“…and 40% graminee (Bromus catharticus, Festuca arundinacea, Lolium perenne). In previous trials (Infascelli et al, 2005;Tudisco et al, 2010;Tudisco et al, 2012) carried out in the same area, the protein content of pasture was close to 16% dry matter (DM), thus groups H and L received alfalfa hay selected to guarantee the same protein intake for all the groups. The daily intake of alfalfa hay, measured subtracting the refusals to the administered amounts, was 1.2 kg as fed/head.…”

“…In particular, many researches have focussed on the antioxidant and anticarcinogenic properties of a class of the conjugated linoleic acids (CLA) (Parodi, 1999) which come from the rumen biohydrogenation of linoleic and linolenic acids. According to some authors (Nudda et al, 2006;Tudisco et al, 2010;Tudisco et al, 2012) the levels of both these acids in animal diet could affect milk CLA contents. The aim of present trial was to evaluate the effect of pasture and linseed intake on the fatty acid profile and CLA content of milk yielded by an autochthonous goat population called "Cilentana", extensively bred in Cilento (Salerno province, Southern Italy).…”

There is great interest in producing bioethanol from biomass and there is much emphasis on exploiting The effect of pasture and of diet linseed supplementation on fatty acid profile of milk was evaluated using 45 pluriparous goats, equally divided after kidding into three homogeneous groups (H, P and L). Group H (control) and L were housed in a stall receiving alfalfa hay, while group P was led to pasture. The groups received concentrate which for group L had linseed as ingredient. Average milk yield did not statistically differ between the groups. Groups P showed significantly higher fat content than group H and L (4.62% vs 3.70%, and 3.90% respectively for groups P, H and L; P < 0.01). On the contrary, milk from goats of group H and L had significantly higher content of lactose (4.65% and 4.61% vs 4.57%, respectively for groups H, L and P; P < 0.05). The levels of C18:1 cis9, C18:1 trans11 and MUFA in milk were significantly (P < 0.05) increased by both the pasture and linseed, while linoleic acid (C18:2) and PUFA were significantly (P < 0.05) higher in group P compared either to H or to L groups. The highest values of CLAs, either as t11 CLA and t10 c12 CLA or as CLA, have been registered in milk of group P, the lowest in group H. These parameters in milk of group L were significantly (P < 0.05) lower or higher than those of group P and H, respectively.

“…Nutrition plays a pivotal role in determining metabolic status, and thus influences livestock performance, animal welfare and product quality. More particularly, several studies have demonstrated that the animal's diet greatly influences milk polyunsaturated fatty acid (PUFA) and conjugated linoleic acid (CLA) (D'Urso et al., 2008, Tudisco et al., 2010, Tudisco et al., 2012, Tudisco et al., 2014).…”

Influence of dietary hydrogenated palm oil supplementation on serum biochemistry and progesterone levels in dairy goats

et al. 2019

The aim of this research was to investigate the influence of hydrogenated palm oil (HPO) added to a dairy goat diet on serum biochemistry and progesterone levels. Thirty pregnant Cilentana dairy goats were equally divided into 2 groups (control [CTR] and HPO groups). After kidding, concentrated feed for both groups was gradually increased up to 400 g/(animal·d), and the HPO group received 50 g/(animal·d) of HPO. Supplementation with HPO significantly increased cholesterol levels (mg/dL, 63.80 vs. 54.68 at 30 d, P ≤ 0.05; 78.20 vs. 58.00 at 60 d, P ≤ 0.05; 83.80 vs. 57.83 at 120 d, P ≤ 0.01) compared with the CTR group although no significant differences were detected for liver and kidney function indicators. Moreover, other biochemical parameters were not affected by HPO supplementation thus suggesting no change occurred in lipid and protein metabolism. Furthermore, a significant correlation was found between progesterone levels and serum cholesterol (r = 0.65, P ≤ 0.01) although these were not significantly higher in HPO supplemented goats. The dose and time of HPO supplementation appears critical as regards assessing the limits between the risks and benefits of HPO supplementation in dairy goats. At the tested dose, HPO was well tolerated by the animals and may represent a useful tool to increase energy availability during highly demanding periods.

“…Tudisco et al (33) reported higher SCD1 expression in the somatic cells of milk yielded from goats bred according to either organic system than those bred in stable. The authors justify the results for a higher amount of both C18:2 and C18:3 ingested by organic group than the stable group, as registered in previous research (34,35), thus probably resulting in an up-regulation of the SCD expression.…”

Stearoyl-Coenzyme A desaturase 1 (SCD1) belongs to the fatty acid family of desaturases. In lactating ruminants, the SCD1 protein is highly expressed in the mammary gland and is relevant for the fatty acid composition of milk and dairy products. Bovine mammary epithelial cells (BME-UV1), cultured in vitro, have been proposed as a model to reproduce the biology of the mammary gland. The present study was designed to investigate the responsiveness of bovine SCD1 promoter to serum, insulin, oleic acid, and NFY transcription factor in BME-UV1 cells. A luciferase-based reporter assay was used to monitor the transcriptional activity of the SCD1 promoter region in BME-UV1 cells treated or not with insulin and/or oleic acid. The level of endogenous SCD1 mRNA was evaluated by Real time PCR. Insulin (20 ng/mL) induced a 2.0 to 2.5-fold increase of SCD1 promoter activity. Additionally, the effect of insulin was inhibited by oleic acid, serum components, and NFY enforced expression. Serum and NFY showed no synergistic or additive effect on SCD1 promoter activity suggesting that they repress SCD1 transcription through the same responsive element.
