The study investigated the effects of lamb genotype produced from hill flocks on feed efficiency, carcass characteristics and meat quality in animals finished on either a high forage:concentrate ratio diet (HFC) or a low forage:concentrate ratio diet (LFC). Purebred Scottish Blackface (BXB) lambs were compared with Blue-Faced Leicester×Scottish Blackface (BLXB) and Texel×Scottish Blackface (TXB) lambs. Purebred Cheviot (CXC), Suffolk×Cheviot (SXC) and Texel×Cheviot (TXC) lambs were also investigated. Lambs on the LFC diet were offered grass silage and concentrates mixed in the proportion of 0·80 silage and 0·20 concentrates on a dry matter basis. The LFC diet consisted of 0·20 grass silage and 0·80 concentrates on a dry matter basis. Representative lambs were slaughtered at the start of the experiment and on reaching 38 and 46 kg live weight. Averaged over the two slaughter weights, within the Blackface cross lambs, BXB had a lower liveweight gain (P < 0·01) than either BLXB or TXB (138, 207 and 203 (S.E. 11·1) g/day, respectively). Within the Cheviot cross lambs, CXC had a lower liveweight gain (P < 0·05) than SXC (188 v. 220 (S.E. 11·1) g/day), while SXC and TXC (204 g/day) had similar liveweight gains. Lambs on the LFC diet had a higher dressing proportion (P < 0·001) compared with lambs finished on the HFC diet (0·466 v. 0·434 (S.E. 0·0018) kg carcass per kg live weight). Averaged over the two slaughter weights BXB lambs had a lower (P < 0·05) dressing proportion than the other genotypes. Carcass conformation classification (assessed on a five-point scale) was higher (P < 0·001) in lambs finished on the LFC diet (3·0 v. 2·4 (S.E. 0·04)). Conformation classification was higher in lambs produced from Cheviot compared with Blackface ewes (P < 0·05). Within the Blackface cross lambs, BXB and BLXB lambs had a lower conformation classification (P < 0·001) than TXB lambs (2·4, 2·4 and 2·9 (S.E. 0·08) respectively). Within the Cheviot ewes, TXC lambs had a higher (P < 0·001) classification than either CXC or SXC (3·1, 2·7 and 2·7 (S.E. 0·08) respectively). Lambs finished on the LFC diet had a higher fat classification score compared with lambs on the HFC diet (P < 0·001) (3·4 v. 2·8 (S.E. 0·04)). Fat classification was similar across all genotypes. Lambs finished on the LFC diet had a lower ash content in the carcass than lambs finished on a HFC diet (P < 0·01) (44 v. 47 (S.E. 0·8) g/kg). Lamb genotype and dietary forage:concentrate ratio had no significant effect on cooking loss, sarcomere length, Warner–Bratzler shear force and L* values. Ultimate pH (pHU) was not influenced by dietary forage:concentrate ratio, but was significantly (P < 0·01) higher in BXB lambs compared with BLXB, TXB, CXC and TXC lambs. Lambs offered the LFC diet during the finishing period had significantly higher values for a* (P < 0·05), b* (P < 0·001), C* (P < 0·001) and H0 (P < 0·05) than lambs offered a HFC diet. Of these parameters only b* was significantly affected by lamb genotype, with BXB lambs having a lower value (P < 0·05) than the other genotypes.

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.

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 has been carried out on a crossbred stock of young pigs in the period 2015–2017 under the conditions of JSC CHC “Krasnodonskoe” in the Ilovlinsky district in the Volgograd region. The purpose of the research was to study the effectiveness of the effect of the anti-stress drug Feed-Food Magic Antistress Mix in intensive pig rearing on the productive traits and quality of the products obtained, as well as the estimated economic indicators. In order to conduct a scientific and economic experiment at the age of 60 days young pigs were divided into 2 experimental groups (control and experimental) according to the principle of pair analogs. Each group contained 25 heads. The difference between the control and experimental groups was that the animals in the control group have received the main diet, and the experimental group has received the anti-stress drug Feed-Food Magic Antistress Mix in addition to the main diet. In the experimental group of pigs when this drug was administered in the age 180 days the live weight parameter was higher than in the control group by 1,55 kg. Clinical indicators of young pigs were within the physiological norm. The pre-slaughter weight in the experimental group has increased by 4,86 % compared to the control group. Due to the use of an anti-stress drug the slaughter weight of animals in the experimental group has increased by 6,69 %. In comparison with the control group the slaughter yield in the experimental group has increased by 1,18 %, in which this indicator was at the level of 67,62 %. The morphological composition of carcasses in animals of the experimental group was also improved. Meat yield has increased by 0,95 %. The yield of fat and bones has decreased by 0,59 and 0,36 %. The weight of internal organs was also superior in the experimental group of pigs. Due to the use of the anti-stress drug the level of profitability in the experimental group of animals has increased by 11,69 %.

Under the predicted conditions of climate change, the productivity of temperate grasslands may be affected by drought stress, especially in spring and summer. In this scenario, water-deficit-tolerant species such as plantain and chicory are interesting alternatives for use in sheep production systems. In this study, we compared a mixture of plantain and chicory herbage (PCH) with a grass-based permanent sward (GBS) on the weight gain and meat quality of lambs finished on these grasslands. Fifteen weaned lambs (31.3 kg and 4 months of age) were assigned to each treatment for seven weeks in late spring and live weight gain (LWG), carcass and meat quality were evaluated. There was a tendency (p = 0.09) in final weight (40.3 ± 0.8 kg) and live weight gain (173 ± 10 g/d) to be higher in PCH compared to GBS. Carcass weight, dressing percentage and meat quality in terms of pH, color and tenderness did not differ (p > 0.05) and were considered to be of good quality. We concluded that both swards result in comparable lamb performance and good meat quality.

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 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

SUMMARYThe objective of the present study was to determine the pasture intake of European wild boar and domestic pigs throughout their growth period (from 60 to 207 days of age). The proportion of time that each animal type spent grazing was also determined. Twelve 60-day-old pure-bred European wild boar (six castrated males and six females, average live-weight (±s.e.m.) 6·8 ± 0·37 kg) and 12 70-day-old domestic pigs (Large White × Landrace, six castrated males and six females, average live-weight [ ±s.e.m.] 24·1 ± 0·66 kg) were used in the study. Each day during the study, the animals grazed from 08·00 until 16·00 h, after which they hadad-libitumaccess to a supplemental diet for 1 h. Every 14 days throughout the study (a total of ten determinations), the pasture consumption was determined as the difference between the pasture dry matter (DM) availability pre- and post-grazing. The supplemental diet consumption was also determined. Three times during the study (age of animals 85, 140 and 198 days), the behaviour of each animal was observed over four consecutive days while grazing. When considered on a metabolic bodyweight basis, the pasture consumption of the European wild boar was greater than that in the domestic pigs. Approximately 0·20 of the total DM intake by the wild boar was pasture, whereas only 0·10 of the total DM intake by the domestic pigs was pasture. However, domestic pigs consumed a greater quantity of supplemental diet than the wild boar. The wild boar obtained 0·20 of their total daily dietary apparent energy intake from pasture, compared with 0·07 in the domestic pigs. Wild boar were more active during 8-h grazing periods spending 0·54 of their time grazing or moving around, compared with 0·32 of the time in domestic pigs.
