This program can be used for up to 7-10 days after arrival. Then switch back to the regular step-down lighting program. Using this lighting program has the following advantages:<\/p>

  • Chick behavior is synchronized; they rest or sleep at the same time.<\/li>
  • Weak chicks will be stimulated by stronger ones to move as well as to eat and drink.<\/li>
  • The behavior of the flock is more uniform and evaluating the flock is much easier.<\/li>
  • Chick mortality will decrease.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    In open houses is not easy to implement the intermittent lighting program. If this cannot be applied, 22-24 hours of light during the first 2\u20133 days is common practice. Providing this dark period to allow the chicks to rest is highly recommended.<\/p>

    In a dark house the light level should be lower than 3 lux whenthe light-proof system is set. In other words, it must be completely dark.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    The temperature should be between 34\u201336 \u00b0C for the first few days (see table).<\/p>

    • Correct temperature: Chicks will be well distributed and active<\/li>
    • Low temperature: Chicks will group together and sound stressed.<\/li>
    • High temperature:\u00a0Chicks will group in the coldest places, are inactive and pant.<\/li><\/ul>

      Temperature recommendations<\/strong><\/p>

      • Cage air temperature: 34\u201335 \u00b0C<\/li>
      • Paper and\/or litter temperature: > 32 \u00b0C<\/li><\/ul>

        Concrete\/ground: > 28 \u00b0C<\/p>

        Pasted vents may indicate a too high or too low temperature.<\/p>

        The temperature management in\u00a0cage brooding is more critical than floor\u00a0because chicks can\u2019t look for warmer or cooler spots.<\/p>

        After two or three days, decrease the temperature by 0.5 \u00b0C every day.\u00a0Be aware that the best indicator is chick behavior and cloacal temperature.\u00a0Check the flock every time you change your settings. If the house temperature is not uniform, take corrective measures by changing heaters and ventilation parameters. When housing the chicks, follow these recommendations:<\/p>

        • Place the smallest chicks in the hottest areas or cages.<\/li>
        • Place the youngest chicks in the hottest areas or cages (if the flock is arriving over several days).<\/li>
        • During the first 10 days avoid placing chicks in very hot spots (near the heaters) or in very cold spots.
          If most of the chicks are from a young flock (less than 27 weeks), increase the objective temperate 1 to 2 \u02daC (1,8 to 3,6 \u02daF).<\/li>
        • Place the males together with females in case of Brown Nick and white breeders when males are dubbed.<\/li>
        • In case of non-dubbed white males, keep them separate for the first 6\u20137 weeks or until you recognize the secondary sexual characteristics, and after culling all sexing errors.<\/li>
        • If males are from a young PS flock (less than 27 weeks) keep them separate for the first 5 weeks in the warmer place of the house (when necessary, add females to stimulate activity).<\/li>
        • Cages: is necessary to place only comb treated males.<\/li>
        • Leave the extra males separate in pen or cages.<\/li>
        • In countries where dubbing is not allowed, an option is to wing-band the white males.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

          Set the height of the drinkers so the chicks can drink easily 360-activated nipples are preferable in rearing houses. If not available, and especially with infrared beak treated chicks, we recommend using cups or other extra drinking system at a ratio of 80 to 100 birds per extra drinker. Especially important having extra drinkers when brooding on floor. Reduce the water pressure in the drinking system to create a hanging drop at chick eye level. Follow manufacturer recommendations for flow rate. Trigger the nipples or cups during the first 3\u20134 days to encourage chicks to drink. Important to keep all the time the water temperature between 20 to 25\u02daC (68\u201377\u02daF).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Always perform necropsies of the mortality at arrival and in the first 7 days after placement.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
