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.

SUMMARYTwo experiments concerning the effects, on the carcass and meat characteristics of 18-months-old Friesian steers, of variation in grazing intensity and the level of barley feeding with silage are reported.Groups of 12 steers were grazed at different intensities over 5-month grazing periods, such that live-weight differences of 38 kg and 16 kg were recorded at housing. No compensatory growth was recorded during the subsequent winter feeding period.Whilst the grazing treatments had little effect on carcass or meat quality, higher levels of barley feeding with silage over the winter period (710 v. 410 kg/steer) had significant effects on live-weight gain, and increased carcass weight by 21 kg at slaughter. The higher yield of carcass weight was reflected in significant differences in carcass composition, joint proportions and retail cut-out value. Sixty per cent of the carcass weight difference was removed as trim fat. Differences in carcass fatness were not associated with any differences in eating quality.

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.

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.

Daily Gain

The degree to which growth patterns are modified after a period of food restriction affects the compositional changes of the carcasses(Carstens et al., 1992), furthermore, the growth rate has a direct effect on the physical properties of meat (Fishell et al., 1985). The objective of this experiment was to evaluate the effects of a severe food restriction at a early stage of maturity on the slaughter characteristics and meat quality of Belgian Blue bulls.Twelve Belgian Blue bulls (dual purpose type) weighing 233 kg were offered two different planes of nutrition during the growing period. Six bulls (Group-) received a restricted diet so that their average daily gain was 0.34 kg/d (Group+) during 202 days. By contrast six other bulls were given a more conventional growing diet and their average daily gain was 1.13 kg/d. Both Groups were fattened with similar diet and slaughtered when the live weight was close to 600 kg. Carcass weight was measured and killing-out proportion calculated, the composition of the carcass was estimated after dissection of ribs 7, 8, 9 removed 48 h post-mortem.

Abstract. The aim of this observational study (field experiment) was to evaluate carcass composition and meat quality of male suckling buffalo calves. The animals were born between June and September 2011 and were kept on natural pasture in a cow/calf herd. From the end of November 2011, the suckling calves were fed only roughage as feed supplement in a feedlot until slaughter. For a generalised characterisation, the basic statistics of 18 male calves were calculated. The animals were slaughtered at an average live weight of 196.0 kg. Growth, live weight development and most carcass traits varied substantially between individual calves. The 12th rib muscle composition measured by computer tomography indicated comparable meat contents as evaluated by manual dissection of the carcass. Meat quality parameters (pH and colour) and the nutrient composition (protein, fat, ash) of longissimus muscle samples of calves were relatively similar. The intramuscular fat content of longissimus muscle was low, but shows a high variation between 0.3–1.1 %.

This study evaluated the effects of different energy sources, as corn substitutes, on the carcass characteristics and meat quality of lambs. Twenty-four intact ram lambs were identified, weighed, and assigned to one of four dietary treatments: corn, citrus pulp, rice bran, and soybean hulls. The ram lambs were confined in feedlots, and when they reached 30 kg of live weight, they were slaughtered. A  completelyrandomized design with different replicates was used for the analysis, along with the Tukey-5% test. For hot and cold carcass weight, rice bran produced lower values than the other dietary treatments. For the red color content of the meat, citrus pulp presented superior values when compared to corn, whereas meat and fat color, loin eye area, and objective tenderness did not differ between treatments. Different energetic sources used to replace corn in ram lambs finishing diets did not affect the proximate composition and quality of the meat. Highlights:  • Addition of rice bran to the lambs' diet resulted in lower hot and cold carcass weight.• Animals fed soybean hulls presented the highest carcass compactness index values.• Rice bran extended the feedlot period of lambs in 59.33 days, been longer than the others energies sources.• Corn, rice bran, citrus pulp and soybean hulls did not change the quality of meat but the inclusion of rice bran should be carefully evaluated.

This study was conducted to determine the effect of Ocimum gratissimum leaf meal supplementation on the performance, carcass characteristics and meat quality of broiler chicken. One hundred and fifty day old Abhor Acre strains of broiler birds were assigned to five dietary treatments with thirty birds per treatment in a completely randomized design. Ocimum gratissimum leaf meal at 0g, 100g, 200g, 300g and 400g per 100kg of feed was added to the diets. The experiment lasted for seven weeks. Data on feed intake, weight gain and feed conversion ratio were collected. Two birds per replicate were randomly selected, weighed, slaughtered and properly dressed for carcass parameters such as live weight, plucked weight, dressing percentage, head, neck, wing weight, thigh weight, drumstick, organ weight and sensory evaluation was carried out. The result of the performance characteristics showed that there were significant differences (p

Price Negotiation

Abstract Until the introduction of SEUROP system, price negotiation between pig producers and slaughterhouses was based on two subjective criteria: animal weight and visual inspection of the quality of pigs. To ensure producers a fair payment, European Union created the possibility of binding the price on two objective factors: carcass weight and carcass composition. This paper describes the pricing mechanism developed by Romania in order to respond to European Union requirements for ensuring a fair payment to pig producers. It raises the attention on the difficulties encountered by the producers in understanding the way the commercial value of a pig carcass is calculated in case the selling price is negotiated on a flat rate basis or on a lean content basis (per kg of carcass weight or per kg of live weight).

The experiment measured the effect of 2 hormonal growth promotion strategies on growth rate, carcass characteristics, and some objective measurements of meat quality of steers. Bos indicus × Bos taurus crossbred steers grazing improved tropical pastures were divided into 3 treatment groups: unimplanted controls, implantation once with a long-acting formulation containing 45 mg oestradiol-17β (Compudose 400, Elanco Animal Health, West Ryde, NSW), implantation every 105 days with a shorter acting formulation containing 20 mg oestradiol-17β (Compudose 100) (4 implantations). Over a 420-day experimental period, steers implanted several times with oestradiol gained significantly (P < 0.001) more weight (279 kg) than those implanted once (251 kg) and the controls (230 kg). Respective carcass weights were 270, 255, and 244 kg. At the same carcass weight, oestradiol treatment had no significant effect on beef yield or carcass fatness. Increased total beef yields from implanted steers were associated with increased carcass weight, rather than significant modification of carcass composition. Treatment had no significant effect on any of the objective measures of meat quality studied, including ultimate pH, peak force, compression, and adhesion.
