The present study was conducted to examine the feasibility of utilising bamboo (Bambusa arundinacea) shoot shell (BSS) in ruminants. Chemical composition, rumen degradability and some antinutritional compounds were determined for fresh and boiled BSSs to evaluate its feed value and safety. Thirty-two Holstein heifers were allocated to four groups and used to investigate the response in growth rate to supplementing ammoniated rice straw with fresh shell (phase 1) or silage of boiled BSS (phase 2). All animals were offered ammoniated straw ad libitum with 1kg of cotton seed meal (phase 1) or 0.5 kg of cotton seed meal and 0.5 kg of concentrate mixture (phase 2) per head per day. The BSS was supplemented at levels of 0, 3, 6 or 9 kg/d (phase 1) and 0, 5, 10 or 15 kg/d (phase 2) (as fed basis). The BSS was very high in moisture content, and its contents of crude protein and neutral detergent fiber were 13~16% DM and 65~76% DM, respectively; boiling resulting in higher moisture and protein. No hydrocyanic acid was detected in both BSSs and content of tannins was negligible. Rumen degradability of BSS was reasonably high, and with boiling the rapidly degradable fraction decreased, and potentially degradable component increased. Silage of the boiled BSS was slightly lower in both rapidly and slowly degraded fractions than the fresh BSS. Animals consumed all supplemented BSSs without any adverse health problems. Intake of ammoniated straw decreased with the increasing levels of BSS, but total intake was higher in almost all supplementary groups than in the non-BSS. Heifers had a higher growth rate in phase 1 with fresh BSS than in phase 2 with ensiled shell, and daily weight gains were 622, 629, 744 or 690 g in phase 1, and 578, 575, 677 or 635 g in phase 2 at four BSS levels, respectively. For both phases growth rate was significantly higher for the animals in groups 3 and 4 than those in groups 1 and 2 (p<0.01), with little difference between groups 1 and 2 (p>0.05) but significant difference between groups 3 and 4 (p<0.05). Supplementation with BSS also resulted in an improved feed conversion rate, with the least concentrate consumption in group 3 for both phases. It is concluded that the BSS has a high potential nutritional value as indicated by its medium protein content, reasonably high rumen degradability, and that inclusion of BSS in ammoniated rice straw diet is not only safe to animals, but also may improve growth rate of ruminants and feed conversion rate. It may be disadvantageous to use high amounts of BSS in ammoniated straw diets.

난황 항체 강화를 위하여 켈프밀 $4\%$ 처리구와 계피 $0.3\%$와 박하 $2\%$가 첨가된 특수사료를 급여하고 Streptococcus mutans를 2주 간격의 5회 면역처리를 복합적으로 실시하면서 40주령 산란계를 사양하였다. 면역처리를 하지 않은 처리군에서는 박하 첨가군의 산란율이 높았다. 면역한 후에 발생되는 산란율 저하는 대조구와 계피 첨가군에서 적게 나타났다. 계란의 무게는 면역처리에 따른 효과가 나타나지 않았으나 사료에 따라 차이가 나타났다. 면역처리를 하지 않은 처리구에서 계피, 박하, 켈프밀 모두 총 IgY 함량이 대조구보다 높게 나왔으며, 특히 켈프밀의 경우 대조구에 비해 $5.4\%$ 가량 상승하였다. 면역 한 처리구끼리 각각 비교하여 보면 대조구에 비해서 다른 처리구에서 모두 높았으며, 특히 켈프밀 처리구가 월등히 높아 대조구에 비해 $7.9\%$ 정도의 상승이 있었다. S. mutans로 면역처리된 닭으로부터 얻은 계란에서의 충치균에 대한 특이(specific) 총 IgY 함량을 분석한 결과, 항충치균 IgY는 1차 면역하고 4주정도 후에 나타나기 시작하였다. 마지막 immunization후 5주 이상 경과하더라도 specific IgY의 양이 상당히 높은 수준을 유지하는 것을 볼 수 있었다. 총 실험기간 동안의 specific IgY 함량의 평균을 보면 켈프밀 처리구는 다른 식이에서 보다 훨씬 높은 specific IgY 역가 보여주었고 대조구에 비해 특이 항체가 약 $8.5\%$ 가량 증가되어 켈프밀의 첨가는 면역처리를 통한 특수 IgY 생산에 효과적임을 나타내었다

This study was proposed to investigate effects of inclusion of Chinese milk vetch silage (MVS) and rapeseed meal (RSM) on the growth and rumen fermentation of Hu-sheep. Fifty weanling lambs were randomly divided into five equal groups and offered ammoniated rice straw (ABRS) ad libitum along with 100 g concentrate (Trial 1). The animals in $T_0$, $T_1$, $T_2$, $T_3$ and $T_4$ group were respectively supplemented with MVS at levels of 0, 0, 7, 14 or 21% and with RSM at levels of 0, 15, 10, 5 or 0%. Daily gain of lambs was significantly (p<0.05) higher in $T_1$, $T_2$ and $T_3$ group than that in $T_0$ and $T_4$ group. Feed conversion ratio was greatly reduced in supplemented groups as compared with $T_0$ group. In trial 2, five sheep with rumen cannulae were used in a $5{\times}5$ Latin square design. The experimental treatments were as described in Trial 1, but without concentrate. The intake of AVRS was significantly (p<0.05) lower in $T_4$ group than that in $T_0$ group, and also significantly (p<0.05) lower than those in $T_1$ and $T_2$ group. Little difference among all treatments was found in 48h DM degradability of ABRS, MVS and RSM, and in rumen pH value and microbial protein concentration. Rumen concentrations of individual and total VFA tended to be higher in supplemented groups than those in $T_0$ group.These rusults suggest that supplementation with RSM or RSM plus MVS can effectively improve the performance of lambs, and may fail to influence markedly the rumen digestion of ABRS and rumen environments.

BACKGROUND/OBJECTIVES: This study was conducted to examine disparities in food and nutrient intakes based on family types identified among 1,856 participants who were the Korean elderly people in the 6th Korea National Health and Nutrition Examination Survey (KNHNES) excluding those who were currently practicing the diet therapy. SUBJECTS/METHODS: We separated the subjects into two groups: living alone (LA, n = 638) and living with a spouse (LS, n = 1,218). We also examined the disparities of dietary quantity and quality of those two groups using complex sampling design general linear regression analyses (CS GLM). RESULTS: In the LA group, there was a higher percentage of females and average age in LA group was higher than the participants in the LS group. Household income and education level were significantly lower in LA compared to those of LS. The frequencies of skipping meals were higher in LA. LA's food and nutrient intakes showed lower consumption of vegetables, fruits, seaweeds, and of most nutrients. Even after adjusting for the confounding factors, the consumption of vegetables, seaweeds, carbohydrates, potassium, riboflavin, and vitamin C showed lower in LA than LS. Moreover, LA's nutrient intake ratios compared to the KDRIs were lower which turned out to be similar to their nutrient intakes. CONCLUSIONS: These results show that dietary behavior and food intake of the elderly are associated with family types. Frequently skipping meals and less dietary variety are more common with elderly persons who were living alone. Therefore, it is necessary to integrate the supplementary food programs and nutrition education programs for the elderly living alone.

Objective: This experiment was studied the effects of various levels of crude glycerin (CG) in dairy goat diet on daily intake, milk yield, milk composition, some physical properties and some quality changes of goat milk after sterilization. Methods: Twelve 75% Saanen dairy goats (body weight = $49{\pm}3kg$; days in milk = $60{\pm}12d$) were randomly assigned in a completely randomized design to evaluate the effects of three experimental diets consisting of 0%, 5%, and 10% CG (dry matter basis) which were formulated to meet or exceed the nutrient requirements of goats. Experimental dairy goats were evaluated for feed and milk yield. Milk samples were analyzed for their composition, including fatty acids, casein profile, fat globule size, and color, and were sterilized to evaluate milk heat stability. Results: There were no significant differences between 0% and 5% CG treatments infeed. Increasing CG supplementation from 0% to 5% increased milk yield from $2.38{\pm}0.12$ to $2.64{\pm}0.23kg/goat/d$. In addition, milk samples from 5% CG treatment had the highest total solids, fat content and lactose content, and largest fat globule size. Increasing CG to 10% resulted in a decrease in milk fat. After sterilizing at $116^{\circ}C$, $F_0=3min$, goat milk samples from 5% CG treatment had slightly higher sediment content and comparatively higher degree of browning. Conclusion: Considering milk yield, milk fat content and quality of sterilized milk, 5% CG supplementation in a total mixed ration has a potential for implementation in dairy goats.

Vitamin E has been applied as a dietary supplement or post mortem to meat cuts to preserve meat quality and extend shelf life. This study was conducted to determine the effects of supplementation of the diet of Hanwoo steers with Economas $E^{(R)}$, a less expensive alternative to vitamin E, on meat quality preservation. To accomplish this, 36 Hanwoo steers were randomly allotted into three treatment groups ; no additive (control), Economas $E^{(R)}$(T1) and vitamin E (T2). Vitamin E and Economas $E^{(R)}$ were included in the diets at 500 mg/head and 200 mg/head, respectively, for 5 months. Evaluation of carcass performance parameters immediately after slaughter revealed no treatment effects (P>0.05). Samples collected from the loin area and stored at $4^{\circ}C$ for up to 9 days showed that T1 and T2 preserved pigment and lipid stability as indicated by significantly (P<0.05) higher CIE $L^*$ and lower CIE $a^*$ and CIE $b^*$ values and a less rapid increase in thiobarbituric acid reactive substance (TBARS) relative to the control. However, treatments had no effect (P>0.05) on cholesterol and fatty acid content in meat. Based on these findings, Economas $E^{(R)}$ provided at 200 mg/head is as effective as vitamin E applied at 500 mg/head at preserving Hanwoo meat quality over a 9 day storage period at $4^{\circ}C$.

This study was conducted on sows to evaluate the effect of flaxseed oil on the sows and their offspring's performance. Forty-eight (48) sows (Landrace × Yorkshire) and their offspring were assigned randomly to each treatment (Control and Control + flaxseed oil 0.5% [FX]). Body weight (BW), average daily feed intake (ADFI) and nutrient digestibility of the sows were estimated. Sow backfat thickness, days-to-estrus, and chest circumference were measured by different methods. In piglets, survival rate, the initial weight, weaning weight, and average daily gain (ADG) were calculated. Fecal scores of both the sows and piglets were recorded. Inclusion of FX did not influence (p > 0.05) the litter size, days-to-estrus, sow BW, ADFI and digestibility of nutrient throughout the experiment. Reduction in (p < 0.05) BW loss was observed with the FX supplementation in sows. Only the backfat thickness during the weaning period showed an increase (p < 0.05) by FX supplementation. Chest circumference was decreased (p < 0.05) in the FX group compared to the control. Sows fed the FX diet had a reduced (p < 0.05) fecal score only at weaning. Piglets' fecal score showed no significant differences for FX supplementation. However, the inclusion of FX brought about a higher (p < 0.05) birth weight, weaning weight, and average daily gain (ADG). In conclusion, our study suggests that FX has positive supplementary effects on a sow's body condition and its offspring's performance as a source of n-3 fatty acid.

Objective: This study investigated the effects of soapnut (Sapindus mukorossi) shell powder (SSP) on serum hormone level, egg quality, semen characteristics and reproductive performance of broiler breeders fed with a maize-soybean meal based diet. Methods: Ninety six female and twenty four male CARIBRO-VISHAL broiler breeders, 38-week old, were individually caged and randomly allocated to four treatment groups (24 female breeders/treatment and 6 male breeders/treatment): an un-supplemented control (T1) and three groups with 0.0176% SSP (group T2), 0.026% SSP (group T3) and 0.0528% SSP (group T4), to have supplementary saponin at 0, 50, 75, and 150 ppm, respectively, for 42 days. Results: The results indicated that serum (p<0.001) and seminal plasma (p<0.05) testosterone level, semen volume (p<0.001), mass motility (p<0.001), and live spermatozoa count (p<0.001) was increased in groups T3 and T4 compared to T2 and control groups. Compared with control group, total sperm count was increased (p<0.001) and dead spermatozoa count was decreased (p<0.001) in SSP supplemented groups. Supplementation of SSP did not affected the quality of egg lay. Compared with control group, fertility (p<0.01) and hatchability (total eggs set and fertile eggs set) (p<0.001) were significantly improved in SSP supplemented groups with the highest improvement in T3 treatment group. Embryonic death was decreased (p<0.001) in SSP supplemented groups compared to control; lowest embryonic death was recorded in T3 treatment group. Conclusion: Thus, it was concluded that dietary supplementation of 0.026% SSP (saponin equivalent 75 ppm) improved the reproductive performance of broiler breeders.

The effects of different mineral supplementations on the milk yield of free-ranging Somali camels were investigated in two phases in a semi-arid region of northern Kenya during the dry and wet seasons in 2002 and 2003. In phase 1, twelve (12) lactating camels were selected at random to form four (4) groups each consisting of three camels. The first group served as the control and as a result received no mineral supplementation. In addition to the control diet the other groups received oral doses of minerals as follows over a 60-day period: T1 (P), T2 (High Cu low Co) and T3 (Low Cu high Co). The daily milk yield and blood mineral profiles were measured during the wet and dry seasons. The mean daily milk yield increased from 3.4 L/d to $4.3{\pm}0.3L/d$ and 5.2 L/d in the dry and wet seasons, respectively. Fifteen (15) lactating camels were selected at random to form five groups each consisting of three replicates. The control group did not receive any mineral supplement. The other four groups in addition to the control diet, received the following treatments: T4 (Common Salt), T5 (High Co), T6 (High Co+P) and T7 (Low Co+P). Mineral supplement T6 produced significantly higher milk yield ($5.4{\pm}0.5$ and $6.5{\pm}0.7L/d$) during the dry and wet seasons. Both T6 and T7 had significantly higher milk yield than T4 and T5. During both phases, the blood Ca and P level significantly increased in camels receiving T1, 6 and 7. Animals that received only the trace mineral supplements had lower blood P compared to the ones receiving supplementary P and also the control. Supplementation of lactating camels with Co and P significantly (p<0.05) increased milk yield). Effect of common salt, commonly given by farmers, on milk yield was insignificant. It was concluded that mineral supplementation to lactating camels was beneficial, and that mineral supplements should include P and Co. Further research is required to establish P and Co requirements of lactating camels.
