Reproductive performance and EGG quality traits of crossbreeding between two strains of snails

Abstract: espanolSe emplearon caracoles Archachatina marginata saturalis de dos lineas: piel negra y piel blanca. A partir de 45 caracoles de cada tipo distribuidos en tres grupos segun su peso vivo: I: 40-44 g; II: 45-49 g y III: 50-54 g, fueron seleccionados aleatoriamente 10 caracoles de carne negra de cada grupo y fueron cruzados individualmente durante 12 semanas con otros 10 caracoles de carne blanca de cada grupo. El cruce entre ambos tipos de caracoles es posible y sus parametros reproductivos son similares a los de lineas puras. El peso vivo no afecto a ninguno de los parametros reproductivos evaluados EnglishForty five snails (Archachatina marginata saturalis ) of each strain (black and white skinned) were distributed into three groups on the basis of body weight: I: 40-44 g; II: 45-49 g and III: 50-54 g. Ten black skinned snails from each group were randomly selected and were individually mated with other ten white skinned snails from each group for twelve weeks. Crossing between the two types of snails is possible and its reproductive parameters are similar to those of pure lines. The body weight did not affect any of reproductive parameters evaluated.

Comparative evaluation of reproductive performance and some egg quality parameters of black and white skinned snails.

Abstract: One hundred sexually matured snails, fifty each of the black skinned and white skinned ectotypes were used in the evaluation of reproductive performance and egg quality traits in a study that lasted for eighty-four days. The reproductive performance traits measured included clutch size (number of eggs laid per clutch), incubation period (days) of eggs, percent hatchability, and percent mortality and survivability, while the egg quality traits evaluated included egg weight and length. Results obtained showed significant differences at different levels among parameters measured in the two ectotypes of snails studied. The results of reproductive traits showed that mean clutch sizes were 5 and 4 for black skinned and white skinned ectotypes respectively. Mean incubation periods were 25.8 days for the black skinned ectotype and 22 days for the white skinned ectotype. The values for mean percent hatchability were 26.8 % and 22.8 % for the black skinned and white skinned ectotypes respectively. Mean survivability values were 22.8 % for black skinned ectotype and 20 % for the white skinned ecotype. The mean egg quality parameters were 2.7 g and 2.4 g, weight for black skinned and white skinned ectotypes respectively. The mean egg lengths were 4.6 mm and 4.2 mm for black skinned and white skinned ectotypes respectively. Among the measured parameters, clutch size and egg length had very high significant difference (P

Comparative differentiation of morphometric traits and body weight prediction of giant African land snails with four whorls in Niger Delta region of Nigeria.

Abstract: Four hundred (400) adult black-skinned snails, two hundred (200) each of Archachatina marginata and Achatina fulica with weight ranging from 50.42 g to 198.84 g and from 100.10 g to 184.00 g for A. marginata and A. fulica respectively selected based on active appearance, number of whorls and no injury on the foot and/or shell of a base population from a population gathered in the wild within the Niger Delta region were used for the study. Data collected on the selected snails were used to evaluate phenotypic correlations and multiple regression functions which were used for predicting body weights from quantitative traits. Results obtained from the study showed that A. fulica snails with 4 whorls are genetically heavier than A. marginata snails with 4 whorls. This is because there was large and significantly different (P 0.05) phenotypic correlation coefficients (rp) between shell length and shell ‘mouth’ width (r = 0.250) and between shell ‘mouth’ length and shell ‘mouth’ width (r = 0.187) for A. fulica snails. The prediction equations evolved for body weights of growing snails with 4 whorls using quantitative traits from A. marginata and A. fulica indicated that these quantitative traits, namely; shell length, shell width, shell ‘mouth’ length and shell ‘mouth’ width best predicted body weight for A. marginata and A. fulica snails with 4 whorls. The quantitative or phenotypic traits of the two breeds of snail studied could be chosen to differentiate as well as characterize growing snails in the Niger Delta region of Nigeria.

Statistical analysis system of production line fault based on internet

Abstract: The current status of enterprise equipment management and maintenance management is briefly described.Through analysis of system functional requirements of the production site.the framework of a statistical analysis system of production line fault based on network and the function modules are presented in detail.The system database structure is designed by using MYSQL.The fault prediction model based on RBF Neural network is proposed.Based on B/S structure,Microsoft Visual Studio2008 c # as a programming language with MySQL database,the production line fault statistical analysis system based on network is developed.The system is applied in the statistics and analysis of a camshaft production line failure and proved the effectiveness.It also provides a practical tool for production line equipment maintenance and management for the enterprise.

Tropical agricultural science

Abstract: Malaysia is taking efforts to be self˗sufficient in rice production. However, the country is facing low availability of Cu and Zn in its soils. Even though these elements are required in small quantities for normal plant growth, their role in maximising yield is very impressive. The present study was conducted to assess the micronutrient Cu and Zn contents in selected paddy soils of Malaysia. Investigations carried out showed that marine alluvium [Guar, Sedaka, Keranji, Kuala Kedah, Kangkong, Sedu, Rotan and Kundur (Kedah)] and reverine alluvium; [Chempaka, Lubok Itek, Lating, Batu Hitam and Machang soil series (Kelantan)] were low in Cu and Zn contents. All soils were acidic in nature, with their pH values ranging from 4.3 to 6.5. Based on the results, extractable Cu and Zn concentration of soil varied within the range of 0.09˗1.70 and 0.51˗2.10 mg kg ˗1 in the soil series of Kuala Kedah and LubukItek, respectively. It was manifested that the micronutrient contents were below the critical level (Cu 0.1˗1.0 mg kg ˗1 and Zn 0.5˗3.0 mg kg ˗1 )according to the method of extracting analysis; Mehlich˗I. The sampling depth has shown a variation and the subsurface soil sampling exhibited lesser Cu and Zn contents as compared to the surface soil sampling. Findings of the research indicate that micronutrient deficiency occurs in the main rice regions of Malaysia, and this can be corrected by applying micronutrient fertiliser.
