Food characteristics strongly regulate digestive enzymatic activity of insects through direct influences on their midgut mechanisms. Insect performance is better on diets that contain nutrients in proportions that fit its digestive enzymes. Little is known about the influences of rearing history on parasitism success of Habrobracon hebetor Say. This research focused on the effect of nutrient re...

A total of 1,257 gilts were used to determine the effect of space allowance during rearing and age at puberty on total pigs produced and removal rate over 3 parities. There were 2 treatments. In treatment 1, gilts were given a space allowance of 1.13 m(2)/gilt (15 gilts per pen), and in treatment 2, gilts were given 0.77 m(2)/gilt (22 gilts per pen). Gilts (38 kg and 75 d of age) were individua...

considering different fertility traits 411 cows from 73 farms used for economic analyses. from these, 202 lactating cows were selected for evaluating the fertility status. pre-tested data sheets were used to record the socioeconomic status of the farms including their assets, cost and return and productive and reproductive performance of the dairy cows. targets were set considering the situatio...

an experiment was conducted to study the effect on performance of silkworm bombyx mori l., when fed by leaves of different mulberry varieties a crd design with 12 tratments (including kamasari, kaeiryo ichinose, kaeerizhotezomigaeeshi, tachibana, ichinose, chekemaoha, yukishinogi, shin ichinose, wasemidori, roso, kenmochi, as well as some local varieties in 4 replications. the larvae were reare...

The dopaminergic (DAergic) system plays a pivotal role in incubation behavior via the regulation of prolactin (PRL) secretion in birds, however the role of the DA/PRL system in rearing behavior is poorly understood. The objective of this study was to investigate the relationship between the DA/PRL system and rearing behavior in a gallinaceous bird, the native Thai chicken. Incubating native Tha...

Mechoris ursulus (Roelofs) (Coleoptera: Attelabidae) is a pest weevil of Fagaceae oak trees in eastern Asia. The female has a distinct branch-cutting behavior in conjunction with oviposition in the acorns of its host plant. This study analyzed the factors influencing oviposition preference by carrying out continuous field surveys over the course of 2009-2010 and through laboratory rearing. The ...

Significance of stocking density in broiler production i.e. production performance, vitality and health condition of chickens, was established at the beginning of development of industrial poultry production. However, considering intensive development of selection work and creation of more productive genotypes which, at the same time, were more demanding in regard to rearing conditions, the cur...

1. The effects of perinatal malnutrition on behavioural development and adult shuttle-box avoidance performance were studied in Swiss white mice. 2. Mice were malnourished (a) from the 7th day of gestation until birth, (b) from birth until weaning, or (c) during both gestation and the sucking period. 3. Pups born of protein-restricted mothers had reduced birth weights, retarded development and ...

Acetylcholinesterase 1 (AmAChE1) of the honey bee, Apis mellifera, has been suggested to have non-neuronal functions. A systematic expression profiling of AmAChE1 over a year-long cycle on a monthly basis revealed that AmAChE1 was predominantly expressed in both head and abdomen during the winter months and was moderately expressed during the rainy summer months. Interestingly, AmAChE1 expressi...
