from
the origin of contamination and the direction
of water movement. A determination of a
safe distance is based on specific local
factors described in the section on Sanitary
Survey.
Because many factors affect the
determination of safe distances between
ground water supplies and sources of
pollution, it...

The importance of a sanitary survey
of water sources cannot be overemphasized.
With a new supply, the sani tary survey
should be made in conjunction with the
collection of initial engineering data,
covering the development of a given source
and its capacity to meet existing and future
needs. The sanitary survey should include
the detection of all health hazards and the
assessment of their present and future
importance. Persons trained and competent
in public health engineering and the
epidemiology of waterborne diseases should
conduct the sanitary survey. In the case of
an existing supply, the sanitary survey
should be made at a frequency compatible
with the control of the health hazards and
the maintenance...

As a milk trader, you are aware that no other food
gets spoilt more easily than milk. Just as people like
milk for its nutritive value, bacteria that cause milk
spoilage also do. This guide is designed to help you
learn how to reduce the losses caused by spoilage to
allow you to increase your profits. The guide has been
put together with the participation of a pilot group of
small-scale raw milk traders in various parts of Kenya
to ensure that the material and methods suggested
are relevant, simple and practical, thus making them
directly applicable within your circumstances.
Improving your image as a quality milk trader should
ensure customer...

All these factors relate to milk spoilage. Traders are aware of most
of the causes and effects of milk spoilage. The relationship between
the traders and various stakeholders in milk marketing, whether
positive (e.g. provision of training) or negative (e.g. arrests) also
has an influence on their business and the quality of milk that
they sell. In a formal training session, the trainer can discuss more
examples of these relationships.

Milk from the udder of a healthy cow contains very few bacteria.
Poor hygiene introduces additional bacteria that make the milk
spoil quickly. To ensure that the milk remains fresh for a longer
time it is necessary to practice good hygiene. Good hygiene needs
to be observed at all stages of milk production, handling and
marketing. Therefore you need to advise the farmer on hygienic
milk production and handling after milking.

Trypanosomiasis, usually caused in camels by the protozoan Trypanosoma
evansi, is a major clinical disease and cause of economic loss. Unlike other
trypanosome species, T. evansi does not have to undergo part of its life
cycle in tsetse flies and it is transmitted mechanically by other biting flies.
These flies are usually of the tabanid group, mainly of the genus Tabanus,
but some so called stable flies of the genus Stomoxys, also transmit the
disease. In some of East African countries, the major tabanid vectors are
Philoliche zonata and P. magretti. ...

It is spread mainly by bites of infected animals. The virus present
in their saliva is inoculated in the bite trauma. Foxes are the main reservoir
of the disease. Camels can be infected by dog or fox bites, but the chances
of spread from camel to man appear to be small. Nevertheless, camel bites
in endemic (prevalent in a population or geographical areas at all times)
areas should be regarded potentially dangerous, especially if the animal is
showing signs of unusual behaviour at the time of bite or does so within
next 7 to 10 days (signs such as...

The major symptom of the acute form of the disease is severe anaemia.
However, in camels the disease due to T. evansi is usually chronic. This is
typically shown in slow weight loss, intermittent high fever, general
muscular weakness, especially in hind quarters, pale mucous membranes
and collection of fluid, especially in the abdominal region. Packed cell
volumes of blood plasma are usually 18-20% in infected animals compared
to an average of 30% (range 24-42%) in healthy ones. In more severe cases,
late term abortions and premature births of calves are very common in
pregnant animals, resulting also...

Eggs deposited by female mites in the horny outer layer of the skin undergo
three development stages (larvae, nymphs and adults) in about 17 to 21
days. The adult mites mechanically damage the skin of the host by making
minute burrows. Allergic reaction is shown to mite saliva and faeces
usually followed by secondary infection. Intense pruritis evolving small
vesicles and inflammatory reaction of the skin characterize the beginning of
the disease. Pruritis is severe and affected animals resort to extensive
rubbing and scratching. Affected areas show loss of hair and become moist
and suppurative. Fully developed mange...

At very high temperatures and constant heat loads even camels need to dissipate heat.
Many mammals achieve evaporative cooling through an increased respiratory rate rather
than by sweating. Respiratory cooling is relatively more expensive in water than is
sweating since faster respiration rates result in more energy being used. Normal
respiratory rates in camels are in the range of 6 to 11 breaths/min. (average 8) in the
Sahara. Under heat stress these increase to levels of 8 to 18 (average 16). Such low
respiration rates do not result in significantly increased evaporation. ...

A reduced water supply can be tolerated by a number of species of desert-adapted
animals and under these conditions its use becomes more efficient. Efficiency of use and
dehydration tolerance vary among species. Among domestic animals kept under the same
conditions, cattle lose water three times faster than camels (equivalent to 6.1% of body
weight per day at day/night temperatures of 40°C/25°C) and sheep two to two and a half
times faster (4 to 5% of body weight). Bedouin goats are capable of sustaining reductions
in body weight up to 35% but lose water much more rapidly than camels....

Rehydration consists not only of the ingestion of water but also of its absorption and
distribution throughout the body tissues. Because of large buffering capacity of their
alimentary tract, ruminants are able to drink large quantities of water in a very short time
after a period of privation. Animals without this capacity are rarely able to take all their
requirements in one short session, mainly due to the problems associated with
haemolysis. Some non-ruminants are, however, capable of rapid drinking, including dogs
and donkeys. Even amongst the group of ruminants, which drinks rapidly, the camel is
peculiar in...

The dromedary’s water intake is through drinking and the water in the feed. The need for
drinking depends on environmental temperature and humidity and the water content of
the feed. Under range conditions if water is readily available, camels may drink daily or
may not for several days. The main water losses are from evaporative cooling of the skin,
in urine and faeces, and even in these functions the conservation of water can be very
efficient. During exercise physiology studies, obvious sweating was not observed. It was
concluded that the main cooling mechanism was from respiratory losses. The
experiments were...

The summer/winter difference in plasma volume may be related to the regularly observed
summer fall in red blood cell values and total protein. In a fully dehydrated camel with
65% body water, alimentary water has been reported as 12%, which is similar to the
figure for tropical cattle. The total water content of the camel is considerably greater in
hot dry weather (up to 75%) than in cooler periods (down to 50%), which indicates its
physiological water conserving capability. It is well established that the glandular sac
area in the rumen secretes water into the alimentary compartment. This...

In the past it has been postulated that the metabolism of hump fat could supply water to
the fluid compartments when the camel is water deprived. While water is a by-product of
carbohydrate and fat metabolism, it is now known that the act of gaining the oxygen
required would cause the loss of more water than would be gained. Also, cellular
metabolism creates heat and the camel’s survival strategy, especially during periods of
water deprivation, is to reduce metabolic rate and hence heat production and water loss.
Experimentally, camels have been water deprived until 30% of body weight has...

Some water moves through the skin of mammals by insensitive diffusion. Most of the
water, which passes through the skin, however, does so in the form of active sweating.
Larger mammals usually sweat to dissipate heat. Among the domestic species, both
camels and cattle have adopted this mechanism. A characteristic of the camel is that there
is no copious flow of sweat or obvious wetting of the hair. The evaporation takes place at
the surface of the skin and not at the extremities of the hair. The latent heat of
evaporation is therefore drawn from the skin rather than from...
