Abstract:

Problem. On the present time both Lithuania and EU market dominate pigs and cattle breeding. Consumer researches shows, that growing demand on high digestibility and nutrient, quick prepare animal products. On this way duck meat is very valuable product. Problem is that now dominate small farms, where traditionally growing few local, not very productive ducks. Like there is no real local market, so there is no well develop duck breeding. The subject of research. After good analyses of duck breeding and risk factors, to take measures of duck business development in Lithuania. Tasks: To estima

Abstract:

Nest predation is a major factor impacting duck production and recruitment on breeding areas in North America. I surveyed waterfowl managers employed by the U.S. Fish and Wildlife Service and U.S. state wildlife agencies to determine their beliefs about nest predation and its management. Over 64% of respondents believed that rates of nest success on their management units averaged <30% between 1996-2000. Managers believed habitat management and direct predator control were the most effective techniques to reduce nest predation. The construction of predator exclosures around nesting habitat als

Companies are constantly expected to be more competitive while working in an environment in which time and cost are limited, thereby preventing such companies from taking the time required to be responsive. It is, therefore, important that companies understand that conventional knowledge and methods will not serve unless there is a concerted focus on improvement of organisational performance toward fulfilling increased expectations, not just maintaining that which is comfortable. A more sustainable approach may be the introduction of lean manufacturing techniques. The lean manufacturing proces
