Abstract:

Milk production is one of the most important areas of the Czech agrarian sector, as evidenced by its 50% share (at 2017 prices) in revenues from livestock production. As for any business, a certain level of profitability is a prerequisite for long-term and sustainable development of dairy farms. This study’s aim was to evaluate the economic efficiency of milk production from both Czech Fleckvieh (C) and Holstein (H) cows based on data collected each year from 48 to 70 Czech dairy farms in the period from 2012 to 2017. Total costs per feeding day and litre of milk, level of profitability, and i

Abstract:

Relations between the level of milk yield and the economic results of dairy cows breeding were analysed on the base of operational and economic data received from 135 agricultural enterprises. The analysis was aiming at the optimization of milk production expressed by means of the cost function. By evaluating the above-mentioned relations, there was recorded a tendency of the faster growth of milk yield compared to the costs for market milk for one feeding day of a dairy cow. On the base of the expense function, there was expressed the maximum profit for a litre of market milk, the maximum pro

Abstract:

Costs are an important economic category that have a decisive influence on the definition of pricing policies and the formation of financial performance of the enterprise, characterizing the level of organization of production and application of technologies. According to expediency of their spending, costs are divided into productive and unproductive. Unproductive costs arise in the event of a violation of technology, deficiencies in the organization of production, etc. Therefore, it is necessary to ensure that the economic evaluation of unproductive costs in breeding dairy cattle is carried

The economic viability of dairy farms is a measure of their ability to survive and grow. Its measurement is particularly important in periods of changes taking place in the environment of these entities. The last decade of the European dairy market was characterized by significant changes in regulations, which resulted in fluctuations in farm gate milk prices and, consequently, impacts on farm income. The main objective of the research was to assess the economic viability of dairy farms located in the European Union. The research area covered the countries that have the most raw cows’ milk del

ABSTRACTThe generation of profit in dairy production can be approximated by a generalized profit equation, which is a function of the genotype of the animals used. In the absence of legislated quotas on production, the economic weights for traits contributing to profit, for use in a selection index, have been shown to be simple functions of the partial derivatives of profit with respect to output of the traits. These functions reflect the fact that output in most agricultural industries will already be maximized, either because of saturated markets or limitations on total inputs. When a single

Abstract:

The amount of milk Canadian dairy farmers produce is limited to a production quota expressed in milk fat. Because milk economic value is primarily based on fat and protein, it can be advantageous to decrease the milk fat to protein ratio. Monensin sodium has been suggested to reduce milk fat proportion and outputs, but not milk protein. Publications using lactating dairy cows were utilized to assess predictability of production responses to monensin feeding based upon their base production characteristics and diet composition.

Abstract:

Recently, due to the widespread implementation of intensive milk production technologies, the requirements for the type of animal physique have increased, because the theory and practice of breeding have proved that the economic and long-term use of cows is not possible without taking into account their exterior features and type of the constitution. The influence of the traits of the animals’ physique on the duration of their economic use was studied, and the main slaughter grades and standards minimum percentage of cows determined beaf cow culling were determined.

Abstract:

Recently, an important element in improving the genetic traits of dairy cattle on commercial farms is the use of interbreeding (crossbreeding). The use of crossbreeding makes it possible to use a variety of additive genetic levels between breeds to grow individuals with higher economic potential. The aim of this study was to analyze the development of udder parameters in crossbred first-borns compared to purebred counterparts and to study the indicators of milk production during milking. The research was conducted on the first-born Ukrainian black-spotted dairy breed and first-generation cross

Ketosis is a cattle illness caused by the lack of energy and can be mostly found around peak lactation. Ketosis causes economic losses due to decreased milk production, impaired fertility and increased risk of displaced abomasums. Ketosis is classified clinically and sub-clinically. Sub-clinical ketosis is more deleterious than clinical ketosis. Ketosis is clinically diagnosed if the milk acetone level in milk sample is more than 50 mg/L. When the acetone level in milk is between 25 - 50 mg/L or the blood beta-hydroxybutyrate (BHBA) is over 1200 micromol/L ketosis status is sub-clinical. Howev

Abstract:

The aim of this review was to summarize new genetic approaches and techniques in the breeding of cattle, pigs, sheep and horses. Often production and reproductive traits are treated separately in genetic evaluations, but advantages may accrue to their joint evaluation. A good example is the system in pig breeding. Simplified breeding objectives are generally no longer appropriate and consequently becoming increasingly complex. The goal of selection for improved animal performance is to increase the profit of the production system; therefore, economic selection indices are now used in most live

This study aimed to evaluate the effect of corn silage (CS) replacement by cassava's foliage silage (CFS) on the production and quality of milk. Twelve lactating dairy cows were used in a randomized block experimental design with four treatments and three repetitions per block. CS was replaced by CFS at the levels of 0, 20, 40, and 60%. The replacement of CS by different levels of CFS had very low effect on the variables studied. Milk density decreased when the replacement level was increased. Fatty acids 4:0 and 6:0 presented a quadratic behavior, while fat acids 8:0, 10:0, and 15:0 presented

Abstract:

Purchased concentrates are a significant variable cost of a dairy business. Farm economic theory states that feeding supplements will enable a dairy farmer to improve profit as long as the marginal revenue received from the milk produced exceeds the marginal cost of the supplement. To do this, the quantities of milk, milk protein and milk fat produced from a unit of concentrate added to the diet are needed. Recent research has compiled results from short-term concentrate feeding experiments conducted in Victoria over a 30-year period. Using these data, relationships for the response of milk pr

Selection response from a two-tier nucleus breeding scheme using the current Kenyan breeding goal was compared with an alternative that also accounts for protein yield (PY) and mastitis resistance (MR). The economic value for PY was estimated using a bio-economic model. For mastitis resistance, like other disease resistance traits, the economic value cannot be estimated with profit equations because they have multi-fold effects on input and output, which affects profitability. Therefore, selection index methodology was used. Somatic cell count (SCC) was used as an indicator trait for MR. The Z

Abstract:

Feed is the largest variable cost for dairy farms in Australia, and dairy farmers are faced with the challenge of profitably feeding their cows in situations where there is significant variation in input costs and milk price. In theory, the addition of 5.2 MJ of metabolisable energy to a lactating cow’s diet should be capable of supporting an increase in milk production of one litre of milk of 4.0% fat, 3.2% protein and 4.9% lactose. However, this is almost never seen in practice, due to competition for energy from other processes (e.g., body tissue gain), forage substitution, associative effe

Abstract:

This analysis presents the development of the Holstein dairy system in Brazil, evaluating system sustainability during a time of crisis, based on changes in system productivity, stability, resilience and equity. Sustainability indicators are used to describe these changes. Records of Holstein cows registered in the National Dairy Cattle Archive from 1980 to 1992 were analysed to include a crisis period around 1990. The Holstein dairy farming system showed high stability and resilience in terms of milk production, although a high sensitivity to disturbances was evident.
