Meat yield and growth was evaluated in crossbred F1 chickens (Gallus gallus domesticus) (Full Plumage Naked Neck × Rhode Island Red) backyard production systems under dry tropic conditions. Seventeen naked neck (MCD) seventeen full plumage males (MPN) were used at the locality of San Nicolás Arroyo Hondo, Municipality Huetamo, Michoacan, Mexico, fed with a traditional scheme (commercial concentrate plus corn). The variables analyzed body weight (PC); food consumption (CA); feed conversion...
The buffalo herds in Venezuela are characterized by a high phenotypic polymorphism, showing diversity among individuals. leading cause is the great mixture of breeds involved crossbreeding programs, such as Murrah, Mediterranean, Nili Ravi, Jafarabadi, and Carabao. Morphometric measurements assist racial characterization comparing genetic groups (within between) establishing relationship between conformation functional traits, eliminating undesirable characters, helping selection process for...
A retrospective study (2000-2022) was conducted in a commercial buffalo farm Mérida State, Venezuela, to assess the effect of month and lunar cycle at calving on some reproductive variables. According percentage moonlight, (29.52 days) divided into 30 periods (0.98 days each). The intervals calving-estrus calving-conception number services/conception were analyzed by general linear model. conception rate first service frequency Chi-square test (n=3510). parturition did not affect interval...
A retrospective study (2000-2022) was conducted on a commercial buffalo farm in Merida State, Venezuela, to evaluate the effect of reproductive management and parity performance. Reproductive split into two periods: 1) 2000-2013 (n=1382) 2) 2014-2022 (n=2128). In former, estrus synchronization protocols were applied mainly between November February, while latter, hormonal during whole year. The number calving divided 1 (1P) ≥2 (2P). general linear model analyzed intervals calving-estrus...
