Problem Identification
Genetic improvement programs at the animal (e.g. dairy cattle production) level are a well-understood process aimed at generating favorable genetic change in the animals. We must been in correct on usually with the aim of improving profit may be it’s not difficulties if we are understand the current development of the estimation genetic parameters. In simple terms this process consists of three key decisions are as: what does breed for (breeding objectives), which animals to breed from (evaluation and selection), and how to mate the selected individuals (mating programs). What, if anything, changes as we adopt one step to recovering "Review Estimation" perspective, and hence what is meant by the terms "Genetic Parameters Calving Difficulty and Birth Weight for first and later parities especially Friesian Holstein"?
Clearly, the simple describes of the major differences between estimation genetic parameter that is evaluation calving difficulty and birth weight perspective and that of Friesian Holstein for first and later parities are:
· Calving difficulty or in another word “dystocia”. That is trend the majority of selection emphasis in dairy breeding is placed on production and reproduction traits. Meaning selection emphasis is we must been focus in selected the reproduction traits not only of production traits. Both traits reproductive are important in maximizing longevity and reducing losses due to mortality and after stillbirth. Without care and focus of reproduction traits will carrying trouble these on birth density, total populations and operational costs (e.g. labor and veterinary costs).
· Definition due to both traits that is the truth of complete chains to perspective will consider many decision-makers and the entire breeder-to-reproduction traits of chains.
· Higher calving difficulty will trend higher losses cost to assistance on birth, cause higher birth weight. In the meantime, we must look at extra to assistance of dairy cattle the majority these on time when an animal will be birth.
For that is we need to review again what can we do to assistance and being avoid repeatedly calving difficulty and than increased to stillbirth. May be not only calf but mother can do it. The difficulty on stillbirth level not always can changes and bias to theoretical. The solution can do that is the management exactly. The concentration of management should be became importance to repaired genetic parameters (e.g. calving difficulty, birth weight, etc.) and than we’ll find a method to improvement an animal reproductive traits. The exactly of management (e.g. breeding management, feeding management, or general management), we’ll make ourselves relax of reproductive cases. Wherever and whoever reproductive cases in an animal herd don’t ever has a bad feeling and than we’ll under pressure of reproductive cases.
