Utilisation of Apple pomace as livetock feed: A review

Effect of feeding graded levels of apple pomace on growth performance, haemato-biochemical parameters and rumen metabolites in crossbred calves

“…These results were in concurrence with reported observations of Chandel et al (2015). The increased trend of hematological values in present study might be attributed to increased concentration of iron in apple pomace (Beigh et al 2015). However, the results of present study showed significant variation in total serum proteins between different experimental groups, which corroborated with observations of Abdollahzadeh and Abdulkarimi (2012).…”

A novel feedstuff: ensiling of cowpea (Vigna unguiculata L.) stover and apple (Malus domestica Borkh.) mixtures. Evaluation of the nutritive value, fermentation quality and aerobic stability

“…45 and 60 days) did not influence the chemical composition of the mixture and its IVOMD, indicating that silage was stable at 45 ensiling days. Previous studies have shown that silage from apple pulp and wheat straw may achieve stability after 30 ensiling days . Comparison of the pre‐ensiled mixture with the silage at silo opening indicated clear changes in the chemical composition as a result of the ensiling process.…”

“…Previous studies have shown that silage from apple pulp and wheat straw may achieve stability after 30 ensiling days. 17,18 Comparison of the pre-ensiled mixture with the silage at silo opening indicated clear changes in the chemical composition as a result of the ensiling process. The DM content of silages after 45 and 60 days of ensiling (209.4 and 187.8 g DM kg −1 respectively) was lower than that presented by the pre-ensiled mixture (242.6 g DM kg −1 ).…”

“…42 On the other hand, an increase in the fibre fraction and protein contents of the silage was detected, possibly as a result of the decrease in its WSC content. 18 Nevertheless, Beigh et al 17 suggested that an increase in silage protein content can also originate from the increase in silage microbial population. Although the ensiling altered the chemical composition of the silage, its IVOMD did not differ from that of the pre-ensiled mixture.…”

“…According to Wadhwa and Bakshi, out of the total world production, 30–40% of apples are damaged and are discarded owing to their low calibre, presence of stains and deformations, among others, and therefore not marketed, thus representing a total residue of 24–32 Mt. In northern Portugal, these losses correspond to 15–30% of the total production, representing 13 000–17 000 t. The utilization of apple pomace as livestock feed has been evaluated, mainly for ruminant diets owing to the high content of pectins and sugars, which are rapidly fermented in the rumen .
