“…These results, along with the result of intestinal weight, suggested that IOF of Arg solution mainly promoted the growth performance of early‐stage chicks from 1 to 21 days. Previous studies also reported that the effects of IOF nutrients might be limited, and that positive effects could be attenuated after the birds gained access to feed posthatch . Besides, Tahmasebi and Toghyani reported that IOF of Arg solution significantly increased chick BW at 24 days posthatch and FI during 1–42 days compared with the control group .…”

In ovo feeding of l‐arginine regulates intestinal barrier functions of posthatch broilers by activating the mTOR signaling pathway

The IOF of Arg improved the development and barrier functions of small intestine, which might be associated with activating the mTOR pathway. In addition, the improved intestinal development might explain the improvement in feed intake and consequently the growth performance of broilers. Therefore, IOF of Arg solution could be an effective technology for regulating early nutrition supply and subsequent growth development in the poultry industry. © 2017 Society of Chemical Industry.

“…A previously described method to prepare samples for histomorphometry analysis was used ( Kermanshahi et al., 2017a ). Briefly, the jejunal content was flushed out with physiological saline and a section of 2 cm of the tissue (midway between the Meckel's diverticulum and the entrance of the bile ducts) was stored in 10% formalin for 48 h followed by paraffin embedding cut to a thickness of 5 μm using a microtome.…”

Clostridium perfringens -induced necrotic enteritis ( NE ) is an economically important disease of broiler chickens. The present study evaluated the effect of C. perfringens on the intestinal histomorphometry, enteric microbial colonization, and host immune responses using 3 experimental NE reproduction methods. The experimental groups consisted of 1) unchallenged Control diet (corn-soybean meal), 2) Control diet + Eimera inoculation at d 11 followed by C. perfringens challenge at d 15 ( ECp ), 3) Wheat-based diet + C. perfringens challenge ( WCp ), and 4) Wheat-based diet + Eimeria inoculation followed by C. perfringens challenge ( WECp ). The results showed that chickens receiving ECp and WECp had reduced ( P < 0.05) bird performance coupled with enteric gross lesions and epithelial damage at d 17 and 24 of age compared to unchallenged control birds. These ECp and WECp administered birds also had increased ( P < 0.05) ileal colonization by clostridia and E. coli at d 17 and 24, while the resident Lactobacillus counts were reduced ( P < 0.05) at d 24 of age. Furthermore, at d 24, jejunal transcription of IL-6, IL-10, annexin-A1 and IL-2 genes was upregulated ( P < 0.05) in the ECp group, whereas the transcription of TNF receptor associated factor (TRAF)-3 gene was increased ( P < 0.05) in WECp treated birds when compared to unchallenged control group. Additionally, stimulation of chicken splenocytes and cecal tonsilocytes with virulent C. perfringens bacilli or their secretory proteins resulted in a higher ( P < 0.05) frequency of T cells and their upregulation of MHC-II molecule, as determined by flow cytometry. These findings suggest that C. perfringens , while inducing epithelial damage and changes in microbiota, can also trigger host immune responses. Furthermore, NE reproduction methods using coccidia with or without the wheat-based dietary predisposition seem to facilitate an optimal NE reproduction in broiler chickens and thus, may provide better avenues for future C. perfringens research.

“…Embryonic development is affected by many factors, including egg nutrition, temperature, and humidity (Dymond et al, 2013;Noiva et al, 2014;Yildirim and Yetisir, 2004). Previous reports have indicated that the changes in egg nutrition affect the embryonic development and health (Bhattacharyya et al, 2018;Kermanshahi et al, 2017). Other researchers have shown that restricting maternal nutrition affects the development of embryos (Prezotto et al, 2016;Raja et al, 2016).…”

The objective of this study was to evaluate the effects of maternal dietary intake on the amino acid and fatty acid contents in eggs during the laying period. An experiment with a 2×2 factorial design was conducted with two maternal dietary intake levels (100 and 75% of dietary intake recommended by the Chinese Ministry of Agriculture) and two broiler lines (fat and lean line). A total of 384 hens of fat line and 384 hens of lean line at 23 weeks of age were included in the experiment. Each line was randomly divided into two treatments (n = 192 in each treatment, with 12 replications), and each replication included 16 birds. The treatments were LN (lean line and normal maternal dietary intake, n = 192), LL (lean line and low maternal dietary intake, n = 192), FN (fat line and normal maternal dietary intake, n = 192), and FL (fat line and low maternal dietary intake, n = 192). The amino acid and fatty acid contents in eggs were tested (50 weeks of age). The fat line had higher levels of arginine, aspartic acid, glycine, histidine, leucine, methionine, and threonine in the egg albumen than the lean line. Low maternal dietary intake increased the cystine deposition in egg yolks. There were interactions between maternal dietary intake and line on the deposition of trans-oleic acid, docosanoic acid, and total fatty acid in egg yolks. Low maternal dietary intake increased the deposition of tetradecenoic and linolenic acids and the ratio of total polyunsaturated fatty acids to total saturated fatty acid in egg yolks but decreased the deposition of docosanoic acid. Maternal dietary intake and line affect the amino acid and fatty acid profiles in eggs.
