“…The feeding of apple pomace to pregnant cows has previously been associated with the birth of calves with shortened long bones and enlarged joints (22 researcher (23 )mentioned that this problem was not alleviated by the addition of several trace minerals including 440 mg of Mn per day. This might be related to the increased Mn requirements under high calcium or potassium diets (14 ).…”

A severe congenital chondrodystrophy in Charolais oolves is described. Thirty-two calves were born on the same farm with shortened limbs and enlarged joints. Histologically, there was poor cartilage maturation with excessive amounts of rarefied cartilage matrix. There were degenerative changes in the chondrocytes and a severe reduction in the mucopolysaccharide content of all body hyaline cartilage. The cartilage matrix, when examined ultrastructurally, showed loose, disorganised fibres in a rarefied matrix, and extensive vacuolation of the chondrocytes. A low level of manganese was found in the liver of an affected calf. The pregnant cows were fed on apple pulp and corn silage, both of which are low in manganese.

“…For cows fed cottonseed meal, liver copper increased threefold during the 6-week period; whereas, for cows fed corn-urea, it increased by 1.6. Bovard et al (1977) have reported on the skeletal abnormalities of the calves born from cows fed NPN supplements and apple pomace. Rumsey et al (1977) have reported on the pesticide accumulation in the cows fed these diets.…”

Blood and ruminal samples were analyzed from gestating cows fed apple pomace or corn silage plus isonitrogenous and isocaloric quantities of cottonseed meal or nonprotein nitrogen containing supplements in four trials. Data were also obtained from steers fed similar diets during a metabolism trial. The supplementary sources of nitrogen supplied 50 to 70% of the total nitrogen in the diet. Feeding apple pomace, compared with feeding corn silage, resulted in greater (P~.01) molar percentages of acetic and valeric acids, lesser (P(.05) molar percentages of propionic, butyric, isobutyric and isovaleric acids and lowered (P(.01) ruminal pH. Ruminal ammonia concentrations were greatest when the urea-corn supplement was fed, next greatest with biuret-corn and lowest with cottonseed meal.Steers in a metabolism trial were fed apple pomace plus either corn-urea or cottonseed meal. Results indicated that the steers excreted less (P(.01) fecal nitrogen and more (P~.05) urinary nitrogen but had similar nitrogen retentions when the urea-corn supplement was fed than when cottonseed meal was fed. Cows and steers fed the urea supplement had lowered plasma concentrations of several of the essential amino acids. Blood mineral profiles in cows were similar regardless of the source of supplementary nitrogen. (

“…It serves as a useful energy source because of high content of soluble carbohydrate for ruminants . Studies conducted on AP (Rumsey, 1978;Bovard et al, 1977;Oltjen et al, 1977) showed that AP supplemented with natural proteins was comparable to protein enriched corn silage. In contrast, Elliott et al (1981) demonstrated that tomato pomace (TP) has the potential to be a good source of proteins, and its energy source may be limited due to the high fibre content.…”

The effect of ensiled mixed tomato and apple pomace on Holstein dairy cow

et al. 2010

This study was carried out to evaluate the effects of replacing alfalfa hay with ensiled mixed tomato and apple pomace (EMTAP) on ruminal fermentation, blood metabolites, chewing activity and apparent digestibility of diets. Six multiparous mid-lactating Holstein dairy cows were used in 3×3 Latin square design. The animals were fed with a control (0%EMTAP) and two different levels of EMTAP (15, 30%) containing diets. Results showed significant differences between treatments. The substitution of EMTAP in dairy cow’s diet was associated with a reduction of chewing activity, better DM and OM digestibility and higher blood metabolites concentration. Feeding EMTAP resulted in a significant higher concentration of acetic, propionic acids, and total volatile fatty acids in rumen, and lower rumen pH. It was concluded that, EMTAP might efficiently comprise up to 30% of the diets. The nutritive value of tomato and apple pomace could be improved when they are used together (50:50) in dairy cows diet
