SUMMARY Twenty four French Alpine goats (39 ± 2·0 kg) were individually housed in a completely randomized design and fed basal diet containing 146 g crude protein 356 neutral detergent fibre (NDF)/kg the absence (control – CTRL) or presence (CELL) of 2 ml cellulase/kg dry matter intake (DMI) for 70 days, which included 10-day adaptation period. The feed was offered three times daily at 07·00, 13·00 19·00 h, but single dose cellulase only 07·00 h. Goats hand-milked daily; milk production...
Thirty-six goats: 15 Alpine (AG), 13 Saanen (SG) and 8 Anglo-Nubian (ANG) were used to evaluate dry matter intake (DMI), body weight (BW) changes milk production validate Wood's model in lactation curves. The kids pre-weaning weight, weaning (WW) daily gain (DWG) determined. Milk was measured for a period of 90 d. DWG quantified daily, while BW recorded weekly. Performance 48 (20 AG, SG ANG), aged d evaluated. utilised describe goat's curve the different studied goat breeds. differed between...
El objetivo del estudio fue evaluar financieramente la engorda rural de guajolote blanco doble pechuga. Para cumplir con este propósito, se analizaron datos cincuenta guajolotes (379.90 ± 141.69 gramos PVI, 15 días nacidos), bajo metodología Análisis Costo-Beneficio (ACB) en las cuatro etapas producción (iniciación, crecimiento, desarrollo y finalización). Los resultados indicaron que un horizonte cinco años es rentable, al presentar una TIR (93.80%) mayor costo oportunidad capital (TREMA =...
The aim of this study was to evaluate effects free ferulic acid (FA) supplementation on productive performance, some blood metabolite concentrations, and carcass characteristics ewe lambs finished in a feedlot. Dorper×Pelibuey (n=20; BW=28.5±0.5 kg; age=5 mo) were individually housed pens assigned under randomized complete block design the following dietary treatments (n=10): daily feeding without (control) or with 300 mg FA/animal. feedlot period lasted 34 d then all slaughtered. Free FA...
The objective of this study was to evaluate the effects addition two levels calcium propionate on lamb performance and some carcass characteristics. Twenty-one male Creole lambs with an initial weight 25.3 ± 3.3 kg were randomly assigned one following treatments: 0, 10, 20 g propionate/kg diet (dry matter basis). Intake, daily gain, feed conversion, weight, rib eye area not affected (P < 0.05) by addition. Ruminal fermentation altered (rumen pH, volatile fatty acids concentration,...
An experiment was conducted to evaluate the effects of two lyophilised aqueous extracts Lysiloma acapulcensis (LAE) and Phitecellobium dulce (PDE) tree leaves on in vitro assessment hatching eggs, larval development migration gastrointestinal nematodes sheep using a general linear model. Treatments contained from both species at concentrations 0, 125, 250 500 µg/mL. Both albendazole levamisole were used level 1% as positive control. The extract LAE, compared PDE, showed better inhibition...
