Abstract

Consumer demand for high-quality meat has increased. This study aimed to investigate the potential application of cocrystals of thymol and carvacrol in broilers for high-quality meat production. Eight hundred 1-day-old chicks were assigned to four groups fed diets supplemented with 0, 40, 60, and 80 mg/kg of Crystal EO® (CEO), containing 25% cocrystals of thymol and carvacrol in a 42-d feeding trial. The results showed that dietary CEO supplementation decreased the muscle fiber diameter and increased the muscle fiber density, glycogen content, L*45 min value, and proportion of α-linolenic acid in the breast muscle; dietary 40 and 60 mg/kg of CEO decreased the lactate content, MDA concentration, cooking loss, shear force, and thrombogenicity index and increased the proportion of lauric acid in the breast muscle; dietary 60 and 80 mg/kg of CEO increased the glucose content, total superoxide dismutase, and total antioxidant capacity levels of breast muscle. Citrate synthase activity, free radical scavenging capacity, pH24 h and a*45 min values, and the cystine content in the breast muscle were especially higher in the 60 mg/kg CEO group compared to the control group. Collectively, dietary CEO supplementation improved meat quality and nutritional values and enhanced the antioxidant capacity of broiler meat, with 60 mg/kg of CEO having the greatest effect.

Abstract

Zearalenone (ZEN) is a nonsteroidal estrogenic mycotoxin produced by Fusarium strains that is harmful to the intestinal health of animals and is widely present in contaminated crops. The objective of this study was to investigate the potential therapeutic target of ZEN-induced jejunal damage in weaned gilts. Sixteen weaned gilts either received a basal diet or a basal diet supplemented with 3.0 mg/kg ZEN in a 32-d experiment. The results showed that ZEN at the concentration of 3.0 mg/kg diet activated the inflammatory response and caused oxidative stress of gilts (P  < 0.05). ZEN exposure resulted in the upregulation (P  < 0.05) of the Exchange protein directly activated by the cAMP 1/Ras-related protein1/c-Jun N-terminal kinase (Epac1/Rap1/JNK) signaling pathway in the jejunum of gilts in vivo and in the intestinal porcine epithelial cells in vitro. The cell viability, EdU-positive cells, and the mRNA expression of B-cell lymphoma-2 (Bcl-2) were decreased, whereas the reactive oxygen species production and the mRNA expressions of Bcl-2-associated X (Bax) and Cysteine-aspartic acid protease 3 (Caspase3) were increased (P  < 0.05) by ZEN. However, ZEN increased the mRNA expression of Bcl-2 and decreased the mRNA expressions of Bax and caspase3 (P  < 0.05) after the Epac1 was blocked. These results collectively indicated that a 3.0 mg ZEN /kg diet induced jejunal damage via the Epac1/Rap1/JNK signaling pathway. [ABSTRACT FROM AUTHOR]

Abstract

Alpha-linolenic acid (ALA), which is an n-3 polyunsaturated fatty acid (PUFA), influences honey bee feed intake and longevity. The objective of this study was to research the effect of six dietary ALA levels on the growth and development of Apis mellifera ligustica colonies. In the early spring, a total of 36 honey bee colonies of equal size and queen quality were randomly allocated into 6 groups. The six groups of honey bees were fed a basal diet with supplementation of ALA levels at 0 (group A), 2 (group B), 4 (group C), 6 (group D), 8 (group E), and 10% (group F). In this study, there were significant effects of pollen substitute ALA levels on the feeding amounts of the bee colony, colony population, sealed brood amount, and weight of newly emerged workers (P

Abstract

This study investigated the effects of inorganic trace elements (IEs) and sucrose chelated trace elements (SEs) on the growth performance, nutrients and energy utilization, antioxidant capacity, and mineral deposition in broiler chickens, and the efficiency of IEs replaced by SEs at different levels was also evaluated. A total of 448,21-day-old male Arbor Acres broiler chickens with similar body weights were randomly assigned into 6 dietary treatments (8 cages/treatments) in a complete randomized design. Treatments were a basal diet including 2.0 g/kg of IE (IE-2.0) premix, and SE-2.0, SE-1.5, SE-1.0, SE-0.5, and SE-0 were basal diets in which IEs were replaced by SE premix at 2.0, 1.5, 1.0, 0.5, and 0 g/kg, respectively. In general, there was a linear and quadratic decrease in growth performance including average daily feed intake (ADFI) and average daily gain (ADG), apparent and true availability of nutrients (DM, OM, and CP), GE, trace elements (Cu, Zn, Mn, Fe, I, and Se), essential AA (Lys, Met, Arg, His, Phe, Thr, and Val), non-essential AA (Asp, Ser, Glu, Gly, and Cys), superoxide dismutase (SOD), and trace elements (Fe, Zn, Cu, and Mn) in the liver, and an increase in feed-to-gain ratio (F/G) and liver malondialdehyde (MDA), with decreasing SE levels (p < 0.05). In conclusion, under the conditions of this experiment, using half of the sucrose chelated trace elements (Cu, Fe, Zn, and Mn) instead of inorganic trace elements did not affect the growth performance, nutrients and energy utilization, antioxidant capacity, and liver trace element deposition in broiler chickens.
