Autor: E. Mahjoubi, S.A. Mousaviara, M. Hossein Yazdi, M. Hosseinzadehakandi, J.A.A. McArt

Publikováno v: Journal of Dairy Science, Vol 106, Iss 10, Pp 7320-7328 (2023)

ABSTRACT: Recent studies have shown that cows with subclinical hypocalcemia (SCH) at 4 d in milk (DIM), regardless of their blood Ca concentration before that time point, suffer from an increased early-lactation disease risk and reduced milk yield, w

The Effect of Using Rumen Protected Methionine (Mepron) on Production and Reproduction Performance of Holstein Lactating Cows during Early Lactation under Field Condition

Autor: M. Khorvash, H. Yazdani, E. Mahjoubi, R. Kowsar, Gh. Ghorbani

Publikováno v: پژوهشهای علوم دامی ایران, Vol 4, Iss 2 (2012)

In order to examine the effect of using rumen protected methionine (Mepron, Evonik Industries, Hanau, Germany) on productive and reproductive performance under field condition, 195 Holstein cows were used in a unbalanced completely randomized design

Does the time of microencapsulated sodium butyrate supplementation have any effect on the growth performance and health of Holstein dairy calves?

Autor: M. M. Eskandary, M. Hossein Yazdi, E. Mahjoubi, M. Kazemi-Bonchenari

Publikováno v: The Journal of Agricultural Science. 161:117-127

The optimal feeding time of microencapsulated sodium butyrate (SB) in whole milk (WM) and starter feed on growth performance and health in dairy calves was evaluated. Forty-eight newborn Holstein calves (body weight (BW) = 39.45 ± 2.48 kg) were rand

The time spent in fresh cow pen influences total lactational performance

Autor: M. Hossein Yazdi, D. Zahmatkesh, E. Mahjoubi, R. A. Patton, F. Hoseyni

Publikováno v: The Journal of Agricultural Science. 158:247-253

This research paper addresses the effect of different grouping strategies of fresh cows on total lactational and reproductive performance. Hundred-sixty multiparous Holstein cows were enrolled in a completely randomized design and assigned to one of
