Abstract
The quality of cow’s milk and the spread of mastitis greatly depend on the level of udder hygiene. Our author’s research was conducted to evaluate the effects of Forticept® Udder Wash and Forticept® Udder Forte, used before and after milking, on the treatment and prevention of subclinical mastitis and hyperkeratosis of cows’ udders. A total of 6880 milk samples were taken from 430 cows, 3-4 years old, 470-490 kg weight, at 60 ± 15 days of lactation. The therapeutic efficacy coefficient (EC) of Forticept® polymers based on benzetonium and benzalkonium chloride, against the subclinical form of mastitis was 73.8% compared to iodine-containing agents; preventive EC - 32.4%. Dipping hygiene of the udder using Forticept® on the 30th day reduced the number of 1-3 stage teat hyperkeratosis cases from 78.8% to 41.3%. Also, during this period, a significant (P<0.05) improvement in the chemical parameters of the milk was observed - an increase in fat (up to 3.94 ± 0.08%), protein (3.35 ± 0.07%), casein (3.15 ± 0.09%) and dry matter (14.91 ± 0.28%). After using Forticept®, the total bacteria count (TBC) of the milk decreased to 3×105 CFU/cm3, and the somatic cell count (SCC) - to 130 thousand/cm3 (P<0.05). Test day milk yield (TDMY) increased by 1.15% due to efficient dipping with Forticept® (P<0.05).
Highlights
In the experiment, udder dipping with Forticept® Udder Wash and Forticept® Udder Forte cured subclinical mastitis form (SMF) in 59.6% of cases already on the 20th day of use (Fig. 1), therapeutic efficacy coefficient (EC) = 73.8% compared to the iodine-containing agents in the control
After 30 days of Forticept® administration to healthy cows, 96.4% of milk samples showed no signs of SMF, with prophylactic EC = 32.4%
The dipping hygiene of the udder on the 30th day using Forticept® reduced the number of teats affected by hyperkeratosis of varying severity from the initial 78.8 to 41.3% (Fig. 2)
Summary
It is greatly dependent on the level of breeding work with the herd, the composition and nutritional value of rations, the hygiene of housing, and the status of cows’ health (Yurchenko and BIHUN, 2012). In the case of subclinical mastitis, the milk most often has no visible changes. After filtering such milk, tiny particles of coagulated protein can be detected in it (Murphy et al, 2016). The fat content and density of this milk are reduced. Reduced resistance to heat leads to spontaneous coagulation of mastitis milk during its heat treatment (Pyz-Łukasik et al, 2015)
