The fluctuations in the plasma levels of several bone markers were investigated in newborn calves. Experiment 1 monitored the postnatal changes in the plasma levels of tartrate-resistant acid phosphatase isoform 5b (TRAP5b), total alkaline phosphatase (t-ALP) and bone-specific alkaline phosphatase (BAP) in four calves. These markers increased significantly from 9−20 hr after the first colostrum-suckling compared with the values immediately after birth. Experiment 2 evaluated changes in the plasma TRAP5b, t-ALP, BAP and type I collagen cross-linked N-telopeptide (NTx) levels within 2 days post-birth in five calves with successful passive immunization via colostrum (non-deficient group) and five others with poor colostrum intake (deficient group). The non-deficient group had significantly higher plasma levels of the four parameters around 12 hr of life compared with the deficient group. The results suggest that the increase in plasma bone markers in calves in the first day of life is related to the colostrum intake.  相似文献   

Studies on immunoglobulins and trypsin inhibitor in colostrum and milk from sows and in serum of their piglets.     

P T Jensen  K B Pedersen 《Acta veterinaria Scandinavica》1979,20(1):60-72

The concentrations of IgG, IgM, IgA and the specific sow colostrum trypsin inhibitor (SCTI) were measured by radial immunodiffusion in colostrum and milk samples from sows and in serum samples from their offspring during the suckling period. A clear time dependence was found for all the measured variates in both whey and serum. Statistically significant positive correlations were found between, on the one hand, concentrations of IgG and IgA, but not IgM, in sera from 39 suckling piglets 1 and 3 days old, and, on the other hand, concentrations of the same immunoglobulins and of the trypsin inhibitor in maternal colostrum (n = 7). Multiple regression analyses showed that at day 1 and day 3 the levels of both IgG and IgA in serum samples from the suckling piglets were positively influenced by both the SCTI and the IgG or IgA contents in maternal colostrum.  相似文献   

The effect of colostrum ingestion during the first 24 hours of life on early postnatal development of piglet immune systems          下载免费PDF全文

It has been suggested that colostrum is important not only for direct protection from pathogens but also for proper development of immune systems in piglets. In this study, we focused on the effect of colostrum ingestion during the first 24 h of life on early postnatal development of piglet immune systems. Thirty‐six piglets from five litters were divided into colostrum‐fed (CoF) and colostrum‐deprived (CoD) groups. The former group was allowed to suckle normally while formula milk was fed to the latter group during the first 24 h of life. At the weaning period, the concentrations of fecal immunoglobulin (Ig) A and plasma IgG as well as the number of blood leukocyte subsets were analyzed. Fecal IgA and plasma IgG concentrations in the CoF group were more than twice as high as those in the CoD group (P < 0.01). In addition, the number of blood B cells was significantly higher in the CoF group than that in the CoD group (P < 0.05). This study demonstrates that colostrum ingestion during the first 24 h plays a significant role in early postnatal development of both mucosal and systemic immunity of piglets.  相似文献   

The Effect of Fermented Vegetable Soybean Straw on Reproductive Performances,Colostrum Quality and Digestion in Adult Female Goat     

ZHU Yong  YU Si-jia  BAO Jian  XU Jian-xiong 《中国畜牧兽医》2017,44(1):100-105

The experiment was conducted to study the effects of fermented vegetable soybean straw (FSBS) on reproductive performances, colostrum quality and digestion in adult female goats.A total of 16 Chongming White pregnant goats with similar parity were randomly divided into 4 groups and were fed granular TMR with 0 (control group),17.5% (group A),35.0%(group B) and 52.5%(group C) FSBS, respectively. The results showed that:Compared with the control group and group A, the apparent digestibility of DM, CP, CF and OM of 30 days after delivery in group C significantly increased (P<0.05).The contents of urea nitrogen among 4 groups had significant differences (P<0.05)and group C was the lowest;Lambing birth weight,weaning weight,the content of milk fat, protein, lactose, TS and SNF in group C were significantly higher than that in control group (P<0.05).In conclusion, FSBS could improve the reproductive performance and nutrient digestibility of adult female goats,its appropriate level in TMR should be 52.5%.  相似文献

LIU Xiaofei  GAO Xuejun  YAO Yonghao  ZHOU Shenghua 《东北农业大学学报(英文版)》2008,15(2)

sIgA in bovine colostrum was purified by ultrafiltration and enzymolysis methods in this experiment, and the prepared substance was detected by Western Blot. The purity and yield were up to 73.6% and 65.2%, respectively. This convenient technique offers helpful exploration for production of bovine colostrum sIgA.  相似文献

Relationship between parity and mineral status in dairy cows during the periparturient period     

Shin-ichi KUME  Kazuhisa NONAKA  Tomoko OSHITA 《Animal Science Journal》2003,74(3):211-215

Data from 65 cows were collected to clarify the relationship between parity and mineral status in Holstein cows during the periparturient period. Milk fever occurred in a second‐ and a fourth‐lactation cow at parturition. Bodyweight of cows decreased immediately after parturition, and the decreased weights of cows from 1 to 6 days after parturition ranged from 11 to 27 kg. Milk yield of multiparous cows was higher than that of primiparous cows, but Ca and P concentrations in colostrum were not affected by the parity. Plasma glucose of primiparous cows was higher than that of multiparous cows, and plasma nonesterified fatty acids of fourth‐and‐more‐lactation cows at parturition was highest. Plasma Ca concentration of cows at parturition decreased with advancing parity, and plasma inorganic P concentration of third‐and‐more‐lactation cows was lowest at parturition. Plasma parathyroid hormone of fourth‐and‐more‐lactation cows at parturition was highest, but plasma hydroxyproline and alkaline phosphatase was lowest. These results suggest that the large transfer of Ca and P to colostrum is a factor in the development of milk fever in third‐and‐more‐lactation cows.  相似文献   

Effects of dietary soluble or insoluble fiber intake in late gestation on litter performance,milk composition,immune function,and redox status of sows around parturition

The objective of this study was to investigate the effects of dietary soluble fiber (SF) or insoluble fiber (ISF) intake in late gestation on litter performance, milk composition, immune function, and redox status of sows around parturition. A total of 60 Yorkshire sows were randomly assigned into three dietary treatments: normal level of dietary fiber (CON, 16.16% dietary fiber with 1.78% soluble fiber and 14.38% insoluble fiber), high insoluble fiber (ISF, 30.12% dietary fiber with 2.97% soluble fiber and 27.15% insoluble fiber), and high soluble fiber (SF, 30.15% dietary fiber with 4.57% soluble fiber and 25.58% insoluble fiber). Digestible energy and crude protein intake were comparable among treatments via adjusting feed intake from day 90 of gestation to parturition. After parturition, all sows were fed the same lactation diet. Results showed that litter performance of sows was not markedly affected by maternal fiber intake. However, sows fed ISF or SF diet had increased concentration of plasma mmunoglobulin G at day 107 (P < 0.05) and parturition (P < 0.01), and the SF diet had a tendency to increase fat content in both colostrum and milk relative to the CON diet. Furthermore, sows fed ISF diet had increased glutathione peroxidase activity (P < 0.05) at day 107, but decreased the plasma level of malondialdehyde at parturition (P < 0.05). High maternal SF intake tended to decrease the number of weaned piglets due to the increased preweaning mortality, as compared with sows fed the ISF diet. In conclusion, high fiber intake in late gestation may improve immune function and redox status, but differentially influenced the milk composition and preweaning mortality.  相似文献
