Heat stress (HS) occurs when animals are enable to effectively dissipate excessive body heat, potentially affecting their welfare and productivity. Several tools can be used mitigate HS in dairy cows. The aim of this study was evaluate the effect thermoregulatory mineral supplementation on cows' physiological response reproductive status. Thirty pluriparous Holstein cows (2.8 ± 0.3 lactation), from a semi confinement production system (freestall barn), were enrolled 35 days duration...

The aim of this study was to evaluate the effects a complete hay-based total mixed ration (TMR) for calves, focusing on their feed intake, animal growth performance, and fecal output, develop preliminary estimation equation solid intake body weight in Holstein heifer calves. Twenty female Italian calves (37.14 ± 2.72 kg) born between February July were studied from day birth until 77 days age. From fourth life, they fed 3 L/day pasteurized milk twice daily supplemented with same TMR. data...

The present study aimed to investigate the association between stayability (STAY) traits, muscularity, and body condition score (BCS) in Italian Simmental dual-purpose cows. Data were collected from 2,656 cows linearly scored their first lactation 2002 2020 reared 324 herds. binary trait STAY, which is ability of a cow stay herd, was obtained for each cow-lactation available up parity 5 (from STAY1-2 STAY4-5). Analysis STAY carried out using logistic regression, considering fixed effect...

This study investigated the effect of gaseous ozone (O3) on chemical and microbiological properties whole-plant corn silage. Conducted a commercial dairy farm in Brazil, maize was ensiled experimental bag silos treated with varying levels O3 (0%, 1.25%, 3.12%, 4.15%, 6.25%). The findings revealed minimal nutrient losses starch, non-fiber carbohydrates, crude protein, total digestible nutrients compared to untreated fresh maize. O3-treated silages exhibited increased ash, ether extract,...

This study evaluates Instagram's efficacy as an educational tool in veterinary sciences, focusing on dairy cow nutrition and management. Using the Instagram account "Stalla Didattica Unibo," established December 2020, a survey was conducted with 102 respondents, primarily consisting of university students (44.12%). The respondents were divided into 2 major groups: general population, latter comprising professionals others not currently programs. In overall age group 25-34 accounted for 51%,...

Dairy cows are exposed to multiple stressors during the productive cycle, such as metabolic challenges, overcrowding, grouping change, environmental stress and dietary errors. Thus, it is essential study reliable markers able detect conditions in dairy farms. This evaluates cows' immunologic after sudden combined exposition a high-grain diet (75% concentrates) abrupt change of housing system (from free stall tie stall). A group twenty-four Holstein were enrolled challenge 28 days duration....

The aim of this study was to develop near-infrared spectroscopy (NIRS) prediction models for the estimation chemical components and fibre undegradable fractions (uNDF) hay-based total mixed rations (TMR). A 205 TMR samples were used study. All measured using standard AOAC reference methods expressed as percentages dry matter (DM). Prediction developed both cross- independent validation different mathematical treatments applied on spectral data. best treatment chosen based method which...

This work investigates the effects of structural modifications on welfare level and laying patterns hens in a three-tier commercial aviary system. Four experimental groups were used: C (control, housed traditional aviary); LM (longitudinal movement, which internal partitions removed); VM (vertical ramps installed); FM (freedom both modifications). Hens showed worse body condition scores (p < 0.05) all modified aviaries, while plumage was improved but worsened 0.05). No significant effect...

We assessed the effects of inhalation administration lavender essential oil (LEO) either once (L1) or twice (L2) a day on animal welfare indicators, carcass and meat quality Italian heavy pigs. Pigs (n = 108) were allotted to three experimental groups (control -C-, L1 L2) was administered, via vaporizer device, treated during entire fattening–finishing period (79–160 kg BW). Tail lesion severity reduced in at end trial compared other (p &lt; 0.05). Body counts, however, higher L2 than C...

Longevity in dairy and dual-purpose cattle is a complex trait which depends on many individual managerial factors. The purpose of the present study was to investigate survival (SURV) rate Italian Simmental cows across different parities. Data this referred 2 173 primiparous under official milk recording that calved between 2002 2020. Only linearly classified for type traits, including muscularity (MU) body condition score (BCS) were kept. Survival analysis carried out, through Cox regression...

Circular feeds, such as grain dry distillers, citrus pulp, cane molasses, and potatoes peels, are co-products of biomass processes. They currently proposed in animal nutrition to improve the environmental economic sustainability food production chain. In this paper, we report a case study involving fipronil, pesticide not authorized for agriculture within EU, but used Americas, Eastern Europe, Asia. Fipronil was found at mean level 0.49 mg/kg, distiller batch administered dairy cows. This...

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...

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...

For this purpose, eight multiparous mid-lactating cows were blocked assigned one four treatments used a replicated 4 × Latin squares design 21-days periods (14 days adaptation 7 data collection). Two different circular feedstuffs tested: bakery’s former foodstuff (FF) wheat distiller’s...

In veterinary medicine, Cannabis has been used to treat pain conditions, inflammation, and seizures. However, little is known about its effect on dogs' behavior. This preliminary research aims address this knowledge gap by evaluating the effectiveness of cannabidiol (CBD) oil in canine behavioral therapy. Twenty dogs, diagnosed with disorders housed a municipal shelter, participated double-blind trial. Ten dogs received CBD treatment, while other ten control without CBD. Before (T0) after...
