“…Results showed that in vivo DMD, OMD and DOMD of almond hull were approximately 10.1, 17.1 and 15.5% units greater than in vitro study, respectively. Dry matter digestibility of almond hull was calculated as 645.0 g kg -1 DM, which agrees with previous report (Alibes et al, 1983). However, DMD of almond hull in current study was greater than that observed by Aguilar et al (1984) ) was in agreement with others (Alibes et al, 1983;Aguilar et al, 1984;NRC, 2001).…”

“…Production of almonds and the by-product hull has been increasing rapidly in recent years. Various workers examined the chemical composition and nutritive value of almond hull and reported that hull as a feedstuff contained 2.1 to 8% crude protein (CP) (Fadel, 1999;Getachew et al, 2002), 1.69 to 2.9% ether extract (EE) (Reed and Brown, 1988;Getachew et al, 2004), 28 to 38.49% neutral detergent fiber (NDF) (Reed and Brown, 1988;Getachew et al, 2004), 48.7 to 57.8% non fibrous carbohydrate (NFC) (Reed and Brown, 1988), 59.6 to 66.7% in vivo dry matter digestibility (DMD) (Alibes et al, 1983;Aguilar et al, 1984) and 1.85 to 2.87 Mcal/kg metabolizable energy (Alibes et al, 1983;Fadel, 1999). The objective of this study was to evaluate the chemical composition and digestibility of almond hull as a feed for sheep.…”

A study was conducted to determine the chemical composition and digestibility of almond hull using invitro, sacco and vivo methods. Chemical compositions of almond hull and alfalfa hay were determined. The crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of almond hull were lower than those of alfalfa hay but the non fibrous carbohydrate (NFC) was more than that of alfalfa hay (3.5 times) (P < 0.01). The dry matter disappearance of almond hull for all incubation times using in sacco method was greater than that of alfalfa hay (P < 0.01). To measure in vivo digestibility, four mature Moghani sheep of live weight (39 ± 3 kg mean±SD) were used in a 2 × 2 change over design. Diets consisted of a basal diet (alfalfa hay) and a mixed diet (alfalfa hay 70% + almond hull 30%). Invitro and vivo dry matter digestibilities of almond hull were 585.8 and 645.0 gkg -1 , respectively. There was no difference between in vivo dry and organic matter digestibility of alfalfa hay and mixed diet but were significantly affected in the case of CP and NDF (P < 0.01). In general, almond hull had low CP but greater NFC content as well as greater digestibility in sheep.

The hazelnut skin is waste biomass rich in bioactive compounds that may affect lipid rumen metabolism, ruminant performance, and products’ quality. Therefore, we investigated the effect of dietary hazelnut skin on milk production and composition and on rumen fatty acids in ewes. During 28 days, 20 Comisana lactating ewes received alfalfa hay ad libitum plus 800 g/head/day of pelleted concentrate containing 36% dried beet pulp (CTRL group; n = 10) or 36% hazelnut skin (HS group; n = 10). The protein percentage was lower in HS milk. Milk fatty acids (FA) partially reflected those of rumen content. Total saturated FA (SFA), odd and branched-chain FA, and n-3 polyunsaturated FA (PUFA) were greater in CTRL milk. Total monounsaturated FA (MUFA) and 18:1 trans were greater in HS milk; moreover, HS milk showed a double percentage of oleic acid than the CTRL group. Individual SFA were greater in CTRL milk except for 18:0. Differing from the rumen content, total PUFA, n-6 PUFA, and 18:2 n-6 were comparable between groups. Vaccenic and rumenic acid were greater in HS milk. To conclude, dietary HS slightly reduced milk protein percentage but improved atherogenic index and healthy FA in milk. The content of the somatic cells suggested a healthier udder in the HS group.

“…Almond hulls (AHs) were not considered as a valued feedstuff before 1948 and were used as a fuel material or were destroyed (6). The nutritional value of AHs has been determined in sheep (2,7,8), dairy cow (4), goat (9), horse (10), and pig (11), in which AHs were shown to have an energy value of 65.00% to 90.00% of barley and to be equivalent to early and mid-bloom alfalfa hay, and they were introduced as a safe and palatable feedstuff. In a study by Getachew et al (12) about the relationships between chemical compositions of several ruminant feeds, nonfibrous carbohydrate (NFC) content of AHs (48.70%) was higher than that of alfalfa (ALF) (26.80%) and almost the same as that of sugar beet pulp (SBP) (43.80%).…”

IntroductionWith the dramatic rise in prices of corn, alfalfa, and other traditional feed ingredients, nutritionists are getting more creative and turning to nontraditional products (1). Agricultural residues are byproducts of cereals, sugarcane, oilseeds, oil plants, vegetables, and fruits obtained during harvesting and processing of a commodity from which human food is derived (2). These byproducts have been of interest to many researchers since the 1970s because of the desire to understand and reduce environmental waste in most countries (2,3). Using such byproducts for animal feed is a means of recycling something that otherwise, if accumulated, might cause environmental pollution (3). The almond hull is obtained by drying that portion of the almond fruit that surrounds the wooden shell and includes the exocarp and mesocarp of the fruit and can be utilized in different ways. The proportion of hull is 50.00% of the total weight of the almond (2,4). Almond and almond hull production has continuously increased over the past decades. In 2008, approximately 2,110,000 t of almonds were commercially produced in the world (5), resulting in the availability of equal tons of hulls (3). Almond hulls (AHs) were not considered as a valued feedstuff before 1948 and were used as a fuel material or were destroyed (6). The nutritional value of AHs has been determined in sheep (2,7,8), dairy cow (4), goat (9), horse (10), and pig (11), in which AHs were shown to have an energy value of 65.00% to 90.00% of barley and to be equivalent to early and mid-bloom alfalfa hay, and they were introduced as a safe and palatable feedstuff. In a study by Getachew et al. (12) about the relationships between chemical compositions of several ruminant feeds, nonfibrous carbohydrate (NFC) content of AHs (48.70%) was higher than that of alfalfa (ALF) (26.80%) and almost the same as that of sugar beet pulp (SBP) (43.80%). Crude protein (CP) contents of AHs and SBP were almost the same (8.00% and 9.00% for AHs and SBP, respectively), but were lower than that of ALF (26.00%), while neutral detergent fiber (NDF) contents of AHs, SBP, and ALF were also almost the same (33.60%, 31.80%, and 33.80% for AHs, SBP, and ALF, respectively).The nutritive value of a ruminant feed is determined by the concentrations of its chemical components, as well as their digestibility. Determining the digestibility of feeds in live animals (in vivo) is laborious and expensive, requires large quantities of feed, and is time-consuming. The in situ nylon bag technique represents a less expensive and more
