The aim of this study was to compare the fatty acid (FA) profile of meat from New Zealand White rabbits raised from 30 to 90 days of age under intensive (IPS) and extensive (EPS) production systems. In group IPS, the rabbits were housed in wire mesh cages with a slatted floor (16.7 animals/m2) and were fed a commercial pelleted diet. In group EPS, the rabbits were housed in free-standing cages on straw litter (2.5 animals/m2) and were fed a conventional farm-made diet (green fodder, barley grain, stale bread, hay). The FA profile of intramuscular fat (IMF) was analyzed in samples of Longissimus thoracis et lumborum (LTL) muscle. The analyzed production systems had no significant effect on the content of most FAs in IMF. However, the differences between group means contributed to more desirable values of the quality indicators of IMF (in particular in the LTL muscle) in group IPS. The study demonstrated that the claim that meat produced under less intensive farming systems is of superior quality could be an oversimplified generalization that should be validated in research.

The Impact

Pregnant rabbits are a common nonrodent model for reproductive safety evaluation in preclinical drug development. During reproductive toxicology studies, rabbits are prone to decreased food consumption and anorexia. When persistent or severe, this condition can lead to hepatic lipidosis and pregnancy toxemia, which may confound the interpretation of study results. Non-Esterified Fatty Acids (NEFAs) have been used in veterinary production medicine to evaluate the impact of diet on the energy balance of pregnant animals. In the current study, sustained-release buprenorphine was used to suppress the appetite of pregnant New Zealand white rabbits, mimicking the clinical presentation of animals in reproductive toxicology studies. Sequential NEFA evaluations during gestation, along with other clinical endpoints, such as the necessity and duration of veterinary intervention, were used to evaluate the effects of feeding hay and a pelleted diet as compared with a pelleted diet alone. Elevated NEFA levels were directly correlated to litter size, the number of viable fetuses and the number of days on veterinary consult due to severely decreased consumption of pelleted diet. Animals with hay as part of their diet did not require additional diet supplementation as determined by qualitative evaluation of hay intake and adequate fecal output. These data suggest that including hay as a portion of the standard diet benefits pregnant rabbits in laboratory or production settings.

The Effect of Humic-Fatty Acid Preparation on Production Parameters and Meat Quality of Growing RabbitsThe aim of the study was to determine the effect of a humic-fatty acid preparation on production parameters and meat quality of rabbits. Three groups of New Zealand White rabbits were used (one control and two experimental) with 8 animals per group. The animals of group C (control) were fed standard pelleted diet, group H5 received a control diet supplemented with 5%, and group H10 a control diet with 10% humic-fatty acid preparation. The experiment was terminated after 6 weeks feeding, when rabbits were slaughtered. The experimental groups showed higher gains and a higher feed conversion ratio than the control group. The dietary inclusion of the experimental additive had a beneficial effect on the meat quality traits, such as Fe concentration, hardness and colour, but it also increased the susceptibility of fat to oxidative changes.

Intensive Farming

Modern greenhouses are intensive farming systems designed to achieve high efficiency and productivity. Plants are produced year-round in greenhouses by maintaining the environment at or near optimum levels regardless of extreme weather conditions. Many scientific discoveries and technological advancements that happened in the past two centuries paved the way for current state-of-the-art greenhouses. These include, but are not limited to, advancements in climate-specific structural designs and glazing materials, and temperature control, artificial lighting, and hydroponic production systems. Greenhouse structures can be broadly grouped into four distinct designs, including tall Venlo greenhouses of the Netherlands, passive solar greenhouses of China, low-cost Parral greenhouses of the Mediterranean region, and gutter-connected polyethylene houses of India and African countries. These designs were developed to suit local climatic conditions and maximize the return on investment. Although glass and rigid plastic options are available for glazing, the development of low-cost and lightweight plastic glazing materials (e.g., polyethylene) enabled widespread growth of the greenhouse industry in the developing world. For temperate regions, supplemental lighting technology is crucial for year-round production. This heavily relies on advancements in electro-lighting during the 19th and 20th centuries. The development of hydroponic production systems for the controlled delivery of nutrients further enhanced crop productivity. This article addresses important historical events, scientific discoveries, and technological improvements related to advancements in these areas.

Ostrich are currently being promoted as an alternative to sheep, cattle and deer. Although current bird prices are not sustainable, New Zealand and overseas experience to date suggest ostrich can be farmed successfully and profitability long term. Climate and terrain of the east coast of New Zealand suit ostrich physical requirements. It has been suggested that production systems will develop in which grazed herbage will provide 60% or more of the nutritional requirements. The ability to graze low-cost herbage combined with a reproduction rate of about 25 progeny per hen per year indicate that ostrich production systems may be three times more efficient than beef or deer at turning feed into lean meat. The low fat and low cholesterol meat is likely to be the primary product and is already being sold in international markets. There is also a market for the leather, feathers and oil by-products.

The atrophic rhinitis (AR) and pneumonia are among the most frequently diagnosed respiratory diseases in swine production systems and can lead to significant economic losses. The aim of this study was to determine the occurrence and degree of AR and pneumonia in hybrids and undefined breed swine herds submitted to intensive farming system and check if there is an association between the occurrence of these diseases in the herds. For this, we used 30 swines hybrids (Group I) and 30 undefined breed swines (Group II) from intensive farming system. The index of atrophic rhinitis (IAR) of herds for Groups I and II were, respectively, 1.00 and 0.57. In Group I, 20.8% (5/24) of the pigs presented pneumonia, while none of the animals in Group II exhibited this pathology. There was no correlation between the presence of atrophic rhinitis and pneumonia for the studied animals. These are the first data on the occurrence of these diseases in swines of Piauí State, Brazil. We demonstrated that these pathologies are present in animals from intensive farming systems and that occurrence varied according to racial type, being the hybrid swines the most affected animals by AR and pneumonia.

Beef production in New Zealand could be increased by developing farming systems that profitably utilised heifer and bull calves which would otherwise be slaughtered soon after birth. Evaluation of a once-bred heifer cattle policy over 3 years at Massey University showed that target weights to achieve acceptable calving percentages and final carcass weights can be achieved under pasture feeding. Piedmontese and Belgian Blue sires used over Friesian cows produced bull calves that did not grow significantly faster than straight Friesian animals, but had higher dressing out (57.8 ~56.7 y 54.0, P~0.05) and meat yield percentages (76.0 x.75.7 v 73.2 for Piedmontese, Belgian Blue and Fnesian, respectively). Both the once-bred heifer and the exotic x bull beef production systems earned greater returns than traditional beef cattle policies at 1992 costs and prices, and could be easily implemented by New Zealand beef producers.
