Preferred Abstract (Original): 

Effects of oil supplemented diets on growth performance and carcass proportions were studied using 27 male Black goat kids with a body weight (BW) of 19.4 ± 0.41 kg at the beginning of the experiment. Kids were randomly divided into 3 groups of 9, and those in each group were individually fed cereal grain-soybean meal (SBM) based total mixed rations (TMR) with a fixed amount (i.e., 30 g/kg dry matter (DM)) of oil being either: sesame (SES), sunflower (SUN) or soybean (SOY). All TMR were isonitrogenous and iso-metabolizable energy (ME). At the termination of the 105 d feeding study, all kids were slaughtered. Kids fed SES or SOY supplemented diets consumed more (P<0.05) feed (i.e., DM, organic matter, crude protein, neutral detergent fiber) and gained more BW (P<0.05) than those fed the SUN supplemented diet. However, kids fed the SES supplemented diets had a better (P<0.05) feed conversion ratio than kids fed the SUN or SOY diets. Oil type had no effect on carcass components (i.e., loin, legs, shoulder, rack) weights. Liver and kidney fat were heaviest (P<0.05) in kids fed the SES supplemented diet. However, kids fed the SES supplemented diet had less (P<0.05) mesenteric fat and lower (P<0.05) total gastrointestinal tract weights compared to kids fed the SUN or SOY supplemented diets. Eye muscle width and depth and rib eye area were higher (P<0.05) in carcasses of kids fed the SES supplemented diet. Positive effects of SES as a supplemental oil on most responses is encouraging, but more investigation is needed to identify the optimal level of SES in various diets of goat kids.

Preferred Abstract (Original): 

Objective: Effects of oil supplemented diets on muscle lipid profile was studied using 27 Black goat kids. Methods: All kids were male with a body weight of 19.4依0.41 kg at the beginning of the experiment. Kids were randomly divided into 3 groups of 9 kids each. Kids in each group individually received cereal grain-soybean meal (SBM) total mixed rations (TMR) with a fixed amount (30 g/kg DM) of oil being either: sesame (SES) oil, a product of sesame seed crushing, sunflower (SUN) or soybean (SOY) oil. All rations were isonitrogenous and isoenergetic. At the termination of the 105 d feeding study, all kids were slaughtered. Results: Results of the study showed that the SES kids muscles had higher (P<0.05) crude protein content compared to that of kids consuming the SOY or SUN diets, however, tissue fat and cholesterol contents were not affected by type of supplemental oil. Type of oil had no significant effects on both total saturated and unsaturated fatty acids. The addition of SES to the concentrate had no effect on C14:0 and C18:0, but significantly increased (P<0.05) C16:0 compared to diets supplemented with SUN and SOY. The SES supplemented diets resulted in lower (P<0.05) C18:1 cis-11. However, both SES and SOY oils increased (P<0.05) the C18:3 all cis proportion. Linolenic acid (C18:3) proportion lowered (P<0.05) when SUN was included in the diets, which led to a lower C18:2/C18:3 ratio. All types of oils supplemented had similar effect on C18:2 trans-9,12 and C18:2 cis-9,12. In conclusion, supplementation of SES has similar effects as SUN or SOY on most of tested parameters. Results of our study, the first in our region, showed potential advantages of feeding SES supplemented diets to kids in comparison with diets supplemented with SOY or SUN. In addition the lower price of SES makes it a feasible feed choice. Conclusions: Supplementation of SES has similar effects on most of tested parameters. Results of our study, the first in our region, regarding effects on tissue lipid profile of Black kids, showed potential advantages of feeding SES supplemented diets to kids in comparison with diets supplemented with SOY or SUN. In addition the lower price of SES makes it a feasible feed choic.
