In vivo nutritive value of rice feed for sheep and its application for cattle feed

Abstract

The objective of this study was to evaluate the nutritive value of polished rice (PR) vs unpolished rice (UPR) as a potential feedstuff for sheep in order to use as a replacer to corn in sheep diet, and as well as to present the application in the formulation of cattle diet. Six corriedale ewe were randomly assigned to each treatment. UPR and PR were provided as a dietary treatment together with timothy grass as a basal diet in a crossover design for two period with 15-d duration for each period. The ratio of experimental and basal feeds were 33.3% and 66.7%, respectively. The differences in the total digestible nutrient (TDN) contents between sheep and cattle was determined according to the references. The number of data collected sheep and cattle was 9 and 17, respectively. The PR showed higher nutrients digestibility than UPR. Similarly, higher TDN content was observed PR than UPR (p < 0.05). As a result, the replacement of corn in the formulate feed with UPR and PR feed rice could be possible with the ratio of 91.2% and 100.0%, respectively. The result of comparation the TDN contents of UPR and PR in sheep and cattle, the PR has no difference in the nutritive value which suggests the applicability of the results of sheep to cattle. On the other hand, UPR has known to have different nutritive value between sheep and cattle, so caution should be taken when preparing formula feeds for cattle.

In vitro ruminal fermentation kinetics of alternative supplemental feeds formulated with by-products from food crops

“…Previous reports suggested that the nutritive value of agro-by-products is generally low (Yanti and Yayota 2017) and varied widely (García-Rodríguez et al, 2019). While the ber contents of the feedstuffs used in this study were relatively high as expected(Kalpanadevi et al 2018;Kim et al, 2019), the CP contents were unusually high as well, ranging between 77.3-215 g/kg DM. Of note was the CP content of rice hull which is signi cantly higher than most previous reports(Okoruwa et al, 2012…”

In Vitro Digestibility and Fermentation Kinetics of Agricultural By-product used as feed for Sheep in Trinidad, West Indies

“…Rice hulls may also be affecting the rate of degradability due to its high ber content. Kim et al, (2019), also reported that due to the high ber content digestibility in sheep was affected. This shows that the chemical composition of ingredients has varying effects on ruminal fermentation.…”

Food Security: Nutritional Characteristics, Feed Utilization Status and Limiting Factors of Aged Brown Rice

“…Because of the high grain content in dairy cow diets, replacing corn with rice in the diet of cows resulted in an increase in rumen starch digestibility, the dry ma er and starch intake decreased. The report of Kim et al [67] concluded that the maximum amount of paddy replacing corn in the sheep diet cannot exceed 91%. Ca elam et al [68] found that brown rice can reduce carcass weight, adipose tissue accumulation, and slaughtering performance of ca le compared with maize, indicating that it is not suitable to feed brown rice during ca le's growth and fa ening stages.…”
