“…No effect of feed intake with C. vulgaris and Cu supplementation is consistent with previous reports for the mixture (Kholif et al, 2020) or C. vulgaris alone (Lamminen et al, 2019). Kholif et al (2020) reported that feeding the same mixture of additives at 10 g of C.…”

“…The use of microalgae as a feeds or feed supplement for ruminants gained increasing interests (Marrez et al, 2017;Gomaa et al, 2018;Kholif et al, 2020). Supplementing diets of animals with microalgae, at small amounts, showed positive effects on animal physiology, health status and productivity (Póti et al, 2015;Kholif et al, 2017dKholif et al, , 2020. Chlorella vulgaris microalgae supplementation to dairy animals enhanced daily milk production and altered milk nutritive value by reducing saturated fatty acid (SFA) and increasing unsaturated fatty acids (UFA) concentrations (Kholif et al, 2017d), due to its content of crude protein (CP), amino acids, UFA, minerals and vitamins (Kholif et al, 2017b).…”

“…The inclusion of copper (Cu) in diets of animals is essential for many enzymes and synthesis of connective tissues and transport of iron and formation of haemoglobin (NRC, 2007). Increasing the concentration of Cu in diets of animals showed some positive effects on the animal performance (Kholif et al, 2020). Moreover, Roshanzamir et al (2020) observed that supplementing lactating cows with trace minerals such as Cu had positive effects on dry matter (DM) intake and digestibility, lactational performance, somatic cell counts and milk total antioxidant capacity.…”

Thirty-two lactating Boer goats (35.2 ± 1.4 kg body weight) were grouped into control and three treatment groups in completely randomised design. In treatment groups, supplementation was done as a mixture of 5 g Chlorella vulgaris + 4.5 mg of supplemental Cu/kg diet from CuSO4 (Alg5 treatment), 10 g C. vulgaris + 9 mg of supplemental Cu/kg diet (Alg10 treatment), or a mixture of 15 g C. vulgaris + 13.5 mg of supplemental Cu/kg diet (Alg15 treatment). Treatments did not affect feed intake; however, Alg10 treatment increased (P<0.001) nutrient digestibility. Treatments did not affect ruminal pH, ammonia-N, butyrate; however, the Alg10 treatment increased (P<0.01) ruminal total volatile fatty acids, propionate and acetate concentrations. Without affecting other blood measurements, the Alg10 treatment quadratically increased (P<0.001) serum glucose and Cu. The Alg10 treatments increased (P<0.001) daily milk production and the concentration of fat, and enhanced milk (feed) efficiency. The Alg10 treatment decreased (P<0.05) milk saturated fatty acids and the atherogenic index, and increased the proportions of total conjugated linoleic acids, C18:1n9t, odd fatty acids and total unsaturated fatty acids compared with the control treatment. Present study concluded that inclusion of a mixture of 10 g C. vulgaris + 9 mg Cu/kg diet in the diet of lactating Boer goats enhanced nutrient digestibility, ruminal fermentation, milk production, feed efficiency as well as milk nutritive value. Increasing the dose of the mixture to 15 g C. vulgaris + 13.5 mg Cu/kg diet is not recommended in the diet of lactating Boer goats.
