The aim of the study was to determine the prevalence of helminths in cattle in Kirinyaga County in association with the agro-ecological zones, breed types and animal management styles. Epidemiological data was collected using a questionnaire survey administered to 244 respondents. Fecal samples from cattle were collected within a period of four months to determine helminths and protozoa egg counts. The study revealed that there was a significant association between the type of management style used and helminth infestation. The grazing style of management significantly related to helminths infection (P< 0.05). When considering the various cattle breeds, Arshyires and Friesians were significantly associated with helminth infection at 24 and 50 times higher than the crosses and zebu breeds. Helminth presence was significantly associated with agro ecological zone from which cattle came from. Coccidia was significantly associated with age and breed of cattle (P<0.005). The calves were 4 times more likely to be affected by coccidia than adult cattle while the yearlings were about 3.8 times more likely to be affected by coccidia. The Friesian was 4.9 times more susceptible to coccidia infection than other breeds. In conclusion, during the control and treatment of cattle helminthiasis, agro-ecology, species, age and sex of the animals should be considered as potential risk factors for the occurrence of the disease in the study areas.

There is no doubt thateconomic efficiency achieve when all the inputs factors use in an efficient way. The aim of this paper is determined the demand for Labor and the impact of the relationship between the Labor and Capital in the Iraqi agricultural sector during the period 1990-2014 rely on the dual approach by using the profit and cost models. To estimate the profit function it used the Cobb-Douglas model, and the results showed that the Labor demand elasticity for the worker’s wage is -0.87, and that means when the wages are rise about 10% the demand of Labor will reduce about 1.78%.The cross-sectional elasticity between labor and capital is about 4.6, and that means for any increase in the capital such as 1% led to increasing the labor by about 4.6%. That confirms the hypothesis of this study where there is a substitutional relationship between the labor and capital for labor than capital, which means whenever to increase the capital or any technology improvement led to increasing the production and raises the investment. The labor demand function showed that the elasticity of the worker’s wage for the value of the wages in the agricultural profit is about 0.462. That is mean when the employee’s salary increase 1% the wages increase 0.462% from the profit, however; this rate is very low because of the agricultural sector depends on the family work regardless of the level of the wages. The cost function is determined too and used the Cobb-Doglegs model by using the Eviews.6 program. The results showed when the wages increase 1% the agricultural costs will increase too for about 16.2%, and that is mean the Iraqi agricultural sector still have real problems of disguised unemployment.

Rice cultivation in peat swamp agricultural lands in South Kalimantan has significant relationship with the issues of global warming. The aims of the study was to identify the methane gases releases from paddy field which are cultivated by local rice in Tamban sub district, Barito Kuala, Kuala Regency in South Kalimantan. Four local rice cultivars namely Siam Unus Putih, Pandak Putih, Siam 11 and Siam Rukut were cultivated in peat swamp paddy field. Methane release from each paddy cultivar was measured using close chamber technique. Research of the study shows that the emissions of methane from peat swamp paddy field with local rice cultivation during vegetative growth was increase and decrease during generative growth periods. The total methane emission in one season from Siam Unus local rice was estimated about 0.032 Kg/Ha while Siam Pandak rice was release methane about 0.019 Kg/Ha. This data shows that the contribution of paddy field with local rice has lowest methane emission compared from the peat swamp agricultural land with superior rice about 1.3 Ton/Ha.

The dairy cows in Dharmapuri district of Tamil Nadu are reared with limited amount of dry fodder, green grass and wheat bran as concentrate sources. This affects the productive and reproductive performance of dairy cows. Hence an attempt was made to assess the deficit per cent of nutrient intake in comparison with NRC (2001) feeding standard, in eight regularly cycling repeater, Jersey cross (Jx) and Holstein Friesian cross (HFx) cows. The results revealed there was deficit /kg of dry matter intake (DMI) in Total digestible nutrient (TDN), crude protein (CP) and calcium (Ca) was The deficit /kg of dry matter intake (DMI) in Total digestible nutrient (TDN), crude protein (CP) and calcium (Ca) was 1.65 kg/day, 1134, 413 and 29 g/day, respectively and intake of phosphorus was excess by 0.64 g/day in Jx and in (HFx) cows the DMI,TDN, CP and Ca deficit were 1.26 kg/day, 865, 394 and 25 g/day, respectively and intake of phosphorus was excess by 13 g/day. Considering the low levels of calcium and excess phosphorous intake of the animals when compared to NRC (2001), supplementation of commercially available mineral mixture at the rate of 50 g per cow per day was done from day of insemination till the days of confirmation of pregnancy (90 days). Even though there was deficiency of other nutrients in this experiment, the trial was planned with mineral mixture alone to ascertain whether feeding mineral mixture alone will be sufficient to mitigate the repeat breeding problems. The result of the study concluded that repeater problem can be nullified to 75 % in Jx cows and 87% in HFx cows on supplementation of mineral mixture at the rate of 50 gm/day from the day of insemination to 90 days.

Experimental trials were conducted to evaluate the fecundity and egg size of Clariasgariepinus brooders (700 990g) in Pandam Lake, Plateau State, Nigeria. Thirty female fish were caught using gill nets and long-line gears. In addition, fishermen's catch was also sampled to increase sample size and fish size. Fish were dissected and their ova sac removed, weighed and preserved in 5% formalin to prevent quick egg-freezing action before counting. An ocular micrometer (Mg=0.019 mm) was used to obtain the egg size. Regression analysis was applied to assess the total length and body weight, total length and fecundity, body weight and fecundity dependence of the brooders. A unit increase in the length of the fish lead to 0.52g increase in the body weight. Between total length and fecundity, there is a significant connection with p-value less than the level of significance at (p > 0.05) with a very high value of coefficient of correlation at r=0.988. Similar results were obtained for body weight and fecundity but with the coefficient of correlation at r=0.917. Absolute fecundity and relative fecundity were found to be related to the body weight of the fish. Each of these relationships is statistically significant (p<0.05). The egg size ranged between 1.13mm to 1.16mm. The result indicates that the relative fecundity increased with increasing body weight and total length.

Nine cucumber genotypes, represented pure local and imported classes,were cultivated to evaluate genetic diversity and determine genetic affinity among them by using 13 starters kind Inter Simple Sequence Repeats (ISSR), 10 of them showed an activity to give apolymorphism among the studied genotypes which give 94 alleles, the ratio of this polymorphism was 68%. The starter UBC862 gave higher bands of 15, while the starter A35 gave lower bands of 6. The study showed that genetic similarity of the genetic affinity ranged between 0.506 – 0769 in which the higher genetic affinity (0.769) was for V5 and V2 varieties followed by (0.743) for V6 and V3 varieties, while the lower genetic affinity (0.506) was for V8 and V9 varieties.
