  • Short communication Evaluation of the use of Buddleia skutchii tree leaves and Kikuyu (Pennisetum clandestinum) grass hay in Sheep Feeding
    2020
    Co-Authors: J. Nahed, D. Grande, L. Sanginés, Germán Mendoza, F. Pérez-gil
    Abstract:

    Sixteen growing intact male Criollo Sheep, 19.9 ± 2.5 kg initial live weight, were randomly allocated to metabolic cages. Four treatments with four replications were evaluated. The treatments were: T1 = 100% Kikuyu (Pennisetum clandestinum) grass hay (KGH); T2 = 25% Buddleia skutchii leaves (BSL) + 75% KGH; T3 = 50% BSL + 50% KGH, and T4 = 75% BSL + 25% KGH. The highest ( P 0.05) and both were higher in comparison with the rest of the treatments. Digestibilities of dry matter (DM), crude protein (CP), NDF and acid detergent fibre (ADF) were not statistically different ( P> 0.05) for treatments T1, T2 and T3, and both T1 and T2 were significantly ( P 0.05). Nevertheless, there was a clear tendency in reduced DMI, digestibilities and DLWG when replacing KGH with 50 or 75% of BSL. In addition, a basic economic evaluation was carried out.

    Abstract Sixteen growing intact male Criollo Sheep, 19.9±2.5 kg initial live weight, were randomly allocated to metabolic cages. Four treatments with four replications were evaluated. The treatments were: T1=100% Kikuyu (Pennisetum clandestinum) grass hay (KGH); T2=25% Buddleia skutchii leaves (BSL)+75% KGH; T3=50% BSL+50% KGH, and T4=75% BSL+25% KGH. The highest (P 0.05) and both were higher in comparison with the rest of the treatments. Digestibilities of dry matter (DM), crude protein (CP), NDF and acid detergent fibre (ADF) were not statistically different (P>0.05) for treatments T1, T2 and T3, and both T1 and T2 were significantly (P 0.05). Nevertheless, there was a clear tendency in reduced DMI, digestibilities and DLWG when replacing KGH with 50 or 75% of BSL. In addition, a basic economic evaluation was carried out. The best net benefit (NB; US $1.01) and direct return rate (DRR; US $0.32) was for T1, but both NB and DRR were reduced for all levels of BSL inclusions.

    Abstract:

    Abstract The objective of this article is to offer some information about traditional practice regarding the use of the genus Buddleia in the Highlands of Chiapas, Mexico, with the aim of increasing its use as a potential fodder for Sheep Feeding in the area. Based on the indigenous Tzotzil Botanical Classification, three Buddleia groups were taxonomically identified. Group 1 includes the species Buddleia skutchii and Buddleia cordata, group 2, Buddleia americana and Buddleia crotonoides, and group 3, Buddleia parviflora and Buddleia nitida. Even though all these groups have been used as fodder, the most frequently used are the species in group 1, which are the most common species with the widest distribution patterns. Based on their chemical composition, the species of higher nutritional values were B. skutchii and B. crotonoides (crude protein (CP), 10.6% and 9.3%; neutral detergent fiber (NDF), 37.5% and 33.7%; in vitro dry matter digestibility (IVDMD), 75.9% and 58.2%; and digestible energy (DE), 3.3 and 2.5 Mcal/kg). The first one has been recommended for Sheep Feeding based on its high nutritional value. During an intake and digestibility trial, B. skutchii leaves substituted 50% of Kikuyo grass (Pennisetum clandestinum) without decreasing dry matter (DM) intake and digestibility. These results suggest that the systematic incorporation of B. skutchii into existing Sheep production systems could markedly increase feed resources without higher pressure on pasture land.

  • Evaluation of promissory tree species for Sheep Feeding in The Highlands of Chiapas, Mexico
    Animal Feed Science and Technology, 1998
    Co-Authors: J. Nahed, A Sánchez, D. Grande, F. Pérez-gil
    Abstract:

    Abstract The main objective of this study consisted of evaluating the fodder potential of the foliage of Buddleia cordata, Montanoa leucantha subsp. arborescens, Erythrina chiapasana, Quercus rugosa and Alnus acuminata var. arguta , tree species present in The Highlands of Chiapas, Mexico, in order to select the best fodder and carry out an evaluation of the species with greatest potential in Sheep Feeding. The chemical composition results on a dry matter basis were as follows: the crude protein (CP) content ranged from 8.4% in Q. rugosa to 27.7% in M. leucantha . Neutral detergent fiber (NDF) ranged from 39.0% in M. leucantha to 58.3% in Q. rugosa and Acid detergent fiber (ADF) varied from 30.8% in M. leucantha to 56.8% in Q. rugosa ; Gross energy (GE) contents were 3.0 kcal/g or even greater. Tannic acid was detected from 0.25 g/100 g in E. chiapasana to 1.1 g/100 g in Q. rugosa ; there were no cyanogenic glucosides detected in the samples, and no alkaloids were encountered in Q. rugosa and A. acuminata , but E. chiapasana showed higher alkaloid content than the other trees. Q. rugosa had the highest foliage production (6.9 kg DM/plant/cut), while E. chiapasana had the lowest production (1.2 kg DM/plant/cut). In an in vivo intake and digestibility trial, the leaves of M. leucantha fed as a sole diet for Sheep had the best composition values, higher ( P M. leucantha was included in the Sheep's diet in a growth and digestion trial at 0%, 25% and 40% levels of inclusion replacing alfalfa ( M. sativa ); in vivo CP intake (IVCPI-D) (106.9 g/day), in vivo CP digestibility (IVCPD-D) (67.5%), and live weight gain (LWG) (75 g/day) were higher ( P M. leucantha leaves at 40% level of inclusion. In vivo DM intake (IVDMI-D), in vivo DE intake (IVDEI-D) and in vivo NDF intake (IVNDFI-D), as well as in vivo DM digestibility (IVDMD-D), in vivo DE digestibility (IVDED-D), in vivo NDF digestibility (IVNDFD-D) and wool production (WP), were similar ( P >0.05) in diets including 0%, 25% and 40% of Montanoa leucantha leaves.

  • supplementation of graded levels of desmodium intortum hay to Sheep Feeding on maize stover harvested at three stages of maturity 1 feed intake digestibility and body weight change
    Animal Feed Science and Technology, 2000
    Co-Authors: Adugna Tolera, Frik Sundstol
    Abstract:

    Feed intake, digestibility and body weight change of lambs fed basal diets of maize stover harvested at three stages of maturity and supplemented with graded levels (0, 150, 300 and 450 g per head per day) of desmodium (Desmodium intortum cv. Greenleaf) hay were studied. The maize stovers were harvested at 30, 22 and 12% grain moisture content which were designated as stages I, II and III, respectively. The crude protein (CP) content of the stovers showed a decreasing trend whereas the fibre contents showed an increase from stages I to III. The desmodium hay had higher CP, phenolic compounds, calcium, sulphur and manganese contents and lower fibre (neutral and acid detergent fibres, cellulose and hemicellulose) contents than the stovers. Maize stover, total dry matter (DM) and organic matter (OM) intake showed a decreasing trend (p>0.05) with increasing stage of maturity of the stover. The CP intake was significantly higher (p 0.05) with increasing stage of maturity. Crude protein digestibility and the intakes of digestible

  • the potential of nematophagous fungi to control the free living stages of nematode parasites of Sheep Feeding and block studies with duddingtonia flagrans
    Veterinary Parasitology, 2001
    Co-Authors: P J Waller, M R Knox, M Faedo
    Abstract:

    Abstract A series of Feeding trials was conducted with penned Sheep harboring Trichostrongylus colubriformis infections. They were offered barley grains supporting the growth of the nematophagous fungus Duddingtonia flagrans. It was shown that as little as 5 g of grain/Sheep per day was sufficient to virtually eliminate larval numbers from faecal culture. This effect persisted for the time that the fungal grains were fed, and for up to 2 days following cessation of Feeding this material. Macerated fungal grains were also incorporated into a range of feed block formulations. In all these, D. flagrans was found to survive the manufacturing process and resulted in significant reductions in larval numbers in faecal cultures set up during the Feeding period to Sheep. This was observed even for Sheep that showed only modest and irregular block consumption. These studies demonstrate that supplementary Feeding or block administration offer potential deployment options for D. flagrans as a means of biological control of nematode parasites of livestock.
