استهدفت هذه الدراسة تقييم فعالية ثلاثة أنواع من المعقمات التجارية و هي ماءات الأمونيوم (Ammonium hydroxide) و الفينول (pheno) رباعيات الأمونيوم (Quaternary ammonium) بتراكيز 5%, 10%, 20 %, و ذلك من حيث تأثيرها على الكيسات البيضية غير المتبوغة للإيميرية ستيدي (Eimeria Stiedae) (Unsporulated E. Stiedae oocysts) و التي تصيب الكبد و الأقنية الصفراوية عند الأرانب و تتسبب بالتهاب و تضخم في الكبد و المرارة و القناة صفراوية المعدية, و آفات تنكزية بيضاء بالكبد, بالإضافة إلى ماسبق دُرسَت أيضاً بعض التأثيرات البيئية لعوامل تتضمن درجة الحرارة و رقم الباهاء (Ph) و وجود المادّة العضوية.
We have been evaluating the effectiveness of three types of commercial disinfectants include ammonium hydroxide, and phenol and ammonium Quaternary in concentrations of 5%, 10%, 20% of each, to the effect on the non sporulated cysts ovales for Coccidia type stiedae, which affects the liver and bile ducts in the rabbit, and cause inflammation and hyperplasia in liver, gallbladder and biliary canal infectious, and necrotic lesions with white color in the liver tissue, in addition to the foregoing, also examined some of the environmental effects of factors, including temperature , pH and presence of organic matter.

The aim of this experiment to study some of the blood parameters
associated with hepatic coccidiosis induced by Eimeria stiedae in
rabbits, and compare it with the blood changes when infected
rabbits treating with the toltrazuril compound.
21 rab
bit-old (4-8 weeks) were Used for this experiment of both
sexes and were divided into three groups (seven rabbits in each
group): Group of natural witness, and a Group of patient witness,
where the infection caused by challenge dose of about forty
thousand mature oocyst for each rabbit by mouth, and a treatment
group that has been given the same previous challenge dose.
A study was conducted to investigate the protective and therapeutic
effects of Ecballium elaterium juice against experimental infection
with Eimeria stiedae in rabbits. Thirty- two rabbits were divided
into four groups (eight rabbits in each group
) : healthy control group
(HC); challenged – Ecballium elaterium –protected group (CEEP)
which received a daily dose of (45) μl\kg body weight Ecballium
elaterium juice intra-peritoneal for five days before challenged with
E. stiedae ; challenged – Ecballium elaterium –treated group
(CEET) which received a daily dose of (45)μl\kg body weight
Ecballium elaterium juice intra-peritoneal for five days after
challenged with of E .stiedae and infected group (IC).The challenge
dose was 40000 sporulated E. stiedae oocyst per rabbits.

For studying the effect of cadmium sulphate on some physiological components
of blood in male white rabbits. we used (12) animals divided in to two groups (6 animals
per group).the experimental one became aqueous cadmium sulphate (5 mg/kg) orally,
while the control became water for 28 days (4 weeks).
We reported significant decrease (p<0.01) in the count of red blood cells ,
Hematocrit values and Hemoglobin concentration.
Two experiments were conducted to test the effect of pelleted foods on the
growth of California white rabbit.
٣٦ weaned rabbits, used in the first experiment, were distributed randomly
and equally inside ٦ boxes. Pelleted and ground foods having t
he same
composition were offered simultanously to be eaten ad libitum for ٢٥ days.
Another ٢٤ weened rabbits, used in the second experiment, were also divided
randomly and equally into two groups. Pelleted and ground foods were offered
to the first and second group respictively to be eaten ad libitum for ٢٥ days.
