The age at first consumption of forage in calves and its effect on growth and rumination in the short- and long-term

Journal of Animal Science and Biotechnology, 2023
Background Previous investigations into the effect of dietary forage on calf performance have been inconsistent, and there is a paucity of information exploring the effect of age on the growth performance and rumination of calves.

Postbreeding Heifer Management [PDF]

Veterinary Clinics of North America: Food Animal Practice, 2013
Rebreeding performance of the first-calf heifer has major economic consequences for cow-calf producers. Management systems that allow heifers to cost-effectively achieve a body condition score of 5 to 6 at calving and maintain this through rebreeding have a higher probability of pregnancy success.

Investigation of Body Development in Growing Holstein Heifers With Special Emphasis on Body Fat Development Using Bioelectrical Impedance Analysis

Frontiers in Veterinary Science, 2021
This study analyzed skeletal development, body condition, and total body fat development of growing heifers. A total of 144 female primiparous Holstein cattle from four commercial dairy farms with different degrees of stillbirth rates were examined ...

An empirical analysis of the cost of rearing dairy heifers from birth to first calving and the time taken to repay these costs [PDF]

, 2017
Rearing quality dairy heifers is essential to maintain herds by replacing culled cows. Information on the key factors influencing the cost of rearing under different management systems is, however, limited and many farmers are unaware of their true costs.

Long-term effects of early-life rumen microbiota modulation on dairy cow production performance and methane emissions

Frontiers in Microbiology, 2022
Rumen microbiota modulation during the pre-weaning period has been suggested as means to affect animal performance later in life. In this follow-up study, we examined the post-weaning rumen microbiota development differences in monozygotic twin-heifers ...

Dietary Concentrate Supplementation Alters Serum Metabolic Profiles Related to Energy and Amino Acid Metabolism in Grazing Simmental Heifers

Frontiers in Veterinary Science, 2021
Supplementation plays a vital role in the growth performance of grazing heifers. We investigated the effects of maize-based concentrate supplementation on the serum metabolome in grazing heifers. Twenty-four 7-month-old heifers (211.65 ± 4.25 kg BW) were
