In this study Comparative production performance of three broiler strains namely, Hubbard, Vencobb and Vencobb-400 was explored in tropical summer season of Eastern Uttar Pradesh state of India. Experiment was conducted on 450 broiler chicks, 150 chicks of each strain with three replications of 50 birds each. The performance of the broiler strains were measured in terms of feed intake, body weight gain and FCR, dressing and mortality percentage. Their performance on the aforementioned criteria was observed, three times, at the age of 14 days, 28 days and 42 days during the experimental period. It was observed that there exists a significant difference in performance in terms of feed intake, live weight, body weight gain and FCR among the three broiler strains during the experimental period and even at each stage of experimental age of 14, 28 and 42 day. The mortality was also significantly different in each strain and at each stage of experimental age. There was a significant difference in the dressing percentage among the three strains of broilers at the age of 42 days. Results indicated that Vencobb-400 performed best followed by the Hubbard strain. Therefore, both Vencobb-400 and Hubbard broiler strains may be recommended as economic and more suitable for rearing in tropical summer season of Eastern Uttar Pradesh of India.

Two groups of one-day-old Peking ducklings (Groups I and II, 12 birds/group) were inoculated orally withBrachyspira pilosicoliand two groups withB. alvinipulli(Groups III and IV, 12 birds/group). T-2 toxin was added to the feed of Groups II and IV in a dose of 1 mg/kg of feed. Groups V and VI served as uninfected control groups (ducks of Group VI received T-2 toxin). The body weight gain of the ducks was measured and clinical signs were monitored continuously. The birds were sacrificed and necropsied on days 7, 14, 21, and 28 post infection (PI). The liver, spleen, kidney, thymus, bursa of Fabricius, ileum, caecum and colon were examined histologically. Culturing ofBrachyspiraspp. and immunohistochemistry were performed from the sampled parts of the intestines as well. No gross pathological or histological lesions that could be associated withB. pilosicoliorB. alvinipulliwere detectable in the intestinal mucous membrane including the colonised intestinal glands. Mortality did not occur during the experimental period. Decrease in body weight gain was significant in the T-2-toxin-treated groups, and it was slight (not significant) in theBrachyspira-infected groups. Crust on the beaks, necrosis, crusting and ulceration in the mucous membrane of the oral cavity and on the skin of the feet, atrophy of the thymus and bursa of Fabricius due to the effect of T-2 toxin, accompanied by lymphocyte depletion, were observed. These lesions were most prominent on days 14 and 21 PI but were seen on day 28 PI as well. Immunohistochemical detection and reisolation ofB. pilosicoliandB. alvinipulliwere successful on days 7, 14, 21 and 28 days from different segments of the intestine of certain birds, but no significant difference was observed in the colonisation rate between the T-2-toxin-treated and the untreated groups.

In the present feeding trial, responses of laying hens, kept at high ambient temperature, to various dietary ratios of linoleic acid (LNA) to α-linolenic acid (ALA) and vitamin A levels on performance and egg characteristics were evaluated. A total of 360, 40-wk-old, Leghorn laying hens were fed on diets with various combinations of canola oil and linseed oil to achieve LNA to ALA dietary ratios of 20:1, 10:1, 4:1, 2:1, 1:1 and 1:2, each supplemented with 3000 IU or 10000 IU vitamin A/kg of diet. The diets were fed in a 6×2 factorial Completely Randomized Design that continued for 12 weeks. Feed intake, weight gain, egg production and egg quality traits were recorded during the trial. Decreasing dietary LNA to ALA ratio in the diet affected negatively (P<0.05) on body weight gain and yolk percentage in laying hens. While, feed intake, hen-day and hen-housed egg production, feed conversion ratio (FCR) per dozen of eggs and shell quality remained unaffected (P>0.05) by dietary treatments, with the exception of FCR per kg eggs, egg weight and egg-shell thickness which responded significantly (P<0.05) to various dietary treatments. Although the dietary ratio of LNA to ALA of 4:1 or less could produce eggs by the hens with desirable quantities of n-6 and n-3 poly unsaturated fatty acids – that are characteristics of functional diets – the performance of laying hens in terms of body weight gain and egg-yolk percentage was slightly compromised.

Abstract Background This study evaluated the effects of supplemental xylanase and xylooligosaccharides (XOS) in a corn-soybean meal (SBM)-based diet on growth performance and intestinal health of broilers. A total of 288 day-old chicks (Cobb 500) were allocated to 36 floor pens (8 birds/pen) equally in 9 dietary treatments in a 3 × 3 factorial arrangement. The treatments were combinations of 3 levels of xylanase (0, 0.005% and 0.01% Econase XT) and 3 levels of prebiotics (0, 0.005% and 0.01% XOS) added to basal mash diets formulated in three phases (starter, d 0–14; grower, d 15–28; finisher, d 29–42). The feed intake and body weights were recorded weekly. On d 42, ileal sections were collected for histomorphometric and gene expression analysis, and cecal content was collected for determining short-chain fatty acids (SCFA) and microbiota. Results Xylanase linearly (P < 0.01) increased the average daily gain (ADG) in both the finisher and total period and the final body weight gain (FBWG, 2940 & 2932 vs. 2760 g) of broilers. XOS did not significantly increase either ADG or FBWG (P > 0.05). Supplemental xylanase and XOS did not affect average daily feed intake and feed conversion ratio (P > 0.05). Xylanase and XOS did not change villus height (VH) or crypt depth (CD) ratio (P > 0.05). However, xylanase exhibited a trend (P = 0.097) on VH:CD ratio. The inclusion of 0.01% XOS without xylanase increased the level of IL-10 (a marker of anti-inflammatory cytokine) and IL-4 (a T-cell differentiation cytokine) genes compared with control (P < 0.05). The acetate production was increased by xylanase (P < 0.01) and XOS (P < 0.05) without an additive effect. Xylanase increased total SCFA (P < 0.01) while XOS had a tendency to increase (P = 0.052). Alpha and beta diversity of microbiota among treatments were not different (P > 0.05). However, the mean proportion of family Ruminococcaceae was increased by the supplemental 0.01% xylanase (P < 0.01). Conclusion It can be concluded that XOS can enhance cecal fermentation, while xylanase can increase the body weight gain along with the fermentation metabolites in the ceca of broilers fed the corn-SBM-based diet but the effects may not always translate into an improved mucosal absorptive capacity and a better feed efficiency.

The present study was conducted to evaluate encapsulated essential oils as an alternative anticoccidial in coccidiosis vaccine challenged broiler chickens. A total of 600 day-old male broiler chicks were provided with no-added corn-soybean meal-based control diet or diets that contained either salinomycin or EO at 60 and 120 mg per kg of diet. On day 21, half of the control groups were orally challenged with a coccidiosis vaccine at 25 times higher than the recommended vaccine dose. During 22 to 28 days (i.e., one-week post coccidiosis vaccine challenge), the challenged chickens had decrease (P &lt; 0.05) in body weight gain and feed intake but increase in feed conversion ratio compared with the non-challenged, na&iuml;ve control chickens. However, dietary EO significantly counteracted (P &lt; 0.05) coccidiosis vaccine-induced depression in body weight gain and feed intake. Increasing dietary EO linearly decreased (P &lt; 0.05) the concentrations of the volatile fatty acids. Dietary SAL and EO affected gut morphology in chickens at 20 days posthatch. Increasing dietary EO linearly (P = 0.073) increased serum catalase activity. Collectively, our study shows that dietary EO increased coccidiosis vaccine-induced growth depression and altered gut physiology in broiler chickens.

The present study was conducted to evaluate the encapsulated essential oils (EEO) as an alternative to anticoccidials using a coccidiosis vaccine challenged model in broiler chickens. A total of 600 one-day-old male broiler chicks were provided with no added corn/soybean-meal-based control diet or diets that contained either salinomycin (SAL) or thymol- and carvacrol-based EEO at 60 and 120 mg per kg of diet. Before challenge at 21 days, each treatment had 10 replicates except for the no-added control group, which had 20 replicates. On day 21, half of the control groups were orally challenged with a coccidiosis vaccine at 25 times higher than the recommended vaccine dose. During 22 to 28 days (i.e., one-week post coccidiosis vaccine challenge), the challenged chickens had a decrease (P < 0.05) in body weight gain and feed intake but an increase in feed conversion ratio compared with the non-challenged, naïve control chickens. However, dietary EEO significantly counteracted (P < 0.05) coccidiosis-vaccine-induced depression in body weight gain and feed intake. Inclusion of dietary EEO linearly decreased (P < 0.05) the concentrations of the volatile fatty acids. Dietary SAL and EEO affected gut morphology in chickens at 20 days post-hatch. Dietary EEO linearly (P = 0.073) increased serum catalase activity as the inclusion level increased. Collectively, our study shows that dietary EEO increased coccidiosis-vaccine-induced growth depression and altered gut physiology in broiler chickens. Our study adds to the accumulating evidence that dietary EEO is proven to be an effective alternative to anticoccidials for broiler chickens.

Fungal fermented protein (FFP) was the alternative feedstuff from Aspergillus niger and can be an interesting choice in poultry diets because these product was containing 20.49 % of crude protein and high leucine (0.58 %), phenylalanine (0.58 %) and lysine (0.38 %) and contained no aflatoxin. The experiments were performed using a completely randomized design with 6 treatments and 3 replications employing eight 1-day-old, mixed sex muscovy ducks (Cairina moschata) per experimental unit. The control birds were fed with a basal diet whereas the test birds were fed with FFP at 5, 10, 15, 20 and 25 % of diet. Feed and water were provided ad libitum. The feed intake of the starter showed no significant difference while the grower and finisher had higher feed intake with higher levels of FFP. In contrast, the high level of FFP yielded the lower final body weight and body weight gain, resulting in the high feed conversion ratio (4.38). For the performance of overall period, the ducks fed with 20 % FFP had higher average daily gain (29.40 g/b/d), body weight gain (2,471 g/b) and feed conversion ratio (3.63). No deaths were found in any pens and the ducks remained in good health.

The needs for animal protein increase significantly as the number and prosperity level of people increase. Ducks are water poultry that can be used to supply meat and eggs to fulfill people need for protein.    Ducks are the second most important egg producers after chickens.  In Indonesia, duck eggs share about 30-40% of total egg supply (Suharno 2002).  This study was aimed at assessing the production performance of male local ducks fed torch ginger flower (Etlingera elatior) solution included in commercial ration.  Male local ducks aged 2 weeks with average initial body weight of 450 g were used.  Commercial feed was mixed with torch ginger flower solution.  A completely randomized design with 4 treatments and 3 replicates was used.  Treatments consisted of four levels of torch ginger flower solution, namely 0, 2.5, 5.0, and 7.5%.  Data were subjected to an analysis of variance and measurements were taken on feed intake, body weight gain, feed conversion, and mortality rate.  Results showed that no significant differences (P>0.05) were found in all parameters measured.  The average feed intake was 4037.67±205.748 g, body weight gain was 1034.79±129.14 g/head, and feed conversion was 3.94±0.45.  The mortality rate was found to be 0% indicating no bird was found died in all treatment groups. Provision of commercial feed with a mixture of a solution of interest ginger flower is not able to improve the performance of male local ducks.Key words: animal protein, water poultry, feed intake, body weight gain, feed conversion.

Two trials were conducted to determine feed color effects on broiler performance. A completely randomized design was used. Trial 1 included four treatments: control (complete broiler starter diet), red, green, and blue; and Trial 2 included four treatments: control, orange, yellow, and purple. Each trial had 4 treatments with 4 replicates (60 birds/treatment) fed to 240 male Cobb 500 broilers during a 21 d grow out. Data were analyzed using the GLM procedure. In Trial 1, there were no treatment effects on average body weight, body weight gain, and feed consumption (p > 0.05). Adjusted feed conversion for control (1.23) was less than red (1.27; p = 0.001) and green (1.26; p = 0.009), with blue (1.25; p = 0.056) tending to be different during the experimental period. In Trial 2, there were no treatment effects on average body weight, feed consumption, and adjusted feed conversion during this study (p > 0.05). Body weight gain between d 1 to 14 for purple (490.78 g/bird) was more than orange (467 g/bird; p = 0.013) and yellow (461 g/bird; p= 0.004), with control (474 g/bird; p = 0.052) tending to be different. Results indicate that these feed colors had some, albeit limited, influence on broiler performance parameters.

An experiment was carried out to determine the growth performance and haematological indices of Red Sokoto goats placed on oil palm leaf meal (OPLM)-wheat offal based diet. Six goats aged 12-18 months, weighing 15 – 20kg were randomly assigned to three treatments, comprising two animals each in a Completely Randomized Design. Each animal received 1kg of the diet daily for 56 days and weighed weekly. Results showed that final body weight was significant (P<0.05) with goats on T3 having the highest (21.50kg). The feed intake, body weight gain and Feed Conversion Ratio (FCR) were significantly different (P<0.05). T3 had the highest feed intake (305.35g/d), highest body weight gain (90.84g/d) and the best FCR (3.36). Significant differences (P <0.05) were observed in the Red Blood Cell (RBC), Packed Cell Volume (PCV) and Haemoglobin (Hb) counts, ranging between 3.12 - 4.20x106ml; 23.00 -30.50% and 7.70 - 10.15g/dl respectively with goats on T3 having the highest.  The inclusion of OPLM enhanced body weight gain, FCR, RBC, PCV, and Hb counts of the goats. Therefore the oil palm leaf meal diets are recommended for better goat production. Key word: Growth performance; Oil Palm Leaf meal., Blood profile., Creatinine., Red Sokoto Goat.
