The Optimal Dietary Threonine to Lysine Ratio for Growing Pigs
The growth of 64 pigs was monitored over grower and finisher periods of 26-58 and 58-96 kg respectively, to see if the optimum dietary ratio of threonine to lysine (T/L) under ad Zibitum feeding was higher than the generally accepted ratio of 0.6. Five basal (Bl-B5) diets were used to establish the pig’s response to lysine (in the range 6.0 to 11.24 and 5.59 to 10.5 g kg-1 for grower and finish...
متن کاملEffect of various dietary arginine: lysine ratios on performance, carcass composition and plasma amino acid concentrations of growing-finishing swine.
Crossbred growing-finishing pigs (112 barrows, 48 gilts) were used to determine the effect of reducing excess dietary arginine, through feedstuff variation, on performance, carcass composition and plasma amino acid concentrations. Diets contained five, four, three or two times the NRC requirement for arginine. Lysine in all diets was formulated to be equal to NRC requirements, and all diets con...
متن کاملResponses of growing broilers to diets with increased sulfur amino acids to lysine ratios at two dietary protein levels.
An experiment with 1,440 male Cobb 500 and 1,440 male Ross 308 broilers (14 to 35 d of age) was conducted to investigate the effects of diets having 4 levels of digestible methionine plus cysteine (SAA) on various performance criteria at 2 dietary protein levels (20.5 and 26.0%). Two corn-soybean meal/poultry by-product basal diets were formulated to contain 3,060 kcal/kg MEn and either 20.5 or...
متن کاملEffects of dietary metabolizable energy and protein on early growth responses of broilers to dietary lysine.
Two studies evaluated effects of metabolizable energy (ME), digestible Lys (dLys), and amino acid (AA) balance on broiler performance. In experiment 1 diets contained 3 levels of ME (3,000, 3,100, and 3,200 kcal/kg) in combination with 4 levels of dLys (1.05, 1.13, 1.21, and 1.29%). A fixed proportion of dLys relative to CP and key indispensable AA was maintained in graded increments of CP from...
متن کاملGrowth Performance, Feeding Behavior and Physiological Responses of Young Growing Holstein Male Calves to Dietary Chromium-Methionine (Cr-Met) Supplementation Related to Body Weight and Age
This study was conducted to investigate the effect of dietary chromium-methionine (Cr-Met) supplementation on growth performance, feeding behavior and physiological responses of Holstein male calves during two different phases of body weight (BW). Twenty six (153.5±9.83 kg of BW) male calves were divided in two groups (n=13) and randomly assigned to treatments: 1) control and 2) Cr-Met (1.1 mg ...
