Sustaining Aquaculture Development : The Feeds and Feeding Connection
No full textAquaculture has traditionally played a role in ensuring food security for humans and is often a component of rural development programmes to alleviate poverty. In the last three decades, the aquaculture industry has grown at an unprecedented rate stimulated by the increased demand for fish and fishery products as global population awareness of fish as a health food increased and the almost static production from capture fisheries. Indeed, aquaculture has expanded to become the fastest food producing industry in the world and is expected to contribute to more than half of the global fish consumption by 2030 (FAO, 2000)
The Use of Live, Frozen and Pottasium Permanganate Treated Moina micrura for Catfish (Clarias macrocephalus) Larvae
No full textLive, frozen and pottasium permanganate (KMnO4) treated Moina micrura were fed to catfish (Clarias
macrocephalus) larvae for 20 days. The aim of KMnO4 treatment prior to feeding was to minimise the level of
microorganisms present in them. micrura culture. The growth rates and feed conversion ratios for the live untreated
and KMn04 treated M. micrura were not significantly different. Frozen M. micrura had a significantly lower
growth rate and significantly higher feed conversion compared with the live, untreated M. micrura. The results on
relative growth and feed conversion of fry fed the treated and untreated suggest that M. micrura retained its nutritive
qualities even when treated with 1µM KMn04 and is suitable as a larval feed

No full textSupplementing Artificial Diets for Catfish (Glarias macrocephalus)Fry with Tubifex
No full textThree-week-old catfish (Clarias macrocephalus) fry were fed experimental diets at protein levels of 30% and
35% fish meal dominant and 35% and 40% soybean dominant types for 8 weeks. Nine treatments were tested
with four treatment consisting wholly of experimental diets, one ofTubifex (control) and the remaining four diets
supplemented with live Tubifex. Fish reared on experimental diets supplemented with live Tubifex fed more
actively and showed better growth and feed efficiency than those reared without supplemented diets. Those on the
30% and 35% fish meal dominant feed showed significantly better growth and feed conversion than those fed
35% 40% soybean dominant diet

No full textA study was carried out to determine a procedure for producing high yield of bioactive flavonoids from Mimosa pigra as antioxidant. Various parts of Mimosa pigra were extracted using various solvents such as methanol, 80%
methanol, ethanol, 70% ethanol and ethyl acetate in two ways: (1) eluted in the solvents overnight; (2) boiled the Mimosa pigra in the solvents for l-2 hours and
left it overnight
A Comparative Study on Physicochemical Characteristics of Raw Goat Milk Collected from Different Farms in Malaysia
No full textThis study was conducted to determine the physical and chemical composition of goat milk produced by eight local farms located in the central region of Malaysia. Farms 1 to 4 (F1-SC, F2-SP, F3-SP, F4-SBC) reared Saanen-type goats while farms 5 to 8 (F5-JK, F6-JPEC, F7-JTC, F8-JC), Jamnapari-type goats. The common feedstuffs used in all farms comprised of fresh or silage from Napier grass, feed pellets, and brans while two farms, F5-JK and F6-JPEC supplemented the feeds with soybean-based product. The total solid content, dry matter, and proximate composition of goat milk and feedstuffs from the different farms were determined and the results analysed using principal component analysis. Total solid content of goat milk from the Jamnapari crossbreed had the highest solid content ranging from 11.81% to 17.54% compared to milk from farms with Saanen and Saanen crossbreed (10.95% to 14.63%). Jamnapari-type goats from F5-JK, F6-JPEC, and F8-JC had significantly higher (p < 0.05) milk fat and protein contents (7.36%, 7.14%, and 6.59% fat; 5.08%, 6.19%, and 4.23% protein, respectively) than milk from other farms but, milk produced by Saanen-type goats from F4-SBC contained similar protein content (4.34%) to that from F8-JC. Total ash and carbohydrate contents in milk ranged between 0.67% to 0.86% and 3.26% to 4.71%, respectively, regardless of goat breed. Feeding soybean-based products appear to have a positive influence on milk fat and protein content in Jamnapari type goats.
Kajian ini dijalankan untuk menentukan komposisi fizikal dan kimia susu kambing yang dihasilkan oleh lapan ladang tempatan yang terletak di kawasan tengah Malaysia. Ladang 1 hingga 4 (F1-SC, F2-SP, F3-SP, F4-SBC) menternak kambing jenis Saanen sementara ladang 5 hingga 8 (F5-JK, F6-JPEC, F7-JTC, F8-JC) menternak kambing jenis Jamnapari. Bahan makanan biasa yang digunakan di semua ladang terdiri daripada rumput segar atau silaj dari rumput Napier, feed pellets, dan bran sementara dua ladang lagi, F5-JK dan F6-JPEC menambah makanan dengan produk berasaskan kacang soya. Kandungan pepejal, bahan kering dan komposisi susu kambing serta bahan makanan dari lading yang berbeza telah ditentukan dan keputusan dianalisis dengan menggunakan analisis komponen utama. Kandungan pepejal susu kambing dari kacukan Jamnapari mempunyai kandungan pepejal tertinggi iaitu 11.81% hingga 17.54% berbanding susu dari lading dengan Saanen dan kacukan Saanen (10.95% hingga 14.63%). Kambing jenis Jamnapari dari F5-JK, F6-JPEC, dan F8-JC mempunyai kandungan lemak dan protein susu (p < 0.05) yang lebih tinggi (7.36%, 7.14% dan 6.59% protein; 5.08%, 6.19% dan 4.23%) daripada susu dari ladang lain tetapi susu yang dihasilkan oleh kambing jenis Saanen dari F4-SBC mengandungi kandungan protein yang sama (4.34%) dengan F8-JC. Kandungan abu dan karbohidrat dalam susu adalah di antara 0.67% hingga 0.86% dan 3.26% hingga 4.71%, tanpa mengira baka kambing. Memberi makan produk berasaskan kacang soya dilihat mempunyai pengaruh positif terhadap kandungan lemak susu dan protein dalam kambing jenis Jamnapari
EFFECTIVENESS OF THE FERMENTATIVE EXTRACT OF Lactobacillus acidophilus AS ANTIMICROBIALS AGAINST Aeromonas hydrophila
No full textThe purpose of this study was to evaluate the in vitro and in vivo antimicrobial activity of the commercial Lactobacillus acidophilus (L. acidophilus) cells and cell free extract against Aeromonas hydrophila (A. hydrophila). The in vitro method was carried out using well diffusion method. For in vivo evaluation, the effect of L. acidophilus on the survival rate of Pangasianodon hypophthalmus (P. hypophthalmus) infected with A. hydrophila was evaluated. The well diffusion method showed a significant inhibition ability of L. acidophilus cells against A. hydrophila compared to the cell free extract. The inhibition diameters obtained with cells and cell free extract were 17.23 mm and 15.17 mm, respectively. P. hypophthalmus injected with L. acidophilus cells and cell free extract following challenged with A. hydrophila cells showed survival rate of 70% and 60% respectively, at 2-week post challenged. The gas chromatography-mass spectrophotometry (GC-MS) result revealed that a diverse of compounds was detected in both the L. acidophilus cells and cell free extract, among them the most abundant component was pyrrolo[1,2-a]pyrazine-1,4-dione, hexahydro-3-(2-methylpropyl), which showed a promising anticancerous activity and might be played a significant role in the recovery of the infectious P. hypophthalmus. The current study revealed that both cells and cell free extract of L. acidophilus have antimicrobial activity against A. hydrophila

No full textEffect of dietary prebiotics and probiotics on snakehead (Channa striata) health : Haematology and disease resistance parameters against Aeromonas hydrophila
No full textThis study examined the effect of dietary prebiotics and probiotics after 16 weeks, followed by 8 weeks of post feeding trial with the control unsupplemented diet on haematological and immune response against Aeromonas hydrophila infection in Channa striata fingerlings. Fish were raised on a 40% protein and 12% lipid feed containing three commercial prebiotics (β-glucan, GOS or galacto-oligosaccharide, MOS or mannan-oligosaccharide); and two probiotics- (Saccharomyces cerevisiae, Lactobacillus acidophilus), respectively and a control. Throughout the study, supplementation with dietary prebiotics and probiotics led to significant (P < 0.05) improvement in the red blood cells, white blood cells, packed cell volume, haemoglobin concentration and serum protein level and lysozyme activities; and these improvements were effective significantly (P < 0.05) when the fish were challenged with Aeromonas hydrophila at the dose of 2×106. The disease resistance against A. hydrophila was higher significantly (P < 0.05) in fish fed with probiotic feed supplements (L.acidophilus was highest) compared to prebiotics and control. The study is the first to report the absence of differences in sustaining the efficacies attained afterintakeofβ-glucan, GOSandMOSuponpost-feeding withanunsupplemented feed, over a prolonged period
