Abstract

Growing concerns regarding antibiotic use in livestock, due to antibiotic resistance and potential human transmission, have led to increased interest in herbs and their derivatives, including essential oils, which possess antimicrobial properties that may enhance overall productivity and serve as a strategy for methane mitigation. The objective of this meta-analysis was to investigate the effects of adding oregano to the diet in different forms (essential oils, plant materials, or leaves) on the dry matter intake (DMI), milk yield (MY), milk components, nutrient digestibility, ruminal fermentation parameters, and methane (CH4) emissions of dairy cows. A literature search was conducted to identify papers published from 2000 to 2023. Effect size for all outcomes was reported as a standardized means difference (SMD) and raw means difference with 95% confidence intervals. Heterogeneity was determined using the Q test and I2 statistic. The results of the meta-analysis indicated that adding oregano had no effect on DMI (SMD = 0.081; p = 0.507) and MY (SMD = 0.060; p = 0.665). Milk fat percentage, milk protein percentage, and milk lactose percentage were not affected by oregano. The addition of oregano to the diet significantly decreased dry matter digestibility (SMD = −0.502; p = 0.013), crude protein digestibility (SMD = −0.374; p = 0.040), and neutral detergent fiber digestibility (SMD = −0.505; p = 0.014). Ruminal pH (SMD = −0.122; p = 0.411), total volatile fatty acids concentration (SMD = −0.038; p = 0.798), acetate (SMD = −0.046; p = 0.757), propionate (SMD = 0.007; p = 0.960), and butyrate (SMD = 0.037; p = 0.801) proportion were not affected by oregano. The addition of oregano to the diet tended to decrease CH4/DMI (SMD = −0.275; p = 0.095) but did not affect CH4 production (SMD = −0.156; p = 0.282). Heterogeneity (Q and I2) was non-significant for all parameters. We conclude that the inclusion of oregano in various forms (essential oils, plant materials, or leaves) in the diet of dairy cows reduces nutrient digestibility but does not significantly affect DMI, MY, milk components, ruminal fermentation parameters, or CH4 production. Future research should focus on optimizing the dosage of oregano (both EOs and plant materials) and exploring the impact of its form on lactation, nutrient digestibility, ruminal fermentation, and CH4 emissions in dairy cows.

Abstract

A meta-analysis was conducted to analyze the effects of different dietary vegetable sources rich in unsaturated FA (UFA) on sheep cheese FA profile. This study also quantified the overall effect of feeding sheep with vegetable sources rich in UFA (linseed, flaxseed, sunflower seed, canola, olive oil, bran oil, and olive cake), on milk yield (MY) and milk composition. A literature search was conducted to identify papers published from 2000 to 2019. Effect size for all parameters was calculated as standardized mean difference. Heterogeneity was determined using I2 statistic, while meta-regression was used to examine factors influencing heterogeneity. Effect size was not significant for MY, milk fat percentage (MFP), and milk protein percentage (MPP). Dietary inclusion of vegetable sources rich in UFA decreased the effect size for C12:0, C14:0, and C16:0 and increased the effect size for C18:0, C18:1 t-11, C18:1 c-9, C18:2 c-9, t-11, C18:2 n-6, and C18:3 n-3. Heterogeneity was significant for MY, MFP, MPP, and overall cheese FA profile. Meta-regression revealed days in milk as a contributing factor to the heterogeneity observed in MFP and MPP. Meta-regression showed that ripening time is one of the factors affecting cheese FA profile heterogeneity while the type of feeding system(preserved roughages vs. pasture) had no effect on heterogeneity. Overall, inclusion of dietary vegetable sources rich in UFA in sheep diets would be an effective nutritional strategy to decrease saturated FA and increase polyunsaturated FA contents in cheeses without detrimental effects on MY, MFF, and MPP.

Abstract

Background: herbs are among the feed supplements under investigation that could replace antibiotics to improve humoral and cellular immune response in birds. Objective: this study evaluated the potential of Aloe vera (Aloe barbadensis Miller) and vitamin E as immunostimulants on humoral and cellular immune responses in broilers. Methods: broilers were randomly assigned to three dietary treatments: a negative control (basal diet+ with no additive), basal diet + 1% Aloe vera gel in drinking water, and basal diet + 100 mg/Kg vitamin E in the feed. Antibody titers against sheep red blood cells and Newcastle disease virus were used to examine the humoral immune response, whereas cellular immune response was evaluated using the phytohemagglutinin-P tests. Results: the highest level of antibody titer against sheep red blood cells on examination days 28 and 38, and the highest response to injection of phytohemagglutinin-P on day 38 was observed in the Aloe vera gel group (p0.05). In addition, the greatest antibody level against Newcastle disease virus was obtained on days 25 and 35 in the vitamin E group, with no significant difference from the Aloe vera gel group (p>0.05). Conclusion: in general, our findings demonstrated that both Aloe vera gel and vitamin E can enhance humoral and cellular immune responses of broilers, while Aloe vera gel can be used as an immunostimulant in chickens. Resumen Antecedentes: en la industria avícola, es particularmente importante mejorar el rendimiento del sistema inmune con el objetivo de incrementar la resistencia contra patógenos. Las plantas están dentro de los suplementos alimenticios que podrían reemplazar a los antibióticos con el propósito de mejorar la respuesta inmune humoral y celular en aves. Objetivo: el presente estudio evaluó el potencial del Aloe vera (Aloe barbadensis Miller) y la vitamina E como inmunoestimulantes sobre la respuesta inmune humoral y celular en pollos de engorde. Métodos: los pollos de engorde fueron asignados aleatoriamente a tres tratamientos (dietas): un control negativo (dieta base sin aditivo), dieta base + 1% de gel de Aloe vera en el agua de bebida, y una dieta base + 100 mg/Kg de vitamina E en el alimento. Se usó la titulación de anticuerpos contra glóbulos rojos de oveja y contra la enfermedad viral Newcastle para examinar la respuesta inmune humoral. La respuesta inmune celular fue evaluada usando las pruebas de fitohemaglutinina-P. Resultados: el mayor nivel de titulación de anticuerpos contra glóbulos rojos de oveja en los días de experimentación 28 y 38, y la mayor respuesta a la inyección de fitohemaglutinina-P en el día 38 se observó en el grupo del gel de Aloe vera (p0,05). Además, el más alto nivel de anticuerpos contra la enfermedad viral Newcastle fue obtenida en los días 25 y 35 en el grupo que recibió vitamina E, sin diferencia significativa con respecto al grupo con gel de Aloe vera (p>0,05). Conclusión: en general, nuestros resultados demuestran que tanto el gel de Aloe vera como la vitamina E pueden mejorar la respuesta inmune humoral y celular en pollos de engorde, mientras que el gel de Aloe vera (agregado al agua) puede usarse como un inmunoestimulante en pollos de engorde. Resumo Antecedentes: na indústria avícola, a melhoria nas respostas do sistema imunológico é importante, no sentido de aumentar a resistência contra patógenos.

Abstract

Prohibition of application of antibiotic growth promoters in broiler chicken diets has resulted in increased use of herbs as natural additives in broiler feeds over the recent years. Researchers particularly look for herbs that can affect such parameters as growth performance, immune response, or treatment of certain diseases. Aloe vera is a well-known herb characterized by properties such as anti-bacterial, anti-viral, anti-fungal, anti-tumor, anti-inflammatory, immunomodulatory, wound-healing, anti-oxidant, and anti-diabetic effects. During the past years, attention has shifted toward Aloe vera as a natural additive to broiler diets, and studies have shown that Aloe vera can improve immune response and growth performance in broilers. In addition, Aloe vera is an excellent alternative for antibiotic growth promoters and anticoccidial drugs. Since Aloe vera can be used for broilers in the form of gel, powder, ethanolic extract, aqueous extract, and a polysaccharide contained in Aloe vera gel (i.e. acemannan), more studies are required to determine the best form and to compare Aloe vera with other medicinal herbs. This paper reviews effects of Aloe vera on intestinal microflora, growth performance, immune response, and coccidiosis in broiler chickens.

Abstract

Given the currently increased focus of researchers on applications of medicinal herbs as a natural additives to animal and poultry feed for enhanced performance of the immune system, the present study aims to examine effects of peppermint, Aloe vera, and Vitamin E on immune response in broilers. In this experiment, three hundred one-day old male broilers (Ross 308) were used on a completely randomized design in 4 groups with 5 replicates, each consisting of 15 broilers. The experimental groups included the control group (basal diet with no additive), a group that received 10 g/kg dry peppermint leaves (added to basal diet), a group given 10 g/kg Aloe vera gel (added to basal diet), and a group treated with 100 mg/kg Vitamin E. Evaluation of antibody titer against Newcastle disease virus indicated that on day 27, the highest level of antibody titer was observed in the Vitamin E group, showing a significant difference from other groups (P<0.05) except for the group that received the dry peppermint leaves. On day 37, the highest level of antibody titer against Newcastle disease virus was found in the Vitamin E group with a significant difference compared to the herb groups (the groups that received dry peppermint leaves and Aloe vera gel) as well as the control group (P<0.05). On the other hand, on days 27 and 37, the groups that received dry peppermint leaves and Aloe vera gel showed significant increase in their antibody titer against Newcastle disease virus compared to the control group (P<0.05). The results after injection of phytohemagglutinin-P on day 40 demonstrated that broilers in the Aloe vera gel group and those belonging to the dry peppermint leaves group significantly enhanced their response to phytohemagglutinin-P solution compared to the control group and to the broilers that were given Vitamin E (P<0.05). On day 42, a significant increase was observed in total white blood cell counts of broilers in the Aloe vera gel group and the dry peppermint leaves group compared to the control broilers, although the largest number of white blood cell was found in the broilers that received Vitamin E (p<0.05). In general, our results showed that supplementation of broiler feed with either dry peppermint leaves or Aloe vera gel enhances immune response. [ABSTRACT FROM AUTHOR]

Abstract

The present study attempts to analyze the effects of different levels of Aloe vera gel as an alternative to antibiotic, on performance and ileum morphology in broilers. Three hundred one-day old Ross 308 male broilers were used on a completely randomized design in 5 groups with 4 replicates, each consisting of 15 broilers. The groups included the control group (basal diet) and three groups with basal diet mixed with different levels of Aloe vera gel (1.5%, 2% and 2.5%). Finally, there was a group with basal diet plus 15 ppm antibiotic virginiamycin. The results obtained regarding performance of the broilers showed that Aloe vera gel groups brought about higher body weight gain and feed intake compared to the control group; however, no significant difference was observed in feed conversion ratio between the groups treated by Aloe vera gel and the control group (P>0.05). Although the antibiotic group showed better performance and heavier dressing percentage than the Aloe vera gel and the control groups, no significant difference was seen between the group treated by 2% Aloe vera gel and the antibiotic group regarding body weight gain, feed conversion ratio and dressing percentage (P>0.05). Among the Aloe vera gel groups, the 2% Aloe vera gel group had the largest villus height and the greatest villus height to crypt depth ratio compared to the antibiotic group (P<0.05). In general, 2% Aloe vera gel treatment may be recommended to achieve the best performance in broilers as an alternative to antibiotic growth promoter. [ABSTRACT FROM AUTHOR]

Abstract

Mixing nitrogen-stabilizing leguminous forages such as Vicia spp. with livestock feeding systems like farm-pasture or farm-animal systems is one of the best approaches to reserve seasonal feeds, to decrease the load on pasture, and to increase soil fertility. The objective of this study was to determine the chemical compositions and fresh/dry forage yield of three varieties of Vicia spp. (Vicia narbonensis, narbon vetch, accession 2561; Vicia sativa, common vetch, accession 463; Vicia dasycarpa, woolly-pod vetch, accession 2446) at full blooming stage. The plants were grown under the climatic conditions of the province of Lorestan in Western Iran and were harvested at full blooming stage. Fresh and dry forage yields, as well as protein yield, were significantly higher (P<0.05) in narbon vetch (28847, 7366 and 1400 kg per hectare, respectively) than in woolly-pod (24825, 4884 and 1050 kg per hectare, respectively) and common vetch (20727, 6061 and 564 kg per hectare, respectively). Woolly-pod vetch had the highest content of crude protein (21.5%) and ash (12.3%), while common vetch had the highest content of neutral detergent fibre (43.9%). There was no difference in degraded dry matter (DDM) between the Vicia varieties in vitro. Results showed that all the Vicia varieties provide high quality forage for livestock, and can be recommended for cultivation because of their adaptability to the particular conditions of a region.
