Effects Of Papaya Leaves In Combination With Medicinal Herbs And Probiotic As Functional Feed Additives On Growth Performances And Health Of Hybrid Tilapia (Oreochromis niloticus × O. mossambicus)
(2025-08)
Onas, Somdare Peace
The present investigation was conducted to evaluate the effect of papaya leaves in combination with medicinal herbs and probiotic as functional feed additives on growth performances, activities of digestive enzymes, intestinal morphology, and haemato-biochemical parameters of hybrid tilapia.
Pemilihan Dan Pembiakan Asparagus (Asparagus Officinalis L.) Var. Mary Washington Melalui Kaedah Kultur Tisu
(1997-04)
Othman, Mohamad Suhaimi
Seks tanaman asparagus tidak dapat ditentukan melalui morfologi biji benih. Biji benih yang berlainan saiz mengeluarkan satu atau lebih tiler tetapi ini tidak menunjukkan potensi pengeluaran hasil yang sebenar. Oleh yang demikian ciri-ciri pemilihan klon yang unggul tidak bergantung kepada saiz atau bilangan tiler yang dikeluarkan oleh biji benih. Walaubagaimanapun setiap biji benih mempunyai potensi pengeluaran hasil yang berbeza antara satu sama lain. Oleh itu pemilihan berdasarkan setiap biji benih perlu dilakukan.
Kelakuan Makan Semut 'Pharaoh', Monomorium Pharaonis (L.) (Hymenoptera : Formicidae) : Pengrekrutan, Pemilihan Dan Pengagihan Makanan
(1997-06)
Chong, Shu Chien @ Alexander
Kajian ini telah bertumpu kepada beberapa aspek perlakuan pemakanan semut 'pharaoh', monomoriuni pharaonis (l.), iaitu pengrekrut.An massa, pemilihan makanan dan pengagihan makanan antara ahli koloni. Semasa pengrekrutan, pekerja semut 'pharaoh' berperanan sebagai pengakap kembali ke sarang dan menarik pekerja ke sumber makanan yang baru dijumpai. Keputusan eksperimen menunjukkan bahawa proses pengrekrutan. Pekerja adalah proses dinamik yang boleh berubah mengikut keadaan seperti kualiti (kekayaan) umpan dan juga tahap kelaparan koloni. Dalam kehadiran umpan berkualiti tinggi, lebih banyak pekerja direkrut untuk memakan berbanding dengan umpan kurang berkualiti. Pengrekrutan adalah tertinggi apabila koloni mengalami kelaparan yang lama diberikan umpan paling berkualiti.
Analysis Of Microbial Community Diversity In The Regurgitated Pellets Of Barn Owls (Tyto Javanica Javanica)
(2025-08)
Ahmad Kamal, Mohd Hasif
The diversity of microbe associated with captive and wild tropical barn owl is indeed diverse in general. Given that owls can harbour both beneficial and harmful microbes, understanding their microbial diversity is crucial for identifying the potential of infectious diseases spreading either to human, plants and crops. The aim of this study is to determine the diversity and abundance of microbial communities associated with captive and wild barn owls, investigate the effects of dietary components and geographical locations of the owl on these microbial populations, and discover key microbial species through the owl. All fresh regurgitated pellets were retrieved from each owl from their own site which are Aviari USM, Bumbung Lima and Jengka.
Pheromones Of Fruit Flies (Bactrocera Spp.) And The Glandular Anatomy Of Wild Orchids (Bulbophyllum Spp.) That Attract The Fruit Flies.
(1996-11)
Nallakumar, Krishnakumari Anm.
The rectal gland secretions of males of Bactrocera dorsalis, Bactrocera papayae, Bactrocera carambo/ae and Bactrocera umbrosa that were fed 'Mth methyl eugenol and eugenol were isolated and identified. Through this work methyl eugenol has been established as a more potent and effident attractant compared to eugenol. The major glandular components that occur naturally in these spedes are long chain saturated and unsaturated fatty acids, spiroacetals, ketols, esters and amides. Two phenylpropanoids, 2-allyI-4,5-dimethoxyphenol (Compound Z) and 4-(3-hydroxy- 1-propenyl}-2-methoxyphenol or coniferyl alcohol, and one amide, N-3-methylbutyl acetamide were identified as the major glandular components of all four Bectrocet» species in this study when they were treated Vvith methyl eugenol. A compound, 6-oxo-1-nonanol, was identified only in the rectal secretions of Bactrocera carambolae and it was found to be the major component in the rectal glands of sexually mature males, and thus it is characterised as a naturally occuring pheromone in Bactrocera carambolae. A phenylpropanoid, cis 3,4- dimethoxycinnamyl alcohol, was also identified in the rectal secretions of B. dorsalis and B.umbrosa. Only 2-allyl-4,5-dimethoxyphenol was detected in the rectal glands of males of B. papayae that were fed 'Mth eugenol. None of the other three species in this study produced any form of pheromones when fed wth eugenol, except for the increase in the naturally occuring pheromone in B.carambolae. In other words, both methyl eugenol and eugenol take on the role of precursor in the manufacture and production of pheromones in the male rectal glands of all four species. A detailed study on the
