Over the past 20 years, neonatal mortality rates for preterm infants, particularly those born extremely preterm and with a very low birth weight, have decreased steadily. As more very immature preterm infants survive, provision of enteral feeding has become a major focus of concern. According to many experts on neonatal nutrition, the goal for the nutrition of preterm infants should be to achieve a postnatal growth rate approximating that of a normal fetus of the same gestational age. Total parenteral nutrition for maintaining nutritional integrity is mandatory before successful transition to enteral feeding. Early initiation of trophic enteral feeding is vital for postnatal adaptation. Recently published randomized controlled trials provide no evidence to support the practice of postponing enteral feeding to reduce the incidence of necrotizing enterocolitis. Early trophic feeding yields demonstrable benefits and there is currently no evidence of any adverse effects following early feeding. Preterm milk from the infant's own mother is the milk of choice, which can always be supplemented with a human milk fortifier. Here we review over 50 randomized controlled trials and over seven systematic reviews published on neonatal parenteral and enteral feeding of preterm infants. Neonatologists must make use of the evidence from these studies as a reference for feeding protocols for preterm infants in their NICUs are to be based.

The purpose of this study was to compare the breast feeding practice rates and mothers' breast feeding empowerment in preterm (gestation age [GA]<34), late preterm ($34{\leq}$GA<37), early term infants ($37{\leq}$GA<39). We surveyed 33 preterm, 22 late preterm, and 30 early term infants at a 'Baby-Friendly Hospital' in D city. The data were collected from October 1st, 2008 to February 28th, 2010 through the medical records of the infants and their mothers. We also checked the mothers' breast feeding empowerment at discharge day. The rate of breast feeding in the late preterm and preterm infants was significantly lower than that of the early term infants. The score of mothers' breast feeding empowerment in the late preterm and preterm infants was also significantly lower than that of the early term infants. The breast feeding education program is required for the mothers who have preterm and late preterm infants considering the low rate of breast feeding.
Objectives: This study examined whether the infant feeding type and duration are related to the introduction of complementary feeding, and whether the appropriate introduction of complementary feeding in infancy is related to tooth decay in toddlers. Methods: The subjects were 1,521 toddlers among 2~3 year old children in the Korea National Health and Nutrition Examination Survey from 2008 to 2015. The toddlers were divided into the appropriate group (4~6 months) and delayed group (>6 months) according to the timing of complementary feeding introduction. Results: The delayed group were 26.5% of subjects and the formula feeding period in the appropriate group and delayed group was 8.4 and 10.3 months, respectively (P=0.002). On the other hand, there was no difference in the breastfeeding period between the appropriate group and delayed group (P=0.6955). Early childhood caries was more common in the delayed group (P=0.0065). The delayed introduction of complementary feeding was associated with a risk of early childhood caries according to the logistic models (OR 1.81, 95% CI 1.27-2.57). Conclusions: The introduction of complementary feeding is associated with early childhood caries. Therefore, the importance of the proper introduction of complementary feeding in infancy should be emphasized, and public relations and education for maternal care and breastfeeding should be provided through health care institutions.
Purpose: This study was conducted to assess the breast feeding rate and maternal adaptation of mothers with infants and children in early childhood in a community. Methods: This descriptive study was conducted from November to December 2015, and included a total of 283 mothers of infants and children in early childhood. The data were analyzed using descriptive analysis, the ${\chi}^2-test$, and one way ANOVA. Results: The rates of breast feeding after birth were 76.3% (1 month postpartum), 69.3% (3 months postpartum), 53.4% (6 months postpartum), 32.2% (9 months postpartum), and 22.6% (12 months postpartum). The level of maternal adaptation of subjects was $3.78{\pm}0.54$. Subjects who were breastfed until 9 months postpartum had a higher level of maternal adaptation than those who stopped breast feeding at 1 month postpartum (F=3.926, p<.002). The breast feeding rate of subjects who were educated about breast feeding after childbirth was significantly higher than that of those who did not receive breast feeding education after delivery. Conclusion: To increase the breast feeding rate and maternal adaptation, community health nurses should develop and provide breast feeding programs to mothers soon after childbirth.
A total of 120 growing crossbred pigs ($Landrace{\times}Large$$White{\times}Duroc$) with equal numbers of barrows and gilts were used in the feeding trial in a $2{\times}3$ factorial arrangement (gender by feeding regimens) to investigate the effect of phase feeding on growth performance during the 25 to 58 kg body weight growth stage, and 6 pigs (three of each sex) were used in a metabolic trial. The growing period was divided into two phases and 4 different CP diets were used to make 3 different feeding regimens (GE18-GL18; 18% CP diets for both early and later growing period, GE18-GL16; 18% CP diet for early and 16% CP diet for later growing period, GE19-GL17; 19% CP diet for early and 17% CP diet for later growing period). There were no significant differences in growth performance among treatments during the entire growing period. However, during the later growing period, feed intake of barrows was significantly higher than that of gilts (p<0.05). Average daily gain of barrows was higher than that of gilts (p>0.05). Based on the result, growth performance differences between barrows and gilts appeared to begin after 40 kg of body weight. There was no significant difference in digestibility among treatments or between sexes. During the early growing period the 18% CP diet showed better digestibility than the 19% CP diet. However, during the later growing period, the 18% and 17% CP diets exhibited similar digestibilities, although 16% CP diet showed slightly lower digestibility than 18% and 17% CP diets. During the early growing period, fecal N and P excretion of pigs fed the 19% CP were higher than that of those fed the 18% CP diet. During later growing period, fecal N and P excretion by those receiving the two phase feeding compared to single phase feeding was reduced by 10.2% and 2.0%, respectively. In the gilts, the cost reduction by two phase feeding (GE18-GL16) compared to single feeding was around 3.81%, but that of barrows was only 0.52%. The results suggested that the same nutrient levels could be applied to barrows and gilts during the growing period. Also, this study suggested the optimum protein and lysine level for early and later growing pigs to be 18% CP, 1.0% lysine and 16% CP, 0.8% lysine, respectively. Feeding two diets to growing pigs, i.e., two-phase feeding, would be more appropriate than feeding a single diet on economic and environmental considerations.
A total of 120 finishing crossbred pigs ($Landrace{\times}Large$$White{\times}Duroc$) with equal numbers of barrows and gilts weighing 58.5 kg body weight were used in a feeding trial, and 6 pigs (three of each sex) were used in a metabolic trial to investigate the effect of phase feeding. Finishing period was divided into two phases and 4 different diets were fed for those periods. Growth performance was not significantly different among treatments within the same sex. This result showed that 16% crude protein for early finishing period and 14% crude protein diet for late finishing period should be optimum. During the early finishing period, only feed intake was significantly different between sexes (p<0.01), but in late finishing period daily weight gain (p<0.001) and feed intake (p<0.01) of barrows were significantly higher than those of gilts. During the early finishing period, digestibilities of dry matter, protein and phosphorus were significantly higher in gilts than in barrows (p<0.05). However, there was no treatment effect within same sex during the early and late finishing period. During early finishing period, excretion of N of pigs fed 16% CP diet in early and 14% CP diet in late-finishing period was less than that of pigs fed 17% CP diet in early and 15% CP diet in late-finishing period (p<0.05), but the difference was not significant. During the late finishing period, N excretion with two phase feeding was reduced by 8.5% compared with single feeding. In gilts, total cost reduction by two phase feeding compared to single feeding was 9.1%, but in barrows it was just 3.19%. Relative margin increased with two phase feeding by 2.5% in gUts and 0.2% in barrows. There was a tendency that backfat thickness at 10th rib of gilts was thinner than that of barrows (p>0.05). Within the same sexes, there was no treatment effect on back fat thickness (p>0.05). Carcass grade was improved by two phase feeding compared to single feeding. Carcass grade of gilts was significantly better than that of barrows (p<0.001). From this results, it is concluded that finishing pigs could be fed two-phase diets to improve profit and reduce pollution.

This study examined the impact of using total mixed ration (TMR) and concentrate on feed intake, daily gain, carcass yield grade, and carcass quality grade of Hanwoo steers and its subsequent economic efficiency. Thirty six 7-month-old Hanwoo steers were assigned to one of the four treatment groups, and each group was divided into three repeated pens, with each repeated pen comprising three steers. The treatment groups were: 1) separate feeding with commercial concentrate and forage (namely, SCF) for the entire experimental period; 2) TMR feeding for a growing period followed by SCF for the early and late fattening period (namely, TMRGSCF); 3) TMR feeding for growing and an early fattening period followed by SCF for the late fattening period (namely, TMREFSCF); and 4) TMR feeding for the entire experimental period (namely, TMRW). The results showed that the SCF treatment had significantly (p < 0.05) higher feed intake during the growing period than other treatments. In contrast, the total feed intake had little difference during early and late fattening as well as the whole period regardless of feeding strategies. Daily gain showed no difference during the growing period. However, it was significantly higher in SCF and TMREFSCF treatments for the early and late fattening period, respectively (p < 0.05). The daily gain during the total raising period is in the order of TMREFSCF > TMRGSCF > SCF > TMRW. Carcass characteristics, including carcass weight, loin eye muscle area, and carcass yield grade, did not significantly differ among different treatments. However, TMRW treatment, wherein TMR was fed for a long time, showed that the cold carcass weight was less compared with other treatments, but carcass yield grade was higher with thinner backfat. Backfat thickness was in the order of SCF > TMRGSCF > TMREFSCF > TMRW, showing that the thickness reduced with longer TMR feeding (p < 0.05). TMRGSCF, which numerically had a higher carcass quality grade, showed higher economic efficiency, whereas SCF showed low economic efficiency. In conclusion, it was more feasible to apply TMR strategy in the growing and early fattening period and then SCF for the early or late fattening period to improve carcass yield, quality grade, and economic efficiency.

Purpose: The purpose of this study was to identify the effects of an oral stimulation program on premature infant's transition from tube feeding to bottle feeding, decrease in desaturation during feeding, and early discharge. Methods: This quasi-experimental study was performed in one neonatal intensive care unit (NICU) of an university hospital. The control group data (n=69) were obtained from June 2008 to May 2009, and the experimental group data (n=67), from June 2009 to May 2010. The oral stimulation program (OSP) was provided daily before feeding for the experimental group until transition to bottle feeding was completed. Results: The OSP group began bottle feeding earlier and were on complete bottle feeding earlier than control group. Discharge delay due to feeding desaturation was lower than for the control group. Conclusion: The results indicate that OSP for premature infants was helpful in transition from tube feeding to bottle feeding and early discharge and thus can contribute health and development in premature infants.
Objectives: The aim of this study was to investigate the effect of breastfeeding on the occurrence of early childhood caries in Korean infants and toddlers. Methods: Data on oral examinations of infants and toddlers of the National Health Insurance Service were analyzed. The study subjects were children who participated in both the first, second, and third oral examinations and the first general health examination in 2008-2017 (n=142,185). Based on the responses to the questionnaire, the subjects were classified into breastfeeding, formula feeding, and mixed feeding groups. The participants were monitored for the development of early childhood caries in three sequential oral examinations. Results: Based on the oral examination results conducted at 54-65 months old, the decayed-filled teeth index of the breastfeeding group was the highest (2.03±3.08), followed by the mixed (1.96±3.03) and the formula feeding groups (1.82±2.91). The Cox proportional hazard regression model including all the variables showed that the risk of developing dental caries was significantly lower in the formula (hazard ratio [HR], 0.85) and mixed feeding groups (HR, 0.91) than in the breastfeeding group. Conclusions: Breastfeeding children have a higher risk of early childhood caries; therefore, oral hygiene education and regular dental check-ups are necessary.

The purpose of this study was to investigate the prevalence of severe early childhood caries and feeding pratices in preschool children. The subjects of study were six hundred and seventy-two preschool children in Iksan city. Severe early childhood caries(S-ECC) was defined as the presence of one or more cavitated, missing due to caries, or filled smooth surfaces in primary maxillary anterior teeth. The caregivers of children were given a questionnaire including age, gender, birthweight, and feeding practices. The prevalence of S-ECC was 34.5%. The prevalence was significantly higher when there were the habit of sleeping while feeding, the habit of feeding sour or sweet content in the bottle, and the habit of using the pacifier. Birth weight, breast-feeding, bottle-feeding, and the sippy cup habit showed no significant association with the prevalence of S-ECC. There were significant positive associations between breast-feeding and sleeping while feeding, between bottle-feeding and the pacifier, between sleeping while feeding and sour or sweet content in the bottle, between sleeping while feeding and the sippy cup, between sleeping while feeding and the pacifier, and between the sippy cup and the pacifier. There were significant negative associations between breast-feeding and the pacifier.
