REPRODUCTIVE PERFORMANCES OF SUMBA ONGOLE COWS INSEMINATED WITH FROZEN BELGIAN BLUE SEMEN

The purpose of this study was to observe the reproductive performances of Sumba Ongole (SO) cows inseminated with frozen Belgian Blue (BB) semen. This research was expected to be used as a reference in the cow’s maintenance, especially in the implementation of Artificial Insemination (AI), as well as for subsequent studies. Parameter of this study includes the signs of estrus symptoms, S/C ratio, CR, NRR, and pregnancy time. The results showed a large value of S/C for cow SO 2.60±1.81, great value for cattle CR SO was 40%, the value of NRR was 60%, and the pregnancy time SO was 273.80±4.08. It is concluded that reproductive performance of SO cows are good, using SO cows to cross with BB cow is possible to do.

Estimation of Most Probable Producing Ability Value for Calf Birth's Performance in Sumba Ongole Cows

An estimation of most probable producing ability (MPPA) value based on the calves performance is very important for the cow selection. The birth data record of 48 Sumba Ongole (SO) cows and record data from 52 callf birth's performance were used to estimate the value of MPPA. High of r value (r > 0.30) was obtained at the body length (BL). Birth weight (BW), withers high (WH) and chest girth (CG) had a moderate value (0.10 < r < 0.30) of repeatability. The MPPA value of the cumulative calf birth's performance of cows based on the highest birth records was 4.64 (cow number 3770) and the lowest was -4.64 (cow number 2283). Calf number B2076 (cow number 3586) had the highest ratio of WH (115.70); BL (124.26); CG (118.90), while the highest ratio of BW (168.35) was obtained in calf number B2095 (cow number 3731). It was concluded that the BW of birth had a moderate value of r (0.10) and could be used as a selection criteria accurately

The Potential Cost to New Zealand Dairy Farmers from the Introduction of Nitrate-Based Stocking Rate Restrictions

Introducing a stocking rate restriction is one possible course of action for regulators to improve water quality where it is affected by nitrate pollution. To determine the impact of a stocking rate restriction on a range of New Zealand dairy farms, a whole-farm model was optimised with and without a maximum stocking rate of 2.5 cows per hectare. Three farm systems, which differ by their level of feed-related capital, were examined for the changes to the optimal stocking rate and optimal level of animal milk production genetics when utility was maximised. The whole-farm model was optimised through the use of an evolutionary algorithm called differential evolution. The introduction of a stocking rate restriction would have a very large impact on the optimally organised high feed-related capital farm systems, reducing their certainty equivalent by almost half. However, there was no impact on the certainty equivalent of low feed-related capital systems.environmental regulation, dairy farms, whole-farm model, evolutionary algorithm, Environmental Economics and Policy, Livestock Production/Industries, Q12, Q52, C61,

Uniqueness and the Image of God: A Theological and Philosophical Justification of the Value of Diversity

In Christian education, cultural diversity is valued. But what is the theological basis for that value? While our commonality as human persons is rooted in the image of God, what about the diversity of human beings and the cultural diversity flowing from it? This essays argues that although the image of God is common to us all, there is an account of the image of God that provides for uniqueness as well and that individual uniqueness is at the core of human being as we participate in our cultural forms of life
