a suitable diet and oviposition substrate are two basic needs for successful mass rearing of orius spp. and this may reduce their production costs. the effect of various foods containing eggs of ephestia kuehniella and sitotroga cerealella with various pollens were investigated on the biological parameters of o. albidipennis in the laboratory. moreover, survival, hatching rate and fecundity of ...

A total number of 66 day old Japanese quail chicks divided into 2 treatment groups (33 in each treatment) with 3 replications in each having 11 birds (male, 5 and female, 6) were reared on floor and in cage system for a period of 5 weeks to know the effect of rearing system on growth performance and carcass characteristics. At the age of 35 days, average body weight and feed intake were 102.15 ...

Four experiments were conducted to evaluate variations in the digestible lysine (DLYS) requirement estimates of broilers due to rearing environment, sex, or growth performance during the starter period (7 to 21 d) and due to sex, growth, and carcass yield characteristics during the grower period (21 to 38 d). In the first 3 experiments, chicks were allocated to either battery or floor pens. The...

self-concept component and its relationship with family structure and perceived parental rearing practices was examined in a sample of 163 adolescents ( 87 girls and 76 boys, aged 16 years old) selected randomly from high schools in tabriz. the subjects completed tennessee self-concept scale with 84 items and a 77-item inventory measuring parental rearing practices. results revealed no signific...

The main purpose of this study was to assess participation of rural women in goat rearing. Pakulla union under Sonatola upazila of Bogra district in Bangladesh was the locale of the study. All the rural goat rearing farm family women heads of Pakulla union constituted the population of the study. Data were collected from a sample of 100 women heads selected randomly during15 December 2008 to 14...

s of papers 41 (H=79.9 vs. I=81.0 eggs), and M (H=5.4 vs. I=20.9%). Also, strain effected (p<.001) bone BS (H=14.26 vs. I=12.26 kg) and volume (H=5.90 vs. I=6.27 cc). These results indicate that strain influences performance and bone parameters and suggest that increased Ca and P levels impact bones of laying hens only if provided during the rearing phase.

The aim was to investigate the growth of certain non-carcass components and hind limb tissues using allometric coefficients in Saanen goat kids reared under natural artificial systems slaughtered at 80 days or 120 age. 42 were used study [(24 (SA-80: 12 kids, SA-120: kids), 18 9 kids)] for determination indicated parameters. effect rearing system not significant weights tissue compositions, whi...

the influence of parasitoids on population dynamics is affected by host instar preference. the preference pattern of host instars is not fixed and is modified by the availability and relative abundance of host instars, intensity of defensive behaviors in a particular instar, and also maternal effects of the female forager. in this study, host instar preference of the thelytokous strain of lysip...

The bean pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae), is a serious pantropical pest of grain legumes. A suitable artificial diet is desirable for producing uniform insects for commercial purposes or research. Three previously described artificial diets, 1 newly-developed artificial diet, and cowpea (Vigna unguiculata (L.) Walp. (Fabales: Fabaceae)), the natural hostplant of M. ...

The introduction and survival of zoonotic bacterial pathogens in poultry farming have been linked to bacterial association with free-living protozoa. To date, however, no information is available on the persistence of protozoan communities in these environments across consecutive rearing cycles and how it is affected by farm- and habitat-specific characteristics and management strategies. We th...
