2 ABSTRACT
2.1 Experiment design
A study of effect of using soya waste and energy feed sources in diets on growing
crossbred rabbits was conducted at household and laboratory of Animal Science Department of Soc Trang community college with three experiments (Exp.) Three experiments were completely randomized design with five treatments and 3 replications, with sixty crossbred rabbits for each Exp.1 and 3 but thirty crossbred rabbits for Exp.2 Two males and two females were allocated in an experimental unit The treatments of Exp.1 and Epx.2 were supplementation of soya waste at different levels of 0, 80, 160, 240 and 320g in the sweet potato basal diets While the treatments
of Exp 3 were supplementation of 29g broken rice (BR29), 35g paddy rice (PR35), 26g maize (M26), 35g molasses (Mo35), 27g dried cassava root slices (C27) in the diets based on soya waste and sweet potato Exp.1 was done on crossbred-rabbits at 7 weeks of age to evaluate feed intake, and growth performance Exp.2 was conducted
on crossbred-rabbits at 11 weeks of age to determine nutrient digestibility and nitrogen retention The third Exp used growing rabbits at 9 weeks of age
2.2 The result
The results of Exp.1 showed that the DM and CP intakes, growth rate (g/rabbit/day) were improved with increasing levels of soya waste in diets, and the highest results in SW240 and SW320 diets (P<0.05) The weights of carcass and lean meat were significantly higher in the soya waste diets (P<0.05) Profit per rabbit was the highest for the treatment of SW320 (22,100 VND/rabbit)
Trang 3Exp.2 indicated that the digestibility values of DM, OM, CP, NDF, ADF, N intake and
N retention increased with increasing levels of soya waste in the diets and the highest results were found in the SW320 diet (P<0.05)
The results of third Exp showed that the DM and OM intakes were higher in the L35 diet and lower in the KM27 diet but being not significantly different (P>0.05) Weight gain were not significantly different among treatments (P>0.05)
It was concluded that could be supplementation of soya waste in diets at level of 240 g/day for growing rabbits gave high growth performance and better economic returns There was efficient of using energy feed sources such as broken rice, paddy rice, maize, molasses, dried cassava root slices in the diets for growing rabbits

3 Reproductive Performance, Growth Rate, Carcass and Meat Quality of Crossbreds between F1(Landrace x Yorkshire) Sows and Landrace, Duroc and F1(Piétrain x Duroc) Boars
SUMMARY
A study was carried out at 3 pig farms in Hai Dương and Hưng Yên from 2008 to 2009
to evaluate reproductive performance, growth rate, carcass and meat quality of crossbred pigs resulted from F1 (Landrace x Yorkshire) sows bred with Landrace, Duroc or F1 (Piétrain x Duroc) boars Results showed that reproductive performances
of the three crossbreds were high (11.17, 11.25, and 11.45 borns/litter and 10.06, 10.05, and 10.15 weaned piglets/litter, respectively) These crossbreds had high growth rates and low feed conversion ratio (FCR) (728.09, 723.47, and 735.33 g/day,
Trang 4and 2.58, 2.52, and 2.48 kg feed/kg weight gain, respectively) Dressing and lean meat percentages of pigs resulted from F1 (Landrace x Yorkshire) mated with F1 (Piétrain
x Duroc) were higher than those from F1 (Landrace x Yorkshire) mated with Landrace and Duroc boars Drip loss, pH45, pH24 and colour of meat of the 3 crossbreds were normal It was therefore suggested to use crossbed boars F1 (Piétrain x Duroc) to mate with F1 (Landrace x Yorkshire) sows to obtain high performances of the crossbreds

4 Effects of Artichoke Products on Oxytetracyclines Elimination in Chicken
SUMMARY
Oxytetracyclines were added with doses of 100 and 500 ppm and fed to broilers in consecutive five and seven days; the above mentioned courses with the supplement of 10% artichoke products (dose of 6 ml/1 liter drinking water) were also fed to broilers
in order to investigate residues of oxytetracyclines and the effects of artichoke products on their elimination Results showed that residues were found at both doses
of oxytetracyclines (without artichoke products) after 1 - 5 and 7 days of antibiotic withdrawal, respectively The residues of oxytetracyclines were higher at the dose of
500 ppm in comparison with the 100 ppm in kidney, liver, breast and thigh fillet The residue levels were reduced with time There was no difference in the antibiotic elimination time between two courses of antibiotic supplements, i.e 5 and 7 days On the other hand, the supplement of 10% artichoke products at the dose of 500 ppm oxytetracyclines demonstrated the reduce of residues of oxytetracyclines in the above samples and the elimination time reduced to 5 days in compare with 7 days in the
Trang 5control group The residue levels of oxytetracyclines were lower at the dose of 100 ppm oxytetracyclines, however, there was no difference in the elimination time

Trang 6Unit 3: ANIMAL BODY
READING
The animal body is made up of millions of cells which have all developed from one cell by a process of division during which they gradually become more specialized The
specialized cells group together to form the various tissues of the body There are four basic types of tissue in the animal body: epithelium, connective tissue, muscular tissue and nervous tissue From these tissues different organs or viscera are formed The organs are the well defined parts of the animal which perform particular functions Groups of organs having a particular common function are referred to as organs systems
In general, the body can be divided into the following regions: the head; the neck; the trunk, which is further subdivided into two parts: the thorax and the abdomen (The two parts are separated from each other by an arched partition called diaphragm); the four limbs
The viscera of the body include:
- The digestive organs are concerned with the nutrition of the animal This function includes the prehension of food, its mastication, digestion, and absorption, and the initial storage of the nutrients released during digestion The digestive organs also provide for the expulsion of the unabsorbed portion of the food, and those substances that are added to the digestive tract by its large accessory glands
- The respiratory organs provide for the exchange of gases between the blood and the atmosphere, and produce the voice
Trang 7- The urinary organs, notably the kidneys, eliminate fluid wasted and foreign
substances from the blood, and regulate the water and salt metabolism of the body
- The genital organs are concerned with reproduction Except for the production of the
germ cells, the male and female organs have different functions to perform and
consequently differ markedly in their morphology These four organ systems are
closely related functionally to the blood vascular and lymphatic systems, to the
nervous system which controls their functioning, and to the system of endocrine
glands
Most of the viscera are contained in the large body cavities of the trunk Some of them,
however, are embedded in the tissues of the head, neck, and in the caudal part of the
pelvis, where special cavities for them do not develop The viscera occupying the body
cavities are covered with the same serous membrane that lines the cavities, and are
separated from one another and from the walls of the cavities, which allows them a
certain amount of mobility All viscera have either a lumen or an internal duct system
with which they communicate either directly or indirectly with the outside, through the
mouth, nose, anus, or the urogenital openings, as the case maybe
