[PMID: 38027706 PMCID: PMC10663850 DOI: 10.1016/j.heliyon.2023.e21649] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 09/20/2023] [Accepted: 10/25/2023] [Indexed: 12/01/2023] Open
Abstract
This investigation was conducted to evaluate pod and chemical component traits and the genetic diversity of Prosopis juliflora genotypes at two locations. The selected locations were in the middle (Qassim region) and western (Jeddah region) areas, representing two agro-climatic zones of Saudi Arabia. The measured pod characteristics included production, weight, length, filling period, and chemical composition. A wide range of variations in pod yield and chemical traits were observed in the different agro-climatic regions. The results revealed that the mean values ranged from 9.5 kg tree-1 (Jeddah) to 14.2 kg tree-1 (Qassim) for pod yield, 3.1 g pod-1 (Qassim) to 3.7 g pod-1 (Jeddah) for pod weight, and 14.8 cm (Qassim) to 16.6 cm (Jiddah) for pod length. The results of genetic diversity indicated that Prosopis genotypes in each location were distributed in three different clusters in the two regions at 60 Euclidean distances. The principal component analysis (PCA) showed that the two components (PC1 and PC2) explained 25.03 % and 20.03 % of the overall variance, respectively, which is over 45 % of the variability. The heatmap revealed that genotypes Q20, Q21, and Q24 at the Qassim location and genotypes J1, J6, and J7 at the Jiddah location exhibited positive and significant correlations with pod yield. It can be concluded that superior Prosopis genotypes (Q20, Q21, Q24, J1, J6, and J7) were identified with good traits (pod yield, pod-filling period, and protein %) in each location and may be used in the future for the selection of elite genotypes.

Abstract
Mesquite (Prosopis L.) is considered an invasive browse species in most of the American Southwest. Mechanical intervention removes yields an excess of organic debris. Anecdotal evidence in the past has supported using such browse as feed for livestock. Thus, our objectives were to (1) determine the nutritive value and fermentation characteristics of silage produced with mesquite biomass, and (2) evaluate solvent treatment of mesquite biomass prior to ensiling. In Experiment 1, we evaluated mesquite inclusion rate (0, 250, 500, 750, or 1000 g kg−1 DM), length of fermentation (28, 56, or 84 d), and silage inoculant. In Experiment 2, we evaluated the effects of mesquite pre-treatment with acid (H2SO4) or alkali (NaOH) solutions. Concentrations of NDF, ADF, and ADL, as well as IVTD, decreased (p < 0.05) with increasing mesquite inclusion. However, 250 g mesquite kg−1 DM did not differ from grass silage. There was no effect (p > 0.05) of inoculation, though increasing length of incubation did increase (p < 0.05) VFA production and decrease (p < 0.05) silage pH. Solvent treatment did not improve ensiling properties. Results are interpreted to mean that mesquite biomass may be effectively incorporated into silage at levels up to 250 g kg−1.

Prosopis Species—An Invasive Species and a Potential Source of Browse for Livestock in Semi-Arid Areas of South Africa. SUSTAINABILITY 2021.

Abstract
Globally, there have been differing views on whether the proliferation of invasive species will be of benefit as a livestock feed source or it will have detrimental effects on the ecosystem. The infestation of invasive plants such as Prosopis species does not only affect the groundwater levels but also threatens the grazing capacity and species richness of most of the semi-arid areas around South Africa. Though Prosopis is invasive, it is however of good nutritive value and can serve as an alternative source of protein and minerals for livestock during the dry season. Bush encroachment by browsable invasive species can be controlled through biological methods by using organisms such as livestock. The utilisation of Prosopis through browse benefits livestock production and at the same time reduces its spread, thereby preventing possible environmental harm that may arise. Although several studies have been carried out globally on the assessment of the Prosopis species’ nutritive value and also on the threat of this invasive species to the environment, there is a need to update the state of knowledge on this species, particularly in the context of the semi-arid areas of South Africa where the dry season is characterised by less herbage of poor quality. It is therefore critical to understand whether Prosopis is a beneficial invader, or a detriment that needs to be eradicated. This review will contribute knowledge towards finding practical solutions to controlling Prosopis species and whether utilising Prosopis as a feed source will limit its spread and result in a vegetation structure where Prosopis becomes part of the ecosystem with limited detrimental impact. This means that the several components of the species such as nutritive value and the negative impact associated with this plant species along with the means to control its spreading must be well understood to recognise the plant species’ vital contribution to the ecosystem.

Effect of incorporation of ground Prosopis juliflora pods in layer diet on weight gain, egg production, and natural antibody titer in KALRO genetically improved indigenous chicken. Trop Anim Health Prod 2019; 51:2213-2218.

Abstract
The potential of using Prosopis juliflora pods was evaluated as a partial replacement of energy source layer's diets. The main objective of the experiment was to assess the effect of replacement of Prosopis juliflora pods at 10, 20, and 30% on egg production, weight gain, and natural antibody titer values (IgG and IgM). The diet treatments were formulated (iso-caloric and iso-nitrogenous, 12.8 MJ/kg ME and 16% crude protein, respectively) to meet the nutrient requirement of the indigenous chicken. Sixty-four KALRO-improved indigenous chicken layers of 43 weeks were assigned into four dietary treatments using a completely randomized design. Body weight gain, egg production, and ELISA assay were run to get the data. Data were statistically analyzed using the GLM procedure of SAS. The differences among treatment means were determined using the Tukey's range test. The inclusion of Prosopis juliflora pods in the diets, except at 10%, decreased weight gain and egg production (p < 0.05). The addition of Prosopis juliflora pods had no significant effect on natural IgG and IgM titer values. This study indicated that Prosopis juliflora pods can be included at levels up to 10% in layer diets without affecting egg production and weight gain.

Abstract
Beauveria bassiana is a promising fungus for the biological control of insect pests. The growing costs of conidia production have raised the need to ascertain the efficiency of some low cost substrates. The aim of this study was to analyze the potential use of different raw substrates without nutritional supplement for B. bassiana conidiogenesis. Growth and sporulation were evaluated using 30 g of substrate and 0.3 μL of a conidia suspension (1 x 106 conidia/mL). After 10 days of incubation (70 ± 10% humidity and temperature (T) = 29 ± 1 °C), rice (2.00 x 106 conidia/g substrate), algaroba (2.36 x 106 conidia/g), malt A (1.22 x 106 conidia/g) and malt B (1.75 x 106 conidia/g) showed the highest levels of conidia production. The resulting conidia showed insecticidal activity higher than 80% on coconut termites. These new raw substrates may represent viable alternatives for the production of entomopathogenic fungi for use in the biological control of various insect pests.

Abstract
The present study was initiated with the objective to assess the feeding strategy comprising Prosopis juliflora pods (PJP) in two forms as alternative feed resource for sustainable goat production for dry season in arid areas. Eighteen growing goats (Marwari and Sirohi breed) were distributed into three groups. The roughage offered was similar to all the animals, however, concentrate mixture was standard for the goats of control group (PJP0), whereas, 50 percent ground PJP in PJPG group and 50 percent as such (entire/non-grinded) dried PJP in PJPE group were included by replacing the standard concentrate mixture. The observations on the animals were recorded for a period of seven months. Fifty percent replacement of concentrate mixture from similar to that of the standard concentrate mixture of PJP0 with crushed and entire PJP made diets economical by ₹ 471.50 and 521.50/quintal basis in PJPG and PJPE, respectively. Daily dry matter intake (DMI)/100 kg body weight was 4.53±0.19, 4.68±0.11 and 4.79± 0.17 kg in PJP0, PJPG and PJPE, respectively. The average body weight gain and body condition score of the animals did not differ significantly between the groups. Five goats from all the groups were bred, which became pregnant and delivered kids normally. The results revealed that the feeding of concentrate mixtures containing either 50% ground or entire PJP to the arid goats did not adversely affect growth performance, reproduction and cud chewing. Moreover, the adopted feeding strategy made Prosopis juliflora incorporated concentrate diets more economical than the commercial one.

Abstract
A study with finishing lambs assessed the effect of dietary inclusion of Prosopis laevigata pods (PLPs) on performance, carcass characteristics, meat traits and fatty acid profile of subcutaneous fat. Twenty-one Rambouillet lambs (27.0 ± 3.0 kg BW) were assigned to one of three experimental diets with 0, 150 and 300 g PLP/kg DM. Evaluation of growth performance lasted 49 days. The experimental design was completely randomized and analysed with a mixed model. Lambs fed diets with 0, 150 and 300 g PLP had similar growth performance. Lambs fed diets with 300 g PLP/kg DM had better (p < 0.05) carcass yield and classification, less (p < 0.05) fat deposition and lower lightness (L*) value (p < 0.05) in meat than lambs fed diets with 0 and 150 g PLP/kg DM. Saturated fatty acids (palmitic and stearic) decreased (p < 0.05) and unsaturated fatty acids (oleic and linoleic) increased (p < 0.05) in subcutaneous fat of lambs fed diets with 150 and 300 g pods as compared with lambs not fed PLP. Prosopis laevigata pods are a safe feedstuff that can replace a third of conventional ingredients and reduce feed costs in growing lambs. Addition of PLP reduced (p < 0.05) total feed cost by 21%.

Abstract
Field studies characterising the forage resources of mixed-breed goats on Chihuahuan Desert rangelands were reviewed and the principal sources of variation in their diet choices discussed. Goats eat a varied diet comprising at least 126 plant species in this landscape. Goats are highly selective feeders, changing their diet from predominantly forbs (8–64%) to browse (35–88%). Graminoids make up only ~5% of the diet, but grasses could be important dietary components on rangelands in good condition. Feed intakes range between 0.8% and 3.4% of bodyweight, depending on the season. DM digestibility of forage selected by goats ranges between 44% and 65%. Annual crude protein (CP) in forages selected by goats varies from 80 to 160 g CP kg–1 DM. Overall, pregnant and lactating goats manage to ingest food that contains higher amounts of CP and lower amounts of cell wall than non-pregnant, non-lactating goats. Goats not adapted to severe shortage of forage select a diet that does not match their nutritional requirements and fetal losses occur. Goat kids select higher quality diets than do mature goats (94.5 vs 88.5 g CP kg–1 DM). Granadina goats eat ~20% more shrubs, including 3-fold more Larrea tridentata (DC) Cav., than Nubian goats. Goats with severely eroded incisors avoid grasses, focusing on tender-leaved shrubs. During the rainy season, bucks select mainly shrubs (78% of the diet) and avoid grasses (1.7% of the diet), whereas does rely heavily on forbs (about one-third of their diet). Alternating use of grazing grounds increases shrub ingestion by 25%. No evidence exists indicating that food choice by goats in this arid environment is biased towards forages with lower secondary compounds. It is concluded that the flexible, broad-scale and opportunistic feeding behaviour of goats make them an effective animal to sustainably exploit the forage resources of the Chihuahuan Desert.

Abstract
The present study was conducted to evaluate the effect of replacement of Prosopis juliflora pods (PJP) in the concentrate mixture fed to sheep along with Cenchrus grass (CG). Twenty four adult Malpura rams (3-5 years, 45.4 ± 4.26 kg) were randomly divided into three equal groups on the basis of age and live weight (LW). Mature green Prosopis juliflora pods were collected, dried and ground to replace concentrate mixture at 0 (G1), 30% (G2) or 40% (G3). Cenchrus grass was offered ad libitum whereas the concentrate mixture was fed at the rate of 1% LW. Nutrient digestibility did not differ among the groups while N balance data showed reduced utilization in G3. However, the animals in G1, G2 and G3 maintained LW and their nutritional profile indicated surplus of energy and protein with comparable feed value of all the three diets. Rumen pH decreased and volatile fatty acids increased (P < 0.05) 4 h after feeding in G2 and G3 compared to G1. In summary, Prosopis juliflora pods can replace concentrate mixture up to 40% in sheep feeding without any adverse effect on nutrient intake and utilization as well as rumen fermentation characteristics.

Abstract
Prosopis juliflora, popularly known as Algaroba, is a major problem because the lack of food during the driest times of the year and its high palatability and nutritional value make its fruits (pods) much appreciated by cattle, goats, sheep and other animals. However, the consumption of this plant for long periods can cause a disease called cara-torta (pie face), which is characterized by cranial nerve dysfunction, mainly due to the degeneration and disappearance of neurons in the trigeminal motor nucleus. Algaroba contains piperidine alkaloids that have been suggested as being responsible for its toxicity; one of these alkaloids is juliprosopine. This study was conducted to evaluate the mechanisms of action of juliprosopine in isolated rat brain mitochondria to evaluate the potential mechanisms that lead to neurotoxicity in animals intoxicated by algaroba. Juliprosopine stimulated state-4 respiration at concentrations of 10-25 μM, affected the membrane potential at all concentrations studied (5-25 μM) and affected ATP production only at higher concentrations (15 and 25 μM). Juliprosopine cannot be classified as a member of the protonophoric class of uncouplers, such as 2,4-dinitrophenol or CCCP (m-chlorophenylhydrazone), due to its inability to promote mitochondrial swelling in the hyposmotic medium of potassium acetate. In addition, carboxyatractyloside, Mg(2+), cyclosporine A and dithiothreitol did not protect the uncoupling induced by juliprosopine. Because juliprosopine increased the fluorescence responses of mitochondria labeled with 1-aniline-8-naphthalene sulfonate (ANS) and DPH (1,6-diphenyl-1,3,5-hexatriene), we suggested that its uncoupling action must be attributed to a modification of the arrangement of the inner mitochondrial membrane.

Abstract
Descrevem-se três surtos de intoxicação por vagens de Prosopis juliflora no Sertão e Agreste de Pernambuco, na região semi-árida, em animais pastejando áreas invadidas pela planta ou que ingeriram as vagens como alimento concentrado. Em duas fazendas nas que a doença ocorria esporadicamente foram observados casos individuais. Em outra, o surto afetou um rebanho de 1206 bovinos, dos quais adoeceram 112 (9,28%) e morreram 84 (6,96%), enquanto os demais 28 (2,32%) recuperaram-se e ganharam peso após a retirada das vagens da alimentação. Clinicamente observou-se, principalmente, perda de peso progressiva, atrofia da musculatura da face e masseter, mandíbula pendulosa, protrusão de língua, dificuldade de apreensão e mastigação dos alimentos, torção da cabeça para mastigar ou ruminar, salivação excessiva, disfagia e hipotonia lingual. Nos exames laboratoriais constatou-se anemia e hipoproteinemia. Na necropsia havia caquexia e diminuição de volume e coloração acinzentada dos músculos masseteres. Na histologia observou-se degeneração de neurônios do núcleo motor do trigêmeo, degeneração Walleriana do nervo trigêmeo e atrofia muscular por denervação do músculo masseter com substituição por tecido fibroso. Recomendam-se medidas para a profilaxia da intoxicação e discute-se a necessidade de desenvolver pesquisas para determinar a viabilidade econômica e sustentabilidade da utilização da algaroba como alimento animal ou humano e para produção de carvão, lenha ou madeira.
