“…Until now, research on the influence of parity on the SCC in dairy donkeys is scare. However, previous studies on the dairy cows had reported that the parity was associated with variation in SCC (46,47). In contrast to our results in donkeys, Brolund (48) reported that the mean SCC for the Swedish Red and White breed increased from 28 × 10 3 cells/ml for parity 1 of cows to 72 × 10 3 cells/ml for parity 4 of cows.…”

IntroductionThe number of the large-scale donkey breeding farms in China has increased dramatically. However, information regarding the situation of a Chinese donkey population under large-scale donkey breeding farms is limited.MethodsThis survey report was conducted using questionnaires online to investigate the current situation of the donkey original breeding farms in China, in terms of donkey stock, local breeds, reproductive parameters, growth and lactation performance, and future perspectives. China has developed the donkey reserve system based on national, provincial and non-governmental (self-own) donkey original breeding farms.ResultsIn the present study, a total of 38 donkey original breeding farms concentrated in Northern of China were studied, and 52% of them keep their donkeys with a stocking density of 100–500 donkeys. China is rich in various local donkey breeds, and 16 local donkey breeds including large-sized, medium-sized and small-sized breeds were collected in our survey. Dezhou donkey are prevalent with a percentage of more than 57% of the total donkeys, while the Cullen donkeys belong to small-sized donkey breeds are scare. The reproductive efficiency and donkey productivity were different across donkey farms, indicating potential differences in management and breeding practices between different donkey original breeding farms. The artificial insemination has been performed in these donkey farms with an average proportion of 73%. Regarding the donkey productivity, the national and provincial donkey original breeding farms showed a higher birthweight and fat content in donkey milk than self-own farms. Furthermore, our results indicate that the donkey breeds with different body size also have important influence on the reproduction parameters and donkey productivity, with the large-sized donkeys had better performance compared to the small-sized donkeys.DiscussionIn summary, our survey provided valuable baseline information on the situation of donkey population dynamics in the donkey original breeding farms. However, further study is required in the future to investigate the factors such as donkey health care, management and nutrition during breeding, fattening and lactation that influence donkey productivity under large-scale farm systems.

“…The effects of other fixed factors, including parity, stage of lactation and month of calving, on the milk composition were comparable with previous studies 25–28 . Nevertheless, the effects of these factors on the milk composition were not the specific focus of the present study and were previously discussed in research conducted within the same region 25–28 …”

[25][26][27][28] Finally, the relationships between SCC and MIR spectral wavenumbers were demonstrated. The first region (wavenumbers 925-1582 cm −1 ) is called the 'fingerprint region' because it contains some important chemical bonds (C-H, aromatic C=C, C-O and N-O) in milk and is associated with the absorbance for milk compositions such as protein, lactose and urea.…”

“…The SCS exhibited a weak correlation with total solids, and the fixed factor of SCC class had no significant effect on total solids, which was supported by Yang et al 23 and Guan et al 19 The milk urea concentration showed a very weak correlation with the SCS, and the least squares means were not significantly different in classes 1 and 2 and were significantly higher than those in class 3, which was in accordance with the studies of Benedet et al 21 and Bobbo et al 24 The effects of other fixed factors, including parity, stage of lactation and month of calving, on the milk composition were comparable with previous studies. [25][26][27][28] Nevertheless, the effects of these factors on the milk composition were not the specific focus of the present study and were previously discussed in research conducted within the same region.

BackgroundMilk produced by dairy cows is a complex combination of many components, but the effect of mastitis has only been investigated for a few of these components. Milk mid‐infrared (MIR) spectra can reflect the global composition of milk, and this study aimed to detect the relationships between milk MIR spectral wavenumbers and milk somatic cell count (SCC)—a sensitive biomarker for mastitis.MethodsPearson correlation analysis was used to calculate the correlation coefficient between somatic count score (SCS) and spectral wavenumbers. A general linear mixed model was applied to investigate the effect of three different classes of SCC (low, middle and high) on spectral wavenumbers.ResultsThe mean correlation coefficient between the ‘fingerprint region’ (wavenumbers 925–1582 cm–1) and the SCS was higher than that for other regions of the MIR spectrum, and the specific wavenumber with the strongest correlation with the SCS was within the ‘fingerprint region’. SCC class had a significant (p < 0.05) effect on 639 spectral wavenumbers. In particular, some spectral wavenumbers within the ‘fingerprint region’ were highly affected by the SCC class.LimitationThe data were collected from only one province in China, so the generalisability of the findings may be limited.ConclusionSCC had close relationships with milk spectral wavenumbers related to important milk components or chemical bonds.

“…Another limitation of the study is the lack of detailed information about individual cow status, such as a short time record of the number of SCC (incidence of subclinical mastitis), udder condition, genetic background, and difficulty adjusting the parity and time of sample collection for the cows. Confounding factors associated with milk production properties such as parity, age, calving interval, and herd were considered to affect milk production ability relatively [ 51 , 52 ]. In this study, only the parity was included, but the other confounding factor might have needed to be noticed.…”
