El metano (CH 4 ) es un gas subproducto de la fermentación los carbohidratos en el rumen.La agricultura contribuye con 47% las emisiones antropogénicas CH , siendo rumiantes responsables del 39% entérico.Este efecto invernadero (GEI) tiene potencial calentamiento global 25 veces más que CO 2 y representa una pérdida hasta 12% energía total consumida por rumiantes.Este trabajo describe mecanismos acción taninos condensados contenidos follajes frutos su microbios rumen, así como mitigación...
The aim of the experiment was to assess effect increasing amounts Leucaena leucocephala forage on dry matter intake (DMI), organic (OMI), enteric methane production, rumen fermentation pattern and protozoa population in cattle fed Pennisetum purpureum housed respiration chambers.Five crossbred heifers (Bos taurus×Bos indicus) (BW: 295±6 kg) were chopped P. grass levels L. (0%, 20%, 40%, 60%, 80% [DM]) a 5×5 Latin square design.The voluntary production measured for 23 h per day chambers;...
The use of Duddingtonia flagrans as a tool for the biological control gastrointestinal nematodes (GIN) is promising alternative to anthelmintics. chlamydospores D. are orally dosed and their thick cell wall gives them capacity resist digestion pass through tract (GIT). Chlamydospores reaching faeces able germinate trap nematode larvae. efficacy this method based on reducing numbers infective larvae leaving faeces. Techniques have recently been developed quantifying in As number non-digested...
Los ovinos de pelo juegan un papel importante en la producción animal las regiones tropicales; sin embargo, sus requerimientos nutricionales no se han determinado misma medida que los razas lana. Debido a condiciones ambientales tropicales (clima, calidad y disponibilidad alimentos), es razonable hipótesis energía metabolizable (EM) eficiencia utilización EM pueden ser diferentes entre La información disponible muestra una gran discrepancia cuanto necesidades energía. Con base datos...
ABSTRACTRuminant animals contribute significantly to methane emissions in tropical regions. Nonetheless, there are few facilities available those regions of the world for vivo measurement production cattle. The aim present work was describe design, construction and operation respiration chambers cattle Mexico. Locally materials were used construction. Walls, roof doors constructed thermic panels with two windows acrylic at front so animal can be observed all times. Chambers have an air...
The aim of the study was to evaluate productive and reproductive performance dual-purpose (DP) cows with a restricted concentrate allowance access forage association Leucaena (Leucaena leucocephala) Stargrass (Cynodon nlemfuensis). Twenty-four multiparous Holstein × Zebu were used during first 98 days postpartum. Treatments control (CT): nightly grazing + commercial (3.97 kg dry matter [DM]/d), (LT): (1.97 DM/d) 4 h on an Leucaena/Stargrass. actual time spent browsing represented 38% total...
Summary The aim of the experiment was to assess effect condensed tannins ( CT ) on feed intake, dry matter digestibility, nitrogen balance, supply microbial protein small intestine and energy utilization in cattle fed a basal ration Pennisetum purpureum grass. Five heifers Bos taurus × indicus with an average live weight 295 ± 19 kg were allotted five treatments consisting increasing levels (0, 1, 2, 3 4% /kg DM 5 Latin square design. Dry intake DMI similar (p > 0.05) between containing...
In the Mediterranean region, artichoke and broccoli are major crops with a high amount of by-products that can be used as alternative feedstuffs for ruminants, lowering feed costs enhancing milk sustainability while reducing environmental impact dairy production. However, nutritional quality needs to assured under these production conditions an optimal inclusion ratio silages should determined. This work aimed evaluate effect three levels (25%, 40%, 60%) (artichoke plant, AP, by-product, BB)...
<p>The aim of the study was to evaluate effect metabolizable energy intake (MEI) on changes in body weight (BW) and condition score (BCS) non pregnant, lactating Pelibuey ewes. The experiment had two phases: first, 24 three-yr-old ewes were kept pens (six per pen) fed for 60 days homogenize BW BCS. Thereafter with 37.2 ± 4.1 kg, BCS 2.5±0.12 (mean±SD), randomly divided groups six animals, one group slaughtered baseline measurements; remaining assigned a completely randomized...
