Effects of Feeding Different Levels of Flaxseed on Performance, Nutrient Digestibility and Blood Parameters of Pre-Weaning Calves
In this experiment, we used 15 newborn Holstein male calves that their initial weight was 41 ± 4.5 kg and their age was one week. The experiment was conducted in a completely randomized design with three treatments and five replications. Treatments included: 1- control treatment without flaxseed, 2- treatment containing 5% flaxseed and 3- treatment containing10% flaxseed. Flaxseed replaced ...
متن کاملGrowth Performance and Feed Conversion Efficiency of Crossbred Heifers
Theexperiment was conducted to investigate the growth performance and feed conversion efficiency of crossbred heifer at different age level in Government Dairy Farm in Bogra, Bangladesh. Twelve female crossbred heifers were equally distributed (n=3) into four groups [Group A: (7±2 months), B: (12±2 months), C: (15±2 months) and D: (20±2 months)] according to age and fed concentrate mix, rice st...
متن کاملEffects of Feeding Levels of Starter on Weaning Age, Performance, Nutrient Digestibility and Health Parameters in Holstein Dairy Calves
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...
متن کاملEffects of Irradiated Flaxseed on Performance, Carcass Characteristics, Blood Parameters, and Nutrient Digestibility in Broiler Chickens
The objective of this study was to investigate the effects of feeding electron irradiated flaxseed (FS) on performance, carcass characteristics, blood parameters, digesta viscosity, and nutrient digestibility in broiler chickens. In a 2 × 2 factorial arrangement, 320 day-old broiler chicks were randomly assigned to one of five experimental diets, each with four replicates containing 16 chicks e...
متن کاملEffect of Saccharomyces Cerevisiae Yeast and Butyrate Monoglycerides on Performance, Blood Parameters and Nutrients Digestibility in Holstein Suckling Calves
The aim of this study was to investigate the effects of saccharomyces cerevisiae yeast and butyrate monoglycerides on the performance, blood parameters and nutrients digestibility in suckling Holstein calves. For this experiment, 32 newly-born Holstein calves (average age 1-8 days; average weight 38±1 kg) were used in a completely randomized design with 2×2 factorial arrangement, 4 treatmen...
