Nutrition matters for every living thing and a complete diet with balanced nutrients is a canonic right for humans and animals. Agricultural products possess a substantial position to fulfill the requirements of both animals and humans. The soybean being a part of the Leguminosae family is a very renowned paltry source of protein in consecrated nature. Due to unique nutritional potentials, the usage of soybean in humans and livestock is very frequent. Soybean averts humans from different diseases and boosts up the milk, meat and wool production in animals. Besides many benefits, the soybean also begets some health upsbot and disasters. So this article particularizes the absolute composition, nutrition value, emoluments and drawbacks of soybean and permits the different researchers to explore more about soybean.

The objective of this study was to estimate the effect of inbreeding on birth weight (BW), weaning weight (WW90), and lamb survival rate (LSR) in Sakiz sheep. The effect of inbreeding on BW, WW90, and LSR traits was studied by analysis of variance technique and regression method. Inbreeding had a significant effect on BW and the regression coefficient of inbreeding on BW was -0.0245+/-0.0076 kg (P<0.01). The mean level of inbreeding (F) of all animals overall years was 2.25% for lambs. The inbred lambs rate was 17.7%. The coefficient of inbreeding ranged from 6.25% to 25.0% and average was 12.68% for birth weight in inbred lambs. Inbreeding weren't a significant effect on weaning weight at 90 days of age and lamb survival rate. It was concluded that inbreeding showed deleterious effects on birth weight and had a no effect on lamb's weaning weight and survival rate.

In this study, the effect of GnRH treatment applied on day 12 after timed artificial insemination (TAI) on pregnancy rate was investigated in Holstein heifers. A total of 56 heifers was randomly divided into control (n=28) and experimental (n=28) groups. All heifers were treated with PGF2 analogue on days 0 and 14, GnRH analogue on day 16 and TAI was performed 16 h after GnRH injection. The experimental group was treated with additionally GnRH injection on day 12 after TAI, while control group did not receive any injection. Pregnancy diagnosis was determined by real-time ultrasonography on days 30 and 45 after TAI in heifers. The pregnancy rates were found as 60.7% and 57.1% in experimental and control groups, respectively. Although the pregnancy rate in the experimental group was determined to be higher than the control group, the difference between two groups was not statistically significant (P> 0.05). In conclusion, it is suggested that the injection of GnRH applied on day 1...

ABSTRACT The objective of this study is to compare the reproductive performance of ewes, the lambs’ growth characteristics, and the variable costs in the sheep enterprises for the ex-situ and the in-situ conserved Kivircik sheep flocks. In total, 1841 ewes were included in the study. The ex-situ Kivircik sheep flock had 929 ewes and the in-situ Kivircik sheep flock had 912 ewes and their l864 lambs were born in the months January and February from 2007 to 2011. The lambing rates of the in-situ and the ex-situ flocks were 83.9% and 74.7% (P &lt; 0.01), respectively, the differences in the results were significant between the conservation types. The fecundity of the in-situ and the ex-situ flocks was 1.1 and 1.0 lambs (P &lt; 0.01), and the litter size was 1.3 and 1.3 lambs (P &gt; 0.05), respectively. The least squares means of the birth weight, the weaning weight at the 90th day of the lambs, and the post-weaning daily live weight gain of the in-situ and ex-situ conserved lambs were 4.2 and 3.7 kg (P &lt; 0.01), 25.4 and 24.9 kg (P &lt; 0.01), and 234 and 234.3 g/day (P &gt; 0.05), respectively. The average mean survival rate of the in-situ and the ex-situ conserved lambs were 96.2% and 90.0%, respectively, and differences were significant (P &lt; 0.01) between the conservation types. In the ex-situ sheep enterprises, proportional profit was 0.62, in other words, each 100 € expense corresponds to a loss of 38 €. However, for the in-situ sheep enterprise, this ratio was 1.17, meaning that each 100 € expense corresponds to a profit of 17€. The present study demonstrated that the in-situ conserved Kivircik sheep had higher growth performance, lamb survival rate and was more profitable than the ex-situ conserved Kivircik sheep.

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...
