Individual identification of dairy cows based on deep learning and feature fusion
AbstractIndividual identification of dairy cows is one of the most important prerequisites for an intelligent dairy farming. Herein, a new method of individual identification of dairy cows based on the fusion of deep and shallow features of dairy cow's trunk image is proposed. Our aim is to obtain low-cost, touch-free, and high-accuracy individual identification of dairy cows. First, the model of VGG-16 is improved. Second, the multiple overlapping pooling layer in the improved VGG-16 model is used as a feature extractor to extract the features of dairy cow's trunk image, and the global average pooling (GAP) layer was used...

Evaluation of post ‐colostrum ingestion changes in the protein composition of peripheral blood of newborn piglets: A pilot study
AbstractPutatively, colostral proteins are partly absorbed and transferred to blood circulation in newborn piglets, which suggests that colostrum ingestion alters the protein composition of their blood. Here, we conducted a pilot study to estimate the changes in the protein composition of piglet blood. Plasma collected from piglets pre- and post-ingestion of colostrum (PreC and PostC) was analyzed by shotgun proteomics. Proteins in colostrum were also analyzed. We identified 393 and 427 proteins in PreC and PostC plasma, respectively, and 596 colostral proteins. Whereas 202 unique proteins were identified in PostC, PreC an...

Anti ‐Müllerian hormone stimulates expression of the collagen‐specific chaperone 47‐kDa heat shock protein in bovine uterine epithelial cells
AbstractUterine collagen is the most abundant component of the uterine extracellular matrix and plays a critical role in pregnancy. The 47-kDa heat shock protein (HSP47) is the sole collagen-specific molecular chaperone. We investigated the mechanisms regulating the expression of HSP47 in the uterus by assessing the effect of anti-M üllerian hormone (AMH) stimulation on HSP47 expression in cultured bovine uterine epithelial cells. AMH receptor type 2 (AMHR2), AMH, and HSP47 expression was assessed by fluorescence immunocytochemistry in uterine epithelial layers of the uteri of Japanese Black cows. The effect of AMH on HSP...

Changes in immunoglobulin A and immunoglobulin G concentrations in the saliva of Japanese Black beef cows during calving: A pilot study
This study evaluated changes in salivary IgA and Immunoglobulin G (IgG) concentrations in Japanese Black cows (n = 16) during calving. Individual saliva samples were collected −2, 0, and 2 weeks postpartum. Immunoglobulin concentrations differed significantly among weeks (P < 0.05), but the effect of parity and week × parity was insignificant. Salivary IgA concentrations decreased drastically (P < 0.05) after calving compared with those at −2 weeks postpartum and remained low until 2 weeks postpartum. The salivary IgG concentrations decreased gradually during peripartum and differed at −2 ...

Metabonomic identification of serum biomarkers related to heat stress tolerance of sheep
This study was to compare the serum metabolomes of Hu sheep and Dorper sheep and identify potential biomarkers related to heat stress. The results revealed that the respiratory rate, heart rate, and rectal temperature of Dorper sheep were significantly higher than those of Hu sheep. Compared to Dorper sheep, the serum activities of total antioxidant capacity and glutathione peroxidase in Hu sheep were significantly higher, while the concentration of malondialdehyde was lower. Metabolomics analysis identified 107 differential serum metabolites. The pathways enriched from the altered serum metabolites between the two breeds ...

Sodium butyrate administration modulates the ruminal villus height, inflammation ‐related gene expression, and plasma hormones concentration in dry cows fed a high‐fiber diet
The objectives of this study were to evaluate the effects of sodium butyrate on the ruminal villus morphology, mRNA expression associated with nutrient metabolism and inflammation in the ruminal epithelium, and plasma concentrations of metabolites and hormones in non-lactating cows fed a high-fiber diet. Four Holstein cows with a rumen cannula were assigned to two treatments in a crossover design. The treatments were ruminal administration of sodium butyrate premix or control premix before feeding to cows fed the same total mixed ration mainly composed of glass silage once a day. Sodium butyrate was provided at a butyrate ...
