Similarly, if new animals will be entering the herd, it is always best to vaccinate them at least a week prior to their assembly and movement, rather than waiting until they arrive in the herd.

Superficial cells: Large cells with angular cytoplasmic edges and pyknotic to absent nuclei, indicating peak estrogen levels have been reached and are characteristic of the fertile period, which is better defined by serial progesterone +/- LH testing. Proestrus lasts from 3 days to 3 weeks, with 9 days average. Before moving, test all cattle not previously tested for persistent BVDV infection (BVDV carriers). Mean levels of FSH are moderately increased, and those of LH slightly increased, during anestrus. Vaginal cytology is abruptly altered by the reappearance of parabasal epithelial cells and frequently neutrophils, known as the diestrual shift. hV[oJO#v.KFZ!Q(-.+!R2B=pl4zb{gG0%D3F@9 "BjU$RH5@ND6`Zp:^+'yot.2^8.`AqP$G@B'=!giwzjj!X*_ZoJy\D3`e{D"B {`fHe Q{::rTZp]" &S\Zx}2ujS0K{xQI{yV&d$)3/t9$FKNAz_6ep^*^zkxbt4t GQocSmIP>i8'CZm-*6g$sN-ha_xMwhwRn]AY0!:BLf#SSl'zByw_In"u>-#Hg?

Increases in these enzymes may occur when the pancreas is inflamed, although they can also be elevated with kidney or intestinal disease, and when certain drugs are used. Vaginal cytology shows a progressive shift from parabasal cells to small and large intermediate cells, superficial-intermediate cells, and finally superficial epithelial cells, reflecting the degree of estrogen influence.

The normal canine reproductive cycle can be divided into four phases, each having characteristic behavioral, physical, and endocrinologic patterns, although considerable variation exists. Do not purchase them through an auction market or move them with unknown cattle due to the high risk of exposure to BVDV under these conditions. It is collected in abattoirs inspected by the competent authority of the country of origin. FDA uses the internal data systems to verify registration, LACF/AF process filing, when required, or other product requirements and to determine if the firm/product is subject to DWPE. Evaluation of the estrous cycle for true abnormalities is an important part of the evaluation of an apparently infertile female dog, many of which have not had accurate timing performed or have been bred with poor husbandry or to a subfertile male.
