this study was carried out to assess the effects of alfalfa hay level and replacing corn grain by other grains in starter on daily feed intake, average daily gain (adg) and feed efficiency (fe) of pre and post-weaning dairy calves during the pre and post-weaning periods. for this purpose, a database meta-analysis used in the present study. statistical analyses were performed using proc mixed in...

The aim of this study was to evaluate the effect of replacing corn grain for sugar cane molasses (MO) or glucose syrup (GS) in the starter concentrate on performance and metabolism of dairy calves. Thirty-six individually housed Holstein male calves were blocked according to weight and date of birth and assigned to one of the starter feed treatments, during an 8 week study: i) starter containin...

The present study was conducted to evaluate the effects of physical form of starter and alfalfa hay (AH) provision on growth performance, ruminal fermentation, and blood metabolites of Holstein dairy calves. Forty-four 3d-old Holstein dairy calves with a mean starting BW of 39.9 ± 1.1 kg were used in a 2 × 2 factorial arrangement. The factors were dietary forage level (0 or 150 g kg-1</sup...

The objective of this study was to investigate the effects of different early weaning programs on growth performance and blood parameters of dairy calves. To meet this objective, thirty Holstein calves with initial body weight of 36 ± 5 kg were randomly assigned at birth to one of the three weaning programs. Experimental groups were: 1) starter diet and whole milk from birth to 6 weeks and wean...

To evaluate the effects of feeding four different levels of starter in male Holstein dairy calves, a completely randomized study was conducted, using 28 calves with initial body weight of 40.5±2.4 kg. The animals were fed iso-nitrogenous starter and were weaned when they consumed 350, 500, 650 and 800 g/d of starter for 3 d consecutively. Starter and water were available ad-libitum throughout t...

in order to investigate the effect of adding fennel powder (foeniculum vulgare) in starter diet on performance, immunity system and biometric parameters of holstein calves, 30 holstein calves (15 males and 15 females) with birth weight of 40±0.5 kg were used in a completely randomized design. experimental diets were: 1. starter without fennel powder (control), 2. starter containing 0.4% fennel ...
