2. New means of combating and controlling these plagues and diseases are constantly being perfected,

The Third Inter-American Conference on Agriculture

Resolves:

To recommend to the governments of the American nations:

1. The periodic review, at stated intervals, of all quarantines and regulations prohibiting or restricting the entry of plants and vegetable and animal products, with the view of determining whether the biological risks responsible for the issuance of such quarantines or regulations still exist.

2. The determination of whether new methods of treatment have been perfected which might be employed to better advantage in safeguarding against the entrance of insect pests and diseases which prompted such exclusion or restriction.

XXXIII. INTER-AMERICAN COLLABORATION

WHEREAS:

1. Inter-American collaboration established between various countries of America and certain agencies of the Government of the United States of America, notably the Institute of Inter-American Affairs and the United States Department of Agriculture, has been beneficial:

(a) in promoting the production of food;

(b) in facilitating technicians and new agricultural techniques; (c) in furthering technical education and development by the interchange of students through fellowships;

(d) in facilitating the improvement of crops through the importation and exchange of seeds and selected varieties;

The Third Inter-American Conference on Agriculture

Resolves: To recommend that the Government of the United States of America, in agreement with the governments of the other American countries, take into consideration the best way to continue promoting such collaboration, giving it as large an inter-American character as possible on the basis of the existing bilateral agreements and increasing the interchange and cooperation among the American republics.

XXXIV. ARCHEOLOGICAL STUDIES AND THEir Relation to KNOWLEDGE OF FOOD AND MEDICINAL PLANTS

WHEREAS:

1. The American Continent has been the center of origin of numerous species of food and medicinal plants, which constitute the most valuable contribution of the New World to civilization;

2. Archeological discoveries give evidence of the special attention which the American aborigine gave first to the discovery, and then to the domestication, cultivation and propagation of valuable food species, revealing thereby his exceptional aptitudes as a naturalist, botanist, geneticist, geologist, agronomist, and hydraulician, as he bent his energies in the cultivation of the land by means of soil conservation, establishment of irrigation systems and the intensive utilization of lands suitable for production;

3. Likewise, archeological discoveries show that the American aborigine was a food expert who not only selected, by patient effort, the plants which his immediate needs required, but also reached the point of developing appropriate methods for the conservation of his products, including dehydration leading both to the utilization of new nutritive qualities and to the more convenient and easier transportation thereof;

4. In addition to the food species, the American aborigine discovered and used the medicinal qualities of an appreciable quantity of native plants of the Continent, such as cinchona, coca, et cetera, which have contributed so notably to the advancement of medical science;

5. Present-day civilization has not yet taken advantage of all the botanical contribution which the American aborigine has bequeathed mankind for its sustenance and the preservation and recovery of its health, for which reason it is necessary to do everything possible to stimulate the investigation and encourage the distribution of plants which, furthermore, will contribute toward vitalizing the economy and industry of the American countries,

The Third Inter-American Conference on Agriculture

Resolves:

To recommend to the governments of the American countries:

1. The organization of archeological studies in order to obtain a scientific approach to the history of the agriculture of the American Continent, which will lead to a better knowledge and utilization of the numerous food and medicinal species native to the soil, so far not fully appreciated.

734618-47-9

2. The widest publicity concerning the food and medicinal properties of the aboriginal plants, favoring their intensive propagation in the collective effort for the well-being of all the peoples of the earth. 3. That the governments of the American countries which have developed the cultivation and industrialization of medicinal and aromatic plants adopt measures to increase these resources.

WHEREAS:

XXXV. IMPROVEMENT OF LIVESTOCK

1. A prosperous national livestock industry is of great importance to a nation's welfare;

2. The application of the modern scientific knowledge pertaining to animal breeding, feeding, and management, and to the prevention of parasitosis and diseases, is essential for providing efficiency in livestock production;

3. Technically trained personnel, schooled in the latest technological developments, are needed for solving important livestock problems;

4. The prompt and continuous exchange of technical information relating to improved livestock practices among American countries would result in mutual benefits to the countries,

The Third Inter-American Conference on Agriculture

Resolves:

1. To recommend that full advantage be taken of the educational facilities for the training of students and research workers in the field of livestock production and related activities;

2. That measures be adopted for prompt and orderly exchange of scientific knowledge pertaining to livestock.

XXXVI. NEED FOR THE IMPROVEMENT OF NATIVE OR REGIONAL TROPICAL AND SUBTROPICAL LIVESTOCK OF AMERICA

WHEREAS:

1. The zootechnic problem of improvement of livestock in subtropical and tropical regions depends upon, among other factors, the increase of early maturity in regional livestock and the adaptation of the improved products;

2. There exists, because of a slow process of natural selection, a great many native livestock perfectly adapted and acclimated;

3. It would be illogical to add the blood of perfected breeds which would transmit hereditarily their characteristics of early maturity, if we did not previously improve environmental conditions to take into account their most elementary requirements;

4. By making a directed selection of this regional livestock, a noticeable improvement will be achieved and its adaptability could be utilized for any of the zootechnic methods which may subsequently be applied;

5. Zootechnic studies of the said livestock, especially cattle, should be continued, with the aim of improving production;

The Third Inter-American Conference on Agriculture

Resolves:

1. To recommend to the American countries the selection of native or regional livestock in their respective zones in order to obtain local strains and, at the same time, improve environmental conditions by modern zootechnic methods recommended by experiment stations or other technical agencies;

2. That whenever, as a result of the above-mentioned research and experiment, there arises the advisability of introducing the blood of improved strains, such blood should come from individual animals with characteristics of preadaption that harmonize environmental conditions with the products obtained.

WHEREAS:

XXXVII. FEEDING OF DOMESTIC ANIMALS

1. A rational increase in the cattle industry is of vital importance for almost all of the American countries;

2. To attain this increase it is necessary to solve, among other problems, that of the production of balanced foods at low prices and in sufficient quantities to meet the needs of each country;

3. Forage crops are the important base of cattle feeding, The Third Inter-American Conference on Agriculture

Resolves:

To recommend to the governments of the American countries: 1. That they intensify the cultivation of the crops and other sources of raw materials necessary to produce balanced rations;

2. That those governments which cannot produce said raw materials economically reduce to the minimum the tariff charges on them;

3. That they facilitate widest interchange of information in all matters relating to the acclimatization and cultivation of forage plants for feeding domestic livestock.

XXXVIII. GENEALOGICAL REGISTRATION FOR ANIMALS

The Third Inter-American Conference on Agriculture

Resolves:

1. To recommend to the countries of America which have not

complied with paragraphs I and IV of Resolution XLIX of the Second Inter-American Conference on Agriculture, that they do so as soon as possible.

2. That standardization of registration systems and procedures, at order that animals registered in one country may be recognized with the same documentation in others, be accomplished in accordance with the standards agreed upon by the International Convention held at The Hague in 1936.

3. That the American nations study the problem of genealogical registration with regard to artificial insemination, in order that at the Fourth Inter-American Conference on Agriculture concrete plans may be submitted for regulating the registration of animals conceived through the use of artificial insemination.

XXXIX. POSSIBILITIES OF ARTIFICIAL INSEMINATION WHEREAS:

1. Experiments on and the practical application of artificial insemination on the various domestic species have been carried on for a number of years;

2. The results so far obtained are frankly encouraging, but in every case work has been done with fresh semen and on certain occasions operations have been carried on with preserved semen;

3. Experiments on methods of preservation for transportation are being carried on somewhat vigorously, since it is considered that it might broaden the possibilities of this modern zootechnic method of reproduction,

The Third Inter-American Conference on Agriculture

Resolves:

To recommend to the American governments:

1. That they intensify research on the preservation and transportation over long distances of semen and on technical methods employed in artificial insemination.

2. That they take steps with the corresponding authorities and with transportation companies in order to obtain preference for the transportation and delivery of the semen.
