in order to investigate effects of partial replacement of starch with neutral detergent soluble fiber (ndsf) on weekly weight gain, feed intake, feed conversion ratio, digestibility and some histopathological changes of rumen, 16 lambs were used in completely randomized design. the experimental period was 70 days. dietary treatments were 1- control (high starch), 2- beet pulp, 18 percent, 3- be...
Background & Aim: Medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.This experiment was conducted to investigate the effects of milk thistle (MT) and thyme seeds (TS) on the performance in broilers. Experimental: In this study, 160 one-day-old (Ross 308) male broiler chicks were divided randomly into four major groups with 4 replicates b...
Effect of supplemental phytase on phosphorus and protein utilization and performance of broiler chickens fed on eight different wheat varieties were evaluated. The phytate contents of wheat varieties were determined. In a completely randomized design with a 8*3 factorial arrangement, 384 day-old commercial male brioler chicks (HubbardPeterson) were divided into 96 groups, four chicks per group...
Although the feed-conversion ratio is recognized as a prominent indicator of profitability for pork producers, only 212 (50.7%) of 418 producers who were asked the feed-conversion ratio for finisher pigs provided a response during the USA National Animal Health Monitoring System 1995 National Swine Study. Of these, 126 (59.4%) producers furnished a feed-conversion ratio which they characterized...

Two experiments were conducted to evaluate the nutritional value of millet and tallow for broiler chickens. In the first experiment, the nitrogen corrected apparent metabolizable energy (AMEn) of millet and tallow were determined by the method of Sibbald. In the second experiment, a 3×5 factorial experiment was designed to evaluate the effects of 3 levels of tallow and 5 levels of substitution ...

watermelon seed full-fat (wmsf) and watermelon seed meal (wmsm) samples were analyzed for proximate composition and then incorporated in broiler chicks diets at increasing levels up to 20%. feeding increasing levels of wmsf to broiler chicks for up to 20% increased weight gain (p
Two experiments were designed and conducted to evaluate the effect of tallow and the nutritional value of millet and the effect of substituting millet for corn on the performance of laying hens. In the first experiment, the nitrogen corrected true metabolizable energy (TMEn) of tallow and millet was determined. Also the digestibility of dry matter (DM), protein, fat and crude fiber of millet wa...
The present study was performed to investigate the effects of dietary electrolyte balance and probiotic on the performance and carcass characteristics in Japanese quail under heat stress conditions. A total of 672 quail chicks (20-day old) were studied in a three-factor, factorial experiment with 4 replicates and in each replication of 14 birds during 20 to 37 and 20 to 41 days Factors included...
