“…2 NC, negative control; PC, positive control, birds were given an in-feed anticoccidial drug; VAC, vaccinated, birds were given a commercial dose of vaccine on 0 d. in lipid digestibility. The profound effect of coccidia on lipid digestibility can subsequently impair the absorption of other fatsoluble nutrients, including vitamin D, which can consequently impair the absorption of calcium and phosphorus, negatively impacting bone development (28)(29)(30). Increased digesta lipid content may also reduce the absorption of calcium via intestinal soap formation, and excess calcium in the intestinal lumen may be another predisposing factor for necrotic enteritis (31).…”

“…In the current experiment, jejunum villi height was not influenced by coccidiosis vaccination at 12 d post-hatch when the greatest impacts of vaccination on nutrient and energy digestibility were observed. Although severe coccidiosis can cause morphologic damage to the intestinal mucosa, as indicated by increased crypt cell depth and shortened villi (30,34), other authors have similarly reported a lack of effects of coccidiosis vaccines on intestinal morphology when administered at commercially recommended doses (35,36). There was a tendency for VAC birds to have deeper crypts in the jejunum at 12 d post-hatch in the current experiment, and this may be reflective of increased cellular proliferation to maintain villi structure during periods of increased enterocyte turnover associated with vaccine-induced coccidiasis.…”

An experiment was conducted to quantify the timing and magnitude of the effects of coccidiosis vaccination on the growth performance, apparent ileal digestibility (AID) of nutrients and energy, intestinal morphology, and plasma carotenoids and nitric oxide in broilers. Treatment groups consisted of 3 coccidiosis control methods [unvaccinated, unmedicated (NC), in-feed chemical coccidiostat (PC), and live oocyst vaccination (VAC) at day of hatch] administered to male Cobb broilers reared in floor pens. Body weight gain (BWG), feed intake (FI), and feed conversion ratio (FCR) were determined at 12, 16, 20, 28, and 36 d. Blood and ileal digesta were collected from birds in 10 replicate pens of each treatment at 12, 16, 20, and 36 d to evaluate plasma carotenoid and nitric oxide concentrations and determine nutrient AID and IDE. Jejunal samples were taken at 12, 20, and 36 d for morphological measurements. Oocyst shedding in VAC birds was confirmed by increased oocyst counts and decreased carotenoid concentrations (P < 0.05) when compared with PC birds, with no differences (P > 0.05) in nitric oxide concentrations. At 20 d, BWG and FI were lowest (P < 0.05) in VAC birds, intermediate in NC birds, and highest in PC birds, with no differences in FCR (P > 0.05). By 28 and 36 d, FCR was higher (P < 0.05) for VAC and NC birds but BWG and FI of VAC birds were similar (P > 0.05) to PC birds. At d 12, IDE and AID of nitrogen and ether extract were lower (P < 0.05) in VAC birds than PC birds. At d 16, AID of nitrogen was similar (P > 0.05) between PC and VAC birds, whereas AID of ether extract remained lower in VAC birds than PC birds. No differences in AID of nutrients or IDE were observed (P > 0.05) between VAC and PC birds at 20 or 36 d. No differences (P > 0.05) in jejunal morphology were observed at any time point. Overall, VAC elicited a transient reduction in AID and IDE, particularly for lipids, that diminished by d 20.

“…Additionally, the adequate levels of nutrients present in the basal diet, mainly Ca and P, may influence the results since the efficacy of vitamin D and its metabolites is dependent upon the availability of nutrients [26,27], or presence of intestinal infection. Indeed, Oikeh et al [16] showed that coccidiosis infection reduces the plasma concentration of 25(OH)D 3 at least up to 12 days after the infection. Therefore, due to the constant intestinal challenges faced by the poultry industry more bioactive sources of vitamin D supplemented throughout the life of the birds may be necessary to maximize the intestinal absorption, as observed by Leyva-Jimenez et al [11].…”

“…The mTOR pathway controls protein synthesis by phosphorylating translational regulators, which in turn enhances mRNA biogenesis [14]. Nevertheless, 25(OH)D 3 supplementation improve different aspects of the intestinal physiology, immunology, and microbiology in broilers [11,[15][16][17].…”

The present study aimed to determine the effect of different times of supplementation of 25-hydroxycholecalciferol (25(OH)D3) in broiler chickens on the performance, carcass and cuts yield, bone resistance, plasma concentration of 25(OH)D3, and expression of the mTOR gene. The treatments were a control diet (CD) supplemented with 3000 IU vitamin D3/kg of feed from 1 to 46 d, or the CD + 2760 IU (69 mcg) of 25(OH)D3/kg of feed from 1 to 21 d, from 1 to 35 d, or from 1 to 46 d. The period of supplementation of 25(OH)D3 did not affect the growth performance of broilers, but the breast meat yield was linearly increased in response to increasing days of supplementation (p < 0.05). Birds supplemented with 25(OH)D3 at the time of the analysis showed an increase (p < 0.05) in the plasma concentration of 25(OH)D3 when compared to non-supplemented birds. The mTOR gene expression (p < 0.05), and breast protein deposition (p < 0.05) presented a quadratic response related to the supplementation period of 25(OH)D3. The fat content of the breast linearly decreased (p < 0.05) as the period of supplementation was extended. The results also showed a positive linear correlation between mTOR expression and 25(OH)D3 plasma levels (r = 0.593; p < 0.05).

The aim of this research was to examine the synbiotic interactions of garlic (Alium sativum) and Lactobacillus achidophilus on the characteristics of broiler chicken bones. The material used was 144 broiler chickens strain Cobb unsexed 7 days old with initial body weight 45.68 ± 1.52 g, in a completely randomized design with 3 treatments and 8 units each unit consisting of 6 birds. Treatments applied of addition synbiotic was T0: control feed (without synbiotics); T1: control feed + 2ml synbiotic; T2: control feed + 4ml synbiotic. Parameters observed were the length and weight of the tibia, femur, bone strength and bone Ca mass. The data were statistically analyzed by Analysis of varince with F test and if there significantly effected by tretment, continues by Duncan test. The results show that the use of synbiotics up to 4ml level did not significantly (P> 0.05) to the length of the femur, tibia and femur weight, and calcium mass, but significantly increased (P<0.05) tibia length, tibia and femur bone strength . The conclusion is synbiotic extract from garlic extract and Lactobacillus achidophilus as much as 2 ml / kg ration in broiler chicken rations is enough to improve the characteristics of broiler chicken bones.
