Practical Economics of "accelerated" Calf Feeding Programs
نویسنده
چکیده
Physiologically, the newborn calf is not a functioning ruminant. The abomasum, which represents the largest portion of the stomach of the newborn calf, is the primary functional unit of the gastric region. The sucking reflex allows milk to bypass the rudimentary rumen and reticulum via the reticular or esophageal groove directly into the abomasum where digestion is initiated. Milk is coagulated in the abomasum through the action of the enzyme rennin, and digestion and absorption proceeds very much like that in the nonruminant.

Intensified Pre-Weaning Calf Feeding Programs: Impacts on Growth and Behavior
There are a range of viewpoints on how best to feed and manage dairy calves early in life. Traditional approaches to rearing dairy calves have focused on stimulating early solid feed intake through restricting intake of milk or milk replacer. A conventional milk feeding rate is approximately 10% of a calf’s birth weight, an amount that translates to between 4 and 5 L/day, supporting under 0.5 k...
متن کاملLeast Cost Rations for Beef Cows
Winter feeding costs represent between 50 and 60 cents of every dollar spent on keeping a cow a year. Thus, any attempt to control or reduce costs of operating a cow herd must focus on controlling or reducing feed costs. However, attempts at controlling or reducing costs are highly dependent on the forage system that the cow-calf operation uses. Forage systems vary depending on a variety of fac...
متن کاملComparison of a Long Yearling System and Calf-fed Performance and Economics
A study was conducted to determine differences in performance, carcass characteristics , and profitability of a calf-feeding and a yearling production system. Year-lings had higher daily gains compared to calf-feds; however, calf-feds were more efficient than yearlings. Yearlings produced more weight than calf-feds leading to an improvement in profitability for yearlings compared to calf-feds. ...
متن کاملExperiences with Free-access Acidified-milk Feeding in Ontario
Several Canadian producers have implemented an inexpensive free-access feeding system modeled on Finnish guidelines,18 using formic acid as a milk preservative. The system mimics natural suckling and permits group social behavior. It allows for accelerated growth and changes labor requirements for calf rearing. Anecdotally, producers report less clinical cases of diarrhea and use of drugs for r...
متن کاملProtein and Energy Nutrition of the Neonatal Calf
Choices made by nutritionists and milk replacer manufacturers of nutrient levels and milk replacer ingredients, coupled with choices by calf feeders about feeding rate and calf body weight, largely determine calf growth rate, efficiency of feed conversion, and cost of gain. These choices also largely determine later feedlot performance and carcass composition. For example, early calf nutrition ...
