Abstract
The present study aimed to investigate the effect of emulsifier lysophospholipids (LP), enzymatically modified from soy phospholipids, on the growth performance, nutrient digestibility, lipid metabolism and meat quality of fattening rabbits. The LP was added in control (CON), LP1, LP2 and LP3 at 0, 200, 400 and 600 mg/kg, respectively. A total of 240 rabbits at approximately 52 d of age were divided into 4 groups with 6 replicates of 10 rabbits each. The feeding trial lasted for 42 d. Results showed that compared to CON, LP1, LP2 and LP3 increased (p < 0.05) body weight gain, feed efficiency, the apparent faecal digestibility of gross energy, crude protein and ether extract, the percentages of dissectible fat and ether extract in the longissimus and legs, the serum contents of apolipoprotein B, free fatty acid and total phospholipids in the longissimus, but decreased (p < 0.05) serum total triglyceride and total cholesterol. Meanwhile, LP1, LP2 and LP3 had higher (p < 0.05) carcass weight, longissimus weight and percentages of foreleg and hindleg than the CON; and the three LP diets also increased (p < 0.05) the tenderness, lightness and redness of longissimus. It is concluded that soy LP as an emulsifier can improve the growth, digestibility and meat quality of fattening rabbits.

Abstract
This study aimed to investigate the effect of dietary tetramethylpyrazine (TMP) on the growth performance, nutrient digestion, blood parameters and immunity of broilers under oxidative stress. Five treatments included negative control, positive control with lipopolysaccharide induction and TMP addition at 50, 100 and 150 mg/kg of diet using 600 male Arbor Acres broiler chicks. Results showed that during 1-14 days of age, body weight gain and feed efficiency in the positive control were worsened (p < .05) compared with the negative control, while with incremental TMP doses from 0 to 150 mg/kg there were linear and quadratic increases (p < .001) in body weight gain and a linear decrease in feed/gain (p = .001). During 12-14 days of age, with incremental TMP doses, crude protein digestibility was linearly increased (p = .001), and gross energy utilization was linearly and quadratically changed (p < .001). At 14 days of age, the TMP beneficially regulated digestive enzymes, blood parameters and immunoglobulins, showing linear and quadratic responses (p ≤ .008) on trypsin, lipase, glutamic pyruvic transaminase, glucose, lipoproteins, albumin, immunoglobulins (M, Y), interleukin 6 and interferon α, and only linear changes (p ≤ .030) on amylase, glutamic oxaloacetic transaminase, immunoglobulin A and interleukin 2. Most parameters in TMP groups reached to the levels of negative control and the effects of TMP at 100 or 150 mg/kg were more pronounced on body weight gain, crude protein digestibility, trypsin and glutamic pyruvic transaminase. It is concluded that TMP can be used as a feed additive capable of improving growth, blood parameter and immunity of broiler chicks under oxidative stress.

Effect of a Phytogenic Feed Additive on Growth Performance, Nutrient Digestion, and Immune Response in Broiler-Fed Diets with Two Different Levels of Crude Protein. Animals (Basel) 2021; 11:ani11030775. [PMID: 33799557 PMCID: PMC7999929 DOI: 10.3390/ani11030775] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Revised: 03/05/2021] [Accepted: 03/08/2021] [Indexed: 12/22/2022] Open
Abstract
Simple Summary The rising concerns on antibiotics resistance from using antibiotics in animal production has resulted in an increase in researches on antibiotic alternatives. A phytogenic feed additive from a blend of extracts of oregano, cinnamon, citrus peel, and fructooligosaccharides was evaluated in the present study. The objective of the present study is not only to evaluate the effect of phytogenic feed additive on broiler performance, but also to explore the potential mode of actions through immune response, digestive enzyme activities, nutrient transporter gene expressions and nutrient digestibility. Supplementation of phytogenic feed additives improved broiler FCR through stimulating ileum immunity. Abstract The aim of this experiment was to evaluate the effect of a phytogenic feed additive (PFA) on growth performance and nutrient digestibility of broilers fed corn and soybean meal-based diets containing two different levels of crude protein. A 2 × 2 completely randomized factorial arrangement (eight replicates/treatment, 30 birds/replicate) was conducted with a positive control (PC) and negative control (NC) containing crude protein at standard or reduced by 1.5% (equivalent to a reduction of 15 g/kg), respectively, and supplementation of PFA at 0 or 125 ppm of diet. There were no significant interactions found between PFA and CP levels in the current study. Main effect analysis showed that during 0–42 d of age NC diets decreased body weight gain (p < 0.05), but increased feed intake (p < 0.05) and feed conversion ratio (FCR, p < 0.01), whereas supplementation of PFA resulted in a lower FCR (p < 0.01). The ileal nutrient digestibility was reduced (p < 0.05) in the broilers fed a reduced protein diet at 21 d compared to the standard protein level group, but there were no effects for PFA levels. Similarly, supplementing PFAs showed no effects on digestive enzyme (Alkaline phosphatase, amylase, and lipase) activity in jejunal digesta and jejunal brush border enzyme (maltase, sucrase, and aminopeptidase) activity. Supplementation of PFA downregulated (p < 0.05) the mRNA expressions of cytochrome P450 1A and interleukin 6 in the ileum but had no effects on nutrient transporter genes in the jejunum. In conclusion, supplementation of PFA reduced broiler FCR during the whole grow-out period and positively regulated the immune responses in the ileum.

Food Chem 2021; 351:129278. [PMID: 33631612 DOI: 10.1016/j.foodchem.2021.129278] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Revised: 01/28/2021] [Accepted: 01/29/2021] [Indexed: 11/17/2022]
Abstract
The poor gel strength and microbial infection of conventional chicken myofibrillar protein (CMP) gels have severely limited the application. Here, plasma activated water (PAW) instead of normal water was used to prepare CMP gels. PAW prepared by treating deionized water with plasma jet was incubated with CMPs and followed by heating to prepare CMP gels. Effects of PAW on CMP gels were assessed in terms of basic physicochemical properties, network structure, and antibacterial activity. The results showed that PAW treatment accelerated the aggregation of CMPs and increased the strength and water holding capacity of CMP gels. Due to the presence of NO and NO2 free radicals in PAW, the prepared CMP gels were endowed with antibacterial activity against Salmonella Enteritidis and Staphylococcus aureus. The new method of PAW-induced CMP gels will have the prospect of improving the quality of gels and extending the shelf life of chicken gel products.
