The study involved the use of Echinapur preparation, containing Echinacea purpurea extract, to promote milk lactoferrin secretion, and – as a result of its antibacterial properties – to reduce inflammatory changes in the goat’s mammary gland. Ten goats with the highest somatic cell count (SCC) of milk were selected from the flock and treated for two weeks with Echinapur. In order to estimate treatment effectiveness, milk was examined for lactoferrin (Lf) concentration, SCC, bacteria counts as colony forming units (CFU) and yield and gross composition of milk, before and at the end of treatment, and then 2 and 4 weeks later. Milk Lf content was determined using the RP-HPLC technique,and milk SCC, CFU and chemical composition were determined instrumentally. Treatment resulted in a transient (P<0.01) decrease of milk protein content below the initial level, compensated by a gradual increase of milk yield (24% over the pre-treatment value). A substantial increase in milk Lf content, with a maximum response (P<0.01) at 2 weeks after the end of treatment, was accompanied by a gradual reduction (P<0.01) in SCC and CFU compared to initial values. This is the first report showing the feasibility of promoting Lf secretion in order to reduce inflammatory changes in the goat mammary gland.

Badano zastosowanie preparatu Echinapur zawierającego ekstrakt jeżówki purpurowej (Echinacea purpurea) do pobudzania sekrecji laktoferyny (Lf) w mleku i – w wyniku jej antybakteryjnych właściwości – zredukowania zmian zapalnych w gruczole mlekowym kóz. Ze stada wybrano 10 kóz z najwyższą liczbą komórek somatycznych (SCC) w mleku, którym przez 2 tygodnie podawano Echinapur.Jedno zwierzę wycofano z racji klinicznego mastitis i leczenia antybiotykiem. Dla oceny efektywności zastosowanego preparatu określano w mleku SCC, ogólną liczbę bakterii (CFU), poziom Lf oraz wydajność i podstawowy skład mleka przed i po zakończeniu podawania preparatu oraz po upływie dalszych 2 i 4 tygodni. Zawartość Lf w mleku oznaczano metodą RP-HPLC a SCC i CFU metodami instrumentalnymi. Stwierdzono przejściowe (P<0,01) obniżenie zawartości białka w mleku poniżej wartości wyjściowych, rekompensowane przez stopniowy wzrost wydajności mleka (24% powyżej poziomu początkowego).Nastąpiło znaczące zwiększenie zawartości Lf w mleku, z maksymalną reakcją (P<0,01) po 2 tygodniach od zakończenia podawania preparatu oraz stopniowe zmniejszenie (P<0,01) SCC i CFU w stosunku do wartości wyjściowych. Jest to pierwsze doniesienie o możliwości stymulowania sekrecji Lf w mleku I ograniczenia w ten sposób zmian zapalnych w gruczole mlekowym kóz.
