An exploratory survey was performed to assess the present status of distribution and production of coconut palm (Cocos nucifera Linn.) in the rural landscape of Meghna floodplain of Bangladesh. A multistage simple random sampling technique was adopted to identify the study area and respondents. A total of 50 households were selected randomly for the study. Traditional knowledge on cultivation, management, and production of coconut palm was emphasized. Marketing of coconut palm products and income derived from coconut palm cultivation was taken into consideration. Perceptions of farmers, traders and professionals were described in due context of opportunities and constraints of coconut palm cultivation. Coconut palm cultivation was found to play an important role in household economy in rural Bangladesh sharing considerable contribution to the total income. About 10% of their total annual income was reported to come from coconut husbandry. Highest number of the coconut palms, 24%, was found to grow in the homestead compounds and in the pond banks. About one-third lands of the households were found to be covered by the coconut palms. Maximum, 19%, coconut palms were found in the 16-20 years age-class. Production of coconut was found highest at the age-class 11-15 years. The study found some important opportunities and constraints of coconut farming in rural Meghna floodplain area of Bangladesh. The results of this study would be useful for the rural development practitioners in Bangladesh.

The objective of this study was to evaluate the in vitro effects of coconut materials on ruminal methanogenesis and fermentation characteristics, in particular their effectiveness for mitigating ruminal methanogenesis. Fistulated Holstein cows were used as the donor of rumen fluid. Coconut materials were added to an in vitro fermentation incubated with rumen fluid-buffer mixture and timothy substrate for 24 h incubation. Total gas production, gas profiles, total volatile fatty acids (tVFAs) and the ruminal methanogens diversity were measured. Although gas profiles in added coconut oil and coconut powder were not significantly different, in vitro ruminal methane production was decreased with the level of reduction between 15% and 19% as compared to control, respectively. Coconut oil and coconut powder also inhibited gas production. The tVFAs concentration was increased by coconut materials, but was not affected significantly as compared to control. Acetate concentration was significantly lower (p<0.05), while propionate was significantly higher (p<0.05) by addition of the coconut materials than that of the control. The acetate:propionate ratio was significantly lowered with addition of coconut oil and coconut powder (p<0.05). The methanogens and ciliate-associated methanogens in all added coconut materials were shown to decrease as compared with control. This study showed that ciliate-associated methanogens diversity was reduced by more than 50% in both coconut oil and coconut powder treatments. In conclusion, these results indicate that coconut powder is a potential agent for decreasing in vitro ruminal methane production and as effective as coconut oil.

Almost 1/4 of all the coconuts in the world is produced in the Philippines. During periods of high supply of coconuts it would be better to feed coconut meat to farm animals for conversion into meat and eggs. Three studies were conducted at the Visayas State College of Agriculture, Baybay, Leyte, Philippines from April, 1983 to April, 1985 to determine the response of Mallard ducks, Muscovy ducks and broilers to fresh coconut meat supplementation in their diets. Results showed that Mallard ducks on ration with coconut meat performed similarly with those on ration without coconut meat. Feed cost per dozen eggs was reduced by 28-30% with coconut meat. Feed cost per unit gain of muscovy ducks was reduced by 32-37% by coconut meat supplementation. With broilers, feed conversion, gain in weight and breast weight were significantly improved by coconut meat supplementation. Return-above-feed cost increased with increasing level of coconut meat in the ration.

This study examined the changes in the mechanical properties of coral concrete under different coconut fiber admixtures. To accomplish this goal, the compressive strength, splitting tensile strength, flexural strength and elastic modulus properties of coral concrete blocks reinforced with coconut fibers were measured. The results showed that the addition of coconut fiber had little effect on the cube and axial compressive strengths. With increasing coconut fiber content, the flexural strength and splitting tensile strength of the concrete changed substantially, first by increasing and then by decreasing, with maximum increases of 36.0% and 12.8%, respectively; additionally, the addition of coconut fibers resulted in a failure type with some ductility. When the coconut fiber-reinforced coral concrete was 7 days old, it reached approximately 74% of its maximum strength. The addition of coconut fiber did not affect the early strength of the coral concrete mixed with seawater. When the amount of coconut fiber was no more than 3 kg/m3, the resulting concrete elastic modulus decreased only slightly from that of a similar concrete without coconut fiber, and the maximum decrease was 5.4%. The optimal dose of coconut fiber was 3 kg/m3 in this study.

This study examined the quality characteristics of waffles made with coconut extract. Waffles were prepared with the substitution of 25, 50, 75, 100, and 125% of coconut extract. The viscosity of the batter tended to increase with increasing ratio of coconut extract, whereas the spreadability measures were not changed significantly. The baking loss rates tended to increase with increasing ratio of coconut extract while the moisture contents were not changed significantly. The L-value and b-value decreased but the a-value increased. TPA showed that the hardness, springiness, chewiness, cohesiveness, and gumminess tend to increase with increasing amount of coconut extract while the resilience was not changed significantly. The results of the sensory evaluation showed that waffles made with 100% coconut extract were the most preferable in appearance, flavor, taste, texture, and overall acceptability.

This study investigated the quality characteristics of waffles added with coconut powder. Coconut powder was substituted into waffles at 0, 5, 10, 15, 20, and 25% weight amounts based on the total weight of wheat flour. The viscosity of batter tended to increase as the ratio of coconut powder increased whereas the measures of spreadability were not significantly changed. Baking loss rates tended to increase as the ratio of coconut powder increased while moisture contents were not significantly changed. The L-value and b-values decreased gradually while a-value increased. Among the textural characteristics hardness, springiness, chewiness, and gumminess tended to increase in proportion to the amount of coconut powder while cohesiveness and resilience were not significantly changed. The results of the sensory evaluation show that waffles made with 20% coconut powder were the most preferable in appearance, flavor, taste, texture, and overall acceptability.

본 실험은 딸기 조직배양 시 증식률 향상을 위해 coconut water의 적정처리 농도 구명하고자 실시하였다. 본 실험에 사용된 시험 품종은 '매향'이며, BA 0.5 mg·L^-1와 IBA 0.1 mg·L^-1을 혼합처리한 배지에 coconut water를 0, 20, 40, 60, 80, 100 ml·L^-1로 첨가하여 실험하였다. Coconut water 처리 시 형태적 변이검정과 SSR 검정을 통해 변이 발생 유무를 확인하였다. '매향'은 무처리에 비해 coconut water 처리에서 증식률이 향상되었으며, 특히 coconut water 100 ml·L^-1 처리에서 증식률이 약 4배 향상되었다. '매향'에 coconut water 100 ml·L^-1 처리 시 형태적 변이체가 2개체 발생하였으나 유전적 차이는 보이지 않았다. 따라서 '매향' 조직배양 시 coconut water 100 ml·L^-1를 처리하면 유전적 변이없이 대량증식이 가능할 것으로 판단된다.

Objectives: We analyzed the relative beneficial impacts of probiotics and coconut oil-based mouth rinses on oral health. Methods : A total of 33 subjects were enrolled and randomly assigned to three groups. Coconut oil and probiotics were given to the experimental group, and distilled water to the control group. We evaluated the possession site of Gingival index, CPITN index, BOP, Pocket depth, and PHP index. Results: In the coconut oil and probiotic groups, Gingival index significantly decreased on both days 15 and 30. CPITN significantly decreased on days 15 and 30 in the coconut oil group (p<0.01), and on day 30 in the probiotic group (p=0.002). There was a significant interaction between group and time for BOP and PHP index (p<0.001), and the coconut oil group was more effective in improving BOP and PHP index. Conclusions: The above results showed that the mediation effect of coconut oil and probiotics was more effective with coconut oil.
