Background: This investigation provides the data of breeding management practices followed by the livestock owners of milkshed and non-milkshed areas and analyze the effect of operation flood program in milkshed area of Bikaner district of Rajasthan in respect to dairy cattle breeding management practices.Methods: In order to achieve the objectives of this study a field survey was conducted. The information required to complete the study were collected from milkshed and non-milkshed villages of Bikaner district. The data was collected by using the pretested interview schedule by visit to their farm to take visual observations and actual measurements of the various desired aspects. The collected data was tabulated and subjected to various statistical methods to draw meaningful inferences. Result: Impact of operation flood programme could most appreciably be seen on the improvement of breeds and breeding methods. Significantly (P less than 0.01) higher percentage of Rathi and crossbreds (41.89% and 13.14%) were found in milkshed area with the low incidence of natural service in comparison to non-milkshed area having low percentage of pure and crossbred cattle with high incidence of natural service. A significantly higher percentage (54.11%) of dairy cattle owners in milkshed area get their cattle inseminated/crossed after 7-12 hours of detection of heat, whereas in non-milkshed area only 32.22% get their cattle inseminated/crossed after 7-12 hours of heat detection. The operation flood program had statistically significant (P less than 0.05) effect on milkshed area with respect to genetic improvement of their stock.

Dairy Cattle Breeding

SUMMARYThe state of the dairy herd in Kenya is described. The organization of the national dairy cattle breeding programme and the sire evaluation methods used are discussed in the light of the available data (1978–1988) and the relevant bibliography It is underlined that it was only possible to keep-up milk production - which matches consumption - by a dairy cattle population growth of 220% in the past decade, while the average yield remained unchanged around 3500 kg milk/lactation. The author underlines the need to improve livestock management practices and the genetic potential of dairy cows as the only means to face the needs of a growing human population.

According to the current “Instruction” used in dairy cattle selection and breeding in the Republic of Kazakhstan, bulls-producers of dairy breeds are assessed according to the their offspring quality based on the principle of “peer daughter”. This means that the phenotypic indicators of the daughters of the tested bulls are compared with the corresponding indicators of their peers. In European countries with developed dairy cattle breeding, as well as in Canada, the USA, etc., to ensure a reliable forecast of the genetic value of individuals (primarily, bulls-producers), use is made of the best linear unbiased forecast method (BLUP method). This method implies that the breeding value of producers is determined by the deviation values of the development of traits of the examined animal from its average values in the population. Especially urgent area is the research aimed at improving breeding programs, including assessing the breeding value of bulls-producers of dairy breeds using BLUP methods based on the productive qualities of the mass of dairy cattle in the Republic of Kazakhstan. The research material included the data on the phenotypic indicators of the milk productivity of first-calf cows (the amount of milk yield, the content of fat and protein in milk, the yield of milk fat and protein) of the Holstein black-motley dairy cattle breed, obtained from the information and analytical database of the Republic of Kazakhstan for 2016–2017. It was found that when evaluating according to the official “Instruction”, 16 sires out of 256 bulls (6.2%) got the stud category in 2016, 14 sires (9.2%) out of 152 bulls in 2017, and – 30 sires of 249 bulls (12.0%) over the cumulative period. The results of the conducted research prove that the use of the classic “Instructions” in dairy cattle breeding has lower efficiency (by 42.8–90.0%) as compared with the assessment of the breeding value of bulls based on the BLUP method.The selection of sire bulls into breeding groups based on the “peer daughter” methodology is not reliable enough and rather ineffective. Comparing the results of assessing the breeding qualities of sire bulls, obtianed using two methods in all compared periods (2016, 2017, 2016–2017), the authors established a clear superiority of the BLUP method over the current Instruction used in the Republic of Kazakhstan.
