    Abstract The aim of this study was to conduct a comprehensive review with meta-analysis to determine the effects of the dose-response relationship between monensin supplementation and dairy cow performance and milk composition. Results from 566 full-text articles and 48 articles with 52 studies were meta-analyzed for pooled estimates. Monensin supplementation up to 23 ppm increased milk production, with the optimal dose being 12.6 ppm. Monensin supplementation at doses ranging from 16 to 96 ppm increased milk production in the prepartum phase (- 28 to 0 day relative to calving). From 60 to 150 DIM, monensin supplementation up to 21 ppm had a significant positive effect on this outcome, while supplementation in the 37 to 96 ppm range caused a decrease in this variable. At 0 to 60 and > 150 DIM, monensin supplementation had no effect on milk yield. At dosages of 22 to 96 ppm, 12 to 36 ppm, and below 58 ppm and 35 ppm, respectively, monensin supplementation resulted in significant decreases in dry matter intake (DMI), milk protein percentage, milk fat percentage, and milk fat yield. Overall, based on the results of this meta-analysis and considering all variables, the recommended optimal dose of monensin could be about 16 ppm.

    Abstract To investigate the effects of supplemental monensin administration on the metabolic responses of dairy cows, a systematic review and dose-response meta-analysis were conducted. Initially, 604 studies were identified through comprehensive database searches, including Google Scholar, Scopus, Science Direct, and PubMed, using key words related to dairy cows, monensin, and metabolic outcomes. After a 2-stage screening process, 51 articles with a total of 60 experiments were selected for meta-analysis based on criteria such as study implementation date between 2001 and 2022, presence of a control group that did not receive monensin supplementation, reporting of at least 1 outcome variable, and presentation of means and corresponding errors. The meta-analysis used the 1-stage random-effects method, and sensitivity analyses were performed to assess the robustness of the results. The results showed that the administration of monensin at a dosage of 19 to 26 mg/kg was inversely related to methane emissions and that the administration of monensin at a dosage of 18 to 50 mg/kg resulted in a significant decrease in dry matter intake. Administration of monensin at doses of 13 to 28 and 15 to 24 mg/kg also resulted in a significant decrease in ruminal acetate proportion and an increase in propionate proportion, respectively, with no effects on ruminal butyrate, NH

    Abstract The aim of this study was to evaluate the effects of dietary urea-treated pomegranate (Punica granatum L.) peel (UTPP) on growth performance, carcass attributes, blood biochemical indices, immunity, intestinal morphology, and meat quality of broiler chickens subjected to heat stress. The treatment with urea increased the gross energy and crude protein contents, while decreased the ash, calcium, phosphorous, neutral detergent fiber, acid detergent fiber, extractable polyphenols, total anthocyanins, condensed tannins, and hydrolyzable polyphenols contents of pomegranate peel. A total of 200 1-day-old male broiler chickens were randomly allocated to four groups; each group had 5 floor pens with 10 birds each. The broiler chickens were fed with the basal diet containing 0, 15, 30 or 50 g UTPP / kg diet from day 1, and exposed to a cyclic high temperature (37 ± 1 °C, 55 % relative humidity) for 6 h / day from day 29–42. Dietary UTPP increased body weight gain during the starter (linear (L), P = 0.001; quadratic (Q), P < 0.001) and overall experimental (L, P = 0.019; Q, P = 0.004) periods. However, it reduced feed intake during the starter (Q, P = 0.004) and grower (L, P = 0.019; Q, P = 0.007) periods. Dietary UTPP improved the feed conversion ratio during the starter (L, P < 0.001; Q, P < 0.001), grower (L, P = 0.018), finisher (L, P = 0.004), and overall experimental (L, P = 0.001) periods. The breast yield quadratically increased as UTPP level increased (P = 0.002), while the liver (L, P = 0.002) and abdominal fat (L, P < 0.001) percentages decreased. The concentration of blood glucose (P < 0.001), high density lipoprotein (P = 0.01), and globulin (P = 0.001) linearly increased with UTPP inclusion, but the plasma albumin (L, P < 0.001), alkaline phosphatase (L, P < 0.001), alanine aminotransferase (L, P < 0.001; Q, P < 0.001), lactate dehydrogenase (L, P < 0.001), cholesterol (L, P < 0.001; Q, P < 0.001), low-density lipoprotein (L, P < 0.001; Q, P < 0.001), and malondialdehyde (L, P < 0.001) concentrations decreased at day 42. The bursa percentage increased (L, P = 0.011; Q, P = 0.006) as UTPP level increased. Dietary UTPP also improved the primary total (L, P < 0.001), IgM (L, P < 0.001; Q, P = 0.003), and IgG (Q, P = 0.015) responses and the secondary total (L, P < 0.001; Q, P = 0.024) and IgG (L, P < 0.001) responses against sheep red blood cells. It increased the villus height (L, P < 0.001; Q, P = 0.003), crypt depth (L, P < 0.001; Q, P < 0.001), and villus height / crypt depth ratio (L, P < 0.001; Q, P = 0.001), while decreased the villus width (L, P < 0.001; Q, P = 0.038). Dietary UTPP improved the oxidative stability and water holding capacity of breast meat prior to and during frozen storage. Overall, based on the estimates from the regression models, UTPP (at a level of 26.1–50 g / kg) can be included as a cheap and valuable feed ingredient in heat-stressed broiler chickens diets.
