The purpose of this research was to study the effects of antenatal breast care on decreases in breast discomfort and increases in the breast feeding rate during the postpartum period. A nonequivalent control group posttest research design was used. The experimental group consisted of fifty -one pregnant women(primigravida) who were receiving antenatal care in the OBGYN clinics of four hospitals between March 5 and May 30, 1991. The control group was made up of seventy - five postpartum women who delivered at two hospitals OBGYN clinic and one midwife clinic between May 4 and June 15, and between September 5 and October 15, 1991. Data were collected via telephone interviews on the seventh postpartum day and at the end of the second month. Data analysis methods used frequencies and the x$^2$- test. The results were as follows : 1. The rate of breast feeding practice at two months was higher in the experimental group(70.6%) than in the control group(25.3%) (p<.01). 2. Nipple soreness in the early breast feeding period was lower in the experimental group(14.6%) than in the control group(25.3)(p<.01). 3. Severe breast discomfort in the early breast feeding period was lower in the experimental group (12.5%) than in the control group(39.2%)(P<.01). 4. There was a significant relationship between the breast feeding practice and the planned feeding method(p<.05), and between breast feeding practice and nipple soreness(p<.01) in the experimental group, and the presence of a job(p<.01), the sex of the infant(p<.05), and the first feeding time(p<.05) in the control group. 5. The reasons for unsuccessful breast feeding were a deficiency of breast milk (66.7% in the experimental group, 30.4% in the control group), poor sucking on the part of the baby(13.3% in the experimental group, 21.4% in the control group).
Background: Liquid feeding system has been introduced to domestic swine farms, but negative cognition about liquid feeding system has been remained for feed waste decay related with poor management and microbial contamination. For these reasons, this study was conducted to evaluate the effects of feeding method in lactating sows. Methods: A total of 30 mixed-parity (average 4.13) lactating sows (Yorkshire ${\times}$ Landrace) with an initial BW of $218.8{\pm}19.5kg$ was used in a 3 week trial. Sows were allotted to 1 of 2 treatments in a completely randomized design by their body weight, backfat thickness, parity and alive litter weight. One of treatments was dry feeding and the other was liquid feeding (water to feed ratio, 1:1). Experimental diets contained 3265 kcal ME/kg, 12.6 % CP, 5.76 % EE, 1.09 % total lysine, 0.25 % total methionine, as fed basis. Results: Dry feeding treatment had high body weight loss rather than liquid feeding treatment (P = 0.04). Dry feeding treatment had tendency to increase litter weight at 21d of lactation (P = 0.06) and litter weight gain (P = 0.04) during lactation period (0-3 week). Sows fed dry feeding method made milk containing high content of casein and total solid rather than sows fed liquid feeding method (P = 0.04). In addition, dry feeding treatment had tendency to higher content of milk fat, protein and solid not fat on 21d of lactation (P = 0.07). Sows fed dry feeding type also showed higher milk energy content in milk of 21d lactation (P = 0.05). Furthermore, liquid feeding treatment showed high occurrence in feed waste during lactation period (P <0.01). Conclusion: Dry feeding method was more suitable feeding method to lactating sows under high temperature environment like lactating barn.
This study was designed to test the effects of changes in energy and protein intake levels on the maternal milk amino acid concentrations over the short-term in lactating mares. Three lactating mares were enrolled for the study 7 weeks after parturition. A low-energy and low-protein diet (LEP) was administered during the first week of the study, followed by administration of a high-energy and high-protein diet (HEP), again for a week (day 1 to day 7), and milk was sampled thrice daily at intervals of 8 h during the study period. The mean amino acid concentrations in the maternal milk, except for those of proline, serine and valine, were significantly higher in the HEP feeding period than during the LEP feeding period (p<0.05). The sum of the concentrations of all the amino acids (TAA) in the maternal milk samples during the HEP and LEP feeding periods was 1,644.9${\pm}$26.9 and 1,542.3${\pm}$36.0 mg/100 g, respectively, the difference between the two was not significant. When the ratio of each amino acid concentration to the TAA in the maternal milk was analyzed, there were significant differences between the HEP and LEP feeding periods for all amino acids, except glycine, serine, alanine and histidine. It was found that the concentrations of glutamic acid+glutamine, serine, threonine, arginine and valine were significantly higher (p<0.05) on day 1 than on day 7 during the LEP feeding period, and there were no such differences during the HEP feeding period. In regard to the effects of changes in the energy and protein intake levels in lactating mares, no changes in milk amino acid concentrations were found following administration of HEP for a week, whereas 7 days of administration of LEP was associated with a decrease in the amino acid concentrations.

The purpose of this study was to examine dietary habits and nutrient intakes according to feeding method during infant period in elementary school students. Subjects were 1,251 elementary school students. Subjects were divided into three groups, breast-fed group (N=508), formula-fed group (N=397), and mixed group (N=346), according to feeding method during infant period. The questionnaire was composed of general characteristics, dietary conditions during infant period, dietary behaviors, and dietary intakes and was completed by children and children's parents. Average age, height, weight, and body mass index were 11.6 years, 139.0 cm, 34.6 kg, and $17.8kg/m^2$, respectively. The formula-fed group showed a smaller proportion of subjects with colostrum feeding (P<0.001) compared to the breast-fed and mixed groups. Frequency of eating snacks was significantly higher in the mixed group than in other groups (P<0.05). There was no significant difference in dietary habit total score and nutrient intakes according to feeding method during infant period. Feeding method in during infant period was associated with dietary habits (milk and vegetable intake habits) up to growth period of elementary school. A longitudinal and systematic study is needed to clarify this relationship.
The most important times during the development of young chicks are the days immediately prior to hatching and the days immediately after hatching, known as the perinatal period. A sufficient supply of nutrients during the perinatal period is a crucial during the late stage of embryonic development and the starvation period of the young chicks. The delayed post-hatch holding time can restrict the development of the gastrointestinal tract, reduce final body weight, impair muscle development, and change immunological capacities. These symptoms are deleterious to the development of young chicks. Therefore, the post-hatch holding time and its influence on the fitness of young chicks are major concerns to the poultry industry. The in ovo feeding is a practical technology for perinatal nutrition to optimize poultry production and for attenuating the stress experienced by fasting young chicks. This study will discuss in ovo feeding and its effect on the development of the chick embryo, the establishment of a healthy microbiota, and the improving immune response.
The purpose of this descriptive study was to investigate the determinants of mother's choice of infant feeding method on immediate postpartum period & the breast feeding practice after 1, 2, 3, 4, 5months. The subjects were 170 mothers who were delivered at 2 hospital, 2 OBGY clinics, 1 midwifery in Jinju, the data were collected from Jan. 1 to Feb. 20 of 1991, form each subject at two periods of time ; postpartum 2 or 3 days via interview, 5months via telephone interview. The results were as fellows : 1. The propotion of mother planned exclusive breast-feeding was 66.5%, milk feeding 17.6%, mixed feeding 15.9%, End 38.9% of mothers planned to breast-feed their infants for 4-6moths, 25.7% for more than 12 months. The major reasons for selection of milk feeding method were the presence of mother's job(26.7%), the conditions of breast & milk production(23.7%). 2. There were significant relations between the choice of feeding method & the presence of s job(p<.01), & parity(p<.01). 3. The percentages of subjects that were received education about the advantages & method of breast feeding were 63.5%, 38.2%, respectively, & the informants were mass media, 89.8%, 81.5%. 4. The most of mothers had the knowledge about the advantages of breast feeding. 5. The percentage of mothers that practiced breast feeding on postpartum were 75.9%. 6. The rates of breast feeding practice by duration were more than 5months, 60.5%, 1 month, 27.1%, 2-4 months. 12.3%. 7. The reasons for the stop of breast feeding were the decrease of milk volume(22.9%), the presence of mother's job(17.4%). 8. The duration of breast feeding practice were differed significantly by the presence of mother's job, type of delivery, rooming-in, planned duration of breast feeding, the first feeding time.
Sixteen Holstein heifer calves were used in an 112-day trial to study the effects of probiotic supplementation on growth performance and rumen metabolism. Calves were divided into four groups of four calves each, with two groups receiving the probiotic supplement and two groups serving as controls. Calves were limited to 1.6 kg dry matter of a corn-barley based grain mix per day. Long-stem bromegrass hay was fed as forage the first 56 days and bromegrass silage the last 56 days of the trial. Probiotic (28 g/d/calf) was fed along with the grain mix twice daily. Data were analyzed for the entire trial and also for the separate hay and silage feeding periods. Total weight gain and average daily gain were not affected (p>.05) by probiotic supplementation. Dry matter intake was lower (p<.05) and feed efficiency (kg feed/kg weight gain) was improved slightly during the hay feeding period for the probiotic-supplemented calves. Wither height gain was greater (p<.05) during the hay period and lower (p<.05) during the silage period for probiotic-supplemented calves. Heart girth gain was improved (p<.07) by probiotic supplementation, particularly during the hay feeding period (p<.05). Total rumen volatile fatty acid (VFA) concentration was higher (p<.05) with the probiotic-supplemented calves. Molar proportions of individual VFA were not affected (p>.05). Rumen ammonia-N and plasma urea-N concentration were lower (p<.05) for probiotic-supplemented calves during the hay feeding period. Total tract nutrient digestibility was not affected (p>.05). Some improvements in animal performance and changes in rumen and blood metabolites were observed when calves were supplemented with probiotic. Effects due to probiotic supplementation were most pronounced during the hay feeding period.
Thirty one Hanwoo steers were used in a completely randomized design experiment to see the effects of concentrate feeding method (group vs. individual feeding) and age at slaughter (26 vs. 28 months of age) on growth performance, feed intake and carcass characteristics. Steers were randomly assigned to one of four groups, G26 (group feeding slaughtered at 26 months of age), G28 (group feeding slaughtered at 28 months of age), I26 (individual feeding slaughtered at 26 months of age) or I28 (individual feeding slaughtered at 28 months of age). Amount of concentrate were restricted to 1.5% of BW for the growing period and 1.8% of BW for the early fattening period in both groups. For the late fattening period, concentrate were given ad libitum for G26 and G28, but were given up to 1.7% of BW for I26 and I28. Average daily gains were higher in individual feeding groups (I26 and I28) than those in group feeding groups (G26 and G28) for the early fattening period (p<0.05). ADGs were higher in group feeding groups than those in individual feeding groups (p<0.05). Concentrate intake in individual feeding groups tended to be higher compared to that in group feeding groups for the early fattening period, but tended to be higher in group feeding groups compared to that in individual feeding groups for the late fattening period. Feeding method or slaughter age had no significant effects on carcass characteristics, yield grade and quality grade. Shear force and tenderness of longissmus muscle were higher in groups slaughtered at 28 months of age than in groups slaughtered at 26 months of age (p<0.05). Feeding method or slaughter age had no effects on cooking loss, water holding capacity, juiciness, flavor, moisture, protein and fat of longissmus muscle.

Pierre Robin syndrome is characterized by micrognathia, glossoptosis, and cleft palate. Infants with Pierre Robin syndrome causes feeding difficulty, upper airway obstruction, and other symptoms. This study aims to examine the effects of applying dysphagia treatment to infants with Pierre Robin syndrome. The study participant was an infant who was born four weeks premature and referred for dysphagia treatment approximately 100 days after birth. At the initial assessment, the infant showed oral sensory sensitivity, a high level of facial and masticatory muscle tension, and a low stability of the chin and cheeks with almost no normal "sucking-swallowing-breathing" pattern. We set the baseline period and intervention period using the AB design. During the baseline period, non-nutritive sucking training using a rubber nipple was conducted without implementing an oral stimulation intervention. During the intervention period, non-nutritive sucking training and an oral stimulation intervention were performed. After the intervention period, the infant's daily oral intake and oral intake per time significantly increased compared to that during the baseline period. We observed that the oral intake time of the infant decreased during the intervention period compared to that in the baseline period, which indicated an improvement in control over the chin, tongue, and lip movements, a change in muscular tension, and stabilization of the "sucking-swallowing-breathing" pattern. We provided dysphagia treatment before breastfeeding, it was positive effects such as normal development of the infant, transition from tube feeding to bottle feeding, and enhancement of overall oral motor function.
The objective of this study was to examine whether feeding induced hypovolemia (decrease in plasma volume) acts on the regulation of feed intake in goats fed on dry forage. In order to prevent feeding induced hypovolemia, a 2 h intravenous infusion (16-18 ml/min) of isotonic mannitol solution was begun 1 h prior to feeding and continued until 1 h after the start of the 2 h feeding period. The intravenous infusion of isotonic mannitol solution (MI) decreased plasma osmolality by 1.0%, plasma total protein concentration by 4.2% and hematocrit by 5.9%, respectively. In comparison with no infusion (NI), MI significantly decreased thirst level by approximately 13%. At the completion of the 2 h feeding period, cumulative feed intake had been increased by 43% by MI. In conclusion, feeding induced hypovolemia in goats fed on dry forage increased thirst level more than the increase in plasma osmolality did. The results demonstrate that feeding induced hypovolemia is one of the factors controlling feed intake in goats fed on dry forage.
