“…Cis-9, trans-11 CLA is the most common CLA isomer, although, the presense of other CLA isomers and their probaply concentrations vary according to rumen condition (Matsushita et al, 2007). Results of the cis-9, trans-11 CLA agrees with AbuGazaleh et al (2002) who found that feeding SBO to lactating dairy cows has increased milk cis-9, trans-11 CLA, and Zhang et al (2006) who revealed that ewes fed SF seed increased total and cis-9, trans-11 CLA concentration in their milk.…”

“…Results of the cis-9, trans-11 CLA agrees with AbuGazaleh et al (2002) who found that feeding SBO to lactating dairy cows has increased milk cis-9, trans-11 CLA, and Zhang et al (2006) who revealed that ewes fed SF seed increased total and cis-9, trans-11 CLA concentration in their milk. Mir et al (1999) suggested that the reason behind this increase in CLA milk concentration was due to the precursors of CLA, C18:2 and C18:3, found in oil of C18:2 which present in higher concentration in SBO than in SFO (Zhang et al, 2006;Matsushita et al, 2007). The amount of CLA and type of CLA isomers in ruminants' milk fat produced as a result of feeding supplemental fat varies to a large extent depending on the ruminal conditions and the availability of the oils to the rumen microbes (Loor and Herbein, 2003), as well as to animal characteristics such as species, breed, lactation stage and genetic potential (Chilliard et al, 2003).…”

“…Likewise, Loor et al (2002) found that feeding canola oil to lactating Holstein cows increased the concentration of CLA in the milk. Supplementing goat diet with 3% different vegetable oils (canola, sunflower or soyabean oil) showed an increase in CLA concentration in Saanen goat milk (Matsushita et al, 2007).…”

A study was conducted to determine the effect of feeding soyabean or sunflower oil to lactating Shami goats on milk production, composition and fatty acid profile. Goats (n=125), 2 to 4 years of age and 55 to 60 kg liveweight, were randomly assigned to 5 treatment groups (25 each) in a completely randomized design. Diets were: a control ration (C), control supplemented with 3% soyabean oil (3%SBO), control supplemented with 5%SBO, control supplemented with 3% sunflower oil (3%SFO), and a control supplemented with 5%SFO. Variables measured were milk production, milk composition, dry matter intake, body weight, weaning weight of kids, blood metabolites, and milk and blood fatty acid profiles. Daily milk production was reduced (P<0.05) in most treatments. Fat and protein yields were maximum (P<0.05) at 3%SBO while energy corrected milk was highest (P<0.05) for the 3%SBO. Feed intake was least (P<0.05) for the 3%SFO group and feed to milk ratio was highest (P<0.05) for the 3% SBO group. Values for the serum cholesterol were highest (P<0.05) for the SBO kids. Meanwhile, triglycerides were reduced (P<0.05) following oil treatment with the lowest (P<0.05) value in the serum of the 5%SBO kids. Total conjugated linoliec acid (CLA) content in milk was mostly increased (P<0.05) for oil treated goats. In the blood of kids, total CLA was maximum (P<0.05) for kids of the 5%SFO group.Results indicate that supplementing lactating goat diet with either oils did not improve milk production, milk composition, or growth rate and weaning weight of their kids, but improved their energy corrected milk and CLA content. However, only SBO increased cholesterol level in the blood in kids.

“…The major CLA isomer in ruminant milk fat, cis-9, trans-11, was reported to present anticarcinogenic and anti-atherogenic properties in animal experiments, and its concentration in goat milk might be increased with vegetal oil supplementation of animal diets (Bernard, Shingfield, Rouel, Ferlay, & Chilliard, 2009;Matsushita et al, 2007). Nutritional strategies to increase milk CLA content also result in other positive changes in the composition of milk fat, reducing the content of saturated fatty acids and increasing the proportion of monounsaturated and polyunsaturated fatty acids.…”

“…High levels of long chain polyunsaturated FA lipids increase trans-vaccenic (18:1 t11 ; TVA) and conjugated linoleic acids (18:2 c9 t11 ; CLA) in milk, which are considered functional for their positive effects on human health (Druart et al, 2014;Lim et al, 2014;Yang et al, 2015). Ruminal biohydrogenation of oils rich in linoleic acid (18:2 c9 c12 ) such as corn oil produces higher concentrations of TVA than oils rich in linolenic acid (18:3 c9 c12 c15 ) in vitro and in vivo (Matsushita et al, 2007;Castillo et al, 2012). In vivo, higher ruminal proportions of TVA have been associated with higher CLA and TVA milk proportions (Harvatine and Bauman, 2006).…”

Supplementation with corn oil and palm kernel oil to grazing cows: ruminal fermentation, milk yield, and fatty acid profile

-The effect of supplementation with corn oil (CO) and its mixture with palm kernel oil (CO:PKO 75:25) to grazing cows on ruminal fermentation, milk yield, and its fatty acid (FA) profile was evaluated. The treatments were: one control treatment (C) without oil and two treatments with 720 g d −1 /cow of CO or CO:PKO (ether extract: 22.7 g kg −1 for control treatment, 66 g kg −1 for CO, and 65 g kg −1 for CO:PKO). Six multiparous Holstein cows (6.3±1.8 yr, 597±11.5 kg body weight (BW), 160±29 d in milk; mean ± standard deviation) were assigned to a double 3 × 3 × 3 Latin square design. Cows grazed (3 kg DM/100 kg BW) a Cenchrus clandestinus (previously Pennisetum clandestinum) pasture and were supplemented with 0.9 kg d −1 DM corn silage, 4.2 kg d −1 DM concentrate, and 9 g Cr 2 O 3 . The mixture of concentrate and oils was offered twice a day. The addition of oils increased milk yield (kg d −1 ) (C: 21.4, CO: 23.6, CO:PKO: 23.9) and milk fat concentration (g kg milk −1 ) (C: 31.5, CO: 34.0, CO:PKO: 34.0). Compared with control, conjugated linoleic acid (18:2 c9 t11 CLA) proportion (g 100 g −1 FA) in milk fat was higher for oil treatments (C: 0.68, CO: 1.56, CO:PKO: 1.01). Voluntary intake and digestibility were not different among treatments. The molar ratio of acetate, propionate, and butyrate was not different among treatments, but the molar concentration of volatile fatty acids (VFA) was lower for CO and CO:PKO, resulting in a lower estimated methane (CH 4 ) production (mL/100 mol VFA) for CO and CO:PKO treatments. Supplementing CO and CO:PKO to grazing dairy cows increases milk yield without affecting voluntary intake or diet digestibility. The proportion of conjugated linoleic acid increases more for CO than for CO:PKO.
