“…In general, consumers prefer meat with less fat [32]. Carcass fat percentage in this study (17.61%) was similar to those reported by Santos et al [21] (i.e., 15-18%) and Obeidat et al [27] (i.e., 16.6-20.1%). Lambs with lighter body weight than mutton contain less carcass fat trimming, as reported by Sabbioni et al [25] who found that lamb fat trimmings were 13.04-17.31%, whereas those in mutton were 15.96-19.06%.…”

“…Meat-bone ratio is an important parameter because it is related to the edible portion of the carcass. The meat-bone ratio in this study (3.67) was higher than that in Awassi lambs fed up to 300 g/kg layer litter (2.95-3.10) [27], Cornigliese lambs (2.22-3.09), and mutton (3.25-3.52) [25]. The lean meat-bone ratio in this study (2.84) was lower than that reported by Ekiz et al [33] (3.13-3.48).…”

“…The carcass weights obtained in this study were similar to those reported by Setyaningrum et al [26], where Indonesian thin-tailed sheep weighing 17.5-18.8 kg produced 7.7-8.5 kg carcasses. Other studies reported that lamb carcass weights varied from 15.3 kg to 26.1 kg when originating from a slaughter weight of 34.3 kg-54.1 kg [21,[27][28][29][30]. Forwood et al [30] reported that heavier live weights produced higher carcass weights and dressing percentages.…”

Background and Aim: Grass is often scarce for ruminants during the dry season in Indonesia; thus agricultural by-products are widely used as a substitute for grass. This study aimed to determine the effect of replacing Napier grass (NG) with agricultural by-products on the productivity and carcass characteristics of lambs. Materials and Methods: Twenty-four 3-month-old male lambs with initial body weights of 13.26±1.29 kg (coefficient of variation=9.73%) were allocated into a completely randomized design with four treatments and six replications. The treatments included: NG=100% NG; corn cobs (CCs)=50% NG and 50% CCs; bagasse (BG)=50% NG and 50% BG; and peanut shells (PSs)=50% NG and 50% PSs. All treatment diets were pelleted and consisted of 40% fibrous feed and 60% concentrate feed, and contained 10.36-11.65% crude protein and 55.47-57.31% total digestible nutrients. Parameters observed included dry matter intake (DMI), dry matter digestibility, body weight gain (BWG), feed conversion ratio (FCR), feed cost per gain (FC/G), and carcass characteristics. Results: Lambs fed the PSs diet had the highest (p<0.05) DMI (781 g/d), digestibility, and body weight gain (92.5 g/d; p<0.05). The FCR of the PSs diet (9.13) was similar to NG. The FC/G of the PSs diet (IDR 23,541/kg) was the lowest of all diets. The BG diet had the lowest (p<0.05) digestibility, body weight gain (54.4 g/d), and the highest (13.53) FCR. No significant differences (p>0.05) were found in the carcass or meat characteristics of any diets. The averages of slaughter weight, carcass weight, and carcass percentage were 20.03 kg, 8.02 kg, and 40.0%, respectively. The average meat bone ratio was 3.67. Conclusion: It was concluded that agricultural wastes could be used as an alternative to NG at the level of 50% in the diet of lambs without a negative effect on production performance and carcass traits.

As the byproduct of finger millet, millet straw is a new forage resource of ruminants. The effect of the combined utilization of millet straw with corn straw on fattening lamb production is seldom reported. The purpose of this study was to investigate the effect of different proportions of millet straw instead of corn straw on the growth performance, blood metabolites, immune response, meat yield, and quality of fattening lamb. Sixty-three-month-old healthy Small-Tailed Han sheep crossbred rams with an average initial weight of 19.28 ± 2.95 kg were randomly divided into four groups, with three replicates in each group and five lambs in each replicate. The replacement ratio of millet straw of each group (Group I, II, III, IV) was 0%, 25%, 35%, 50% at the first stage (the first two months) and 0%, 20%, 28%, 40% in the second period (final two months), respectively. The experiment lasted 4 months 10 days of the pre-feeding period. The results indicated that the body weight gain and average daily gain of group Ⅱ were significantly higher than those of group Ⅰ and group Ⅳ (p < 0.05). The concentration of total protein in group Ⅳ was significantly increased compared to those of the other three groups at the second stage (p < 0.05), which proved that the protein synthesis metabolism capacity was improved with the addition of millet straw. The concentration of the plasma glutamic-oxalacetic transaminase and lactic dehydrogenase of lambs was significantly decreased in group Ⅱ (p < 0.05). The combination of millet straw and corn straw had no impact on the glucose, total cholesterol, and triglycerides metabolism (p > 0.05). There was no significant difference in the pre-slaughter weight, carcass weight, dressing percentage, loin-eye area, and GR value among the four groups (p > 0.05). Furthermore, the immune response and meat quality were not impacted by the different proportions of millet and corn forage diets. The results showed that the combined utilization of millet straw with corn straw could improve the blood biochemistry metabolism capability of fattening lambs. The replacement of 50% of corn straw with millet straw could improve the growth performance and be an application in fattening lamb production.

“…The neutral detergent fibre (NDF) and acid detergent fibre (ADF) of feed were measured according to Van Soest et al (1991). Total phosphorus of feed Obeidat et al (2019), and the averages were used in the statistical analysis. The longissimus dorsi samples were cut into blocks and weighed before and after cooking in a plastic bag in an 80 °C water bath for 1 h, and cooking loss was calculated and recorded.…”

This experiment aims to study the effects of dietary fat level during the suckling period on growth performance and meat characteristics in twin lambs. Thirty pairs of male twin Hu lambs were divided into two groups, namely high fat (HF) and normal fat (NF). Lambs in HF group were fed milk replacer and starter containing 26.89% and 5.07% of fat, whereas those in NF group, were fed milk replacer and starter containing 15.15% and 2.80% of fat, respectively, from eight to 60 days of age. From 60 to 120 days of age, all lambs were fed a starter feed containing 2.80% fat. The results showed that lambs fed HF diet had higher body weight (12.78 kg versus 11.63 kg, P = 0.020), average daily gain (162.4 g/day versus 141.1 g/day, P = 0.019), apparent digestibility of organic matter (P = 0.018) and gross energy (P < 0.001). No difference was observed between HF and NF group in slaughter performance during eight to 60 days of age. Lambs fed HF diet had higher body weight at 120 days of age (P = 0.035). However, no difference was observed in nutrient digestibility, slaughter performance or meat quality at 120 days of age. In summary, HF diet in the suckling period showed long-lasting beneficial effects on the growth performance
