The possibility of predicting kilograms of lean pork, the percentage of lean, and lean gain per day using measurements taken during the early finishing phase was studied using real-time ultrasound measurements on 164 barrows. Initial live weight (IWT

Twelve steers (373 kg initial BW) were used in three simultaneous 4 × 3 incomplete Latin squares to evaluate the effects of supplemental corn (1.8 kg/d, 0.14 kg CP/d), cooked molasses block (0.45 kg/d, 0.14 kg CP/d), and rumen-protected methionine (

Selenium is an essential micronutrient, taken up by plants from the soil and ingested by animals in feeds and forages. Problems occur with it, at both ends of the supply spectrum. When it is present in excess, it causes loss of hair, separation of ho

We developed two different ketogenic diets, which will allow us to understand the mechanisms of ketosis in lean and obese female and male Zucker rats. The obese Zucker rat has a point mutation in the long form of the leptin receptor causing these rat

A fermentation balance equation was used to estimate the extent of fermentation of rations fed at or near voluntary intake to lactating dairy cows. The rations varied in hay to concentrate ratio from 100 :0 to 20 :80 and in four trials the high conce

Indirect calorimetry was used in total energy balance trials with six mature, lactating, nonpregnant Holstein cows to study the utilization of metabolizable energy (ME) for milk production. An orthogonal set of 3×3 extra-period Latin-squares was use

Summary Three rations in which the proportion of estimated net energy (ENE) derived from hay or a concentrate mixture of corn meal and soybean meal was varied from 50% hay–50% concentrate (Ration A) to 75% hay–25% concentrate (Ration B) or 100% h

Results of 543 energy balance trials with lactating cows were summarized to partition the energy required by lactating cows into maintenance and production components and to determine the influence of energy source on the efficiency with which dietar
