Influence of Acrida cinerea Replacing Peru Fish Meal on Growth Performance of Broiler Chickens

Abstract: The nutritional value of Acrida cinerea were analysed.The influence of Acrida cinerea replacing Peru fish meal on growth performance of broiler chickens was investigated The results showed that feed replacing 20% and 40% Peru fish meal with Acrida cinenea for broiler chickens in growth rate and feed consumption tended to be similar to that resulting from feeding a normal contain diet The study suggests that the Acrida cinerea may replace Peru fish meal partly

Comparative Analysis of Contents of Hydrolysis Amino Acid of Different Part in Northeast Sikadeer Velvet

Abstract: In this study, hydrolysis amino acid contents of northeast sika deer velvet wax slices,powder slices,blood slices and bone slices were determined. Total hydrolysis amino acid contents of above slices were different significantly (P0.01).

Comparison of Two Overwintering Ways for Chinese Alligator in Captivity

Abstract: Overwintering has been a major problem since Chinese alligator was introduced to Northern China. From 1996 to 1999, two ways for overwintering of the reptile, ie. hibernation and non hibernation under controlled temperature, were tested. The results indicated that non hibernation has advantages over hibernation under Northern China area where the natural environmental conditions for Chinese alligator overwintering is difficult to simulated.

Study on the Ecological Adaptability of Forest Frog Rana chensinensis Moved to the South

Abstract: The phenomenons such as growth slowly, high death rate, the change of behavior and the growth of young frog have been studied within the feeding population of the forest frog moved to the South. The variation of ecological factors in the South which become forced actor to the animal have made some effect on frog's dormancy and breeding. Among the ecological factors, food supply, light cycle and temperature of environment are the most determined factors. In addition some technological improvement have been suggested for the forest frog's feeding practice.

Study on the Ecological Breeding Technology of Mud eel

Abstract: This article briefly introduce the breeding habits of mud eel in nature environment. And according to the nature breeding habits of mud eel, they were induced by LRH-A and DOM, causing them mating in the imitative nature ecosystem environment. The total 335,000 hatchlings were obtained at one time. The method are helpful for development of the large-scale half-artificial breeding of mud eel.

Determination of Nutrient Apparent Digestibility and Discussion of Determination Method in ostrich

Abstract: Three 15 months age ostriches(1♂2♀)were used to determined apparent digestibility of nutrients in this experiment. The result showed that apparent digestibility of DM ,CP, CF, EE, NFE and total P were 55.9%±0.21%, 68.5%±0.22%, 57.4%±1.21%, 58.8%±1.35%, 75.3%± 0.62% and 55.2±1.10% respectively. The digestibility of Ca was not measured because there was lots of sand in alimentary tract. The proper determination method of digestibility in ostrich was discussed as well.

Operating Instruction of Fox Artificial Insemination

Abstract: An operating instruction for fox artificial insemination (AI) was presented based on the experience obtained from fox AI practice through last several years combined with the knowledge of fox AI.

Number of Drones Mated with Queen Determined Using RAPD Analysis

Abstract: Virgin queen of Apis mellifera ligustica was artificially inseminated with semen from drones of Apis mellifera carnica and Apis mellifera caucasia. Eleven primers were used for radom amplified polymorphic DNA analysis. The number of drones mated with the queen was calculated based on the average genetic similar coefficient between drone individuals according to RAPD analysis. The results indicated that RAPD analysis is a effective method in determining the number of drone mated with a queen.
