Gracilaria sp is as eaweed with carbohydrate-rich wastes. Its symbiont, Brotia sp,is rich in calcium and protein. The effects of Gracilaria’s wastes (GW) as formulated feed supplement on carcass characteristics and production efficiency of local Indonesian ducks. Data were collected from 120 ducks fed either a basal dietor a fermented Gracilaria’s wastes supplemented diet (FGW). Treatment levels of FGW were 10%, 12.5%, and 15%. The highest level of meat antioxidant status was reached at 15% FGW, while the optimum level of FGW for decreasing the fat content was 12.5%. The best reduction in meat fat mass was at 15% FGW. Further more, duck feed with FGW resulted in lower average and normalized costs and increased income than observed with the basal diet. Thus, GW as a feed supplement effectively ameliorated the productivity and carcass quality of indigenous Indonesian ducks.

Effect On Growth

The effects of sex and age of castration of males on growth rate, feed efficiency and carcass characteristics in bacon type swine were measured using 16 pigs each as gilts, entire boars, and boars castrated at birth, 6, 12, 16, and 20 weeks of age. Castration at 20 weeks was too late since some pigs reached 200 pounds live weight before that age. Boars consumed less feed daily than barrows and gilts, were thinner in loin fat, and yielded a higher percentage of shoulder than gilts. The carcasses of boars and gilts were longer, had less fat covering over the shoulder and back, a larger area of loin, and a higher iodine number than those castrated late. Acceptability tests showed that sex or age of castration did not affect the flavour, odour, or tenderness of the meat.Purebred breeders can delay castration for better selection of boars without any serious effect on growth, physical carcass characteristics, and feed requirements. Although the market discriminates against boars, it appears questionable whether castration is necessary when boars are slaughtered at 200 pounds before they reach the age of 150 days.

Recently ,there is an incrase interest in fattening camals in Iran .This trial aimed to define the influence of dietary energy and protein levels on performance and carcass quality of camels in khorasan province.For 80 days, nine diets with three metaboliseble energy 10.9, 8.8 or 7.6 MJ /kg DM and three crude protein levels 140, 120, or 100 g/kg DM were offerd ad lib to thirty six camels (mean initial weight 183 kg ± 7.7) , where each treatment were randomly allocated to four animals, that were housed individually. Food intakes were recorded daily. Throughout the trial , all animals were weighed at fortnightly intervals. At the end of the project ,two animals from each treatment were slaughtered and carcass quality were determined. Data were analysed as a 3x3 factorial Anova, with energy and protein were the main effects.

ABSTRACTCarcass characteristics of 246 bulls and steers by Dairy Shorthorn (DS), Red Friesian (RF), Red Holstein (RH), Danish Red (DR), Meuse-Rhine-Yssel (MR), Simmental (SM) and North Devon (BB) bulls were recorded as part of a breed improvement programme. Carcasses of animals on grass-feeding systems were older, had lower fat and conformation scores and higher estimated lean yield than on intensive cereal systems, BB were fatter, and MR and SM leaner, than the remaining breed groups which were similar to DS and SM progeny had high conformation scores. Estimated lean in the live weight (g/kg) relative to DS was RF +5, RH −3, DR +5, MR +16, SM +16 and BB +6 with an average standard error of 3.

SUMMARYTwo experiments were carried out to compare the performance and carcass quality of pigs given diets based on barley, wheat or maize meal, and another two experiments comparing these cereals, flaked maize and sorghum. In general, differences in the utilization of feed for live-weight gain could be related to differences in the digestible energy content of the cereals used in the diet, although in some experiments pigs behaved atypically on individual diets. Flaked maize was consistently inferior to the other cereals in the efficiency of conversion of its digestible energy, possibly because of its poorer amino acid balance and its low levels of lysine and tryptophan in relation to energy. Differences between experiments in the performance of pigs fed on the various diets are also discussed. Differences between treatments in killing-out percentage and predicted lean percentage were small, and carcasses of pigs from all treatments were acceptable for bacon curing.

Ninety-six Yorkshire pigs, reared during the growing period on high energy–high protein rations, were used in a 2 × 2 factorial feeding experiment to compare two levels of protein at two levels of energy in self-fed finishing rations. Pigs fed a high energy ration gained 0.34 lb more per day, consumed less feed, had more loin and back fat, lower Record of Performance (R.O.P.) scores, and received lower commercial grades than those fed the lower energy ration. The level of protein fed did not affect significantly, rate of gain, feed utilization, or carcass quality. An interaction existed between protein and energy whereby the adverse effects on carcass quality of the high level of energy were modified by the high level of protein with the result that average loin area was increased and a higher R.O.P. score and a higher percentage of grade A carcasses was obtained.

Abstract High production efficiency is crucial for the competitiveness and sustainability of the dairy industry. To maintain high production, maximize profitability, and allow an accelerated genetic improvement, it is recommended that between 25–30% of dairy herds be renewed each year. Cull dairy cows contribute for approximately 10% of the total beef produced in the United States, being significantly important as a beef source for the meat industry. Furthermore, cull cows provide an important additional income to dairy farmers. However, culling decisions should be carefully made, taking into consideration herd replacement rate, cow performance, milk and beef prices, and the potential price that each cow might be paid for. The objective of this study was to investigate the relationships between life history factors, live animal auction price, and carcass quality of cull dairy cows. Data from three Wisconsin herds were collected using DairyComp software, from January 2018 to January 2019. Hundredweight (cwt) prices paid for each cow (n = 84) were obtained from a marketing auction, and their carcass traits were provided by a commercial meat packing plant. Correlation and multiple linear regression analyses were used to investigate the dependencies between variables. Results indicate that lactation number and days in milk significantly affect cow live weight and that these three variables together with season of the year and farm provide a good predictor of cwt price (adj R2 = 71.7%). Moreover, there were also significant and moderately strong correlations between cwt price and some carcass quality indicators such as dressing (r = 0.57, P < 0.001), trimming losses (r = -0.25, P < 0.05), and grade (r = -0.58, P < 0.001). In conclusion, cull cow cwt price and carcass quality can be improved by taking into account cows life history factors when making culling decisions.

The Impact

A total of 150 broiler chicks were used to determine the impact of dietary cinnamon bark powder (CBP; Cinnamomum verum) on breast meat quality, growth performance, and carcass characteristics of birds under coccidiosis, as one of the protozoan parasitic diseases. A total of 5 replicates of birds received 1 of the following 6 groups for 34 days: control groups (1 and 2) received a basal diet without the addition of CBP or salinomycin; group 3 received a basal diet with 0.066 g salinomycin; groups 4–6 were given a basal diet supplemented with 2, 4, and 6 g CBP/kg feed, respectively. On day 21, 4 × 104/100 µL of Eimeria tenella oocysts/bird were challenged, except for the negative control (NC). At the end of the experimental trial, five birds/group were sampled for carcass characteristics and breast attributes. Overall, emeriosis negatively affects slaughter body mass, carcass yield, and the majority of carcass characteristics in birds, and cinnamon can mitigate these effects. Cinnamon groups, particularly at the 2 g level, alleviated the negative effect on performance caused by coccidia infestation to the same or greater extent as the negative control and salinomycin treatment groups. Furthermore, when compared with the other experimental groups, the addition of cinnamon improved some physicochemical properties with some affecting meat quality, such as decreasing MFI and increasing toughness in cinnamon-treated groups. In summary, it can be concluded that CBP can enhance the shelf life, carcass, and quality of birds’ meat by maximizing the productive performance efficiency and breast meat productivity of birds under coccidiosis infestation. Further research is required to investigate the use of cinnamon to optimize the quality of meat and the productivity of both healthy and diseased broilers.

Abstract. Title of the paper: Application of Echinacea-extract in pregnant and suckled sows In an experiment with thirteen sows (echinacea: n = 6; control: n = 7), the influence of Echinacea purpurea treatment of pregnant and suckled sows on immune system, health status, growth performance, and carcass quality of the offspring (echinacea: n = 69; control: n = 79) was investigated. Echinacea was given as liquid feed supplement during the whole pregnant and suckling period of sows in six intervalls (5 days of treatment, followed by 2 weeks of break, respectively). During the treatment time the daily dosage per sow in echinacea-group was 0.125 ml preparation of echinacea extract (incl. solution)/kg body weight. To measure the concentrations of immunoglobulin G (IgG), immunoglobulin A (IgA) and C-reactive protein (CRP) in serum, blood samples were taken by punction of V. cava cranialis (sows and piglets) at different times. The treatment of sows resulted in immunostimulatory effects both in sows and piglets with highest changes in peripartal period. In one day old piglets, the concentrations of IgG, IgA and CRP were significantly increased in echinacea-group (P = 0.0004, P < 0.0001, P = 0.05, respectively). Up to day 70 of age, the rate of therapeutical treatments of piglets from echinacea-treated sows was decreased in tendency (P = 0.08). The growth performance and carcass quality of offspring was not influenced by echinacea treatment of sows.

SUMMARYThree trials, each involving 24 pigs, were conducted to assess the value of Hormonexa as a feed supplement for pigs slaughtered at 90 kg live weight. Rations were compounded from a variety of feeding stuffs to different protein levels and the pigs were fed on various nutritional planes. Hormonexa was added to these rations at the rate of 1·32 kg per 1000 kg meal.In all three trials growth rate and food conversion efficiency were not affected significantly by the addition of the supplement. There was a tendency for the pigs receiving the supplement to be slightly leaner but in only 1 out of 39 measurements of fat thickness was the difference between control and supplemented pigs statistically significant (P< 0·05).No benefit from this feed supplement has been demonstrated in terms of animal performance or carcass quality under a range of feeding systems.

Selection For

There have been a number of reports that voluntary feed intake (VFI) of modern pig genotypes may be the limitation to their growth performance. It has been suggested that selection for leanness (Fowler et al. 1976) and breeding for faster growth may have reduced appetite.In addition there is only limited information about the effect on VFI, performance and carcass characteristics of pigs fed ad libitum to liveweights greater than 100kg. A study was therefore undertaken to compare VFI and energy intake of improved genotypes with predicted intakes based on earlier genotypes (ARC, 1981). The associated effects on performance and carcass characteristics at heavier slaughter weights were also studied.
