Effect of whole cottonseed v. sunflower seed on the fatty acid profile of subcutaneous fat, longissimus dorsi and blood of Thai Native and Holstein bulls

Abstract

In a 2 × 2 factorial design, 12 Thai Native and 12 Holstein bulls were fed ad libitum a total mixed ration (20 : 80; roughage : concentrate) with whole cottonseed (WCS) or sunflower seed (SFS) as oilseed sources. The rations contained 7% crude fat and were fed for 90 days. Plasma was taken at three times during the experiment, and at slaughter the longissimus dorsi and subcutaneous fat were sampled for fatty acid analysis. Ration did not affect rumen fermentation parameters. The plasma fatty acid profile was not affected by ration. In subcutaneous fat, a ration × breed interaction for the saturated fatty acid (SFA) and c9t11 CLA proportions was observed, resulting from larger differences between the rations in Thai Native compared with Holstein bulls. The WCS ration resulted in higher proportions of SFA and lower proportions of monounsaturated fatty acids and c9,t11 CLA compared with the SFS ration ( P < 0.01). In the intramuscular fat, the WCS ration was also associated with a lower c9t11 CLA proportion ( P < 0.01) and higher SFA proportion ( P < 0.05). The intramuscular proportion of polyunsaturated acids was higher and the proportion of SFA was lower in Thai Native compared with Holstein bulls ( P < 0.05), irrespective of ration.

Influence of bagasse versus rice straw with oil sources in a total mixed ration on feed intake, digestibility and blood chemistry of crossbred Thai Native x American Brahman cattle

“…Additionally, Wachirapakorn et al (2016) reported that cows fed ground corn cobs (33%) and rice straw (7%) in TMR, NDF digestibility was 63.40% and 52.60% respectively. However, for EE digestibility this experiment was approximately 86.36% lower than Polviset et al (2015) who suggested that 97.50% EE digestibility in Thai native bulls fed with sunflower seed. It might be reasoned that oil seeds may not negatively affect nutrients' digestibility.…”

Effect of Supplementation of Several Edible Plant Oils on Nutrient Utilization and Blood Profile of Beef Cattle

“…Moreover, Kongmun et al (2011) suggestted that feeding of 7% coconut oil and 7% coconut oil plus garlic powder in swamp buffalo did not affect the DM, OM and ADF digestibility. Feeding sunflower seed and whole cotton seed in TMR contained 7% crude fat of Thai Native and Holstein bulls did not neither affect the digestibility of DM, OM, NDF and ADF by breed nor by different oilseed sources that oil seeds are less toxic than purified oils (Polviset et al, 2015). Additionally, adding soybean oil is harmful to microorganisms in the rumen and the fiber digestibility (Thanha et al, 2018).…”

Whole cottonseed, vitamin E and finishing period affect the fatty acid profile and sensory traits of meat products from Nellore cattle

“…There are some studies that investigated the addition of whole cottonseed (Costa et al, 2013;Polviset et al, 2015) and vitamin E in cattle diets (Machado Neto et al, 2014), however there are no studies that associated these ingredients with different lengths of finishing period affecting meat sensory traits and FA profile. To this end, this study evaluated how the addition of 30% DM whole cottonseed and 500 IU vitamin E in diets fed to Nellore bulls confined during 83, 104, and 111 days affected beef FA profile, and beef and hamburger sensory traits.…”
