have learned from the passage http://www.ebook.edu.vn Bài giảng tiếng anh chuyên ngành chăn nuôi thú y Lesson OVER VIEW OF ANIMAL SCIENCES I Reading comprehension: Animal agriculture is a significant portion of agriculture production Related research, education and extension activities are continually changing to address new challenges and opportunities brought about by rapidly advancing technologies, evolving consumer demand, and the need to make positive contributions to environmental, human, and animal health Efficient, science-based animal agriculture translates into affordable and high-quality food for the consumer Researchers collaborate with industry and other interested parties to develop and disseminate knowledge and methods to improve agriculturally relevant animal systems Animal Breeding, Genetics & Genomics: Animal protein is essential in meeting escalating nutritional needs around the world Animal Breeding, Genetics & Genomics research focuses on desirable genetic animal traits that have revolutionized poultry, livestock, and fish production These genetic traits include animals that are leaner; have increased disease resistance; or excel in growth rate or the production of eggs, meat, milk, wool, or mohair The natural efficiency of an animal to use http://www.ebook.edu.vn Bài giảng tiếng anh chuyên ngành chăn nuôi thú y nutrients in its feed could affect the nutrients in the manure and thus affect the environment Animal Nutrition and Growth: Inefficient nutrient intake by animals is financially and environmentally costly in animal operations from livestock farms to fish farms It not only hurts animal growth, health, and well-being, but it may also affect the safety and quality of the food products It may result in excess nutrients polluting the environment in the form of odors or ground water contamination The primary objective of the Animal Growth and Nutrition Program is to discover the nutritional, biological, and genetic factors underlying: • Normal animal growth • Nutrient digestion and efficiency • Metabolism • Lactation • Muscle and bone development Animal Products: Americans buy approximately $100 billion of animal products at the farm gate, and several times that amount at retail each year These products include meat and meat products, poultry products (meat and eggs), fish, shellfish, dairy products (milk and cheese), and non-food products such as fiber (wool, mohair, cashmere, and leather) The quality and safety of animal products prior to harvest are influenced by genetics, nutrition, and management systems After harvest they are affected by handling, processing, storage, and marketing practices Animal Reproduction: Reproductive efficiency is the major factor affecting profitability in many livestock production systems For example, the fertility of domestic ruminants (cattle and sheep), even under optimal conditions, is only about 50 percent Inefficient reproduction may be caused by numerous factors, including: • Increased genetic selection for meat or milk production traits http://www.ebook.edu.vn Bài giảng tiếng anh chuyên ngành chăn nuôi thú y • Early embryonic and fetal loss • Failure to reach puberty at an optimum age or an inability of young females to conceive early in the breeding season • Environmental stressors such as temperature extremes or changes in photoperiod (day and night cycle) • Production of sperm with a low potential for fertilization • Limited sex drive Animal Well-being: Evaluating farm animal well-being is a challenge to the animal food industry and scientific communities Scientists study how to accurately measure an animal’s state of comfort and well-being For example, scientists study animals in different environmental conditions that vary in temperature, humidity, amount of daylight, bedding, size and shape of living quarters, and the number of other animals in the environment They also work to understand how animals react both behaviorally and biologically in stressful situations, such as in transport, or when animals must be restrained, such as during a medical evaluation or treatment These understandings are important to those who work with animals as pets, livestock, or wildlife to ensure the safety and well-being of both animals and humans as they interact II Vocabulary: Agriculture: (n) [ ]: Nông nghiệp Production:

giảng tiếng anh chuyên ngành chăn nuôi thú y Lesson 10 INTRODUCTION ON AQUACULTURE AND FISHERIES I Reading comprehension The word “aquaculture”, though used rather winderly for over a decade to denote all forms of culture of aquatic animals and plants in fresh, brackish and marine environments, is still used by mary in a more restrictive sense For some, it means aquatic culture other than fish farming or fish husbandry, whereas others understand it as aquatic farming other than mariculture It is also sometimes used as a synonym for mariculture However, the term aquaculture is sufficiently expressive and allinclusive It only needs a clarification that it does not include the culture of essentially terrestrial plants(as, for example, in hydroponics) or of basically terrestrial animals However, when it needs to be used to denote (i) the type of culture techniques or systems ( pond culture, raceway culture, cage culture, raft culture); (ii) the type of organism cultured(e.g fish culture or fish husbandry, oyster, mussel, shrimp or seaweed culture); (iii) the enviroment in which the culture is done (e.g 49 http://www.ebook.edu.vn Bài giảng tiếng anh chuyên ngành chăn nuôi thú y fresh water, brachkish water, salt water or marine aquaculture or mariculture); or ( iv) a specific character of the enviroment used for culture (e.g cold-water or warm-water aquaculture, upland, lowland, inland, coastal, estuarine), the use of restricitive terms would probable be more appropriate While aquaculture is generally considered as a part of fisheries science, there is now a tendency to denote the distnction between the two by using the term “fisheries and aquaculture”, because of some the basic diffirences in development and management Author: Pillay, 1990 In Aquaculture;

mariculture) Representatives from other phyla could become important to aquaculture in the future IV Assignment Uses all possible information above to write a short text (preferably 50 words) to summarize your perception about general aquaculture and fisheries Lesson 11 FISH NUTRITION AND AQUACULTURE WASTE MANAGEMENT I Reading comprehension Aquaculture activities can have a significant effect on the health and quality of receiving waters Changes in oxygen, temperature, pH, and the addition of metals, drugs, suspended solids, ammonia, organic nitrogen, and phosphorus are often measurable downstream from hatcheries The impact of farm discharges on the receiving waters depends, in part, on the level of nutrients already present In the North of Vietnam, where most lakes and streams are already nutrien tenriched (mesotrophic or eutrophic), the addition of farm wastes is usually considered detrimental Phosphorus (P) and nitrogen (N) in farm wastes primarily originate from feeds and are of greatest concern due to their role in nutrient enrichment (eutrophication) Eutrophication is the artificial enrichment of waters which often results in blooms of noxious algae or excessive growth of higher plants 52 http://www.ebook.edu.vn Bài giảng tiếng anh chuyên ngành chăn nuôi thú y When the plants die, the decaying organic material can deplete water of oxygen to a degree detrimental to other aquatic organisms I Read the following passages and match each heading with one proper passage: Estimating Nutrient Loading, Feeding, Feed Selection Floating feeds should be used whenever possible Floating feeds allow the aquaculturist to monitor fish feeding activity In addition, floating feeds may be more waterstable than some sinking pellets However, sinking feeds are generally less expensive than floating feeds and some fish species may be reluctant to actively feed at the surface It is good practice to feed the largest pellet size which is acceptable to the fish Fish expend less energy during feeding if their feed needs are met by fewer, larger pellets Larger pellets also have a smaller surface-to-volume ratio than smaller pellets which reduces the rate and amount of nutrients that leach into the water before the pellets are consumed Feed ‘dust’ and particles too small to be consumed by the fish should be screened out prior to feeding A high quality feed will contain < 1% fines Poor feeding management can be an important source of farm wastes Even perfectly formulated feeds will result in excess effluent nutrients if fish are over fed Most feed manufacturers suggest feeding rates for their different feeds based on fish size and water temperature If given the opportunity, fish generally will consume more feed than they can use efficiently For this reason, demand feeders should be avoided except under special circumstances such as feed training If a demand feeder must be used, the amount of feed provided daily should be limited to feeding table values or established daily feeding rates for the farm Feeding schedules should be designed to account for fish behavior Factors that affect of active feeding, such as light sensitivity or time of day, may influence feeding efficiency The amount of N and P released in farm effluents is often estimated using water samples The concentration of nutrients in farm effluents fluctuates frequently due to management practices and nutrient interaction with the air, bacteria and algae, 53 http://www.ebook.edu.vn Bài giảng tiếng anh chuyên ngành chăn nuôi thú y and sediments Since water sampling is expensive, samples may not be tested often enough to accurately reflect farm nutrient discharges Alternately, N loading may be calculated based on fish weight gain Using this method, fish protein gain, based simply on weight gain, is mathematically translated into N gain Subtracting the amount of N gained by the fish from the amount of N fed results in an N loss estimate This simple calculation is possible because the amount of protein (or N) in a fish is directly related to its weight If fish are excessively fatty, N lost will be underestimated If final weights of individual fish are not similar or normally distributed about the mean, calculations must be made for subgroups of similarly sized fish Authors: Laurel J Ramseyer and Donald L Garling; Department of Fisheries

Vietnamese Lesson 12 CARP I Reading comprehension Carp is a common name for various freshwater fish of the family Cyprinidae, a very large group of fishes originally from Eurasia and Southeast Asia Some consider all cyprinid fishes carp and the family Cyprinidae itself is often known as the carp family In colloquial use, however, carp usually refers only to several larger cyprinid species such as common carp, crucian carp, grass carp, silver carp bighead carp Carp have long been an important food fish to humans, as well as popular ornamental fishes As a result, carp have been introduced to various locations, though with mixed results Ornamental carp 57 http://www.ebook.edu.vn Bài giảng tiếng anh chuyên ngành chăn nuôi thú y Carp, along with many of their cyprinid relatives, are popular ornamental aquarium and pond fish The two most notable ornamental carps are goldfish and koi Goldfish were kept as ornamental fish in China for hundreds of years before being introduced to Japan in the 15th century, and to Europe in the late 17th century The koi, a domesticated variety of common carp, also originated from China and spread widely in Japan The koi are historically a prevalent symbol in Japanese culture of good luck They are shown in competitive fish shows like those at the All-Japan exhibition They are also popular in other parts of the world as pond fish Goldfish and koi have advantages over most ornamental fishes, as they are tolerant of cold (they can survive in temperatures as low as degrees Celsius), and can survive at low oxygen levels Carp as pests Carp have been introduced, often illegally, in many countries In the USA they were introduced by the US government as a food source around the turn of the century in one of the largest and most successful stocking efforts in history In Australia there is enormous anecdotal and mounting scientific evidence that introduced carp are the cause of permanent turbidity and loss of submerged vegetation in the Murray-Darling river system, with severe consequences for river ecosystems, water quality and native fish species Efforts to eradicate a small colony from Tasmania's Lake Crescent without chemicals have been successful; however, the lengthy, expensive and intensive undertaking is an example of both the possibility and difficulty of safely removing the species once it is established Source:
