(1) EFFECTS OF DIFFERENT DIETARY LEVELS OF DISTILLER’S DRIED GRAINS WITH SOLUBLES ON THE LAYING PERFORMANCE AND BLOOD CHARACTERISTICS IN LAYERS
Results indicated that feeding the diet with 12% or lower DDGS will not affect the laying performance of laying hens.
(2) EFFECTS OF DIFFERENT DIETARY LEVELS OF COPPER AND ZINC ON THE LAYING PERFORMANCE AND EGG SHELL QUALITY IN LEGHORN LAYERS
Dietary provision of Cu 9 mg/kg and Zn 90 mg/kg were required for good laying performance and egg shell quality of Leghorn layers. The concentration of copper and zinc in excreta can meet the national copper and zinc standard when the hens were fed the diet containing Cu 9 mg/kg and Zn 90 mg/kg . Another experimental result showed that the reduction of dietary Cu to 10 mg/kg and Zn 60 mg/kg and added the phytase (500 U/kg) or provided with 5 mg/kg organic Cu and 30 mg/kg Zn will not affect laying performances and a better shell quality was found.
(3) EFFECTS OF DIETARY ELECTROLYTES AND VITAMIN C SUPPLEMENTATION ON THE PHYSICAL RESPONSES AND BLOOD BIOCHEMICAL VALUE OF COCKS DURING THE CYCLIC HEAT STRESS
The dietary electrolytes and vitamin C supplementation can significantly increase the blood pCO2, sodium, cations and HCO3- ion concentrations of the cocks. Besides, cocks fed provided with electrolytes or vitamin C in diets had significantly decreased the uric acid and alkaline phosphatase
(4) ESTABLISHING THE CRUDE PROTEIN AND METABOLIZABLE ENERGY REQUIREMENTS OF BROWN TSAIYA DUCKS DURING LAYING PERIOD
Diet containing 22％ crude protein and 2,750 kcal/kg metabolizable energy had highest laying performance for brown Tasiya ducks.
(5) EFFECTS OF USING LARGE-GROUND OYSTER SHELL TO REPLACE TWO-THIRD OF LIMESTONE IN DIET FOR BROWN TSAIYA DUCKS ON LAYING PERFORMANCE
The two-third of limestone in diet of Brown Tasiya duck was replaced by large ground oyster shell didn't have adverse effects on laying performance.
(6) EFFECTS OF DIETS ON PRODUCTIVE PERFORMANCE AND TRAITS OF FRESH EGGS AND ALKALIZED EGGS IN BROWN TSAIYA DUCKS DURING SUMMER SEASON
Using commercial laying duck’s diet would be a better choice when production cost, laying performance and egg traits were considered. Adjustment in nutrient concentration, amino acid composition or the addition of protease do not have positive effect on laying performance.
(7) YOLK COLOR IMPROVEMENT BY NATURAL PIGMENTS
Consumers in Taiwan prefer the eggs with dark color yolk. Results showed that feeding alfalfa and napier grass to laying hen improve the yolk coloration and the egg production traits.
(8) INHIBITING THE INCIDENCE OF ANGEL WING IN GEESE BY FEED FORMULATION
In Taiwan, Angel wing occurs mostly during the ages from 6 to 14 weeks post hatching in White Roman goose. In the experiment , feeding birds the diet with low nutrition concentration may result in lower occurrence and incidence of angel wing(IAW). a feed formulation has been developed to effectively reduce more than 10% IAW.
(9) THE EFFECTS OF SUN-CURED PEANUT VINE DIET ON THE GROWTH PERFORMANCE OF DOMESTIC GEESE FROM 9 TO 13 WEEKS OF AGE
The sun-cured peanut vine was an useful roughage for the growth of domestic geese age from 9 to 13 wks although it has high fiber content.
