In cattle breeding, growth curves are used for determining the most appropriate slaughter age, obtaining information about the general health status of animals, estimating the age of sexual maturity and the age of use in breeding, and selection studies. The aim of this study is to estimate the growth curves of Holstein calves using the Bayesian Approach of Brody, Logistik, and Von Bertalanffy models. The live weight data was collected from 34 Holstein calves raised at the cattle research farm of Niğde Ömer Halisdemir University, Ayhan Şahenk Agricultural Research and Application Center in 2019. Furthermore, for estimating the frequency modeling of the Holstein breed the predicted parameter values and standard deviation of parameters were used as the prior information. The Bayesian approach was used for making the statistical analysis. Monte Carlo Method Markov Chains (MCMC) algorithms were used to estimate the posterior distributions and it was 900,000 in total while excluding the 8...

Globally, 16.9% of milk used by humans is taken from different species other than a cow. These species are sheep, horse, yak, ass, goat, camel and buffalo. The global camel (Camelus dromedarius) population is about 34 million head with sharing of almost 0.4% of world’s non-cattle milk. Within the last 20 years, the curiosity of camel farming is amassed remarkably in different countries of the world including the Netherland, Italy and USA for camel milk production. The camel is considered as a goal animal of the 21st century because it produces high quality milk under extreme temperature, deficiency of pasture and dearth of water. The average milk production of camel fluctuates from 4 to 30 lt with lactation length ranges from 9 to18 months having peak yield in second to the third month of lactation. Camel’s milk is used globally because of its salty taste, high vitamin C concentration and its medicinal properties. Nevertheless, it gives many valuable benefits such as treatment of au...

Migratory beekeeping, has become an important issue in increasing productivity of colony, but today it has become an important challenge to find staff to load and unload bees. The necessity of carrying bee transportation usually between illusions and at night time, as well as the problem of not finding the workers to work due to bee insertion problems have also brought about. In addition to the transportation of beekeeping between the cities in the migratory beekeeping, it is another factor that increases the operating expenses, even if the colonies are both loaded and unloaded and require separate labor costs. As a consequence, it is difficult to find the workers in the transportation of bees and because of the high cost of labor, the traveling bee is getting away from being economical. The constant increase in fuel prices and the increase in transportation costs are another negative factor that adversely affects migratory beekeeping negatively. Due to these problems of loading and...

This study was conducted to investigate the effects of year, parity and birth type (BT) on lactation milk yield (LMY), adjusted lactation milk yield based on 150 days lactation length (LMY150), lactation length (LL), average daily milk yield (ADMY) and milk components (MC) of Bandirma sheep. The study was carried out with 54 ewes in 2011 and 70 ewes in 2012 under semi-intensive conditions. LMY, LMY150, LL and ADMY of Bandirma sheep were determined as 70.31 kg, 73.29 kg, 142.02 days and 488.19 g, respectively. The effect of the year on LL was significant (P<0.01), but the effects of parity and BT were not significant. The effects of the year and parity were significant (P<0.01 and P<0.05, respectively) on LMY, LMY150 and ADMY, but the effect of BT was not significant. Fat, protein, lactose, total dry matter (DM) and non-fat dry matter (NFDM) were determined as 5.26%, 6.11%, 3.29%, 15.49% and 10.23%, respectively. Highly significant positive correlations were determined between fat content and DM (r= 0.998; P<0.01) and between fat content and NFDM (r= 0.949; P<0.01), whereas fat content was negatively correlated with ADMY (r= -0.992; P<0.01) and lactose content (r= -0.957; P<0.01). Significant negative correlations (P<0.01) were found between lactose content and other milk components except for protein content and ADMY. The results indicated that despite being a mutton type crossbred, lactation characteristics and MC of Bandirma sheep are also considerable.
