Abstract:
Dairy cattle brucellosis is a chronic bacterial disease, which is caused by Brucella abortus and mainly characterized by abortion in dairy cattle. With the rapid development of breeding industry of milk cows in China, the infectious cases of dairy cattle brucellosis show an increasing trend. Particularly in Jilin province, the annual number of the positive cases of dairy cattle was only 3 cows in 1987, and went up to 168 cows in 2005. Based on the situation of the brucellosis infection in Jilin province, we propose an Susceptible-Exposed-Infected-Virus (SEIV) dynamical model with outside trans

AbstractThe paper presents the impact of the applied technologies on milk yield of cows in dairy farms. The scope of the research covered technical equipment used in the dairy cattle breeding and milking in 50 farms on the area of Grajewo Province in Podlaskie Voivodeship. The studies were carried out in 2016 with the diagnostic survey method based on the interview questionnaire developed for this purpose. The studies proved that 68% of the respondents from Grajewo Province maintain cattle in a stanchion-tide stable system and the remaining 32% in a free stall system. The group (48%) of the su

Abstract:
The paper presents data on the cattle industry in the People's Republic of China and the Republic of Serbia. China is the third largest dairy producing country and the third largest beef producing country in the world. In 2011, the dairy cow population in China was 14.4 million. Chinese dairy breed is mainly obtained by grading hybridization from Holstein, Simmental, etc. which were introduced from foreign countries, and local cattle breeds for long time to form the offspring with stable genetic characteristics. Currently, the dairy breeds cultured in China mainly include Chinese Holstein, Chi

Background. The primary specialization branches of agriculture in Tyumen Province are plant production and dairy farming, with cattle husbandry being lately introduced, which implies a demand for feed crops, in particular perennial grasses, among which smooth brome (Bromopsis inermis (Leyss.) Holub) is the most widespread. With such demand in mind, the Research Institute of Agriculture for the Northern Trans-Urals has been engaged in studying pasture grasses in order to find and develop new lines adaptable to local conditions.

Abstract:
This study has compared the effect of milk pricing systems on the selection goals of dairy producers in two provinces of Canada, British Columbia (BC), and Quebec. These provinces were chosen for comparison as BC produces milk largely for a fluid market, while Quebec produces milk for a manufacturing market. Within BC, due to a higher utilization and higher milk price, the value/kg of skim on Vancouver Island was higher than that of the Vancouver Lower Mainland over the study period 1963-1982. Between the two provinces, the value/kg of skim in BC was found to be consistently higher than in Que

Abstract:
The objective of the study was to evaluate cow reproductive performance in the sweetveld and sourveld communal grazing areas of the Eastern Cape Province, South Africa. In the first experiment, farmer perceptions were obtained using participatory rural appraisals. Farmers ranked lack of fences, tick-borne diseases, poor animal condition during winter and poor breeding practices, respectively as major constraints limiting cattle production in the Eastern Cape. Cattle, sheep and goats, in that order, were ranked as the most important livestock species and were mainly kept for meat, cash and cere
