PROCESSED PIG'S SLAUGHTER HOUSE OFFAL. CHEMICAL COMPOSITION

Herrera, R., Instituto de Investigaciones Porcinas. Gaveta Postal No. 1, Punta Brava. La Habana et al. [2001]

The chemical composition of 48 representative samples from processed pig's slaughter house residues or offal from a slaughter house in Havana City was examined. The samples were from batch obtained daily and then mixed proportionally to obtain a threeday pooled sample. Sampling was carried out during the first five months of operation of the slaughter house (from February to June 1999) and the ...

A NOTE ON THE CHEMICAL COMPOSITION OF FOLIAGE FROM TWO VARIETIES OF CLITORIA TERNATEA L.

López, J.L., Centro de Investigaciones en Bioalimentos Carretera Patria km 1½ Morón, CP 67210, Ciego de Avila et al. [2001]

A study was conducted on the chemical composition and gross energy content in the foliage from the varieties SN-139 and Tehuana of Clitoria ternatea L. The organic matter concentration (92.0; 91.1%) and crude protein content (20.1; 18.7%) were significantly (P0.01) higher in the local Cuban variety SN-139 as compared to Tehuana, while there were not significant differences between both cultiva ...

STUDIES ON IN VITRO (PEPSIN/PANCREATIN) DIGESTIBILITY OF TROPICAL TREE FOLIAGE FOR FEEDING PIGS

Díaz, C., Instituto de Investigaciones Porcinas Gaveta Postal No.1 et al. [2001]

The chemical composition and in vitro digestibility (IVD, pepsin/pancreatin) of foliages from carob (Albizia lebbek), gliricidia (Gliricidia sepium), guásima (Guazuma ulmifolia), hibiscus (Hibiscus rosa-sinensis) and mulberry (Morus alba) were determined. Overall, IVD of DM and organic matter was in the range of 30.6-48.0% and 33.3-46.7% respectively. The range for IVD of N was rather higher, ...

A STUDY ON THE CHEMICAL COMPOSITION OF SUGAR CANE MOLASSES TYPE B FROM A CUBAN SUGAR FACTORY

Macías, M., Instituto de Investigaciones Porcinas. Gaveta Postal No. 1, Punta Brava. La Habana et al. [2001]

Chemical indices were determined in representative samples of 7000 t of sugar cane molasses type B produced in a sugar cane mill in Matanzas province, between February and April 2001. These indicators were determined to study the variation of molasses components and to fulfill the quality parameters agreed between the sugar manufacturing enterprise and pig producers for the industrial process. ...

ON THE NUTRITIVE VALUE OF FOUR FRESH WATER FISH SPECIES

García, M.D., Instituto de Investigaciones Porcinas. Gaveta Postal No. 1, Punta Brava. La Habana et al. [2000]

The nutrient content and in vitro digestibility of organic matter and nitrogen were studied in four fresh water fish species: tilapia (T, Oreochomis niloticus), silver carp (SC, Arichthistys nobilis), bighead carp (BC, ypophtaimichtys molitrix) and grass carp (GC, Ctenofaringodon idellum), raised in semi-intensive polyculture in Cuba. The crude protein content (Nx6.25, % DM) of GC was 64.6, si ...

Se estudió la digestibilidad total en 9 cerdos Yorkshire machos castrados de 35 kg que fueron distribuidos al azar en tres dietas. La fuente de energía (57.9%) fue almidón de maíz, sacarosa o miel final de caña. La miel final disminuyó significativamente (P0.001) la digestibilidad total de MS, materia orgánica, energía y N. No hubo diferencias en los valores de digestibilidad entre las dietas ...

CHEMICAL COMPOSITION OF TWO SPECIES OF EARTHWORMS (EISENIA FOETIDA Y EUDRILUS EUGENIAE) OBTAINED TO PIG MANURE

García, M.D., Instituto de Investigaciones Porcinas. Gaveta Postal No. 1, Punta Brava. La Habana et al. [1997]

The chemical composition and nitrogen content were studied in representative samples from six batches of two earthworms species (Eisenia foetida and Eudrilus eugeniae) freeze dried. Dry matter mean (%) and crude protein content (% DM) were: 20.44 and 62.13; 22.40 and 58.87, respectively. The ash content (% DM) was different (P0.01) between the species: 10.94 and 13.68, respectively. The other ...

CHEMICAL COMPOSITION OF PLANTAIN FOLIAGE MEAL (MUSA PARADISIACA)

García, A., Instituto de Investigaciones Porcinas. Gaveta Postal No. 1, Punta Brava. La Habana [1996]

The chemical composition and energy content were studied in representative samples from six batches of plantain foliage (Musa paradisiaca) grounded and sun-dried. Plantain foliage residues (RPF) were composed of l eaves and the higher third of the pseudostem. Mean dry matter and energy contents were 92.76% and 16.39 KJ/g DM. Nutrient content was: 12.79 ash; 3.80 ether extract; 1.56 N; 1.26 alp ...

THE EFFECT OF AGE OF WEANING ON THE POST-WEANING PERFORMANCE OF PIGLETS UNDER A TROPICAL ENVIRONMENT

Segura, J.C., Faculty of Veterinary Medicine and Animal Science, Autonomous University of Yucatán, Mérida et al. [2005]

Two experiments were conducted to determine the effect of age at weaning on the performance of piglets. In each experiment 240 pigs were weaned at either 2 or 3 week of age ad their performance was measured up to 70 days of age. In experiment 1, there were not significant (P0.05) differences from weaning to 28 days of age in body weight gain or feed consumption for piglets weaned at 14 or 21 d ...
