Medical Ultrasound (also known as Diagnostic Sonography or Ultrasonography) is a diagnostic imagingtechnique based on the application of ultrasound. It is used to see internal body structures such as tendons,muscles, joints, vessels and internal organs. Its aim is often to find a source of a disease or to exclude anypathology. The practice of examining pregnant women using ultrasound is called obstetric ultrasound, and is widely used.

I. INTRODUCTION The use of ducks in the Philippines began during Spanish rule, particularly along the coast of Laguna Bay, where the ducks naturally feed (Coligado, 1986). Now, duck production is a prosperous industry and a source of food and livelihoods. It is also a source of government revenue. In 2000, there were 9.2 million ducks in the Philippines, most of which were ducks; about 7 million (76%) of them were raised in the yard and 2.2 million (24%) were kept in commercial duck farms. Duck production now grows at a rate of 2.30% per year. The factors that promote the development of the local duck industry are: ducks are well adapted to the warm and humid environmental conditions in the Philippines; lakes, rivers, and vastly irrigated rice fields have abundant duck feed; Filipinos like duck eggs, especially duck products such as processed products. Embryonic eggs, lean eggs, and salted duck eggs. These products are also exported to Philippine contract worker-intensive regions such as Hong Kong, Singapore, Taiwan, Guam and the Middle East. The Philippines is still implementing a traditional system of duck egg production and processing. However, due to some factors, duck egg production and processing are gradually changing. This article will introduce the important aspects of the duck raising industry in the Philippines, focusing on the production and processing of duck eggs. Second, the egg duck ducks (Mallard ducks), also known as Pateros duck (Pateros duck or "itik") accounted for most of the Philippines ducks. The duck's feathers are black and gray but can also be seen with gray, white and silver feathers. This variation in feathers is related to the ancestry of imported ducks occasionally. The average egg production rate of this duck (first year of laying) was 57.80%, which was much lower than that of Khaki Campbell (82.19%) and Cherry Valley egg-type (78.50%). (PCARRD,). The fertility rate and hatchability of wild duck eggs were 80%-85% and 85%-90%, respectively. Wild ducks are well adapted to the local environment and management conditions. In addition, consumers generally prefer the taste of wild duck eggs. In order to increase the production of ducks and improve the performance of local ducks, many duck varieties/strains have been imported from other countries. In 1956, the Philippine government imported Cameron-Cambell duck eggs. The implementation of the duck distribution plan resulted in the distribution of this breed duck throughout the country. It is estimated that the Malard X Khaki Cambell hybrid duck accounts for 50% of the total amount of ducks in the Philippines (FFTC, 1991). These improvements have resulted in egg production rates of 65%-76% higher than local ducks (57.80%). The Indian Runner and Tsaiya Duck in Taiwan are still playing a minor role in the production of local duck eggs. Currently, the Cherry Valley duck has been the choice of private sector advocates to make a huge change in the duck industry. However, the following problems have not been successful. Hatchers do not like the light green cherry valley duck eggs. Cherry valley duck eggs have lower fertilization rate than wild ducks. People who eat balut like to see and eat embryonic eggs with black/brown embryos that are processed with wild ducks. They do not like cherry valleys. Duck Egg-Processed Embryonic Egg with White Feather Embryo (Datuin, 2000). The use of wild ducks instead of Cherry Valley drakes in ducks can solve some of these problems. The duck breeder will feed the young ducks or the ducks to be produced for use as back-up ducks. Most ducklings are produced in hatcheries, and hatcheries are also engaged in the production of embryonic eggs, while ducks to be opened are provided by professionally cultivated bred duck producers. One of the current concerns is the lack of an organized duck breeding program. The small duck farm that makes up the majority of duckers is the most affected. They feed poor quality ducks and have poor performance. Third, the production system adopts different production systems for duck rearing. The herding system is a traditional system used by small (less than 1,000) and medium (3,000) duck production units. This breeding system is practiced more in irrigated rice production areas. The main breeding and laying ducks are bred by the caretaker in the newly harvested rice fields during the day to look for food. Ducks are lapped in temporary shelters at night. When there is no feed in the area to feed, the ducks are driven to new places. The advantage of this system is that the initial investment and operating costs are low, and the breeder can obtain considerable profits. However, there are many problems with this system. The instability of the feed supply and the quality of the natural feed affect the growth and development of the duck. As the farmland is transformed into residential and industrial land, the grazing area continues to decrease. In addition, because the ducks feed on feed contaminated with herbicides and pesticides, the mortality rate increases. Due to the above problems, intensive production systems have gradually been accepted by many duck producers. This system provides ducks with a duck house and a balanced diet, but this system requires a lot of capital investment. About 70% to 80% of the duck farms, especially those in the rice-producing regions, mostly use semi-intensive production systems (De Dios, 1996). Ducks are kept in ducks but they can enter the courtyard or fields to obtain their own food. At the same time, feed ducks only natural feed or mixed feed. Production systems that combine duck production with crop and livestock production are also being implemented. The most common is the combination of rice-duck and rice-fish (tilapia)-duck production. Individual areas in the fields provide ducks with simple shelters. Grazing intensity is 60 ducks/3000 m2. Although supplementary feed is provided daily, ducks are free to feed in the field. The golden snail (Pomacea sp.) is a terrible pest in paddy fields and is abundant in the rice fields of the Philippines. Ducks feed on snails to control the number of snails. At the same time, ducks can also help eliminate harmful insects and weeds in rice fields. Feed and Feed Management There are a large number of snails, snails, clams, and small fish on the banks of lakes and rivers. Fallen grains, insects, cockroaches, and snails can be found in rice fields. These natural feeds are the main source of nutrition for grazing ducks. They can also be collected (eg snails) as a feed for ducks. At certain times of the year, these feed supplements are lacking and their nutritional quality is poor, thus affecting duck performance. The pollution and deposition of lakes, turning lakes into fish fences and misuse of pesticides in rice production can be a factor in these feed supply reductions. Ten years ago, commercial duck feed (grain feed) had entered the market. Its use simplifies the breeding of ducks and leads to the production of a duck egg that meets the requirements. At present, medium-sized duck farms and commercial duck farms are the main markets for this feed (Dela Cruz, 2002; personal communications). Due to the high price of pellet feed, no approval has been obtained for this feed in small duck farms (Catingan, 1989). In the market, ducklings and young chicks have not yet been supplied. Therefore, duck farms use commercially available chicken feed instead. Some duck farms use a combination of locally available feed ingredients (such as rice bran, inferior rice, corn, fish meal, etc.) to prepare a mixture for ducks. In traditional feeding methods, young chicks are fed 4-5 times a day for the first three weeks. Minced fish and shrimp are added to rice from the age of 5 days. The same feed is also fed during the rearing period. When the ducklings are strong enough, they are grazing in the rice fields for food. Grazing continues until the start of production and the entire production period. Some duck farms use commercial chicken powder to feed ducklings and bred ducks. In general, wet feeds are used to make it easier for ducks to feed these feeds. The use of natural feeds as supplementary feed for bred ducks and laying ducks is in practice. Due to the large amount and low cost, ordinary snails and golden snails are used for this purpose. This feed can successfully add up to 50% in broiler ducks and laying ducks' diets and can significantly reduce feed costs. In terms of health, the native wild ducks predominate in the duck population. These ducks are well adapted to local environmental conditions, thanks in part to their resistance to disease. Diseases such as duck cholera, salmonellosis, sepsis, coliform disease, botulism, aspergillosis and aflatoxin poisoning have been reported. Eye worms, intestinal flukes, aphids, tapeworms and lice have also been found. It is worth mentioning that the occurrence of diseases and parasites has not caused serious problems. Fifth, the processing of duck eggs Fresh duck eggs can be used directly as food, but most of the processing into Filipino favorite food. The most popular is the embryonic eggs (locally known as balut). Fertilize the fertilized eggs for 16-18 days and cook them. Embryo eggs are considered special foods. Recently, food formulations containing embryonic eggs have been proposed. Embryo eggs are processed using at least medium-sized duck eggs with good eggshells. The traditional method of making embryonic eggs is to put the selected 100-120 eggs into a large bag and incubate them with brown rice heated to 42°C. Candles were examined on day 7 and day 14 of incubation to determine eggs that were not fertilized and fertilized, and embryos died. It is also possible to use a motor incubator for hatching. However, embryonic egg processors prefer to use traditional methods because of the low cost and lack of power supply problems. In the case of candlelight, eggs that have not been fertilized and the embryo has died can be cooked. This egg is called penoy. Another kind of dish made of duck eggs is salted eggs. Salted eggs are also made from good quality duck eggs. The selected egg is wrapped in a clay-salt solution (4-5?1) for a period of 19 days. After 19 days, the eggs are washed and cooked on low heat. The salted eggs sink into boiling water and turn red. Current research shows that warming clay used to preserve duck eggs can improve product acceptability and shelf life. Salted duck eggs are a favorite breakfast for Filipinos. During the Christian Day, Filipino Catholics quit meat and a salted egg is very common. Salted eggs are also popular as a match for local or indigenous snacks. Embryo eggs and lean eggs are usually sold by street vendors, while salted eggs are sold in the market. In order to improve the nutritional quality, some aspects related to management and storage need to be improved. VI. Conclusion The production and processing of duck eggs constitute the main part of the duck raising industry in the Philippines. The current duck industry needs improvement. In order to achieve the goal of improving the duck industry, the government and the private sector must work together. In order to reliably supply high quality ducks, breeding programs need to be developed. The breeding program must not only consider increasing productivity but also consider the degree of satisfaction of the product (eg embryonic eggs). The reduction in the availability of natural feeds requires feed substitutes, better feeding management and further understanding of the nutritional needs of ducks under different feeding and management conditions. The quality and shelf life of processed products should be improved by improving processing methods, management and storage. An industry expert once expressed the view that immediate action must be taken to save the industry, such as producers of duck eggs, from being replaced by other countries that can supply quality and cheap processed duck eggs. Because this processed product is delicious for Filipinos, this view is considered superfluous. However, if you are complacent about the status quo of the industry, it may lead to the realization of the above prediction.
