Effect Of Feeding

The research was conducted on the effect of bird broilers fed with different hybrid rye doses on the fatty acids profile in muscle. The first experiment was performed on 3 geese broilers groups fed with hybrid rye, oats or hybrid rye and oats mix in proportion 1:1. No effect of the hybrid rye feeding of geese on the SFA level in meat was observed, but the MUFA level was significantly higher and PUFA level and n-6/n-3 PUFA ratio were significantly lower than in geese fed with oats. The second experiment was performed on 3 chicken broiler groups fed with mix of corn, wheat, soybean meal and rapeseed oil (control group), and fed with an addition of 10% or 20% hybrid rye in diet (experimental groups). No effect of hybrid rye feeding of chicken broilers on the meat quality and SFA level was observed. However, the MUFA level was higher and the PUFA level and n-6/n-3 PUFA ratio were lower in meat of chicken broilers fed with hybrid rye. In conclusion hybrid rye is a healthy ingredient in the diet of studied birds and may be used up to 20% in chicken broilers and 50% in the diets of geese. A 100% hybrid rye in geese diet caused lower final body weight.

Abstract Background: With increasing of duck meat among consumers, the demand for growth performance and the meat quality health of ducks in increasing. Dietary curcumin altered the growth performance and meat quality. However, study on the effect of dietary curcumin on the growth performance, serum antioxidation and meat quality of ducks. This study invested effects of dietary curcumin given to ducks on the growth performance, antioxidation capacity in plasma, meat quality, lipid oxidation and the concentration of volatile compounds in duck breast muscle. A total of 600 healthy ducks with similar body weight were randomly allotted into 4 groups with 10 replicates per group and 15 ducks per replicate. Ducks were fed experimental diets which the curcumin supplemental levels were 0, 300, 400 and 500 mg curcumin/kg basic fed, respectively. The experiment lasted for 10 weeks. Results: Results showed that dietary supplementation of curcumin at levels 300, 400 and 500 mg/kg dietary (P < 0.05) improved the average final body weight. The ducks fed the basal diet without curcumin supplementation had the lowest FI (P > 0.05) and highest FCR (P > 0.05) among all ducks. Feeding ducks on diets supplemented with curcumin at each level significantly increased (P < 0.05) plasma activity of T-SOD and GSH-Px, and significantly reduced plasma MDA concentration compared to the control group. The dietary curcumin significantly increased the growth performance and the antioxidation capacity in plasma of ducks. Dietary curcumin improved the meat quality of ducks by significantly increasing pH45, pH24 (P < 0.05) and color of duck meat (P < 0.05), and significantly decreasing cooking loss (P < 0.05), shear force (P < 0.05), and the lipid oxidation of duck meat. 56 volatile compounds were identified and quantified. Interestingly, cantharidin among volatile compounds was firstly found in duck muscle, and only existed in the group of 500 mg curcumin/kg diet. Conclusions: In conclusion, the supplementation of duck diets with curcumin at 300, 400, and 500 mg/kg diet improved growth performance, antioxidant status and meat quality of ducks. The cantharidin was firstly found in duck breast muscle when the dietary curcumin inclusion of 500 mg/kg.

Fatty Acids Profile

Background: Organic acid as a green feed additive is increasingly favoured by enterprises and scholars, but little emphasis has been placed on the effect of organic acids on broiler meat quality. Methods: A total of 192 male chicks (one-day-old, weighted 48.40 ± 0.64 g) were selected to investigate the effect of mixed organic acids (MOA) on growth performance, meat quality as well as fatty acids profile. Chicks were randomly allocated to three treatments with eight replicates and eight chicks per replicate, including a corn–soybean basal diet with 0 (CON), 3000 mg/kg (low MOA; LMOA), and 6000 mg/kg (high MOA; HMOA) MOA. The experiment was divided into starter (d 1–d 21) and grower (d 22–d 42) phases. Results: Broilers supplemented with LMOA and HMOA enhanced (p < 0.05) the final body weight and average daily gain in the grower and overall phases. An improved (p < 0.05) feed conversion ratio in the grower and overall phases was observed in broilers supplemented with LMOA. The breast and thigh muscles pH24h were higher (p < 0.05) in broilers fed with HMOA and the redness in thigh meat was also improved (p < 0.05). Additionally, supplementing LMOA increased (p < 0.05) the saturated fatty acids, unsaturated fatty acids and the ratio of polyunsaturated fatty acids to saturated fatty acids in breast meat. A positive effect occurred (p < 0.05) on jejunal villus height and ileal crypt depth in 21 d broilers supplemented with HMOA. Conclusion: Our findings indicated that dietary supplementation of MOA could improve the growth performance, meat quality, and fatty acids profile, as well as intestinal morphology. Furthermore, diets supplemented with mixed organic acids at 3000 mg/kg may be more desirable, considering the overall experimental results in broilers.

AbstractThe aim of this study was to determine the effect of feeding rabbits with diets containing dried silkworm pupae and mealworm larvae meals on their slaughter value and meat quality. A total of 60 New Zealand White rabbits at 35 days of age were divided into 3 equivalent groups. Control group (C) and two experimental diets included either 4% silkworm pupae meal (diet A) or 4% mealworm larvae meal (diet B). The experiment lasted for 55 days and growth performance as well chemical and amino acid meat composition and the profile of fatty acids were evaluated during the study. The results showed that dietary supplementation of insect meals caused increases in final body weight and carcass meat content in rabbits from the experimental groups. The experimental diets had no effect on the sum of essential amino acids in the studied muscles, but created differences in the level of some amino acids: phenylalanine, lysine, tryptophan, threonine, isoleucine and methionine. The concentration of saturated (SFA) and monounsaturated fatty acids (MUFA) in the muscles was comparable in all the groups. In the tissues of rabbits fed the silkworm meal diet, PUFA-3 concentration increased and cholesterol level decreased. It is concluded that dried silkworm pupae and mealworm larvae meals can be used as feed material in rabbit diets at 4% inclusion level without any adverse effect on growth performance, as well as quality and dietetic value of rabbit meat.

Effect Of Feeding

Background : Female menstrual changes in hormone concentration influence appetite and eating behavior. As well, eating pattern has some influences on menstrual hormonal status. Feeding date palm fruit has been found in our previous report to affect menstrual hormones and some menstrual parameters. Objective: The aim of this research is to study the effect of feeding dates on energy, macronutrient, and fiber intakes, body weight, and body fat%. Additionally, this study aims to find any correlation between menstrual hormone concentration and the above-mentioned parameters. Methods: A convenient sample (n=37) of not-sexually active females aged 20-30 were divided into two groups; one group (dates group) was fed 7 dates and the other served as a control group. The participants of the control group were exposed to the same experimental conditions except for eating dates. Throughout the feeding trial, the volunteers filled a 3-day food record; one menses day and two non-menses days. Results: There was a significant effect of the menstrual status-feeding duration interaction in terms of protein and fat intakes. Additionally, menstrual status, as well as feeding duration, affected energy and macronutrient intakes significantly. Furthermore, feeding duration affected fiber intake significantly. Despite the above-mentioned differences in energy and macronutrient intakes, these effects didn’t affect the body weight and body mass index of the study participants, neither their body fat%. Moreover, we have found significant correlations between nutrient intakes and menstrual hormone concentration. Conclusion : Feeding dates affected energy, macronutrient, and fiber intakes significantly. These effects were related to the changes in menstrual hormone concentration.

Abstract This study evaluated the effect of roughage:concentrate (R:C) ratio associated with a variable particle size of physically effective neutral detergent fibre (peNDF8) in the forage (Tifton-85 hay) on the performance, carcass traits and meat quality of lambs. Seventy-two 4-month-old, non-castrated Santa Ines male lambs (23.5 ± 2.32 kg BW) were distributed in a completely randomized design, in a 2 × 2 factorial arrangement [two peNDF8 hay particle sizes (13 and 6 mm) and two R:C ratios (700:300 and 500:500 g/kg DM total)]. DMI, DM, NFC and TDN digestibility's, N-intake and N-faecal excretion were affected by the R:C ratio (P < 0.05). However, the N-retained was not affected by the studied variables (P > 0.05). It was observed an interaction (P < 0.05) between the peNDF8 and R:C ratios for final BW, average daily gain (ADG), colour parameters and pH 24 h. The lower roughage ratio provided greater (P < 0.05) concentrations of C14:1, C16:1–cis9, C18:1–cis9, ΣMUFA, Σn–6:Σn–3 and hypocholesterolemic/hypercholesterolemic index, enzymatic activity Δ9desaturase-C16 and -C18. Lambs fed a lower roughage diet had improved performance and feed efficiency, however, presented reduced polyunsaturated fatty acids (PUFA) concentrations in the meat, especially Σn–3 family. Higher roughage diet and larger peNDF8 particle size improved the concentrations of PUFA while decreased Σn–6:Σn–3 ratio in meat. Larger peNDF8 particle size associated with higher roughage proportion, have reduced animal performance however, it increased protein concentration, a* and C* colour parameter without affecting fatty acids profile of Longissimus lumborum muscle.

Lamb Meat

In the present study, the evaluation of the carcasses and meat quality, in terms of chemical composition and fatty acid profile, of lambs from five autochthonous sheep breeds (Altamurana, Bagnolese, Gentile di Puglia, Laticauda, and Leccese) reared in continental Southern Italy, were studied. All the carcasses were evaluated according to the EU Mediterranean classification system for carcasses weighing less than 13 kg. Meat chemical composition and fatty acids profile were assessed on both loin and leg commercial cuts. Fatty acid composition of loin resulted in differences among breeds, displaying lower values of saturated fatty acid in Altamurana, Bagnolese, and Leccese breeds and the highest content of polyunsaturated fatty acid in the Altamurana breed. Principal component analysis grouped lamb according to fatty acid content and to conjugated linoleic acid (CLA), omega n-3 and n-6 fatty acids; thus, Altamurana, Bagnolese, and Leccese breeds are characterized by the highest values of CLA content. Our data demonstrated that lamb meat from autochthonous breed has good carcass quality and the content of CLA, n-3, and n-6 was valuable for human consumption; therefore, the valorisation of local meat quality can help to avoid the extinction of the autochthonous breed offering to the market and consumer’s high nutritive products.

The Impact

Background: The intensive rearing systems of goats needs dietary formulations that will meet animal requirements, mainly the protein and energy to allow optimum growth rate. Alternative systems to attain 15-20 kg body weight by three months of age with better meat quality is need of the hour. Broiler goat production system is most suitable system of rearing for meat goat production. The current study was conducted to examine the impact of broiler goat production system on the carcass traits and meat quality characteristics of Malabari male kids. Methods: Fourteen pre-weaned kids were randomly allotted to two treatments. Treatment-I (T1) kids were allowed to suckle thrice a day during four weeks and twice in a day during consequent weeks. Whereas in Treatment-II (T2), kids were reared intensively by providing finely ground concentrate feed mixed with equal quantity of rice gruel from a feeding bottle after 7 days of colostrum feeding from the mother. The animals were slaughtered at an age of three months and the final body weight, carcass traits like dressing percentage, weight of different body parts and meat quality parameters like pH, color, cooking loss and shear force were analysed. The proximate composition and sensory evaluation was performed. Result: Broiler goat production system could produce significantly (P less than 0.01) higher final average body weight compared to natural system. All the carcass traits were significantly (P less than 0.01) higher in T2. The broiler goat production system could double the net live weight during the same period compared to natural suckling system with higher dressing % and the chevon produced was tender with less cooking loss. Hence, this system can be recommended for chevon production in shorter period with higher dressing % and lesser cooking loss in Malabari male kids.

Advances in molecular genetics have allowed the identification of genes that can enhance livestock production. The aim of this study was to investigate possible relationships between the calpastatin (CAST) Hha1 gene polymorphisms and growth performance, carcass characteristics, and meat quality in Awassi sheep. A total of 87 blood samples were collected from two-week-old Awassi ram lambs. The amplification of the CAST Hha1 gene yielded a fragment of 622 bp. Three CAST genotypes were found in Awassi sheep: MM for two fragments (385 bp and 281 bp), MN for three fragments (622 bp, 385 bp, and 281 bp), and NN for only one fragment (622 bp). The M and N allele frequencies of the CAST Hha1 genotypes were 0.765 and 0.235, respectively, while the genotypic frequencies of MM, MN, and NN were 0.586, 0.356, and 0.057, respectively. Based on CAST Hha1 gene polymorphisms, three groups of lambs (MM: n = 8; MN: n = 6; and NN: n = 3 genotypes) were subjected to a fattening period of 70 days to investigate growth performance and meat characteristics. Only the final body weight and longissimus muscle width were significantly different between the three genotypes, while no significant differences were detected in any other carcass characteristics and meat quality parameters. In this study, new variants were observed in CAST using the Hha1 restriction site, potentially assisting in Awassi sheep breeding and selection programs to improve final body weight and longissimus muscle width.

The present study was conducted to evaluate the effect of different levels of methionine supplementation on feed intake, nutrient digestibility and growth performance of growing rabbit. Sixteen weaned crossbred New Zealand White (NZW) growing rabbits (30-35 d) were distributed into four treatment groups having four replications in each group using a Completely Randomized Design (CRD). Basal diet composed of green grass (dhal grass) and concentrate mixture which was offered ad libitum basis for 56 days period. Four levels of methionine such as 0.0% (control), 0.15%, 0.25%, and 0.35% were supplemented randomly to rabbits. Results showed that supplementation of methionine did not affect green grass intake. Cumulative as well as daily concentrate and DM intake were significantly (p<0.05) higher for all methionine groups than control group. Final body weight gain as well as daily, weekly and cumulative body weight gains were improved significantly with increasing level of methionine. It was found that methionine had significant (p<0.01) effect on digestibility of DM, CP, NFE and EE but CF digestibility did not differ significantly. Digestibility was improved with increasing the level of methionine. Feed conversion ratio also decreased significantly with methionine supplementation, and 0.25% methionine group showed the best performance among the four treatments.

The efficacy of tulsi (Ocimum sactum) and neem (Azadirachta indica) leaves extract as a growth promoter were studied in broiler. A total of 40 day-old broiler chicks were purchased from Kazi hatchery and after three days of acclimatization the chicks were randomly divided into four groups (n=10). No vaccination schedule was practiced and no antibiotic was added in ration of group A, B, C, and D respectively. Group A served control without any supplements while group B, C and D were supplemented with combination of tulsi and neem extract @ 1 ml, 2ml and 3 ml/liter of drinking water. Live body weight gain was recorded weekly up to 6th weeks and hematological studies were performed at 21st and 42nd day of experiments. At the end of 42nd day of experiment final body weight of group A, B, C and D were 1561± 12.10 g, 1698± 12.87 g, 1608± 12.04 g and 1763± 13.28 g, respectively. The birds of group D utilized their feed more efficiently among the treatment groups (p<0.05). The net body weight gain were, 1533± 11.98 g, 1443± 11.32 g and 1588± 12.10 g in treated groups compared to control group (1393± 11.07 g ) and total net profit per broiler was 19.08, 40.10, 20.68 and 45.07 Taka , respectively. Hematological parameterss (TEC, PCV, Hb and ESR) were not significantly changed among the treated and control group suggesting no side effects of herbal extracts in broiler. It can be concluded that tulsi and neem extract is economic and safe in broiler production.DOI: http://dx.doi.org/10.3329/bjvm.v11i1.17728 Bangl. J. Vet. Med. (2013). 11 (1): 1- 5
