“…Faecal samples were collected and recorded from each pen at 8:00 and 20:00 on days 7, 21, 28, 35, and 42. The faecal score was determined as the average of five pigs in each pen using the following faecal scoring system: 1 -firm, formed stool; 2 -hard, dry pellets; 3 -soft, moist stool that retain its shape; 4 -unformed, soft stool that conform to the shape of the vessel; and 5 -watery, pourable liquids (Ahammad et al, 2023).…”

Pistachio shell powder is a high-fiber co-product from the pistachio nut industry that may provide energy and nutrients in animal diets, but no data have been reported for the nutritional value of pistachio shell powder when fed to pigs. Two experiments were, therefore, conducted to test the hypothesis that apparent total tract digestibility (ATTD) of gross energy (GE), dry matter (DM), and total dietary fiber (TDF) and concentration of digestible energy (DE) in pistachio shell powder are not different from those in soybean hulls when fed to gestating or lactating sows. In Exp. 1, twenty-four gestating sows were housed in metabolism crates and fed a corn-based basal diet or two diets that contained corn and 20% pistachio shell powder or corn and 20% soybean hulls. Sows were fed experimental diets for 13 days with feces and urine being quantitatively collected for 4 days after 6 days of adaptation. In Exp. 2, twenty-four lactating sows were housed in farrowing crates and fed a diet based on corn and soybean meal (SBM) or two diets that contained corn, SBM, and 20% of either pistachio shell powder or soybean hulls, and feces were collected for 6 days after 7 days of adaptation to the diets. Results indicated that for gestating sows, the diet containing soybean hulls had greater (P < 0.05) ATTD of DM, GE, and TDF than the diet containing pistachio shell powder. The DE and metabolizable energy (ME) in the pistachio shell powder diet were less (P < 0.05) than in the basal diet and the diet containing soybean hulls. The ME in pistachio shells (2,606 kcal/kg DM) was less (P < 0.05) than in soybean hulls (3,645 kcal/kg DM). When fed to lactating sows, ATTD of DM, GE, and TDF in the diet containing pistachio shell powder was less (P < 0.05) than in the diet containing soybean hulls or in the basal diet. The DE in the diet containing pistachio shell powder was also less (P < 0.05) than in the soybean hulls diet. The DE in pistachio shell powder (1,664 kcal/kg DM) was less (P < 0.05) than in soybean hulls (2,795 kcal/kg DM). In conclusion, the ATTD of DM and GE and the DE in pistachio shell powder were less than in soybean hulls, and inclusion in lactation diets, therefore, needs to be limited.

This study investigated the impacts of micellar quercetin (MQ) supplementation on growth performance, meat stability, excreta gas emissions, and physiological status. During a 35-day trial, 640 Ross 308 broilers were utilized. These birds were one day old, with an average initial body weight of 43.34 ± 1.43 g. They were randomly distributed across four experimental diets, each consisting of 10 replicate pens with 16 chicks per pen. The diets included the following: control (CON) with 0% micellar quercetin (MQ), TRT1 with 0.025% MQ, TRT2 with 0.050% MQ, and TRT3 with 0.100% MQ. The results indicate that broilers fed diets with increasing levels of MQ exhibited significantly higher body weight gains (BWGs) compared to the control group (p < 0.05). There was a clear linear increase in the breast muscle percentage with higher levels of quercetin supplementation (p < 0.05), while the breast color remained consistent across all groups (p > 0.05). Both cooking loss and drip loss exhibited a linear decrease as MQ levels in the diet increased (p < 0.05). The level of aspartate aminotransferase (AST) tended to decrease with higher MQ levels. Thyroxine (T4) and lymphocyte levels also showed a linear increase with increasing MQ dosage in the diet (p < 0.05). However, no significant effects were observed on nutrient digestibility, gas emissions, or fecal microbial components (Lactobacillus, E. coli, and Salmonella) with higher levels of MQ supplementation (p > 0.05). In conclusion, augmenting quercetin levels in the diet positively influenced the BWG, breast muscle development, and meat quality parameters such as cooking loss and drip loss, with beneficial effects on blood profiles.
