The influence of the mixture of some plant powder with Anacardium occidentale shell liquid smoke on total bacteria and Escherichia coli in the ileum of broiler

Antibiotics/feed additives are commonly used in poultry rations to prevent disease, increase feed efficiency, and improve performance. Plants are the alternatives to replace antibiotics that are safe and without side effects for chicken meat consumers. The aim of this study was to evaluate the effect of administration of a mixture of plant powder and Anacardium occidentale shell liquid smoke on the total bacteria and Escherichia coli in the broiler ileum. The plant mixture was: Phyllanthus niruri L. (PNP) powder: Anacardium occidentale shell liquid smoke (AOLS): Syzygium aromaticum leaf powder (SAP). The study used a Completely Randomized Design. In total, 80 one-day-old broiler chicks were allotted randomly into eight treatments with two replicates per treatment and 5 birds per replicate. The study with the following treatments: Control, Zn-Bacitracin 0.05%, T1 (1.25%: 0.125%: 0.313%), T2 (1.25%: 0.125%: 0.157%), T3 (0.625%: 0.125%: 0.157%). T4 (0.625%: 0.0625: 0.157%), T5 (0.313%: 0.0313: 0.625%), T6 (0.313%: 0.125%: 0.313%). To find out the total bacteria and Escherichia coli, the chicken is then slaughtered 2 hens per replicates to collect feces from the ileum. The results showed that the treatment of the mixture of PNP: AOLS: SAP was not significantly different (P>0.05) with Zn-bacitracin treatment on the total bacteria and Escherichia coli. However, the number of bacteria in T1 was lower than that of the Zn-bacitracin treatment, while the number of Escherichia coli in T1 was closer to the Zn-bacitracin treatment. It can be concluded that the PNP: AOLS: SAP (1.25%: 0.125%: 0.313%) mixture at T1 treatment has the potential as a natural antibiotic to replace Zn-bacitracin antibiotic in inhibiting total growth of bacteria and Escherichia coli in the ileum of broiler.

In Vitro and In Vivo Evaluation of the Effects of a Compound Based on Plants, Yeast and Trace Elements on the Ruminal Function of Dairy Cows

The high production levels reached by the dairy sector need adjustment in nutritional inputs and efficient feed conversion. In this context, we evaluated a compound (QY—Qualix Yellow) combining optimized inputs in trace elements and 20% MIX 3.0. In a first step, the effects of MIX 3.0 on ruminal function were assessed in vitro by incubating ruminal fluid with the mixture at a ratio of 20:1. The results obtained encouraged us to test QY in vivo, on a herd of dairy cows. The herd was divided into one group of 19 dairy cows receiving the compound and a control group of 20 animals conducted in the same conditions, but which did not received the compound; the production performance and feed efficiency of the two groups were compared. In vitro experiments showed improved digestion of acid and neutral detergent fibres by 10%. The propionate production was enhanced by 14.5% after 6 h incubation with MIX 3.0. The plant mixture decreased the production of methane and ammonia by 37% and 52%, respectively, and reduced the number of protozoa by 50%. An increase in milk yield by 2.4 kg/cow/d (p < 0.1), combined with a decrease in concentrate consumption of 0.27 kg DM/cow/d (p < 0.001), was observed in vivo after consumption of the compound. Sixty-six days after the beginning of the trial, methane emissions per kg of milk were significantly lower in the group receiving QY. In conclusion, MIX 3.0 induced change in ruminal function in vitro and, when it entered into the composition of the QY, it appeared to improve feed efficiency and production performance in vivo.

Effect of Forage Plant Mixture and Biostimulants Application on the Yield, Changes of Botanical Composition, and Microbiological Soil Activity

Recently, an increasing interest in such fertilizers and fertilization methods which not only directly supply nutrients to plants, but also stimulate soil bioactivity is noted. Their effect on both soil microbiota and forage plants has not been fully recognized. The aim of the study was to investigate the combined effect of forage plant mixture type and mineral fertilizers (NPK) with biostimulants based on a marine algae extracts on the botanical composition, yield, the structure of selected taxonomic and trophic groups of soil microorganisms, and the soil enzymatic activity. During the years 2018–2019 a field experiment established in split-plot design with two different forage plant mixtures, as a first factor, and different fertilization basing on mineral fertilizers amended with biostimulants, as a second factor was conducted. Two types of forage mixtures of sown species were used: grass mixture (GM) and legume-grass mixture (LGM). Every year the following biostimulants were applied: N-14, PinKstart, Physiostart, Physioactive and they were compared with standard NPK fertilisation and no fertilisation as a control. The reaction of forage plant mixtures on applied fertilisation was different. The intensive development of grass species, mainly Lolium perenne, at the expense of Trifolium repens share in LGM was observed. In GM sward dominated Dactylis glomerata. A beneficial effects of biostimulants’ application on the biomass yields of both grass mixtures was observed. The systematic soil acidification and a decrease of soil enzymatic activity in result of applied fertilization, except NPK + Physioactive treatment (calcium fertilizer containing 76% calcium carbonate), was noted. Soil reaction to applied fertilisation was dependent on the botanical composition of the sward. The counts of microorganisms in the soil under LGM were almost two times higher than in the soil under GM. The most effective, in reducing the negative effect of nitrogen mineral fertilization on the pH of soil, was fertilization with NPK + Physioactiv.

Medicinal Animals and Plants as Alternative and Complementary Medicine in Southern Regions of Khyber Pakhtunkhwa, Pakistan

Background: Local communities use animals and plants as common traditional therapies for various diseases. The study aimed to document animals and animal-plant mixture recipes that are used as alternative and complementary medicine in southern regions of Khyber Pakhtunkhwa, Pakistan.Methods: The data were collected (2017–2018) in three remote areas (Dera Ismail Khan, Bannu, and Lakki Marwat) through questionnaires and face-to-face interviews with local inhabitants. Data on ethnomedicinal uses and cultural values of animal products or parts and their mixture with plants were analyzed using various indices such as frequency of citation (FC), informant consensus (FIC), and fidelity level (FL) to find the highly preferred species in the area.Results: A total of 185 informants (117 females and 68 males) were interviewed. The study documented 32 animal species, vertebrates (n = 24) and invertebrates (n = 8), for curing 37 types of diseases. Mammals (n = 13) were among the most commonly utilized species followed by birds (n = 8), arthropods (n = 7), reptiles (n = 2), and fishes and annelids (n = 1 each). Among the reported animals, Herpestes edwardsi (mongoose), Macaca mulatta (monkey), Labeo rohita (rohu), Oryctolagus cuniculus (rabbit), and Streptopelia decaocto (dove) were the newly reported species used as alternative medicine. The meat of Capra hircus (goat), monkey, and rabbit was used to treat chronic diseases such as hepatitis C, cancer, epilepsy, and asthma. A total of 17 plants belonging to 15 botanical families were used in combination with animal parts/products. The commonly used families were Piperaceae (31%) followed by Apiaceae (27%). The notable plant species in combination with animal products were Curcuma longa, Piper nigrum, Coriandrum sativum, Brassica rapa, and Phoenix dactylifera. Seeds were the highest used part in animal-plant mixture recipes. Gallus gallus (chicken) and Columba livia (pigeon) secured the highest (FC = 28) and (FL = 80%), respectively. FIC results had shown the highest degree of consensus for general body weakness (FIC = 0.88) and pyrexia (FIC = 0.86).Conclusion: Our findings suggest that local communities in the southern regions of Khyber Pakhtunkhwa have substantial knowledge about the formulation of ethnomedicines from both flora and fauna that need urgent documentation to avoid eroding and for conservational purposes. The newly reported phytozootherapeutic recipes and animal species can potentially be a source of pharmacologically active constituents and should be checked experimentally for further confirmation.

Interactions between Plants and Plant-Soil in Functionally Complex Mixtures Including Grass Pea, Faba Bean and Niger, Intercropped with Oilseed Rape

Winter oilseed rape (OSR) can be grown intercropped with frost-sensitive service plant mixtures. This practice may reduce weed pressure and contribute to providing N for OSR after service plant freezing. However, there is little knowledge of how plants interact together and with the soil in diverse annual crop mixtures. To assess these interactions, two contrasting legume service plants were selected: faba bean and grass pea, as well as a non-legume, the niger plant. OSR and the legumes were then grown in mesocosms alone or intercropped in mixtures of two to four species. The biomass, N contents, N2 fixation, and soil substrate-induced respiration were measured. A single species mostly drove the total dry biomass and the amount of N accumulated by the cover, OSR and faba bean for dry weight and N contents, respectively. Grass pea was highly sensitive to competition with OSR, and its N2 fixation was lower than that of faba bean. The addition of niger did not lead to additional N2 fixation of legumes or total N accumulation and contributed to reducing OSR biomass. The specific composition of the plant mixture did not explain the soil microorganism activity.

Effects of medicinal plants mixture on growth performance, nutrient digestibility, blood profiles, and fecal microbiota in growing pigs

Background and Aim: Alternative natural materials to antibiotics for improving digestive health and growth performance are needed due to strengthening regulations related to the use of antibiotic growth promoters. The study aimed to evaluate the effects of medicinal plants mixture (60% Bidens pilosa L., 15% Urena lobata L., 15% Pseuderanthemum palatiferum, 5% Ramulus cinnamomi, and 5% Star anise) as alternative growth promotors on animal health, nutrient digestibility, blood parameters, and growth performance of growing pigs. Materials and Methods: The study was conducted, from April 2020 to June 2020, at a private pig production farm located in Cam Giang district Hai Duong Province, Vietnam. Forty-eight 10-week-old crossbred (♂Duroc×♀ [Landrace×Yorkshire]) pigs, average initial body weight 30.3±1.42 kg, were randomly allocated to four dietary groups, three replicate pens per experimental group, with 4 pigs/pen. For 7 weeks, the pigs were fed a basal diet supplemented with the mixture at levels of 0, 20, 40, and 60 g/kg of feed. Results: Final body weight, average daily gain, average daily feed intake, and feed conversion ratio, as well as apparent total tract digestibility of dry matter, organic matter, crude protein, ether extract, and gross energy were not significantly influenced by the diets (p>0.05). Inclusion of the plant mixture decreased significantly red blood cell count, blood cholesterol, urea nitrogen, and low-density lipoprotein (LDL) concentrations (p<0.05) compared with the control diet. No diet effect was observed on fecal Escherichia coli, Salmonella spp., Clostridium spp., and total bacteria counts. Conclusion: The incorporation of the plant mixture into the diet of growing pigs reduced serum cholesterol, LDL, and urea concentrations with no adverse effect on performance and nutrient digestibility.

Determination of amino acids content in two samples of the plant mixtures by GC-MS

Due to the wide range of biologically active substances, the plant mixtures can influence the development of diabetes mellitus and its complications. Amino acids attract particular attention due to their ability to stimulate insulin secretion, reduce hyperglycemia and regulate metabolic processes in patients with diabetes. The aim of this study was to investigate the content of amino acids in the plant mixture samples: 1) Cichorium intybus roots, Elymus repens rhizome, Helichrysum arenarium flowers, Rosa majalis fruits, Zea mays columns with stigmas, 2) Urtica dioica leaf, Taraxacum officinale roots, Vaccinium myrtillus leaf, Rosa majalis fruits, Mentha piperita herb, which have proven antidiabetic activity in studies in vivo. The amino acids were separated by validated method of gas chromatography-mass spectrometry with pre-column derivatisation. Quantitative analyses of amino acids showed that the predominant components were L-proline in the sample 1 and L-leucine and L-proline in the sample 2 of the plant mixtures.
