The treatments consisted of ad libitum feeding of tef (Eragrostis tef) straw plus 172 g dry matter (DM) of cactus (Opuntia ficus-indica) pear (T1, control) and supplementation with 145 g DM cotton seed cake (CSC) (T2), 195 g DM noug seed cake (NSC) (T3) or 149 g DM peanut cake (PNC) (T4) per head per day.
The Langmuir isotherm model clearly explains the copper (II) adsorption on the cotton seed cake.
Finally, the characteristics of the cotton seed cake were analyzed using FTIR, XPS and SEM with EDS.
In the first stage, through simplex centroid design maximum L-asparaginase activity was observed using a ternary mixture of cotton seed cake (2/3), wheat bran (1/6), and red gram husk (1/6).
The factorial design involved two breeds, two infection treatments (infected vs non-infected) and three dietary protein treatments (hay and wheat bran (basal diet), hay plus molasses urea block (MUB), hay plus cotton seed cake (CSC)).
The factorial experimental design involved two breeds, two infection treatments (infected vs. noninfected) and three nutrition treatments [hay plus wheat bran (basal diet), hay plus molasses urea block (MUB), hay plus cotton seed cake (CSC)].
For in situ degradability trials, soybean meal (SBM), corn gluten meal (CGM), cotton seed cake (CSC), wheat bran (WB) and corn gluten feed (CGF) were weighed into Dacron bags and incubated in the rumen of three cannulated Chios ewes.
In this study, copper (II) ion reduction was investigated using a four-factor three-level Box Behnken statistical experimental design (BBD) under different adsorption conditions, such as initial concentration, cotton seed cake dose, pH and temperature.
Optimum conditions for maximizing the copper (II) reduction were determined using Derringer's desired function methodology and were found to be an initial concentration of 300 mg/l, cotton seed cake dose of 1 g/l, pH of 7, and a temperature of 50 °C.
