“…Establishment of different feeding groups allows the farmers to adjust the rations for specific feeding requirements in particular lactation stages. Dairy cows of different feeding groups receive concentrates according to their milk yield and the risk of under- or overconditioning is therefore reduced [ 47 , 48 , 49 ]. Provision of high amounts of concentrate feeds (>8.5 kg/day) predictably reduced the risk for low body condition score.…”

The objective of this study was to examine the effects of housing and management factors on animal welfare indicators in dairy cows using a benchmarking approach. In total, 63 conventional dairy cattle farms with zero-grazing in Northern Germany were assessed using selected animal welfare indicators (body condition score, integument alterations, lameness, milk somatic cell count, and social behaviour) of the Welfare Quality® protocol. Additionally, housing characteristics such as designs of barns, cubicles, and floors were documented during farm visits and farmers were interviewed concerning their common management routines. Farms were categorized into a high welfare or low welfare group by calculating upper and lower tertiles for each of the animal welfare indicators separately. Both groups were compared regarding housing conditions and management practices using univariable and multivariable logistic regressions. Several associations between housing and management factors and animal welfare indicators were demonstrated in univariable analysis (p < 0.20). Significant effects within multivariable logistic regression analysis were determined for lameness (routine use of foot-baths), milk somatic cell count (milking frequency) and social behaviour (cow-to-stall ratio) (p < 0.05). Comparing farms with higher and lower animal welfare status can provide useful information about effective options to improve animal welfare.

Some needs to increase the efficiency of dairy production affect improvement of nutrition technology. In addition to constantly expanding the offer of liquid feed additives that complement nutrient deficiencies in the diet, manufacturers are introducing more and more innovative devices for dispensing them. The changing ambient temperature at which liquid feed additives are fed may affect their dispensing quality. Therefore the aim of this study was to determine the temperature effect of various liquid feed additives on the accuracy of their dosing in a feeding station for dairy cattle. To reach the aim of the study the test stand was built basing on the feeding station for dairy cattle. The test stand was equipped with a DeLaval membrane feeder GD 500. The operation of the feeder was based on the principle of the diaphragm pump. To determine the accuracy of dosing by the fodder membrane feeder the dosing accuracy indicator was determined. Three different liquid feed additives were used to check the inaccuracy of dosing. The tests were carried out for four different temperatures of feed additives. The highest mean value of dosing inaccuracy (about 10 %) was achieved with Glycol Plus at the temperature of 20 ºC. The results of the experiment showed the statistically significant effect of temperature and feed additive type on the dosing accuracy. As a result of the investigations it was found that in addition to the density of preparations changes in the accuracy of their dosage may be influenced by their other physical properties.
