The purpose of this study is to evaluate the effect of housing systems (free vs. tie-stall) and season (winter vs. spring) on the welfare of dairy cows through indices of cleanliness, leg health (straightness, hocks and knees), lameness score, body condition and milk production. This is to test the hypothesis that dairy cows in spring and free-stalls have a better quality of well-being than those kept in tie stalls in winter. For that, 299 dairy cows of the Holstein and Montbeliard breeds were selected from dairy farms in 6 communes of the Constantine governorate in eastern Algeria. The results showed that tie-stalled farms in winter were characterized by a lack of hygiene (P <0.001), with a stall cleanliness score of 7.62 and a frequency of 32.60% of dirty to very dirty cows. In the spring, the incidence of severe lameness does not exceed 9% in farms with tie stalls and more than 41% in mild lameness in housing with free stalls (P <0.001). Cows in tie stalls show a deviation of legs of 17° to 24° (57.97%). On the other hand, more than half of cows in free stalls show integumentary lesions (alopecia and swelling) of the carpal (60.25%) and tarsal joints (54.22%) (P <0.001). The percentage of fairly lean cows (score 2-2.5), housed in tie stalls, was significantly higher (18 to 44%) with a significantly low milk production (P <0.001). These results reflect a lack of comfort in tie-stall farms during winter which has an impact on dairy performance.

Questions and uncertainties characterised the accession period of Hungary to the European Union. It is evident that only those producers can compete on the market who produce good quality products. Therefore, only dairy farms with extra high quality raw milk production will be successful. Furthermore, on this basis, rural areas will be able to keep their inhabitants one of the most important problems presently. The author examined the process of milk production and the labour efficiency of 18 dairy farms in Hajdú-Bihar County. Mechanization, the quality of the work force and the system of incentives were assessed. Data of produced milk quality were collected too. Because of farms with different types and sizes the circumstances of milk production differ greatly. As a result of data analysis it was found that the working schedule of small and large farms often differed. The most important working processes (milking, feeding, harvesting) are done by family members. In order to increase the efficiency and improve working atmosphere the improvement of wage and incentive systems would be desirable. Labour efficiency indexes show that the efficiency of tie-stall systems is lower than the efficiency of similar size loose-housing systems. It can also be stated; that labour efficiency of similar size loose housing dairies differs greatly so the importance of work-studies should be increased.

Technical And Economic Indicators

При выборе типа доильной установки и ее размера необходимо учитывать максимальное планируемое поголовье дойных коров и размер технологической группы, кратность и время одного доения, продолжительность рабочей смены дояров. Анализ технико-экономических показателей наиболее распространенных на сегодняшний день типов доильных установок одинакового технического уровня свидетельствует, что наилучшие удельные показатели имеет установка типа «Карусель» (1), а установка типа «Елочка» (2) требует более высоких затрат труда и средств. Установка «Параллель» (3) занимает промежуточное положение. Из анализа пропускной способности и количества необходимых операторов: установка 2 рекомендована для ферм с поголовьем дойного стада до 600 голов, 3 — не более 1200 дойных коров, 1 — более 1200 дойных коров. «Карусель» — наиболее рациональный, высокопроизводительный, легко автоматизируемый и, следовательно, перспективный способ доения в залах, особенно для крупных молочных ферм. The choice of the proper type and size of milking installations needs to take into account the maximum planned number of dairy cows, the size of a technological group, the number of milkings per day, and the duration of one milking and the operator's working shift. The analysis of technical and economic indicators of currently most common types of milking machines of the same technical level revealed that the Carousel installation had the best specific indicators while the Herringbone installation featured higher labour inputs and cash costs. The Parallel installation was found somewhere in between. In terms of the throughput and the required number of operators Herringbone is recommended for farms with up to 600 dairy cows, Parallel — below 1200 dairy cows, Carousel — above 1200 dairy cows. Carousel was found the most practical, high-performance, easily automated and, therefore, promising milking system for milking parlours, especially on the large-scale dairy farms.

This study aimed to evaluate the general quality of life (QoL) of Brazilian vegetarians. A cross-sectional study was conducted with Brazilian vegetarian adults (18 years old and above). Individuals were recruited to participate in a nationwide online survey that comprised the WHOQOL-BREF as well as sociodemographic and characterization questions related to vegetarianism. The WHOQOL-BREF is composed of 24 items which are divided into four domains (domain 1: physical health; domain 2: psychological well-being; domain 3: social relationships; and domain 4: environment), plus two general items which were analyzed separately, totaling 26 items. The answers from the questionnaire were converted into scores with a 0–100 scale range, with separate analyses for each domain. Results were compared among groups based on the different characteristics of the vegetarian population. A total of 4375 individuals completed the survey. General average score results were 74.67 (domain 1), 66.71 (domain 2), 63.66 (domain 3) and 65.76 (domain 4). Vegans showed better scores when compared to the other vegetarians, except in domain four, where the statistical difference was observed only for semi-vegetarians (lower score). Individuals adopting a vegetarian diet for longer (>1 year) showed better results for domains one and two, with no difference for the other domains. Having close people also adopting a vegetarian diet positively influenced the results for all domains. On the other hand, it was not possible to distinguish any clear influence of the motivation for adopting a vegetarian diet on the scores’ results. Adopting a vegetarian diet does not have detrimental effects on one’s QoL. In fact, the more plant-based the diet, and the longer it was adopted, the better the results were.

Identification of risk factors is important for the design of control programmes for mastitis in cows. Information about farms and management was collected at a farm visit. California Mastitis Test (CMT) was performed to assess sub-clinical mastitis, and cows, udder and milk were examined for clinical mastitis. A total of 347 lactating cows from 83 farms in the dry season (November - February) and 388 lactating cows from 89 farms in the wet season (June - October) were studied. The overall prevalence of mastitis was 19.9% and 44.8% in dry and wet seasons, respectively. The prevalence of mild mastitis was 17.3% and 40.7%, whereas that of moderate mastitis was 2.6% and 4.1% in dry and wet seasons, respectively. The prevalence of mastitis was higher (P<0.01) in wet than in dry season. On average, 18.7% quarters had mastitis during the wet season and 6.9% in the dry season. In the dry and wet seasons, respectively, 63.9% and 11.2% had completely dry floors, and the prevalence of mastitis was 22.6% and 30.0%. On the other hand, 88.8% and 36.1% of 83 farms had partly or completely wet and soiled floor and the prevalence of mastitis was 40.0% and 59.5% in the dry and wet seasons, respectively. Udder cleanliness, milk yield and peri-parturient diseases significantly (P<0.01) increased the risk of mastitis. The prevalence of mastitis is regarded as quite high. Dry and clean floor to keep cow's udder and teat clean would help control mastitis in the dairy farms of Bangladesh. DOI: 10.3329/bvet.v26i2.4951 Bangl. vet. 2009. Vol. 26, No. 2, 54-60

Recent Developments

This paper provides an overview of recent developments in rearing conditions, health and welfare issues of dairy cows. The last approximately 30 years has witnessed worldwide increasing scientific research, consumer activity, and political response towards housing condition, health and welfare issues of dairy cattle. All buildings and housing systems for dairy cattle should be designed, constructed, maintained and managed to assist in the achievement of the Five Freedoms: freedom from hunger and thirst, freedom from discomfort, freedom from pain, injury and disease, freedom to express normal behavior and freedom from fear and distress. Whether dairy cows are housed in cubicles, straw yards or cow sheds, in order to maximize their performance and to ensure satisfactory standards of welfare, the accommodation must provide the most basic behavioral and physiological needs. As an absolute minimum, the housing must provide a comfortable, clean, well drained and dry lying area together with shelter from adverse weather. Also, it must allow the cow to move freely around without risk of injury and certain diseases. If the housing system does not provide for these basic needs, then not only will health, welfare and production of dairy cattle be compromised, but it is likely that failure to comply with the welfare codes and the law relating to animal welfare will occur.

AbstractThe reduced fertility that is becoming more evident in high yielding dairy cows may be related to many factors including changes in milk production, food intake and fluctuations in body condition. Metabolic and production markers have been studied as a way of predicting success to a particular artificial insemination. Successful conception to a particular service was not associated with milk production, body condition or plasma concentrations of several indicators of metabolic state around the time if insemination. This highlights the importance of time of information collection in fertility management programmes. Increased food intake may reduce systemic progesterone concentrations. This is more evident in sheep than cattle, but a positive relationship between systemic progesterone early post mating and establishment of pregnancy in cattle has been reported. However, progesterone concentrations in the ovarian vein and endometrium are not strongly correlated with systemic progesterone. Thus, the significance of modest changes in systemic progesterone in affecting oocyte and embryo development must be questioned. Blood urea concentrations can be altered by diet, and reduced pregnancy rates have been reported in cows with high urea concentrations. However, in other recent studies, no difference was reported in serum urea in cows that conceived and those that failed to conceive. Pregnancy rate was equally high in heifers when in-vitro produced embryos were transferred to heifers on high and low urea diets. When embryos were produced in sheep on high and low dietary urea, the effects on embryo development appear to occur early in the developmental process, suggesting a substantial effect on the development of the oocyte. The developmental capacity of oocytes and quality of embryos is reduced in cattle maintained on extremely high dietary intakes. Oocyte developmental capacity is reduced in cows of higher genetic merit and embryo quality can be substantially reduced in the early postpartum period. Collectively, these results suggest that high dietary intake or high metabolic load is deleterious to normal oocyte development and establishment of pregnancy. This highlights the importance of further studies on the effect of dietary intake on metabolic state and follicle, oocyte and embryo development. In a practical context, these results highlight the importance of nutritional management and avoiding changes in the amount or type of diet around the time of mating in high-production dairy cows.

The present study was conducted to investigate the milk quality from different genotype. A total 48 dairy cows belong to different genotypes such as Holstein cross, Jersey cross, Sahiwal cross and Red Chittagong were selected. Milk compositional viz. specific gravity, Acidity test, Fat test, Protein test, Solids-not-fat (SNF) test and total solids (TS) test were carried out. It was observed that the higher specific gravity of milk was obtained from Jersey cross and Red Chittagong genotype, which was significantly higher (P<0.01) than the other genotype of dairy cows. The highest acidity (%) was observed (0.165±0.014) in Red Chittagong and the lowest acidity (0.118±0.025) in Sahiwal cross. The highest fat (%) was observed from Red Chittagong cows milk which was statistically higher from Jersey cross and Sahiwal cross and the lowest fat (%) was found in the milk of Holstein cross cows. The highest SNF value was obtained from Jersey cross and the lowest from Sahiwal cross. On the other hand, Holstein cross and Red Chittagong was nearly similar. Red Chittagong milk sample showed the highest TS value and the lowest value was observed from Holstein cross. The highest protein value was found from Red Chittagong and the lowest from Holstein cross but the protein content of other two genotypes were nearly similar.

The Impact

AbstractPhysical activity provides many benefits in patients with congenital bleeding disorders. Patients with hemophilia are encouraged to participate in exercise and sports, especially those patients receiving prophylaxis. Several publications and guidelines have explored this issue in hemophilia patients, evaluating in particular the impact of physical activity on patients' well-being and quality of life. The other rare congenital bleeding disorders are less studied; they are heterogeneous in terms of clinical bleeding phenotype, incidence of hemarthrosis, and arthropathy. Furthermore, prophylaxis in these patients is less common than in hemophilia patients, which must be considered when choosing the type of physical and sporting activity. In this review, the authors have analyzed the literature focusing their attention on those rare coagulation disorders that may be complicated by arthropathy and the role of exercise and sports in this context.
