Objective: This study was conducted to evaluate the effect of offering (OSF) or not (NSF) supplemental feed at milking on temperament (TS), udder hygiene (UHS) and body condition (BCS) scores, and milk yield per milking (MYM), milk quality traits, and profitability of primiparous Anatolian buffalo cows at 90 days of lactation confined in closed-tied (CB) or semi-open free-stall (OB) barns. Methods: In Experiment I, 108 cows were selected to encompass four treatments (OBOSF, OB-NSF, CB-OSF, and CB-NSF) of 27 cows, considering barn type (OB and CB) and supplementary feed (OSF and NSF) at milking. In Experiment II, 60 OB cows were selected to encompass one of five groups of 12 cows each: i) no supplemental feed (CON), ii) commercial concentrate (CC), iii) CC + corn silage (CCS), iv) CCS + alfalfa hay (CSA), or v) CC + ryegrass silage (CRS) at milking. Results: The TS and UHS of the OB and OSF cows were lower (better) than those of the CB and NSF cows, respectively. The OSF increased milk protein, lactose, and solids-not-fat but decreased milk freezing point and electrical conductivity compared with the NSF. The MYM and milk fat of the OB-OSF cows were higher than those of the OB-NSF and CBNSF cows. The TS and UHS of the cows negatively correlated with MYM and some milk chemicals (fat, protein, and solids-not-fat), but BCS correlated positively. The TS and milk electrical conductivity of the CCS, CSA, and CRS cows were lower than those of the CON and CC cows, but BCS, MYM, and milk fat were higher. Partial budget analysis identified a higher net profit for supplemental feed-offered groups (OB-OSF, CCS, CSA, and CRS). Conclusion: Offering roughage with concentrates at milking for indoor primiparous buffalo cows is more conducive to well-being, milk yield, milk quality, and economy.

This study aimed to determine the effects of parenteral selenium (Se) and vitamin E supplementation on economic impact, milk yield, and some reproductive parameters in high-yield dairy cows in the dry period and in those at the beginning of lactation. At the beginning of the dry period, cows (n = 323) were randomly divided into three groups as follows: Treatment 1 (T1), Treatment 2 (T2), and Control (C). Cows in group T1 received this preparation 21 days before calving and on calving day, and cows in group T2 received it only on calving day. The cows in the control group did not receive this preparation. Supplementation with Se increased Se serum levels of cows treated at calving day (p<0.05). Differences in milk yield at all weeks and the electrical conductivity values at the 8th and 12th weeks were significant (p<0.05). Supplementation with Se and Vitamin E decreased the incidence of metritis, the number of services per conception and the service period, but had no effects on the incidence of retained fetal membrane. A partial budgeting analysis indicated that Se supplementation was economically profitable; cows in group T1 averaged 240.6$ per cow, those in group T2 averaged 224.6$ per cow. Supplementation with Se and Vitamin E has been found to increase serum Se levels, milk yield, and has positive effects on udder health by decreasing milk conductivity values and incidence of sub-clinical mastitis.

이 연구에서는 장기미집행 도시공원 및 녹지 토지보상 재원마련을 위한 지방채 발행의 타당성을 검토하였고, 지방채를 발행하여 지가 상승이 높은 지역을 우선보상할 것을 제안하였다. 이를 위해 장기미집행 도시공원 및 녹지 32개소를 대상으로 상관분석과 부분최소제곱(Partial Least Square: PLS) 회귀분석을 실시함으로써 '7년간 개별공시지가 상승가'에 영향을 미치는 요인을 규명하였다. PLS 회귀분석의 투영시 변수 중요도 값은 '기준년도 개별공시지가(1.919)', '해당 자치구 누적상승률(1.176)' 순으로 높았다. 본 연구의 시사점은 다음과 같다. 지난 12년간 서울의 평균개별공시지가 누적상승률이 지방채 누적이자율보다 더 높다는 것은 지방채 발행으로 지급해야 하는 이자보다 개별공시지가가 더 많이 올랐다는 것을 의미한다. 더구나 실보상가는 개별공시지가의 3배 정도 되므로, 실제로는 지급이자액보다 훨씬 더 많은 지가 상승이 이루어졌을 것이다. 이는 지방채를 발행하여 지가상승이 높은 지역과 같은 보상우선대상지를 선매수하는 것이 예산집행에 있어서 경제성과 효율성을 높일 수 있음을 보여준다. 또한 예산집행의 경제적 효율성을 위하여, 지가 상승이 높을 것으로 예상되는 '개별공시지가가 높은 곳', '지가 상승이 높은 자치구에 속한 곳'을 우선보상 기준항목으로 선정하는 것이 필요함을 보여준다. 앞으로, 장기미집행 도시공원 및 녹지 토지보상을 위해서 지방채를 발행할 경우, 지방채 상환재원 마련방안에 대한 다양한 연구도 함께 진행되어야 할 것이다.

The objective of this study was to analyze dietitians' sanitary practices and perceptions of obstacles according to HACCP. Questionnaires were administered to 94 elementary school dietitians in the Gwangju and Jeonnam Regions of South Korea. The data were evaluated by a 5 scale Likert method and statistically analyzed The results of the study are as follows. Each subject was generally characterized as a university graduate 79.8%, with 10 to 15 years experience 37.6%, and in her mid to late thirties 39.4%. We found that direct management was the highest occurring form of food service system 96.8%. With regards to the type of food service operation quantitative service as 60.6%, and partial self-service was 30.9%, 89.4%of all served only lunch. In all, 93.6% of the teams collaborated, while their organic collaboration was 64.9%. When HACCP was applied, sanitary practices scored an average of 4.83, which was significantly higher than 4.62 when HACCP was not applied. The dietitians' perception of sanitary practices was as very high 4.75 of 5. Sanitation, in regards to food management, scored 4.89 among the detailed items. This proves that in relation to food management, sanitation is considered most important. When HACCP was not applied, the perception of obstacles was, on an average, 3.07, which was higher than 2.74 when HACCP was applied. The results for the detailed items, which focused on sanitary practices and different perceptions of obstacles according to HACCP, were as follows. When HACCP was applied, a high mean of 3.32 occurred for facilities and utilities shortages followed by degree of cooperation at 3.22, and then monitoring at 3.01. The item that dietitians viewed as the biggest obstacle was lack of departmental budget support (M=3.46). Other serious obstacles were facilities, facility sanitation, and utility shortages (M=3.38), as well as the aappropriateness of machines and cooking utensils and arrangements in the dining room (M=3.28). Stepwise multiple regression was used to better understand how much these perceptions of obstacles would influence sanitary practices when HACCP was applied. The item analysis of the HACCP obstacles proved that persons involved in food service, except the food service employees, didn't cooperate enough with their food service employees. As a result, this lack of cooperation had a negative effect on sanitary practices. Accordingly, it is necessary to determine the causes of for lack of cooperation and attract the active attention of those involved.
