We used 360 nursery pigs (35 +/- 3 d of age) in two 21-d growth assays to determine the effects of soybean meal particle size on growth performance. In both trials, there were six pigs per pen and 10 pens per treatment. Pigs were weaned on d 21 and fed the same phase I diet for 7 d after weaning, followed by a phase II diet from d 7 to 14. On d 14, all pigs were weighed and randomly allotted to...

Marine algae have recently emerged as a new exciting source of biofuel. Our objective was to determine effect of supplemental defatted algal biomass from biofuel production on biochemical indicators of protein metabolism in plasma of weanling pigs. A total of 27 weanling pigs (BW = 10.69 ± 0.22 kg) were divided into 3 groups (n = 9/group), and fed a corn-soybean meal basal diet (BD), the BD plu...

The experiment investigated the effects of increasing dietary levels of bacterial protein meal (BPM) on various blood parameters reflecting protein and fat metabolism, liver function, and purine base metabolism in growing pigs. Sixteen barrows were allocated to four different experimental diets. The control diet was based on soybean meal. In the other three diets soybean meal was replaced with ...

Objective: The protein quality of earthworm meal was evaluated and compared to that of soybean meal (SBM) in two experiments using broiler chicks.  Methods: The protein quality of earthworm meal was evaluated and compared to that of soybean meal (SBM) in two experiments using broiler chicks. Results: The results of experiment 1 indicated that there were no significant differences between earthw...

these experiments were conducted to determine metabolizable energy and amino acid digestibilities of soybean meal, sunflower meal and canola meal in broiler chickens by using titanium oxide as indigestible marker in intact or caecectomized cockerels. ileal and total tract digestibility of amino acids were measured using broiler chickens, moreover, digestibility were also determined in the intac...

An experiment using 336 Hy-Line W-36 Single Comb White Leghorn hens was conducted to evaluate transgenic soybeans containing the gm-fad2-1 gene fragment and the gm-hra gene. Transcription of the gm-fad2-1 gene fragment results in an increased level of oleic acid (18:1) in the seed, and expression of the soybean acetolactate synthase protein (GM-HRA) encoded by the modified gm-hra gene, is used ...

BACKGROUND Although soybean meal (SBM) is excellent source of protein in diets for poultry, it is sometimes inaccessible, costly and fluctuates in supply. The SBM can partially be replaced by full-fat SBM, but the meals prepared from raw full-fat soybean contain antinutritional factors. To avoid the risk of antinutritional factors, heat treatment is always advisable, but either excessive or und...

C ONSISTENCY of carcass fat may be a factor in pork quality (Harrington, 1958). Barber et al. (1957) and Beltis (1961) reported that dietary copper supplements adversely affected the carcass grades of market pigs. Taylor and Thomke (1964) observed that copper supplementation of the diet resulted in a softening of the depot fat as indicated by a significantly (P < .01 ) greater iodine value (Han...
