Abstract

BackgroundThe present experiment was performed to assess the effects of different sources of milk on the growth performance, serum metabolism, immunity, and intestinal development of calves. Eighty-four Holstein male neonatal calves were assigned to one of the following four treatment groups: those that received bunk tank milk BTM, untreated waste milk UWM, pasteurized waste milk PWM, and acidified waste milk AWM for 21 d.

ResultsCalves in the BTM and AWM groups consumed more starter P < 0.05 than those in the UWM group. Average daily gain in the UWM group was the highest P < 0.05. Calves exhibited the highest P < 0.05 serum total protein, albumin, total cholesterol, high density lipoprotein, triglycerides, growth hormone, immunoglobulin Ig A and IgM concentrations in the UWM group, highest malondialdehyde and tumor necrosis factor-α in the PWM group P < 0.05, and highest glutathione peroxidase and IgG in the BTM group P < 0.05. The jejunum and ileum of the calves in all treatments presented a slight inflammatory response. The jejunal inflammation scores were higher P < 0.05 in the UWM and AWM groups than the BTM group; the ileal inflammation scores increased more P < 0.05 in the AWM group than the BTM group. Jejunal immunohistochemical scores IHS were higher P < 0.05 in the PWM and AWM groups than the BTM group. Compared to the other three groups, calves feeding on BTM had lower P < 0.05 ileal IHS. Jejunal interleukinIL-1β, IL-8, and IL-10 mRNA expression in the UWM group was the highest P < 0.05. Calves fed AWM increased P < 0.05 mRNA expression of IL-8 and toll like receptor 4 TLR-4 in the jejunum and IL-8, IL-1β, IL-6, IL-8, and IL-10 in the mesenteric lymph nodes.

ConclusionsOverall, bunk tank milk is the best choice for calf raising compared to waste milk. The efficiency of feeding pasteurized and acidified waste milk are comparable, and the acidification of waste milk is an acceptable labor-saving and diarrhea-preventing feed for young calves.
