Growth performance and blood profile of West African Dwarf (WAD) goats fed varying levels of treated sweet orange peels

Abstract

Fifteen West African Dwarf grower bucks of about 6-8 months of age and average weights of 8.39 kg were used in a 70-day study to assess the intake and blood profile of West African Dwarf (WAD) goats fed diets containing graded levels of treated sweet orange peel meal (TSOPM), in a completely randomized design. Sweet orange peels were collected from sweet orange retailers within Makurdi, Benue State, Nigeria. The peels were packed into synthetic bags, compressed, and allowed to ferment for 12 h before sun-drying. The sun-dried peels were crushed into a meal and used to compound four treatments diets which consisted of 0, 60, and 80% TSOPM, designated diets A, B, and C respectively. Results showed that there were no significant differences (P > 0.05) among the treatments in all the performance parameters except in the total forage intake values in which treatment A (19.74 kg) was significantly lower (P < 0.05) than treatment B (21.77 kg) and treatment C (21.96 kg). But between treatment B and treatment C, there was no difference. Effect of treatments was also not apparent on the haematological indices measured, but the serum biochemical parameters showed significant difference (P < 0.05) among the treatments for total protein values. The total protein value for treatment C (8.02 g/dl) was significantly higher (P < 0.05) than treatments A (7.10 g/dl) and B (6.62 g/dl). The study showed that treated sweet orange peel meal can be used up to 80% level to replace maize offal in the diets of goats without adverse effects on the performance blood indices.

Effect of Interval of Feeding Roughage and Concentrate on the Haematological and Biochemical Parameters of Sokoto Red Buckling

“…The values of aspartate aminotransferase (AST) and alanine amino tranferase (ALT) obtained in this study was within the normal ranges of 124.00-143.33 iu/l and 35.33-46.00 iu/l, respectively (Sirois 1995). The AST values were higher than the values (21.02-43.78 iu/l) reported by Oloche et al (2019) for Kano brown goats fed Gmelina arborea leaves and supplemented with diets containing water soaked sweet orange (Citrus sinensis) peels, while the ALT values obtained in this study were also higher than the range of 10.10-12.98 iu/l also reported by Oloche et al (2019). Increased ALT values are a sign of liver disease, because it's a liver-specific hepatocellular enzyme that is used to assess liver damage (Mahgoub et al, 2008).…”

Hematological parameters of sheep and goats fed diets containing various amounts of water hyacinth (Eichhornia crassipes)

“…Furthermore, PCV, Hb, RBC, MCH, MCHC, and WBC ( 59 ) values were not affected by goat fed Mombasa or blue panic as a salt-tolerant alternative to replacing Alfalfa. PCV, Hb, RBC, MCV, MCH, and MCHC ( 60 ) values were not affected by West African Dwarf goats fed varying levels of treated sweet orange peels. The lack of significant effects observed in our study suggests that treatments and treatment-by-species interactions may not play a significant role in influencing hematological indices in the studied species.…”

Transforming orange waste with yeasts: bioprocess prospects

“…Nevertheless, this alternative can reduce the soil's pH, negatively affecting the process (Ruiz and Flotats, 2014). Because of this, the pomace and peel of this fruit, when used, are primarily intended only for dietary supplementation for cattle and goats (Oloche et al, 2019;Guzmán et al, 2020). Controversially, though, this biomass imparts a bitter taste to animal food, and stud-ies in the literature point to a potential generator of diseases in cattle (Bampidis and Robinson, 2006;de la Torre et al, 2019).…”
