“…However animals on poor feed are forced to fill their gut with less digestible roughage and have proportionally bigger gut content. This result was also in agreement with the views of Vansoest (1994) and Pond et al (1995).…”

The experiment was carried out at Mekelle University livestock farm, Tigray, Ethiopia. Twenty four male yearling Highland sheep with an average live weight of 162.4kg (mean  standard deviation) were used in the experiment. The objective of the study was to investigate the effect of concentrate supplementation with mixtures of wheat bran (75%) and cotton seed cake (25%) on performance of highland sheep. The experimental design was a randomized complete Block design (RCBD) with four treatments and six replications. The experiment was carried out for 90 days after 21 days of feed adaptation period. At the end of the feeding trial digestibility trial was carried out for seven consecutive days followed by evaluation of carcass parameters. There was significantly higher (P<0.05) total DM intake in the supplemented group than the control treatment. Similarly, there was a significant difference (P<0.05) among all treatments in CP intake due to the increased level of supplementation. Digestibility of DM, OM and CP were also significantly higher (P<0.05) for rams supplemented with the higher level of concentrate mixture than the control treatment. The feed conversion efficiency was significantly (P<0.05) higher for the high level of supplement as compared to the other treatments. The mean values of slaughter weight, empty body weight and rib-eye area were significantly (P<0.05) higher for the 200 and 250 g/d supplemented treatments than the control Generally the present study indicated that supplementation of Tigray highland rams with concentrate mixture had an effect on performance of sheep and the effects were relatively more pronounced on rams supplemented with the highest level of concentrate mixture. Therefore, supplementation of WS with 250g DM concentrate mixture is biologically more efficient.

Effect of four processed animal proteins in the diet on digestibility and performance in laying hens

et al. 2010

An experiment was performed to investigate the effect of animal vs. vegetable protein sources in the diet of laying hens on the development of hen performance. A diet containing protein sources of only vegetable origin was compared with 4 diets, each containing 1 of 4 processed animal proteins (PAP). Two PAP (Daka-58 and Sonac-60) were classified as meat meals, and the remaining 2 (Daka-40 and Sonac-50) were classified as meat and bone meals. First, fecal digestibility of nutrients in the PAP was determined in Lohmann Brown layers. Hens (n = 132) were housed in 22 cages (6 hens/cage) and allotted to 5 dietary treatments. In the PAP diets (4 replicates/treatment), 100 g/kg of CP of animal origin was added, replacing soybean meal and corn (Zea mays) in the basal diet (6 replicates/treatment). The PAP sources differed largely in chemical composition and digestibility coefficients. Energy content (AME(n)) varied from 1,817 (Daka-40) to 3,107 kcal/kg (Sonac-60), and digestible lysine varied from 15.4 (Daka-40) to 28.3 g/kg (Sonac-50). Subsequently, the effect of a control diet (without PAP) vs. 4 PAP diets (50 g/kg of CP of animal origin from the same batches as used in the digestibility study) on performance was determined. All diets were isocaloric (AME(n) = 2,825 kcal/kg) and isonitrogenous (digestible lysine = 6.8 g/kg). Hens were housed in 40 floor pens (12 hens/pen, 8 pens/treatment) from 20 to 40 wk of age. Feed intake levels of the hens fed the meat and bone meal diets were reduced compared with those of hens fed the meat meal diets, whereas the feed intake level of hens fed the control diet was intermediate. Laying hen performance differed between treatments, being was most favorable for the Sonac-50 treatment and most adverse for the Daka-40 treatment. Differences in laying hen performance seemed to be related partly to differences in feed intake and corresponding amino acid intake.

The trial was conducted to investigate effect of hydrolyzed render meal and skin derived protein meal on the egg production performance, eggshell quality, egg quality and blood characteristics in laying hens. A total of 280 44 week (wk) old (Hy-Line brown) laying hens were used in this 6-wk trial. Birds were randomly assigned to 1 of 4 treatments, 1) BD, basal diet; 2) HRM, basal diet with 2% hydrolyzed render meal; 3) SSM, basal diet with 2% swine skin meal; 4) CHM, basal diet with 2% cattle hide meal with 14 replications per treatment and 5 adjacent cages as replications. During wk-44 to 46, the egg production (%) was significantly higher (P < 0.05) in SSM treatment (96.37 and 97.10) than others. Overall, egg production was higher (P < 0.05) in SSM treatment (96.79%) than CHM, HRM and BD treatments (96.16%, 95.90% and 95.30%) respectively. In case of average daily feed intake (ADFI), SSM showed significant higher (P < 0.05) value (120g) than BD treatment (117 g). Both SSM and CHM treatments seemed higher (1.009) egg gravity than BD treatment (p < 0.05) at 50-wk. On the other hand, at the same time, egg weight was significantly higher (P < 0.05) in BD treatment compared to others. The egg quality and blood characteristics were unaffected (p > 0.05) by dietary treatments. In a nut shell, the skin derived protein meal supplemented in laying hen diet at 2% enhanced the egg production performance of laying hens and inoffensive to the egg quality and laying hen health status.
