Evaluation of brown rice to replace corn in weanling pig diet

Abstract

This study was conducted to evaluate the effects of brown rice (Japonica) on growth performance, nutrient digestibility, and blood parameters of weanling pigs. A total of 60 weanling pigs (28-day-old, 30 barrows and 30 gilts, 6.73 ± 0.77 kg body weight [BW]) were randomly allotted to 2 dietary treatments (6 pigs per pen; 5 replicates per treatment) in a randomized complete block design with the initial BW and sex as blocks. The dietary treatments were a typical nursery diet based on corn and soybean meal (CON) and the CON replaced 50% of corn with brown rice (BR). Pigs were fed respective dietary treatments for 5 weeks. For the last week of experiment period, pigs were fed respective dietary treatments containing 0.2% chromic oxide as an indigestible marker. Fecal samples were collected from randomly selected 1 pig in each pen daily for the last 3 d after the 4-d adjustment period.Blood was collected from randomly selected 1 pig in each pen on d 0, 3, 7, and 14 after weaning. Compared with pig fed CON diet, pigs fed the BR diet were found to have higher (p < 0.05) final BW, overall average daily gain, and apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of dry matter and energy.However, there were no significant differences between the groups with respect to average daily feed intake, gain to feed ratio, frequency of diarrhea, and the AID and ATTD of crude protein during overall experimental period.Similarly, there were no significant differences on blood parameters between the groups. Thus, the findings of this study indicate that brown rice (Japonica) can be used to replace 50% of corn in the diet of pigs during the nursery period without negatively affecting growth performance, nutrient digestibility, or blood parameters.

Effects of adding bile acids to dietary storage japonica brown rice on growth performance, meat quality, and intestinal microbiota of growing–finishing Min pigs

“…However, it had a good effect on cost reduction and efficiency in animal production ( 23 ). Nevertheless, studies have shown that feeding weaned piglets with brown rice as a 50% substitute for corn resulted in an increase of 2.43 and 2.88% in apparent ileal digestibility of dry matter and energy compared to the control group, respectively ( 24 ). The reasons for the different results may be attributed to the different growth stages of the experimental animals selected by researchers, as well as the differences in the storage time of brown rice.…”

An Evaluation of Paddy Rice as an Alternative Energy Source in Protein-Restricted Diets for Growing, Early-Finishing, and Late-Finishing Pigs

“…Additionally, the use of fibrous diets may increase the thickness of the unstirred water layer adjacent to gut mucosa, leading to impaired nutrient utilization [24]. A previous study also demonstrated that a high fiber content might form a physical barrier to block enzymes' access to starch granules to restrain starch hydrolysis [25]. Moreover, increased dietary fiber is able to adsorb amino acids (AAs) and peptides, withholding them from digestion, and hence limiting AAs' availability for protein deposition in growing pigs [26].…”

A bi-functional three-terminal memristor applicable as an artificial synapse and neuron

“…in which the C 1 and C 2 are initial facilitation magnitudes, τ 1 and τ 2 are the fitted time constants. 42,43 The decay process can be divided into two coupling phases: a rapid phase with a short relaxation time constant (τ 1 = 33 ms) and a subsequent slow phase with a large time constant (τ 2 = 774 ms), [44][45][46] which are commensurate in scale with that observed in biological synapses. 47 We further demonstrate high-pass dynamics filtering using the STP properties of the device by applying multiple gate pulses with varying frequencies.…”
