The objective of this study was to evaluate the influence of blood and milk zinc concentration on somatic cell count, milk production and occurrence of subclinical mastitis cases. The study was performed on thirty Holstein cows approximate same body weight, ages 3 to 5 years, with equally milk production. Blood samples were taken after the morning milking from the caudal vein and milk from all four quarters was taken during morning milking. All samples of blood and milk were taken to determined zinc, using inductively coupled plasma mass spectrometry. 37.67% (11/30) cows have blood serum zinc concentration below 7?mol/l, and 63.33% or 19/30 cows have blood serum zinc concentration higher then 13?mol/l. Also 30% (9/30) cows have somatic cell count lower then 400.000/ml which indicate absence of subclinical mastitis, but 70% (21/30) cows have somatic cell count higher then 400.000/ml which indicate subclinical mastitis. According to all results in this research, zinc has very important influence on reducing subclinical mastitis and somatic cell count in milk of dairy cows.

Background Any dairy herd that continually has a somatic cell count (SCC) above 200,000 cells/ml has an indication of mammary gland inflammation (mastitis). Routine use of antibiotics to prevent mastitis is prohibited by organic farming regulations. This limitation has lead researchers to focus on cows natural defense mechanisms [1]. Calcarea carbonica derivative complex (M8) is a complex high diluted medication comprised of comprised of Calcarea carbonica 16x, Aconitum napellus 20x, Arsenicum album 18x, Asa foetida 20x, Conium maculatum 17x, Ipecacuanha 13x, Phosphorus 20x, Rhus toxicodendron 17x, Silicea 20x, Sulphur 24x, and Thuya occidentalis 19x. Dilution procedures have followed standard methodology described at the Brazilian Homeopathic Pharmacopoeia. This medication has enhanced immune system responses both in vitro and in vivo in a murine model [2]. Aims In the present study, we investigate the response of dairy cows after M8 treatment. Methodology The study was performed as a randomized, observer double-blinded and placebo-controlled trial, with a stratified design, using lactation number and SCC as stratification factors. The study sample consisted of 42 lactating dairy cows (Holstein) in one high producing dairy herd with 52 cows in milk in southern Brazil, divided into two experimental groups (n=21). Exclusion criteria were cows with clinical mastitis or receiving any other medical treatment. Pre- and post-milking teat disinfection was practiced in the herd. All cows were clinically examined, with udder and milk samples being appraised according to Rosenberger (1990) [3]. During 3 months one group received daily M8 treatment, the other placebo. Oral administration of 5 ml/day/cow was performed using an automatic dosage dispenser. Monthly, milk production, SCC, fat and total protein content were carefully recorded for each animal by an official milk recording program. SCC were log transformed for analysis. ANOVA and Tukey test were used to compare the averages. The Bartlett´s test was used for homogeneity of variance evaluation. Results There were no significant differences (P=0.435) among the groups in the initial evaluation (Values of SCC x103 : Placebo 67,37±80,48; Treatment 359,39±677,02). After 3 months, the M8 treated group showed a decrease (134,00±178,76 P= 0.047) in SCC when compared with control group (391,71±686,60). Fat and protein did not differ between groups and time analysed. Milk production decreased in the placebo group during time (Before: 34,97±6,69kg; After:28,69±4,33kg), whereas the treatment group did not change total amount (Before: 28,7±6,54kg; After: 26,39±5,73kg; P > 0.05). Conclusions These results indicate that the M8 influenced positively SCC and suggest that it may be considered as a possible tool to promote bovine mastitis prophylaxis.

SummaryWhen six cows were milked every 4 h over 48 h the average milk yield per cow increased by 1O·7% for the last 24 h period compared with the previous 5 d. Milk composition was similar to pre-experimental values although fat content was 0·5% lower in the last 24 h. The somatic cell count rose to twice the pre-experimental value over the first 24 h but was not significantly different by the second 24 h. It appears that cows responded quickly to an increased frequency of milking and milk of an acceptable composition was produced. This has implications for management of milk production where quotas are in operation and for robotic milking systems.
