Experiments were conducted with rats and swine to determine the potential of dietary alfalfa as a t rea tment for zearalenone (Z) toxicosis. Ninety-six female weanling Wistar rats were fed a casein-based semipurified diet containing 0, 15 or 25% alfalfa and 0 or 250 /~g Z/g feed. Exposure to Z for 14 d resulted in reduced growth, feed consumption and feed efficiency as well as kidney and liver ...

The feeding behavior of growing-finishing pigs reared under precision feeding strategies was studied in 35 barrows and 35 females (average initial BW of 30.4 ± 2.2 kg) over 84 d. Five different feeding programs were evaluated, namely a conventional 3-phase program in which pigs were fed with a constant blend of diet A (high nutrient density) and diet B (low nutrient density) and 4 daily phase-f...

We investigated the variation in eating speed by individual pregnant sows and the influence of feeding dry compared to wet feed. A total of 39 Norwegian Landrace × Yorkshire dry sows, 13 primiparous and 26 multiparous, were included in the experiment. In experimental period 1, each sow was offered 2.2 kg of a standard concentrate feed without added water. In experimental period 2, the sows were...

AIM To study the effects of combinations of fenugreek (Trigonella foenum-graecum L.), garlic (Allium sativum), and black pepper (Piper nigrum) powder supplementation on production traits of broiler chickens. MATERIALS AND METHODS A total of 288 commercial broiler chicks were randomly assigned to 1-9 groups with 4 replicates each. An experiment was conducted in broilers with different feed for...

Two experiments involving 288 pigs were conducted to determine the effects of shortterm feed restriction during the growing period on average daily gain (ADG), average daily feed consumption, feed required/unit of gain (F/G), age at 100 kg and average backfat depth at 100 kg. Pigs were fed 100, 85 or 70% of ad libitum consumption for 2or 4-wk periods in Exp. 1 and 100 or 85% for 2or 4-wk period...

Body weight, feed consumption, and mortality were measured in the 1957 Athens-Canadian Randombred Control (ACRBC) strain and in the 2001 Ross 308 strain of broilers when fed representative 1957 and 2001 diets. The dietary regimens were chosen to be representative of those used in the industry in 1957 vs. 2001. The 1957 diets were fed as mash, the 2001 starter was as crumbles, and the grower and...

Alternative production systems have increased popularity in the egg industry to address consumer demands for the production of commercial eggs that reduce concerns over animal welfare. This experiment was conducted at the NCDA&CS, Piedmont Research Station, in conjunction with the NCLP&MT. This study consisted of 6 replicates totaling 378 hens of a single commercial egg strain, housed in an enr...

Materials and methods: Ninety-six crossbred pigs 17 to 20 days old were randomly assigned to six experimental diets. A nonmedicated basal diet was supplemented with carbadox (55.12 g per tonne), copper sulfate (192.40 g copper per tonne), zinc oxide (2712.68 g zinc per tonne), or the probiotic feed additive BioPlus2B (Chr Hansen Inc, Milwaukee, Wisconsin; 1.1 × 106 or 1.3 × 106 spores per gram ...
