Abstract

Impact of defaunation (removal of protozoa from the rumen) on animal health and productivity is still controversial. This study quantified the effects of defaunation intervals using two defaunating agents; sodium lauryl sulfate (SLS) and dioctyl sodium sulfosuccinate (DSS), on serum and milk profiles in lactating goats. Ten apparently healthy female Egyptian native breed lactating goats were assigned into two experimental groups. The administration of both defaunating agents was carried out daily for the first three days of the experiment then once weekly for three consecutive weeks. The research samples were collected before defaunation, 7, 14, and 21 days post defaunation. Milk parameters were determined using milk lactometer and selected serum parameters were measured using specific kits. Generally, defaunation resulted in a significant decrease in milk fat, solid not fat, and salt%, with significant increment in serum calcium (Ca) and inorganic phosphorous (P). Serum Ca and albumin decreased significantly at 14 days than 21 days post defaunation. Serum inorganic P decreased significantly due to DSS than SLS and at 14 days than 7 days post defaunation. Milk profile was significantly undesirably influenced by using DSS more than SLS, and at time point of 14 days post defaunation. Defaunation using DSS or SLS for 14–21 days has a dramatically negative influence on milk profile. It is recommended not to use DSS for treatment of rumen bloat or indigestion in dairy goats.
