  • A study was conducted to investigate the effects of methods of feeding a total mixed ration (TMR) on behavior patterns of growing Hanwoo steers. A total of 15 growing steers (13 months old) were assigned to the control (fed roughage and concentrate mix separately), TMR1 (fed restricted TMR), and TMR2 (fed TMR ad libitum) groups. Individual behaviors of steers were observed for 48 hours. Compared with the control, feeding restricted TMR (TMR1) resulted in short eating time, long ruminating time, short chewing time, high frequencies of defecation, urination, and drinking of water, great numbers of boluses and chews, long ruminating time per bolus, low feed value index, high eating and chewing efficiencies (p<0.05). Compared with feeding restricted TMR (TMR1), feeding TMR ad libitum (TMR2) resulted in 1.2 kg more daily feed DM intake, long eating and chewing times, short resting time, great frequencies of defecation, urination and drinking of water, more numbers of boluses and chews, long ruminating time per bolus, low feed value index, low eating and high ruminating efficiencies (p<0.05) and similar chewing efficiency (p>0.05). Considering all these results, the wet TMR feeding system induced generally more desirable eating and ruminating behaviors of growing Hanwoo steers, but made the barn floor wetter due to more defecation and urination.

  • Background: Adolescent mothers may find the transition to motherhood to be overwhelming when compared to adult mothers. The adaptiveness of mother and infant feeding behaviors may greatly influence the quality of adolescent mothers' feeding interactions when compared to adult mothers. Purpose: To examine the adaptiveness of early maternal and infant feeding behavior between adolescent mothers and adult mothers. Method: In this secondary analysis, six adolescent mothers (< 20 years old) and six adult mothers were videotaped while feeding. The mothers were observed 3 times: when the infants were in the hospital, 1 month old, and 4 months old. The videotapes were coded using four scales of the Parent-Child Early Relational Assessment (PCERA). The two maternal scales were Positive Affective Involvement and Sensitivity/Responsiveness (PAISR) and Regulation of Affect and Behavior (RAB). The two infant scales were Infant Positive Affect, Communication, and Social Skills (IPACS) and Infant Regulation of Affect and Behavior (IRAB). The dyads were videotaped just before hospital discharge and at one and four months corrected age. The Wilcoxon signed-rank test was used to examine the difference in the PCERA between the two groups. Results: Adolescent mothers had a significantly lower score on the PAISR before hospital discharge (p-value 0.005) and at one month corrected age (p-value 0.008) than adult mothers. Adolescent mothers also had a significantly lower score on the RAB before hospital discharge, 1 and 4 months corrected age than adult mothers. There were no significant differences in IPACS and IRAB of infants of adolescent and adult mothers. Conclusion: Clinicians need to be aware of the differences in sensitivity that occur.

  • This study was done to investigate mother's attitude to breast feeding and the type of feeding according to the general characteristics of mother. The study sample consisted of 1696 mothers who had an infant and who were visiting five Hospitals or ten Public Health Centers in Seoul. Data was collected through a question aire from June, 1 to June, 30, 1993. The results are as follows : 1. The types of feeding were artificial feeding 2%), mixed feeding(21.7%) and breast feeding (26.1%). 2. The attitude of mothers to breast feeding was very positive for behavior tendency and cognitive attitude but the emotional attitude was low to moderate. 3. The attitude scores for the mothers were from 27 to 60 and 65% the mothers had scores that were high, 50-60 and mean was 49.86. 4. There was the significance between the general characteristics (type of delivery, obtaining in formation on breast feeding, type of feeding and baby's birth order) and the attitude score of mothers. 5. The attitude scores for the mothers by the general characteristics and type of feeding was not a 2-way interaction but the type of feeding had a main effects.

  • Feeding behavior of Temora turbinata was investigated through laboratory experiments with special emphasis on its food preference and consequent clearance rate on diatom and microbial components given as common natural food assemblage of coastal area (Uchiumi, Uwa Sea, Japan). Among available prey items, T. turbinata showed the highest clearance rate for Thalassiosira spp. ($0.23{\pm}0.08L\;Temora^{-1}day^{-1}$) followed by Chaetoceros spp. ($0.11{\pm}0.03L\;Temora^{-1}day^{-1}$), but clearance rates for other diatom, Nitzschia spp. was lower (0.03 to $0.07L\;Temora^{-1}day^{-1}$). Bacterial abundances showed no response against 24-h feeding of T. turbinata. Feeding of T. turbinata on heterotrophic nanoflagellates (HNF) was apparent when clearance rates of T. turbinata on diatoms were relatively low, but T. turbinata did not consume HNF as well as ciliates with Thalassiosira spp. of which clearance rate was highest. The results suggest that HNF and ciliates are possible supplementary prey item for T. turbinata, but their contribution as food sources can be limited by the presence of other prey items such as preferable diatom species.

  • Purpose: The purpose of this study was to explore characteristics of eating behavior according to level of functional status of elders with dementia (EWD), and to examine feeding time, change in food intake and body mass index (BMI) according to eating behavior. Methods: Participants were 149 EWD residing in long-term care facilities located in Seoul or Gyeonggi province and evaluated using the Mini-Mental State Exam-Korean version, Korean version-Activities of Daily Living, and Eating Behavior Scale (EBS). Feeding time, change in food intake, and BMI were also measured. Data were analyzed using SPSS 17.0, specifically descriptive statistics, ANOVA, and Chi-square test. Results: Participants' mean EBS score was $10.43{\pm}6.01$ and half of them (54.4%) needed moderate or total assistance while eating. The EBS score was significantly lower for elders with severe dementia compared to those with mild or moderate dementia; and elders with severe ADL dependence compared to those with mild or moderate ADL dependence. Lower EBS scores were related to longer feeding time, a greater the rate of participants with decreased food intake and 'underweight' BMI. Conclusion: Nursing intervention programs which are designed for EWD are needed to maintain functional eating skills and prevent negative consequences in this population.

  • The experiment was conducted to find out the effect of 4 feeding systems on growth, feed intake, eating behavior, lactation performance, gestation period, post-partum heat period, conception rate and parasitic infestation of Black Bengal goat. Twenty four does of approximately 1 year of age were randomly selected for 4 treatment (feeding systems) groups having 6 replications in each. Treatments were stall feeding ($T_1$), tethering ($T_2$), restricted grazing ($T_3$) and grazing ($T_4$). $T_1$ group was housed continuously and adequate amounts of natural grass were supplied for ad libitum feeding. $T_2$ group was tethered for grazing natural grass from 8 a.m. to 4 p.m. being moved at one hour intervals. Goats of $T_3$ group were allowed grazing from 8 a.m. to 1 p.m. $T_4$ group was grazed from 8 a. m. to 4 p.m. Concentrate supplement was given at the rate of 150 g per day per goat for all of the treatment groups. Duration of experiment was 219 days. Daily live weight gain was significantly (p<0.05) higher in case of stall fed goats than that of others. DM intake also significantly (p<0.05) differed among the treatment groups and was 3.40 3.95, 3.76 and 4.05 per cent of their live weight for stall feeding, tethering, restricted grazing and grazing groups, respectively. Rate of rumination was significantly (p<0.05) higher in case of tethering group of goats than that of others. Birth weight of kids, milk yield, lactation period and post-partum heat period were significantly higher in case of stall fed goats than others. Tethering group showed significantly (p<0.05) higher litter size than others. Infestation rate of Fasciola was significantly (p<0.05) higher in the grazing group. In conclusion, it may be stated that among these feeding groups overall performance of stall fed goats was more satisfactory, and that the tethering group showed better performance than the others.

  • The pear psylla, Cacopsylla pyricola, is a very small sap-feeding insect of many commercial pear varieties that could be considered the most serious insect pest of pear. Detailed information on plant penetration activities of the pear psylla is essential to study its feeding behavior used to evaluate resistant traits to chemical control. The application of the electrical penetration graph technique (EPG) could provide a relevant insight into the nature of this resistance. EPG waveforms of C. pyricola were characterized on the basis of amplitude, frequency, voltage level, and electrical origin. Feeding behaviors of C. pyricola were recorded and analyzed by EPG analysis. During EPG monitoring, waveform PA occurred at the start of stylet penetration of pear leaf epidermal cell. Waveform PB followed, in which stylet secreted saliva was observed. Waveforms PC1 and PC2 involved penetrating and sucking behaviors in parenchyma cells and vascular parenchyma, respectively. In addition, waveform PC1 represented salivation into bundle sheath cells and ingestion from parenchyma. Otherwise, behaviors of salivation into phloem and ingestion from phloem produced waveforms PE1 and PE2, respectively. On the other hand, ingestion from xylem tissues showed waveform PG. Among the feeding patterns of C. pyricola described above, phloem feeding patterns occurred most frequently, followed by xylem feeding and parenchyma penetration patterns in descending order.

  • Purpose: The purpose of this study was to investigate the condition, recognition of breast feeding of 273 nurses. Method: Data was collected using a structured questionnaire form April to June 2007. The subjects were 273 nurses in Kyunggido. The data analysis was done with descriptive statistics, $x^2$-test procedures using SPSS/WIN 12.0 PC. Result: There are 23.9% of child day care center, 5.2% of rest room for women, 16.8% of breast feeding room in workplace. Rate of breast-feeding practice was 78.4% of nurses. The reasons why they could not perform the breast-feeding include mother's job(45.4%), lacking breast milk(25.8%). The characteristics of nurses found to be related breast-feeding include age, number of employers. Conclusion: The results showed that the rest supports of the work environment was insufficient to perform breast-feeding in the workplace. These results suggest that nursing intervention for employed mother's breast-feeding practice behavior promotion should focus on characteristics influencing factors on workplace. Also, efficient breast-feeding education program for employed mothers should be developed by continuous qualitative researches based on breast-feeding experiences of employed mothers.

  • BACKGROUND/OBJECTIVES: Filipino children aged 6-10 yrs are consuming poor quantities and quality of food based on the 2013 Philippine National Nutrition Survey. During these years healthy eating habits must be formed through family influence. Within this background, a complete package of nutrition intervention-feeding and nutrition classes, was pilot tested in selected schools to determine 1) changes in nutrition attitude and behavior and 2) food intake of schoolchildren after the intervention. SUBJECTS/METHODS: A quasi-experimental design was used in the study. School children aged 7-9 yrs enrolled in selected Philippine public elementary schools and their mothers/caregivers were the study participants. Profile and socio-demographic data were collected from each participant at baseline. The nutrition behavior and food intake of children were determined using the modified Child and Diet Evaluation Tool (CADET) and the 24-h food recall form, respectively. Data were analyzed using Stata version 15. RESULTS: No significant differences in characteristics were found among the 339 child-mother pairs in the 4 study groups. The modified CADET recorded improved mean attitude scores of children ranging from 22 to 24 points at endline in the group receiving both lunch feeding and nutrition education classes (group 3). The perceived better behavior of children was reported by their mothers in terms of increased intake of milk and vegetables and decreased consumption of sugar. These improvements were supported by the actual food intake of children obtained from the 24-h food recall. CONCLUSIONS: Family involvement, particularly of mothers/caregivers, appeared to be an important factor in shaping the children's eating behavior. An intervention package with lunch feeding and nutrition classes resulted in a substantial improvement in children's behavior and actual food intake with increased levels of vegetables and milk while lowering sugar consumption. The adoption of the intervention package in public elementary schools should therefore be pursued.
