Effect of dietary supplementation of Ashwagandha (Withania somnifera) and Selenium on growth performance and carcass quality of broilers

In this trial we aimed to assess the effects of dietary supplementation of 4-O-methyl-glucuronoarabinoxylan (4OMG) on growth performance, thigh meat quality and small intestine development of female Partridge-Shank broilers. A total of 240 1-day-old female Partridge-Shank broilers were randomly distributed to four groups with three replicates of 20 within each group. Groups received either 0, 15, 20 or 25 g 4OMG/kg DM of diet. During the whole experiment of 60 days, broilers had ad libitum access to water and feed. At pen level, feed intake was recorded daily and broilers were weighed at the start and end of the experiment. For each group, three pens with a total of 20 broilers were randomly selected to determine the thigh meat quality and the small intestine development of broilers. Broilers fed diets with higher 4OMG had greater final liveweight (P = 0.004), daily bodyweight gain (P = 0.004) and gain-to-feed ratio (P < 0.001), muscle pH values (P = 0.031) and redness (P = 0.001), duodenal weight index (P = 0.042), jejunal (P = 0.043) and ileal length (P = 0.049), duodenal (P < 0.001) and ileal villus height (P = 0.008), but lower percentage of dead birds (P < 0.001), drip loss (P = 0.042) and shear force value (P = 0.043) of the thigh muscles. These results indicate that increasing dietary supplementation of 4OMG may improve growth performance and meat quality of female Partridge-Shank broilers through better development of small intestine.

Study Performance

Fattening of farm animals is a way of increasing the rate of meat deposit after maturity. Its effectiveness depends on genetic status of the animal and the diet fed to the animal. In this study, performance and carcass evaluation of balami rams finished on diets with varying energy levels were carried. Forty-eight rams of Balami breed, weighing 20.75±1.50- 22.50±1.91kg were randomly alloted to four dietary energy levels (EL): 2.20Mcal/kg (EL ), I 2.40 Mcal/kg ((EL ), 2.60 Mcal/kg ((EL ) and 2.80 Mcal/kg ((EL ) for 90 days. The feed II III IV intake and daily weight gain of the animals in each treatment were determined and the average recorded. Three Balami rams were randomly selected from each treatment and sacrificed to determine the dressing percentage (DP), carcass weight (CW), fat deposit (FD) and meat yield (MY). Data were analysed using descriptive statistics and ANOVA at á . The 0.05 FBW (kg) of Balami rams in group EL , EL , EL and EL were 41.88.6±1.97, 42.12±1.84, I II III IV 46.13±1.65 and 52.24±2.50 while the FCR of animals on treatments EL (5.3±0.28) and EL I II (5.2±0.26) were higher than EL (4.7±0.82) and EL (4.0±0.65). The DP (%) were 54.9, III IV 54.9, 55.8 and 56.1, the FD (%) were 9.00,9.59,8.92 and 11.46 and the MY (%) were 75.2, 74.7, 75.5 and 72.0 for rams on EL , EL , EL and EL The results indicate that, increasing I II III IV. levels of energy improved growth performance and carcass quality of Balami rams. Therefore, higher level of dietary energy (2.80 Mcal/kgDM and 14% CP) could be suggested for optimizing growth performance and meat quality of Balami ram under fattening condition.

Consumer acceptability of lamb is ultimately determined by the eating quality of the meat. This paper reports on the eating quality evaluation of lean samples obtained from carcasses of crossbred lambs sired by Suffolk, Texel and Charollais rams.The lambs used in this study were part of a larger experiment to compare the growth performance and carcass quality of lambs sired by rams of the Suffolk, Texel and Charollais breeds (Merrell, Webster and Ellis, 1990: BSAP Occasional Publication No. 14, pp. 169-172).An upland flock of approximately 350 Mule (Bluefaced Leicester ♂ x Scottish Blackface ♀) was used to produce the lambs. Eight unrelated rams of each of the three sire breeds were mated to the ewes over two years (4 rams per breed per year). Their crossbred progeny were selected for slaughter when it was estimated that they would produce carcasses of Meat and Livestock Commission fat class 2 to 3L. All lambs had been multiple-born and reared as twins.

Significant Difference

SUMMARYGrowth performance and carcass quality (linear measurements) were studied in pigs grown from 25 to 90 kg on barley stored and prepared in different ways. Half the barley was dried to about 14% moisture content for storage and half was not dried but treated with 0·8% propionic acid. Each was given after hammer-milling (3·2 mm screen) or rolling. A total of 144 pigs was used at four centres.The performance and carcass quality of pigs given acid-treated barley were as good as those given dried barley. While feed utilization, expressed on the basis of air-dry feed, was poorer for pigs fed on acid-treated barley this difference disappeared when account was taken of the different moisture contents of the barley samples. Pigs fed on diets based on milled barley grew more quickly, had better feed utilization but greater fat measurements than pigs fed on rolled barley. There was a significant interaction between storage method and feed preparation (milling or rolling). Pigs given the acid-treated barley grew more quickly when it was in the milled form than when it was rolled, whereas for the dried barley there was a small, non-significant difference in favour of the rolled form.
