A tremendous evolution has taken place in the field of equine reproduction during past decade.Advanced techniques, such as ovum pick up combined with intracytoplasmic sperm injection and embryo transfer, have become more routine procedures warmblood breeding.These techniques allow 'popular' mares to produce multiple foals per year via surrogate mares.The latter impression that only a limited number popular stallions are preferred by breeders due strong selection, could generate fast-paced...
The effects of restricted time allocation (2, 4 or 6 h/day) to pasture and grazing day (Day 1, initial; Day 4, intermediate; 7, final) on feeding behaviour, intake performance were assessed in Sarda dairy ewes, rotationally Italian ryegrass plots for 7 days, with 21 days regrowth. A randomised block design two replicates per access was used six groups ewes each. supplemented daily 400 g/head a commercial concentrate at milking, 300 lupin after 700 hay overnight. Pasture variables, herbage...
Abstract The effects of restricted access time to pasture (2, 4 or 6 h d −1 ; 2H, 4H 6H) on ingestive behaviour and performance were assessed four occasions per target grazing day (D1, initial day; D4, intermediate D7, final day) in dairy ewes rotationally berseem clover with a 7‐day period 21‐day recovery period. A randomized block design two replicates treatment was used. All supplemented daily 700 g head concentrates ryegrass‐based hay. Pasture subplot animal group data analysed by...
Knowledge of how grazing cattle utilize heterogeneous landscapes in Mediterranean silvopastoral areas is scarce. Global positioning systems (GPS) to track animals, together with geographic information (GIS), can relate animal distribution landscape features. With the aim develop a general spatial model that provides accurate prediction resource selection patterns within mountainous area, free-roaming Sarda cows were fitted GPS collars their behaviors. Resource function models (RSF) developed...
An experiment was carried out to study the excretion of aflatoxin M1(AFM1) in milk three goats fed a single dose (0.8mg/head) pure B1 (AFB1). The values AFM1 concentration excreted highly variable among goats, even if pattern over time very similar animals. first detected at milking performed 1h after AFB1 administration. highest were reached 3 and 6h intake. trend clearance expressed by decreasing exponential equation. below EU maximum allowed level (50 ng/L) collected 36 h
ReferencesA trial on different fatty acid supplementation was run in grazing dairy sheep. Forty-eight lactating Sarda ewes were randomly allocated to four homogeneous groups: PAS, control group for 22h/d without supplementation; NOF, supplemented with a cereal based non-fat enriched concentrate; C182, concentrate rich sunflower seeds; and C183, linseeds. The results showed that the concentrates, oilseeds from both linseed sources determined high C18:1 t11 CLA c9 cheese fat content. Moreover...
This work evaluated the reliability of multivariate statistical analysis to discriminate feeding system and species ruminants using their intramuscular fatty acids (FA) profile. FA composition 53 meat samples (longissimus dorsi muscle) from animals different (sheep cattle) raised with systems (pasture stall-fed) (4 groups overall) was determined expressed as % acid methyl ester (FAME). A stepwise discriminant (SDA) applied full set select variables that best discriminated between animal...
The beef livestock system in Sardinia is based on suckler cows, often belonging to autochthonous breeds, such as the Sarda breed, and they graze silvopastoral areas. Besides meat, systems (SPSs) provide several Ecosystem Services (ESs), timber provision, harvested wood, watershed protection. Livestock distribution a critical factor for sustainable use of SPSs (e.g., avoid uneven grazing patterns) information patterns spatial are required. A study was conducted determine: (i) (ii) habitat...
The fatty acid profile, vitamins A and E, cholesterol, antioxidant power colour the phenols profile of Sarda sheep milk from 11 commercial flocks managed under permanent grassland were investigated. In each farm, structural managerial data samples collected during four periods (sampling dates, SD): January, March, May, July. Data composition (fat, protein, casein, lactose, somatic cell count), 68 acids, 7 phenols, 1 total gallocatechin equivalent, ferric reducing power, degree protection, (b...
Context Recent heightened interest of consumers in the origins their food, together with broader general awareness environmental matters, has led to an increase demand for meat obtained from grazing systems. The importance local breeds adapted medium- and low-input production is fully recognised as a means guaranteeing sustainability these farming methods. A finishing system based on pastures use could both meet demands economic returns Sardinian farmers. Aims work evaluated effects...
Milk from grazing ruminants is usually rich in beneficial components for human health, but distinguishing milks sourced difficult, and this hinders the valuing of benefit. This study aimed at evaluating ability milk biomarkers (1) to trace sheep submitted different access times (ATs) pasture (2) estimate herbage dry matter intake (HDMI, g DM ewe −1 d ) percentage (HP, % DM) diet. Animal data derive a published experiment which six replicated groups mid-lactation Sarda had ATs 2, 4, or 6 h...
The work aims to fill the knowledge gap on performance and meat quality of “Agnello di Sardegna” PGI light lambs. To this end fourteen male lambs, homogeneous for age litter size consisting seven pure Sarda (S X S) crossbred Ile de France x (IF lambs were compared growth rate, dressing-out percent, chemical composition, fatty acids (FA) composition Longissimus lumborum muscle some nutritional indexes. Lambs suckled followed their mothers at pasture until slaughtering at17±3 kg Live Weight...
This work aimed to compare pre- and post-slaughter methodologies estimate body fat reserves in dairy goats. Twenty-six lactating Saanen goats ranging from 43.6 69.4 kg of weight (BW) 1.84 2.96 condition score (BCS; 0–5 range) were used. Fifteen pre-slaughter four measurement values used the omental (OM), mesenteric (MES), perirenal (PR), organ (ORG), carcass (CARC), non-carcass components (NC) total (TOT, calculated as sum CARC NC) depots The measurements withers height; rump length; pelvis...
Free-roaming Sarda cows grazing a Mediterranean silvopastoral area were fitted with Global Positioning System (GPS) tracking collars to estimate daily distance travelled (DT), (DW) and maximum (DWM) water, proportion of time (PT) the near water source, in different seasons physiological status (dry lactating). From herd 12 54-ha pasture, characterised by deciduous oak wood glades, three (N=3) Knight GPS collar during four sampling periods (one per season, from 26/02/19 16/10/2019). Collars...
