“…Similarly, Nudda et al (2013) reported no influence on plasma γ-GT when the goats were fed a ryegrass hay-based diet supplemented with 10.5% extruded linseed. In disagreement with our results, Bianchi et al (2014) reported evidence of an increase in γ-GT activity when dairy ewes were fed silage-based diets supplemented with 6.0% palm oil for 120 days. This negative effect could be due to the nature of this lipid supplement rich in SFA.…”

ABSTRACT:The aim of this study was to evaluate the effect of dietary supplementation with hemp seed oil (HSO) on the lipid metabolism, through the plasma lipid profile, liver function and concentrations of fatty acids (FA), cholesterol, and vitamin A in goat milk. Ten Carpathian goats were divided into two groups: one was fed the control diet (C) composed of alfalfa hay and concentrate, and the other was fed C diet supplemented with 93 g/day of HSO (4.7% of dry matter intake) for 31 days. The HSO supplementation did not modify plasma cholesterol, triglyceride or phospholipid concentrations, or the activities of alanine aminotransferase or γ-glutamyltransferase, but plasma total lipid concentration was increased. HSO supplementation had no effect on milk yield, but it increased milk fat and protein contents. HSO supplementation markedly altered milk FA composition, but had no effect on milk cholesterol or vitamin A concentrations. Changes in milk FA composition corresponded to a decrease in saturated de novo synthesized FA (10:0-16:0) and an increase in 4:0, 18:0, and polyunsaturated FA concentrations. Also, HSO supplementation strongly increased cis-9,trans-11-CLA and also trans-18:1 concentrations in milk fat. These findings suggest that HSO can be used to modify milk FA content with a putative positive effect on human health, without adversely affecting goat performance or health, except for a potential hyperlipidemic effect.

“…It is obvious from data of Fig. 1, 2 and 3 that the main factors that affect the animal sexual growth are animal age and body weight with high correlation (r = 0.81) was observed between body weight and progesterone concentration, while the correlation between total blood cholesterol and progesterone concentration was (r = 0.45) in this connection (Bianchi et al, 2014) found a higher concentration of circulating cholesterol is positively correlated to progesterone levels (r = 0.74). …”

This study aimed to investigate effects of inclusion biologically treated rice straw with Trichoderma viride or Trichoderma reesei in ewe-lambs ration on its productive and some physiological response. Thirty crossbred (Rahmany X Romanof) ewe-lambs (three months old and 17±1.13 kg body weight) were assigned randomly to three groups (10 animals each). The first group was fed ration contained 55% concentrate feed mixture and 22.5% clover hay plus 22.5% Untreated Rice Straw (URS), group two and three were fed rations contained rice straw treated with T. reesei (TRSR) or T. viride (TRSV), respectively. No significant differences were observed in nutrients digestibility, Total Digestible Nutrients (TDN), nitrogen retention and nitrogen utilization efficiency among the experimental groups. Treatments did not record differences in TVFA's, ammonia concentration and pH value of rumen liquor at 0, 3 and 6 h post feeding. Also no significant differences were observed among the experimental groups in blood metabolites, while albumin, cholesterol and progesterone concentration increased (p<0.05) as animal age increased. Groups fed TRSV and TRSR recorded lower (p>0.05) values in total gain, average daily gain and worst (p>0.05) feed conversion as DM and CP compared to the control group. It could be concluded that using biologically treated rice straw in ewe-lambs ration had no adverse effects on nutrients digestibility and nitrogen balance as well as physiological response, while insignificantly decreased (p>0.05) growth performance.

“…The current study used 36 lactating Lacaune ewes, two to four years of age, on their second or third lactation, with one or two offspring as previously described (Bianchi et al 2014). Animals were separated into four treatments based on their body weight, age, parity order, number of lambs, and milk production.…”

“…The treatments consisted of diet with 0% (T0), 2% (T2), 4% (T4) and 6% (T6) of protected fat from palm oil. The feed composition was corn silage, corn ground, soybean meal, wheat bran and calcium soap (palm oil), as previously described (Bianchi et al 2014). This protocol was approved by the Animal Ethics Committee of the Universidade Tecnológica Federal do Paraná.…”

“…Several oils can be used as a good source of fatty acids in the form of protected fat to feed ruminants, such as the palm oil (Bianchi et al 2014). This oil is rich in carotenoids, vitamin E and antioxidants (Cesco et al 2013), and presents 50% of SFA on its composition, being 44% of palmitic fatty acid and 5% of stearic fatty acid (C18:0).…”

The aim of this study was to modify the fatty acid profile of yogurt from sheep milk by the inclusion of different concentrations of palm oil into their diet. Thus, thirty-six sheep during lactation were separated in four groups with nine animals each, as described below: the group T0 (0%); the group T2 (inclusion of 2% of palm oil); the group T4 (inclusion of 4% of palm oil) and the group T6 (inclusion of 6% of palm oil). After 60 days of the supplementation, milk samples were collected and yogurt was produced, which was evaluated regarding the concentration of saturated fatty acids (SFA), monounsaturated fatty acids (MFA), and polyunsaturated fatty acids (PFA). A significant reduction (p<0.05) in most SFA and a significant increase (p<0.05) on MFA and PFA was observed in the yogurt of sheep supplemented with 4 and 6% of palm oil. Consequently, it is possible to conclude that palm oil supplementation exerts positive effects on yogurt, since it led to the reduction of undesirable fatty acids and increased fatty acids beneficial to human health.
