Abstract :
Abstract - In considering the interaction between
microorganisms and insecticides, some certain effects may
become significant. These effects involve the potential
inhibition or possible germicidal action of insecticides on
rumen microbes. Proper functioning of these microorganisms is
essential, since they supply approximately 50 to 70% of the
energy requirements of ruminants. Any deleterious influence,
even of a temporary nature, could have a profound effect on
the bacterial activity and subsequently upon the host animal.
So a study to investigate the effects of different levels (0, 0.7, 2.8
and 5.6 mg) of phosalone as an insecticide with different levels
of calcium bentonite (0 and 100 mg) on in vitro dry matter
disappearance was carried out in the farm of animal science in
Ferdowsi University of Mashhad, Iran in 2012. The study
indicated that all the levels of phosalone had not any significant
effect on in situ dry matter disappearance (ISDMD),only the
effect of phosalone was significant after 24h incubation
(p < 0.05). There was a significant effect (P < 0.01) for calcium
bentonite for effective dry matter digestibility (EDMD), the
rapidly soluble fraction (a) and the potentially degradable
fraction (b). In this experiment calcium bentonite is tested as
toxin binder for decreasing the probably deleterious effects of
phosalone on rumen degradability of dry matter.
