“…Dietary supplementation of 100 or 200 mg/kg PNE also significantly improved the yolk weight. This may have been because the PNE promoted hepatic lipid metabolism by protecting hepatocytes from oxidative damage, thus enhancing the yolk weight ( 19 ), which is consistent with the results of a previous study ( 20 ). The observed improvements in egg mass and feed efficiency after PNE supplementation might have been due to the presence of essential oils, terpenoids, and polyphenols, which are reported to improve nutrient digestion, absorption, and utilization in the digestive tract ( 7 , 18 ).…”

The effects of Masson pine (Pinus massoniana Lamb.) needle extract (PNE) on gastrointestinal disorders and oxidative stress have been widely investigated using experimental models; however, the functions and mechanisms of these effects in chicken models remain unknown. We investigated the effects of Masson PNE supplementation on performance, egg quality, serum parameters, and the gut microbiome in laying hens. A total of 60 healthy 50-week-old Peking Pink laying hens with similar body conditions and egg production were randomly divided into the control (CON) (0 mg/kg PNE), PNE100 (100 mg/kg PNE), PNE200 (200 mg/kg PNE), and PNE400 (400 mg/kg PNE) groups, with fifteen replicates per treatment and one hen per replicate. Compared with the CON group, egg mass, feed conversion ratios, and yolk weight were significantly increased (p < 0.01) in the PNE100 group. Dietary supplementation of 100 mg/kg PNE increased the serum total protein, albumin, and glucose concentrations (p < 0.01) and decreased the alanine aminotransferase activity (p < 0.05) compared with those of the CONs. Hens in the PNE100 group had reduced serum malondialdehyde levels (p < 0.05) and increased catalase, superoxide dismutase, and glutathione peroxidase activities (p < 0.01) compared with those of the CON group. Serum proinflammatory cytokine concentrations of interleukin (IL)-1β, IL-6, and tumor necrosis factor-α were lower (p < 0.01) and the IL-10 level was higher (p < 0.01) in the PNE100 group than in the CON group. Serum immunoglobulin (Ig)A, IgG, and IgM concentrations were increased in the PNE100 group (p < 0.01). The relative abundance of Bacteroidetes was increased, while the relative abundances of Firmicutes and Proteobacteria were decreased in the PNE100 group. The relative abundances of Vibrio, Shewanella, and Lactobacillus were decreased, while the relative abundances of unclassified_o_Bacteroidales, Rikenellaceae_RC9_gut_group, unclassified_f_Rikenellaceae, and Butyricicoccaceae were increased in the PNE100 group compared with those of the CON group. PNE supplementation at 100 mg/kg improved the diversity and structure of the gut microbial composition, production performance, egg quality, and serum parameters of laying hens. The laying hens in this study had good production performance when supplemented with 100 mg/kg PNE.

This study was conducted to investigate the effect of feeding colored barley (CB) and whole crop barley (WCB) on performance, egg quality and blood composition of laying hens. A total of 280, 35 weeks old Brown Nick laying hens were allocated into the individual cage for the period of four weeks. Experimental diets contained 2,750 kcal/kg ME and 16% CP, respectively. The treatments consisted of 5, 10, 15% CB and WCB as feed ingredients with control and there were five replications in each treatment. Higher egg production was noticed at 10% level of CB and 5% level of WCB in the diets, respectively. Feed intake was higher in WCB and CB treatments compared to those of the control (P<0.05), but the feed conversion was not different. Yolk color tended to increase both in WCB and CB groups. Haugh unit seemed to increase WCB treatments. When the CB and WCB were fed at 15% level, blood total proteins, albumin, total cholesterol and triglyceride contents were decreased than that of the control birds, but total cholesterol and HDL-cholesterol tended to be higher with the increasing level of WCB. As results, no significant differences were observed in performance and egg quality with different levels of dietary WCB and CB. Thus, CB and WCB can be substituted as a feed ingredient up to 15% level in the laying hens' diet. However, further studies are required by feeding more than 15% levels of CB and WCB in the diet of laying hens.

“…Using pine tree byproducts as mulch presents sustainable farming opportunities [11,13]. Crushed pinecones exhibit beneficial properties, including antifungal attributes, and have been explored by researchers for potential use in livestock [15,16] and cosmetics [17][18][19][20]. Abundant post-pine-nut harvesting, pinecones emerge as an economical mulching option in Gangwon-do, a prominent pine-nut-producing region in Korea.…”

While crushed pinecone mulch holds promise as a beneficial material for blueberry cultivation, research on its effectiveness remains limited. Crop leaf characteristics can serve as parameters for assessing mulching effects, although there are several limitations, including the need to analyze various distinct characteristics separately. The combination of hyperspectral data and machine learning techniques is expected to enable the selection of only the most important features among these characteristics. In this study, we investigated the impact of various mulching treatments utilizing pine tree byproducts, including crushed pinecones. Mulching variations included non-mulching (NM), crushed pinecones (PCs), a mixture of crushed pinecones and sulfur (PCS), pine needles (PNs), and sulfur treatment (S). Conventional methods were employed to measure leaf growth (length and width) and physiological characteristics (chlorophyll content, chlorophyll fluorescence, and stomatal conductance). Hyperspectral reflectance was also measured, and classification models using Partial Least Squares Discriminant Analysis (PLS-DA) and eXtreme Gradient Boosting (XGBoost) were developed for crop characteristics, vegetation indices (VIs), visible and near-infrared (VNIR), and short-wave infrared (SWIR). The results showed that using crushed pinecones as the sole mulching material for blueberries, without sulfur treatment, had a positive impact on blueberry growth. The PC treatment exhibited a dual effect on plant growth by lowering the soil pH to 5.89 and maintaining soil moisture within the range of 26.33–35.20%. We observed distinct differences in soil inorganic nutrient content, with higher concentrations of organic matter, total nitrogen, and available P2O5 and K+, which positively influenced blueberry growth. Mulching treatments demonstrated superior physiological characteristics, with two classification models identifying stomatal conductance (gs) as a key parameter influencing treatment classification (VIP scores > 1 rank: 3, variable score rank: 1). The photochemical reflectance index (PRI) emerged as a major parameter among VIs, showing potential for measuring water stress (VIP scores > 1 rank: 2, variable score rank: 1). In the SWIR PLS-DA model, wavelength peaks were mainly observed in the O-H overtone (1410 nm, 1450 nm, 1930 nm, 1940 nm, and 2100 nm). Overall, crushed pinecones were found to positively impact the initial growth of blueberries by enhancing water status (plant respiration).
