EVALUATION OF VIVARIUM ESTABLISHMENT OF TROPICAL TREES FOR SILVOPASTORIL PURPOSES IN THE MEXICAN STATE OF NAYARIT

Ramos Quirarte, A., Universidad Autónoma de Nayarit, Ciudad de la Cultura Amado Nervo s/n, Tepic. Nayarit et al. [2011]

Seeds from 22 arboreal species were examined in order to evaluate the initial vigor and growth of those trees to be used in silvopastoril systems. The seeds were scarified and sown in black plastic bags distributed according to a one-way design into 22 treatments with five bags per treatment and eight replications. Treatments were the different species of trees. The evaluated variables were ge ...

DESIGN AND EVALUATION OF A TUNNEL TYPE BIODIGESTER

Chao, R., Instituto de Investigaciones Porcinas. Gaveta Postal No. 1, Punta Brava. La Habana et al. [2011]

A tunnel biodigester with 3.3 m3of digestion volume and 2 m3 of biogas storage was designed, built and tested. The biodigestor construction was carried out with a dig into the ground, near a pig house which supplied pig manure to fed the biodigestor. The decrease in total solids, volatile solids and chemical oxygen demand were 69, 74 and 74% respectively, which agrees with obtained results in ...

USE OF KING GRASS (Penisetum purpureum) FRESH FORAGE IN DIETS WITH SUGAR CANE MOLASSES TYPE B FOR FEEDING GROWING-FINISHING PIGS

Piloto, J.L., Instituto de Investigaciones Porcinas. Gaveta Postal No. 1, Punta Brava. La Habana et al. [2011]

One hundred castrated male pigs of 25.0 kg live weight, 58 CC21 and 42 Duroc individuals were used. The animals were allotted at random into two treatments to study the effect of king grass (Penisetum purpureum) introduction in diets based on a protein, vitamin and mineral concentrate (nuprovim 75) and sugar cane molasses type B. Treatments consisted of a control diet where nuprovim 75 and sug ...

IN VITRO TECHNIQUES TO DESCRIBE ENERGY DIGESTIBILITY AND KINETICS OF CARBOHYDRATE DEGRADATION OF FEEDSTUFFS IN PIGS

Zijlstra, R. T., Department of Agricultural, Food and Nutritional Science.University of Alberta, Edmonton, AB T6G 2P5 et al. [2011]

Las técnicas in vitro puede describir la digestibilidad de la energía y la cinética de la digestión del almidón y la fermentación de la fibra de comidas para cerdos. Estas técnicas que mimetizan las condiciones en el tracto gastrointestinal tienen ventajas comparadas con los modelos de digestión in vivo. En primer lugar, se requiere menos material de muestra. En segundo lugar, los análisis pue ...

IN VITRO TECHNIQUES TO DESCRIBE ENERGY DIGESTIBILITY AND KINETICS OF CARBOHYDRATE DEGRADATION OF FEEDSTUFFS IN PIGS

Zijlstra, R.T, Department of Agricultural, Food and Nutritional Science. University of Alberta, Edmonton, AB T6G 2P5 et al. [2011]

In vitro techniques can describe energy digestibility and kinetics of starch digestion and fiber fermentation of feedstuffs in pigs. These techniques that mimic the conditions in the gastro-intestinal tract have advantages compared to in vivo models of digestion. First, less sample material is required. Second, the analysis can be conducted in less time. Third, the in vitro analysis is cheaper ...

EFFECT OF PHYTASE SUPPLEMENTATION TO DIETS FOR FINISHING PIGS

García, R., Universidad Autónoma Agraria Antonio Narro. Calzada Antonio Narro No. 1923, Colonia Buenavista. Saltillo, Coahuila et al. [2011]

Forty six animals, 20 females and 26 male pigs, of a commercial breed (Yorkshire, Hampshire, Duroc and Landrace) with a similar age and 43 kg initial live weight were assigned to two treatments consisting on a feedstuff without or with phytase (5 000 FTU) at a rate of 100 g/t to study productive traits during the finishing stage of 54 days. The diet contained 16.3% of crude protein (Nx6.25) an ...

NOTES ON THE ACCEPTABILITY AND PATTERN OF FEED INTAKE ON PIGS FEEDING BALANCED COMMERCIAL FEED

Díaz, C, Instituto de Investigaciones Porcinas. Gaveta Postal No. 1, Punta Brava. La Habana et al. [2011]

The acceptability and pattern of feed intake of different feed mixtures were determined in six pigs hybrid barrows with an average weight of 21 kg. The pigs were distributed according to a 3 x 3 Latin square design into three treatments. The treatments were the different mixtures of feed used (Cuban, Mexican and a Mexican pelletized mixture). Feed intake was restricted to 0.8 kg DM per kg0.75/ ...

A COMPARISON OF METHODS FOR DETERMINING RECTAL DIGESTIBILITY IN PELON MEXICANO PIGS

Grageola, F., Universidad Autónoma de Nayarit. Ciudad de la Cultura Amado Nervo. Tepic. Nayarit et al. [2011]

The direct and indirect methods for measuring rectal digestibility was compared in eight growing pigs, either improved, Yorkshire x Landrace, or local, Pelón Mexicano animals, according to a change over design in 2 x 2 arrangement. The direct method consisted in the the quantitative recording during five days of feed intake and faecal excretion whereas the indirect method was achieved by means ...

ILEAL AND FAECAL OUTPUT OF MATERIALS IN PIGS FED GRADED LEVELS OF SWEET POTATO FOLIAGE IN THE DIET

González, C., Facultad de Agronomía, Universidad Central de Venezuela. El Limón, Maracay et al. [2011]

Two experiments were conducted according to a 4x4 Latin square design for determining the ileal and rectal output of materials in crossbred castrated male growing pigs fed with graded levels (0, 10, 20 and 30% in dry basis) of sweet potato (Ipomoea batatas (L.) Lam) foliage meal. In experiment 1, four castrated male averaging 35 kg live weight were utilized and were prepared with an ileo-recta ...

Four representative samples from either mulberry (Morus alba) or trichanthera (Trichanthera gigantea) leaf meals were examined. The samples were obtained at random from periodical harvested foliages in plantations located at Maracay, Venezuela. Several indices related to foliage physico-chemical composition and in vitro, either by the pepsin/pancreatin or faecal incubation values, were determi ...
