BACKGROUND Holder pasteurization (milk held at 62.5°C for 30 minutes) is the standard treatment method for donor human milk. Although this method of pasteurization is able to inactivate most bacteria, it also inactivates important bioactive components. Therefore, the objective of this study was to investigate ultraviolet irradiation as an alternative treatment method for donor human milk. MET...

six red sokoto (rs) and west african dwarf (wad) does, raised intensively in livestock farm of michael okpara university were evaluated for milk yield and composition in a ten-week study. the animals in their first parity were fed cut-and-carry forages in a cafeteria arrangement between 07:00-08:00 h daily and also were allowed access to concentrate supplementation by 14:00 h. the forage consis...

Raw milk is a valuable food which its quality is important regarding both milk consumption itself and manufacturing of other dairy products. The aim of this study was to investigate the effect of different seasons on the variations of raw milk composition. To do so different samples of raw milk were taken during summer and winter from Qazvin province and their physicochemical properties includi...

the study was carried out for a period of 150 days on 120 holstein friesian crossbred dairy cows between mid to late lactation to quantify the influence of body condition score (bcs) on yield and composition of milk. total 12 dairy farms having same housing systems and holding at least 20 crossbred dairy cows per farm between mid to late lactation were selected for this study purposes. bcs of i...

The Madras Act has also standardized the value of proteins of the cow milk as nitrogen at 0.5 per cent and that of dirt in it at 5 per 100,000 by volume. It may be remembered here that the standards fixed in England by the Ministry of Agriculture and Fisheries by their Sale of Milk Regulation, 1901, are 3 per cent for milk and 8.5 per cent for milk solids other than milk fat. So the standard pr...

this study investigated the effect of season (wet and dry) on milk composition of the dromedary camel (camelus dromedarius). milk samples representing the wet and dry seasons were analyzed for total solids (ts), fat (f), solids-non-fat (snf), ash, crude protein (cp), nitrogen soluble at ph 4.6 (sn), mineral content (mc) and casein fraction (cnf). camel milk had higher (p<0.05) fat content in th...

The objective of the present study was to determine the effects of feeding pelletized broccoli byproducts (PBB) on milk yield and milk composition in dairy cows. In Trial 1, an in vitro gas test determined the optimal replacement level of PBB in a concentrate mixture in a mixed substrate with Chinese wild ryegrass hay (50:50, w/w) at levels of 0, 10%, 20%, 30%, or 40% (dry matter basis). When t...

The objective was to evaluate the effect of beta-lactoglobulin (beta-lg) polymorphism and seasonality on milk composition (fat, lactose, total solids, milk urea nitrogen, total protein, true protein, casein and somatic cell counts) of Holstein and Girolando cows. Milk and blood samples from 278 Holsteins cows and 156 Girolando cows were taken during two dry seasons and two rainy seasons, for mi...

An experiment was conducted with the objective of measuring the concentrations of total milk solids (TMS), CP, and 5′monophosphate nucleotides in sow colostrum and milk. Twelve multiparous sows (Landrace × Yorkshire × Duroc) were used. Litter size was standardized at 11 piglets for all sows at farrowing. Sows were fed an 18.45% CP corn–soybean meal-based diet throughout lactation. The experimen...

The objective of this study was to determine the effect of increased vitamin D fortification (250 IU/serving) of high-temperature, short-time (HTST)-processed 2% fat milk, UHT-processed 2% fat chocolate milk, and low-fat strawberry yogurt on the sensory characteristics and stability of vitamin D during processing and storage. Three replicates of HTST pasteurized 2% fat milk, UHT pasteurized 2% ...
