1 Feeding cattle means feeding people

Feeding cattle means feeding people 1 Feeding cattle means feeding people The world’s population is constantly growing, and so are global food needs. The increasing purchasing power of people in many countries is leading to an increase in the demand for food of animal origin. This causes major challenges for agriculture and its upstream and downstream sectors, as the resources required for livestock farming, such as soil, water and fossil fuels, are limited. Furthermore, food production has to compete with a growing demand for non-food goods such as bioenergy. “Dairy farming contributes to...

Feeding cattle means feeding people If cows produce milk for longer and have as many lactations as possible, fewer cows will need to be replaced. This reduces the feed costs per kg of milk produced and also improves the efficiency and sustainability of milk production overall. Fig. 1: The more often a cow calves, the more efficient and sustainable the milk production. The production capacity of dairy cattle has increased impressively in the last 50 years. The flip side, however, is that this has been linked to a significant fall in the fertility, reproductive performance and productive...

Higher requirements for feed 2 Higher requirements for feed Feeding dairy cattle properly has never been easy. Due to the high output potential of today’s cattle, however, it seems harder than ever. For modern animal nutrition, optimal cattle feed in the relevant performance phase is the key to success. 2.1 Lifetime yield and productive lifetime The highest possible lactation output is an absolute priority when breeding dairy cattle today. Selecting high-yield cows has not taken into account metabolic load. This focuses completely on milk production and other physical functions are...

Higher requirements for feed non-esterified free fatty acids in the blood and a drop in blood glucose levels. The liver cannot mobilize these free fatty acids sufficiently, resulting in an accumulation of fat in the liver and an increase in ketone bodies in the blood. “The extreme metabolic changes during the transition phase can endanger the health of the cows.” Many cows are unable to overcome these extreme metabolic changes without damage. The consequences are typically metabolic disorders, which can often trigger a whole range of illnesses, such as ketosis, milk fever, mastitis,...

Challenges in milk production 3 Challenges in milk production The metabolism of dairy cows is very different from that of other types of livestock. Getting feed right for high-yield cows is often a balancing act. This practical guide thus presents some metabolic processes and their relevance in more detail and explains how they arise. 3.1 Fat metabolism During the negative energy balance at the start of lactation, dairy cows mobilize large amounts of body fat. This can be seen in weight loss, deterioration in body condition and an increase in milk fat content. However, cows have large...

Challenges in milk production When milk yield increases, glucose requirements therefore increase. Insufficient formation of glucose presents a bottleneck to maintaining energy metabolism. Glucose is therefore the main focus during this time. “Insufficient formation of glucose presents a bottleneck to maintaining the energy metabolism of dairy cows.” Under normal conditions, blood glucose levels are regulated very evenly by hormones. However, particularly in the first few weeks after calving, very low blood glucose levels can be observed. Studies on various dairy cattle breeds have shown...

Challenges in milk production 3.5 Inflammation and oxidative stress In order to mobilize body tissue quickly in times of acute shortage, cows switch to inflammation mode. Studies suggest that this applies to high-yield cows in particular. This is likely to be a result of breeding for high yields in the first 100 days. As well as mobilizing body tissue as an efficient source of milk fat, for example, inflammation mode also produces substances that the body needs in order to fight infections. These substances oxidize or destroy infectious agents, but can also cause damage to adjacent tissue....

Challenges in milk production Therefore, if a cow withstands the transition but is in a weak state, hormone regulation mechanisms in the metabolism prevent it from getting into calf again. Maximum milk yield takes priority here first, which is why the time until the first cycle is delayed. This leads to the cow not showing signs of heat and to weak corpus luteum. Plasma concentrations of progesterone that are too low can also trigger spontaneous abortions. These symptoms can be treated by a vet. However, it is much more important to eliminate the causes of such fertility problems. Farmers...
