“…Teat measurements were similar to those reported by Mallam et al [29]. The FTL and RTL were similar to those reported by Ceyhan et al [33] for Holstein Friesian, which were 6.05 ± 0.10 and 4.89 ± 0.00 cm, respectively. This similarity is an indication that teat length has no relationship with the milk production potential of a cow.…”

The study examined the relationship between milk yield and udder morphology traits in White Fulani cows. Fifty-eight apparently healthy cows in early lactation at 2nd, 3rd, and 4th parity were used in the study. The data obtained from the cows were test day milk yield (TDMY) from single milking and udder morphology traits comprising udder length (UL), udder width (UW), udder depth (UD), fore teat length (FTL), rear teat length (RTL), fore teat diameter (FTD), and rear teat diameter (RTD). There was no significant effect of parity on TDMY or the udder morphology traits. Phenotypic correlations between TDMY, UL, UW, and UD were positive and significant. Notably, phenotypic correlations between UL and TDMY at different parities were the strongest. Teat measurements had no significant correlation with TDMY. Stepwise and principal component regressions were implemented to assess the relationship between milk yield and udder morphology traits. Interestingly, UL was the only trait that entered the reduced models. The results suggest a probable genetic correlation between milk yield and udder length. Therefore, since udder conformation traits are heritable, when selecting for udder length in White Fulani cows, a correlated response in milk yield is expected.

“…Similarly, higher parity dams tend to have higher milk yields (Ceyhan et al, 2015), that was previously demonstrated by several other authors, whereas highest yields were observed at 4 th or 5 th lactation (Mellado et al, 2011). Furthermore, dams' parity could also affect performance of their daughters (Mikláš et al, 2020), as Storli et al (2014), reported that daughters born to older dams produced less milk.…”

The purpose of the study was to asses the effect of calving season and dams' parity on milk yield and gestation length of dairy cows. We examined 93 animals of Slovak spotted breed from the farm located in western Slovakia (Lower Váh region), in years 2014-2017. The herds' average 305-d milk yield was 8,133 ±1,380 kg. The calving season was divided into four categories: spring (March to May), summer (June to August), autumn (September to November) and winter (December to February). The factor of dams parity was divided into 4 groups: 1 st parity cows, 2 nd-3 rd parity cows, 4 th and higher parity cows. Calving season affected significantly milk yield of dairy cows (P <0.01). The highest 305-d milk production was oberved in winter calvings (8,942 ±218 kg) and the lowest in spring calvings (7,377 ±287 kg). The gestation length was not signifficantly altered by calving season (P >0.32). Dams' parity was not significantly affected by 305-d milk yield (P >0.22). Nevertheless, the animals on the 4 th and higher lactation were numerically more productive (8,481 ±259 kg) compared to the dairy cows on their 1 st , 2 nd-3 rd lactation (8,123 ±264 kg; 7,884 ±223 kg; resp.). The dams' parity significantly affected gestation length (P <0.02), with the shortest gestation length in 1 st parity dams (278 ±2 days) and the longest gestation in 2 nd-3 rd parity dams (284 ±1 days).To sum up, our results suggest significant role of calving season in relation to milk yield and significant effect of dams' parity on gestation length.

“…Regarding the teats, in other studies, a significant correlation between the number and period of lactation and different measurements such as teat height above the ground, teat length and teat diameter could be shown. For instance, Ceyhan et al [45] found a decreased clearance of front and rear teats from the ground in cows in their second lactation compared to first lactating cows. In contrast, teat diameter and teat length increased.…”

Effects of Suckling on the Udder Health of Foster Cows

et al. 2021

In a foster cow system, one or more calves are reared by a foster cow. With regard to the growing rejection towards the early separation of cow and calf after calving, such alternative rearing methods with prolonged cow–calf contact are coming more into focus. Nevertheless, there is a lack of recent studies investigating the effects of suckling multiple calves on the udder health of a foster cow. The present study aimed to initially describe the status and development of the udder condition and the microbial colonisation during the foster period. Thereby, the objectives were to determine whether suckling multiple calves was associated with an increase in intramammary infections (IMI) and a deterioration of udder constitution. A total of 99 Holstein Friesian foster cows from a large organic dairy farm in eastern Germany were included in this pilot study. Each foster cow was suckled by 3–4 calves and not additionally milked. Quarter milk samples were taken for cytomicrobiological examination at the beginning and end of the approximately 3.5 months suckling period. At the same time, the udders of 91 of these foster cows were clinically examined by visual assessment and manual palpation. In both the first and second examination (E1 and E2, respectively), Corynebacterium ssp. and non-aureus staphylococci (NaS) constituted the most frequently detected pathogen species in the 385 examined udder quarters. Classifying the quarters into mastitis categories was significantly different between the two examinations (p = 0.001). The number of quarters considered as healthy increased from E1 to E2 by 8.5%. At the same time, the number of quarters with mastitis decreased by 2.6%, the number of quarters with non-specific mastitis by 11.4% and the number of quarters with a latent infection increased by 5.4%. In total, 69.4% of the 121 infected udder quarters in E1 were bacteriologically cured in E2. A cytological cure was achieved in 28.1% of the 385 quarters. Both the bacteriological and cytological cure rate were spontaneous. A new infection occurred in 23.1% of the 385 examined udder quarters and was mainly attributable to infections with Corynebacterium spp. and NaS. During the suckling period, mainly new infections occurred and amounted to 73% in relation to presumed persistent infections (18.9%). The new infections were mainly attributable to infections with Corynebacterium spp. and NaS. Pasteurella spp. were also found in high percentages. A total of 10.1% of the quarters showed an increase in somatic cell count (SCC) above the threshold of 100,000 cells/mL from E1 to E2, indicating a new subclinical mastitis. Regarding udder condition, significant changes during the foster period were an increase in udder skin and teat lesions, a decrease in udder oedema, an increased amount of udder quarters with a consistency considered as normal and an increase in the number of udders showing no sign of udder cleft dermatitis. Moreover, teat length, circumference, and diameter increased significantly (p < 0.05). In conclusion, there is a possibility that suckling multiple calves improves udder health in terms of mastitis but leads to an increased pathogen transmission at the same time, resulting in an increase in latent infections. Additionally, pathogens as Pasteurella spp., which are usually located in the upper respiratory system, could be detected in the mammary gland. The changes concerning the udder condition were manifold. However, it has not yet been conclusively clarified whether all these changes are exclusively due to calf suckling. Further investigations with a non-suckled control group are required.
