Farm trials were conducted to determine if the calving rate was different for control cows inseminated with frozen semen at estrus in comparison to cows treated with progesterone for 12 days and bred at the ensuing estrus. Intravaginal silastic coils impregnated with progesterone were used and an injection of 5 mg estradiol benzoate and 50 mg progesterone in corn oil was given at the time of in...

Profiles of blood metabolites have widely been used as part of a multidisciplinary approach to identify metabolic disorders in dairy herds. Our goal was to identify constraints on productivity of cross bred HF herds and set up baseline hematologic and serum biochemical values. The values were determined in pre-parturient cross bred Holstein Friesen (HF) cattle of Nepal. The study was carried ou...

abstract in agriculture, there is a lag between planting decision and supplying the produced commodity to the market. this makes the marketed commodities as predetermined variables and prices as market clearing factor. under such a condition, the inverse demand function in which price is a function of quantity is an appropriate tool for forecasting price responses to the injected quantities to ...

The data set used in this study contained 8793 records of lamb's longevity (days) from 320 sires and 2349 dams collected during 1989 to 2014, from the Lori-Bakhtiari flock at Shooli station in Shahrekord, Iran. Genetic parameters (partitioned into autosomal, sex-linked and maternal) and breeding values of cumulative lamb's longevity from birth up to yearling age (at 1, 2, 3, 6, 9 and 12 months)...

in this study, in addition to estimating meat demand, live animal supply and marketing services supply for beef and lamb, economic behavior of marketing margin with respect to determinants of meat demand, live animal supply and marketing services supply have been evaluated for years 1998-2004. results indicate that, as examples, beef and lamb marketing margin elasticity with respect to feed pri...

the present study was conducted to evaluate the effect of parenteral supplementation of cobalt, copper and iron in late pregnancy on ewe hematology parameters and lamb vigour. twenty ewes were allocated to one of two groups (n=10). in the test group, on day 120 ofpregnancy, cobalt, copper and iron were injected at a dose of 0.1 ml/kg bw (fercobsang, france, cobalt gluconate 5 mg/100 ml, copper ...

Seasonality of breeding was evaluated in 165 purebred St. Croix ewes over a period of 3 yr at a latitude of 35 degrees 6' N. Ewes were divided into six groups for breeding starting in August of 1989 and a group was exposed to rams every 2 mo throughout the experiment. Lambing percentage was lowest for spring breeding (P < .01), which resulted in lower numbers born and weaned per ewe exposed (P ...

2015 © American Water Works Association JOURNAL AWWA OCTOBER 2015 | 107:10 Tularemia is an acute febrile zoonotic disease caused by the bacterium Francisella tularensis. Shortly after the initial isolation of the organism in Tulare County, Calif. (McCoy & Chapin 1912), the first case of a human infection was reported from Cincinnati, Ohio (Wherry & Lamb 1914). The first documented waterborne ou...
