JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY 2020; 62:159-173. [PMID: 32292923 PMCID: PMC7142281 DOI: 10.5187/jast.2020.62.2.159] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/21/2019] [Revised: 11/13/2019] [Accepted: 11/13/2019] [Indexed: 11/20/2022]
Abstract
A 4×2 factorial feeding trial was designed to investigate the effect of
replacing soybean meal (SBM) with cottonseed meal (CSM) in
wheat/sorghum/SBM-based diets fed with or without microbial enzymes in diets on
the performance, visceral organ development and digestibility of nutrients of
broiler chickens. Four graded levels of CSM - none (0%), low (4%, 8%, and 12%),
medium (5%, 10%, and 15%), and high (6%, 12%, and 18%) of complete diets in
starter, grower and finisher, respectively were fed with or without 100 mg/kg of
xylanase and β-glucanase blend. Eight isocaloric and isonitrogenous diets
were formulated using least-cost method to meet the nutrient specifications of
Ross 308 male broilers. Each treatment was randomly assigned to 6 replicates (10
birds per replicate). There were CSM-enzyme interactions (p
< 0.05) on feed intake (FI) and weight gain (WG) in the starter phase. Enzyme
supplementation improved (p < 0.05) feed conversion ratio
(FCR) in the grower and finisher phases, and increased WG in growing and
finishing birds. CSM inclusion reduced (p < 0.05) the weight
of gizzard and proventriculus in starter chicks, while these organs were bigger
(p < 0.05) in the grower phase. The test ingredient
decreased (p < 0.05) small intestinal weight in starter and
grower birds. The CSM increased the absolute weight of thighs
(p < 0.05) while breast meat was increased
(p < 0.01) by enzyme addition. Starch digestibility was
improved (p < 0.01) by enzyme inclusion and decreased
(p < 0.01) by CSM. Enzyme supplementation improved
(p < 0.05) the ileal digestibility of gross energy and
protein. The results demonstrate that CSM can substitute up to 90% SBM in
broiler chicken diets without compromising performance, and the nutritive value
of CSM-containing diets can effectively be improved by enzyme
supplementation.

[PMID: 27536033 PMCID: PMC4983123 DOI: 10.14202/vetworld.2016.723-727] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2016] [Accepted: 06/19/2016] [Indexed: 11/16/2022] Open
Abstract
Aim: The study was undertaken to find out the effect of feeding cottonseed meal (CSM) on performance of hematological and serum biochemical parameters in broiler birds. Materials and Methods: A 6-week biological trial was carried out with 432-day-old Cobb 400 broiler chicks distributed to nine experimental diets with six replicates, each containing eight chicks. The experimental diets were formulated based on total amino acids (BTAA) or based on digestible amino acids (BDAA) with or without iron supplementation with two levels of CSM (2% and 4%) and control diet based on maize – soybean. The whole blood was subjected to hematological studies. The serum samples were analyzed for protein fractions and lipid profiles. Results: The packed cell volume (PCV) value, red blood cell (RBC) numbers, and hemoglobin (Hb) were lower in iron unsupplemented CSM BTAA or BDAA diets than the control (33.86-35.54 vs. 36.41%, 2.78-2.87 vs. 2.98 × 106/μl, and 10.30-10.70 vs. 10.88%). Supplementation of iron in CSM diets improved the PCV, RBC numbers, and Hb, and the values were comparable to the control. White blood cell numbers, mean corpuscular volume, mean corpuscular Hb (MCH), and MCH concentration values were comparable to the control. The erythrocyte osmotic fragility (EOF) was poor in birds fed diets containing up to 4% CSM BTAA or CSM BDAA without iron supplementation (32.02-32.57 vs. 28.77%). Supplementation of iron improved the EOF. The serum cholesterol level did not change with or without iron supplementation. Conclusion: This study suggested that feeding of CSM BTAA or BDAA up to 4% level voiding iron supplementation lowers the hematological parameters, whereas supplementation of iron did not alter serum protein fractions and cholesterol profile; however, it had lowered some hematological parameters, which was rectified by iron supplementation.
