Mustard seed or rapeseed meals are one of the major protein sources for animals in most parts of the world. Therefore, rapeseed as an established raw material for the production of edible oils could be a promising alternative protein sources for animals. Although the level of replacement of 75% and 100% gave insignificant results compared to the control group in terms of carcass 44 Husain Abd Allah El-Fadaly et al.: Glucosinolates in Rabbit Nutrition: Biologically Detoxification, Growth Performance, Digestibility, Blood Constituents, and Carcass Characteristics measurements, in addition to the fact that most levels of blood measurements came in all experimental treatments within the normal range of rabbit blood serum rates, Experimental in the control group Taking into account the economic cost, the substitution has a distinct production value.Ībstract The worldwide increasing demand for proteins as human nutrition and animal feeding leads to a growing interest on other protein sources.
Rabbit fed diets containing 25, 50, 75, and 100% RSM-protein significantly (P<0.05) showed higher concentrations of serum GSH and TAC than those fed the control diet. The increase was gradual, with the control group 0% RSM (T1) being the lowest and the highest in the group where the replacement was 100% RSM (T5), using RSM in rabbit diets significantly (P<0.05) increased serum Glutathione reduced concentration (GSH), and Total Antioxidant Concentration (TAC) for 25, 50, 75, and 100% RSM-protein. The trend of the antioxidant markers in the rabbits' blood stream was increasing as the watercress increased. At the end of the feeding period (10 weeks of age), all rabbits were fasted for 12 hrs. It could be concluded that substitution of rocket seed meals up to 50% of soybean meal in the diet of V-Line rabbits had good results without adverse effects on growth performance. The five diets contain approximately 18% protein, 14% fiber, and their components are as follows: Soybean, barley, maize, yellow corn, mint and kernels, derris, hemp, limestone, and food salt as well as seedling of watercress in one of the safe breeds. The experiment was divided into five groups of modern male rabbits weaning, the V-line Spanish species, in each group of 5 animals, age 31 days, where we were weaned at 30 days. The aim of the study was to investigate the effects of partial and total substitution (25, 50, 75, and 100%) of soybean meal of control diet with agro-industrial by-products as the source for plant protein, rocket (Eruca sativa) seed meals (RSM) processor of solid state fermentation using Aspergillus oryzae, on growth performance, nutrients digestibility, blood constitutions, carcass characteristics and economic efficiency.
