“…It has been reported that the high chlorophyll content of avocado lipids can act as a proxidant by stimulating photo-oxidation [42]. In contrast, to our results, Eliyahu et al [12] reported that Assaf lambs weighting 50 ± 1.5 kg consumed daily 1.0 kg DM of a total mixed diet containing 49.6% fresh avocado pulp. The high avocado intake observed in their study would indicate a high palatability of fresh avocado that has not underwent lipid oxidation, as may have happened in our study.…”

“…Average values of individual daily intake of feeds and nutrients in dairy goats fed the experimental diets. Eliyahu et al [12] observed that avocado pulp stored outdoors (25 • C of average temperature) in containers covered with paper sheets was rapidly contaminated by mold and yeast within the first 3 days of storage despite of its low initial pH (4.52). These authors observed that the pH of avocado pulp was increased from 4.52 to 8.30 over the first 7 days of storage, whereas the in vitro DM digestibility the water soluble carbohydrates content was reduced from 30% to 22% and from 15.3 to 1.62 g/kg DM, respectively.…”

“…In broiler chickens, van Ryssen et al [10] observed that the inclusion of 7.3% to 29.3% dried avocado meal in the diet reduced the feed intake and the growth of the animals. Whereas some data are available on the composition, rumen in situ degradability and digestibility of avocado meal and pulp for ruminants [11,12], to our best knowledge, no information exists on the effect of feeding avocado wastes to dairy ruminants. Our hypothesis was that a mixture of avocado pulp and peels could partially replace conventional ingredients in a concentrate for dairy goats, decreasing feeding costs and improving milk yield and/or the FA profile of milk.…”

Twelve Murciano-Granadina dairy goats were divided into two homogeneous groups, which were fed either a control diet composed of 40% alfalfa hay and 60% concentrate or a diet based on 40% alfalfa hay, 40% concentrate and 20% multinutrient blocks, including 14.8% avocado pulp and peels (APP). Total dry matter (DM) intake was similar (p = 0.709) for both diets, but APP-fed goats had lower (p = 0.024) concentrate intake and tended (p = 0.063) to have lower fat intake compared with those fed the control diet. The average intake of blocks was low (66.4 g DM/d), which was attributed to avocado lipids oxidation and rancidity. Neither milk yield (p = 0,921) nor the efficiency of energy and nitrogen use were affected (p = 0.909 and 0. 840, respectively) by the diet, but milk fat tended to be greater (p = 0.057) in the APP-fed goats compared with the animals fed the control diet. Other milk components were similar (p ≥ 0.110) for both diets, and only subtle changes in the milk fatty acid profile were observed. In summary, the intake of blocks containing avocado wastes by dairy goats was low probably due to avocado lipids oxidation causing off-flavors and reduced palatability.

“…A previous study examined direct ensiling in glass silos of fresh PP solely or in a mixture with various drier feeds. Results showed that without addition of drier feeds, high fermentation losses occurred (about 20% of DM) accompanied with reduction of in vivo DM digestibility of the ensiled PP in sheep (Eliyahu et al 2015b). The best combination used for successful ensiling of PP in the glass silos was a mixture of fresh PP with soy hulls and corn silage at DM proportions of: 40:35:25, respectively.…”

Based on a previous ensiling study in glass silos of various pomegranate pulp (PP) mixtures, fresh pomegranate pulp (PP) was mixed with drier feeds including soy hulls and corn silage (40:35:25 on DM basis) and ensiled in 32 pressed bales (700 kg each) wrapped with stretch polyethylene film. This ensiled pomegranate pulp mixture (PPM) was included in lactating cow total mixed ration (TMR) at a level of 20% of DM (PPM-TMR). Performance and digestion experiment was conducted with two groups of 21 milking cows each, fed individually one of the two TMR: 1. Control TMR without ensiled PPM; 2. Experimental TMR which contained 20% ensiled PPM, including 8% PP as corn grain replacer. Voluntary DM intake of cows fed the control TMR was 5.04% higher than that of the PPM cows. In vivo digestibility of DM, OM, NDF, CP and fat were significantly higher in the control cows compared with the PPM group, but methane production in the rumen fluid was 25% lower in the PPM cows. A slightly higher milk yield (by 2.2%) observed in the control cows; however, milk fat content was 5.9% higher in the PPM cows. This was reflected in similar yield of energy corrected milk (ECM) and 3.97% increase in production efficiency (ECM/DM intake) of the PPM cows compared with the control ones. Welfare of the cows, as assessed by length of daily recumbence time, was in the normal range for both groups. Body weight gain was also similar in both groups. Data suggest that the level of 8% PP in the PPM-TMR used in this study was probably too high for lactating cows and should be lowered to 4% in order to achieve better performance.

“…The use of alternative feeds in diets can improve the quantity and quality of ruminant feed by including regional byproducts purchased at low cost to replace traditional ingredients, such as corn and soybean meal, among other ingredients of high commercial value. Therefore, many studies have been conducted in recent years to assess whether these byproducts can be used without negatively affecting animal production (LUZ et al, 2017;ELIYAHU et al, 2015;ABUBAKRET al., 2013;HABIB et al, 2013).…”

This study evaluated the chemical composition and ruminal degradability of dry matter (DM), neutral detergent fiber corrected for ash and protein (NDFap) and crude protein (CP) in byproducts of African oil palm (palm cake, kernel or fiber), macaúba (pulp cake and kernel cake), acai (acai fruit), babassu (kernel cake) and pineapple (peel, crown and bagasse silage). Nineteen rumen-fistulated sheep were kept in individual stalls, receiving a daily diet composed of elephant grass silage and corn and soybean concentrate. After preparation in nylon bags, the byproduct samples were incubated for 0, 3, 6, 12, 16, 18, 24, 48, 72, 96, 120 and 144 hours, with three replicates of each ingredient per incubation time. The divergence between the protein nutritional value and energy nutritional value, based on discriminatory variables between groups, was estimated by cluster analysis. The effective degradability of DM, NDFap and CP for the different byproducts was, respectively, 35.9, 26.9 and 59.0% for palm cake; 48.3, 34.3 and 76.4% for palm kernel; 21.1, 6.6 and 50.3% for palm fiber; 34.3, 15.0 and 52.8% for macaúba pulp cake; 58.1; 63.0 and 51.6% for macaúba kernel cake; 49.7, 49.6 and 41.8% for babassu cake; 53.4, 40.5 and 79.8% for pineapple bagasse silage; and 21.3, 17.0 and 38.9% for acai fruit. Based on their NDFap and CP characteristics, the feeds were clustered in up to four different groups.
