Colostrum Quality Begins Before Calving
Dairy producers and calf-care professionals devote considerable attention to providing young calves with the best possible environment. Clean, dry bedding, adequate ventilation, comfortable housing, and consistent feeding practices are essential components of successful calf management. Yet even the best facilities and management practices cannot compensate for inadequate colostrum quality or insufficient transfer of maternal antibodies. A calf that begins life without adequate passive immunity remains vulnerable to disease, regardless of how carefully its environment is managed.
What Are Your Fresh Cows Losing Besides Weight?
A dairy cow can lose considerable weight after calving without attracting much attention. Some weight loss is expected as milk production increases, feed intake struggles to meet energy requirements, and body reserves are mobilized to support lactation. The challenge is determining when this normal physiological adjustment becomes excessive and begins to compromise health, reproduction, and productive longevity.
Strong Cattle Prices, Weakening Confidence: What, Me Worry?
Cattle prices remain strong, yet American livestock producers are becoming less optimistic about the future. The latest Purdue University-CME Group Ag Economy Barometer reveals a growing concern that favorable market prices may not be enough to offset rising production costs and uncertainty about future profitability.
The Best Chicken Is Not Always the Best Layer
Open a poultry catalogue today and you will find chickens bred to do one job exceptionally well. Commercial layers are selected to produce large numbers of eggs, while broilers are bred to grow rapidly and efficiently convert feed into meat. Under the conditions for which they were developed, these birds are remarkably productive.

Strategies to Improve Dairy Cows' Feed Intake during Heat Stress
Extended periods of high ambient temperature coupled with high relative humidity compromise the ability of cows in lactation to dissipate excess body heat. Cows with elevated body temperatures exhibit lower intakes and milk yields. Supplemental fan cooling in combination with low pressure feed bunk sprinklers can reduce the effects of heat stress on milk production and feed intake. Several key areas of nutritional management should also be considered for complementing environmental cooling during hot weather.

DDGs as a Postbiotic Feed Ingredient in Dairy Cows
Intestinal barrier integrity plays a central role in the health and productivity of lactating dairy cows, particularly during periods of heat stress and metabolic strain. Distillers dried grains with solubles (DDGS), traditionally valued for their protein and energy contribution, also deliver fermentation-derived bioactive compounds. These components position DDGS as a potential postbiotic feed ingredient, with implications for gut permeability, immune activation, and oxidative stress regulation in dairy nutrition.
