5 Abstract Bovine colostrum (the first milk produced by cows during the initial days after giving birth) is the first milk secreted by cows after parturition (the action of giving birth to young)and has high levels of protein, immunoglobulins, (known as antibodies, in your blood,antibodies are substances made by the body's immune system in response to bacteria, viruses, fungus, animal dander, or cancer cells) and various growth factors(a substance, such as a vitamin or hormone, which is required for the stimulation of growth in living cells). We determined the effects of 8 weeks of bovine colostrum supplementation versus whey (is the liquid remaining after milk has been curdled and strained. It is a byproduct of the manufacture of cheese or casein and has several commercial uses) protein during resistance training in older adults. Males (N = 15, 59.1 ± 5.4 y) and females (N = 25, 59.0 ± 6.7 y) randomly received (double-blind) 60 g/d of colostrum or whey protein complex (containing 38 g protein) while participating in a resistance training program (12 exercises, 3 sets of 8-12 reps, 3 days/ week). Strength (bench press and leg press 1-RM), body composition (by dual energy x-ray absorptiometry(measurement of the amount of radiation absorbed (as by living tissue) especially to determine density)), muscle thickness of the biceps and quadriceps (by ultrasound), cognitive (concerned with the act or process of knowing, perceiving, etc)function (by questionnaire), plasma insulin(a hormone produced in the pancreas by the islets of Langerhans, which regulates the amount of glucose in the blood)-like growth factor-1 (IGF-1) and C-reactive protein (CRP, as a marker of inflammation), and urinary N-telopeptides (Ntx, a marker of bone resorption) were determined before and after the intervention. Participants on colostrum increased leg press strength (24 ± 29 kg; p < .01) to a greater extent than participants on whey protein (8 ± 16 kg) and had a greater reduction in Ntx compared with participants on whey protein (-15 ± 40% vs. 10 ± 42%; p < .05). Bench press strength, muscle thickness, lean tissue mass, bone mineral content, and cognitive scores increased over time (p < .05) with no difference between groups. There were no changes in IGF-1 or CRP. Colostrum supplementation during resistance training was beneficial for increasing leg press strength and reducing bone resorption in older adults. Both colostrum and whey protein groups improved upper body strength, muscle thickness, lean tissue mass, and cognitive function.

6 Summary Colostrum has high levels of protein, immunoglobulins, and various growth factors and due to this it  improves cognitive function.
