1 OPTIFEED POULTRY Introduction to the consumption of solid feed (starter)

2 Optifeed Poultry: principle Behavior management with sense of smell: Feeding behavior Stress reactions 2 ways: Use of molecules stimulating pleasure center in the brain and/or Memorization of an olfactory ambiance associated with welfare 2

3 Olfaction in broiler 3 rd nasal chamber olfactory epithelium 2 nd nasal chamber 1 st nasal chamber nostril Olfactive structures: the chicken has an olfactory epithelium in the third nasal chamber, and its histological structure looks like the mammal one + sinus Olfactive bulb with various size depending on the species 3 nervous structures involved during olfaction: 1. Trigeminal cranial nerve: smell of irritant product (ex: NH 3 ) 2. Olfactive receptors from nasal epithelium connected to olfactive bulb gustatory buds (retro-nasal olfaction) Source: Roper,

4 Olfaction in broiler: neurological evidence Response to olfactive nerve stimulation is equivalent to the response measured on the rat Olfactive bulb response to exposure to odorous molecules is eliminated after ablation of olfactive nerve without ablation of trigeminal nerve Nervous response depending on the dose Source: Roper,

5 Olfaction in broiler: experimental evidence Anosmic chicks have a reduced ADG compared with controls in the first days of farming: % on standard chickens Source: Tallet et al.,

6 Response: Optifeed Poultry Selective stimulation of appetite center Appetite Impossibility of simultaneous stimulation of stress center X Stress 6

7 Mode of action: stimulation of the appetite center The molecules contained in OPTIFEED stimulates the appetite center. Initiation of hormonal secretions that prepare the organism to absorb nutrients. The animal eat. 7

8 Mode of action: stimulation of the appetite center Feed intake induces a hormonal feed back which stimulates the satiety center. The animal stops eating because the needs of the organism are satisfied. 8

9 Mode of action: stimulation of the appetite center The appetite and stress centers have the same hormonal stimulation ways. It is impossible to condition these two centers simultaneously. 9

10 Olfactive sensation intensity and stimulus intensity Sensation intensity Typical curve giving the evolution of the sensation intensity according to the size of the stimuli (from P. Mac Leod) Optifeed Saturation area Infraliminar area Liminar area Supraliminar area Stimuli intensity 10

11 Composition Original mixture of vegetable extracts: Spices Flavoring substances Vegetable extracts (alkaloids and saponins) 11

12 Benefits BETTER FEED CONSUMPTION Appetite stimulation Reduction of feed intake variations INCREASE IN FEED PALATIBILITY Optimal management of stress periods Improvement of performances 12

13 Conclusion Now, a new product specific for Poultry: Optifeed Poultry KX 96 P1 Sw Dose: 500 g / tone complete feed 13

14 TRIAL N 1 EXPERIMENTAL FARM OF LONDRINA UNIVERSITY - BRAZIL MAI 2012

15 Materials and methods Duration: 48 days (from day 1 to slaughter) Animals: 440 birds, 1 day old, Cobb female 5 groups, 4 replication pens Each pen: 22 birds Slaughtered at 48 days Feed: water and feed ad libtum, experimental diets = minimum requirements recommended by Rostagno et al (2011) Pre-starter: 1 7 days Starter: 7 21 days Grower: days Finisher: days Organization: 5 groups (OPTIFEED POULTRY at 500 g/t) 1: control (without Optifeed Poultry) 2: Optifeed Poultry from 1 to 7 days 3: Optifeed Poultry from 1 to 21 days 4: Optifeed Poultry all the period 5: Optifeed Poultry from 1 to 7 days, and from 42 to 48 days 15

16 Mesures Weight gain per bird: weighed every week Feed intake per bird: for each pen and each group, weekly Feed conversion Viability: dead birds were recorded daily Analysis of variance: Tukey test at 5% significance level except Viability, by chi-sqare test 16

17 Results a, b P<0.05 Optifeed Poultry significantly increased feed intake and performances during the first week. 17

18 Results Treatment Control Optifeed Poultry Weight at 14 days (g) a b Value of p CV % 7.79 At 14 days of age, homogeneity of Optifeed Poultry group is 91.67% while the control is 76.67% (% at the standard weight of the genetic line). Optifeed Poultry demonstrated up to 14 days, be an important tool to improve the initial weight of laying hen. 18

19 CONCLUSIONS OPTIFEED POULTRY at 500 g/t increases significantly weight of broilers on pre-starter period. The use of OPTIFEED POULTRY, at 500 g/t, on period 1 to 7 days and period 42 to 48 days give a interesting result (trend), but not significant (variation between group). Significant Return On Investment (ROI). It confirms that OPTIFEED POULTRY increases feed Intake on 1 day old broiler, increasing weight. 19
