Background: Fetal programming was a term used first in humans, then it spread thanks to different research done on domestic animals to determine the effects on the progenies of nutrition during the early, intermediate, and final stages of gestation, and their short-term repercussions on the productive, reproductive, and immunological parameters, such as birth and weaning weights. Aim: To present this concept and analyze birth and weaning weights as reference information for buffalo progenies. Development: This paper deals with the concept of fetal programming and its impact on raising; the weight-related data collected upon buffalo calving were shown. Conclusions: The scientific evidence demonstrated the relevance of the nutritional state of the cows during fertilization and gestation, as well as the low weaning weights of the progenies. It means that a change of mindset is necessary in livestock raising, by considering this scenario as a starting point to produce offspring with the proper weight required for further production and reproduction.

The aim of this paper was to evaluate the reproductive behavior of female Zebú and 5/8 Zebu x 3/8 Simmental on a genetic farm in the central region of Cuba. The research was made between 2010 and 2014. The individual records of 255 cows; 200 Zebus (106 White and 94 Bermeja) and 55 crossbreds (5/8 Zebu x 3/8 Simmental) were included. The calving-first insemination interval (CFI) and calving-gestation interval (CGI), inter-calving period (ICP), and service per gestation (S/G) were calculated. Besides, the effects of genotype, parity, quarter and year of calving were evaluated using the above indicators. The descriptive stratigraphy was calculated, and a general linear model was used to determine the effects of each variation source. The three genotypes showed low reproductive efficiency, though slightly more favorable for 5/8 Zebu x 3/8 Simmental. The calving year, genotype, and parity influenced (P < 0.05) the CFI, CGI, and ICP. The calving quarter only influenced (P < 0.05) the CGI. The gestation service was not influenced by any factor. It was concluded that the three genotypes studied underwent high deterioration of reproductive indicators, influenced by the genotype, quarter, calving year, and parity. [ABSTRACT FROM AUTHOR]

The purpose of this paper was to make a contribution to environmental arrangement of the livestock potential in the municipality of Jimaguayú, Camagüey, Cuba. The indicators, restrictions, categories and conflicts of livestock potential in the region were identified and located on a map. Additionally, the policies, guidelines, regulations, and standards for proper environmental management in each livestock raising area were determined. The study concluded that the potential of livestock raising depends on the environmental use recommended as principal in eight of the seventeen secondary environmental areas that make up the region; one of them was considered for secondary use. In terms of categories, the municipality comprises 126.9 km2 with inexistent livestock potential, including several settlements and water reservoirs; 115.7 km2 showed a poor potential; 316.3 km2 had a mid-potential; and 225.4 km2 was high. The previous contributed to proper environmental arrangement of livestock potential in the municipality of Jimaguayú, Camagüey. In accordance with it, restrictions, indicators, categories and conflicts observed in the sector were determined to make recommendations for development in the secondary environmental areas with some potential. This study was also useful to set up policies, as well as general and specific guidelines. [ABSTRACT FROM AUTHOR]

The indicators restrictions, categories, and conflicts of the livestock potential in the region were identified and located on a map. Additionally, the policies, guidelines, regulations and standards for proper environmental management in each livestock area were determined. The study concluded that the potential of livestock activity consists in environmentally recommended use in the main eight of the seventeen secondary environmental areas that make up the region. One of them was considered for secondary use. In terms of categories, the municipality comprises 126.9 km2 with inexistent livestock potential, including several settlements and water reservoirs; 115.7 km2 were identified as poor potential; 316.3 km2 had a mid-potential; and 225.4 km2 was high. The previous contributed to the environmental arrangement of the livestock potential in the municipality of Jimaguayú, Camagüey. Accordingly, the restrictions, indicators, categories, and conflicts observed in the sector were determined, to be used as recommendations for development in the secondary environmental areas with some potential, as well as to set up policies, and general and specific guidelines.

The present paper aim is to determine the causes provoking an antihelmintic resistance within livestock cooperative collective ventures. To this end, an exhaustive observation of antihelmintic drugs application and manipulation was carried out at different livestock centers from Camagüey province, Cuba. Technicians' role in a wrong drug dosage due to a mistaken animal liveweight estimate, drug contamination by non-sterile needles and other devices, and drug container refilling was assessed, and results were expressed in percents. A hundred veterinary doctors and technicians applying this antihelmintic treatment were interviewed. Data so compiled were processed by the SPSS program (10.0 version) to analyze in a crossed contingency table including doctor and technician categories their knowledge concerning dosage and parasite taxonomic group response to the mostly used antihelmintic products in Cuba, i.e., levamisol, ivermectina, albendazol, and niclosamida. A square chi test was finally applied and results showed an inadequate use of antihelmintic drugs. [ABSTRACT FROM AUTHOR]
