in a 3×3 latin square design, 9 ok and multipaous lactating holstein cows averaging 76 ± 12 days in milk and 580±48 kg of body weight were assigned to three dietary treatments in 3 periods of 21 days. dietary treatments were 1) the control diet (without dried or ensiled tomato pulp), 2) diet with 8% dried tomato pulp (dm basis) and 3) diet with 8% ensiled tomato pulp silage (dm basis). tomato p...

In order to improve the gut microbiome of calves, probiotic bacteria can be fed as active livingcells (fermented milk), or as live but inactive (freeze-dried) cultures. Ten bifidobacterial strains with suitable probiotic properties (as determined in our previous study) were tested for survival during the freeze-drying process, and screened for their ability to ferment cow’s milk. The viability ...

Sixteen Holstein cows in midlactation were used in a 4 x 4 Latin square design to determine the effect of replacing alfalfa NDF with NDF from whole, linted cottonseed or dried distillers grains. Low and high fiber control diets (13 and 19% of dietary DM from alfalfa haylage NDF, respectively) were compared with diets designed to contain 13% of DM from alfalfa haylage NDF plus 6% of DM from eith...

Pregnant cows were successfully hyperimmunized with all four human rotavirus serotypes, resulting in a 100-fold increase in neutralizing milk antibody titers over those of controls. Milk antibodies were isolated batchwise from 1,000 kg of pooled milk for the first 10 lactation days, yielding 10 kg of freeze-dried milk immunoglobulin concentrate consisting of 50% bovine milk immunoglobulins. Mil...

Imports of milk protein concentrates (MPCs) are increasingly entering the United States with minimal trade restrictions. MPC is a general reference to a dried protein product derived from milk using a technology known as “ultra filtration.” Two questions are addressed in this article. First, did the combination of relaxed import restrictions, low world prices for protein, and relatively high do...

Peptonized milk, a t rypt ic digest of skim milk, proved unacceptable as a protein source for artificially reared piglets. When this product was substi tuted for dried skim milk, rate and efficiency of gain were sharply decreased and incidence and severity of diarrhea markedly increased. Rectal temperature was decreased. The difference in nutritiona~ adequacy of the diets, measured by a chick g...

characteristic of the udder, milk traits and their relationship were investigated in 32 awassi ewes raised in a commercial flock. commencing one month after lambing milk yield was recorded at monthly intervals until the ewes were dried. also, the udder traits were measured, including udder width, udder circumference, udder length, distance between teats and length and diameter of both teats. re...

In this research, an industrial spray dryer was used and the effects of atomizer speed on the physicochemical properties of milk powder, the textural and sensory characteristics of white cheese made from this milk powder were evaluated. For this purpose, whole milk was converted into powder by using three different speeds (10,000, 11,000, and 12,000 rpm). The results showed that by increasing a...
