“…Small ruminants constitute an essential economic and ecological segment in agriculture and small farming systems (Devendra, 2001). The goat (Capra hircus) is amongst the first species of small ruminants to be domesticated for meat and milk (Dubeuf and Boyazoglu, 2009;Galal, 2005). Although goats are distributed over all types of ecological zones worldwide, they are more concentrated in the tropical desert areas.…”

The study was devised with the aim to evaluate the relationship between hemoglobin (Hb) concentration and Packed Cell Volume (PCV) in beetal goats being reared under pastoralism. It also aims to devise a hematological formula for estimation of Hb from PCV. Female (n=59) and male goats (n=41) were bled for PCV determination through microhematocrit method, and Hb estimation through Sahli’s hemoglobinometer (HbD) as well as through calculation being 1/3rd of PCV (HbC). The HbD and HbC were statistically non-significant (P≥0.05) for male and female beetal goats. Overall, significantly (P≤0.01) positive correlation coefficient was noticed between HbD and PCV, and between HbD and HbC (r=0.75; adjusted r-square=0.57). As the overall model predicted that 57% variability in HbD could be deduced from PCV, hence, in order to enhance the prediction probability, the regression equation i.e. Hb concentration= 0.24(PCV) +1.5 was utilized to deduce corrected hemoglobin (CHb). The comparison of this CHb with HbD gave a non-significant (P≤0.05) difference. Similarly, linear regression of CHb with PCV gave a 99% prediction. We accordingly recommend a simplified pen-side hematological formula for deducing Hb concentration from PCV viz. Hb concentration= 0.24(PCV) +1.5 for beetal goats instead of its calculation as one-third of PCV.

“…Likewise, it is necessary to develop abilities in farmers to improve management practices (Salinas and Rumayor, 1999) and reduce animal health problems (Echavarría et al, 2010). Similarly, it is imperative to add value to primary production and to focus products on specialized segments.…”

Objective: To determine the positioning of the most important livestock productionchains in Zacatecas, Mexico, within a matrix of socioeconomic importance andmarket competitiveness, and to identify research and technology transfer needs.Design/Methodology/Approach: Arranging livestock production chains into ahierarchy was carried out based on the methodology proposed by the InternationalService for National Agricultural Research (ISNAR), taking as analysis axis thedimensions of socioeconomic importance and competitiveness. The six mostoutstanding livestock production chains in the state were selected.Results: The results placed the beef cattle chains as sustainable, the goat andsheep chains were placed as vulnerable, pork and honey were located in theretraction quadrant due to their low socioeconomic importance and competitiveness,and dairy cattle was placed in the strained quadrant.Study Limitations/Implications: It is important to take into account other links.Findings/Conclusions: Strategies for livestock production chains involve makingthe production more efficient through sustainable practices, providing technical assistance to producers, conducting research to generate technology, investing ininfrastructure, and generating products with added value that meet the needs ofconsumers.

“…Cattle on rangelands (free grazing) are usually grazing indiscriminately on native vegetation. Some studies of Mexican pastoral systems have shown deleterious effects on the local vegetation usually attributable to poor management of cattle [37] and other ruminant animals such as goats and sheep [38]. Hence, improved management practices could reduce local damage and increase food production.…”

Does Mexico Have Enough Land to Fulfill Future Needs for the Consumption of Animal Products?

Land demand arising from the consumption of animal products is one of the greatest challenges for future sustainability. Developing countries are changing rapidly in both the consumption of animal products and the livestock production systems. Mexico is used as an example of a developing country. An approach is developed to identify the production variables that drive the Land Requirement for Animal Products (LRAP) for beef, milk, pork, chicken meat, and eggs. An average medium-scale farm of Mexico is described using farm-scale production data from the National Agricultural Survey of Mexico. The results show that the use of grassland outweighs the use of cropland for feed production, and the use of barn area is least. The production of beef protein requires more land than any other animal product because of its large demand for pasture land. The use of grassland represents 70% of the total demand for land for food by the Mexican population, and this is mainly for beef and milk consumption. Population growth and changes to a more affluent diet will result in a demand for more land for food; however, there will not be enough land if food is produced with present livestock production systems. It is necessary to implement strategies to reduce the use of land for food by focusing on both production and consumption.
