Evaluation of barley to replace milk by-product in weaning pig’s diet

Abstract

The supplementation level of barley was limited because of high contents of fiber in monogastric animals. Barley contained high soluble fiber, thus it could prevent to diarrhea of weaning pigs. Moreover, as the barley break down by enzymes, free sugars come out from the barley, which could be used as an energy source in weaning pigs and replace milk by-products in weaning pig’s diet. Therefore, present study was conducted to investigate the influence of barley to replace milk by-product in weaning pig’s diet on growth performance, blood profile, nutrient digestibility, diarrhea incidence, and economic analysis in weaning pigs. A total of 112 crossbred ([York-shire × Landrace] × Duroc, weaned at 28 days of age) piglets were allotted to 4 treatments in a randomized complete block (RCB) design. Each treatment has 7 replications with 4 pigs per pen. Pigs were fed each treatment diet which containing different levels of barley (0%, 10%, 20%, and 30%) at the expense of whey powder and lactose. Three phase feeding programs were used for 6 weeks of growth trial (phase 1: 0–2 weeks; phase 2: 3–4 weeks; phase 3: 5–6 weeks). During 0–2 week, body weight (BW), average daily gain (ADG) and G:F ratio were decreased as barley level increased in the diet (linear response, p < 0.01). In blood profile, blood urea nitrogen was decreased as the barley level increased in the diet (linear, p < 0.01). However, no significant differences were observed in blood glucose level. In nutrient digestibility, crude fat digestibility was linearly increased as barley increased (linear, p < 0.01). The incidence of diarrhea was improved as increasing barley contents in all phases (linear, p < 0.01). These results demonstrated that supplementation of barley to replace milk by-product influenced negatively on growth performance during 0–2 week. However, the incidence of diarrhea and later growth performance from 3 week postweaning were improved as dietary barley level increased.

Influence of various levels of milk by-products in weaner diets on growth performance, blood urea nitrogen, diarrhea incidence, and pork quality of weaning to finishing pigs

“…Also, barley has relatively high fiber source which reduced diarrhea occurrence and is helpful in preventing diarrhea [ 26 ]. Also, Jin [ 7 ] demonstrated that supplement of barley in weaning pig diet reduced the incidence of diarrhea. Due to the effect of ZnO and barley, weaning pigs fed no or low milk by-product had no significant difference in diarrhea incidence compared with pigs fed high milk by-product content.…”

“…Recently, Jin [ 7 ] reported an evaluation of supplementation with barley instead of milk by-products in weaning pig’s diet. This demonstrated that barley replacing milk by-product caused low growth performance during the weaning period.…”

Effect of Different Amounts of Hybrid Barley in Diets on the Growth Performance and Selected Biochemical Parameters of Blood Serum Characterizing Health Status in Fattening Pigs

“…Our study did not confirm reduction of serum glucose level. Additionally, β-glucan supplementation resulted in a lower number of pathogens found in liver what can be related with reduced intestinal translocation of bacteria [52].…”

Meta-analysis of relationship between weaning age and daily weight gain of piglets in the farrowing and nursery phases

“…The papers that both assessors assessed affirmatively for all questions were included in the analysis, yielding 28 papers. These articles were Nielsen et al (2001), Houška et al (2004, Wellock et al (2008), Li et al (2008), Kutzer et al (2009), Zonderland et al (2010), Fels et al (2012, Madsen & Bee (2014), Bell et al (2015), Baldinger et al (2016), Van Wettere et al (2016, Almeida et al (2017), Vanrolleghem et al (2019, Montsho et al (2016), Kalita et al (2015), Jin et al (2019), Tsourgianis et al (2004, Devillers and Farmer (2009), Bohnenkamp et al (2013) Using Excel® software, the data regarding the impact of weaning age on piglet performance were organized for statistical analysis. The variables were tested for normality of the residuals using Shapiro-Wilk test and homogeneity of variance using Levene's test.…”
