Title

Variation in Milk Yield Of Dairy Cattle: Evaluation on Correction Factors of Internal Environmental Effects Anggraeni, Anneke
Indonesian Bulletin of Animal and Veterinary Sciences Vol 9, No 2 (1999)
Publisher : Indonesian Animal Sciences Society

Correction factors as standard factor are needed to standardize internal environmental effects to evaluate genetic for desired traits of each breed, strain, or individual animal. Some dairy cattle scientists in warm (cold) and hot climate have made observing correction factors (CF) of internal environmental effects mainly for stages (days length) of lactation, calving age, milking ftequency, days open, and dry period for milk and its components (protein and fat). The correction factors should be done due to high variability onÂ those parameters that occur natually eventhough dairy management have been kept well. Developing correction factors of calving age, days open, and days dry for milk production becomes main discussion in this paper. In Indonesia, correction factors of internal environmental effect for local Fries Holland dairy cattle need to be developed. The appropriate correction factors will be effective to eliminate the variation of milk yield caused by non-genetic effects. So the result of evaluation and selection could be expected to figure out genetic potencial of dairy cattle in producing milk. Â Key words: Milk yield, correction factors, and internal environment

The Role of Dairy Cattle Husbandry in Supporting The Development of National Dairy Industry Anggraeni, Anneke; Iskandar, Sofjan
Indonesian Bulletin of Animal and Veterinary Sciences Vol 18, No 2 (2008)
Publisher : Indonesian Animal Sciences Society

An intensive development in Indonesian dairy industry has expanded over two decades. During this period, the structure of the national dairy industry has progressed completely. The capacity of the national fresh milk production, however, has been able to supply only 35% of domestic milk demand. The milk domestic demand is predicted to be continous due to the increases in the national population and their welfare. Raising temperate dairy breed (Holstein-Friesian) under tropical climate has resulted many deteriorates in productivity. More inferiority has been found under a semi-intensive management at small dairy farms. The existence of various changes in the global trade regulation for agriculture commodities has been a considerable factor directly affecting the future development of the national dairy industry. Increasing efficiency of various determinant components of the national dairy industry is required to produce domestic fresh milk in a good quality at a competitive price. This paper is dealing with the status of various determined factors especially for dairy livestock components to improve the future national dairy industry prospectively, involving for the national dairy cattle population, domestic milk yield, productivity of dairy cattle, breeding system and supporting reproduction technology. More over, other essential factors providing for dairy institution as well as distribution and marketing domestic milk production are also described. Â Key words: Dairy cattle husbandry, small dairy farms, national dairy industry

Genetic Improvement of Milk Quantity and Milk Quality in Holstein Friesian Cattle by Selection Anggraeni, Anneke
Indonesian Bulletin of Animal and Veterinary Sciences Vol 22, No 1 (2012)
Publisher : Indonesian Animal Sciences Society

Milk yield and milk quality are essential in determining the development of national dairy industry. Domestic fresh milk is largely produced by Holstein Friesian Â cows. There is a wide variation of the genetic ability of cows to produce milk or bulls to transmit milk, thus giving the opportunity for the improvement of milk production trait through selection. Milk yield as one of the quantitative traits, in the genetic evaluation, is estimated based on a breeding value. Breeding value can be estimated accurately through appropriate selection methods and by considering various non-genetic factors influencing milk production. This paper focuses the discussion on milk selection methods, which are very commonly done in dairy cattle. To produce superior dairy breeding cattle, selection for the bulls were done by progeny testing method, whereas selection for cows were commonly by individual selection method and their siblings. A number of internal environment factors should be considered in the genetic evaluation of milk production, through the development of appropiate correction factors, thereby increasing the accuracy of the estimated breeding values. The quality of milk especially milk protein contents, in the future, will get more attention from consumers. Therefore, selection should be directed also to improve milk protein components. The existence of major genes controlling on milk protein contents is expected to be the effective way in increasing milk protein yield in domestic HF cow. Selection of superior breeding dairy cattle in producing high milk protein contents is done through the identification of polymorphism of milk protein genes, providing casein and whey family genes. Key words: Holstein Friesian, selection, milk yield, milk protein
