Rice gluten meal as an alternative by-product feed for growing dairy calves

Abstract

This experiment aimed at studying the nutritional characteristics and feeding value of rice gluten meal (RGM, a wet-milling by-product of rice) in growing dairy calves. RGM contained 464 g/kg of crude protein with 821 and 196 g/kg nitrogen (N) of borate-phosphate insoluble N and acid detergent insoluble N, respectively, which were higher (P < 0.05) than groundnut cake (GNC). In vitro gas production, organic matter digestibility and energy values were comparable between RGM and GNC. For in vivo trial, 18 Karan-Fries calves (6-12 months) were randomly assigned into three groups based on comparable body weight and age. The first group (GP-I) was fed concentrate mixture containing mainly GNC as protein source, whilst it was replaced by RGM up to 50 and 75 % on N basis, in second (GP-II) and third (GP-III) groups, respectively. Thus, RGM constituted 140 and 210 g/kg of concentrate mixture of GP-II and GP-III, respectively. In addition, all animals were offered chopped green maize and wheat straw for the whole experimental period of 90 days. Results revealed that there was no difference in intake and digestibility of nutrients, N balance, average daily gain (ADG) and feed efficiency among three groups. Nevertheless, RGM-based diets produced cost-effective ADG than GP-I. Furthermore, experimental calves did not differ in haematological variables like glucose, blood urea N, plasma proteins and non-esterified fatty acids. This study demonstrated that RGM could be incorporated successfully in the concentrate mixture, replacing 75 % of GNC without any discernable compromise in the performance of growing calves.

Effect of Feeding Rice Gluten Meal (RGM) on Haematological, Serum Biochemical and Carcass Traits in Broilers

“…Experimental diets ingredients and nutrient composition as prestarter (0-2 wk) and starter (2-3 wk) diets have been given in table 1 and finisher diets (3-6 wk) in table 2 as per ICAR (2013) Kumar et al, (2016) reported lower values of RGM in terms of protein (46.40%) and EE (3.40%) as compared to our results. Furthermore, the drying process can have crucial influence not only on variability of nutrients but also on concentration and availability of nutrients in different samples.…”

“…Metwally and Farhat (2015) who reported no significant (P>0.05) difference in serum biochemical parameters (serum lipid profile, glucose, total protein, albumin and globulin) up to addition of 12.5% RGM in diet of broiler chicken. Kumar et al, (2016) also reported no difference in the serological variables (glucose, blood urea nitrogen, plasma proteins and non-esterified fatty acids) on addition of RGM up to 21% level in the diet of growing dairy calves. Our results were in agreement with Metwally and Farhat (2015) and Kumar et al, (2016).…”

Our results were in agreement with Metwally and Farhat (2015) and Kumar et al, (2016). All the values of various serological parameters were ranges between normal physiological values up to 20% inclusion level of RGM.…”

“…Metwally and Farahat (2015) found that broiler fed RGM with different inclusion rates up to 12.5% had the same growth performance, carcass traits and serological parameters. Kumar et al, (2016) found that RGM could replace ground nut cake (GNC) in the concentrate mixture of growing calves up to 75% level without any adverse effect on growth performance and serological parameters. Malik et al, (2017) reported that replacement of ground nut cake (GNC) by RGM and maize gluten meal (MGM) at 75% level did not differ in feed efficiency and average daily gain (ADG) in growing Sahiwal cattle.…”

Feeding value of rice gluten meal as an alternate protein source in broiler chickens

“…Rice gluten meal (RGM), a by-product of wet milling of rice, is available in appreciable amounts at a lower cost compared to soybean. Rice gluten meal (RGM) contains 3152 kcal metabolizable energy (ME) per kg, 46.45% crude protein (CP), 3.4% ether extract, and a favorable amino acid profile with relatively high abundance of methionine (3). It has been also designated as a source of rumen nondegradable protein with the highest known metabolizable protein value among plant proteins (4).…”
