  • This study was conducted to investigate the effects of feeding patterns of concentrates on growth performance, blood parameters and carcass characteristics in Hanwoo cows. Randomly-allocated groups, restricted concentrate feeding (T1), restricted concentrate feeding for 6 months and ad libitum 2 months (T2), restricted concentrate feeding for 4 months and ad libitum 4 months (T3), were contained with 9 animals. According to feeding patterns of concentrate, growth performance was not significantly different among the treatment groups. However, ADG tended to be higher in T2 group (0.75 kg/d) compared to the other groups (T1: 0.62 kg/d, T3: 0.72 kg/d). DMI was not significantly different among the treatment groups, interestingly, rice straw intake was significantly higher in T1 group compared with others (p<0.05). There were significant difference among feed conversion ratio, which are 17.8, 12.8, and 14.1 kg for T1, T2, and T3 (p<0.05), respectively. The serum level of albumin, triglyceride, glucose and GPT were greater in T3 group compared to other groups at fattening 6 to 8 months (p<0.05). The results of yield traits, carcass weight, back fat thickness and rib eye area were not differ among treatment groups, but yield index was significantly greater in T2 group compared to T1 group (p<0.05). The 'A' appearance rate (%) of meat yield grade was highest in T2 group for 78%. The marbling score, meat color, fat color, texture and maturity in quality traits were not differ among the treatment groups. However, marbling score and appearance rate (%) of over 1st meat quality grade were tend to be increased at T3 rather (4.0, 56%) group compared with other groups (T1: 3.4, 56%; T2: 3.6, 33%). Thus, the present study suggested that restricted concentrate feeding (1.6% of BW) for 4 months during early fattening periods and ad libitum feeding for 4 months during late fattening periods are recommendable.

  • Twenty male crossbred calves of about one year of age (average body weight, 196 kg) were distributed in four equal groups following complete randomized design. Wheat bran was supplemented to four different combinations of wheat straw and green fodder (Sorghum vulgare) at 40:60, 30:70, 20:80 and 10:90 ratios (on as fed basis) for the feeding of animals in Group 1, 2, 3 and 4, respectively. The feeding trial was continued for a period of 70 days including one metabolism trial of 6 days collection of feed, faeces and urine sample to determine the intake and utilization of nutrients. The intakes (g/kg $W^{0.75}$) of DM, TDN and CP were $93.0{\pm}1.8$, $55.5{\pm}1.1$ and $9.51{\pm}0.18$ in Group 1; $98.0{\pm}1.8$, $59.6{\pm}1.1$ and $10.33{\pm}0.19$ in Group 2; $98.1{\pm}2.4$, $60.5{\pm}1.5$ and $10.79{\pm}0.26$ in Group 3; and $97.7{\pm}1.7$, $59.1{\pm}1.0$ and $10.78{\pm}0.19$ in Group 4, respectively. The digestibility of nutrients did not differ significantly among the groups. Relatively higher nutrient intake and balances of nitrogen reflected non-significantly high her live weight gain in the later three groups (436, 439 and 464 g, respectively) as compared to Group 1 (400 g). The DM intake remained unchanged by increasing the proportion of green fodder beyond 20:80 ratio and thus was assessed to be satisfactory for optimum productivity in animals.

  • Objective: An experiment was conducted to study the effect of a blend of essential oils (BEO) on enteric methane emission and growth performance of buffaloes (Bubalus bubalis). Methods: Twenty one growing male buffaloes (average body weight of $279{\pm}9.3kg$) were divided in to three groups. The animals of all the three groups were fed on a ration consisting of wheat straw and concentrate mixture targeting 500 g daily live weight gain. The three dietary groups were; Group 1, control without additive; Group 2 and 3, supplemented with BEO at 0.15 and 0.30 mL/kg of dry matter intake (DMI), respectively. Results: During six months feeding trial, the intake and digestibility of dry matter and nutrients (organic matter, crude protein, ether extract, neutral detergent fibre, and acid detergent fibre) were similar in all the groups. The average body weight gain was tended to improve (p = 0.084) in Group 2 and Group 3 as compared to control animals. Feeding of BEO did not affect feed conversion efficiency of the animals. The calves of all the three groups were in positive nitrogen balance with no difference in nitrogen metabolism. During respiration chamber studies the methane production (L/kg DMI and L/kg digestible dry matter intake was significantly (p<0.001) lower in Group 2 and Group 3 as compared to control animals. Conclusion: The results indicated that the BEO tested in the present study have shown potential to reduce enteric methane production without compromising the nutrient utilization and animal performance and could be further explored for its use as feed additive to mitigate enteric methane production in livestock.

  • BACKGROUND/OBJECTIVES: Thin children may have insufficient intake of energy and nutrients, resulting in reduced immune function and growth. This study aimed to identify the effects of multiple herb formula SEC-22 supplementation on growth, dietary changes, and picky eating behaviors in thin children. SUBJECTS/METHODS: A double-blind, randomized clinical trial was conducted on 79 children aged 2-5 years with poor appetites, BMI percentile < 25, and without any illness. Subjects were given either SEC-22 (n = 35) or placebo (n = 44) for 2 months and followed for an additional 2 months. Three-day dietary records, questionnaires on picky eating behaviors, and anthropometric measures were collected. RESULTS: Energy, carbohydrate intake, and feeding difficulty improved in both groups during the intervention period. However, changes were maintained only in the SEC-22 group after 2 months of follow-up post-supplementation. 'Frequency of trying to feed' was improved in the SEC-22 group compared to the placebo group after the first month of follow-up (P < 0.05). Intakes of potassium and thiamine were improved in the SEC-22 group compared to the placebo group after the first month of intervention (P < 0.05). 'Frequency of food reward', eating amount, and intakes of carbohydrate, potassium, and vitamin C showed significant improvement compared to the placebo group after the second month of follow-up (P < 0.05). CONCLUSIONS: These results suggest that SEC-22 supplementation can improve parental feeding difficulty resulting from insufficient eating amount or picky eating as well as increase nutrient intake in thin children. Although these improvements were observable at least 2 months after supplementation, effects beyond this time frame need to be confirmed.

  • The present research was designed to evaluate the effects of pre and post-partum energy level and feeding pattern on the performance of crossbred dairy cows and their calves under farm conditions. A total of 16 crossbred dairy cows were divided into two equal groups on the basis of their body weight and milk production. One group was given 30% less and the another was given 30% more energy than MAFF's (1984) recommendation. After calving all cows were given same ad.libitum diet to assess the effects of feeding during pregnancy on their performance. It was observed that just before calving cows on low energy group gained less (p<0.05) weight than that of the cows on high energy group (12.9$\pm$11.71 vs. 42.25$\pm$12.74 kg/cow. Birth weight of calves of low energy group was lower (p<0.05) than that of the calves of high energy group (17.87$\pm$1.78 vs. 20.73$\pm$2.24 kg/calf). Cows that were on low pre-calving dietary energy level produced less milk during lactation than the cows of high energy pre-calving group (3.45$\pm$0.75 vs. 4.27$\pm$0.79 lit./cow). No significant difference was noticed on calf growth rate and reproductive parameters of cow. Energy level that was 30 % less than MAFF's (1984) recommendation was found to be very low and not suitable for our crossbred cows during their last three months of pregnancy.

  • An experiment was conducted on crossbred male calves to study the effect of arsenic (As) on immunity status and certain hematological parameters. Ten crossbred male calves of 3-4 months of age were distributed into two equal groups. Group I was kept as control, whereas, group II was supplemented daily with 50 ppm As (as $As_sO_3$) up to 90 days, in the diet. Calves of both groups were fed as per ICAR standards and their requirements were fulfilled by feeding concentrate mixture and green oats. All calves were kept under similar managemental conditions. Blood samples were collected at fortnightly intervals to estimate various haematological parameters and superoxide dismutase (SOD) enzyme activity. Serum Ig and serum glutamic pyruvate transaminase (SGPT) were also measured. Cell-mediated immune responses of the calves were monitored at 0, 45 and 90 of experimental feeding, through lymphocyte proliferation. No change in blood total leukocyte counts (TLC), differential leukocyte counts (DLC), packed cell volume (PCV), haemoglobin (Hb) and SGPT was observed with As supplementation. A decrease in SOD activity was noticed in group II calves. Stimulation index (SI) for lymphocyte proliferation decreased from 1.14 to 0.79 in group II calves during 90 days experimental feeding, whereas, there was no change in SI values in group I indicating significant decrease in immune response of As supplemented calves. Blood As concentration increased in group II calves with the decrease in immune response. Short term supplementation of As to growing calves suggested suppressive effects on cell-mediated immunity. However, long term experiments are required to demonstrate clearly the efects of this toxic metal in calves.

  • One of the treatment methods for maxillary cancers or infections in maxilla is maxillectomy. Palatal defect can be resulted from this operation and it may cause functional problems with swallowing and speech, and psychological problems of patients. After maxillectomy, as rehabilitation, there can be two options. One is a prosthodontic treatment using obturator and the other is surgical reconstruction of defect with graft. As both methods have advantages and disadvantages, in determining treatment method after maxillectomy, various factors have to be considered. The purpose of this study is to compare the prosthodontic group to surgical group after maxillectomy with elapsed days prior to commencement of postoperative oral feeding, and to analyze the results of prosthodontic treatment and surgical treatment. During the period from March of 2000 to June of 2006, 74 patients were treatment by prosthodontic methods for maxillary defect. Among these patients, patients who had only velopharyngeal deficiency after surgery, whose data were incomplete, whose causes of palatal defect were not the treatment of diseases in maxilla, and who already had palatal defect due to previous surgery were excluded in this study. The patients who underwent maxillectomy for the treatment of diseases in the maxilla and were treated immediately after operation using surgical reconstruction or prosthodontic rehabilitation were included in this study. The records of 43 patients were reviewed to compare and to analyze the prosthodontic treatment and surgical reconstruction after maxillectomy. The median of days elapsed prior to commencement of postoperative oral feeding in the prosthodontic group was compared with data of surgical group. The data was analyzed using the Mann-Whitney test (${\alpha}$=.05). Days elapsed prior to postoperative oral feeding commencement in the prosthodontic group were less than those in the surgical group.

  • The purpose of this research was to study the effects of the feeding of dietary citrus byproducts on the physicochemical properties and palatability of Hanwoo rump (HR). The samples for experimental samples consisted of the HR not fed without citrus byproducts pulp (CBP-0) and the HR rump fed with citrus byproducts pulp during the fattening period (CBP-1). The control (CBP-0) HR rump was fed by general practical feeding (roughages and concentrates were fed separately), while the CBP-1 was fed in the same manners as CBP-0 until 17 months but with citrus byproducts then fed fer the next 10 months. There were no significant differences in the $L^*$ (tightness), $a^*$ (redness) and $b^*$ (yellowness) of the HR between the CBP-0 and CBP-1 fed groups. There were no significant differences in the pH, VBN content and EDA between the samples, but the TBARS value of the CBP-1 fed group was lower than that of the CBP-0 fed group (p<0.05). There were no significant differences in the water holding capacity, freezing loss, thawing loss, boiling and roasting logs between the CBP-0 and CBP-1 fed groups. There were no significant differences in the hardness, cohesiveness, chewiness and shear force between the samples, but the springiness of the CBP-1 fed group was higher than that of the CBP-0 fed group (p<0.05). There were no significant differences in the sensory scores for the roasted beef between the CBP-0 and CBP-1 fed groups. There were no significant differences in the taste, flavor, juiciness and palatability of roasted beef the between samples, but the tenderness of the CBP-1 fed group was superior to that of the CBP-0 fed group.

  • The experiment was conducted to study the effect of supplementary urea molasses block lick with rice straw based diet on the performance of sheep. Six indigenous sheep of about two years of age with an average body weight of 12.88 kg, were selected for this experiment They grouped into two by stratified randomization, and the experiment was conducted for a period of 90 days. Sheep of group A was fed rice straw and group B was feed rice straw with urea molasses block lick, beside this both the groups received 66 g wheat bran and 167 g of Ipil-Ipil leaf meat. The study revealed that the average daily gain of live weight per sheep per day was 41 gm and 70 gm in group-A and group-B respectively. From the analysis of variance it was evident that live weight gain in sheep of group B, supplemented with urea molasses block lick was highly significant (p < 0.01). It was also estimated that group A required 8.12 kg DM to gain 1 kg live weight, whereas group B receiving urea molasses block lick required 5.30 kg DM to gain 1 kg live weight. Therefore, feeding rice straw with urea molasses block lick able to utilize more crop-residues efficiently.

  • The male rats after weaning were fed with the mixed diets of rice and some cereals for three weeks in a ad-libitum method. The growthgain of rats were determined by feeding those diets and the contents of free basic amino acids level in plasma were analyzed by amino acid analyzer. The results were as follows; 1. Rice diets group was highest in growthgain and weightgain, the second was the mixed of 80% rice-20% barley, and the last was the 80% rice-20% wheat group. 2. It was similar in the contents of plasma free basic amino acids of every diet group. The contents of Lys was highest and Arg, His were low in order. The mixed diet of 80% rice-20% barley group was higher than the rice only diet group in the contents of Lys and His. but rice only group was highest in Arg. The mixed of 80% rice-20% wheat diet group was lowest in the contents of Lys, His, Arg. Therefore feeding mixed diets of rice and cereals. the contents of Lys was highest, the second was Arg and the last was His in the plasma free basic amino acids level.
