Abstract
This study was implemented to assess the effect of Pinus koraiensis extract (PKE) compared with zinc oxide on growth performance, nutrient digestibility, blood profile, fecal bacterial count, and fecal gas emission of post-weaned pigs. This 6 wk experiment was divided into phase 1 (days 1–7), phase 2 (days 8–21), and phase 3 (days 22–42). A total of 150 crossbred weaning pigs (body weight; 10.14 ± 0.78 kg) were randomly sorted in five treatment diets (six replications per treatment; five pigs per pen) presented as CON, basal diet; ZnO, CON + 0.30% zinc oxide; PKE1, CON + 0.05% PKE; PKE2, CON + 0.10% PKE; and PKE3, CON + 0.15% PKE. Pinus koraiensis extract supplementation linearly reduced gain to feed ratio in all phases except phase 3. It also linearly increased average daily gain in the overall experiment compared with the CON group. The increasing level of PKE supplementation brought linear improvement in aspartate aminotransferase of blood profile. Escherichia coli bacterial count and NH3 gas emission were decreased linearly by PKE supplementation in comparison to the CON diet. Though PKE supplementation did not show similar influence as ZnO, it showed beneficial results in weaning pigs’ growth, nutrient digestibility, fecal bacterial count, and reduction of fecal gas emission.

Effects of Replacing Medical Zinc Oxide with Different Ratios of Inorganic: Organic Zinc or Reducing Crude Protein Diet with Mixed Feed Additives in Weaned Piglet Diets. Animals (Basel) 2021; 11:3132. [PMID: 34827863 PMCID: PMC8614496 DOI: 10.3390/ani11113132] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 10/27/2021] [Accepted: 10/29/2021] [Indexed: 11/16/2022] Open
Abstract
One hundred twenty weaned piglets (9.34 ± 0.74 kg) were used in a four-week experiment to investigate the effects of replacing medical ZnO with a different ratio of inorganic and organic zinc (IZ:OZ) or a low-crude-protein diet (LP) with mixed feed additives (MFAs) in the weaned piglets' diet. The dietary treatments included a control (CON), T1 (T1; ZnO 1000 mg/kg), T2 (IZ:OZ 850:150), T3 (IZ:OZ 700:300), T4 (IZ:OZ, 500:500), and T5 (LP with MFAs (0.1% essential oils + 0.08% protease + 0.02% xylanase)). The growth performance was decreased (p < 0.05) in the CON treatment compared with the T4 treatment. The diarrhea incidence was decreased (p < 0.05) in the T4 and the T5 treatment compared with the CON and the T1 treatments. The apparent total tract digestibility (ATTD) of nutrients were increased (p < 0.05) in the T4 and T5 treatments compared with the CON, T1, and T2 treatments. The T4 treatment had a higher (p < 0.05) ATTD of zinc than the T1, T2, and T3 treatments. The fecal microflora was improved (p < 0.05) in the T5 treatment compared with the CON and T3 treatments. In conclusion, IZ:OZ 500:500 could improve growth performance, nutrient digestibility, and zinc utilization while reducing diarrhea incidence in weaned piglets. Moreover, LP with MFA could replace medical ZnO.

Abstract
Painful conditions are among the leading causes of years lived with disability, and may increase following the coronavirus pandemic, which has led to temporary closure of some healthcare services for people with chronic pain. To reduce this burden, novel, cost-effective and accessible interventions are required. We propose that greenspace exposure may be one such intervention. Drawing on evidence from neuroscience, physiology, microbiology, and psychology, we articulate how and why exposure to greenspaces could improve pain outcomes and reduce the high global burden of pain. Greenspace exposure potentially provides opportunities to benefit from known or proposed health-enhancing components of nature, such as environmental microbiomes, phytoncides, negative air ions, sunlight, and the sights and sounds of nature itself. We review the established and potential links between these specific exposures and pain outcomes. While further research is required to determine possible causal links between greenspace exposure and pain outcomes, we suggest that there is already sufficient evidence to help reduce the global burden of pain by improving access and exposure to quality greenspaces.
