Abstract A study was conducted to observe the effect of soybean and rice bran oil supplementation onnutrient utilization, lactation performance and ruminal fermentation in Surti goats. Twentyfour multiparous lactating Surti does were distributed into four homogenous groups for entirelactation of 150 days. Control group (CON) was offered a basal diet consisting of compoundconcentrate mixture, green jowar and pigeon pea straws without any oil supplementation,while other treatment groups were additionally supplemented with soybean oil @ 3% of DMI(SBO), rice bran oil @ 3% of DMI (RBO) and equi-propotional blend of soybean oil and ricebran oil @ 3.0 % of DMI (SRBO). DM, CP, NDF and ADF intake (g/d) and digestibility (%)remained statistically (p>0.05) similar amongst dietary treatments groups. EE intake (g/d)and digestibility (%) was significantly (p<0.01) improved in all three oils supplementedgroups as compared to control but values between oils supplemented groups remained at par(p>0.05). Nitrogen balance of experimental groups remained unaffected (p>0.05) and all theanimals were under positive nitrogen balance. Milk yield (kg/d), milk fat, SNF, protein,lactose, FCM and ECM yields (g/d) were significantly (p<0.05) increased in oilssupplemented groups as compared to control. Feed efficiency in terms of MY/DMI andFCM/DMI significantly (p<0.05) improved in SBO, RBO and SRBO as compared to CON.Soybean and rice bran oil supplementation either alone or in combination significantlyreduced (p<0.05) SCFA, MCFA, SFA with increased LCFA and PUFA in milk. However,values between oils supplemented groups remained at par (p>0.05). Oil supplementationincreased (p<0.001) oleic acid (C18:1 n-9) and linoleic acid (C18:2 n-6) in SBO, RBO andSRBO as compared to CON while, linolenic acid (C18:3 n-9) remained non significantamongst treatments. Lipid quality indices (LQI) like atherogenicity index, thrombogenicityindex and hypocholesterolaemic/hypercholesterolaemic (h/H) index were significantlyimproved in all the oils supplemented groups as compared to control. Rumen pH, totalnitrogen and its fractions (ammonia N, TCA precipitable N and soluble N) remained similar(p>0.05) amongst treatment except TVFA. Thus, supplementation of soybean oil and ricebran oil either alone or in combination in lactating goat can be effectively used to improveboth nutritional quantity and quality of milk.

The study was conducted on “Swiss Albino” mice fed with additional supplementation of soybean oil and rice bran oil to observe the effects on hematological (total erythrocyte count and hemoglobin concentration) and biochemical parameters (total serum cholesterol, triglycerides, high density lipoproteins and uric acid). A total of 30, 6-8 weeks old mice were randomly divided into 3 equal groups (n=10) as A, B and C. Group A was considered as control (fed only commercial ration), group B was supplemented with rice bran oil and group C treated with soybean oil respectively in addition to commercial ration for 60 days. At the end of feeding trial the mice were sacrificed for analysis of hematobiochemical parameters. The total erythrocyte count and hemoglobin concentration were increased significantly (P<0.05) in group B and C compared to control group A and the highest values was recorded in soybean oil group C. The total serum cholesterol, triglycerides, HDL and uric acid were increased significantly (P<0.05) in both rice bran oil and soybean oil group compared to control group. It is concluded that some hemato-biochemical parameters of blood in the mice are affected by rice bran and soybean oil enriched diet. Though, oils and fats are detrimental to health but to evaluate the effects of rice bran and soybean oil, further studies with more animals and some other parameters like liver function, kidney function may be conducted.

AbstractUse of antibiotics as feed additives has been reduced to avoid the hazard of drug residues, and consequently, the search for alternative natural additives has developed. Thus, the aim was to evaluate the influence of royal jelly (RJ) supplementation on milk composition, blood biochemical and antioxidant parameters of lactating ewes. Thirty-six Ossimi ewes were divided randomly into two groups (18 animals each). For a period of 4 weeks, the control group (CON) was fed a basal diet only, while the other group was fed the basal diet and supplemented with a single bolus of RJ (1000 mg/head). The RJ-supplemented ewes produced significantly higher milk protein, fat and total solids than the CON group. The RJ group had a significantly higher red blood cell count, haemoglobin content, haematocrit value and total leucocyte counts, but lower neutrophil to lymphocyte ratio when compared with the control treatment. The RJ group showed significantly higher concentrations of total antioxidant capacity, superoxide dismutase activity and glutathione in the serum compared with the control treatment. In conclusion, RJ supplements can improve the nutritive value of milk fat and the serum antioxidant activities in lactating ewes.

Alkyl Polyglycoside

This study evaluated the effects of alkyl polyglycoside (APG), which is a non-ionic surfactant, on lactation performance, nutrient digestibility and blood metabolites in dairy cows. Twenty dairy cows were randomly divided into four groups and fed a basal diet that included pelleted concentrate, distillers grains, and fresh limpograss. The four treatments included 0, 5.5, 11 and 22 mL APG per kg of pelleted concentrate on a dry matter basis; treatments were defined as APG0, APG5.5, APG11, and APG22, respectively. Dry matter intake was not affected by APG supplementation. There was an increase in milk yield (from 13.96 to 16.71 kg/day) and increases in milk fat (quadratic, p = 0.04), protein (quadratic, p = 0.10), and lactose concentrations (linear, p = 0.07) with increasing APG supplementation. In addition, APG supplementation increased (p ≤ 0.03) the milk fat, protein, solid non-fat, and total solid yields, while the lactose yield increased (linear, p = 0.01) as the APG level increased. Dietary APG supplementation had no effect on nutrient digestibility and blood metabolites. It was concluded that the addition of APG at doses up to 22 mL/kg of pelleted concentrate had positive effects on the milk composition in dairy cows.

Eucalyptus Oil

Abstract This study aimed to investigate the effects of naturally protected eucalyptus oil supplementation in a form of leaves (EUL) or mature seed capsules (EUS) compared to crude eucalyptus oil (EUO). The control group (G1) received the basal diet consisting of concentrate feed mixture, fresh berseem, rice straw, and corn silage. The G2, G3, and G4 animals were fed the basal diet with a supplement of 200 g/head/day of EUL or EUS or 4 mL EUO, respectively. Supplementation with EUL or EUS increased NH3-N, SCFA, and acetic acid concentrations in-vitro. The total count of bacterial, protozoa and cellulolytic bacteria increased (P < 0.05) with EUL and EUS supplementation. Methane production lowered (P < 0.05) with EUS, EUL, and EUO supplementation. Milk fat decreased (P < 0.05) with EUO supplementation, while an adverse trend was shown for lactose. No differences in feed conversion were found among EUS, EUL, and EUO. Total protein, albumin, and blood urea increased (P < 0.05) with supplementation of EUL or EUS compared to EUO. EUO supplementation yielded increased (P < 0.05) AST, ALT, glucose, and creatinine. Supplementation with EUL, EUS, or EUO decreased (P < 0.05) DM, OM, and CP digestibility. While digestibility of EE with supplementation by EUL, EUS, or EUO was higher (P < 0.05). Digestibility of NDF and ADF decreased (P < 0.05) with supplemental EUL, EUS, or EUO compared to the control diet. Feeding EUS increased the values of TDN and DCP compared to EUL, which was higher than EUO. Our results confirm that the naturally protected form of leaves or seeds mitigates the negative effects of directly supplementing crude eucalyptus oil.

Cholesterol Levels

The main goal of this experiment was to study the effect of milk fat depression, induced by supplementing diet with plant oils, on the bovine fat metabolism, with special interest in cholesterol levels. For this purpose 39 cows were divided in three groups and fed different rations: a control group (C) without any oil supplementation and two groups with soybean oil (SO) or rapeseed oil (RO) added to the partial mixed ration (PMR). A decrease in milk fat percentage was observed in both oil feedings with a higher decrease of −1·14 % with SO than RO with −0·98 % compared with the physiological (−0·15 %) decline in the C group. There was no significant change in protein and lactose yield. The daily milk cholesterol yield was lower in both oil rations than in control ration, while the blood cholesterol level showed an opposite variation. The milk fatty acid pattern showed a highly significant decrease of over 10 % in the amount of saturated fatty acids (SFA) in both oil feedings and a highly significant increase in mono (MUFA) and poly (PUFA) unsaturated fatty acids, conjugated linoleic acids (CLA) included. The results of this experiment suggest that the feeding of oil supplements has a high impact on milk fat composition and its significance for human health, by decreasing fats with a potentially negative effect (SFA and cholesterol) while simultaneously increasing others with positive (MUFA, PUFA, CLA).

We evaluated whether olive leaves (OLs) are effective as feed additives and supplements for ruminants and the potential methane reduction effects during in vitro fermentation. Two Hanwoo cows (460 ± 20 kg) equipped with cannula were fed Timothy hay and corn-based feed 3% of the body weight at a ratio of 6:4 (8:30 a.m. and 5:00 p.m.). Ruminal fluid from the cows was collected and mixed before morning feeding. In vitro batch fermentation was monitored after 12 and 24 h of incubation at 39 °C, and OLs were used as supplements to achieve the concentration of 5% in the basal diet. At 12 h of fermentation, methane production decreased in the 5% OLs group compared to that in the control group, but not at 24 h. The proportion of cellulose-degrading bacteria, Fibrobacter succinogenes, Ruminococcus albus, and Ruminococcus flavefaciens, tended to increase in the 5% OLs group at 12 h. The amount of ammonia produced was the same as the polymerase chain reaction result for Prevotella ruminicola. At 12 h, the proportion of Prevotella ruminicola was significantly higher in the 5% OLs group. OLs may be used incorporated with protein byproducts or other methane-reducing agents in animal feed.
