Litter (n = 8,424) and female performance records were collected in two breed-to-wean production units in order to evaluate genetic line differences for sow longevity and maternal performance over four parities. Lines evaluated were American Diamond Genetics, Danbred North America, Dekalb-Monsanto DK44, Dekalb-Monsanto GPK347, Newsham Hybrids, and National Swine Registry. Females within a line ...

The California black rail (Laterallus jamaicensis coturniculus) and Virginia rail (Rallus limicola) are cryptic species of marsh birds that often coexist in the same wetland sites. The black rail is currently listed as threatened in California. Little is known about the diet of either bird species and their interactions due to their secretive nature. It has been suggested that black and Virgini...

This study was conducted to evaluate changes in composition of whey proteins of Czech White Short-haired goat and East Friesian ewe milk and their comparison throughout lactation. Some differences in composition between ewe and goat milk were found. The results showed that the mean total protein (%), whey protein (g/100 g), and β-lactoglobulin (β-Lg, g/100 g) contents of goat milk were 2.75, 0....

Inheritance of economic traits was studied in Nili-Ravi dairy buffaloes through analysis of data comprising 5037 records of daughters of 79 sires. Data were collected from three large-sized state dairy farms. Heritability, genetic and phenotypic correlations of some indicator traits on important production and reproduction traits were worked out. Based upon analysis of records for first lactati...

KADLECOVA, V., D. NEMECKOVA, K. JECMINKOVA and L. STADNIK, 2014. The effects of polymorphism in the DgAt1 gene on energy balance and milk production traits in primiparous Holstein cows during the first six months of lactation. Bulg. J. Agric. Sci., 20: 203-209 The aim of this study was to analyze the effects and significance of DGAT1 K232A polymorphism on milk production traits – milk yield, co...

Buffalo husbandry plays a crucial role livelihoods numerous farmers across various upazilas Mymensingh. A total 100 indigenous were selected for study, representing four upazilas: Trishal, Haluaghat, Muktagachha, Sadar upazilla district. findings this reveale...

A total number of 88 fishes Thai pangas were conducted for induced spawning experiments. Among them, 30 mature Pangasius sutchi were conducted for the length-weight relationship, 25 matured females for the fecundity and 33 fishes (12 males and 21 females) for induced spawning experiments. The total-standard length relationship curve shows a straight line with a strong correlation (r = 0.986 and...

Our objective was to study the effects of dietary energy source (fat or starch) on periestrus hormone profiles and embryonal survival in primiparous sows. During lactation, 48 primiparous sows were fed either a starch-rich or a fat-rich diet, at either a high (44 MJ NE/d) or a low (33 MJ NE/d) feeding level. After weaning, all sows received the same amount of feed (31 MJ NE/d from weaning to es...
