Grazing cows could produce milk with a higher proportion of polyunsaturated fatty acids, which is beneficial to human health, compared non-grazing cows, though grazing alone compromise production. Under oceanic climate conditions, study involving 15 dairy fed total mixed ration (TMR) ad libitum in combination different times 12 h (TMR12), 6 (TMR06) and zero time (TMR00) the aim evaluate strategies on acids profile No differences were seen between treatments respect yield (34·4±6·3 kg/d) or...
Abstract In recent years, consumer attitudes toward fat of animal origin have changed owing to findings that some milk fatty acids (FAs) are positive for human health, especially conjugated linolenic acid and n -3 FAs. Accordingly, the manipulation content FA composition cows’ via nutritional strategies has been an important target dairy industry in many countries. Twenty commercial Holstein–Friesian herds Asturias (northern Spain) with 1106 cows were examined order evaluate profiles under...
This study examines the relationship between subclinical ketosis (SCK) in dairy cows and butyric acid content of silage used their feeding. Twenty commercial farms were monitored over a period 12 months. The feed at each farm silages its ration sampled monthly for proximal analysis volatile fatty analysis. A total 2857 urine samples taken from 1112 to examine ketonuria about 30 days prepartum 100 postpartum. Wide variation was recorded quality preparation diets. Approximately 80% analyzed...
Forage ensilability mainly depends on dry matter (DM), water soluble carbohydrates (WSC) and buffer capacity (BC) values at harvest time. According to these parameters, based a collection of 208 forages known characteristics including short long term meadows for grazing, italian ryegrass, maize, triticale, soybean, faba bean crops, samples coming from cereal-legume associations, the objective this study has been define quantitative index (EI) relationship between DM, WSC BC contents date,...
This study was carried out using a spectral database consisting of 394 samples fresh total mixed ration (TMR) from dairy farms located at Northern Spain. Cloning sets different size and structure were evaluated for the transfer large TMR obtained on Foss NIRSystems monochromator to 2 portable near-infrared devices: one diode array instrument another based linear variable filters. The cloning matrix that produced best matching between instruments then used library instruments. Once had been...
The possibilities of using high quality pastures in conjunction with total mixed ration (TMR) during the grazing season have been examined. An experiment sixteen Holstein cows blocked and randomly assigned to four treatments a factorial arrangement was conducted order evaluate influence time day (day or night) type silage (maize Italian ryegrass) included TMR dairy 12 h daily on milk yield, composition fatty acid profile. had no effect dry matter intake, yield fat protein proportions....
Milk casein and fraction contents have a great influence on milk rennet properties cheese yield so that the selection of dairy cattle with genetic characteristics suitable for transformation is interest to farms firms. The possibility rapid accurate determination these parameters would be very useful predict aptitude making. This work aimed determine fractions their variants content using near infrared (NIR) spectroscopy in reconstituted samples by comparing performance different NIR...
Selenium (Se) enrichment improves milk functional nutrient content enhancing its nutritive value and providing health benefits. This Se enriched can be considered as “nutraceutical” or “functional food”. However, this benefit should not affect negatively other properties, such trace element contents. Holstein-Friesian cows diets were supplemented with increasing dosages in order to obtain on-farm milk, metals including Co, Cu, I, Zn determined these samples. Our results showed that...
Milk fatty acid (FA) profiles of lactating Holstein dairy cows were determined to evaluate the effects parity (primiparous or multiparous) and grazing time (0, 6 12 h), complementary a total mixed ration, in 2 × 3 factorial design. The interaction with did not affect milk production protein content; however, dry matter intake herbage, fat content affected by (P < 0.05). Both factors concentration monounsaturated FAs. 18 : cis9 cis12, trans11, cis12 cis15 concentrations higher 0.05)...
Near infrared spectroscopy coupled to a microscope (NIRM) is technique where the beam focused on each particle (< 50 μm) of sample collect NIR spectra. In this work, experimental conditions (sample pre-treatment and instrumental) have been evaluated compared for collecting spectral information in order develop strategy able build large robust libraries be transferred between NIRM instruments. To attempt objective, we selected most representative ingredients included animal feeds: straw as...
