Nutraceuticals comprise amino acids, antioxidants, minerals, vitamins, probiotics, prebiotics, synbiotics, enzymes, organic acids, fatty acids, medicinal plants, etc. Recently, nutraceuticals have acquired much attention in poultry industry by reason of their potential effects on establishing the normal physiological status, supporting the immune system, and disease prevention, which consequently enhances productivity. The technique of in ovo feeding (IOF) of nutraceuticals holds several promises in poultry industry. The vital benefits of IOF of nutraceuticals are enhancement of intestinal development, establishment of a balanced microbial population in the gut, support of intestinal physiology and health. Interestingly, IOF of nutraceuticals participates in improving the antioxidative properties and energizing the immune system, which thereby translated into greater performance and bigger resistance to diseases, especially in early life challenges. The current review attempts to throw more light on the fresh results associated with the profits of IOF of nutraceuticals on intestinal histomorphology, intestinal microbiota, antioxidative properties, immune responsiveness, hatchability, chick quality, and growth performance in poultry.

A total of 320-day-old Ross 308 broilers were assigned to eight treatments of four replicates with 10 birds. Oral inoculation of the challenged groups with Eimeria tenella occurred on day 8. On day 10, disease challenge and additive level significantly (P = 0.003) interacted, decreasing the feed intake. Feed intake significantly (P ≤ 0.001) decreased in birds supplemented with 10 g/kg of chamomile. At 35 days, birds fed chamomile and anticoccidial significantly (P = 0.001) increased body weight (BW) and weight gain (WG). Disease challenge adversely influenced (P = 0.001) BW and WG. Additive level and disease challenge significantly (P = 0.001) interacted on feed conversion ratio (FCR). Anticoccidial and chamomile improved (P = 0.001) FCR of birds regardless of the rearing conditions. Significantly (P = 0.001) better FCR was observed in the unchallenged birds. The interaction of experimental factors was significant (P ≤ 0.04) on the relative weight of bursa. Disease challenge significantly (P = 0.005) increased the relative weight of liver whereas that of bursa decreased. Cholesterol (P = 0.002), albumin/globulin (P = 0.009), aspartate aminotransferase (AST) (P = 0.002) and alanine transaminase (ALT) (P = 0.001) significantly increased in challenged birds. The interaction of experimental factors was significant (P = 0.002) on villus length, crypt depth and villus height/crypt depth ratio (P = 0.001). Longer (P = 0.001) villi were found in anticoccidial and chamomile supplemented birds. Coccidiosis adversely (P = 0.001) influenced the jejunum morphology. Crypt depth decreased and villus height/crypt depth increased in chamomile offered birds (P = 0.001) regardless of the challenge conditions. Bursal morphology was significantly influenced by experimental factors. Dietary supplementation of chamomile had positive effects on broiler performance, immunity and intestinal morphology during exposure to the E. tenella parasite. Chamomile could be used as a potential natural anticoccidial in broiler nutrition.

However, little is known about research reports on housefly larvae extracts containing an antibacterial peptide. This study investigated the effect of feeding diets supplemented with housefly larvae extract (HLE) containing antibacterial peptides on the growth performance of broiler chickens. Nine hundred broilers (Ross 308) were fed diets containing HLE for 35 days. Treatment groups consisted of CON (control without HLE), PC (positive control, 8 ppm of avilamycin), HLE50 (diet containing 50 ppm of HLE), HLE100 (diet containing 100 ppm of HLE), HLE150 (diet containing 150 ppm of HLE), and HLE200 (diet containing 200 ppm of HLE). Body weight gain and feed conversion ratio were significantly (P < 0.05) increased in HLE150 and HLE200 groups compared to those in the CON group. Spleen weights were higher in HLE150 and HLE200 groups than in the CON group. Caecal bifidobacteria and Lactobacillus counts were significantly (P < 0.05) higher in HLE150 and HLE200 groups whereas E. coli and coliform bacteria counts were higher in the CON group. Caecal acetic acid, propionic acid, and total short-chain fatty acid levels were significantly (P < 0.05) higher in HLE150 and HLE200 groups than in the CON group. These results show that feeding diets containing 150 ppm of HLE containing antimicrobial peptides could replace antibiotics to improve the growth performance of broiler chickens.

China Title: Label-free proteomics to identify keratins and keratin-associated proteins and their effects on the fleece traits of Inner Mongolia Cashmere Goats Abstract: Inner Mongolia Cashmere Goat fleece is derived from a heterogeneous coat. The guard hair is produced by primary hair follicles, and the down hair is produced by secondary hair follicles. Reports have focused on research related to the different hair follicle types, but no related study has addressed the difference in the proteins of down hair (DH) and guard hair (GH), and whether the protein composition of these materials differs remains to be studied. The protein composition of DH and GH was studied. A total of 108 proteins were identified in DH, and 116 proteins were identified in GH; 39 proteins were differentially expressed, of which 18 proteins were upregulated and 21 proteins were downregulated in DH versus GH. In this study, through the measurement of DH and GH samples from Inner Mongolia Cashmere Goats, the diameter of DH relative to GH was downregulated (P < 0.05), a property that may be related to the KRT38 protein. Moreover, the strength of GH was significantly higher than that of DH (P < 0.05), a property that may be affected by the KRTAP8-1 protein. GO analysis showed that the different traits of DH and GH from Inner Mongolia Cashmere Goats are affected by keratin, actin, and calcium-binding proteins. This study uses a nonlabelled quantitative proteomics method to study the proteins in DH and GH, aiming to identify the keratin family in Inner Mongolia Cashmere Goats and to provide a new direction for studying DH and GH traits at the protein level.
