Vliv robotizovaného dojení na chování plemenic skotu / Effect of robotic milking on the behavior of breeding cowsBLÁHOVÁ, Lucie January 2011 (has links)
With increasing consumption of milk and milk products, there were increased number of dairy cattle, but the increase of demand for dairy cows and thus to changes in technology and technique of milking, which would increase milk production, productivity, and improve the welfare of dairy cows. An efficient solution could be milking robots. The first robot was placed on a farm in the Netherlands in 1992. The introduction of robotic milking on agricultural farms in the Czech Republic began in 2003 when the main reason was a shortage of skilled manpower that would be willing to work in harsh working and sanitary conditions. The thesis aim was to assess the effect of milking by the milking robot on the behavior of breeding cows throughout the day in relation to milk yield and fertility in relation to lactation and genotypic classification (H100, HxC, C100). The behavioral monitoring was carried out in dairy farms Brloh (milking by milking robots) and Haklových Dvorech - the control group (in the milking house) in the period from August 2009 to January 2010. The data processing was done with using the Microsoft Excel program. For the evaluation of all parameters were observed in herds calculated basic statistics. Differences disappear individual indicators were evaluated single-factor analysis of variance. The first monitoring of the findings in cattle reproductive performance was the terms of genotype. The values were found favorable for fertility groups HxC in the both stables. Length insemination interval reached 69.1 days in ZD Brloh (compared to 110.1 of the ŠZP Haklovy Dvory), length of service period of 110.8 (vs. 142.9 days). In the meantime, the length (due to differences in the number of animals in the group) was a length of 409.5 versus 438.5 in the group of breeding cows milked in a milking house (ŠZP Haklovy dvory). Further indicators of fertility were evaluated in terms of lactation. The longest length of service period was recorded at 1st lactation in ŠZP Haklovy Dvory were 176 days. The shortest service period was found at the 3rd and subsequent lactations of 133.5 days. Insemination interval, indicating the search of breeding cows, which were in a rutting season, was roughly the same at all lactation ZD Brloh (range 72.7 to 78.2 days) for the ŠZP Haklovy Dvory was the longest period of time to 2 lactation (118.9 days). In terms of breeding cows for milk yield for each lactation cows achieve greater results in the production company with robotic milking (100 days - 3539.1 kg, 200 days - 6727.5 kg of milk 305 days - 9602.9 kg of milk). Compared to the control group, where a 100 days lactation cows milked 3240.06 kg of milk 200 days produced 5433 kg to 305 of milk and 5327.18 kg of milk daily. The behavioral surveillance in both companies was carried out for 24 hours using the interval method with a 10 minutes interval period. The largest part of the day the cows were lying. The second largest dairy operations were the category of standing, which represented the average length of 6.05 hours in ZD Brloh. In the ŠZP Haklovy Dvory was the time period 5.71 hours. The significant period between groups is also the time of feeding, which in the system with the milking in milking house is much shorter by 1.79 hours and it taken 3.71 hours. The length of the movement was in the milking house more than half the size shorter and was 0.32 hours. Also, the length of staying in the milking house was about half shorter and it was 0.22 hours.

Vybrané parametry welfare dojnic ve vztahu k dojení dojicím automatem. / Selected welfare parameters of milk cows in relation to milking by a robot.PRŮŠA, Jan January 2015 (has links)
The aim of this work was to gather and evaluate the evidence about the behaviour of dairy cows during the milking by a robot (including physiological reactions running after the milking). The following parameters were observed: number of milking per 24 hours, the time from onset to the robot and the teat cup deployment, the time between milking, the total time of milking, milk yield with each milking, average and total milk yield per day. The results were measured separately in heifers and in cows on the second and subsequent lactations. In the same time, there was also observed the behaviour of cows after leaving the milking robot - feed and water intake, physical activity and the rest for the time of 30 minutes after the milking. Simultaneously, there was also observed the effect of milking technology for the health of the cows, focused on diseases of the mammary gland. There were three ethologic observations which always lasted 24 hours. In addition to the observed data, there were evaluated the data records obtained from the milking machine (e. g. milk yield per one milking, the interval between single milkings, etc.). There were observed an average of 60 pieces of cows. Throughout the watching the cows in the barn behaved calmly and contentedly. They came to the milking machine spontaneously, only a few cases had to be herded for milking by the caregiver. However, they were all the heifers which did not have the sufficient experience with the milking. The counting of teat cup deployment attempts had to be abandoned because of the close proximity of the observer at the milking robot. In this case, the cows were not quiet and did not want to go in the robot spontaneously. The mammary gland disease was diagnosed at an average of 6.9 pieces of milked cows per one month. This high number of cases is ascribed to a poor hygiene of the stables and a poorer quality of feeding. This work was created in cooperation with the grants NAZV QJ1210144 and NAZV QJ1530058.

Porovnání vybraných ukazatelů welfare dojnic dojených v dojicím automatu a na rybinové dojírněKOUTEK, Martin January 2016 (has links)
The aim of this diploma thesis was to obtain and formulate the knowledge about the process of milking and the activity of dairy cows 30 minutes after milking in the milking parlour with a robot and in the herringbone milking parlour. Three ethological observations took place in three seasons. The observation on the farm with a milking robot took 24 hours continuously. The observation on the farm with a milking parlour lasted for the duration of milking and subsequent observation of the last group of dairy cows. In total, there were evaluated 452 successful milkings on the farm with the robot and 112 successful milkings on the farm with the milking parlour. Crosses of Czech Fleckvieh Breed and red Holstein Breed in the same ratio were observed during the monitoring. Parameters during milking and ethological performance, such as drinking, feed intake and lying down, in the duration of 30 minutes after milking were monitored. The instructions of the thesis are based on the project NAZV - QJ1210144 and NAZV QJ1530058.

Využití provozní kapacity dojících robotů v systému svobodného pohybu zvířat. / The Exploitation of Functional Capacity of Robotic Milking Machines in System of Free Moving Animals.REICHOVÁ, Sandra January 2010 (has links)
The aim of the thesis was to assess objectively the exploitation of the functional capacity of milking machines in the system of free moving animals. There were data coming from seven agricultural companies analysed in the thesis. The data collection took place from January to November 2009. We were provided with the preliminary data by the individual farms taking part in a programme called T4C. The information on problematic dairy cows comes directly from their breeders. The average production of the dairy cows was the first assessed criterion. The highest production (28.79kg) was achieved by little private agricultural companies. The lowest production (25.22kg) was ascertained in middle-sized companies. As far as the breed of dairy cows is concerned, the Holstein dairy cows gave the highest possible amount of milk (40.43; 30.16 a 27.01 kg). The CRV Fleckvieh cattle dairy cows gave the lowest possible amount of milk (24.83; 21.04 a 22.74 kg). The assessment of the number of milking by means of the robotic milking system represents the next criterion. Little private agricultural companies showed the highest frequency of milking (140.88). Whereas the big agricultural companies showed the lowest frequency of milking (119.28). Mostly the Holstein dairy cows were milked by the robotic milking machines (130.34). On the other hand, the CRV Fleckvieh cattle dairy cows were milked least by the robotic milking machines by contrast (107.94). The middle-sized agricultural companies achieved the highest number of milking per dairy cow, per day (2.47). The little private agricultural companies proved the lowest number of milking per dairy cow (2.34). The mixed herds of the Holsteins and CRV Fleckviehs proved the rate of 2.47. The Holstein dairy cows showed the milking frequency 2.45 per day while the CRV Fleckvieh dairy cows 2.32. The dairy cows from the big agricultural companies went to be milked by the robotic milking machine most frequently from the point of view of willingness, what follows is that these dairy cows showed the highest number of refusals per one milking (2.19). The lowest values of this criterion were shown in little private agricultural companies (1.10). With reference to the breed, the values of this indicator proved the lowest number of refusals (1.85) whereas the CRV Fleckviehs showed the highest number of refusals (2.25). The exploitation of the time capacity has been proven as the most effective one - 78.61% in little private agricultural companies. Whereas the lowest time exploitation has been proven in big agricultural companies - 68.11%. As far as the cow breed is concerned, it was ascertained that the Holstein dairy cows were milked longest -73.21%. On the other hand the CRV Fleckviehs were milked shortest - 63.17%. The highest amount of the dairy cows that needed to by accompanied to the robotic milking machine was recorded in big agricultural companies - 20.1%. Remarkably lower number of problematic cows was ascertained in middle-sized agricultural companies - 9.7%. The number of problematic cows in little private agricultural companies proved to be similar to the number in middle-sized agricultural companies 9.3%. It was ascertained that the most problematic dairy cows came from the mixed herds - 18.7%. The CRV Fleckviehs were the least problematic - 8.8%.

Porovnání vlivu technologie ustájení a dojení na vybrané ukazatele užitkovosti a kvality mléka / Comparing the impact of housing and milking technologies on selected indicators of performance and quality of milkPOLÁKOVÁ, Radka January 2010 (has links)
The theme of this thesis is to compare free housing with a milking robot, milking of serious housing in the pipeline. The evaluation is focused on milk yield and its quality, reproductive performance and health. It is also monitored by the free choice of milking cows during the day. Consideration is also observed in stable microclimate. Everything is assessed under operational conditions. Object of study is a refurbished barn, where both systems are in operation. Were measured and compared observed values of milk production, reproduction and health status between groups. The observed values were evaluated in the program Statistica 9th of a computerized milking robot system was speciaed the period of time when Nada dairy milk provides the most of milk through a robot.. In the area of dairy cattle milking robot reaches a higher milk yield and increasing the percentage of lactose recovery. Milking stalls of the pipeline has better results in the percentage of protein recovery. The choice of time period of milking cows, the most milk by dairy cows wasprovided between 10:00-18:00 pm. In the area of reproduction achieved better results with loose housing milking robot. The issue of health status showed a statistically better health outcomes for the free housing with a milking robot.

VLIV POČTU DOJENÍ NA UŽITKOVOST A PLODNOST PLEMENIC DOJENÝCH POMOCÍ ROBOTŮ / The Influence of milking frequency on milk efficiency and fertility in breeding cows, milked by the help of automatic milking systemsKOZELKOVÁ, Jitka January 2011 (has links)
The aim of this thesis was to analyze the effect of milking frequency per day on milk efficiency and fertility during the course of lactation. The observation of dairy Holstein cattle herd took place in agricultural company Brloh (Blanský les Region) from January 2010 to February 2011. There were observed 55 dairy cows: Holstein cattle (75 %), share cross cows with race Czech Pied cattle (22 %) and Fleckvieh cattle (3%). Microsoft Excel has been used for processing the statistic data. For results evaluation, some basic statistic characteristics have been counted. Differences between the groups have been verified by the simple factor analysis of variance. By evaluation of milk efficiency including milk constituents for standardized lactation on individual lactation phases, reached breeding cows on first lactation 9460.00 kg M (3.22 % B and 3.88 % T), on second lactation 10632.15 kg M (3.23 % B and 3.96 % T) and breeding cows on third and next lactation 9738.60 kg M (3.18 % B a 4.08 % T). In the assessment of milking frequency visited breeding cows the AMS on the first lactation at 1/3 lactation phases 2.51 per a day, breeding cows at 2/3 lactation phases 2.72 per a day and 2.70 per a day at 3/3 lactation phases. This trend continued in next lactation, but breeding cows on the second lactation at 3/3 lactation phases visited most often robotic milking machine 2.80 per a day. Relationship between the number of milking and milk efficiency was found statistical significance. With the increasing number of milking performance also increases. By evaluation reproductive parameters the following values were observed ? the average first calving age 774.9 days (25 months), the average meantime 382.3 days, the average servis period 110.4 days and the average insemination period 77.8 days. The relationship between the number milking and service period has been established by the positive correlation, i.e. to the growing number of milking is to the extension service period.

Au pied des collines montérégiennes, des robots : ethnographie de systèmes agricoles automatisésLaugier, Manuel 05 1900 (has links)
La production laitière au Québec se distingue des autres régions d’Amérique du Nord par son organisation autour de fermes familiales de taille relativement restreinte. Cette réalité découle d’une histoire agricole particulière, marquée par l’aménagement du territoire hérité du modèle seigneurial ainsi que par la mise en place d’une gestion de l’offre couplée à un important protectionnisme fédéral et provincial. Néanmoins, depuis la fin du XXe siècle, le secteur laitier québécois fait face au défi de la libéralisation des accords commerciaux et aux questions d’éthique environnementale et animale. Dans ce contexte, le robot de traite est présenté par ses constructeurs et les pouvoirs publics, comme un moyen de résoudre ces défis. En effet, si plusieurs études concernant cette machine indiquent que de nombreux producteurs tirent certains bénéfices en termes de résultat économique et de qualité de vie, d’autres montrent également que son implantation et ses impacts fluctuent en fonction du contexte politique et socioculturel des régions étudiées.
Cette recherche vise à approfondir l’étude de cet équipement agricole en prenant en compte ses dimensions symboliques à l’échelle de la région de la Montérégie. En adoptant une approche sociographique de la technique, l’objectif est de mettre en lumière les relations sociales et les enjeux de pouvoir qui se nouent autour de l’outil. L’étude montre notamment que le robot de traite permet de valoriser un certain ethos industriel mobilisé par les producteurs en vue de la transmission familiale de la ferme ainsi que dans la lutte symbolique face aux firmes industrielles dominant le secteur laitier québécois. Le concept de capital d’enracinement est notamment proposé afin d’aborder l’expression des sentiments de fierté et de responsabilité liés aux héritages familiaux et professionnels. Il en découle des tensions entre les aspirations d’ancrage local et de mobilité des acteurs, ainsi que parmi les différentes temporalités qui se manifestent autour de l’objet, principalement entre le désir d’optimisation permanente du système de production et les obligations, morales et financières, concernant le passé et l’avenir de ces familles. / Dairy production in Quebec differs from other parts of North America by its organization around relatively small family farms. This reality results from a particular agricultural history, marked by the territorial development inherited from the seigneurial system as well as the implementation of supply management coupled with significant federal and provincial protectionism. Nevertheless, since the end of the 20th century, the Quebec dairy sector has faced the challenge of liberalizing trade agreements and questions of animal and environmental ethics. In this context, the milking robot is presented by manufacturers and public authorities as a means of solving these issues. Indeed, if several studies concerning the milking robot indicate that many producers derive certain benefits from it in terms of economic results and quality of life, others also show that its implementation and its impacts fluctuate according to the political and sociocultural context of the regions studied.
This research aims to deepen the study of this agricultural equipment by considering its symbolic dimensions at the scale of the Montérégie region. By adopting a sociographic approach to the technique, the objective is to shed light on the social relations and power issues that arise around the tool. In particular, the study shows that the milking robot makes it possible to valorize a certain industrial ethos of the producers mobilized around the family transmission of the farm as well as in the symbolic struggle against the industrial firms dominating the Quebec dairy sector. The concept of rooting capital is proposed in order to address the expression of feelings of pride and responsibility related to family and professional legacies. Tensions arise between the aspirations of local anchorage and mobility of the actors, as well as among the different temporalities that manifest themselves around the object, mainly between the desire for permanent optimization of the production system and the moral and financial obligations concerning the past and the future of these families.
