Solution: The uterine glands secrete 'Uterine milk' under the influence of estrogen and progesterone hormone, composed of Protein, Fat and Glycogen. Uterine milk is part of the embryotroph. It is a white secretion containing proteins and amino acids that nourish the embryo during development. The uterine milk is the actual nutritional liquid that feeds the embryo, while the embryotroph is the uterine milk plus the syncytiotrophoblast. The uterine milk proteins (UTMP) are the major proteins secreted by the endometrium, primarily under the control of progesterone.
[#504] Spinose ear tick mainly pathogenic in which of the following stage
Correct Answer
(D) All of these

Solution: Spinose ear tick is mainly pathogenic in Larval stage, Nymphal stage and Adult stage.

As its common name suggests, the spinose ear tick's parasitic forms are usually found within the ears of the definitive host.

Marek's disease is caused by an alphaherpesvirus known as "Marek's disease virus" (MDV). c. Mycotic abortion is caused by fungi. Aspergilli were associated with approximately 5% of all abortion cases and 71% of 446 cases that were cultured for fungi and diagnosed as mycotic abortion. d. Trycomoniasis is caused by Protozoa. Trichomoniasis is a common sexually transmitted infection caused by a parasite.
