Effect of Extending Voluntary Waiting Period on Health of Holstein Friesian Dairy Cows

The aim of this of this experimental study to investigate the effect of 3 voluntary waiting periods (VWP) on health of dairy cows. A total of 100 lactations of 100 Holstein Friesian cows with high milk production (average 9.442 ± 620 kg) were randomly (based on the ear tags digits of cows) distributed to 1 to 3 experimental groups with VWP of 50 (VWPG50;n = 32), 100 (VWPG100;n = 34) or 150 days (VWPG150;n = 34). Observations relating to diseases of the cows were made by the farm veterinarian and research personnel. Were defined eight disease: puerperal fever, retained fetal membranes, displaced abomasum, metritis, clinical ketosis, clinical mastitis, ovarian cysts, and claw diseases. The experimental days (ED) were from 4 days in milk (DIM) to 100 days after the next calving. The experiment was managed at Dairy Research Farm ?imnic-Craiova January 2018 to December 2022. A clear set of clinical signs were used to define a case at the diseases without the need for laboratory confirmation. Values of Lactational incidence risk (LIR) median postpartum days at diagnosis and pairwise comparison of proportion between VWPs were calculated. LIR for puerperal fiver, retained fetal membranes, displaced abomasum, clinical ketosis, clinical mastitis, ovarian cysts and claw disease were 4;5;2;8;8;and 4% respectively. Numerically, cows with VWP of 100 and150 days had more disease cases compared with VWP of 50 days. The differences between experimental groups of cows regarding proportions of cows with disease cases were not statistically significant. Any of the eight disorders reported in this study was analyzed independently to other health problems. For all enrolled cows (n = 100) VWP was extended until 100 or 150 days postpartum with no effect on the lactational incidence risk for the eight disorders analyzed.

Treatment of 62 Patients with Postpartum Lactation Disorder by Acupuncture

Sixty two patients with postpartum lactation disorder were treated by needling Neiguan （PC 6）, Zusanli（ST 36）, Rugen（ST 18） and Jianzhen（SI 9）, and moxibustion at Danzhong（CV 17）. After 7 treatments, 30 puerperae were vigorous and could lactate 400 mL every day, 26 puerperae could lactate 250 mL every day, and need other milk to feed the children, and 6 puerperae had no improvement in lactation, and lactate a little as pressing the breasts.

Research Advance on Tuina and Postpartum Milk Secretion

Objective： To analyze the relevant literature regarding the effect of tuina on postpartum milk secretion and thus summarize the clinical rules on tuina for lactation disorder. Method： Investigate the relationship between tuina and postpartum milk secretion for four aspects, including the initial time of lactation, level of serum prolactin, volume of lactation, and Chinese medicine＇s understanding of tuina on milk secretion. Result and Conclusion： Tuina on breasts after childbirth can speed and promote lactation. This has been proved by clinical practice over the past hundreds of years, along with modem laboratory and scientific research. This method, therefore, is of great significance in obstetrical nursing.

Study on Clinical Efficacy of Needling Danzhong(CV 17) in Treating Postpartum Hypogalactia

Objective： To investigate the clinical efficacy of needling Danzhong（CV 17） in the treatment of postpartum hypogalactia and provide clinical evidence for indications of the point. Methods： A multi-centre single-blind randomized controlled trial was carried out. Two hundred and seventy-six puerperal women with postpartum hypogalactia were randomly allocated into acupuncture group and herb group, and respectively treated for three consecutive days. The degree of mammary fullness, the amount of milk secreted, prolacfin, baby weight, the frequency and volume of artificial feeding, the number of infant urination events, and the duration of baby crying were observed. The clinical curative effects on postpartum hypogalactia were compared. Results： Hypogalactia was effectively treated in both acupuncture and herb groups. There were statistically significant differences in degree of mammary fullness, amount of milk secreted, baby weight, the frequency and amount of artificial feeding, and the number of infant urination events between pretreatment and post-treatment, but no difference between the two groups. There was no significant difference in prolactin in the acupuncture group and there was a difference in prolactin in the herb group between pretreatment and posttreatment. Conclusion： Needling Danzhong（CV 17） can effectively promote lactation.
