Effect of Post Hatch Delayed Access to Feed on Performance, GIT Physical and Histological Development and Yolk Absorption in Young Broiler Chicks

The Effect of Early Post Hatch Feeding Times on the Growth and Development of the Gastrointestinal Tract of Mule Ducklings to Five Days of Age

“…The presence of exogenous feed in the gastrointestinal tract plays a fundamental role in initiating growth during the early post-hatch (Maiorka et al 2003). In this present study, the bodyweight of ducklings fed at the 3 hours post-hatch was significantly higher (p<0.05) than those fed at 24, 36, and 48 hours post-hatch which concurs with the reports of Ganjali et al (2015) in broiler chicks and Loudon et al (2011) in Pekin ducklings.…”

“…31-60.18, 47.77-50.51, and 58.61-75.52 cm for Days one, two, and four; respectively. These results when compared to previous studies showed that the SI length was similar to broiler chickens (Ganjali et al, 2015). The relative jejunal length was highest in the present study, followed by ileal length; this trend observed was similar to the findings of Applegate & Lilburn (1999) for turkey poults.…”

“…This observation may be attributed to the availability of energy and protein at an early stage which was used for the development of the intestine. The lower GIT organ weights observed in the other treatment groups (24, 36, and 48 hours) may be as a result of feed deprivation (Maiorka et al, 2003;Ganjali et al, 2015).…”

Effect of probiotic and vinegar on growth performance, meat yields, immune responses, and small intestine morphology of broiler chickens

“…Morphometric indices included were villus height (VH) from the tip of the villus to the crypt, crypt depth (CD) from the base of the villus to the submucosa, villus width (VW; average of VW at one-third and twothirds of the villus) and muscular thickness (MT) from the submucosa to the external layer of the intestine (Ebrahimi et al 2017). The villus surface area (VSA) was calculated according to the Formula 1 (Gangali et al 2015).…”

Hindi Palazlarının Yumurtadan Çıkışı Takiben Nakil Kutularında Hemen Yemlenmesinin Palazlarda Gelişim Performansına Etkisi

“…In another research Halevy et al (2003) tried a longer fasting for birds and imply that a 48 hour fasting period after hatch ends in a lower live weight at 19 days. Ganjali et al (2015) examined 6, 12, 18 hour delayed feeding in terms of performance and histological findings in small intestines. It has been reported that those who fasted for 6 hours after hatch showed better performance at 10 days of age in terms of live weight and live weight increase than those starved for 12 and 18 hours.…”
