Abstract Goat meat is consumed all over the world because of its nutritional profile and delicacy. It produced in areas Pakistan but Karakoram region mostly organic animals are fed on natural vegetation having nutrition benefits for humans. In current study, goats were reared different systems flora alfalfa grass hey (MS I) sea buckthorn II), Russian Olive III) mix ration olive IV). The 6 month...

background: vitrification has proven to be more effective than slow freezing methods to cryopreserve mammalian oocytes. the objectives of this study were to evaluate the effects of vitrification on immature and in vitro matured, denuded and cumulus compact goat oocytes and their subsequent fertilization. methods: oocytes were either cryopreserved as immature cumulus compact (imcc) (n=98 exp 1; ...

the present study was carried out to investigate the effect of different seasons on length and duration of estrus as well as to observe the behavioral changes and physiological peculiarities during estrus period. three climatic seasons and age groups were considered: summer (march-june), rainy (july-october) and winter (november-february); a (6-9 month), b (9-12 month) and c (>12 month). estrus...

A novel integrated buck-flyback non isolated power factor (PF) correction (PFC) converter is proposed in this paper. This new converter is an inherent integration of a buck converter and a flyback converter, which operates in either flyback mode or buck mode according to whether the input voltage is lower or higher than the output voltage. In this way, the dead zones of ac input current in trad...

Controlling of DC-DC converter is vital task in power conversion. DC-DC converters are used in many applications like solar charger, computer power supplies, switching mode regulators, aircrafts etc. Focus of this paper is to model a controlling system for buck converter which controls output of buck converter constant instead of changing load and input supply to buck converter. Controlling met...

Cdv/dt induced turn-on of the synchronous MOSFET deteriorates performance in synchronous buck regulators. We will discuss this problem and provide several solutions that can reduce the effects. SYNCHRONOUS BUCK REGULATOR Synchronous buck topology is becoming popular in powering ultra-fast CPU cores. A standard buck circuit is shown in Figure 1(a) and a synchronous buck is shown in Figure 1(b). ...

This paper presents, linear peak current mode controller for the control of DC/DC buck converter is designed and analyzed. Dynamic equations describing the buck converter are derived and linear peak current mode controller is designed. The buck converter, the voltage mode and current mode controller are modeled and are evaluated by computer simulations. The proposed technique has the advantages...

Background: Pantja is a medium sized, dual purpose Tarai goat breed of Uttarakhand and adjacent area Uttar Pradesh. Due to the lack pure breeding buck uncontrolled cross breeding, population this reducing continuously. Therefore, for preservation dissemination breed, cryopreservation semen artificial insemination by using frozen thawed can play crucial role. Methods: Semen samples were collecte...
