Feeding Aquilaria sinensis Leaves Modulates Lipid Metabolism and Improves the Meat Quality of Goats. Foods 2023; 12:foods12030560. [PMID: 36766087 PMCID: PMC9914005 DOI: 10.3390/foods12030560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 01/19/2023] [Accepted: 01/21/2023] [Indexed: 02/03/2023] Open
Abstract
Aquilaria (A.) sinensis is a medicinal plant widely grown in tropical South China. Given the abundant pruning waste of its leaves, the use of A. sinensis leaves is valuable. In this study, goats were fed a diet containing 20% A. sinensis leaves. Compared with the basal diet, feeding A. sinensis leaves to goats did not affect growth performance but considerably reduced the feeding cost. Strikingly, feeding A. sinensis leaves resulted in a significant decrease in the blood cholesterol levels (2.11 vs. 1.49 mmol/L, p = 0.01) along with a significant increase in the high-density lipoprotein levels (1.42 vs. 1.82 mmol/L, p = 0.01). There was also a tendency to lower the content of low-density lipoprotein levels in goats (0.78 vs. 0.45 mmol/L, p = 0.09). Furthermore, metabolomics analysis demonstrated that the reduction in cholesterol levels occurred in both the serum (0.387-fold change) and muscle (0.382-fold change) of goats during A. sinensis leaf feeding. The metabolic responses to feeding A. sinensis leaves suggest that the activation of lipolysis metabolism might happen in goats. These observed changes would be conducive to improving animal health and meat quality, ultimately benefiting human health.

Abstract
The objective of this study was to evaluate the effects of diet and age on finishing performances and carcass characteristics of male Creole goats. A total of 91 weaned male Creole kids [84 days old ± 7 days, 9.2 kg live weight (LW) ± 0.5 kg] were randomly allocated in a 2 × 3 experimental design. The animals were fed individually with two diets: C0: a 28-day-old Digitaria decubens grass alone, or C50: the same grass plus a commercial concentrate (50% of the total diet) and then slaughtered at 7, 11, or 15 months of age. Significant feeding regimen and age at slaughter effects were observed on the goat carcass characteristics. The addition of concentrate improved the average daily gain (ADG), the dressing percentage, and the conformation score (1-5 scale) from 46 to 88 g/day, 52.8 to 62.4%, and 2.2 to 4.9, respectively. Moreover, carcasses of the C0 group appeared lean with less developed fat than the C50 group and lighter than visceral fat. The meat color was significantly more affected by diet than age. Our data suggested that the production of heavy carcasses with low proportions of fat in the meat is possible in this local breed. The valorization of such a forage feeding system until 11 months of age or with the addition of concentrate from 7 to 11 months of age should be evaluated economically.

Abstract
An experiment was planned to explore the possibilities of replacement of concentrate mixture by Hedge lucerne (Desmanthus virgatus) in growing Osmanabadi goats for 90 days. Osmanabadi growing goats (18) of either sex with similar age and body weights (12.77±0.53 kg) were divided into two treatment groups and one control group (T0) with six goats in each group. Concentrate mixture was offered to control group (T0), while T1 and T2 groups received ration in which 50% and 100% concentrate was replaced by Hedge lucerne on dry matter basis. The mean fortnightly dry matter intake (g/d) was significantly higher in control (T0) and T2 than T1. The intake of DCP (g/d) was significantly higher in control and T1 as compared to T2. The per cent digestibility of nutrients namely DM, OM, CP, EE, CF and NFE did not differ significantly amongst the treatment groups. Total gain in body weight (kg) was significantly higher in T1 (2.71±0.13) as compared to T0 (2.58±0.50) and T2 (2.25±0.02). The final body weight of experimental goats were 15.57 kg (T0), 15.18 kg (T1) and 15.61 kg (T2) respectively. The body condition score was significantly higher in T0 and T1 than T2. The total cost of production was significantly higher in T0 (` 1858.86) followed by T1 (` 1810.81) and T2 (` 1725.85). The highest net profit per goat was recorded for T2 (` 2957.15), followed by T0 (` 2812.14) and T1 (` 2743.15) groups. It is concluded that inclusion up to 50% Hedge lucerne to replace concentrate in diet of goats improves growth performance and increases net profit of Osmanabadi goat production.

Abstract
The objective of this study was to evaluate carcass characteristics, meat quality, and organ and viscera weight of forty male sheep, not castrated, initially weighed 26.5 ± 1.85 kg, and confined for 100 days (44 days for the adjustment period and 56 days of the experimental period). The treatments were four levels of replacement of Bermuda grass hay with alfalfa hay (0, 200, 400, and 600 g/kg, based on dry matter). The design was randomized blocks (one lighter group and other heavier group) with 10 animals in each treatment. There were no effects on weight gain or carcass parameters. However, an increase was observed on dry matter intake (g/day), crude protein intake (g/day), empty body weight (kg), and subcutaneous fat thickness (mm). There was also an increase in total organ weights in kg and g/kg. The tissue composition of the leg had a quadratic effect on the bone tissue weight (g) and linear effect on adipose tissue relative (g/kg) and muscle-fat relations. There was also a quadratic effect on bone tissues (g/kg) and muscle-bone relations. Likewise, there was a quadratic effect on the qualitative characteristics of meat (measure of luminosity), with the replacement of Bermuda grass hay with alfalfa hay in sheep feed. The replacement of Bermuda grass hay with alfalfa did not change carcass characteristics and meat quality.

Abstract
The effects of corn replacement by cassava dreg in diets of crossbred goat kids were evaluated. We tested the impacts of 0, 33, 66 and 100% replacement on intake, digestibility, feeding behaviour, performance and carcass characteristics. Thirty-six goat kids, aged between 4 and 5 months and with initial body weights of 17.61 ± 1.98 kg, were used in a completely randomised design. Analysis of regression revealed a negative linear effect on neutral detergent fibre (NDF) intake and a positive linear effect on non-fibrous carbohydrates (NFC) and hydrocyanic acids (HCN) intake. Cassava dreg use had a positive linear effect on organic matter digestibility and non-fibrous carbohydrates. Based on our results, cassava dreg use did not negatively impact animal performance, feeding behaviour and carcass characteristics, suggesting that it may replace corn up to 100% in the diets of confined goat kids.

Hailemariam S, Urge M, Menkir S. Effect of feeding Neem (Azadirachta indica) and Acacia (Acacia senegal) tree foliage on nutritional and carcass parameters in short-eared Somali goats. Trop Anim Health Prod 2015; 48:461-4.

Abstract
The study was conducted to determine the effects of dried foliage of Acacia senegal and Neem (Azadirachta indica) tree supplementations on feed intake, nutrient digestibility, growth, and carcass parameters in short-eared Somali goats. Twenty male intact short-eared Somali goat yearlings with an average live weight of 16.2 ± 1.08 (Mean ± SD) were assigned to four treatment groups, which comprised a basal diet of hay alone (T1) and supplementation with the tree foliages. Supplements consisted Neem tree (T2), A. senegal (T3) and the mixture of the two (1:1 ratio; T4) dried foliages. The crude protein (CP) content of Neem tree foliage, A. senegal, and their mixture were 16.92, 17.5 and 17.01 % of dry matter (DM), respectively. Total DM intake and digestibility of DM and organic matter were significantly (P < 0.001) higher for the supplemented groups. CP digestibility was significantly higher (P < 0.01) for goats supplemented with Neem tree (72 %) and A. senegal (67 %). The final body weights were higher (P < 0.05) for the goats supplemented with A. Senegal. An average daily body weight (BW) gain was higher (P < 0.01) in supplemented groups. The hot carcass weight was higher in the group supplemented with A. senegal (8.3 kg) among the supplemented groups, all of which are higher than the control (4.9 kg). It is concluded that the supplementation with tree foliage, especially with A. senegal tree foliage, on grass hay encouraged a better utilization of nutrients and animal performance as compared to goats fed on a basal diet of grass hay only.

Abstract
The objective of the study was to determine the effect of supplementing Moringa oleifera leaves (MOL) on growth performance, carcass and non-carcass characteristics of crossbred Xhosa lop-eared goats. A total of 24 castrated goats aged 8 months, with a mean initial weight of 15.1 ± 2.3 kg, were randomly divided into three diet groups with eight goats in each. The duration of the trial was 60 days. All goats received a basal diet of grass hay (GH) ad libitum and wheat bran (200 g/day each). The MOL and sunflower cake (SC) groups were fed additional 200 g of dried M. oleifera leaves and 170 g of SC, respectively. The third group (GH) did not receive any additional ration. The crude protein of MOL (23.75%) and SC (23.27%) were higher (P < 0.05) than that of the GH diet (14.08%). The attained average daily weight gain for goats fed MOL, SC and GH were 103.3, 101.3 and 43.3 g, respectively (P < 0.05). Higher (P < 0.05) feed intakes observed were in SC (491.5 g) and MOL (490.75 g) compared with GH (404.5 g). The hot carcass weight was higher (P < 0.05) for SC (10.48 kg) and MOL (10.34 kg) than for the GH group (8.59 kg). The dressing percentage in SC (55.8%) and MOL (55.1%) were higher (P < 0.05) than that of the GH (52.9%). The growth performance and carcass characteristics of SC and MOL goats were not different. Feeding MOL or SC improved the growth performance and carcass characteristics of goats in an almost similar way, which indicates that M. oleifera could be used as an alternative protein supplement in goats.

Abstract
Carcass data base of 164 Creole male goats was used in order to provide factual data on the carcass conformation. Standardised procedures of carcass measuring and cutting were followed. The European official grid of light lamb is implemented for meat goat in the French West Indies and included five levels. Weights of carcass, cuts and tissues, quality scores and linear measurements were analysed. Feeding system, age at slaughter and weight were taken into account for statistical analysis. There were significant differences among carcass conformation classes (CC) for many traits except for the fat score, leg length and compactness ratio (carcass width on length): 2.2, 34.5 cm and 0.30 on average, respectively. The values of chilled carcass weight and yield and the carcass linear measurements steadily increased until conformation class 4 or 5: 6.7 to 11.2 kg, 49% to 55% and 52.4 to 58.0 cm carcass length. For the weights of carcass cuts, significant differences appeared between two groups: classes 1 and 2 vs. classes 3, 4 and 5. Regardless of the carcass weight, the distribution of prime cuts remained similar. The indices calculated on a weight basis (kg/cm), either for the carcass or the leg, increased significantly (P<0.01): with 54% and 63% difference between the two extreme classes, respectively. The muscle, bone and fat proportions in the shoulder did not vary between CC with 0.72, 0.22 and 0.06, respectively. Corresponding traits in leg were 0.74, 0.23 and 0.03; the last two were different (P<0.05) from class 1 to class 5. The muscle/bone ratios calculated either in shoulder or in leg ranged from 3.1 to 3.6 (P>0.05).

Abstract
Studies were conducted to determine the effects of feeding regimens on growth and carcass quality of the Creole goat, a genotype indigenous to the Caribbean. Forty kids weighing 9.0 +/- 1.2 kg of BW were reared indoors after weaning. Four supplement amounts were compared (10 kids per treatment): the G0 group received the basal diet (tropical forage, 8.8 MJ of ME and 108 g of CP/kg of DM) without concentrate, whereas the G100, G200, and G300 groups were offered 130, 230, and 310 g/d of concentrate (13.6 MJ of ME and 209 g of CP/kg of DM), respectively, in addition to the basal diet. The kids were slaughtered according to the standard procedure at 22 to 24 kg of BW for assessment of carcass traits and meat quality. Total DMI increased significantly, from 51 to 78 g/kg of BW(0.75), for G0 to G300 kids, whereas their ADG doubled from 42 to 84 g/d (P < 0.01; P < 0.01, respectively). The G:F values reached 125 to 130 for the G200 and G300 diets and were satisfactory compared with literature values. The carcass weight and dressing percentage (P < 0.01) increased from group G0 to G300, from 9 to 13 kg and from 42 to 51%, respectively. The proportions of the different cuts (related to the carcass weight) did not vary by diet. The conformation score increased significantly (P < 0.05) among the 4 groups from an average score of 3.2 to 4.0 (score/5). There was a significant effect (P < 0.01) of supplement amount on the accumulation of internal fat tissues: the kidney fat weight increased from 113 to 253 g from the G0 to the G300 group. Regardless of the feeding level and amount of internal fat, the carcasses had an acceptable fat cover score, which remained less than 2.6 (score/5). A significant effect was not observed for the ultimate pH and the main color variables of the meat. The cooking loss and the shoulder DM content varied (P < 0.05) with the supplement amount. By increasing the nutritional density of the diet, it was possible to obtain well-conformed and heavy carcasses, with no excessive fattening. Indigenous Creole goats have potential as meat animals when fed to gain more than 80 g/d. The optimal supplement supply with good-quality grass would be approximately 3.69 MJ of ME/d in our conditions. Further studies are required on meat sensory parameters and fatty acid profiles.
