PURPOSE This study was conducted to compare the paternal rearing behavior and rearing stress level between fathers with a preschooler and fathers with school children so that it can be utilized as a basic source for developing parental rearing education programs. METHODS A descriptive comparative method was conducted to identify the paternal rearing behavior and paternal rearing stress. Respo...

OBJECTIVE To assess the influence of infant rearing on the behavior of depressed adult female Macaca fascicularis and the influence of depressed infant-rearing adult female Macaca fascicularis on their infants in a free enclosure environment. METHODS Here, 20 depressed subjects and then 20 healthy subjects were randomly selected from a total population of 1007 adult female Macaca fascicularis...

BACKGROUND As farmers do not often keep a record of the expenditures for rearing, an economic tool that provides insight into the cost of rearing is useful. In the Netherlands, an economic tool (Jonkos) has been developed that can be used by farmers to obtain insight into the cost of rearing on their farm. The first objective of this study is to calculate the total cost of rearing young stock i...

the number of lambs sold per ewe mated in the breeding flock has a considerable impact on sheep operation profitability. this depends primarily on fertility, prolificacy (# of lambs), and lamb survival, mothering ability, milk production of the ewe and lamb growth rate. optimal reproduction does vary by environment and management system – some sheep operations don’t want a lambing rate over 200...

This paper exploits a unique ongoing experiment to analyze the effects of early rearing conditions on physical and mental health in a sample of rhesus monkeys (Macaca mulatta). We analyze the health records of 231 monkeys that were randomly allocated at birth across three rearing conditions: mother rearing, peer rearing, and surrogate peer rearing. We show that the lack of a secure attachment r...

The effect of outdoor rearing duration (75 v 50 days) and rearing system (outdoor v indoor based systems) of Iberian pigs on the chemical composition (fatty acid composition of fat and intramuscular fat, moisture, salt, pigment concentrations and water activity of lean meat), the instrumental colour (CIEL*a*b* system) and the sensory characteristics (descriptive analysis) of dry-cured hams were...

abstract different responses of silkworm larvae under various rearing climate condition would help to obtain better economic performance of some silkworm varities in specific climate conditions. the effect of 4 rearing climate conditions including 1) standard 2) high temperature and humidity, 3) high temperature and low humidity and 4) temperature fluctuation were investigated on the performanc...

A rearing system based on a diet gelled with Water-Lock G-400, a synthetic superabsorbent (poly(2-propenamide-co-2-propenoic acid, sodium salt)) (WL), was compared with the standard rearing system (liquid diet suspended in acetate fibers) for the mass production of screwworms, Cochliomyia hominivorax (Coquerel). The WL rearing system yielded 2% heavier pupae, 32% higher egg to pupa survival, an...

protein oxidationm.longissimus dorsi andm. semimembranosuswas studied in ram lambs of northeastern bulgarian fine wool breed and cross of this breed with ile de france, reared and in doors and on pasture.the degree of protein oxidation is determined by measuring the content of carbonyls, formed during the storage of the investigated muscles at low temperatures(4˚с till6thday and -20˚с till90thd...

Female mosquitoes use abiotic and biotic factors, such as the presence of heavy metals or parasites, to determine the acceptability of oviposition sites. Some biotic factors can originate from mosquito larvae. When mosquito larvae are starved or infected with trematode metacercaria, they render associated water unacceptable to ovipositioning females. Internal symbiotes are common in wild mosqui...
