Background: Optimizing the intestinal integrity of poultry flocks through a comprehensive index measure, such as the intestinal integrity (I2) index, could help to promote sustainable production in the poultry industry. The I2 index is a tool for assessing the intestinal health of flocks based on flock level health and performance data, captured by Elanco Animal Health’s global surveillance system, i.e., the Health Tracking System (HTSi). The objectives of this study were to evaluate the relationships between the proposed I2 index and each of the following four performance parameters: average daily gain (ADG), feed conversion ratio (FCR), European production efficiency factor (EPEF), and percent livability; and compare the ability of the proposed I2 index to predict these performance parameters with the current I2 index. Results: The proposed I2 index was found to produce a greater range and increased variation in flock level I2 index scores as compared with the current I2 index. The proposed I2 index was found to predict the four performance measures at least as well as the current I2 index, and the results suggested that the proposed I2 index could be superior at predicting ADG, EPEF, and percent livability. Conclusion: Our results highlight the strength of data-driven approaches in the development and improvement of comprehensive health metrics.

ABSTRACTThe development of subcutaneous fat as measured by ultrasonics was determined in 28 Angus, 46 Hereford and 42 Charolais bulls, performance-tested on a barley/grass diet. The ultrasonic fat measurements were then examined for possible relationships with feed intake, growth rate and feed conversion efficiency. There were apparent breed differences in the rate of increase in subcutaneous fat thickness with changing live weight but ultrasonic measurements bore little relationship to performance parameters within any of the three breeds tested.

<p>The experiment was conducted to determine the effect of CPO protected with formaldehyde on digestibility and performance of thin tail sheeps. Fifteen local male lambs aged 9-12 months, were divided into 3 groups of ration treatment. The first group received only the basal ration (R0), the second group received the basal ration and 3% CPO (R1), while the third group received the basal ration and 3% CPO protected with 2% formaldehyde (R2). The data were analyzed by Completely Randomized Design with oneway pattern. The different of treatments were tested by Duncan’s New Multiple Range Test. The results showed that addition CPO protected with formaldehid (R2) in the sheeps diet did not affect dry matter and organic matter intake, dry matter and organic matter digestibility, average daily gain (ADG), but significantly (P&lt;0.01) increase feed conversion rate. It can be concluded that CPO protected with formaldehyde gives more advantage on feed conversion aspect.</p><p>(Key words: Thin tail sheeps, Crude palm oil (CPO) protected with formaldehyde, Digestibility, Performance)</p>

Aims: In this experiment, evaluation of intake, digestibility and growth performances of local growing bulls by feeding Jumbo-green, Para and German grass based on Index (Mf) of Maize are considered and ranked this fodder accordingly. Study Design:  Completely randomized block design. Place and Duration of Study: Bangladesh Livestock Research Institute (BLRI), Savar, Dhaka, between July 2016 and September 2016. Methodology: Biomass production efficiency (Xddm), animal production efficiency (Xap), CH4 emission deduction efficiency (XCH4) and benefit to cost efficiency (Xbc) was considered to identify the biological characteristics of four fodders. Statistical analysis was done through SPSS-17 to evaluate the intake, digestibility and growth of animal. Rank of each fodder was calculated through the equation of Maize index (Mi) = (Xddm + Xap + XCH4 + Xbc)/4. Results: Aggregation of four arithmetic average efficiency; Jumbo-green, Para and German got 0.42, 0.40 and 0.72 point out of 1.0 point of Mi, respectively. Among four fodders German grass performed best in terms of average daily gain (107 gm/d) and feed conversion ratio (46.9) compared to maize silage (64 gm/d & 58.4, respectively). Weight loss of bulls fed Jumbo and Para has occurred unexpectedly. Conclusion: In combination of mathematical calculation and statistical evaluation, the rank of four fodders measured as Maize>German>Jumbo-green>Para.

The red macroalgae (seaweed) Asparagopsis spp. has shown to reduce ruminant enteric methane (CH4) production up to 99% in vitro. The objective of this study was to determine the effect of Asparagopsis taxiformis on CH4 production (g/day per animal), yield (g CH4/kg dry matter intake (DMI)), and intensity (g CH4/kg ADG); average daily gain (ADG; kg gain/day), feed conversion efficiency (FCE; kg ADG/kg DMI), and carcass and meat quality in growing beef steers. Twenty-one Angus-Hereford beef steers were randomly allocated to one of three treatment groups: 0% (Control), 0.25% (Low), and 0.5% (High) A. taxiformis inclusion based on organic matter intake. Steers were fed 3 diets: high, medium, and low forage total mixed ration (TMR) representing life-stage diets of growing beef steers. The Low and High treatments over 147 days reduced enteric CH4 yield 45 and 68%, respectively. However, there was an interaction between TMR type and the magnitude of CH4 yield reduction. Supplementing low forage TMR reduced CH4 yield 69.8% (P <0.01) for Low and 80% (P <0.01) for High treatments. Hydrogen (H2) yield (g H2/DMI) increased (P <0.01) 336 and 590% compared to Control for the Low and High treatments, respectively. Carbon dioxide (CO2) yield (g CO2/DMI) increased 13.7% between Control and High treatments (P = 0.03). No differences were found in ADG, carcass quality, strip loin proximate analysis and shear force, or consumer taste preferences. DMI tended to decrease 8% (P = 0.08) in the Low treatment and DMI decreased 14% (P <0.01) in the High treatment. Conversely, FCE tended to increase 7% in Low (P = 0.06) and increased 14% in High (P <0.01) treatment compared to Control. The persistent reduction of CH4 by A. taxiformis supplementation suggests that this is a viable feed additive to significantly decrease the carbon footprint of ruminant livestock and potentially increase production efficiency.

In the first of two factorial experiments, 26-week-old crossbred pullets were fed for a period of 24 weeks diets with lucerne either in the form of meal or crumbled pellets, with or without 25 p.p.m. furazolidone and with 1 p.p.m. of either G-apo-8'-carotenoic acid ethyl ester or canthaxanthin. In the second experiment, crossbred hens aged 58 weeks were fed for a period of 16 weeks either triticale or wheat, or triticale plus wheat or wheat plus oats on a free choice basis with a concentrate mixture containing either 0 or 333 p.p.m. of ethoxyquin. Lucerne pellets reduced rate of egg production, hen-housed production, efficiency of feed conversion and the income per bird. It increased feed intake by 3.2 per cent and egg yolk colour by 2 per cent. Furazolidone increased hen-housed production and efficiency of feed conversion but had no effect on egg yolk colour. Pullets given diets with canthaxanthin laid eggs with higher yolk colour scores and specific gravity and converted feed more efficiently than those given the diets with G-apo-8'-carotenoic acid ethyl ester. The depressive effect of lucerne pellets on egg production and feed conversion was overcome by both furazolidone and canthaxanthin. Triticale reduced the concentration of oxycarotenoids in egg yolks, Hens given triticale tended to eat more, convert feed less efficiently and gained less liveweight than those given wheat, but rate of egg production and egg weight were unaffected. The performance of hens given triticale plus wheat fell between that of those given either triticale or wheat as the sole cereal. Hens given wheat plus oats tended to lay fewer but heavier eggs with lower yolk colour and gained less liveweight than those given wheat. Ethoxyquin increased the concentration of oxycarotenoids in egg yolks but had no effect on other production traits.

Abstract Plant extracts contain active molecules called pronutrients that could replace antibiotic growth promoters (AGP) in order to improve intestinal integrity, optimize feed utilization and consequently, increase productive performance. The purpose of this study was to evaluate the effect of a mixture of pronutrients on hematological parameters, serum cytokins regulation, intestinal morphology, organs weight and productive parameters. The trial was conducted with 480 one-day-old male broilers of the Ross AP 308 divided into 3 groups: Group CON - Basal diet only, Group AB supplemented with bacitracin methylene disalicylate and Halquinol continuously, and Group PR with a mixture powder of pronutrients, respectively. The experiment lasted up to the 35th day of age. 3 % of crude soybean was added to all basal diets as a challenge for intestinal integrity. All data were statistically analyzed using ANOVA and P value less than 0.05 was set as statistically significant and 0.05 &lt; P &lt; 0.1 as tendency. A decrease of all serum cytokines (IL-1β, IL-6, IL-8, IL-10) in supplemented broilers with pronutrients was observed. The intestinal morphology parameters were better (length and villi depth) and performance parameters such as feed intake, body weight and feed conversion rate (FCR) throughout the trial were improved in broilers supplemented with pronutrients (P &lt; 0.05). Dietary supplementation with a natural additive based on pronutrients demonstrated to be an effective alternative to AGP to improve intestinal morphology, productive performance and regulating hematological and immune values in broilers challenged with diets containing raw soybean.

Present study was conducted to investigate the effect of different floor space allowances on performance and behavior of Beetal kids from 3 to 6 months of age. Twenty four spring born Beetal kids (3 month old) were randomly divided in to four groups (n=6 each group) on the basis of space allowances i.e. 0.6 m2, 0.7 m2, 0.8 m2 and 0.9 m2 covered area and 1.2 m2, 1.4 m2, 1.6 m2 and 1.8 m2 open area per kid. The results indicated that most of the performance parameters i.e. body weight (BW), average daily gain (ADG) and feed conversion ratio (FCR) were marginally higher with higher space allowance, but these did not differ statistically. However behavioural activities like moving, exploring pen, grooming and resting were significantly higher (p < 0.05) in large space allowance groups whereas, eating, standing and negative social interactions were significantly better (p < 0.05) in lower floor space allowance groups. It is concluded that the increase in floor space allowance had favorable effect on the performance and behavior of Beetal kids.

A 32-day experiment was conducted to study the effects of supplementation of phytase enzyme, Ronozyme® HiPhos (DSM Nutritional Products, Basel, Switzerland), on the production parameters, water intake, intestinal histomorphology, carcass characteristics and bone mineralization of broiler chickens. A total of 1920 one-day-old Cobb 500 broilers were randomly allocated to one of three treatments, each comprising eight replicate cages (eight replications per treatment) with 80 birds per cage. Dietary treatments were created using a standard commercial diet as the positive control (CON); reducing the nutrient content of the CON diet with values similar to the matrix values of 1500 FYT (phytase units) Ronozyme® HiPhos to create the negative control diet (NEG); and supplementing the NEG diet with 1500 FYT/kg Ronozyme HiPhos to create the phytase diet (HiPhos). Supplementation of the NEG diet with HiPhos significantly improved average daily gain (ADG), feed conversion ratio (FCR), bodyweight (BW) at slaughter and the European production efficiency factor (EPEF) of broilers compared with those in the NEG treatment group, but had no effect on total feed intake, water intake, villi height, crypt depth, dressing percentage, portion yields, pH of the meat or colour of the meat. Fat-free bone ash percentage and tibia breaking strength of broilers in the HiPhos treatment group were intermediate to broilers in the NEG and CON treatment groups. Results from the study proved that broilers could be supplemented with HiPhos phytase without detrimental effects on growth parameters, bone mineralization, carcass characteristics and water intake.Keywords: Bone breaking strength, chickens, phosphorus, villus height, weight gain

In this study, the possibility to control enzootic pneumonia by spraying mild organic acids in fatteners' buildings was investigated. In a farm with enzootic pneumonia, two groups, each of 120 weaned pigs, were housed in 2 separate rooms. With the pigs inside, the rooms were being sprayed once a week, for a total period of 20 weeks (up to the end of fattening period), either with a mixture of organic acids (1st room= AML-pigs), or with water (2nd room= placebo control pigs). Groups were compared with each other with respect to pigs' health status, mortality, performance parameters (average daily gain, feed conversion ratio) and the presence of specific lesions and pathogens in their lungs. It was shown that the incidence of coughing and the mortality in the AML-pigs were lower (10% and 3.25% respectively) compared to placebo controls (25% and 8.26% respectively). At the age of 70,120 and 165 days, the AML-pigs were 1.9 kg, 2.85 kg and 4.75 kg heavier, respectively, compared to controls (P< 0.001). Also, the pigs of the acid treated group have performed better than the controls with respect to average daily gain (674 g and 640 g respectively) and feed conversion ratio (3,00 and 3,14 respectively) (P<0.05). Lung lesions, characteristic for enzootic pneumonia, were detected in 37.5% of the AML-pigs and in 57.5% of placebo controls. Bacteria in the lungs, possibly complicating the disease, were isolated from more pigs of the control group compared to the acid-treated group. Finally, no clinical side effects following each application of the product were observed. The results of the present study show that, spraying of mild organic acids in a Mycoplasma hyopneumoniae-affected pig farm can be used for controlling the disease and improving performance parameters.

SummaryThe efficacy of the probiotic feed additive, Calsporin® (CAL; Bacillus subtilis C-3102), included in broiler diets at 50 mg/kg was evaluated using statistical meta-analysis of data from four different studies conducted using broilers from day-old to market weight at 42 days of age. The body weight, average daily gain, feed intake, feed to gain ratio, mortality and European Production Efficiency Factor (EPEF) data from each experiment were tested for homogeneity between trials before being pooled and analysed in combination to determine whether benefits were consistent independent of trial site and conditions. CAL supplementation significantly improved weight gain (P = 0.0037) between 1 and 21 days of age (3.3%) and feed conversion ratio (P = 0.0492) between 22 and 42 days of age (3.0%). Over the entire experimental period (day 1 to day 42 of age), broilers fed the CAL diets had significantly better (P = 0.0142) feed conversion (2.6%) and higher (P = 0.0062) EPEF (4.6%) compared to the controls. Birds fed diets supplemented with CAL were 1.6% heavier than controls at 42 days of age, a near-significant trend (P = 0.0558). The results demonstrated that CAL in broiler diets, added at an inclusion rate of 50 mg/kg, can be beneficial in terms of broiler performance.
