“…Furthermore, the dairy farm-workers’ correct perception about the influence of poor milk yield and mastitis on culling of dairy cows resembles previous reports which noted milk yield losses as a risk factor for culling dairy cows (Orpin and Esslemont 2016 ; Horváth et al 2017 ; Kerslake et al 2018 ). Mastitis directly influences milk production in dairy farms and also increases production costs (Harmon 1994 ).…”

Milk serves as a significant source of protein for many families and aids in combating food insecurity. However, the demand for milk and milk-related products far exceeds the supply. The objective of the study was to evaluate dairy farm-workers’ knowledge of factors responsible for culling and mortality of dairy cows in the Eastern Cape Province. Data was collected from 106 dairy farm-workers using a questionnaire. Any correctly answered question by the majority amounted to a point and a zero for incorrectly answered questions. Correct answering by the majority to more than half the questions of a subsection amounted to a pass. A less than 50% pass rate was considered a poor level of knowledge, 51–69% pass rate was considered an average level of knowledge, and anything higher than that was considered a good level of knowledge. Most farm-workers (66.0%) relied on their colleagues for dairy health information. Most dairy farm-workers (49.1%) indicated that lameness, milk fever (56.6%), and mastitis (47.2%) do not lead to culling and mortality of dairy cows. A majority (83%) of farm-workers agreed that reproduction problems, poor milk yield (77.3%), and age (81.1%) are the main reasons for culling dairy cows. The participants had varying perceptions and limited knowledge (28.3%) about the major contributing factors of culling and mortality. The lack of training courses and minimal use of other sources of information such as the internet might contribute to this poor knowledge and perceptions.

“…Milk yield per cow is one of the main factors influencing the economics of dairy cattle production (Nemeckova et al 2015;Krpalkova et al 2016). High milk yields mean high incomes but might also contribute to poorer cow health and fertility and, as a result, to increased culling rate (Horvath et al 2017a). The profitability of dairy farms also depends greatly on the reproductive efficiency of dairy cows and the optimal length of the calving interval (Dono et al 2013).…”

Milk production is one of the most important areas of the Czech agrarian sector, as evidenced by its 50% share (at 2017 prices) in revenues from livestock production. As for any business, a certain level of profitability is a prerequisite for long-term and sustainable development of dairy farms. This study’s aim was to evaluate the economic efficiency of milk production from both Czech Fleckvieh (C) and Holstein (H) cows based on data collected each year from 48 to 70 Czech dairy farms in the period from 2012 to 2017. Total costs per feeding day and litre of milk, level of profitability, and income over feed costs were calculated. The influences of herd size and milk yield on profitability and break-even points were examined while sensitivity analysis and model calculations were utilised to predict profitability. The farms with higher average milk yields (>7 500 and >9 500 L per lactation for C and H, respectively) had higher costs per feeding day, lower costs per litre of milk, and improved profitability (p < 0.05). Average break-even points were estimated for milk price (0.31 and 0.32 EUR) and milk yield (7 257 and 9 209 L) in C and H herds, respectively.<br />

“…0.13 and 0.09, respectively. As Horvath et al (2017) demonstrated, the duration of lactation may determine the frequency of culling, as an increase in its length is accompanied by an increase in the percentage of cows culled due to reproductive disorders. The present study has shown no statistically significant differences in the duration of lactation, which ranged from 262 (genotype CT) to 272 (genotype CC) days.…”

“…This is confirmed by findings presented by other authors (Brickell and Wathes 2011;Litwinczuk et al 2016;De Vries and Marcondes 2020), who demonstrate that the actual length of cow productive life has been shorter than the natural lifespan in recent years. Brickell and Wathes (2011) demonstrated that 43% of cows were culled before the third calving, and Horvath et al (2017) showed that as many as 26% of cows were culled during the first lactation. The productive life of cows in the herd should span from five to eight lactations, which indicates that the cows from the analysed herd were culled too early, as the average number of lactations ranged from 3.78 to 4.31 (in the animals with genotypes TT and CC, respectively).…”

This research paper addresses the hypothesis that the peptidoglycan recognition protein 1 (PGLYRP1) gene polymorphism (Tyr76His; dbSNP ID: ss104796364) has an influence on some performance traits and causes of culling in Polish Holstein-Friesian red-white cows. The study involved 134 cows kept on a farm in the southwest of Poland. PGLYRP1 genotypes TT, CT, and CC were detected. It was shown that compared with cows with genotypes CT and TT, the individuals with genotype CC were characterised by higher lifetime yields and higher amounts of lactation milk, fat, and protein. A beneficial effect of genotype CC, compared with genotype TT, was also noted in the case of the lifespan and, consequently, the length of the productive life and the average number of lactations. Diseases of the musculoskeletal system (genotypes CC and TT) and disorders of the reproductive system (genotype CT) were the most common causes of culling. An essential practical observation was the potentially higher susceptibility of cows with genotype CC to mastitis, which resulted in the necessity to cull over one-fifth of the animals in this group. Simultaneously, no cows in this group were culled due to low performance or metabolic, gastrointestinal, and respiratory diseases. Therefore, the PGLYRP1 gene seems to be a promising potential herd health marker; however, to consider it the main gene, it is necessary to extend the investigations to include more individuals and other breeds of dairy cattle.
