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.

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.

Twenty-one Friesian steers were grown to a final fasted liveweight of 469 kg. Seven of the steers grazed irrigated ryegrass-white clover pastures, seven steers were fed on a high energy ration ad libitum, and seven were given a ration of the same composition as the second group but at a restricted amount such that the growth rate was similar to that of the grazing steers. There were no significant differences in carcass weight between the three groups. The dressing percentage of the grain ad libitum group was 58%, the restricted grain group 57% and the pasture group 55%. The dressing percentage was significantly lower (P < 0.05) in the pasture group. The grain ad libitum group had 51.5% more (P < 0.05) oaental fat than the pasture group, and the restricted group 28.9% more (P < 0.05) than the pasture group. In dissections of the 9th, 10th and 11th ribs the grain ad lib. group had 35.4% fat, the restricted grain group 32.8% and the pasture group 26.5%, the proportion of fat being significantly (P < 0.05) lower in the pasture group than in the grain ad lib. group. No significant differences were found in either tenderness, juiciness or flavour between the three groups.

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.

Dietary Treatments

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.

The aim of the present study was to investigate the effects of induction hypothyroidism by propylthiouracil (PTU) on the growth performance and meat quality of fat-tailed Lori-Bakhtiari lambs. Eighteen Lori-Bakhtiari male lambs were randomly assigned to one of three groups (n = 6) and received daily treatments (gavage) consisting of 0 (Control: C), 10 (Low: L) or 20 (High: H) mg PTU/kg bodyweight/day for 60 days. PTU decreased plasma triiodothyronine and thyroxine concentration in both L and H (P < 0.0001). Lambs treated with PTU (L and H) had lower feed intake (P < 0.004), feed conversion efficiency (P < 0.003), and greater intramuscular fat than C lambs (P < 0.035). Meat from the L and H lambs had lower cooking loss and shear force, and also higher L* (lightness) than C lambs (P < 0.004, P < 0.015 and P < 0.025, respectively). The meat of H and L lambs was more tender than C lambs (P < 0.032). However, the meat of H lambs required fewer chews before swallowing than C lambs (P < 0.041). Generally, induction of mild hypothyroidism appeared to improve feed conversion efficiency and meat quality of lambs.
