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...
Lactose percentage (LP) in milk is currently determined most herd-testing schemes, and globally, it usually routinely recorded the framework of official recording procedures. However, few studies have investigated phenotypic genetic variability this component. Data used present paper consisted 59 811 test-day records from 4355 Holstein cows 266 herds. Heritabilities LP lactose yield (LY) were estimated through single-trait repeatability animal models, whereas correlations LY with composition...
This study aimed to investigate factors affecting protein fractions, namely α-casein (α-CN), β-casein (β-CN), κ-casein (κ-CN), β-lactoglobulin (β-LG) and α-lactalbumin (α-LA) predicted from milk infrared spectra in of dairy dual-purpose cattle breeds. The dataset comprised 735,328 observations 49,049 cows 1782 herds. Results highlighted significant differences fractions the studied Significant variations were found also through parities lactation, with latter thoroughly influencing...
Population-level phenotyping is, for some traits, hardly achievable due to limitation of reference analyses. Mid-infrared spectroscopy (MIRS) is a quick and cost-effective laboratory technique allowing the prediction innovative milk quality features on large scale. The present study aimed at investigating factors associated with Ca, K, Mg, Na P contents predicted by MIRS models multi-breed spectral data set 123,240 test-day records. Two dairy (Holstein–Friesian Brown Swiss) two dual-purpose...
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...
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...
The aim of this research was to evaluate the productive responses cows fed a dry hay based total mixed ration (TMR) in which sorghum (SOR) or corn (COR) meal (8 kg/h/d) were main source starch. study involved two dairy herds located Parmigiano Reggiano PDO area, for 1,400 (30% primiparous and 70% pluriparous). Each herd alternatively SOR COR TMR 4 periods 3 weeks: weeks adaptation one week data collection. Total milk production composition, cheesemaking properties, fatty acid content cheese...
The aim of the present study was to develop a model predict muscularity and body condition score (BCS) during lactation Italian Simmental dairy cows in Emilia Romagna herds. A total 2656 primiparous from 324 herds were linear classified between 2002 2020. Lactation curves for BCS modelled each cow using random regression model. included fixed effects age at scoring days milk with Legendre polynomial, herd-year classification, polynomials. most parsimonious cubic polynomial effects. Results...
Milk processing attributes represent a group of milk quality traits that are important to the dairy industry inform product portfolio. However, because resources required routinely measure such traits, precise genetic parameter estimates from large population animals lacking for these traits. characteristics considered in present study-rennet coagulation time, curd-firming curd firmness at 30 and 60 min after rennet addition, heat casein micelle size, pH-were all estimated using mid-infrared...
Abstract This study estimated the effect of Holstein‐Friesian, Brown Swiss, Jersey, Simmental and Alpine Grey cattle breeds on milk mineral contents (Ca, Mg, P, K, Na) in multibreed herds using data predicted with mid‐infrared spectroscopy. The dataset included 139,821 observations from 16,566 cows 977 herds. Fixed effects considered mixed model were breed, parity, stage lactation first‐order interactions, random cow, herd‐test‐date, residual. Multiple comparisons least squares means...
Immunoglobulin G is the fundamental antibody for acquisition of passive transfer immunity in ruminant newborns. Colostrum, fact, must be administered as soon possible after birth to ensure a successful IgG from dam calf. Assessment colostrum Ig concentration and gross composition via gold standards expensive, time consuming, hardly implementable large-scale investigations. Therefore, present study we evaluated predictive ability mid-infrared spectroscopy (MIRS) an indirect determination...
Milk lactose content (LC) physiologically decreases with parity order in dairy cows, but also after udder health inflammation(s) and/or presence of elevated milk SCC subclinical cases. Therefore, the progressive decrease LC observed along cows' productive life can be attributed to a combination factors that altogether impair epithelial integrity, resulting weaker tight junctions, e.g., physiological aging epithelium, mechanical stress due milking, and experienced clinical or mastitis....
The aim of the present study was to characterise milk Burlina local cattle breed for traits technological and nutritional relevance, such as coagulation properties (MCP), protein, major mineral fatty acid (FA) composition. is mainly reared in mountain areas Veneto Region (Italy) it has been inserted conservation plans aiming avoid biodiversity loss marginal pasture abandonment. Eighty-one individual samples were collected four farms. Milk determined using Formagraph, FA composition analysed...
Milk mineral concentration is important from both the perspective of processing milk into dairy products and its nutritive value for human consumption. Precise estimates genetic parameters are lacking because considerable resources required to collect vast phenotypes quantities. The calcium (Ca), potassium (K), magnesium (Mg), sodium (Na) phosphorus (P) in present study was quantified mid-IR spectroscopy on 12 223 test-day records 1717 Holstein-Friesian cows. (Co)variance components were...
