“…Asam lemak siklopropenoat ini pada umumnya menyebabkan berbagai efek negatif yang merugikan baik secara ekonomis maupun produksi, terutama bila semakin meningkat dosis pemberian bahan pakan yang mengandung asam siklopropenoat (Phelps et al, 1964). Asam lemak siklopropenoat juga menyebabkan meningkatnya kandungan asam stearat dan menurunnya asam oleat pada beberapa jaringan seperti pada plasma darah, hati, ovari dan jantung hewan darat (Mairizal, 1998).…”

ABSTRAKBiji kapuk memiliki potensi sebagai bahan baku lokal pakan ikan karena ketersediaannya dan mengandung protein dan asam lemak linoleat yang cukup tinggi, namun juga mengandung zat antinutrisi gossypol dan asam siklopropenoat. Oleh karena itu, penelitian ini bertujuan untuk mengevaluasi pemanfaatan tepung biji kapuk ini dalam pakan terhadap kecernaan pakan, gambaran darah, dan kinerja pertumbuhan ikan mas. Hewan uji yang digunakan adalah ikan mas berukuran 5 g, yang dipelihara dalam akuarium kaca berukuran 80 cm x 50 cm x 40 cm dengan kepadatan 20 ekor/akuarium. Perlakuan yang dicobakan adalah pakan uji yang mengandung tepung biji kapuk berbeda yaitu 0%,10%, 20%, 30%, 40%, dan 50% bahan kering. Ikan diberi pakan uji secara satiasi tiga kali sehari selama 60 hari. Hasil penelitian menunjukkan perbedaan kadar tepung biji kapuk dalam pakan memberikan pengaruh berbeda nyata (P<0,05) terhadap pertumbuhan ikan dan pemanfaatan pakan. Laju pertumbuhan harian, efisiensi pakan, retensi protein, dan lemak menurun dengan meningkatnya kandungan tepung biji kapuk dalam pakan. Aktivitas enzim pencernaan dan koefisien kecernaan pakan juga menurun dengan meningkatnya kandungan tepung biji kapuk dalam pakan. Peningkatan tepung biji kapuk dalam pakan meningkatkan kandungan gossypol dalam darah, hati, dan ginjal ikan mas, dan selanjutnya menurunkan kecernaan dan pemanfaatan nutrien pakan bagi pertumbuhan ikan mas. Berdasarkan hasil penelitian dapat disimpulkan bahwa kandungan biji kapuk 7 10% memperlihatkan pertumbuhan terbaik.KATA KUNCI: kecernaan, parameter darah, pertumbuhan, tepung biji kapuk ABSTRACT:Evaluation

“…The malvalic and sterculic acid content of flower bud tissue was about 0.02% -0.10% of the dry weight although the cyclopropenoid fatty acids comprised 5%-8% of the fatty acid content. The cotton seed oil may contain up to 2% of cyclopropenoid fatty acids (Phelps et al, 1964). It therefore seems unlikely that these lipids play a major role in defence against the attack of these insects on the flower bud.…”

“…Raju & Reiser (1967) have demonstrated that methyl sterculate inhibits the stearic acid desaturase system in rats; similar results have been observed in Chlorella (James et al, 1968). There are also reports that the cyclopropenoid fatty acids may act by altering the permeability of cellular membranes (Phelps et al, 1964). The flavonoids, including condensed tannins, have a variety of phenolic groups.…”

Four classes of cotton constituents — condensed tannins, flavonoids, terpene aldehydes and cyclopropenoid fatty acids — were isolated from leaves and parts of squares and fed to Lepidopterous larvae in an artificial diet. The ED50 required for growth inhibition of Heliothis virescens, H. zea and Pectinophora gossypiella larvae ranged from 0.1 per cent to 0.7 per cent of the weight of the diet. The relationship of insect/host plant interactions to where and when cotton allelochemicals occur is discussed. RÉSUMÉ INHIBITION DE LA CROISSANCE LARVAIRE DES LÉPIDOPTÈRES PAR LES CONSTITUANTS DU COTON Quatre catégories de constituants du coton: tanins condensés, flavonoïdes, terpène aldéhydes et acides gras cyclopropénoïdes, ont été isolées à partir de feuilles et de carrés et ont été données à des larves de lépidoptères dans une ration alimentaire artificielle. La DE50 nécessaire pour inhiber la croissance de larves de Heliothis virescens, H. zea et Pectinophora gossypiella allait de 0,1% à 0,7% du poids de la ration. On discute la relation entre les interactions insecte/plante‐hôte et le lieu et le moment où les substances allélochimiques du coton sont présentes.

“…The yolk then remains spherical when separated from the egg and is hard to the touch. Johnson and Shenstone (1964), Phelps et al (1965), Allen et al (1967), and Johnson et al (1967) attributed this change in form and texture to an increase in the ratio of saturated fatty acids (e.g. stearic acid) to unsaturated fatty acids (e.g.…”

SummaryTwo storage disorders, "pink white" and "pasty yolk" are known to develop in eggs from hens with cyclopropene fatty acids (e.g. malvalic and sterculic acid) in their diet. The pink white condition is related to increased diffusion processes in the egg during storage. The pasty yolk condition is related to an increase in the proportion of saturated to unsaturated fatty acids in the yolk. The change in texture becomes evident during storage at normal temperature, but can be induced quickly in any affected egg, even when new-laid, by low temperature. The present investigations were carried out to see if the development of these defects could be related to any structural differences detectable in eggs from hens fed a cyclopropene compound.Eggs from White Leghorn hens, fed 14 mg methyl sterculate/kg body weight/day, were examined, when new-laid and after storage at 0 and 20°0 for periods up to 70 and 50 days respectively, and compared with those from hens fed a . normal diet. The optical and electron microscope observations concentrated on the vitelline membrane and the yolk from these eggs. No marked structural changes were observed in the vitelline membrane to account for the increased diffusion from the albumen and the yolk. This observation supports existing opinion that normal diffusion in the egg is controlled by the physico· chemical organization of the yolk rather than by resolvable structures in the egg. It is likely that these barriers to diffusion are altered when cyclopropene fatty acids are included in the diet. No consistent structural changes which could be related to the occurrence of the pasty condition were observed in the yolk of affected eggs.
