Evaluating agro-industrial by-products as dietary roughage source on growth performance of fattening steers

Abstract

Silages from pineapple peel, sweet corn husk and cob mixed with bagasse and vinasse were evaluated to determine their chemical composition and fermentation characteristics as well as feeding performance in fattening steers. The experiment, which lasted 90 days, involved 48 fattening steers (264 ± 37.4 kg BW) randomly allocated to three diets. Treatments included: a control diet containing rice straw and molasses (T1); diet containing bagasse-vinasse mixture including sweet corn husk and cob silage (BS; T2); and diet containing bagasse-vinasse mixture including pineapple peel silage (BP; T3). All treatments included a commercial concentrate feed (13% CP) and ad libitum rice straw throughout the experiment. Results from chemical analysis showed that dry matter (DM) of BS was higher than BP (P < 0.05), whereas the protein content of BS and BP was similar (P> 0.05). For fermentation characteristics, pH in BP was lower than BS (P < 0.05); in addition, acetic and butyric acids in BS were higher than BP (P < 0.05). Findings from growth trial showed that total DM intake in steers fed T1 was higher compared to the other dietary treatments (P < 0.05), whereas the average BW gain was found to be grater in T3 steers (P < 0.05). As result from our findings, bagasse-vinasse mixture with pineapple peel silage appeared to be a viable feed ingredient in fattening steer diet and moreover it could become an economically feasible agro-industrial by-product for farmers.

The effect of vinasse on the growth performance and feed digestibility of Holstein male calves

“…Kemenade, den Hartog, Haaksma, and Verstegen (1988) obtained similar results which showed the feed intake of bull calves and broilers increases by vinasse addition and this consequently causes a greater average daily weight gain in these animals (Kemenade et al, 1988). But Maneerat, Prasanpanich, Tumwasorn, Laudadio, and Tufarelli (2015) have shown reduction in feed intake in steers fed by bassagevinasse compared with molasses. Also, Zali, Eftekhari, Fatehi, and Ganjkhanlou (2017) have reported higher live slaughter weight in Holstein male calves fed with diet containing 5% vinasse.…”

Pineapple stem by-product as a feed source for growth performance, ruminal fermentation, carcass and meat quality of Holstein steers

“…Thus Holstein steers fed pTMR diet received a more high-energy diet than steers fed nTMR and cTMR. Accordingly, Maneerat et al (2015) found that steers (Brahman × Thai) fed pineapple peel silage mixed with bagasse and vinasse (BP) exhibited the highest ADG level related to the NFE and gross energy of pineapple silage compared with sweet corn silage. Although CP in the pTMR diet was lower than in the cTMR diet, the levels of CP in the TMR diets had no effect on growth performance in the feedlot stage (Boonsaen et al, 2007).…”

“…Besides, researchers have focused on the performance and the apparent digestibility of pineapple byproduct when used as feed. Previous studies reported that Brahman × Thai steers fed silage from pineapple peel mixed with bagasse and vinasse led to increased gross energy and a higher average daily gain (ADG) compared with sweet corn husks and cob silage mixed with bagasse and vinasse (Maneerat et al, 2015). Additionally, Zainuddin et al (2014) found that the by-product from pineapple stems contained high levels of crude fibre (CF) (average 39.75%) and carbohydrate (average 41.92%), but there was no report of feeding pineapple stems to feedlot cattle.…”

“…Sheep fed with pineapple peel‐added silage during 90 days showed an increase in body weight, which suggested that pineapple peels might be an economically feasible agro‐industrial byproduct for farmers (Maneerat, Prasanpanich, Tumwasorn, Laudadio, & Tufarelli, ).…”
