Опубликована: Март 1, 2025

Abstract This study investigates the impact of urea molasses-treated wheat straw on growth performance and nutrient digestibility in Azikheli buffalo male calves. A longitudinal experiment was conducted sixteen calves, randomly assigned to four experimental dietary treatments ( n = 4 per group). The diets included a control group (U0) with untreated three groups where replaced 33% (U33), 66% (U66), or 100% (U100) total mixed ration. Results indicated that increasing proportion urea-treated from 0 led significant improvements dry matter intake (from 2931 4034 g/day) organic 2596 3623 g/day). Digestibility matter, crude protein, fiber also followed an trend, reaching 77.42%, 81.21%, 87.10%, 60.22%, respectively, at highest level. Furthermore, weight gain significantly greater calves fed straw, by those U66, U33, U0 groups. Feed conversion efficiency improved substantially U100 U66 than U33 U0. These findings suggest incorporating higher levels UMTWS rations enhances digestibility, promoting superior feed

Animal health and nutrition: metabolic disorders in cattle and improvement strategies

Frontiers in Veterinary Science, Год журнала: 2025, Номер 12

Опубликована: Март 25, 2025

The health and productivity of cattle are significantly compromised by metabolic diseases on a global scale. These disorders disrupt normal processes, leading to substantial economic losses for the livestock industry. Metabolic can arise from defective biochemical pathways, deficiencies in enzymes, coenzymes, or cofactors, may be either inherited acquired. Dairy cows particularly susceptible during transition period late lactation early management, facing conditions such as ketosis, milk fever, hepatic lipidosis. This susceptibility is primarily due reduced dry matter intake caused fetal development decline rumen capacity. negative energy balance (NEB) this phase, characterized elevated blood concentrations non-esterified fatty acids (NEFAs) increased mobilization, closely linked onset these diseases. Providing high-energy-density diets critical mitigating effects NEB. represent major challenge cattle, adversely affecting animal welfare agricultural output.

Two years of precision livestock management: harnessing ear tag device behavioral data for pregnancy detection in free-range dairy cattle on silage/hay-mix ration

Frontiers in Animal Science, Год журнала: 2025, Номер 6

Опубликована: Март 31, 2025

Introduction The aim of this study was to evaluate the transformative potential precision livestock farming (PLF) in dairy production, nutrition, and reproductive efficiency by implementing proactive management strategies that utilize real-time data. Methods Data were gathered from a commercial farm, employing 3D accelerometer system attached ear-tags monitor activity rumination behavior. Additionally, information on animal-related events such as oestrus, artificial insemination, clinical diseases, treatments recorded. Results It observed there differences between positive negative cows days following insemination (AI). Specifically, day 0 16, exhibited higher time compared cows, with contrast being particularly significant 9 10. Over duration study, tested produced, average, 0.78 kg more milk per day. Discussion This suggests animals production less likely be pregnant, potentially due increased nutrient allocation mammary gland, resulting pronounced energy balance consequently lower conception rates. Furthermore, utilized capable distinguishing daily lying pregnant non-pregnant oestrus return. finding highlights for developing alert identify “probable pregnant” non-pregnant” animals.

Rhodotorula Yeast Culture Improved the Antioxidant Capacity, Lipid Metabolism, and Immunity of Sheep Livers

Veterinary Sciences, Год журнала: 2025, Номер 12(4), С. 314 - 314

Опубликована: Март 30, 2025

There is currently no research on the application evaluation of R. mucilaginosa yeast culture (RYC) in animal production. Therefore, this study investigated effects RYC antioxidant capacity, lipid metabolism, and immunity sheep livers. Twenty-four 3-month-old Duhan male (36 ± 4 kg) were divided into four groups. The control group received a basal diet, L diet + 10 g/sheep/day RYC, M 20 H 40 RYC. trial lasted for 75 days. results showed that content glutathione peroxidase livers was significantly increased by 26.6%, malondialdehyde decreased 38% (p < 0.05). Additionally, serum levels total cholesterol, triglycerides, high-density lipoprotein low-density cholesterol decreased; liver C16:0 C18:2n6C C20:1 Furthermore, contents cytokines TNF-α IFN-γ from also 20% 24.8%, respectively These findings suggest supplementation with can enhance improve reduce inflammation livers, which advantageous farming healthy sheep.

This study evaluates the impact of dietary supplementation with hemp-based polyunsaturated fatty acids (PUFAs) on membrane lipid profiles and reproductive performance Martina Franca jacks. Over a 90-day period, twelve donkeys were divided into treatment group receiving hemp oil control standard diet. Semen blood samples collected analyzed at multiple time points for composition parameters. Results revealed that sperm motility improved significantly, increasing from 92.61% in to 96.63% by Day 60 ( p = 0.05). Normal morphology also showed significant enhancement, rising 96.58% 98.85% 0.04). Conversely, gel-free semen volume decreased significantly group, 64.17 mL 28.20 &lt; 0.0001).

Опубликована: Июль 8, 2024

Poland is one of the leading milk producers in EU, being fifth largest after countries such as Germany, France, Italy, and Netherlands. From Poland's accession to European Union 2004 up 2022, Polish production experienced dynamic development. In this, there occurred a strong decline number dairy farms (by -78%) cows -21%), an increase herd size (3.5 times) (+60%) yield per cow +62%). These were among highest growth dynamics analysed countries. As result this significant transformation, maintained important position exports, with 31% export share 2022. The scale was basic factor determining efficiency competitiveness Poland. Milk yield, farmland productivity, labour price, Corrected Competitiveness Index (based on land opportunity costs) all showed positive relationship farm. highly uncompetitive for smaller (<15 cows). Despite substantial public support, farms, where subsidies equal 47% total value, could not earn sufficient income cover cost capital, risk, management 2008, even more so 2021. This because farm too small extremely high labour. larger (with 30 more) are competitive responsible majority (~60-70%) produced delivered market. most challenging from sectoral policy point view medium (10-29 cows), whose deliveries still important. To survive economically viable units, these have improve productivity. Otherwise, they will be gradually supplanted by farms.
