Plasma anti-Müllerian hormone profile in heifers from birth through puberty and relationship with puberty onset.

The current study aimed to define the plasma profile of anti-Müllerian hormone (AMH) and follicle stimulating hormone (FSH) in heifers during postnatal life until achieving puberty, as defined by plasma progesterone (P4) profile, to demonstrate a relationship between AMH and age of puberty onset. Blood samples collected from 11 Japanese Black female calves within 1 week after birth (W 0) and then biweekly until the sixth week after puberty (WP 6) were assayed for AMH, FSH, and P4. The heifers were classified into two groups based on age of puberty onset: ≤42 weeks (early puberty group; EP, n = 4) and ≥44 weeks (late puberty group; LP, n = 7).

Persistent organochlorine pesticides residues in cow and goat milks collected from different regions of Ethiopia.

The present study investigated the bioaccumulation of organochlorines in two milk-producing animals (goats and cows) grazed on the same feed to explore the extent of organochlorines availability in milk and any species effect on the bioaccumulation pattern. Six organochlorine pesticides: aldrin, α-endosulfan, β-endosulfan, p,p'-DDE, o,p'-DDT and p,p'-DDT were determined in samples collected from four regions in Ethiopia. Aldrin (11.
