For Excellence, the student needs to demonstrate comprehensive understanding of livestock reproductive techniques in commercial production in New Zealand.

This involves justifying the use of a selected reproductive technique in terms of timing, quantity, genetic potential, and the economics of production.

The student justifies the use of the reproductive technique of Controlled Internal Drug Release (CIDR) and has linked it to the quantity (1), timing (2), genetic potential (3) and the economics of milk production (4).   

For a more secure Excellence, the student could provide more extensive justification, linked to genetic potential, quantity, timing and the economics of production, such as quantifying the increases in milk produced or the additional profit that is provided by using CIDRs.

For Merit, the student needs to demonstrate in-depth understanding of livestock reproductive techniques in commercial production in New Zealand.

This involves explaining how the steps taken when performing each reproductive technique influence the success of the reproductive technique.  Reference to livestock reproductive systems and the hormonal control relevant to the technique is required.  

The student explains how one reproductive technique, Controlled Internal Drug Release (CIDR), successfully controls the oestrous cycle (1) to improve reproduction. References are made to the relevant hormones (2) and parts of the reproductive system involved (3). 

To reach Excellence, the student could justify the use of CIDRs in terms of quantity, timing, genetic potential and economics of production.

For Merit, the student needs to demonstrate in-depth understanding of livestock reproductive techniques in commercial production in New Zealand.

This involves explaining how the steps taken when performing each reproductive technique influence the success of the reproductive technique. Reference to livestock reproductive systems and the hormonal control relevant to the technique is required.

The student briefly explains how one reproductive technique, embryo transfer, successfully improves reproduction (1).  References are made to the relevant hormones (2) and the parts of the reproductive system involved (3). 

For a more secure Merit, the student could provide more detail in the explanations, linking each of the steps taken to the success of the technique.

For Achieved, the student needs to demonstrate understanding livestock reproductive techniques in commercial production in New Zealand.

This involves describing the steps taken when performing each reproductive technique. Reference to the structure of livestock reproductive systems is required.

The student provides a sequential description of most steps involved in the artificial insemination technique (1) and reference to livestock reproductive systems was made (2).

To reach Merit, the student could include more detail linking the steps taken to the overall success of the technique and make references to hormonal control and livestock reproductive systems.

For Achieved, the student needs to demonstrate understanding livestock reproductive techniques in commercial production in New Zealand.

This involves describing the steps taken when performing each reproductive technique. Reference to the structure of livestock reproductive systems is required.

The student begins to describe a broad perspective of how inter-uterine artificial insemination (AI) is performed on ewes (1). The relevant reproductive parts have been identified (2).

For a more secure Achieved, the student could more clearly describe the steps taken, in the order they are taken, and by making reference to and expanding on what is happening using the image of an AI technician performing the technique.

For Achieved, the student needs to demonstrate understanding of livestock reproductive techniques in commercial production in New Zealand.

This involves describing the steps taken when performing each reproductive technique. Reference to the structure of livestock reproductive systems is required.

The student briefly describes basic knowledge of what flushing involves (1).  Reference is made to short term increased nutrition (2).

To reach Achieved, the student could provide more detailed and accurate descriptions of the steps involved in carrying out the flushing technique. For example, the student could provide details about the use of high quality feed sources such as leafy pasture and silage that are capable of promoting liveweight gain, and about the increased effectiveness of the technique when ewes are fed such feeds prior to and during mating.
