    Studies on the preservation of boar semen in various extenders
    (Department of Animal Reproduction, College of Veterinary and Animal Sciences,Mannuthy, 1977) Vijaya Kumaran, KAU; Neelakanta, Iyer C P
    With the ultimate object of evolving a suitable extender for boar semen 72 ejaculates from six boars selected at random from University Pig Breeding Farm, Mannuthy were used for the preservation studies. Six diluents viz., Egg yolk – glucose – citrate, 111ini variable temperature diluent, Coconut milk extender, Kiew – 1, Kiew – 11 and Glucose – glycine – EDTA – bicarbonate – citrate diluent were used to study the keeping quality of boar semen at two temperatures of storage ( 150 and 50C). The highest percentage of progressively motile sperms was observed in glucose – clycine – EDTA – bicarbonate – citrate, Kiew – 11 and Kiew – 1 extenders. At 150 C semen could be stored in these extenders upto 60 hours with good motility. Coconut milk extender proved to be least suitable for the preservation of boar semen both at 150 and 50 C of storage. Progressive motility in all the diluents was higher at 150 C than at 50 C.

    Development of a low cost garden tractor
    (Department of Agricultural Engineering, College of Horticulture, Vellanikkara, 1982) Sivaswami, M; KAU; Muhammad, C P
    The study was conducted with the objectives of systematic analysis of components with respect to their kinematics, dynamics and ergonomics and evaluation of traction performance and economics of low cost garden tractor. A greaves Lombardini 5.4 hp diesel engine with 1800 rpm was selected and a simple three step speed reduction system having a single stage V belt drive and double stage chain drives with a pivotted countershaft clutch have been designed. A road speed of 6.635 kmph and field speed of 3.317 kpmh were achieved by using a cone pulley arrangement with 6.00 x 12 size wheel.Correct position of various components bringe the centre of gravity of the unit with and without implement at very close to the final drive axle for easy balancing

    Development of small scale equipment for extraction of cocoa butter and production of cocoa powder
    (Department of Agricultural Engineering, College of Horticulture, Vellanikkara, 1982) Ganeshan, V; KAU; George, T P
    The primary objective of this project was to evolve a viable technology and equipment system for small scale processing of cocoa beans. The study mainly concentrated on the development of an extraction unit for the separation of butter from cocoa mass. Various equipment required for small scale processing of cocoa beans were either identified or designed.
