“…Furthermore, the average days in milk for cows culled because of metabolic diseases (113 DIM) and other reasons (115 DIM) were considered atypical because metabolic diseases in particular typically occur during early lactation [33]. The slaughter weights were also markedly low for these 2 groups (other reasons, 215 kg; metabolic disorders, 225 kg) as were the corresponding slaughter revenues (other reasons, 362 €; metabolic disorders, 440 €; average for all slaughtered cows, 535 €) [34,35]. These 2 groups had the highest percentage of condemned carcasses (37 % and 26 % partial condemnation and 18 % and 10 % whole carcass-condemnation), which was considered disproportionate and suggested that these cows were affected by chronic disorders [35].…”

Evaluation of the health records showed that many of these cows were diagnosed with and treated for digestive disorders that were identified on our initial data collection visit.…”

The manager of a large dairy herd (total confinement, total mixed ration feeding, 10130 kg milk sold per cow and year) requested a workup of a digestive disorder problem that had been ongoing for several years. The cows were at all stages of lactation, and the incidence proportion (events/100 cows at risk) of digestive disorders was approximately 5 to 10%. The clinical picture included an abnormal demeanor of varying severity and signs that differed among the cows. The latter included decreased milk production and physical activity, low body condition score, abnormal rumen motility and stratification, small intestinal dilatation, diarrhea, undigested fiber particles in the feces, fever and abdominal pain.The following approach was used to investigate the digestive disorder problem:1. The herd was assessed for production levels, housing requirements, feeding protocols and animal health management. The latter comprised evaluation of different animal scores, metabolic profile analysis, diagnosis of disease, culling records and slaughter data. The results revealed risk factors concerning the feeding and animal health monitoring, (e. g. in dry matter intake and silage quality management, disease detection and diagnosis in fresh cows). The assessment also identified a high occurrence of digestive disorders of unknown origin.2. Fifteen cows that represented the ongoing digestive disorder problem were selected to undergo clinical examination, hematological analysis, urinalysis, and ultrasonography of the ventral abdomen. The clinical examinations revealed different digestive disorders, which were mainly inflammatory in nature, in all the cows. Eight cows had localized reticuloperitonitis and 13 had left displaced abomasum with different degrees of displacement and adhesions between the abomasum and reticulum attributable to reticuloperitonitis.Our results revealed a multifactorial problem caused by several risk factors relating to animal health and feeding management protocols that resulted in different types of digestive disorders. The wires from damaged tires used to hold the pit silo tarps in place were identified as a possible traumatic cause of the reticuloperitonitis. Treatment, prevention and follow-up of the different conditions were discussed.

“…However, some animals suffering from diseases can be expected to have a reduced body weight before they are euthanized or die unassistedly, as weight loss is sometimes a consequence of disease due to, e.g., reduced feed intake (Alawneh et al, 2012;Hägglund et al, 2022). A recent study by Vlemminx et al (2023), found an association between health disorders observed at slaughter and a reduction in carcass weight. It is thus reasonable to assume that animals considered to be fit for transport and slaughter are in a better condition than the unhealthy animals dying on farm after suffering from disease (some of them being recumbent), which would most likely result in a weight loss for those animals.…”

Loss of animals is a considerable waste of resources in the meat supply chain, where quantitative data are scarce but critical for guiding improvements. In this study, we used material flow analysis to track the amount of beef diverted away from the food supply chain at the farm level. The beef losses (absolute and as the proportion of yearly initial production) were estimated from data on assisted and unassisted deaths of cattle on Swedish farms obtained from the central register of bovine animals for 2002–2021 combined with official statistics on slaughter weight. The fallen animals were grouped according to age, sex and breed, to enable estimations of the lost amount of carcass weight, both in total and per animal group. The yearly loss during primary production 2017–2021 was on average 13,000 ton carcass weight, or 8.5% of the initial production. No decreasing trend for the loss rate could be determined after 2015, when the Agenda 2030 target 12.3 (Halved food waste and reduced early losses) was introduced. Female dairy breeds showed greater beef losses than dairy males or beef breeds and crossbreeds of both sexes, and their beef losses mostly occurred at 4–5 years of age, thus constituting the hot spot group for lost beef. The results can serve as a base for directed reduction efforts.
