“…There is widespread interest in developing non-conventional feedstuffs to replace concentrates ( Wang et al, 2007 ; Lodge-Ivey et al, 2014 ). Wang et al (2007) reported that Porphyra haitanensis (a species of algae) could be used as a protein source in ruminant diets. It has also been found that diets including 20% Ulva lactuca were not refused by ruminants ( Arieli et al, 1993 ).…”

The objective of the present study was to determine the effects of feeding pelletized broccoli byproducts (PBB) on milk yield and milk composition in dairy cows. In Trial 1, an in vitro gas test determined the optimal replacement level of PBB in a concentrate mixture in a mixed substrate with Chinese wild ryegrass hay (50:50, w/w) at levels of 0, 10%, 20%, 30%, or 40% (dry matter basis). When the concentrate was replaced by PBB at a level of 20%, no adverse effects were found on the gas volume or its rate constant during ruminal fermentation. In trial 2, 24 lactating cows (days in milk = 170.4±35; milk yield = 30±3 kg/d; body weight = 580 ±13 kg) were divided into 12 blocks based on day in milk and milk yield and randomly allocated to two dietary treatments: a basic diet with or without PBB replacing 20% of the concentrate mixture. The feeding trial lasted for 56 days; the first week allowed for adaptation to the diet. The milk composition was analyzed once a week. No significant difference in milk yield was observed between the two groups (23.5 vs 24.2 kg). A significant increase was found in milk fat content in the PBB group (p<0.05). Inclusion of PBB did not affect milk protein, lactose, total solids or solids-not-fat (p>0.05). These results indicated that PBB could be included in dairy cattle diets at a suitable level to replace concentrate mixture without any adverse effects on dairy performance.

“…22 MMT is one type of representative clay adsorbent for treating pig enteric diseases. However, while some studies report MMT to be effective in promoting growth performance, intestinal morphology, 23 benecial bacteria, 24 reducing the diarrhea rate and inhibiting harmful bacterial strains, other studies report no improvements in pig performance as a result of feeding with MMT. 23,25 Many plants can be prepared as activated charcoal.…”

“…Clay as MMT has been reported to increase the numbers of benecial bacteria such as Bidobacteria and Lactobacillus and decrease the proportion of harmful bacteria such as Clostridium and E. coli in the small intestine 23,24 in weaned pigs. In our study, CHC decreased the numbers of E. coli in the cecum at a dose of 500 mg kg À1 .…”

This study was conducted to evaluate the effects of activated charcoal-herb extractum complex (CHC) on the growth performance, immunological indices, intestinal morphology and microflora in weaning piglets to determine the optimal supplemental dose. A total of 216 weaned piglets (Duroc Â Landrace Â Large White) with an initial body weight of 8.55 AE 1.18 kg were randomly assigned to six treatment groups; each treatment group had six pens, with six pigs per pen. The study period was 28 d. Pigs were fed a corn-soybean meal-based diet supplemented with 500, 1000, 1500 or 2000 mg kg À1 of CHC over two 14-d periods. Two additional diets containing 0 and 1000 mg kg À1 of montmorillonite were set as the negative and positive controls, respectively. Supplementation with 500 mg kg À1 of CHC significantly increased average daily gain compared with the positive and negative controls during phase I and the entire experimental period (P < 0.05). During phase I, 500 and 1000 mg kg À1 of CHC significantly decreased diarrhea incidence compared with the negative control, and increased serum IGF-1 and serum IgM levels compared with the controls (P < 0.05). CHC at 500 mg kg À1 significantly decreased the diarrhea score during the entire experimental period compared with the negative control (P < 0.05). On day 28, supplementation with 500 and 1000 mg kg À1 of CHC increased serum IgG, IL-1b, and duodenum and jejunum secretory IgA compared with the negative control and decreased duodenum and jejunum MDA levels compared with the controls (P < 0.05). Increased duodenum and jejunum villus height and an increased ratio of villus height to crypt depth were observed compared with the negative control and decreased viable counts of E. coli in the cecum were detected compared with the controls (P < 0.05). Collectively, the optimal dose of CHC was found to be 500 to 1000 mg kg À1 in this study.Means within the same row without common superscripts differ signicantly (P < 0.05). b IgM immune globulin M, IgA immune globulin A, IgG immune globulin G, IL-1b interleukin-1b, IFN-g interferon-g.5952 | RSC Adv., 2019,9,[5948][5949][5950][5951][5952][5953][5954][5955][5956][5957] This journal is
