Based on a circular economy approach, we evaluated the possible effect of targeted supplementation with leftover feed from dairy cows (i.e., intensive system) reproductive performance crossbred/rangeland goats extensive in arid Northern Mexico. During deep-anestrous season March-April, 25° North), multiparous (n = 38) similar body weight (BW) and condition score (BCS) were randomly assigned to two groups: (1) supplemented group (SG; n 19; BCS: 1.76 ± 0.07; BW: 43.7 1.8 kg), receiving 400 g goat d-1 dairy-cow-feed leftovers prior grazing; (2) non-supplemented (NS; 0.06; 44.3 2.5 kg). Both groups directed rangeland for period ≈8 h. While experimental lasted 36 d, breeding considered 11 d (d0-d10). The anovulatory status was ultrasonographically confirmed days -20, -10, -1 male-female interaction. Previously, bucks separated 3 weeks females received exogenous testosterone every third day 50 mg i.m.) mating. With respect response variables, namely BW, BCS, blood glucose levels (BGLs), estrus induction (GIE, %), latency (LTE, h), duration (ED, luteal tissue volume (LTV, mm), no differences (p > 0.05) occurred between groups. However, ovulating (GO, %; 78.9 vs. 47.3), total number corpuses luteum (TNCL, n; 27 13), ovulation rate (OR, 1.42 0.73), multiple (MO, 73.3 55.5), pregnancy (PRd36, %, 68.4 36.8), favored < SG over NS goats. Our results demonstrate that connecting circularity divergent ruminant production systems cow-intensive goat-extensive) by using cows' as strategy anestrous under marginal-rangeland system enhanced out-of-season outcomes rate), thus benefiting marginal producers their families.

Aflatoxins (AFs) represent one of the main mycotoxins produced by Aspergillus flavus and parasiticus, with most prevalent lethal subtypes being AFB1, AFB2, AFG1, AFG2. AFs are responsible for causing significant public health issues economic concerns that affect consumers farmers globally. Chronic exposure to has been linked liver cancer, oxidative stress, fetal growth abnormalities among other health-related risks. Although there various technologies, such as physical, chemical, biological controls have employed alleviate toxic effects AF, is still no clearly elucidated universal method available reduce AF levels in food feed; only mitigation early detection toxin management contamination. Numerous methods, including cultures, molecular techniques, immunochemical, electrochemical immunosensor, chromatographic, spectroscopic means, used determine contamination agricultural products. Recent research shown incorporating crops higher resistance, sorghum, into animal feed can risk milk cheese. This review provides a current overview risks chronic dietary exposure, recent strategies guide future researchers developing better this toxin.

Aflatoxin B1 (AFB1) exhibits the most potent mutagenic and carcinogenic activity among aflatoxins. For this reason, AFB1 is recognized as a human group 1 carcinogen by International Agency of Research on Cancer. Consequently, it essential to determine its properties behavior in different chemical systems. The can be explored using computational chemistry, which has been employed complementarily experimental investigations. present review includes silico studies (semiempirical, Hartree–Fock, DFT, molecular docking, dynamics) conducted from first study 1974 (2022). This work was performed, considering following groups: (a) (structural, energy, solvent effects, ground excited state, atomic charges, others); (b) theoretical investigations (degradation, quantification, reactivity, (c) interactions with inorganic compounds (Ag+, Zn2+, Mg2+); (d) environmentally (clays); (e) biological (DNA, enzymes, cyclodextrins, glucans, others). Accordingly, work, we provide stakeholder knowledge toxicity types AFB1-derivatives, structure–activity relationships manifested bonds between DNA or proteins, strategies that have quantify, detect, eliminate molecule.

The conversion of aflatoxin B1 in feed consumed by cows into M1 their milk poses a challenge to food safety, with being popular staple and because the harmful effects these compounds. This study aimed at reviewing scientific information about extent carry-over AFB1 from milk. A range studies reported correlations different factors, particularly yield intake. considerably varies, 1–2% on average, which may be as high 6% case increased production. Specific factors influencing transfer rates, including yield, somatic cell counts, intake, source contamination, seasonal effects, particle size feed, certain interventions, namely vaccination use adsorbents, are identified most important discussed this review. mathematical formulas describing instances application reviewed well. These equations lead largely results, no single equation can suggested best one. While exact quantification is difficult process depends many individual variabilities between animals, intake seem excreted amount rate carry-over.

Twenty female Italian calves (37.14 ± 2.72 kg) born between February July were studied from day birth until 77 days age. From fourth life, they fed 3 L/day pasteurized milk twice daily supplemented with same TMR. data characteristics, performances collected showed that these had adequate parameters. Moreover, used create equations predict using model. goodness fit developed evaluated by coefficients determinations (R2). obtained shows high R2 (0.98 0.99 calf weight), indicating satisfactory precision accuracy needed calves' intake.

Mycotoxin contamination on food and feed can have deleterious effect human animal health. Agricultural crops may contain one or more mycotoxin compounds; therefore, a good multiplex detection method is desirable to ensure safety. In this study, we developed rapid using label-free surface-enhanced Raman spectroscopy (SERS) simultaneously detect three common types of mycotoxins found corn, namely aflatoxin B1 (AFB1), zearalenone (ZEN), ochratoxin A (OTA). The intrinsic chemical fingerprint from each was characterized by their unique spectra, enabling clear discrimination between them. limit (LOD) AFB1, ZEN, OTA corn were 10 ppb (32 nM), 20 (64 100 (248 respectively. Multivariate statistical analysis used predict concentrations up 1.5 ppm (4.8 µM) based the SERS spectra known concentrations, resulting in correlation coefficient 0.74, 0.89, 0.72, sampling time less than 30 min per sample. application multivariate promising for simultaneous be extended other crops.

The aim of this study was to estimate the aflatoxin M1 (AFM1) contamination in raw milk and processed (pasteurized or UHT) collected from two regions Italy (Puglia Basilicata) during a 12-year period: 2012–2023. A total 1017 samples were analyzed first proceeding with screening analysis by enzyme-linked immunosorbent assay (ELISA), suspected non-compliant (AFM1 concentration higher than 0.042 µg/kg) then high performance liquid chromatographic fluorimetric detection (HPLC/FLD) confirmation method. AFM1 ≥ 0.005 µg/kg (ELISA limit quantitation) detected 553 (54.4%). levels exceeding European Union maximum (ML) 0.050 70 samples, 49 which determined as (4.8%). Particularly concentrations AFM1, 200 µg/kg, found four three one pasteurized. Regarding risk exposure study, only MOE values obtained under “high scenario” 10,000, while those calculated overall mean resulted not concern.

Abstract This study investigates the impact of urea molasses-treated wheat straw on growth performance and nutrient digestibility in Azikheli buffalo male calves. A longitudinal experiment was conducted sixteen calves, randomly assigned to four experimental dietary treatments ( n = 4 per group). The diets included a control group (U0) with untreated three groups where replaced 33% (U33), 66% (U66), or 100% (U100) total mixed ration. Results indicated that increasing proportion urea-treated from 0 led significant improvements dry matter intake (from 2931 4034 g/day) organic 2596 3623 g/day). Digestibility matter, crude protein, fiber also followed an trend, reaching 77.42%, 81.21%, 87.10%, 60.22%, respectively, at highest level. Furthermore, weight gain significantly greater calves fed straw, by those U66, U33, U0 groups. Feed conversion efficiency improved substantially U100 U66 than U33 U0. These findings suggest incorporating higher levels UMTWS rations enhances digestibility, promoting superior feed
