The aim of the study was to describe the scenario of the present condition of production and management system of dairy buffalo at Haor areas of Sylhet in Bangladesh. Data were collected between February 2019 and January 2020. Sixty dairy farmers and thirty indigenous dairy buffaloes were selected for the study purpose. All respondent farmers were male and 65% were in between 40 to 50 years of age. Parity number had a significant relation in response of body weight. Quality analysis of milk showed that buffaloes which were reared at Haor areas have more fat content on an average 7.88% than buffaloes which were reared conventional dairy farm containing 7.34%. Price of buffalo’s milk and meat were varied with the seasonal changes, lower in winter season. All farmers fed the buffaloes only with green grass in winter. Four major diseases of buffaloes were found in Haor areas where the percentage of foot and mouth diseases was 15.59% followed by black quarter (11.01%), anthrax (7.34%) and hemorrhagic septicemia (6.42%). The buffaloes were not dewormed so parasitic infestations dramatically increased and easily transferred from one to another. The farmers had not enough knowledge about regular vaccination. But in contrast with profitability, total benefit cost ratio from buffalo rearing was 1:1.56 annually.

2021
Rabia Göçmen | Gülşah Kanbur
This study was conducted to investigate the effects of hemp seed oil replaced soybean oil as an energy supply on growth performance parameters, carcass yield, liver weight, breast meat pH, and meat color values in quails. A total of 100 one-day old quail chicks were reared in two treatment groups for 5 weeks. The experimental diets were formulated as to contain 4.4% crude soybean(control) and hemp seed oils. According to the results of the present study, crude hemp seed oil replaced soybean oil in the diet was effective on finishing body weight, feed intake, feed conversion ratio, weight gain and carcass yield. All of these parameters were lower than the soybean oil (control) group. Liver weight, and breast meat color values (L*, a*, and b*) have shown similarities between experimental groups. The breast meat pH value decreased significantly in the hemp seed oil treatment group compared to soybean oil group. Using hemp seed oil instead of soybean oil used in quail diets negatively affects performance parameters (except for feed conversion ratio).

Salmonella species are important foodborne pathogens that have been implicated in a number of foodborne outbreaks. A total of 240 beef and its related samples obtained from the Techiman Municipality of Ghana were screened using the conventional method in the Food and Drug Administration-Bacteriological Analytical Manual (FDA-BAM)-USA. The overall prevalence of Salmonella species was 57.08%. The prevalence of Salmonella species ranged from 33.30% to 75.00% in the meat and its related samples (table, knife and apron), and 6.30% to 93.80% at the various meat sale points (locations where meat is sold). Prevalence of Salmonella species was significantly higher in meat (75.00%), table (60.00%) and knife (60.00%), than apron (33.33%). The most contaminated meat sale point was Kenten and Main markets (93.75%) and the least contaminated sale point was Sansema junction (6.25%). All the Salmonella species were susceptible to ciprofloxacin but resistant to vancomycin. Intermediate resistances occur for all the antibiotics except ciprofloxacin and vancomycin. The Salmonella species also exhibited 23 antibiotic resistant patterns with the pattern EVa (erythromycin and vancomycin) being the commonest (exhibited by nine different isolates). Multiple antibiotic index (MAR index) ranged from 0.11 to 0.67. This study revealed that beef and its related samples in Techiman markets are contaminated with Salmonella.

2020
Muyiwa Adegbenro
In developing nations Nigeria inclusive, most of the cereals grown are for human consumption. Conventional feedstuffs use in livestock production especially in poultry enterprise has intensified the competition for available grains. Consequently, the cost of poultry production is jacked up. Since poultry provides most of the animal protein consumed either in the form of meat or egg, exploring tropical vegetables as a route of escape to reducing the cost of feeding will be a great gain in the poultry enterprise. Tropical vegetables especially the African leafy vegetables (ALVs) are economical and highly nutritive possessing good levels of vitamins, minerals, protein and essential amino acids. The mineral constituent of some tropical vegetables as well as their nutritive impact on the performance, meat quality, egg quality in broiler and laying birds as presented in this review paper. Although, the availability of ALVs all year round, its moisture content level and presence of anti-nutrients may tend to limit its usage in poultry feed, adopting irrigation techniques and improved seedlings as well as exploring the processes of enhancing the nutritional value of ALVs to combat anti-nutrients to tolerable levels by the birds make it possible to be considered as good alternative in poultry diets.
