Feeding large-breed puppies.
Growth is a physiologically demanding process that requires adequate amounts of energy as well as optimal intake of essential nutrients. Key nutritional factors, including energy and calcium, have been identified as important during growth. Large-breed puppies have a genetic tendency toward fast growth rates that can stress developing skeletal structures and result in malformations if left unch...

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Effects of amino acids on egg number and egg mass of brown (heavy breed) and white (light breed) laying hens.
Different types (light to heavy) of laying hens are used in practice. There are questions about the optimum level of balanced protein (BP) supply in feed for different types of hens. Therefore, a broad range of amino acids intake levels [550 to 800 mg of true fecal digestible (TFD) Lys/hen per d] was tested on heavy (Lohmann Brown Classic) and light (Lohmann LSL Classic) laying hens from 24 to ...
متن کاملLife-cycle Feeding Programs for Egg Production
Feeding management of egg laying strains involves both feed formulation. and feeding strategy. Life-cycle programs should be developed at day-of-age and be geared to desired production goals in the layer barn. Manipulation of juvenile growth can be accomplished in relation to these goals, the main parameters being mature body weight and age at sexual maturity. Growth of the immature pullet, esp...
متن کاملChemical Composition and the Feeding Value of Azolla (Azolla pinnata) Meal for Egg-Type Chicks
Biochemical and nutritional studies were carried out to evaluate the potential of Azolla (Azolla pinnata R. Brown) meal, AZM, as a feed resource in the diet of egg-type chicks. In a completely randomized design, 30 two weeks old Nera brown chicks were assigned to each of the four dietary treatments containing 0, 5, 10 and 15% azolla meal. Chemical analysis indicated that azolla meal contained (...
