The aim of this study was to verify the effects of environmental impact caused by dioxin on milk production and metabolic profile in the buffalo cows. The authors analyzed some representative blood parameters related to their different metabolisms, the amount of zinc in blood samples, and milk production parameters, on 160 buffalo cows raised in four farms located in areas with a different environmental impact. Urea, glucose, creatinine, AST (aspartate aminotransferase), ALT (alanine aminotransferase) and zinc contents were determined on serum samples. Milk samples from each buffalo were collected. Daily milk yield and milk composition were significantly different among farms. No difference in milk protein content was found. Urea content, was higher. Glucose concentrations were significantly lower than in farms located in an area contaminated by dioxin. Creatinine values were normal. AST and ALT values were slightly higher than normal.  So far, there are not studies on the effect of dioxin on production and metabolic profile in buffalo cows. This study indicates that buffalo breeding herds exposed to dioxins would induce damage in the hepatic parenchyma cells as a result of animal welfare. Accordingly, the effects of environmental pollutants may expose the animals to several infections and diseases, which could affect not only the production traits, but also the qualitative features of their products devoted to human consumption.

Contribution/ Originality
Considering the increasing economic relevance of the Buffalo and considering the insufficiency information in the literature on the influence of micro pollutants on the buffalo, this work has focused the attention on the influence the environmental impact on buffalo health and on their production. It is important to remember that the animal is closely linked to the area, monitoring animal’s means monitoring the breeding environment.

Effect of a Plant Extract in Several Traits of Plymouth Rock Barred Hens and Pullets Challenged with Salmonella Typhimurium in a Rural Village in Central Mexico. Animal Review, 3(2): 43-51. DOI: 10.18488/journal.ar/2016.3.2/101.2.43.51
The effect of Chrysactinia mexicana Gray extract on poultry challenged with Salmonella typhimurium, was evaluated: 1) The aim of the survey was to understand the status quo of backyard poultry production in a rural area, 2). A field study with forty Plymouth Rock Barred Laying hens were used to test the effects of C. mexicana, and 3) 160 day old Plymouth Rock Barred pullets, were assigned to: T1 control; T2 control + S. typhimurium challenge; T3 control + S. typhimurium  + C. mexicana; and T4 control + S. typhimurium + antibiotic. Crop, gizzard, proventriculus and duodenum colony forming units (CFU) were measured, and leukocyte and erythrocyte counts. In addition, weight gain and feed intake was measured. The liver, bursa, thymus and spleen were weighed. Results show that 75% of farmers in the community have hens. The main diseases in their fowl: respiratory 45%; diarrhea 35% and parasites 20%. 90% of farmers have no access to veterinary services. Results from the field study show differences (P<0.05) between the treated group with C. mexicana and the control group with no treatment. Feed intake, total weight gain and final body weight was higher (P<0.05) for control group among the other treatments. Treatment challenged plus antibiotic showed lower CFU counts than treatment with S. typhimurium and C. mexicana. Thymus, bursa and spleen weights were similar (P>0.05) for the C. mexicana and antibiotic treatments. Leukocyte and erythrocyte counts were lower (P<0.05) in control group. C. mexicana extract could be a tool to diminish bacteria in hens.

Contribution/ Originality
This study is one of very few studies which have investigated the use of Larrea tridentata extract on poultry performance challenged with Salmonella  typhimurium

This research was carried out at two farms located in the Karacabey region of Turkey: an extensive goat farm (A) and a semi-intensive goat farm (B). A total of 32 Saanen goats (3 years old) at an early stage of their second lactation were selected from Farm A and Farm B. The total DM intake (TDM) values were 1.89 and 1.86 (kg d-1) for goats housed on the A and B farms, respectively. Compared with Farm A, Farm B produced more milk each day (P<0.05; 1.38 -. 1.76 kg day-1). The milk samples taken from Farm A had a higher (P<0.05) milk fat content than the samples from Farm B (milk fat=4.40 and 1.89 %, respectively). The serum creatinine values were significantly higher (P<0.05) in the blood of goats from farm A compared with farm B (1.11 and 0.56 mg dl-1, respectively). Comparison of glucose levels from both farms showed a significantly higher level of glucose in the blood samples from goats at Farm B (P<0.05; 24.23 and 61.43 mg dl-1). Serum parameters for cholesterol, GGT and urea were not affected by the feeding system (P > 0.05).

Contribution/ Originality
This study is one of very few studies which have investigated the milk composition, bacteriology and selected blood parameters of dairy goats under different feeding systems.
