Blastocist stage During this stage, the dividing zygote will yield millions of cells which are enclosed within the zonapellucidal  and this is called blastocist. Blastocist is a ball of many cells enclosed by a membrane called zonapellucidal. During this stage, the Blastocist feeds from the uterus by means of diffusion. In the Ewe for instance, one to three or four lambs are normally produced but up to ten eggs maybe fertilized during fertilization or during mating particularly when when females are super ovulated. The Blastocist stage following fertilization will last for about 10days in sheep and pigs and 11days in cattle . ii. Embryonic stage This is the second stage in prenatal growth. Cell differentiation into tissues and organs are beginning to show or manifest. These differentiating cells have a very high priority for nutrien

1. Anthrax disease of ruminants : Anthrax, a highly infectious and fatal disease of cattles, is caused by a relatively large spore-forming rectangular shaped bacterium called Bacillus anthracis . Anthrax occurs on all the continents,causes acute mortality in ruminants. The bacteria produce extremely potent toxins which are responsible for the ill effects, causing a high mortality rate. The bacteria produce spores on contact with oxygen.  Signs of the illness usually appear 3 to 7 days after the spores are swallowed or inhaled. Once signs begin in animals, they usually die within two days. Hoofed animals, such as deer, cattle, goats, and sheep, are the main animals affected by this disease. They usually get the disease by swallowing anthrax spores while grazing on pasture contaminated (made impure) with anthrax spores. Inhaling (breathing in) the spores,which are odorless, colorless, and tasteless, may also cause infection in animals and people. In the c
