“…Therefore, these nutrients can be obtained from acid whey because this by-product is a rich source of soluble sugars (specifically lactose), proteins, minerals, and vitamins, besides a variable amount of lactic acid (VALDUGA et al, 2006) and LAB (SANTOS et al, 2006). In other words, acid whey is an additional source of substrate for LAB into the silo (SCHINGOETHE, 1976), as observed in the present study through increases in the ash, CP (mainly when associated to urea), and EE contents. These results explain why the bakery by-product silages hydrated with acid whey exhibited higher lactic acid concentrations in general.…”

SUMMARY The objective of this study was to investigate the characteristics of silages prepared with a dry bakery by-product hydrated with acid whey or water associated or not at urea. The trial was a 3 (hydration at three moisture levels: 250, 300, and 350 mL kg−1 of by-product) × 3 (three application rates of urea: 0, 5, and 10 g kg−1 of by-product) × 2 (liquid used at hydration: acid whey or water) factorial arrangement. Mini-silos were used as experimental silos and remained closed for 30 days. Overall, silages hydrated with acid whey had higher (P<0.01) production of lactic (19.6 vs. 18.5 g kg−1 of dry matter [DM]), acetic (2.5 vs. 1.8 g kg−1 of DM) and propionic acid (8.0 vs. 5.4 g kg−1 of DM), and lower (P<0.05) fungi counts (5.35 and 5.01 cfu g−1 of fresh silage) compared to silages hydrated with water. Increased hydration led to the higher production of total acids (P<0.01), decreasing silage pH; but increased hydration reduced DM recovery (P<0.01). Silages hydrated with water and acid whey at 250 mL kg−1 and combined at 5 and 10 g kg−1 of urea exhibited higher DM recovery (P<0.05). Silages of a dry bakery by-product hydrated with acid whey had a better fermentation pattern and could represent a practical strategy to avoid discarding both by-products into environment.

“…The general performance of the calves during the trial was good, although rate of gain of those fed chopped hay alone was below average (Otterby and Linn 1981). The onset of bloat symptoms during the 6th week of the trial for calves fed EWC in combination with the grain-based starter supported the earlier observation of Lvnch and McDonough (1919), Schingoethe (1976) and Fisher (1983). However, the fact that the replacement of the grain with chopped hay alleviated the bloat problem and that no bloat was observed for those calves fed chopped hay and EWC indicated that EWC could be safely fed in conjunction with a small amount of hay.…”

“…Retention of sodium and potassium was relatively high, particularly when EWC was fed ( (Lynch and McDonough 1979;Fisher 1983;Schingoethe 1976) that whey, in a partially dewatered form, can be used efficiently by ruminant animals for at least a 2-mo feeding period.…”

FIsnen, L. J. aNoBucxr-ev,W. T. 1985. Effectof feedingaconcentratedwheycanola meal mixture as the major component of starter rations for calves. Can. J. Anim. Thirty-two male Holstein calves were subdivided into four groups at 35 days of age and used to evaluate the feeding of an evaporated whey-canola meal f'eedstuff (EWC) fed in combination with either a grain-based starter ration or chopped hay. Over a feeding period of 7 wk, dry matter intake of EWC increased to 84 and 90Va of total dry matter intake for the grain-based and hay-based starter rations, respectively. Rumen fluid butyrate and valerate levels increased to 40Ea and l5%a, respectively, of total volatile fatty acids produced. Plasma urea levels were lower and phosphorus, potassium and copper levels were higher when EWC was fed. The digestibility of EWC-based diets was higher than either grain or hay diets without EWC. Nitrogen, calcium, sodium and potassium balances were substantially increased by the EWC-based diet. Bloat was a problem when the EWC was fed in conjunction with a grain-based starter ration. This problem was prevented by feeding small amounts of chopped hay. It was concluded from the results of this study that EWC could be fed in combination with chopped hay at up to 9OVa of the total dry matter intake of young calves without causing acidosis or digestive upsets. The influence of whey on the utilization of other nutrients in the ration may be considerably different at the higher levels of intake which can be achieved with the evaporated whey-canola meal product (Fisher 1983

“…However~in the case ofsmall cheese plants, Fevrier and Bourdin (1977) showed that this use remained of interest. Similarly, it is possible to incorporate into cattle and sheep feed rations up to 30% of dry matter as liquid whey (Schingoethe, 1976). With regard to human food uses, the production of beverages from cheese whey has been attempted in several countries.…”
