Encouraging lean pork production through promising herbal supplements
Lean growth rate, lean efficiency (the kg of feed per kg of lean), and total production dollar cost per kg of lean is important traits for the future. Pork carcasses are graded according to the amount of edible meat they will yield. Number 1 carcass is one having the most satisfactory ratio of fat to lean; Number 2, 3, and 4 have a higher proportion of fat, reducing the amount of lean.
Under typical market conditions, an increase in the lean growth rate of 5% will translate to at least an additional $1 profit/pig. Therefore, it is important to understand what contributes to differences in lean growth rates between groups of pigs and hope to identify the means to increase lean growth rates and the efficiency of pork production.
Lean growth rates can be calculated from carcass weight at slaughter, the estimated lean content in the carcass, and assumed lean content in a pig’s body at the initial weight and the amount of time required to grow from initial weight to slaughter weight.
What affects lean growth?
– Pig genotype
– Sex (Barrows and Gilts)
– Nutrient and energy intake- Lysine and other essential amino acids, and energy intake.
– Environmental stresses
The definition of lean and methods used to quantify the amount of lean that is present in pig carcasses may vary between and among packing plants, pig breeding organizations and research institutions.
To maintain efficient production in the growing pig it is necessary to understand the complex interactions that are involved. There are five important areas:
3. Type of housing
4. Quality of the environment
5. Genetic potential
6. The levels of disease and their economic effects
These are significantly demonstrated by the very marked improvements in daily gain and feed conversion achieved when pigs are segregated and early weaned, or produced under segregated disease control conditions.
Limitation and bans on synthetic additive use in the finishing pigs
The other market alternatives involve β-adrenergic agonists like Ractopamine HCl, Zilpaterol HCl, etc. These products increase muscle growth rate and improve feed efficiency while reducing fat deposition. In the US, ractopamine has been commonly used in commercial finishing operations according to regulations set by the FDA. This product is also used in the exhibition industry to enhance muscling and appearance in show pigs.
According to the Center for Food Safety (CFS), “The drug mimics stress hormones and increases the rate at which the animals convert feed to muscle.” In doing so, however, a number of adverse effects have been reported in pigs, including high-stress levels, lameness, hyperactivity, broken limbs and death. Problems with behaviour and cardiovascular, musculoskeletal, reproductive and endocrine systems have also been reported.
Only 26 major meat-producing countries allow ractopamine use, while at least 160 have banned it. It is controversial not only because it is linked to adverse effects in animals but also because of human health concerns.
Innovative and sustainable approach towards lean pork production
Phytogenic feed additives comprise a wide range of plants, like herbs, spices and other plant-derived products like essential oils and oleoresins.
The beneficial effect of herbs in pig farming is been increasing globally, especially encouraged by higher authorities. The studies have shown substantial effects on weight gain, carcass meat content, meat quality.
The commercial pork industry’s number one challenge is to provide consumers with safe, wholesome food of a high and consistent quality. This food should be produced as efficiently as possible, while considering the impact on the environment, animal welfare, and the well-being of people involved with the production process
Metalean, protein optimizer for high lean pork
Metalean is a phytogenic lean growth supplement for pigs. Metalean benefits in uniform growth performance, more than 10% improvement in the feed efficiency, improved carcass characteristics like higher dressing percentage, lower backfat thickness.
How does Metalean work?
The phytoactives in Metalean influence insulin-like growth factors which is one of the potent growth factors associated with the wide range of anabolic processes. The biological actions of IGF I are controlled mainly through the stomach, duodenum, and muscle tissue. This IGF targeted gut-brain axis is triggered by Metalean, which controls the fat and protein metabolism. It also upregulates fatty acid breakdown and limits fatty acid synthesis. Allium and Piper’s species also play a potential role in diet-induced thermogenesis.
Quality parameters of pork have shown superior results with Metalean supplementation. The meat colour, firmness, marbling, and water holding capacity is improved with the supplementation in the finishing phase of swine farming.
The natural and safe herbal feed supplement “Metalean” is an efficient alternative and sustainable solution for the pork industry. It is recommended to use at 2 kg per MT of finishing feed in the last 4 weeks before attaining desired body weight.
