SUMMARY The objective of this study was to evaluate the performance, carcass, meat quality, fatty acid profile and liver alterations of cattle supplemented with cottonseed feedlot. It used 100 Nelore cattle, being divided into two groups of 50 animals, which received a cottonseed (CS) in grain form by the diet in the proportion of 15% and the other group was provided with control diet without CS in the feedlot for 88 days. The diets were isoprotein and isoenergetic and concentrate:roughage ratio of 60:40. The animals were slaughter in the end of experimental time and the collection of liver samples for histological analysis. After cooling 24 hours at ± 1°C were conducted evaluation of carcass and major cuts, final pH and collected muscle samples longissimus to carry out the physicochemical analyzes (Color, Cooking Loss, Pigments and Shear Force), chemical composition, fatty acid profile and oxidation. The inclusion of CS in the diet provided animals with higher slaughter weight, daily weight gain, Hindquarter, however, the animals showed reduced carcass yield, forequarter weight and Thin flank, without changing the parameters as rib-eye area and backfat thickness. There was an increase of the yellow values (b*) and moisture with the final pH reduction. There was no influence of the use of cottonseed in relation to histological parameters evaluated in the liver. The cottonseed in the feeding feedlot cattle promoted improvement in animal performance, despite the reduction of the forequarter weight, with appropriate aspects of meat quality, fatty acid profile and conservation.

The aim of this study was to evaluate the effects of adding conjugated linoleic acid (CLA) to boar diets on semen producion and characteristics, the fatty acid profile of spermatozoa, and on testicle and boar carcass parameters. Ten lean-type terminal-line (Yorkshire x Landrace x Petrain) adult boars were randomly assigned to one of two treatments: (1) a control diet and (2) the same diet with 1% CLA. The research was conducted in Mexico, and the animals were exposed to ambient temperatures betwen 13.5 and 26.3 °C. Boars were ejaculated twice per week a 12-week period to examine semen production and characteristics. The results suggest that supplementation of boar diets with CLA did not affect the spermatozoa fatty acid profile, semen volume, sperm concetration, viability, or motility, nor did it cause abnormal sperm morphology. Compared to controls, boar fed a CLA diet had a higher seminal pH and increased backfat thickness. In summary, this study indicates that CLA addition in boar diet does not change the semen characteristics of fatty acid profile of spermatozoa; however, it increases backfat thickness in sexually mature boars.

This study was conducted to evaluate the effects of including two types of crude glycerin (CG) in feed on plasma parameters, quantitative and qualitative carcass characteristics, and the fatty acid profile of the Longissimus dorsi pig muscle. Sixty-three commercial line pigs were used, with an average weight of 30.53 ± 1.59 to 59.55 ± 4.27 kg in the growing phase and 60.35 ± 2.25 to 89.91 ± 5.23 kg in the finishing phase. The pigs’ diet included two sources of CG (vegetable and mixed) at four inclusion levels (3%, 6%, 9% and 12%). One CG was derived from soybean oil (VCG) and the other from 80% animal fat + 20% soybean oil (MCG). The control diet contained 0% glycerin. Blood samples were collected at the beginning, middle and final phases of the trial. In addition, at the end of the finishing phase, the animals were fasted for 12 h and then sacrificed to measure the quantitative and qualitative carcass characteristics and the fatty acid profile of the Longissimus dorsi. The results indicate that in both phases there was a quadratic effect on plasma triglycerides. There was no effect on carcass parameters. A quadratic behaviour for pH24 h was obtained, with the lowest value attained at 1.05% CG inclusion. There was an interaction between the type of glycerin and the inclusion level in the diets for polyunsaturated fatty acids. VCG and MCG can be used at up to 12% inclusion because they cause no negative effects on carcass characteristics and pig meat quality.

ABSTRACT The addition of different oil blends in the feed of finishing pigs was evaluated. Twenty-four castrated male finishing pigs were used in a randomized block design containing four treatments and six replicates. The treatments consisted of: Reference ration (RR) - 100% soybean oil feed; and the combination of the different oils: Blend1 - 50.0% soybean oil (SO), 25.0% flaxseed oil (FO), 12.5% olive oil (OO) and 12.5% canola oil (CO); Blend2 - 25.0% SO, 50.0% FO, 12.5% OO and 12.5% CO; and Blend3 - 25.0% SO, 12.5% FO, 12.5% OO and 50.0% CO. The performance, quantitative and qualitative carcass parameters, fatty acids profile and economic feasibility of the diets were evaluated. The use of blends in the diets did not influence the performance or carcass quality, but increased marbling and carcass yield. The fatty acid profile of the loin presented greater amounts of stearic acid in Blend3 and higher percentage of unsaturated fatty acids in animals fed with Blend1. The fatty tissue presented greater amounts of myristic acid in Blend1 and oleic acid in Blend3. The reference ration was the most economic. The Blends did not affect performance or carcass characteristics and improved the fatty acid profile.

Carcass parameters, meat quality, fatty acid profile, and amino acid composition of Simmental bulls fed a diet based on various forage silages (VS) compared with the one based on only corn silage (CS) were investigated. A total of thirty male Simmental (440.5 ± 11.5 kg) was selected and assigned randomly divided into two treatments. All animals were fed twice daily (0700 and 1700 h) and water was supplied ad libitum, feed considering 5 to 10% refusals. The period of 207 days fattening trial was divided into three stages as P1 (1 to 64 days), P2 (65 to 130 days), P3 (131 to 207 days). Six beef cattle were slaughtered from each group at the end of the experiment. Substituting CS with VS in the finishing diet did not have a significant effect on slaughter performance, nutrient content, fatty acids, and amino acids profile (P > 0.05). However, the intramuscular fat and connective tissue content of the VS diet was lower compared with the CS diet (P < 0.05). Also, beef cattle fed VS diet could improve eye muscle area, increase histidine content and diameter of muscle fiber. In conclusion, substituting corn silage with various forage silages in the diet of beef cattle could potentially reduce the negative effect under the studied conditions. © 2021 Friends Science Publishers
