This study was conducted to investigate the effect of olive pomace in three levels of OP0, OP7.5 and OP15% on milk and yogurt composition and milk fatty acid pro le of dairy buffalo. Milk fat and SNF (solids not fat) increased in olive cake treatments (p < 0.05) but milk production, protein, and pH were not different (p > 0.05). The acidity, microbial load, Staphylococci, and SNF of yogurt produced from buffalo's milk did not in uence by treatments (p > 0.05). Yogurt fat decreased (p < 0.05) in OP7.5 and increased (p < 0.05) in OP15 buffalos. Protein concentration in yogurt dropped by olive pomace diets, and coliforms were the highest for OP15 olive pomace (p < 0.05). The concentration of short and medium chains fatty acids (C4:0, C8:0, C10:0, C12:0), linolenic acid, and conjugated fatty acids (CLA isomers) of buffalo's milk in OP15 is more than other treatments (p < 0.05). The replacement of olive pomace with wheat our increased milk production of dairy buffaloes. The concentration of short and medium-chain fatty acids and un-saturated and conjugated fatty acids increased in OP15 buffalos. Furthermore, a lower saturated/unsaturated ratio and atherogenic index suggest an improvement in nutritional characteristics of milk buffaloes. Therefore, it's recommended in the diet of dairy buffaloes.

Lactoferrin is found in mammalian milk but the camel milk has greater quantity of lactoferrinin compared with other livestock species. Lactoferrin strengthens the immune system by protecting the host cells against bacterial and viral infections and inflammations. Activation, proliferation and regulation of the phagocytic action of immune cells are also facilitated by the lactoferrin. The antiviral actions of lactoferrin are against both DNA and RNA viruses and it inhibits viral adhesion and entry into cells and binds viral particles. Generally, camel milk lactoferrin may directly interact with viral molecules or with the viral receptor (heparan sulfate) on the cellular surfaces to prevent the virus attachment and infection. The boosting host immune system by nutritional supplements such as lactoferrin may work against SARS-CoV-2 entry and infection into the host cells. Because of the homology in genetic sequence and receptor binding domain between SARS-CoV and SARS-CoV-2, lactoferrin may inhibit the SARS-CoV-2 invasion in the same way to SARS-CoV, via binding to heparan sulfate and prevent the viral infections and epidemic. Keeping in view this fact that lactoferrin can modulate immune responses to viral infections; it may reduce severe infections. Milk lactoferrin (in particular camel milk with the highest amount of lactoferrin) as powder or tablets may be a novel promising candidate and preventative treatment for more severe cases of COVID-19. However, it needs more studies on the unique medicinal effects of camel milk lactoferrin to verify its efficacy on COVID-19 prevention and treatment.

Lactoferrin is one of a natural nutritional supplement found in the milk of livestock mammals and has immunomodulation property due to its iron withholding ability and capacity to bind to multiple cellular receptors. The antiviral ability of lactoferrin has been evaluated against many viruses including SARS-CoV which is closely related to SARS-CoV-2 (causative agent of COVID-19). Furthermore, lactoferrin also possesses anti-inflammatory efficacy and can inhibit the circulating inflammatory cytokines (e.g. Interferon γ, interleukin (IL-) 1B, IL-6, IL-12) and chemokines (CCL2 and CXCL10) which are reported to be present in higher levels in COVID-19 patients. A particular research about exploring the potential of lactoferrin against SARS-CoV-2 is highly demandable because lactoferrin might prevent the SAR...

During the last 3 weeks of pregnancy, cattle (n 120), within parity, were randomly assigned to one of three diets with different fat supplements: (a) no supplemental fat (CON), (b) supplement rich in linoleic acid (CSO), or (c) supplement rich in EPA and DHA (CFO). Eighty-four newborn Holstein calves were randomly assigned, within the prepartum diets, to one of two calf starters: no fat supplement (FC-0) or 2 % Ca-salt of unsaturated FA (FC-2). Overall, the interaction between dam diets and calf starters did not affect calf performance or any other parameter measured. Calves born from dams fed fat (CSO or CFO) performed better than calves born from dams fed CON. Namely, calves born from dams fed fat had...

The basic ratio consisted of 60% concentrate and 40% forage. In treatment CE, 22.5% of the forage (alfalfa hay and wheat straw) was replaced with C. erectus leaves and branches. The lowest amount of dry matter intake and digestibility were observed in the treatment CE (P < 0.05). The amount of milk production significantly increased (P = 0.01) in the treatment CE. The total count did not differ between treatments, but the highest amount of Lactobacillus spp. (P = 0.01) and the lowest amount of mold (P = 0.01) were observed in the treatment CE. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity decreased on days 15 (P = 0.02) and 31 (P = 0.01) of the experiment in treatmen...

In this experiment, 12 six months old lambs and average weight 30±1.5 kg were fed with 0 (control), 3 and 6 percent Scrophularia striata for one month. Feed intake, digestibility, rumination activity, blood metabolites and protozoa were measured. The results showed that the use of Scrophularia striata had no effect on dry matter (DM) and organic matter (OM) intake, body weight and feed efficiency (P>0.05). Highest digestibility of DM, OM and the protein was for 3% Scrophularia striata (P<0.05). Digestibility of NDF and ADF in treatments containing Scrophularia striata were higher than the control (P<0.05). The rumination time for dry matter and NDF was increased for 3 percent Scrophularia striata (P<0.05). The treatment of 6% significantly reduced blood urea an...

Two adult camels were used as rumen inocula donors. Fermenters were fed with 120 g of DM/d in 3 equal portions at 08:00, 16:00, and 24:00 h. The trial contained two treatments of four replicate each in a completely randomized design. The treatments consisted (DM basis) of alfalfa hay (40%) and wheat straw (60%) as the cultivable forages, and Atriplex L. (80%), Suaeda F. (10%), and Seidlitzia R. (10%) as the pasture forages. Digestibility coefficients of DM, NDF and ADF were significantly smaller (P<0.05) in cultivable than pasture forages. Digestibility of OM for cultivable forages was significantly larger (P<0.05) than pasture forages. Total VFA, acetic, propionic, butyric, valeric and iso-valeric acids concentrations were significantly lower in (P<0.01) pasture forages than cultivable forages. Endoglucanase and...

The experimental diets were including 0, 25, 50 and 100% of Subabul branches as a replacement of Alfalfa (Medicago sativa). The ingredients of diets were Alfalfa, wheat straw, corn silage, corn, barely, bran and mineral-vitamin supplement by a ratio of concentrate and forage at 50:50. Rumen fluid was taken from fistulated cow and dromedary camels and in vitro digestibility of experimental diets was determined. The obtained data were analyzed in a split plot design. The lowest digestibility of dry matter in dromedary camel (73.1%) and cattle (71.9%) was found in the treatment containing 100% of Subabul (p<0.05). But digestibility of natural detergent fiber (NDF) and acid detergent fiber (ADF) of diets containing different levels of Subabul instead of Alfalfa were not different in cow and camel (p>0.05). Digestibility of NDF and ADF in the treatment containing 100% Subabul in the cattle were 70.36 and 68.21%, respectively, and in the dromedary camel were 71.19% and 69.02%, respectively (p<0.05). Treatments containing 50 and 100 % Subabul (74.38 and 70.37%) had the lowest dry matter digestibility (p<0.05). The ADF digestibility in treatments containing 50 and 100% Subabul in compared with control treatment was 72.4 and 67.6 vs 73.5 %, respectively, and NDF digestibility was 72.45, 69.65 and 75.33 % in treatments containing 50 and 100% Subabul and control, respectively (p<0.05). As per the result, the digestibility of DM, NDF and ADF of Subabul were not different between cow and dromedary camel (p>0.05).The result of these experiments showed that in vitro digestibility of 50 % Subabul instead of Alfalfa in diet of cow and camel was better than other levels, therefore it can be used in cow and dromedary camel nutrition.

Four fistulated dromedary adult camels were fed with diets as a changeover design, 30 days for each period. The diets included alfalfa hay + wheat straw (C3 forage) and atriplex+ suaeda + seidlitzia (C4 forage). At the end of the experiment, rumen and blood parameters, gas production of wheat straw and atriplex as a 2 × 2 factorial experiment were determined. The highest blood glucose and urea nitrogen levels were found for camels fed with C3 forage, 2 hr after feeding (p < 0.05). The maximum NH3-N concentration in the rumen was for diets C3 and C4, 2 and 4 hr after feeding (p < 0.05). The lowest rumen pH was observed for C3 diet at 2 and 4 hr and for C4 diet at 4 and 8 hr after feeding. The activity of rumen carboxymethylcellulase (CMCase) and microcrystalline cellulase (MCCase) enzymes was the highest for C3 and C4 diets, 8 hr after feedin...

At the first, 200 common carp fish (1.00 g) in two water tanks were used for producing biofloc. Then, 12 goats (average body weight of 32.00 ± 1.50 kg aging eight months) were assigned through a completely randomized design to two treatments (six replicates) and fed for one month. The treatments were comprised of a control diet and a trial diet containing 1.50% biofloc. At the end of the experiment, digestibility of nutrients, rumen fermentation, blood metabolites, and rumination activity were measured. The results showed that the digestibility of dry matter (DM), crude protein, neutral detergent fiber (NDF), and acid detergent fiber (ADF) significantly increased in goats fed with 1.50% biofloc. Also, the rumen protozoa population, plasma glucose, average time of eating, rumination, and chewing per NDF a...

The data set was comprised 80381 test day records (milk, fat and protein traits) belonging to 80254 first parity cows in 427 herds with calving year between 1995 and 2009. Based on fat to protein percentages for the first month of the lactation and also with respect to threshold point of -0.12, dependent variable was defined as a dichotomous (zero code for lack of MFD and unit code for MFD) variable. A logistic mixed generalized linear model was fitted on the data using GLIMMIX procedure of SAS software. In the model, fixed effects of sperm type (local or exotic), production season, first calving age, cow type (grade or pure Holstein) and random effect of animal’s sire were included. Cow type had no significant affect on MFD. Estimation of odds ratio for comparing different ages w...
