forty-two weaned lori-bakhtiari lambs were taken in an investigation for the effects of two-nutritional management methods of restricted vs. re-alimentation feeding on intake, growth and as well on the cost benefit analysis. during the feed restriction period (frp), the control (c) animals were fed low-quality roughage ad libitum, plus mixed concentrate. the restricted animals (r) were fed only...

Poor-quality roughages are widely used as fiber sources in concentrate-based diets for ruminants. Because roughage quality is associated with the efficiency of energy use in forage-based diets, the objective of this study was to determine whether differing the roughage source in concentrate-based diets could change the energy requirements of growing lambs. Eighty-four 1/2 Dorper × 1/2 Santa Inê...

The aim of this study was to produce high-quantity safe beef product while maximising the use of domestic grass resources. We would like to apply “metabolic imprinting”, which is based on medical research regarding “the developmental origins of health and disease (DOHaD)” to beef production. In this study, we investigate, using molecular biology and histochemistry methods, whether the metabolic...

In Exp. 1, six individually fed Hereford steers were exposed to hot (HOT) or thermoneutral (TNL) environmental conditions (ENV) while being adapted (stepped-up) to a finishing diet by decreasing roughage level from 55 to 10% of the diet DM over 17 d. Only at 10% roughage did heat exposure result in reduced (P<0.05) calculated ME intake (MEI) and measured DMI. In the TNL treatment group, pulse r...

The present study was carried out to establish knowledge of consequence for setting up guidelines of importance for production of competitive organic pork of high quality. Performance and meat quality characteristics were compared between three organic pig production systems based on indoor housing with access to an outdoor area and a Danish conventional indoor system including 100% concentrate...

Objective: The objective of this experiment was to compare the subsequent growth performance and carcass impacts a high-energy diet limit-fed at 2.2% body weight (BW) or traditional roughage-based fed ad libitum during growing phase.

The objective of this experiment was to compare performance impacts a high-energy diet limit-fed at 2.2% body weight (BW) daily on dry matter (DM) basis traditional roughage-based fed for ad libitum intake during the growing phase.

Hereford steers (n = 280, BW = 371 +/- 29 kg; 40 pens) were used to evaluate two alternatives to ad libitum access to feed and constant roughage levels in finishing diets. The eight treatments were as follows: two treatments in which intake was limited to a multiple of the maintenance (MM) energy requirement (2.1, 2.3, 2.5, and 2.7, [2.7MM] and 2.3, 2.5, 2.7, and 2.9 [2.9MM] times maintenance f...

Six castrated male Karagouniko sheep, offered three levels of water, were used in a 3x3 Latin Square design to study the effects of mild water restriction on roughage intake and digestion. The three treatments were offered water ad libitum throughout the day (A), made available to the animals for 1h daily (B) or 65% of the water consumed ad libitum (C). Sheep in Treatment A consumed more water ...

A complete diet (Total Mixed ration) with sorghum stover (40%) as sole roughage source was prepared and offered to animals under two forms: as mash or as expanded-extruded pellets (EEP). These two complete diets were compared with a conventional diet (ad libitum chopped sorghum stover fed separately with concentrate mixture to meet 80% of protein requirements). These three diets were randomly a...
