Abstract

The current study assessed the effects of covering corn silage with tomato or apple pomace on fermentability and feed quality. The in vitro gas production test was performed using graded 100 mL syringes. Incubation times were 3, 6, 12, 24, 48, 72, and 96 h. In vitro gas generation characteristics were significantly altered by TP (tomato pomace) and AP (apple pomace), both alone and in conjunction with PE (polyethylene) films, regardless of their presence. As a result of the effects found on NH3-N concentration, aerobic stability, and yeast activity, TP and AP have the potential to become an eco-friendly alternative to PE films. The gas production from the immediately soluble fraction (a) of corn silage was only affected when the corn silage was covered with a combination of AP and PE compared to the CPE group (p < 0.001). The largest cluster includes correlations of the DOM-TDDM (r = 0.90), DOM-AA (r = 0.88), and Ash-TDDM (r = 0.86) correlations. The most substantial negative correlations were identified between DM-CO2 (r = −82), DM-Yeast (r = −0.79), and CF-DOM (r = −0.79). Nonetheless, the use of pomace as a silage cover presents an inexpensive alternative to plastic films for silage that does not have the environmental problems associated with persistent micro- and nanoplastics.

Abstract

Nanoscience is one of the newest technologies in the world that is widely used in all fields of science and technology such as agriculture, medicine, pharmacy, environment, etc. One of the reasons for the pervasiveness of this technology in all sciences is related to its cross-science nature. This technology has received more attention in recent years due to its low cost, better and faster performance, high stability, and high repeatability. With this technology, farmers can have animals of superior breed and high production and experience the best performance by minimizing various diseases and have a high efficiency of milk and meat production at a lower cost.

Abstract

In recent years, researchers from various fields have tried to use them because of the increasing growth of nanotechnology. Technological applications in animal health have been a significant problem. However, it has overturned into a recent enabling technique over the years, with the vast possibility of transformation, and has potentially developed solutions. Nanotechnologies offer a wide range of prescription drugs for the diagnosis and treatment of diseases and reproduction. Nano-vaccines have emerged as a novel method of vaccination and are many more effective than traditional vaccines. Nano-vaccines trigger immune responses in the bloodstream and cells and prevent the spread of infection by destroying infectious agents by controlling the immune system. Also, advances have been reported in developing DNA-based vaccines for many diseases compared to conventional therapies. Objective: This review article aims to gather the materials and research that has been done to clarify the potential roles of nano-vaccines on animal health and their potential benefits and risks.

Abstract

This study aimed to investigate the effects of slaughter age (young vs. old), muscle type (Longissimus dorsi (LD), Gluteus medius (GM)) and fat deposits (kidney knob and channel fat, subcutaneous fat, intramuscular fat) on chemical, organoleptic, textural characteristics and fatty acid composition of Holstein Friesian bull meat. For this purpose, the carcasses of 26 Holstein Friesian bulls that had been fattened on the same private farm were assigned to two experimental groups based on their age at slaughter: a young group (YG) (average age: 17.0 ± 1.0 months old) and an old group (OG) (average age: 22.0 ± 1.0 months old). The percentage of crude protein, panel tenderness score, polyunsaturated fatty acid (PUFA) and saturated fatty acid (SFA) content, the PUFA/SFA ratio and the hypocholesterolemic fatty acid (DFA)/hypercholesterolemic fatty acid (OFA) ratio of the bull carcasses decreased significantly with increasing slaughter age. By contrast, the OFA content of the carcasses significantly increased (p < 0.05) with increasing slaughter age. Advanced slaughter age resulted in lower panel tenderness scores. Additionally, the meat of the bulls in the OG was considered to be less healthy because of the less desirable fatty acid composition and nutritional indices, such as the PUFA/SFA and hypocholesterolemic/hypercholesterolemic ratios, compared to the meat from the bulls in the YG. Furthermore, the intramuscular fat and internal fat contained high percentages of PUFA and SFA and high PUFA/SFA and hypocholesterolemic/hypercholesterolemic ratios. Interestingly, the percentage of OFA content in the internal and intramuscular fat tissues decreased with increasing slaughter age. In conclusion, this study provided evidence that slaughter age and muscle and fat type are essential sources of variations in the textural characteristics, sensory panel attributes and fatty acid profile of meat from Holstein Friesian bulls.

47. Influence of nitrate supplementation on in-vitromethane emission, milk production, ruminal fermentation, and microbial methanotrophs in dairy cows fed at two forage levels

Abstract

Modifying the chemical composition of a diet can be a good strategy for reducing methane emission in the rumen. However, this strategy can have adverse effects on the ruminal microbial flora. The aim of our study was to reduce methane without disturbing ruminal function by stimulating the growth and propagation of methanotrophs. In this study, we randomly divided twenty multiparous Holstein dairy cows into 4 groups in a 2×2 factorial design with two forage levels (40% and 60%) and two nitrate supplementation levels (3.5% and zero). We examined the effect of experimental diets on cow performance, ruminal fermentation, blood metabolites and changes of ruminal microbial flora throughout the experimental period (45-day). Additionally, in vitromethane emission was evaluated. Animals fed diet with 60% forage had greater dry matter intake (DMI) and milk fat content, but lower lactose and milk urea content compared with those fed 40% forage diet. Moreover, nitrate supplementation had no significant effect on DMI and milk yield. Furthermore, the interactions showed that nitrate reduces DMI and milk fat independently of forage levels. Our findings showed that nitrate can increase ammonia concentration, pH, nitrite, and acetate while reducing the total volatile fatty acids concentration, propionate, and butyrate in the rumen. With increasing nitrate, methane emission was considerably decreased possibly due to the stimulated growth of Fibrobacteria, Proteobacteria, type II Methanotrophs, and Methanoperedense nitroreducens, especially with high forage level. Overall, nitrate supplementation could potentially increase methane oxidizing microorganisms without adversely affecting cattle performance.
