“…This detoxification is due to the ability of LY to extract abundant extracellular enzymes, such as tannase, which hydrolyzes tannins into glucose and gallic acid or ellagic acid (Hawashi et al 2019 ). In addition, this feed additive significantly decreased the excessive EE compounds of alperujo that reduce the attachment of the rumen microbiota to carbohydrates in the rumen (Joy et al 2021 ). A comparable effect was found with gum seed kernels fermented with LY (Gunun et al 2022 ).…”

Extraction of olive oil through a two-stage centrifugation process produces a large amount of phytotoxic waste known as alperujo. This research was performed to bioconvert alperujo into enriched ruminant feed by pretreatment with exogenous fibrolytic enzymes (EFE) or/and live yeasts (LY). These additives were used in a completely randomized design with 3 EFE doses (0, 4, and 8 µl/g dry matter) and 3 LY doses (0, 4, and 8 mg/g dry matter) in a 3 × 3 factorial arrangement. Fermented alperujo with both EFE doses converted some of their hemicellulose and cellulose to simple sugars and increased bacterial abundance in the rumen. As a result, it shortens the lag time of rumen fermentation, increases the rate and amount of rumen fermentation, and improves digestibility. This improvement provides additional energy that can be used by ruminants to produce milk and by rumen microbiota to produce short-chain fatty acids. Fermented alperujo with a high dose of LY decreased their antinutritional compounds and reduced their high content of lipid. In the rumen, this waste became rapidly fermentable, and rumen bacteria became more abundance. Fermented alperujo with a high dose of LY + EFE accelerated rumen fermentation and improved rumen digestibility, energy available for milk production, and short-chain fatty acids compared to the use of LY or EFE alone. This synergistic interaction between these two additives increased protozoa abundance in rumen and the ability of rumen microbiota to bioconvert ammonia–nitrogen to microbial protein. Ultimately, fermentation alperujo with EFE + LY is a good strategy with minimum investment for a social sustainable economy and environment.

“…In some experiments, supplemental fats reduce DMI (Haddad & Younis, 2004;Mossad & Sayed, 2010), whereas in other studies, supplemental fat increased DMI (Manso et al, 2009). It has been argued that the effects of supplemental fat on cattle DMI are affected by type of fat, level of supplementation, and dietary composition and energy density (Hess et al, 2008;Joy et al, 2021). SEM = standard error of the mean; NE= net energy; DMI=dry matter intake; ADG=average daily gain a Control=without supplemental fat; TL = 4% tallow; YG = 4% supplemental yellow grease, and RTG = 4% grease trap waste.…”

The objective of this experiment was to compare the effects of dietary supplementation with cooking grease recovered from rinse-trap water lines (rinse-trap grease; RTG) versus conventional supplemental fats (tallow; TL, and yellow grease; YG) on 84-d growth performance, dietary energy, and carcass traits of feedlot lambs. Forty-eight Pelibuey × Katahdin lambs (27.7 ± 3.4 kg) were assigned in a randomized complete block design to evaluate: 1) basal diet without supplemental fat (Control); 2) 4% TL; 3) 4% YG, and 4) 4% RTG. Supplemental fats replaced maize in the control diet. Rinse-trap grease contained greater moisture (16.5 vs 0.92%) and impurities (3.6 vs 0.56%), and less total fatty acid (64.90 vs 89.60%) than that of conventional fats (TL and YG). Daily weight gain and gain efficiency were similar for control and RTG supplemental lambs, whereas ADG and gain efficiency were greater for lambs fed conventional fats than control or RTG-supplemented lambs. Both dietary net energy (NE) as well as ratio of observed-to-expected dietary NE were 4% greater for lambs supplemented with conventional fats vs RTG. Supplemental fat increased fat deposition but did not affect any other carcass measures or non-fat visceral mass. Estimated NE value for RTG was 57% of the average NE value (6.11 Mcal/kg) of tested conventional fats. Supplementation with RTG does not affect diet acceptability, and accordingly, is a suitable energy source for feedlot lambs. However, due to its lower total fatty acid content, its energy value is much lower than conventional supplemental fats.

“…It is lower than fat contents in rice bran (EE=22 g/100 g DM) (Rafe et al 2007 . This energy compound can block the attachment of ruminal microbiota to carbohydrate, reducing their digestion and the proliferation of ruminal microbiota (Joy et al 2021). Almonds shell and hull have a low-fat content 0.6 and 1 g/100 g DM respectively.…”

Almond’s by-product is available in large quantities all over the world. However, little information is available about their feed value. The aim of this research was to determine their nutritional value and investigate the effect of pre-treating with exogenous fibrolytic enzymes (EFE) at 0, 1, 2, and 4 µL/ g DM.The result showed that the almond shell is a fibrous by-product with low energy value. The pre-treatment with high doses of EFE hydrolyses part of their cellulose and hemicellulose, improved their fermentation, digestibility and energy value. In addition, it improved protein produced by the ruminal microbiota and volatile fatty acids. This improvement is coupled with the reduction of methane emission. Almond teguments are rich in fibre and have high energy value due to their high fat content. A high content of condensed tannins has been detected in this by-product. The pre-treatments with EFE did not modify their fibre composition and nutritional value. Almond hulls have a high energy value due to their high non-fiber-carbohydrates content. It has moderate fibre compounds and high condensed tannins. The pre-treatment with EFE has no effect on their fibre composition. However, at the low dose, it improves their fermentation, digestion and protein produced by ruminal microbes and at the high dose it has an unharmful effect.This study can encourage farmers to use almond by-product as an alternative feed for ruminants. EFE is good strategy to improve nutritional value of almond by-product, reduce energy loss and protect the environment against global warming
