Evaluating lysine requirements of nursery pigs fed low protein diets with different sources of nonessential amino acids.
The Lys requirement of nursery pigs may be dependent on the source of nonessential AA (NEAA) nitrogen or the source of Lys itself. However, little peer-reviewed data examines these phenomena. The objectives of these experiments were to determine if the Lys requirement of pigs is altered when 1) low protein diets are supplemented with different sources of NEAA nitrogen or 2) Lys is supplied as a...
متن کاملLack of influence of nursery temperature on the response of weanling pigs to supplemental vitamins C and E.
Three trials using 240 weanling pigs were conducted during winter months to determine the influence of nursery temperature ("comfortable" vs "cold") on the response of weanling pigs to added vitamin C (700 ppm) or E (55 IU/kg) to a corn-soybean meal diet. A "comfortable" temperature schedule (27 C initially with a weekly 2 C drop) was maintained in one nursery, with the temperature schedule in ...

The current study was evaluated the increased dietary protein level supplied either by soybean meal or meat meal sources (SBM vs. MM) in growing Holstein male calves on performance, blood metabolites, liver enzymes and insulin. 36 growing Holstein male calves averaging 167.7 kg body weight were allocated in a competently randomized design (12 animals/each) in 3 treatments; 1) basal protein leve...
متن کاملSynchronization of Energy and Protein on Supply Synthesis Microbial Protein
Synchronization of rumen available protein and energy is one of the conceptual methods to increase the efficiency of utilization of nutrients by the ruminants The concept of synchronization energy and protein was first by Jhonson, Implying that maximum microbial protein synthesis could be achieved by matching the rate of Organic Matter and protein degradation. Synchronization of rumen available...
