Maternal Administration

The effects of salbutamol administration to pregnant sows on post-natal growth and carcass characteristics of the progeny were investigated. Salbutamol (4 mg/kg diet) was fed to sows during the first (0 to 38 days, TI), second (39 to 78 days, T2) or third (79 days to term, T3) trimester of pregnancy. At birth, maternal administration of salbutamol had no effect on body weight, dressing percentage or weights of liver, heart, semimembranosus and semitendinosus muscle in proportion to body weight in the progeny. No significant effects of maternal treatment with salbutamol on body weight, dressing percentage, semitendinosus muscle weight in proportion to body weight and loin eye area were observed in the progeny at 21 days. P2 fat depth at 21 days was greater (P < 0-05) in TI than in controls. The percentage of type I fibres in the deep portion of semitendinosus muscle was higher (P < 0.05) in treatment groups as compared with controls: 27.4, 42.8, 36.9 and 36.0% in control, TI, T2 and T3 respectively. At slaughter (90 kg), carcass and meat parameters including length, P2 fat depth, meat colour and drip loss were not affected by maternal administration of salbutamol. However, loin eye areas were larger in T1 than in controls. Larger loin eye areas, coupled with numerically (but not statistically) significant heavier carcasses and lower backfats, resulted in greater estimates of carcass protein mass in TI pigs as compared with controls (P = 0.06).

ObjectivesThe objective was to evaluate the effect of supplementing α- and γ-tocopherol vitamin E isoforms with corn oil and tallow on carcass characteristics and meat quality of pigs grown to heavier weights (>150 kg).Materials and MethodsIndividually fed pigs (n = 72; 36 barrows, 36 gilts; 28.55 ± 1.16 kg) were randomly assigned to 12 dietary treatments in a 2 × 6 factorial arrangement. Fat treatments were tallow and corn oil (5?). The vitamin E treatments included four levels of α-tocopheryl-acetate (ATA; 11, 40, 100, and 200 ppm) and two levels of mixed tocopherols (primarily γ-tocopherol; 40 and 100 ppm). Pigs were humanely slaughtered at approximately 150 kg. 45 min pH was taken at the 10th rib. After 24 h chill (4°C), carcass measurements were taken (carcass length, backfat depth at first rib, last rib, 10th rib and last lumbar, loin muscle area, and 24 h pH at the 10th rib). In addition, wholesale weights from the Boston butt (IMPS #406), shoulder picnic (IMPS #405), loin (IMPS #412), and belly (IMPS #408) and spareribs were recorded. Furthermore, bellies were divided into eight sections and the average depth was taken at each section and the vertical and lateral belly flex was measured. Drip loss was determined by suspending a 1.3cm chop at 4°C for 48 h and purge loss was determined from approximately 2kg vacuum packaged loin muscle sections at 0, 7, 14, and 30d. Objective (Hunter Lab Colorimeter XE Plus) and subjective (NPPC color, marbling and firmness scores) measurements were taken at the 10th rib. Data analysis were performed in SAS by least squares analysis of variance using the generalized linear model as a randomized complete block design. The individual pig served as the experimental unit and results were reported as least square means.ResultsThere were no differences in dressing percentage, 24 h pH, backfat depth, loin muscle area, primal cuts, purge loss, and drip loss between the two vitamin E isoforms. Fat treatments did not affect dressing percentage, 45 min and 24 h pH, backfat depth, loin muscle area, primal cuts, purge loss, drip loss as well as objective and subjective color. Although not significant (P = 0.07), pork from the γ-tocopherol pigs had a lower pH than the ATA treatment. The γ-tocopherol supplementation tended to have a lighter subjective color (P = 0.06) as well as increased L*, decreased a*, and increased the hue angle calculations at 7d shelf-life. The belly depth was greater (P = 0.01) along with higher lateral (P < 0.01) and a lower vertical (P < 0.01) flex for pigs fed tallow.ConclusionIn conclusion, feeding tallow to heavy weight pigs (150 kg) could improve belly firmness. Also, α-tocopherol did not improve shelf-life stability and γ-tocopherol could negatively affect subject and objective pork loin color.

The experiment was conducted to evaluate the effect of dried bloodrumen content mixture (DBRCM) on carcass characteristics of broiler chicks to replace soybean meal (SBM). A total of 225 unsexed day old broiler chicks (SASSO C44) were randomly distributed to five dietary treatment groups in a completely randomized design. Each treatment was replicated thrice with 15 birds per replicate. The experimental diets were formulated to contain 100%SBM+0%DBRCM (T1), 80%SBM+20% DBRCM (T2),60%SBM+ 40% DBRCM (T3), 40%SBM+60% DBRCM(T4) and 20%SBM+80% DBRCM (T5) in 56 days of age. At the end of the experiment, two male and two female birds per replicate were used to determine carcass characteristics. The result revealed that the edible carcass yield ranged from 977.9-1159.3g. The dressing percentage based on the edible carcass weight was 63.9 % (T1), 66.6 % (T2), 65.4 (T3), 64.2% (T4) and 63.1% (T5). There was no a significant difference (P>0.05) in both edible carcass yield and its dressing percentage. The commercial carcass weight was 937.4g (T1), 984.7g (T2), 962.0g (T3), 925.0g (T4) and 833.1g (T5) and the dressing percentage was 54.9%, 56.6%, 55.3%, 53.7% and 53.7% for T1, T2, T3, T4 and T5, respectively. Significant difference (P>0.05) was not observed in commercial carcass yield and its dressing percentage among the treatment groups. There was no a statistical marked difference (P>0.05) in total nonedible offal and edible offal. Females had more (P<0.05) breast meat than that of males. The abdominal fat and abdominal fat percentage were not significantly influenced (P>0.05) by a diet containing DBRCM. However, abdominal fat and its fat percentage were higher (P<0.05) in females than males. Based on this result, it could be concluded that DBRCM can replace soybean meal up to 80% substitution level without any adverse effect on carcass characteristics.

Records kept by the Bauchi Meat Company, on 2,264 cattle slaughtered for meat, form 1982, were analysed to study the influence of season and year on the weight of the body, carcass, bone, wholesale and retail cuts, and dressing percentage. Bothe season and year showed significant (P < 0.01) influence on triats measured. Body weight was lowest during the rains (345.39 ± 3.00kg) increasing steadily thereafter to attain its highest peak (397.87 ± 3.30kg) in the hot-dry season. Body weight were similar in 1982 (370.63 ± 3.91kg) and 1984 (365.24 ± 2.39kg) but superior (P < 0.01) to that of 1983 (357.63 ± 2.61kg) Warm carcass weight was highest in the hot-dry season (217.11 ± 2.05kg) and lowest in the cod-dry season (181.64 ± 1.96kg). The annual values were similar for 1982 and 1984 but superior (P < 0.01) to that of 1983 (183.80 ± 1.43kg). The wholesale and retail cuts were heaviest in the hot-dry season. The dressing percentage was highest in the rainy season (56.13 ± 0.12%) and lowest (49.81 ± 0.21%) in the cold-dry season (P < 0.01). On annual basis carcasses dressed best in 1984. (55.26 ± 0.07%) and least (53.17 ± 0.12) in 1982. Studies such as this conducted through many season, years and even decades are valuable in functional planning.

The purpose of this study was to examine the effect of short-term (7 days) undernutrition on Type I (soleus) and Type II (plantaris, gastrocnemius) muscles in rats. Male Sprague-Dawley rats ( N = 20) were randomly assigned to one of two groups: a control group ( n = 10) in which animals were allowed to have water and pellets ad libitum and an undernourished group ( n = 10) in which animals were allowed to have 37% of the total food intake of the control group and water ad libitum. Body weight and food intake were measured daily. After 7 days, rats were anesthetized and the soleus, plantaris, and gastrocnemius muscles and liver were dissected. Body weight, liver weight, muscle weight, Types I and II fiber cross-sectional area, and myofibrillar protein content were determined. After 7 days of undernutrition, the undernourished group showed significant decreases ( p < .05) compared to the control group in body weight, liver weight, muscle weight of soleus, plantaris, and gastrocnemius muscles, and cross-sectional areas of Types I and II fiber of the plantaris and gastrocnemius muscles.

Two experiments were carried out with Hereford and Aberdeen Angus steer calves to study the influence of feeding concentrate and hay in the ratios of 1:2, 1:1, 2:1; of feeding the concentrate in the pelleted and the ground form; of pelleting the entire ration; and of feeding the ration ad libitum and according to the body weight of the animal. All comparisons were not made in each experiment. Each lot in each experiment was made up of four Aberdeen Angus and seven Hereford calves. All animals were fed individually. Only the data obtained between 500 and 900 lb. body weight were considered in this paper. The animals were slaughtered as they reached 900 lb. and certain carcass data obtained.The steers fed concentrate to hay in the ratio of 1:2 made smaller daily gains, required more feed (T.D.N.) per unit of gain, had lower dressing percentages, and had less fat in their 9-10-11 rib sections than those fed rations with ratios of concentrate to hay of 1:1 and 2:1. The steers fed the 1:1 ratio made significantly smaller daily gains and required more feed per unit of gain than those fed the 2:1 ratio of concentrate to hay, but were not different in dressing percentage or percentage fat in the 9-10-11 rib sections.There were no significant differences between those steers fed their concentrate in the pelleted or ground forms. In one experiment, pelleting the entire ration resulted in significantly lower daily gains than pelleting only the concentrate and feeding the hay chopped, but in the other experiment there were no differences. Pelleting the entire ration resulted in no significant differences in feed efficiency, dressing percentage, or carcass grade. Limiting the daily consumption of feed to predetermined amounts dependent upon body weight did not influence efficiency of feed utilization or carcass characteristics as compared to ad libitum feeding.The Hereford steers that were fed in these two experiments made greater body gains per unit of feed consumed but had less body fat and in one experiment had lower grading carcasses than the Aberdeen Angus steers.

Twelve individually housed West African Dwarf (WAD) Bucks averaging 7.3 ±0.91kg were used to study the effect of varying levels of Bambara nut seed meal on the performance and carcass characteristics of West African Dwarf (WAD) Bucks. Four experimental diets designated A, B, C and D were formulated to contain 0, 10, 20 and 3096 Bambara nut meal (BNM) respectively. The twelve WAD bucks were divided into four (4) groups of three animals each. Each group was assigned to one of the four experimental diets in a completely randomized experiment. Each animal in a group represented a replicate. The experiment lasted 56 days, Data on Feed and dry matter intake, Weight gain, concentrate/gain ratio, dressing percentage and carcass quality was collected. Investigations revealed that incorporating BNM in concentrate diets did not significantly (P>0,05) enhance dry matter intake (405, 416, 395 and 407g/day for diets A, B, C and D respectively), daily weight gain (27, 60, 23, and 42g/day for diets A, B, C and D respectively) concentrate /gain ratio (9.36, 5.62, 10.60 and 8.37 for diets A, B, C and D respectively). Dressing percentage differed significantly (P<0.05) among treatment groups and was higher for goats fed the BNM- based diets compared to the control and the values were 40.56, 43.28, 41.85 and 41.34%for diets A, B, C and D respectively. Meat cut values showed that leg. loin and shoulder of all the Jointed parts (Shoulder, leg. loin, sets and ends) were significantly different (P<0.05) among treatment groups. The values were 13.20, 13.56, 12.12 and 11.44 %; 12.38, 11.30, 13.19, 11.97 %; 13.60, 12.37, 10.91 and 11.31 % for goats on diets A, B, C and D for leg, loin and shoulder respectively. There was significant differences (P<0.05) among treatment means for all parts that constitute the offal (head, skin, feet, full gut and empty gut) except for empty gut. On the average Diet B comparatively, yielded lower offal weight. It can be concluded that goats fed Diet B (10% BNM performed better comparatively in terms of feed conversion ratio, dressing percentage and bone to lean ratio.

Background and Aim: In an era of increasing concerns about food availability globally, poultry meat is being increasingly consumed rather than red meat given its quality in terms of pH, color, and tenderness, conferring consumer satisfaction. The choice of feed is a crucial factor in poultry production. This study investigated the effect of dietary supplementation with breadfruit leaf powder on growth performance, meat quality, and antioxidative activity in Japanese quail. Materials and Methods: A total of 120 day-old quail were used in this study and assigned equally into four treatment groups: Group C fed a basal diet and three treatment groups fed a basal diet supplemented with 2.5% (T1), 5% (T2), or 10% (T3) breadfruit leaf powder. The concentrations of breadfruit leaf powder were 2.5, 5, and 10 g/kg in the basal diet. Quail body weight and feed intake (FI) were evaluated at 1, 21, and 35 days of age at 7 a.m. Pectoral muscle was collected to determine pH, meat color, drip loss, cooking loss, water-holding capacity (WHC), tenderness, and antioxidant levels. All variables were analyzed statistically using ANOVA followed by Duncan's post hoc test (significance set at p<0.05). Results: T3 showed increased body weight gain of quails at 1-21 and 21-35 days (p<0.05). Feeding in the T3 group improved the feed conversion ratio compared with those in the C and T1 groups at the starter phase (p<0.05). Dietary treatment did not affect FI (p>0.05). In the present study, meat redness and WHC were improved in the T3 group (p<0.05). Meanwhile, drip loss, cooking loss, and meat tenderness were improved in the T2 group (p<0.05). The pH45 min, pH24 h, lightness, and yellowness were not influenced by the treatments (p>0.05). The antioxidative activities of superoxide dismutase and malondialdehyde decreased in the T3 group (p<0.05), while no significant difference in glutathione peroxidase level (p>0.05) was identified. Conclusion: Ten grams/kilogram of breadfruit leaf powder, as administered in the T3 group, can be applied as a dietary supplement for Japanese quail to improve growth performance, meat quality, and antioxidative activity during the starter and grower periods.

Aims: The present investigation aimed at assessing the effects of feeding graded levels of DDGS with or without enzymes on the carcass characteristics of indigenous chicken. Study Design:  The experiment was conducted in a Completely Randomized Design (CRD). Place and Duration of Study: Department of Animal Nutrition, College of Veterinary Science, Guwahati-22, Assam for a period of 182 d (13 fortnights) between January 2018 and June 2018. Methodology: A total of 180 21 d old indigenous chicks were divided into six groups: T1, T2, T3, T4, T5 and T6 each with 30 chicks. The birds of T1, T3 and T5 were fed a basal diet containing 0, 10 and 20 per cent DDGS while the birds in T2, T4 and T6 were fed the same basal diet as that of T1, T3 and T5, respectively, but were additionally supplemented with a commercial exogenous multi-enzyme preparation. The feeding trial was conducted for a period of 182 d (13 fortnights) excluding a metabolic trial for a period of 8 days. At the end of the experiment, four birds from each treatment group were randomly selected, slaughtered and processed and different carcass traits viz. live weight, dressing percentage, relative weights of breast, thigh, drumsticks, liver, heart, gizzard, giblets, head and shank in relation to pre-slaughtered live weights were recorded. The chemical composition and organoleptic evaluation of meat samples from different treatment groups were also conducted. Results: The percent dressing and eviscerated yields of experimental birds under different treatment groups were ranged from 66.81±0.37 to 67.68±0.41 and 71.74±0.54 to 73.35±0.34, respectively. No significant (P ≥ .05) differences were observed in respect of relative weights of various carcass traits in relation to the live body weights, the chemical compositions of breast meat comprising of moisture, crude protein, ether extract and total ash and the mean scores for organoleptic evaluation comprising of colour, tenderness, flavor, juiciness and overall acceptance of the breast meat of experimental birds from different treatment groups. Conclusion: It is concluded that DDGS can be incorporated at 20% level in the rations of indigenous chicken for the economic gain without any adverse effect on dressing percentage as well as various carcass traits and organoleptic qualities.
