There is a growing demand by the modern consumer for meat containing less fat and lower levels of saturated fatty acids, which are considered to increase the risk of coronary heart disease. In southern Italy, the Gentile di Puglia breed is one of the most common on farms, and the light lambs are often consumed. The study evaluates the effect of a diet containing extruded linseed (Linum usitatissimum) on growth performances, carcass traits, and meat quality in Gentile di Puglia light lambs. Thirty-six male lambs are weaned at about 20 days of age, and divided into three groups—each group is either fed a control diet (C), a diet containing 3% extruded linseed (L), or a diet containing 3% extruded linseed and 0.6% oregano (Origanum vulgare) (L + O). The lambs’ growth performances and the slaughtering and dissection data did not differ between groups. Dietary treatments have no significant effect on the quality and chemical composition of Longissimus lumborum (Ll). The mount of linoleic acid in Ll meat is significantly higher in the L group, and this positively affected the total content of n-3 Polyunsaturated Fatty Acid, as well as the n-6/n-3 ratio. The good results obtained concerning the sensory traits meet the requirements of the market’s consumer.

To evaluate the influence of linseed and oregano dietary supplementation in Jonica kids, we carried out a trial that involved 30 male Jonica kids 20 days old, divided into three groups of ten animals. Each group was ascribed to one of the following dietary treatments: (C) group control fed without any supplement; (L) group fed control feed containing 3% extruded linseed (Linum usitatissimum); and (L + O) group fed control diet with 0.6% dried oregano (Origanum vulgare) and 3% extruded linseed. The kids were slaughtered at 60 days of age; carcass and cut yields were performed. The Longissimus lumborum muscle was separated to determinate physical, chemical, and fatty acid composition. Supplementation of kids’ diet with oregano did not show effects on performances in vivo and post mortem. Extruded linseed and oregano feed made commercial cuts of kids carcasses less fat (6.75% vs. 10.92% for leg; 4.82% vs. 7.73% for loin), whereas only the extruded linseed diet made the meat fatter (20.11% vs. 19.75%) and more proteic than the commercial pellet (20.11% vs. 19.75%). The use of oregano reduces the meat oxidation compared with the only use of linseed in kids’ diet (0.298 vs. 0.645). The healthy and beneficial effect of linseed in the diet is observed in meat with the lower value of n-6/n-3 ratio (4.57 vs. 8.60) and atherogenic (0.60 vs. 0.77) and thrombogenic (1.36 vs. 1.61) indices. Linseed diet enrich kids meat with healthy fatty acids that are easier to oxidize; instead, the addition of oregano, thanks to its antioxidant properties, allows a longer conservation and a more profitable marketing.

The aim of this trial was to compare the influence of supplementing diets with extruded linseed and oregano on growth parameters and meat qualitative traits in Grigia di Potenza breed suckling kids. Twenty-four male kids, exclusively fed milk from their dams, were assigned to the following diets: C) group control fed without any supplement; L) group fed control feed containing 3% extruded linseed (Linum usitatissimum L.); and LO) group fed control diet with 0.6% dried oregano (Origanum vulgare) and 3% extruded linseed. Growth performance as well as slaughtering traits and meat cuts of kids were not significantly influenced (P > 0.05) by dietary treatments. Conversely, kids in linseed group reported the lower (P < 0.05) percentage of dissectible fat in leg and loin. The meat from Longissimus lumborum and Semimembranosus muscles of kids in linseed diet had the lowest (P < 0.05) cooking loss percentage, whereas the proximate chemical composition of both meat muscles did not vary among treatments (P > 0.05). The experimental diets partially modulated the kid meat fatty acid composition in both muscles, where feeding linseed and oregano improved (P < 0.05) the content of DPA and reduced MUFA. Based on the current findings, it can be concluded that linseed and oregano supplementation can be used in goat diet as no significant detrimental effects on productive performance and meat quality of suckling kids were observed. © 2021 Friends Science Publishers

The effects of feeding concentrate diet containing crude glycerin supplementation and castration on carcass composition and meat quality of Thai Native x Anglo-Nubian (TN-AN) goats were investigated. Twenty TN-AN goats at the age of 12 months old with 24.75±1.33 kg initial live weight were allotted into a 2x2 factorial arrangement in completely randomized design when factor A was assigned for sexes (intact and castrated male) and factor B was assigned for 2 types of concentrate diet (control diet and diet supplemented with 10 % crude glycerin). Goats were intensively raised in individual pens with ad libitum water and Atratum grass (Paspalum atratum), while 2 % of concentrate diets was provided. After 90 days of feeding, 3 goats from each treatment combination were randomly sampled and sacrificed for further examination. From the study, castrated male goats had significantly higher slaughter and carcass weight, carcass fat percentage and chemical fat percentage than those of the intact males (P < 0.01). In addition, muscle from castrated male goats was more tender and lighter in color as compared with intact male goats (P < 0.01). Goats receiving a diet with extra glycerin had significantly higher weight at slaughter, warm carcass weight, carcass fat, and chemical fat percentages than those on the control diet. Therefore, it could be concluded that feeding goats with a diet of 10 % supplementary glycerin and castration could lead to better slaughter and warm weight, whereas a higher fat content in the carcass and muscle are observed.

The effects of sex and slaughter age on growth, feed intake, carcass composition and meat quality attributes of musculus longissimus lumborum were investigated in Charolais &times; Simmental bulls (n = 12) and heifers (n = 12) reared and finished under identical management conditions. The animals entered the experiment at similar age (251 days) and were slaughtered at 14 or 18 months of age. Bulls gained more rapidly (P &nbsp;&lt; 0.001), consumed more dry matter daily (P &lt; 0.05), and had a higher killing-out proportion (P&nbsp;&lt;&nbsp;0.05). The sex &times; slaughter age interaction was significant (P &lt; 0.01) for feed conversion ratio, which deteriorated markedly more in heifers than in bulls as slaughter age increased. Bulls produced leaner carcasses with a higher proportion of total meat (P &lt; 0.001). While bulls contributed to high-priced meat by a higher proportion of meat from the shoulder (P &lt; 0.01), heifers had higher proportions of meat from the rump and loin (P&nbsp;&lt; 0.05). Older animals were generally fatter and their carcasses contained lower proportions of high-priced meat (P&nbsp;&lt; 0.01) and bones (P &lt; 0.05). Bulls exhibited lower contents of dry matter (P &lt;&nbsp;0.001), protein (P &lt; 0.05) and intramuscular fat (P &lt; 0.001), and a higher content of collagen (P &lt; 0.001) in musculus longissimus lumborum than hei-fers. The meat from heifers was assessed by the sensory panel as more tender and, when aged for 11&nbsp;days, more acceptable than the meat from bulls. Older animals obtained higher scores for beef flavour intensity (P &lt; 0.01), tenderness (P &lt; 0.001), juiciness (P &lt; 0.05), and overall acceptance (P &lt; 0.001). &nbsp;

Dietary Oil

Diets high in fat have been used in the production of pigs in the growing and finishing stages for the improvement of meat production and quality parameters. Therefore, this study was conducted to evaluate the effect of adding different oil sources to the diet of immunocastrated male pigs on meat quality characteristics. Ninety-six pigs were randomly allotted to one of four dietary treatments, with six replicate pens per treatment and four pigs per pen. Dietary treatments consisted of diets supplemented with 1.5% soybean oil (SO; control) or 3% oil from SO, canola oil (CO), or fish oil (FO). After 98 days on trial, 18 pigs per treatment (n = 72) were slaughtered and samples of the Longissimus dorsi muscle were taken for Warner-Bratzler shear force and color (L*, a*, and b*) measurements. Loins from pigs fed diets containing either 3% SO or CO had decreased Warner-Bratzler shear force (P = 0.04) than those from pigs fed the control diet. Dietary treatments had no effect on color components of fresh loin. These results indicate that feeding 3% SO or CO increased pork tenderness, without compromising color meat of immunocastrated male pigs.

Abstract This study was carried out to evaluate the best inclusion level and the effects of mesquite pod (Prosopis juliflora) meal on carcass characteristics and meat quality for lambs finished in pasture. Forty male, non-castrated, crossbred Santa Inês lambs, with an initial body weight (24.2 ± 3.1 kg), and approximately 120-days old. The animals were kept in a total area of ​​4 ha, divided in 4 paddocks of 0.62 ha each (10 animals/paddocks), on pastures of Massai (Panicum maximum cv. massai) with drinkers and feeders during the finishing phase. Dietary treatments based on levels of corn ground replacement for mesquite pod meal included: CON – Without mesquite pod meal; MPM25 – 250 g/kg of mesquite pod meal; MPM50 – 500 g/kg of mesquite pod meal; and MPM75 – 750 g/kg of mesquite pod meal. No treatment effects were detected (P> 0.05) for carcass measures, carcass characteristics, chemical composition of longissimus thoracis muscle, tissue composition, and lipid oxidation. Lamb meat color values, such as lightness (L*) and yellowness (b*) were not affected (P> 0.05) by mesquite pod meal replacement on the diets, whereas for redness (a*), HUE, and crhoma were influenced (P< 0.05). Palmitic acid had a quadratic effect, while oleic acid, eicosatrienoic acid, saturated fatty acids, monounsaturated fatty acids, and PUFA:SFA had a linear course (P< 0.05). In conclusion the mesquite pod meal can be used as an energy feed source up to 750 g/kg of dry matter in the diet, without changing the carcass characteristics and meat quality of lambs finished in pasture.

SUMMARYTwenty-four Friesian steers, initially 5 months of age, were involved in a 2 × 2 factorial experiment which spanned grazing and silage feeding periods of 22 weeks' duration. In the first period, cattle were stocked at a uniformly high density, with half of the group being fed 1·25 kg/head per day of supplementary barley. In the second period, the cattle were subdivided into four groups and fed varying levels of barley with silage. Finally all the animals received 3·65 kg/head per day of barley. Replicates of the four treatments were slaughtered at random after 5 to 11 weeks on this treatment. Whilst supplementary cereal feeding significantly increased the live-weight gains of steers at grass by 11%, this live-weight advantage was offset by their slower gains in the final weeks before slaughter. Feeding cereals to grazing cattle had little effect on carcass composition or the proportions of carcass joints, but their beef was considered, by a tasting panel, to be more tender than the meat from the control steers.Increasing the level of barley fed with silage only increased live-weight gains by 2%, and had little effect on carcass or meat quality.

Abstract The study was conducted to assess the effect of black pepper (BP) supplementation on the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs. A total of 180 crossbred [(Landrace × Yorkshire) × Duroc] finishing pigs with average initial body weight (BW) of 53.72 ± 1.42 kg were used in 10-week trial and allotted to 6 dietary treatments (6 replications pens/treatment with 5 pigs per pen). The dietary treatments were: CON (basal diet), TRT1- CON + 0.025% BP, TRT2- CON + 0.05% BP, TRT3- CON + 0.1% BP, TRT4- CON + 0.2% BP, TRT5- CON + 0.4% BP. A linear increase (P = 0.0380, 0.0061) in body weight gain (BWG) and average daily gain (ADG) were observed respectively, during the overall trial in pigs fed BP supplemented diet compared to control. The dietary supplementation of BP showed a linear increase (P=0.0065) in gain and feed ratio (G: F) at week 10. However, there were no significant results observed on average daily feed intake (ADFI) during the overall experiment. The total tract digestibility of dry matter (DM) was linearly improved (P=0.0531) in BP treatment groups compared to control. In addition, BP diet supplementation had linearly increased fecal Lactobacillus counts (P=0.0482) and decreased E. coli counts (P=0.0306) in pigs at week 10. Furthermore, NH3, methyl mercaptans, and acetic acid was linearly decreased (P=0.0227, 0.0555,0.0541) in pigs fed BP supplementation compare to control. The inclusion of BP supplementation in pigs diet had linearly increased (P=0.0146) the backfat thickness at week 10. Thus, we concluded that BP supplementation had positively enhanced the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs.
