Serum chemistry and gut morphology of two strains of broiler chickens to varying interval of post hatch feeding

Abstract

This trial was carried out to determine the responses of two broiler strains of chicken to different post-hatch access to feed. 180-day old chicks (Arbor acre and Marshal strains) with initial weight range of 39.36–42.24 g were used for this study. Each strain was divided on weight equalization into three treatment groups consisting of three time-periods with access to feeds (4 h, 24 h, 48 h) post hatch in a 2 × 3 factorial experiment after which they were fed ad-libitum. Thirty (30) birds were assigned to each treatment which comprised of three replicates of ten birds. Data collected on serum biochemical constituents and gut morphology were measured and subjected to analysis of variance in a randomized design. The Marshal strain recorded a higher (p < 0.05) final live weight (2420.00 g/bird) than the Arbor acre strain (2218.30 g/bird). Birds fed at 4 h and 24 h post-hatch recorded higher (p < 0.05) final live weights (2402.00 and 2391.00 g/bird) than those fed at 48 h post-hatch (2133.00 g/bird). Interaction effects showed that the Marshal strain fed at 4 h post-hatch had the highest (p < 0.05) final live weight (2594.00 g/bird). Highest (p < 0.05) serum total protein and albumin (37.3 and 22.8 g/l) were recorded in birds fed at 4 h post-hatch when assessed at 4 weeks of age. Furthermore, birds fed at 4 h and 24 h post-hatch recorded higher (p < 0.05) serum total protein and albumin than those fed at 48 h post-hatch. Birds fed at 4 h post-hatch recorded the highest (p < 0.05) duodenal villus height at 4th and 8th week of age and highest (P < 0.05) jejunal villus height when assessed in the 2nd week of age. It was concluded that Marshal strain fed at 4 h post-hatch elicited the highest growth performance and the most developed gut morphological features.

Performance, blood profile and gut morphometry of broiler chickens fed diets supplemented with Yohimbe (Pausynistalia yohimbe) and Larvacide

“…At the starter phase, the values of Serum biochemical indices recorded were within range with those reported by Adeleye et al. (2018) who evaluated the serum chemistry of broiler chickens at varying intervals of post hatch feeding although, uric acid and creatinine values were slightly higher.…”

Effect of broiler genetics, age, and gender on performance and blood chemistry

“…It has been reported that higher serum protein and lower globulin values were observed in more efficient (lower FCR) birds due to superior utilization of nutritional protein ( Adeleye et al., 2018 ). These results agreed with the present study where lower FCR and greater BW of Ross male broilers was associated with lower GLOB values, when compared to Cobb broilers; and greater TP values when compared to female broilers.…”

“…(2005) using hematological profiling. While other studies have focused on hematological and biochemical reference ranges only with regard to a specific time, strain, region, or sex ( Adeleye et al., 2018 ; Al-Nedawi, 2018 ; Nanbol et al., 2016 ), others have studied the effects of various treatments on hematology including feeding allopurinol to reduce uric acid levels ( Klandorf et al., 2001 ) or the effect of heat stress on similar blood biomarkers ( Wang et al., 2018 ). Regardless of the objective, these hematological profiling experiments have occurred with increasing frequency.…”

Intestinal Development and Histomorphometry of Broiler Chickens Fed Trichoderma reesei Degraded Date Seed Diets

“…Morphometric results of the duodenum, jejunum, and ileum in broilers on day 42 of the experiment revealed that DDP treatment enhances the health of the digestive tract by altering the villus height and crypt depth. Absorption of nutrients is promoted by longer villi and shallower crypts with greater surface area, which activates maturation of the intestinal cells and digestive enzyme activity (35,36). The crypt is the production site where divisions of stem cells occur to allow villus renewal.…”
