Effects of milk replacer composition on growth, body composition, and nutrient excretion in preweaned Holstein heifers.
Twenty-four newborn Holstein heifer calves were fed 1 of 4 milk replacers (MR): control (20% CP, 21% fat; MR fed at 441 g/d); high protein/low fat (HPLF; 28% CP, 20% fat; MR fed at 951 g/d); high protein/high fat (HPHF; 27% CP, 28% fat; MR fed at 951 g/d); and HPHF MR fed at a higher rate (HPHF+; 27% CP, 28% fat; MR fed at 1,431 g/d). Dry calf starter (20% CP, 1.43% fat) composed of ground corn...
متن کاملInfluence of equalizing the gross composition of milk replacer to that of whole milk on the performance of Holstein calves.
This study compared the performance of female Holstein calves fed either whole milk (WM) or milk replacer (MR) having similar gross composition to WM. Calves (n = 20) were separated from their mothers within 2 h of birth, weighed, moved into individual pens, and fed colostrum (10% of their BW over 2 feedings daily) for the first 3 d. Calves were alternately assigned to either WM (n = 10) or MR ...
متن کاملEffects of Concentrate Source (Cottonseed vs. Barley)on Milk Performance and Fatty Acids Profile of Holstein-Friesian Dairy Cows
Milk performance (protein and fat content) and milk fatty acids (FA) profile of dairy cows under supplementation with two sources of concentrate, oilseeds (C, cottonseed) at two levels, low (5kg DM/cow/day) and high (7 kg DM/cow/day), and cereal grains (B, barley) at high rate (7 kg DM/cow/day), were studied in three herds (n=36) of spring calving Holstein-Friesian dairy cows (200 days in milk)...
متن کاملGrowth, Blood Metabolites, and Health of Holstein Calves Fed Milk Replacer Containing Different Amounts of Energy and Protein
This study was conducted to compare the effects of feeding high protein and low energy milk replacer (HPR; CP 25%, ME 3.6 Mcal/kg DM) with low protein and high energy milk replacer (HPR; CP 21%, ME 4.2 Mcal/kg DM) on feed consumption, body weight (BW) gain, health and selected blood metabolites in Holstein calves during the pre-weaning period. At each feeding, each milk replacer (MR) was prepar...
متن کاملImmune Responses and some Blood Metabolite Responses of Female Holstein Calves to Dietary Supplementationwith Licorice Root (Glycyrrhiza glabra)
Different medicinal plants have been used in animal and poultry nutrition in last decade. It seems that there are some potential to these medicinal plants to replace with common antibiotics. Licorice root (Glycyrrhiza glabra) is a medicinal plant that extensively was used in different studies. In the present study, the effect of dietary addition of licorice root on performance and blood energy ...
