Growth, digestion and in situ studies were conducted to determine the protein value of hydrolyzed feather meal (Fth) for growing ruminants. Dacron bags containing blood meal (BM), Fth, corn gluten meal (CGM) and soybean meal (SBM) were suspended in the rumen of two steers for 12 h to estimate escape protein. The escape protein value for Fth, 69.1%, was less than that for BM (82.8%) and CGM (80....

Commercial White Leghorn hens (65, 63, or 70 wk of age in Experiments 1, 2, and 3, respectively) were induced molted by feed withdrawal until approximately 28% body weight was lost. All hens were then weighed, and seven replicate groups of 12 hens each were fed molt diets. In Experiment 1, three diets consisted of a corn basal diet (7.9% CP) or this diet supplemented with corn gluten meal (CGM)...

Two experiments were conducted to evaluate the effects of 1) two grain mixtures and 2) various carbohydrate sources and levels fed to weanling pigs during the initial 2 wk postweaning. A total of 720 crossbred pigs were weaned at 23 +/- 2 d of age at an average BW of 5.8 kg. In Exp. 1, a 2 x 3 factorial experiment in a randomized complete block design was conducted in 12 replicates. Treatment d...

Costs of compounded diets containing fish meal as a primary protein source can be expected to rise as fish meal prices increase in response to static supply and growing demand. Alternatives to fish meal are needed to reduce production costs in many aquaculture enterprises. Some plant proteins are potential replacements for fish meal because of their amino acid composition, lower cost and wide a...

Data were collected on 130 intact male lambs fed diets based on roughages supplemented with fish meal, soybean meal, or corn gluten-blood meal and slaughtered at 43 kg live weight. A nonsupplemented group served as a control. The lambs represented Romanov (R), Finnsheep (F), a new breed developed in Canada (DLS), Coopworth (C), and Suffolk (S), three first crosses of DLS with R, F, and Booroola...

in this research to investigate of the effect of tannin`s type and level on rumenal degradation of soybean meal (sbm) and canola meal (cm), two experiments have be done. at first experiment supplements were treated by semi-pure tannin of pomegranate-pistachio (pp), in different levels (0, 10 and 15 % of dm for sbm and 0, 5 and 10% of dm for cm). in second experiment, these supplements were trea...

Fifty-one yearling Angora doelings (20+/-0.6kg initial body weight (BW)) were used to determine effects of different dietary protein sources on BW change and mohair growth. Diets consisted of approximately 40% roughage and 18-19% CP (DM basis), of which two-thirds was supplied by corn gluten meal (CG), cottonseed meal (CT), hydrolyzed feather meal (FT) or menhaden fish meal (FI); DM intake was ...

The objective of this study was to examine the effect of combining ruminally degradable and undegradable CP sources on ruminal microbial protein synthesis and postruminal N and amino acid (AA) flows in steers. Six steers fitted with ruminal, duodenal, and ileal cannulas were fed diets containing corn silage and high-moisture corn supplemented with urea, soybean meal (SBM), dry corn gluten feed ...

In two experiments, 720 broiler strain cockerels were used to determine the effect of pressure and temperature on poultry offal meal (P.O.M.) quality. Poultry offal meals were subjected to 20, 28 and 35 pounds per square inch gauge (p.s.i.g.) steam pressure for <1 or 15 minutes (Experiment 1) and 15, 30 and 45 p.s.i.g. steam pressure for 15 or 30 minutes (Experiment 2). All pressures were allow...
