“…The addition of fat to the diet did not alter the intake of DM, CP, and neutral detergent fiber compared with the control diet. Similar results were obtained by Rosa et al (2013) in a recent study with young Nellore bulls fed different sources of fat, protected or not from rumen degradation. Diets were formulated with the same amount of protein and with a forage:concentrate ratio of 40:60, with sugarcane as the only roughage.…”

“…The absence of differences (P > 0.05) between the treatments in relation to FLW and DWG is due to the level of EE in the diet in this study, and this fat concentration did not compromise animal performance. However, Rosa et al (2013) in a study in Brazil with young Nellore bulls in a feedlot concluded that the inclusion of vegetable oils, protected or not from rumen degradation, improves performance and carcass characteristics, regardless of the type of fat. DWG in this study was within the expected range.…”

Performance and carcass characteristics of cattle fed lipid sources in the diet

et al. 2016

The aim of this study was to determine the effect of the inclusion of different lipid sources [whole cottonseed (CS) and protected fat in diets containing sugarcane, corn, citrus pulp, CS meal, and urea] on animal performance, hot carcass dressing (HCD), ribeye area (RA), fat thickness (FT), and postmortem pH of the meat of Nellore cattle during finishing. The treatments evaluated were feed with 2.50% CS (control diet, T1 treatment); feed with 11.50% CS (high CS, T2 treatment); and feed with 3.13% CS added of protected lipid (PL) (T3 treatment), all on a DM basis. The forage:concentrate ratio of the diet was 50:50. Thirty-nine intact steers with average initial body weight of 494 kg and 36 months old were confined for 63 d. The addition of lipid sources tested in this study did not affect dry matter intake, crude protein intake, neutral detergent fiber intake, final live weight, average daily weight gain, HCD, RA, FT, and meat pH. It was concluded that the addition of PLs in the diet did not affect weight gain and carcass characteristics.

“…Lipid inclusion in ruminant diets increases the energy density and can result in better performance (Nelson et al, 2004;Rosa et al, 2013). However, fatty acids can reduce ruminal fermentability and potentially affect the performance of the animal.…”

Performance and methane emissions of Nellore steers grazing tropical pasture supplemented with lipid sources

et al. 2016

-The objective of this study was to evaluate the effect of lipid sources on voluntary intake, digestibility, performance, and CH 4 emission of Nellore steers grazing Brachiaria brizantha cv. Xaraés forage in the dry season. Forty-five Nellore steers with average weight of 442±34 kg were alloted into one of the five treatments: without additional fat; with palm oil; with linseed oil; with protected fat; and with whole soybeans. The supplements were provided daily and quantities were adjusted to 1% of body weight and diets were formulated in accordance with the Cornell Net Carbohydrate and Protein System. The experimental design was completely randomized with five treatments and two replications. There were no effects on dry matter, organic matter, and neutral detergent fiber intake with the inclusion of lipids in the diet. The neutral detergent fiber showed decreased digestibility in animals receiving linseed oil and palm oil treatments compared with animals receiving the diet without additional fat. The linseed oil treatment reduced CH 4 emissions by 38% when expressed in mg/d/kg BW and tended to reduce the emission in g/d/kg BW 0.75 . Lipid sources did not affect the weight gain of the animals. The intake and performance of grazing Nellore steers supplemented at 1% body weight with lipid sources were not modified. However, fiber digestibility was reduced with palm or linseed oil addition. Linseed oil reduced enteric CH 4 emissions. Linseed oil has the potential to reduce enteric CH 4 emissions in continuous tropical grazing systems based on B. brizantha grass.

“…Dietary fat is a popular means of increasing the energy density of diet in ruminant nutrition and can influence adipose depots and carcass composition [ 1 – 3 ]. Dietary fat can also be used to modify the fatty acid composition of meat and milk to fulfill the nutritional demands of consumers [ 4 , 5 ].…”

Carcass traits, meat yield and fatty acid composition of adipose tissues and Supraspinatus muscle in goats fed blend of canola oil and palm oil

et al. 2015

BackgroundDietary fats can alter the deposition and distribution of body fats in ruminants. The deposition and distribution of body fat play a vital role in the quality of ruminant carcasses and are of great commercial value since they influence the profitability and consumer acceptability of ruminant meat. The current study examined the effects of dietary blend of 80 % canola oil and 20 % palm oil (BCPO) on carcass characteristics, meat yield and accretion of fatty acid (FA) in subcutaneous, omental, perirenal, and mesentery adipose depots and m. supraspinatus (SS) in goats.MethodsTwenty four Boer crossbred bucks (BW 20.54 ± 0.47 kg) were randomly assigned to diets containing on DM basis 0, 4 and 8 % BCPO, fed for 100 d and harvested.ResultsDiet had no effect (P > 0.05) on slaughter weight, dressing percentage, carcass and non-carcass components, meat yield, color, moisture and carotenoid contents and weight of adipose tissues in goats. The proportion of C18:1n-9 and cis-9 trans-11 CLA in the omental, perirenal and SS was higher (P < 0.05) in goats fed 4 and 8 % BCPO compared with the control goats. Dietary BCPO reduced (P < 0.05) the proportion of C14:0 in the omental, perirenal and mesentery depots, C18:0 in the perirenal depot, C16:0 in the SS and C16:1n-7 in the SS, omental and perirenal tissues. Dietary BCPO enhanced the proportion of C18:1 trans-11 Vaccenic and C18:3n-3 in SS and C20:5n-3 in SS and mesentery depot. No significant changes were found in the FA composition of subcutaneous depot.ConclusionsResults indicate that dietary BCPO can be utilized to alter the FA composition of adipose tissues without detrimental effects on carcass characteristics in goats. Nonetheless, dietary BCPO is not an effective repartitioning agent for body fats in goats.
