Hydrolyzed feather meal as a protein source for growing calves.
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....
متن کاملNutritional Value of Soybean Meal
Protein feeds in the European Union (EU) cover only 25% demand for protein, what oblige the particular members to import feeds with a high protein content, where the main place have soybean meal. The share of this feed in total quantity of feeds utilization in EU is about 9%. Yearly consumption of soybean meal in EU is about 32mln ton, from what 5.6% it falls on Poland (Rynek Pasz, 2010). Polan...
متن کاملAmino acid supplementation of hydrolyzed feather meal diets for finisher pigs.
The objective of this study was to determine the possibility of replacing soybean meal (SBM) in finisher pig diets completely with hydrolyzed feather meal (FM). Forty-five gilts and 45 castrated males (57.8+/-0.8 kg of BW; 3 gilts or 3 castrated males/pen) were randomly assigned to 5 finisher-1 diets with 6 pens per diet. At an average pen BW of 81.0+/-1.4 kg, pigs were offered finisher-2 diets...
متن کاملImproving the Nutritional Value of Sunflower Meal by Electron Beam and Gamma Ray Irradiations
This research was performed to compare electron beam (EB) and gamma ray (GR) treatments at doses of 25, 50 and 75 kilo Gray (kGy) on ruminal degradation kinetics and in vitro digestibility of sunflower meal (SFM). Ionizing radiations of EB and GR had significant effects )P
متن کاملHydrolysis time as a factor affecting the nutritive value of feather meal and feather meal-blood meal combinations for growing calves.
The objectives of this research were to determine 1) the effects of hydrolysis time on feather meal (FTH) protein digestion and ruminal escape and 2) whether adding blood meal (BM) to FTH evoked a complementary response in animal performance. A lamb digestion trial was conducted to estimate true protein digestibility of soybean meal (SBM), BM, and FTH hydrolyzed for 10, 12, 15, or 18 min. Rumin...
