“…Interestingly, ether extract percentage of muscle was seen to decrease linearly with the increase in the amount of CS in the diet of cattle in the feedlot. These results are strongly indicative of the fact that LP is more efficient in passing through the rumen so as to be absorbed in the small intestine and subsequently incorporated into the muscle (Putrino, 2006;Lima et al, 2016).…”

The use of oil supplies in feed increases the energy density of the diet and has the potential to enhance both animal performance and meat quality. Whole cottonseed is an oilseed that has a high concentration of oil and is especially rich in unsaturated fatty acids such as linoleic acid. Whole cottonseed is considered as an excellent alternative addition to ruminant feed. Protected lipids are composed of industry-based fatty acids. In the feedlot, protected lipids are used in conjunction with calcium and, in certain cases, their addition has been seen to augment meat quality in terms of essential fatty acid concentrations. This review discusses and debates the use of the whole cottonseed as well as protected lipids (calcium salts of fatty acids) as dietary additives to ruminant feed and diet, and also its impact on meat quality. The whole cottonseed and or protected lipids are viable feedlot alternatives for use in feedlot when it is desired to reduce the amount of starch in animal diet without compromising the performance. The addition of the whole cottonseed or protected lipid in diet is not affect pH values in meat. The whole cottonseed does not contribute to the improvement of tenderness of the meat. The proportion mean of Desirable fatty acids in meat in the comparative study were: as pentadecanoic acid (C15:1 = 0.29%), palmitoleic acid (C16:1 = 4.26%), heptadecanoic acid (C17:1 = 0.07%), oleic acid (C18:1n9c = 37.32%), γ-linolenic acid (0.94%) and α-linolenic acid (1.04%), elaidic acid (C18:1n9t = 0.50%), eicosatrienoic acid (C20:3n3 = 0.03%), eicosapentaenoic acid (C20:5n3 = 0.04%), erucic acid (C22:1n9 = 0.89%), docosadienoic acid (C22:2 = 0.04%) and stearic acid (C18:0 = 21.53%). The addition the cottonseed or protected lipid in diet does not affect fatty acids profiles the desirable fatty acids in meat.

“…Increased particle passage rate may be beneficial for HLHFP when considering the high ether extract content and the potential negative effect of lipids on ruminal fermentation. That said, there is a debate whether lipid sources positively or negatively affect performance of cattle fed finishing diets (Górka et al, 2013;Lima et al, 2016). Some studies have indicated a negative consequence of lipids on fiber digestion (Jenkins, 1993;Hess et al, 2008) whereas others have shown no effect (Kucuk et al, 2004), particularly when dietary ether extract content is less than 6% (Hess et al, 2008).…”

The objective of this study was to determine the effect of dietary energy substrate and days on feed on apparent total tract digestibility, ruminal fermentation, short-chain fatty acid (SCFA) absorption, plasma glucose and acetate clearance rates, and insulin responsiveness. Eight ruminally cannulated, crossbred growing heifers were randomly allocated to 1 of 2 dietary treatments. The control (CON) diet consisted of 75.2% barley grain, 9.8% canola meal, 9% mineral and vitamin supplement, and 6% barley silage (DM basis). To evaluate the effect of energy source, a high-lipid, high-fiber byproduct pellet (HLHFP) was included in the diet by replacing 55% of the barley grain and 100% of canola meal. The study consisted of 4 consecutive 40-d periods (P1 to P4), with data and sample collection occurring in the last 12 d of each period. Dry matter intake tended ( = 0.10) to decrease by period and HLHFP-fed heifers tended to eat less ( = 0.09). The ADG of the CON was greater than that of the HLHFP during P1 and P4 (treatment × period, = 0.02). Heifers fed HLHFP tended to have greater mean ruminal pH (6.10 vs. 5.96; = 0.07) than heifers fed the CON, but pH was not affected by period. The CON heifers had a greater digestibility for DM, OM, CP, and NDF ( ≤ 0.03), and the digestibility for DM and OM linearly increased ( = 0.01) and for CP, NDF, and starch quadratically increased ( ≤ 0.04) with advancing period. Total SCFA concentration in the rumen was greater ( < 0.01) for the CON than for the HLHFP (141.6 vs. 128.1 m). The molar proportion of acetate and isobutyrate linearly increased and butyrate and valerate linearly decreased ( ≤ 0.05) with advancing periods. The rate of valerate absorption tended to increase (linear, = 0.06) and the ruminal liquid passage rate tended to decrease (linear, = 0.08) with advancing period. The arterial clearance rate of acetate tended to quadratically increase ( = 0.06) with period, whereas the clearance rate of glucose was not affected by treatment or period. Both fasting plasma insulin and the area under the insulin curve in response to glucose infusion linearly increased ( = 0.04) with period. These data suggest that partially replacing barley grain with HLHFP negatively affects total tract digestibility and performance. Moreover, with advancing days on feed, digestibility and insulin resistance increases without changes in ruminal pH and plasma metabolite clearance rates.

“…Many experimental results indicated that animals with negative RFI tend to have adequate subcutaneous fat thickness without the risk of having a carcass with poor back fat thickness, which could devalue the price of meat in the market. The cover fat prevents cold shortening of the carcass during the refrigeration process in the cold chamber in slaughterhouse [9,10]. Negative RFI cattle tend to have leaner and less marbled carcasses (intramuscular fat).…”

Measures such as residual feed intake (RFI) have been increasingly considered to select cattle with superior feed efficiency, as it is a characteristic of feed efficiency calculated as the difference between observed intake and estimated intake considering metabolic weight and the weight gain. Estimated feed intake is obtained through the multiple regression equation of observed consumption on metabolic mean live weight and weight gain. The standard was shared among animals into one herd selected for low RFI (high efficiency) and compared to the one selected for high RFI (low efficiency). There was no correlated response in weight per year and in weight gain, and the effectiveness of low RFI selection in reducing feed costs was proven without affecting production. However, selection of animals with negative RFI is not done by selecting animals directly according to the size of the viscera, rather it is done indirectly, that is, when selecting the most efficient animals and normally these animals already have the smallest viscera size. The RFI is a trait that presents genetic variability, selectable to improve and has moderate heritability, between 0.30 and 0.35. The RFI is important because it reduces the direct economic impacts of reduced feed intake, as well as the effects of environmental impact on reducing methane emissions from enteric fermentation of ruminants.
